Monday recap. Same mess, new week. A sketchy dev tool got people pwned, old bugs came back from the dead, and security products somehow needed protecting from themselves. A bunch of companies spent the week checking old boxes and forgotten servers they should've patched years ago. Good times. Phishing crews are getting smarter too - less obvious scam junk, more targeted stuff that actuallyView the full article

Authorities in the Netherlands have arrested the co-owners of two related Internet hosting companies for operating IT infrastructure used by Russia to carry out cyberattacks, influence operations and disinformation campaigns inside the European Union. The two men were the focus of a 2025 KrebsOnSecurity story about how their hosting companies had assumed control over the technical infrastructure of Stark Industries Solutions, an Internet service provider sanctioned last year by the EU as a frequ

Enterprises cannot secure AI agents by making the underlying models more robust and must instead enforce security controls at the system level around them, researchers behind a paper published this month argued, warning that traditional AI-security approaches are increasingly misaligned with how autonomous agents actually operate inside enterprise environments. The paper argues that enterprises should stop treating AI agents as trusted software components and instead secure them as fundament

Threat actors are exploiting a recently disclosed critical security flaw in Ghost CMS to inject malicious JavaScript code with an aim to fuel ClickFix attacks. According to QiAnXin XLab, the activity involves the exploitation of CVE-2026-26980 (CVSS score: 9.4), an SQL injection vulnerability in Ghost's Content API that could allow an unauthenticated attacker to read arbitrary data from theView the full article

Ask a cybersecurity pro about Network Detection and Response (NDR) and you might still hear "Noisy," "Too much data." But ask the teams running NDR that includes agentic AI capabilities and you'll hear they're actually using it to catch threats earlier, triage faster, and chase fewer false positives. The old complaint lingers in part because reputations are sticky, and because NDR has evolvedView the full article

If you were hit by ransomware tomorrow, would you pay to get your data back? That’s what more than half of CISOs in a recent survey said their organization would do. It’s a situation more companies are going to face in future. “Attacks are increasing and continuing to increase,” said Christy Wyatt, CEO of security vendor Absolute Software, which commissioned the survey. “Companies are better prepared to deal with them: Some of the training is paying off and AI is helping. But remember that a

A new coordinated cross-ecosystem software supply chain attack campaign has targeted npm, PyPI, and Crates.io to distribute credential-stealing malware. The campaign, codenamed TrapDoor, spans more than 34 malicious packages across over 384 versions.

Chromium — the open-source browser that underpins Google Chrome, Microsoft Edge, and Opera, among others — contains an unpatched vulnerability that attackers can exploit to execute JavaScript code persistently across browser restarts. As a result, the flaw can be used to hijack users’ browsers for distributed denial-of-service attacks, run crypto miners, and more. The vulnerability was reported over three years ago by independent researcher Lyra Rebane and remained unfixed, or at least parts

The FBI has warned of the danger from anew wave of phishing attacks generated by a tool called Kali365. It enables cyber criminals to obtain Microsoft 365 access tokens and bypass multi-factor authentication (MFA) protocols without intercepting the user’s credentials by capturing Oauth tokens linked to the victim’s Microsoft 365 account. The scam works in a similar way to most phishing attacks. An attacker sends an email purporting to be from a trusted cloud document sharing service, inc

European authorities have cracked down on a VPN that has been used for various criminal activities. The operation, led by investigators in France and the Netherlands with help from Europol and Eurojust, has dismantled First VPN, a service that has been heavily promoted within Russia as a way of evading law enforcement. Criminals used it to conceal their identities and infrastructure while carrying out ransomware attacks, large-scale fraud, data theft, and other serious offences. While Fi

Lawmakers in both houses of Congress are demanding answers from the U.S. Cybersecurity & Infrastructure Security Agency (CISA) after KrebsOnSecurity reported this week that a CISA contractor intentionally published AWS GovCloud keys and a vast trove of other agency secrets on a public GitHub account. The inquiry comes as CISA is still struggling to contain the breach and invalidate the leaked credentials. On May 18, KrebsOnSecurity reported that a CISA contractor with administrative acces

Microsoft is testing the addition of agentic AI to its corporate browser, Edge for Business.A new version, currently available in a limited preview, will help perform routine tasks more efficiently, according to Microsoft’s partner product manager for Edge, Lindsay Kubasik. Agentic AI will help with completing multi-step tasks such as filling in forms, navigating sites, or gathering information from different tabs, all using enterprise-managed tools, the company said.

