For years, cybersecurity professionals have been repeating the same warning: Every company will eventually be breached. Fine. Let’s accept that. Then why do so many organizations still behave as if the near sole purpose of cybersecurity is to prevent the breach from ever happening? That is the contradiction at the heart of modern cybersecurity strategy. We say, “Assume the breach,” but we budget, govern, architect, and rehearse as if the wall will hold. We tell boards compromise is i

Direct messages sent via WhatsApp are being used to distribute malicious Visual Basic Script (VBScript) files that lead to the installation of legitimate Remote Monitoring and Management (RMM) software. Per findings from Kaspersky, the active campaign is targeting users of WhatsApp Desktop and WhatsApp Web across Malaysia, Brazil, India, Mexico, Singapore, the U.K., Spain, Taiwan, Australia,View the full article

OpenAI on Monday said it's releasing an improved version of its GPT‑5.5‑Cyber model to trusted defenders as part of the Daybreak initiative, the artificial intelligence (AI) company announced last month. Calling GPT‑5.5‑Cyber its "strongest model yet for finding and helping patch software vulnerabilities," OpenAI said the model can "sustain deeper analysis across large codebases" to identifyView the full article

CSOs must re-write their cyber risk strategies because threat actors are increasing using AI to evade defenses, says a group of national cybersecurity agencies – a call that one expert immediately complained is too vague to be of use. In its call to action on Monday, the group warned that “frontier Al models are anticipated to exceed current industry expectations, fundamentally transforming both offensive and defensive cyber capabilities. The timeline is not years, it is months.” Because

Stung by a surge in cyberattacks that have run amok in developer environments, GitHub has strengthened the security of actions/checkout to block ‘pwn request’ attacks that exploit insecure use of the pull_request_target workflow trigger to run an attacker’s code with the workflow’s full privileges. Announced on June 18, actions/checkout v7 now automatically blocks and fails workflows when used inside pull_request_target or workflow_run events when attempting to fetch unreviewed fork pull req

AI coding agents are making it easier than ever to produce software. Ensuring that software is secure before deployment is another matter — one that AWS thinks AI should help with too. As enterprises adopt agentic development workflows, the volume of first-party code being created and modified is rising rapidly. Yet the process of validating vulnerabilities, determining whether they are exploitable, and fixing them often still depends on developers and security teams working through findings

An attacker broke into competitive-intelligence vendor Klue, stole OAuth tokens its customers use to connect to Salesforce and other platforms, and accessed data across multiple customer environments prompting the company to revoke customer OAuth tokens and disable affected integrations. “An attacker gained access through a compromised legacy credential associated with an integration service,” Klue CEO Jason Smith said in a posting to the company’s blog. “The attacker used that access to obt

Cybersecurity researchers have disclosed details of four vulnerabilities in Dify, an open-source agentic workflow platform with more than 146,000 GitHub stars, that could allow attackers to stealthily read artificial intelligence (AI) conversions from other customers' applications without requiring authentication. The vulnerabilities have been collectively codenamed DifyTap by Zafran Security.View the full article

A heap over-read in the Squid web proxy can leak another user's cleartext HTTP request, including any credentials or session tokens it carries, to anyone already allowed to send traffic through the same proxy. The bug traces to a 1997 FTP-parsing change and is still live in Squid's default configuration. Researchers at Calif.io disclosed it in June and named it Squidbleed (View the full article

Canada's spy service got a judge's permission to reach into infected servers, home routers, and IoT gear sitting on Canadian soil and neutralize two foreign-run botnets. The Federal Court released a public version of the ruling on June 15. It is the first time the Canadian Security Intelligence Service has used its threat reduction warrant powers this way.

Attacks on AI systems and disinformation starred as key elements of a ransomware tabletop exercise CSO participated in during this month’s Infosecurity Europe conference. The “Enter the War Room” exercise — organised and run by cybersecurity vendor Semperis — featured a scenario focused on a cyberattack against a fictional supermarket chain, BlueCart. CSO took part as one of eight members of a red team of supposed national state–linked attackers (APT 64, AKA Checkout Chaos) that was as m

Longtime security leader Doug Kersten has expanded his list of responsibilities. As CISO of software maker Appfire, he now has accountability for business risks, such as how security tools and processes within customer products and services impact their costs and, thus, profitability. It’s a clearcut example, he says, of where and why CISOs must consider not purely security risk, but also business risk. “CISOs need to provide input and remediation on the impact of security cost becau

A new malware family is turning forgotten home routers into a distributed reconnaissance and proxy network, not the DDoS botnet these devices usually end up in. QiAnXin's XLab calls it AryStinger and counts at least 4,300 infected routers, a total it says is still rising. The distinction matters. AryStinger exists for the stage of an attack that comes before the break-in. InfectedView the full article

A new report from INTERPOL has revealed a "dramatic increase" in cybercrime in Asia and the South Pacific, fueled by rapid digitalization, internet penetration, new technologies, organized criminal networks, and a disparity in cybersecurity maturity. According to INTERPOL's 2025/2026 Asia and South Pacific Cyberthreat Assessment Report, phishing has emerged as the most widespread andView the full article

At Zenith Live 2026 held on 16-17 June in Vienna, Zscaler sharpened a reality that Southeast Asia CIOs and CISOs are already sensing, which are, AI agents are quickly becoming digital workers inside their organisations, while regulators tighten data residency rules and supply‑chain attacks move closer to core business operations. Zscaler’s solution is to extend its Zero Trust Exchange and SASE platform beyond users and workloads to AI agents, unmanaged devices, multi‑cloud workloads, and B2B pa

One of the world’s top ransomware groups has given its criminal affiliates access to advanced tools capable of successfully disabling many of today’s enterprise endpoint detection and response (EDR) products, new research by security company ESET has found. The group in question is The Gentlemen, which, since its appearance last year using this moniker, has become one of the most successful ransomware-as-a-service (RaaS) platforms thanks to a business model that gives affiliates an unusually

Dutch law enforcement authorities, along with counterparts from Canada , Germany, and the U.S., have disrupted malicious infrastructure associated with SocGholish and cleaned up nearly 15,000 infected WordPress websites.

Microsoft Office users may find that some of their applications are failing to open when called on by third-party applications. It’s an issue that has emerged after the latest round of Microsoft updates. The problem affects Word, Excel, and other Office applications opened from third-party offerings including CCH Engagement, Workpaper Manager, Zotero, or dental office software such as Dentrix or Softdent. The update issued on June 9 appears to have triggered problems with the OLE automat

A simple framework has always governed security operations that I call the SOC Triangle. It is a balance between quality, consistency and cost efficiency. Every SOC operates within it. Push for higher-quality investigations, deeper analysis, richer context, fewer missed signals and you pay for it in time and expertise. Standardize workflows to ensure consistency across every alert, and you often lose the flexibility needed to handle real-world complexity and nuance. Optimize for cost efficie

Salesforce has revealed that it disabled the Klue Battlecards app integration within its platform in response to a security incident impacting the competitive intelligence company on June 11, 2026. To that end, organizations will be unable to connect to Salesforce via the app until further notice, the American cloud-based software company noted in an alert published this week.

You are a security leader at a small or medium-sized business (SMB), and your organization has decided to adopt Claude. If you are like me, after the initial “surprise” wears off, you probably want to quickly get your arms around what adopting Claude means for the business, and for security specifically. Below are some lessons I learned, witnessed as a bystander or heard from fellow security leaders in the SMB space. The business wants to move fast, and Security is tasked with keeping up with th

Microsoft is warning of a novel remote code execution (RCE) path possible through web-enabled AI agents, demonstrating the technique against AutoGen Studio, its open-source interface for building and testing multi-agent applications. The demonstration showed that a malicious webpage rendered by an AutoGen-powered browsing agent could reach a local Model Context Protocol (MCP) service and run arbitrary processes on the host machine. Microsoft researchers dubbed the technique “AutoJack” be

A recent proof-of-concept attack against Microsoft’s M365 Copilot Enterprise highlights what could be a much broader prompt injection threat based on a common way many AI-enhanced web services operate. Dubbed SearchLeak, the attack hinged on a typical malicious objective: to leak sensitive corporate data by tricking employees to click on specially crafted links. To carry out the attack, researchers combined three weaknesses in the Copilot Enterprise Search implementation — one of which s

Apple has updated its Beats Studio Buds wireless earbuds to patch a high-severity vulnerability that could be exploited by nearby hackers to eavesdrop on users.