I spent two days at a substation connecting a major offshore wind farm to the grid. The control room featured three new AI-ready dashboards and a board mandate to “leverage machine learning for resilience.” It also had a maintenance laptop running Windows 7, literally taped to the inside of a cabinet because the Velcro had failed. That laptop was the only device in the building that could still talk to the legacy protection relays guarding the grid connection. No patches since 2017. No EDR.

The “retro” way “The thing about the old days is… they are the old days” – Slim Charles, The Wire Protecting a specified network perimeter was the main focus of enterprise security strategy for several decades. Businesses made significant investments in firewalls, intrusion detection systems, endpoint security and segmentation controls, all of which were built on the premise that an organization would stay safe if attackers were prevented from accessing the network.

A critical vulnerability in the on-premises version of the Cisco Secure Workload security platform could allow a threat actor to obtain the privileges of a site admin, enabling them to compromise endpoints and read or modify configuration data. “CSOs need to drop what they are doing and patch this immediately,” warned consultant Robert Enderle, who heads the Enderle Group. “Cisco Secure Workload manages zero trust, micro-segmentation, and enterprise-wide network visibility. If an attacker co

Microsoft released emergency fixes for two zero-day vulnerabilities in the malware protection components of Microsoft Defender. The flaws allow local attackers to gain system-level privileges or cause the anti-malware service to stop working correctly. Both conditions are valuable in a malware attack, first to prevent detection if the system relies only on Microsoft endpoint protection and second to gain full control over the system. On Wednesday, the United States Cybersecurity and Infr

Canadian authorities on Wednesday arrested a 23-year-old Ottawa man on suspicion of building and operating Kimwolf, a fast spreading Internet-of-Things botnet that enslaved millions of devices for use in a series of massive distributed denial-of-service (DDoS) attacks over the past six months. KrebsOnSecurity publicly named the suspect in February 2026 after the accused launched a volley of DDoS, doxing and swatting campaigns against this author and a security researcher. He now faces criminal h

Researchers have published details about a critical vulnerability in ChromaDB that could allow unauthenticated attackers to execute arbitrary code and access sensitive data on machines running the open-source vector database. The issue, tracked as CVE-2026-45829, is located in ChromaDB’s API server and was published by researchers at HiddenLayer after reportedly failing to get in contact with the developers of ChromaDB, one of the most popular vector databases used for AI applications.

Consider a cached access key on a single Windows machine. It got there the way most cached credentials do - a user logged in, and the key stored itself automatically. Standard AWS behavior. No one misconfigured anything or violated a policy. Yet that single key, which was easily accessible to a minor-league attacker, could have opened a path to some 98% of entities in the company's cloudView the full article

Microsoft has open-sourced two new tools aimed at bringing AI safety checks much earlier into the agent development lifecycle. The tools, called Rampart and Clarity, were announced this week as part of Microsoft’s broader push to operationalize safety engineering for agentic AI. “We built these tools because we believe that AI safety has to become a continuous engineering discipline rather than a periodic checkpoint, and we think the best way to make that happen is to put practical, open

The cybersecurity profession is on the verge of a sea change, and security pros must begin to master AI tools to combat emerging threats by building more autonomous, real-time protections.

A newly disclosed macOS infostealer campaign is exploiting user trust in some of the biggest names in tech to slip past defenses.  Researchers at SentinelOne have detailed a new variant of the SHub malware family, dubbed “Reaper,” that impersonates Apple, Google, and Microsoft at different stages of a single attack chain targeting Mac users. The SHub stealer family, identified two years back, previously used variants relying on fake installers and ClickFix-style social engineering, often pro

On April 22, for roughly 90 minutes, a malicious version of Bitwarden CLI appeared on npm. Version 2026.4.0 contained a credential-stealing payload that executed an obfuscated loader and harvested AWS, Azure, GCP, GitHub, and npm tokens from any developer machine that ran npm install. The attackers reached Bitwarden’s npm publishing path through a compromised GitHub Action related to the Checkmarx supply chain incident that affected several other downstream consumers that week. About nine da

Grafana Labs, on May 19, 2026, said an investigation into its recent breach found no evidence of customer production systems or operations being compromised.