The Oracle Critical Security Patch update (CSPU) released this week contains 245 newly-announced fixes for supported on-premises software, some of which impact multiple products. It is in reaction to an industry trend to announce and fix security holes much more quickly, and complements Oracle’s traditional quarterly patch schedule. The current batch of patches affects a wide range of products, including Oracle Enterprise Manager, JD Edwards, Fusion Middleware, MySQL, Peoplesoft, and others

For the past four years, a sprawling Android-based botnet called Popa has forced millions of consumer TV boxes to relay Internet traffic linked to advertising fraud, account takeovers, and mass data-scraping efforts. This week, researchers from multiple security firms concluded that the Popa botnet is linked to NetNut, a “residential proxy” provider operated by the publicly-traded Israeli firm Alarum Technologies Ltd [NASDAQ: ALAR]. Malicious streaming devices sold online that enroll the user’s

Microsoft has disclosed details of a Windows-based cryptocurrency clipper campaign that has targeted users since February 2026.

Threat actors are abusing trusted platforms, including Google Ads, GitLab pages, and Claude’s shared chat feature, to trick users into executing malicious commands on their systems. Disguised as popular AI developer tools, the threat actors used ClickFix social engineering attacks, where victims were tricked into manually executing malicious commands. Typically, this involved copying and pasting PowerShell or terminal commands, noted researchers at TrendAI. The campaign funnelled more th

A massive credential-compromise campaign dubbed “Fortibleed” has been found to expose tens of thousands of Fortinet devices worldwide, with researchers warning of persistent attacker access to affected enterprise environments. The campaign was first flagged by security researcher Volodymyr Diachenko, who posted on LinkedIn about finding an attacker-controlled list of potentially working FortiGate passwords collected “through various means.” Further details came from SOCRadar after its te

For years we’ve heard the frightening prediction that AI will take jobs away from people. It will and it already is, but that doesn’t mean it won’t also create new jobs and skills demands — like every other labor trend driven by technology advances. Take security operations for example. Historically, security operations centers (SOCs) were built on a three-tier analyst model. Tier 1 analysts were junior personnel, paid to monitor activity and triage alerts. Their job was often described as “

Every major technology shift changes cybersecurity. I’ve spent much of my career working through major technology transitions, from the rise of the commercial internet to mobile and cloud computing. Each shift created new opportunities for innovation, but it also created new security problems organizations weren’t fully prepared for. AI may resemble previous technology shifts in some ways, but it differs in one important respect: it challenges one of the foundational assumptions modern secur

There’s no shortage of agentic AI tools out there that offer to perform online tasks on your behalf, if only you’ll give them all your passwords and credit card details. The trouble starts when those agents don’t know when to stop — or when others don’t know to stop them. In Estonia, the country’s AI Council has plans to change that, proposing to issue government-backed digital identities for AI agents that spell out what powers a person or company is willing to delegate to them. “In the

Reducing alert noise is one of the clearest promises in the move toward an agentic SOC. But better triage is not just about pushing alerts through faster. In this blog, we look at how agentic SOC workflows reduce noise, improve triage quality, and create a more usable path from signal to decision. View the full article

A design flaw in the Vertex AI software development kit (SDK) for Python, Google Cloud’s managed platform for building, training, and deploying AI agents, could allow hijacking and poisoning of models outside of a developer’s own Google Cloud project. According to Unit 42 researchers, a combination of bad bucket naming logic and missing authentication made it possible for an attacker to hijack the victim’s project by just knowing their project ID and region. “Since no two buckets across

Organizations racing to embed AI into business operations are realizing that the risk management frameworks they’ve relied on for decades aren’t built for the behaviors, failure modes, and ethical complexities AI systems introduce. Fortunately, a new generation of AI-specific frameworks has emerged to give organizations a structured way to identify where AI can go wrong, what controls to put in place, and how to demonstrate responsible AI use to regulators, customers, and investors. Not all

The 2026 Verizon Data Breach Investigations Report analyzed more than 22,000 confirmed data breaches across 145 countries. Its findings point to a single uncomfortable truth: organizations cannot patch fast enough to prevent every incident. Exploitation of vulnerabilities surged to become the leading initial access vector, the median time to remediate a critical flaw climbed to 43 days, and the volume of critical vulnerabilities grew 50% year over year. Even top-performing organizations only man

Despite best efforts by defenders, malicious emails continue to slip through the cybersecurity cracks, leading some enterprises to implement a layered “defense in depth” strategy that incorporates multiple tools. Microsoft seems to be challenging this idea, revealing that there are only nominal returns from adding integrated pre- and post-send partners to Defender for Office 365’s protections. According to its new quarterly benchmarking data, the tech giant catches the vast majority of m

Zero trust is 15 years old, and like many teenagers, it can feel misunderstood and underappreciated. The concept of zero trust was first defined by John Kindervag, a Forrester analyst at the time, as a strategy to replace the outmoded perimeter security model with a “never trust, always verify” approach. But going from principle to practice isn’t easy. Accenture reports that 88% of organizations have encountered significant challenges implementing zero trust. In a recent Gartner survey,

The North Korean state-sponsored hacking group known as ScarCruft (aka APT37) has been observed using spear-phishing messages impersonating Microsoft Account security notifications to deliver malware called NarwhalRAT.

Enterprises using the open-source AI orchestration platform Langflow are being urged to patch a high-severity path traversal flaw amid active exploitation, despite a fix having been available for more than two months. The bug, which stems from improper handling of filenames in Langflow’s file upload functionality, can allow attackers to write files to arbitrary locations within the affected system and, under certain conditions, can be used to achieve remote code execution (RCE) on affected s

Attackers can turn AI agent guardrails into denial-of-service weapons, according to new research that found a single poisoned document can dramatically slow shared AI agent workflows by trapping reasoning-based safety systems in extended thinking loops. “Reasoning-based guardrails introduce a new attack surface where security mechanisms themselves become the target,” the researchers from Hong Kong University of Science and Technology and collaborators wrote in the paper. They added that

Employee onboarding is a busy time for IT teams. New starters need devices, accounts, access permissions, and passwords, all delivered within a tight timeframe. That usually means sharing a temporary "first-day" password so employees can access systems for the first time. The issue is that these passwords don't always stay temporary. They may be sent over email or SMS, reused across accounts,View the full article

Every enterprise security team is fighting a workforce problem they cannot see on any org chart. Bots, service accounts, API keys, OAuth tokens, machine certificates — non-human identities now outnumber human ones in most large organisations, often by a factor of ten to one. They authenticate constantly, operate across every environment, and when forgotten, they do not retire gracefully. They linger, accumulate privilege, and wait. Security practitioners have taken to calling them ghost iden

An attacker tampered with trusted JavaScript files used by WordPress sites running PushEngage, OptinMonster, and TrustPulse, turning those files into a way to break into the sites. When a site administrator was logged in as the file loaded, the code created an admin account under the attacker's control and installed a hidden plugin that opened a way back in.

Your board is asking. Your legal team is asking. Your auditors will be asking: Should AI workloads move to sovereign cloud, or stay on AWS, Azure or GCP? European enterprises have already run this experiment — under real regulatory pressure, with real money and real consequences. Many discovered that sovereign cloud alone didn’t deliver the control they expected. The real control point turned out to be somewhere else entirely. Europe ran this experiment first, under regulatory pressure US en

In June 2025, Simon Willison, the engineer who coined the term “prompt injection,” published a warning that circulated widely through the security community. He called it the lethal trifecta — three capabilities that, when combined in a single AI agent, create a near-guaranteed path to exploitation through indirect prompt injection: access to private data; exposure to untrusted content; the ability to communicate externally. The framing was sharp and useful. If your agent reads your email, i

A disgruntled researcher who has been publishing zero-day Microsoft Windows vulnerabilities for the past several months released a new exploit Thursday that promises to bypass BitLocker encryption on locked devices. A well respected security expert reported that the exploit doesn’t work as initially described, but the researcher is looking for ways to fix it. Dubbed GreatXML, the exploit is supposed to work from the Windows Recovery Environment (WinRE), a special boot mode in Windows from wh

Lawmakers have failed to extend a surveillance law that allows US intelligence agencies to monitor targets abroad without a warrant. Congress rejected a vote to extend Section 702 of the Foreign Intelligence Surveillance Act to July 2, which means, for a few days at least, some surveillance will be put on hold, for the first time since the Act was passed in 2008. The next possible chance for a vote will be June 28. This has significance for CISOs because they need to be aware of how comm

An intruder has breached the French government’s encrypted messaging service, Tchap, showing once again that human error is a weak spot in any security system. Tchap was developed in France as an example of national sovereignty and was designed to be a more secure option than WhatsApp for communication between government employees. In this case, it wasn’t the technology that was at fault, but a user: The intruder gained access to the system by taking over their account, according to DINU

Today’s AI web agents have no dependable defenses against prompt injection, according to new research showing that not a single attack scenario was consistently blocked across leading systems powered by GPT‑5 and Gemini. The findings come from StakeBench, a stakeholder-centric benchmark developed by researchers from Nanyang Technological University, ST Engineering, IBM Research, and the University of Illinois Urbana-Champaign to evaluate prompt injection attacks against AI agents operating i

A newly disclosed Oracle PeopleSoft zero-day became the weapon of choice in a recent ShinyHunters extortion campaign that primarily targeted universities and other educational institutes.