Microsoft has disrupted the infrastructure powering the largest malware code-signing service used to help ransomware groups and other cybercriminals make malicious programs harder to detect on Windows. The threat actors behind the service used stolen identities and impersonated legitimate organizations to obtain more than 1,000 code-signing certificates. Microsoft seized the group’s website, signspace[.]cloud, revoked the abused certificates, which were obtained through its Artifact Signing

Until a few days ago, a publicly-accessible GitHub repository exposed credentials for both US government AWS accounts and internal Cybersecurity and Infrastructure Security Agency (CISA) systems. That’s according to cybersecurity reporter Brian Krebs, who first broke the news over the weekend, acting on a tip from researcher Guillaume Valadon at GitGuardian. Valadon confirmed the information in an email interview with CSO. Based on the repository’s commit history and the account crea

The world’s largest open-source registry, node package manager (npm), has been hit by another fast-moving malware attack, this time targeting the widely-used AntV enterprise data visualization tool. Unlike last week’s high-profile npm attack on TanStack, which exploited a complex GitHub Actions cache poisoning weakness, the latest incident early on May 19 took the more conventional route of compromising the credentials of a high-value npm maintainer account. According to analysis by Safe

Faced with the growing volume of submission to its bug bounty program, GitHub is replacing cash bounties with swag rewards for reports with low security impact — and asking researchers to stop submitting reports that are low quality or about things that aren’t its fault. The cloud-based code repository platform has seen a sharp increase in submissions that don’t demonstrate real security impact over the past year due to newer tools such as generative AI. “Not every valid submission repre

Microsoft’s aging “mshta.exe” utility, a leftover component from Internet Explorer, is still being actively abused in modern malware campaigns years after the browser itself was retired. According to new research from Bitdefender, attackers continue to abuse Microsoft HTML Application Host (MSHTA), a built-in Windows utility capable of executing VBScript and JavaScript from local or remote files. Despite Internet Explorer reaching the end of life in 2022, MSHTA is packaged by default on

Despite strong and redundant defenses, enterprises remain vulnerable to a wide range of cyberattacks. And because attacks — and cyber incidents — are inevitable, developing an incident response and recovery process that’s quick, comprehensive, and coordinated is essential. Expediting incident recovery time is critical because the longer an outage persists, the more costs, risk, and business disruption issues will compound, says Sharon Chand, US cyber defense and resilience leader at professi

There is a conversation that happens in boardrooms every quarter that security leaders will recognize. The CISO presents the threat landscape. The board asks what the company needs. The answer, almost always, is another tool. Another platform, another module, another vendor to close the latest gap. The budget gets approved. The tool gets deployed. And six months later, the conversation happens again because the gap didn’t actually close. It just moved. This pattern has been running on repeat

Waymo recently crossed a major milestone: Over 170 million autonomous miles driven without a single serious crash or injury. For years, autonomous driving was treated as a promise that was always just out of reach — too complex, too risky and not ready for the real world. That argument is no longer credible. Autonomous systems are now outperforming humans in high-speed, high-volume environments. That is not because they are perfect, but because they are faster in the moments that matter. Thi

Unlike most cyber security regulations, the EU’s Cyber Resilience Act is about product safety rather than processes or certification, extending the CE mark from the physical side of products to software, firmware, backend services, and anything with a network connection.

Linux admins reeling from handling last month’s CopyFail and last week’s Dirty Frag kernel vulnerabilities have a new headache to deal with: Fragnesia. “This is a significant vulnerability,” Robert Beggs, head of incident response firm DigitalDefence, told CSO. “It is bypassing traditional filesystem permissions that are present and enforced (for example, ‘file is owned by root’, or ‘file is read-only’) to allow manipulation without touching the disk.” Similar to Dirty Frag, Fragnesia (C

A widely active phishing-as-a-service (PhaaS) operation known as FlowerStorm has begun using a browser-based virtual machine to conceal credential theft code, marking what researchers say is an escalation in phishing-kit sophistication that could make attacks harder for traditional email and static-analysis tools to detect. Researchers at Sublime Security said in April that they identified the campaign, which used KrakVM, an open-source JavaScript virtual machine recently published on GitHub

A newly disclosed authentication bypass flaw in the open-source AI orchestration framework PraisonAI was probed by internet scanners less than four hours after its public disclosure.