Quantum technology may feel far off but certain risks are already with us in the form of “harvest now, decrypt later” — an attack vector in which malicious actors steal data now for a future in which they have access to quantum computational tools capable of breaking encryption deployed by most companies today to protect their data. Despite increasing discussion surrounding this issue, not all organizations are aware of the risk. According to a 2025 ISACA survey, only 5% of cyber professiona

ServiceNow is notifying customers after discovering and remediating a vulnerability that could have exposed data via an unauthenticated API endpoint on affected instances. The issue emerged publicly after customers began discussing security notifications from ServiceNow and reports of suspicious activity linked to their environments. According to the company’s advisory, the vulnerability was initially reported through ServiceNow’s bug bounty program in April, prompting an investigation a

As security operations become more autonomous, the real question is not whether humans stay involved. It is where their involvement matters most. In this blog, we break down what should stay human in an autonomous SOC, what can move into agentic workflows, and how oversight needs to be designed so it is meaningful instead of symbolic.

The future of reliability will not be defined by whether site reliability engineering (SRE) teams use AI agents, but by the conditions under which they choose to trust them. In high-stakes systems, trust is never granted because a demo looks impressive; it is earned through observability, constraints, accountability and repeated evidence that the system helps more than it harms. Right now, many teams are exploring AI for incident response, alert triage, root cause analysis and runbook automa

A botnet made up of compromised small office and Internet of Things devices has grown into a larger reconnaissance network capable of rapidly identifying vulnerable internet-facing systems after public vulnerability disclosures, researchers said. The botnet, tracked by Lumen’s Black LotusLabs as JDY, now comprises more than 1,500 compromised small office and home office, or SOHO, and IoT devices, and is being used to “discover, fingerprint and continuously map exposed services at scale.”

I’ve spent the past two years working on incident response and threat intelligence, and the pattern I’m about to describe is one I keep seeing show up in cases that should have been caught at the email gateway.

Security teams’ patching practices have come under intense pressure over the past year, as active exploitation is up, time-to-exploit windows are accelerating, and vulnerabilities have become attackers’ top initial access vector of choice. Last year, organizations fully remediated only 26% of the vulnerabilities that attackers were actively exploiting in the wild — down from 38% the year before, according to Verizon’s 2026 Data Breach Investigations Report. The median time to close those kno

IT software provider Ivanti fixed two vulnerabilities in Ivanti Sentry, a secure mobile gateway appliance formerly called MobileIron Sentry. The flaws could allow unauthenticated remote attackers to gain complete control of deployments. One of the vulnerabilities, CVE-2026-10523, credited to researcher Bryan Lam, allows attackers to bypass authentication and create arbitrary administrative accounts on appliances. The flaw is rated with a severity of 9.9 out of 10 on the CVSS scale. The s

The researcher said their exploit uses a race condition problem affecting Microsoft Defender, giving attackers less than a hundred percent od

AI agents given access to corporate email and business applications could become a new phishing target for attackers, according to cybersecurity researchers, after a test agent built on OpenClaw was tricked into sharing cloud credentials and customer data with an external attacker. Varonis Threat Labs said it built an OpenClaw AI agent called Pinchy to test whether autonomous agents could fall for the same kinds of phishing attacks that have long targeted employees. Varonis tested the agent

When Ram Shankar Siva Kumar launched Microsoft’s AI red team in 2019, the discipline barely existed. “The running joke used to be that people who used to work in AI red teaming, you can round them up in a 14-foot catamaran,” he tells CSO. At the time, Microsoft’s approach looked familiar to anyone in cybersecurity: Attack machine learning systems the same way security teams attacked everything else.

UK Prime Minister Keir Starmer’s speech on Monday insisting that tech companies create device controls to somehow block children from viewing or creating sexually explicit imagery has raised alarms among CISOs, who worry that the same technology could undermine enterprise security. Starmer gave tech firms three months to create and implement such restrictions voluntarily, at which point he said he would push for legislation to make it mandatory. Behind the technical and logistical hurdles fo

AI-generated code is riddled with security flaws, yet enterprises are shipping more of it than ever before. Why? Perhaps they’re over-confident, lack true visibility into security risks, or are simply choosing to ignore the problem and hope it goes away. It’s a dangerous game to play at the dawn of the agentic AI era, as underscored in a new report from app security company Checkmarx. The survey of thousands of security leaders exposes an underlying naivete about AI-built code and its vu

Microsoft today released software updates to plug nearly 200 security holes across its Windows operating systems and supported software, a record number of fixes for the company’s monthly Patch Tuesday cycle. Nearly three dozen of those bugs earned Microsoft’s most dire “critical” rating, and exploit code for at least three of the weaknesses is now publicly available. The software giant said in a blog post last month that both its engineers and the security community are increasing using artifi

Anthropic unveiled two new powerful AI models built on its previously restricted Mythos architecture: Claude Fable 5, which is being made broadly available, and Claude Mythos 5, which remains limited to a small group of cybersecurity and infrastructure partners. Anthropic describes Fable 5 as the most capable model it has ever released to the public, outperforming previous Claude models across software engineering, scientific research, vision, and complex knowledge-work tasks. Anthropic says

Meta on Tuesday announced that it will use information shared by other businesses to personalize users' feed and responses from its artificial intelligence (AI) chatbot, expanding its scope beyond targeted ads. "Businesses often share information about people's activity on their sites with us to make ads more relevant," Meta said in a statement. "We already use this data - like games you playView the full article

Veeam has released security patches to address a critical flaw in its Backup & Replication software that could result in remote code execution. Tracked as CVE-2026-44963, the vulnerability carries a CVSS score of 9.4 out of a maximum of 10.0. "A vulnerability allowing remote code execution (RCE) on the Backup Server by an authenticated domain user," Veeam said in a Tuesday advisory. ItView the full article

Microsoft on Monday confirmed that it temporarily removed some GitHub repositories in response to a recent security incident that led to 73 of its open-source projects being compromised to inject an information stealer into the code. "Our priority is to protect customers and the broader ecosystem," a Microsoft spokesperson told The Hacker News via email. "We temporarily removed someView the full article

Check Point has issued emergency hotfixes for a pair of vulnerabilities affecting VPN deployments that still use the deprecated Internet Key Exchange version 1 (IKEv1) protocol, warning that one of the flaws is already being exploited in the wild. The more serious issue allows attackers to establish VPN sessions without a valid password, potentially giving them a foothold inside corporate networks. According to the company, attackers have been exploiting the vulnerability since at least earl

Cybercriminals are increasingly reshaping familiar social-engineering campaigns around the way employees use AI, with separate advisories from Microsoft and Google documenting how attackers are adapting scams to AI-powered tools, trusted digital services, and changing workplace behavior. Microsoft Threat Intelligence, in its advisory, said threat actors are “leveraging the wider global interest around AI itself as a social engineering lure,” impersonating platforms such as ChatGPT, Microsoft

Researchers from the University of Toronto developed a computer worm prototype powered by an AI agent that successfully self-replicated to different systems within a simulated computer network. The worm used a free large language model (LLM) running on local hardware and exploited a combination of older and new vulnerabilities, as well as misconfigurations that remain all too common in enterprise environments. At a time when CISOs and the security industry are concerned about the ability of

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a high-severity flaw impacting BerriAI LiteLLM to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2026-42271 (CVSS score: 8.7), is a command injection vulnerability that could allow any authenticated user to run arbitrary commands on theView the full article

Threat actors are continuing their onslaught against software supply chains, now with malware named after death itself. The newly-discovered Hades Campaign is a “highly sophisticated” supply chain compromise that targets Python developer environments and runs as soon as infected packages are imported. It uses the popular Bun toolkit to silently execute multi-layer payloads that can extract sensitive data, move laterally across compromised systems, exploit common security frameworks, and even

OpenAI’s move to implement a Lockdown Mode that tries to limit data exfiltration by shutting down external capabilities is being seen as making the best out of a bad situation. But Lockdown Mode doesn’t block exfiltration as much as it slightly reduces it, and the reality of enterprises using multiple AI vendors for their agentic models further complicates an already dicey governance strategy. When activated within OpenAI products’ settings, Lockdown Mode limits web browsing to cached conten

Cisco warns customers of an actively exploited high-severity vulnerability in Catalyst SD-WAN Manager, an enterprise network management system that has been targeted by hackers multiple times in the past. Located in the command-line interface, the flaw allows authenticated attackers to escalate privileges to root and take over the entire system. The vulnerability, tracked as CVE-2026-20245, is rated 7.8 (high) on the CVSS scale instead of critical because it requires local access and netadmi