Cybersecurity leaders often have complex relationships with their boards. Many boards lack cyber expertise, and CISOs can encounter roadblocks as a result when it comes to earning board approval. Other security leaders may not have a direct line to their board, or they may be viewed as too technical to win the support needed. One way some CISOs are working to improve that relationship is by becoming board members themselves to better understand what is important and how to communicate to boa

Microsoft has unveiled a new AI-driven vulnerability discovery system that identified 16 previously unknown Windows vulnerabilities, including four critical remote code execution flaws, in what security analysts say could mark a major shift in how software vulnerabilities are discovered and remediated. The system, codenamed MDASH, was developed by Microsoft’s Autonomous Code Security team alongside the Windows Attack Research and Protection group. The platform will enter private preview

Palo Alto Networks has launched Idira, a new identity security platform aimed at securing human users, machine identities, and AI agents amid the rising adoption of autonomous AI systems amongst enterprises. The company is positioning Idira as a next-generation identity security platform that goes beyond traditional privileged access management (PAM) systems by applying dynamic privilege controls across every type of identity inside an enterprise. “For most of the last two decades, ident

ClickFix, a one-shot social engineering technique that tricks victims into executing malicious workflows disguised as fixes to technical issues in their systems, has got a persistence upgrade. In a one-off instance, ReliaQuest researchers have spotted an intrusion chain using scheduled tasks, PowerShell-based command-and-control (C2), and a unique abuse of the decade-old open-source proxy tool PySoxy. As the researchers pointed out in a blog post, PySoxy is giving attackers encrypted pro

The US Cybersecurity and Infrastructure Security Agency (CISA) and its G7 cyber agency partners have released a list of minimum elements for an AI software bill of materials, a move that could help CISOs assess the security and provenance of AI systems entering enterprise environments. The guidance extends traditional SBOM concepts into AI by calling for documentation of models, datasets, software components, providers, licenses, and other dependencies. The supplemental minimum elements are

The annual CSO Awards annually recognize security projects that demonstrate outstanding security leadership and business value. For this year’s program, CSO honors 64 security organizations whose hard work and innovative approaches have had a significant impact on how their enterprises navigate risks in an increasingly challenging cyber environment. These projects showcase the variety of strategies that CISOs and their teams are employing to bolster enterprise security today. Many levera

Cybersecurity researchers are calling attention to a new campaign dubbed GemStuffer that has targeted the RubyGems repository with more than 150 gems that use the registry as a data exfiltration channel rather than for malware distribution. "The packages do not appear designed for mass developer compromise," Socket said. "Many have little or no download activity, and the payloads are repetitive,View the full article

Gorodenkoff / Shutterstock Die Google Threat Intelligence Group (GTIG) warnt davor, dass kriminelle Hacker mittlerweile KI einsetzen – sowohl, um Schwachstellen aufzuspüren, als auch um anschließend Malware zu entwickeln, die diese aktiv ausnutzt. Der Anlass: Im Rahmen der eingehenden Analyse einer Angriffskampagne prorussischer Hacker haben die Sicherheitsexperten nach eigenen Angaben erstmals einen KI-basierten Zero-Day-Exploit „in freier Wildbahn“ entdeckt. System-Management-Too

Google on Tuesday unveiled a new opt-in Android feature called Intrusion Logging for storing forensic logs to better analyze sophisticated spyware attacks. Intrusion Logging, available as part of Advanced Protection Mode, enables "persistent and privacy-preserving forensics logging to allow for investigation of devices in the event of a suspected compromise," the company said. The feature, itView the full article

Critical vulnerabilities in Windows Server’s networking and identity infrastructure, as well as a serious hole in Microsoft Dynamics 365 on-premises version, highlight Microsoft’s May Patch Tuesday fixes. They are among the 118 vulnerabilities identified this month by the company. Some in cloud-based services like Azure and Microsoft Teams have already been fixed, so no admin action is needed. But among the most severe that CSOs need to pay attention to is yet another hole in Windows Net

Artificial intelligence platforms may be just as susceptible to social engineering as human beings, but they are proving remarkably good at finding security vulnerabilities in human-made computer code. That reality is on full display this month with some of the more widely-used software makers — including Apple, Google, Microsoft, Mozilla and Oracle — fixing near record volumes of security bugs, and/or quickening the tempo of their patch releases. As it does on the second Tuesday of every month

The TeamPCP threat group has pulled off another big supply chain attack which within a few hours this week was able to successfully compromise 170 Node Package Manager (npm) and PyPI packages. The attack affected the entire TanStack Router ecosystem (@tanstack) of 42 packages, a routing library hugely popular among React web application developers. Multiple other packages were also affected, including @squawk (87 packages), @uipath (66 packages), @tallyui (30 packages), @beproduct (18 packag

OpenAI has unveiled Daybreak, its answer to Anthropic’s Claude Mythos, amid a growing market for frontier AI-powered cyber defense platforms. The initiative combines OpenAI’s large language models, Codex’s agentic capabilities, and integrations with the broader enterprise security ecosystem.
