Have you ever watched a military cyber ops team go to work responding to a cyberattack simulation? It’s like that scene from Die Hard 4.0 when all the screens start flashing red and systems start shutting down; however, unlike the movies, where bumbling government IT workers are caught out and panicking, our military actually moves with practiced precision to understand, contain, and mitigate the threat. Everybody understands their roles and any gaps are quickly highlighted and handled. This is

As CISOs know, an effective security program cannot be static. Rather, it must adapt to the evolving threat landscape and an ever-changing business environment. To adapt and improve, CISOs must continuously evaluate their existing program. That starts with asking tough questions about their performance, investments, and strategies. Here, security leaders share 15 questions every CISO should ask to ensure their programs can meet current demands and future needs. 1. What issue or incid

Security researchers are warning of an issue with the default HTTP/2 configuration used by major web servers which reportedly survived more than a decade of human review before showing up in Codex-assisted analysis. A flaw in the handling of the HTTP/2 protocol made a denial-of-service (DoS) attack possible on web servers including nginx, Apache HTTP server, Microsoft IIS, Envoy, and Cloudflare’s Pingora, according to security consultancy Calif.

CIOs rushing to roll out AI agents without real visibility into their decision-making processes are flirting with disaster. According to AI experts, deploying agents without observability processes and tools creates a ticking time bomb with the potential for huge negative consequences. Many companies are deploying AI agents and expecting them to increase productivity with little human intervention, observes T.J. Marlin, CEO of AI security firm Guardrail Technologies. That’s the wrong app

For decades, cybersecurity was a battle of skill. Elite attackers versus elite defenders. The rules of engagement were understood, even if the playing field wasn’t level. If you hired better analysts and bought better tools, hopefully you hardened your systems well enough and built detection capabilities that wore out the adversary’s patience. That era is over, and most security programs haven’t fully processed what replaced it. Adversarial AI has industrialized exploitation. What once requi

Online or telephone IT support scams have been tricking employees into downloading or clicking on malware for years. But according to the FBI, one group that targets US-based law firms has recently found success in person, by convincing firms to allow a supposed IT support person into the building, where they insert a storage device into a victim’s computer and install malware or steal data. This revelation comes from an FBI Flash report this week describing the activities of a gang it calls

A single malformed character in a web request can let an unauthenticated attacker slip past the access controls that guard applications built on Starlette, the open-source Python framework that powers FastAPI, researchers said. The flaw, tracked as CVE-2026-48710 could allow attackers to bypass host-validation protections using malformed Host headers, according to an advisory from cybersecurity firm X41 D-Sec. The attacker needs no password and no action from a victim, it said. Starl

For most of my career running security operations, the shape of cyber conflict has been defined by who could move faster than the other side. Faster at identifying a vulnerability, faster at patching, faster at detecting, faster at responding. The last few months have made me reevaluate that framing. Speed still matters. It just no longer carries the picture on its own. Scale and autonomy have moved alongside it, and the relative emphasis I place on the three is something I expect to keep adjust

Data security posture management (DSPM) explained Data security posture management (DSPM) tools help security teams examine their entire data environment to find shadow data, reducing the risk of data loss. Tracking down sensitive data across both cloud and on-premises systems can be vexing. Each environment presents its own challenges. Given the dynamic and ephemeral nature of cloud computing, cloud data is easily created, deleted, or moved around. The cloud attack surface is equally dy

Microsoft is previewing a new automatic device isolation capability in Defender for Endpoint’s auto attack disruption tool to help security pros contain cyber attacks in progress on their IT networks. The company announced the capability earlier this month in a column about new features in Defender. There’s no word on when automatic device isolation will be in full production. However, a new SANS Institute research paper warns that, in certain conditions, an attacker could leverage the n

The Iranian hacking group known as MuddyWater has been linked to a new campaign affecting at least nine organizations across nine countries on four continents in the first quarter of 2026. The activity targeted industrial and electronics manufacturing, education and public-sector bodies, financial services, and professional services, per the Threat Hunter Team from Symantec and Carbon Black.View the full article

A large-scale automated GitHub backdooring campaign was caught pushing thousands of malicious commits into public repositories while posing as routine CI/CD upkeep. Researchers at SafeDep observed the campaign, Megalodon, touching more than five thousand repositories over a six-hour window on May 18. The attack was in the form of a malicious commit, “acac5a9,” targeting GitHub Actions workflows. Unexpected workflow_dispatch runs in the Actions tab could be a warning sign, the researchers

A malicious package campaign across npm, PyPI, and Crates.io has put developer workstations back under scrutiny, after researchers said it targeted developer workflows and AI coding assistant files. Researchers at Socket said the campaign, which they are tracking as TrapDoor, “spans more than 34 malicious packages and 384+ related versions and artifacts” across the three open-source ecosystems. The packages were designed to steal developer secrets, including AWS credentials, GitHub token

Multi-factor authentication (MFA) was supposed to close a critical gap in identity security. It meant that, even if an attacker possessed the account credentials, they couldn't log in without the second factor. While that logic was sound, attackers have now figured out that they don't need to steal the second factor: they just need the user to hand it over. If your workforce authenticates withView the full article

I’ve spent years building compliance into security products. FedRAMP and Department of War Impact Level authorizations, vulnerability management pipelines: They all follow the same pattern. Build the product, then prove it meets requirements. The compliance layer sits outside the engineering workflow. It reviews what already exists. That model worked when the product stayed static between audits. It breaks for AI. AI systems change even when the base model does not. A retrieval index upd

The Iranian state-sponsored threat actor known as Nimbus Manticore (aka Screening Serpens and UNC1549) has been attributed to a fresh campaign using lures impersonating organizations in the aviation and software sectors across the U.S., Europe, and the Middle East following the joint U.S.-Israeli military campaign against the country in late February 2026. The activity, besides embracingView the full article

Patching practices are coming under intense pressure of late, as time-to-exploit windows accelerate — a new reality likely to worsen as AI assistance in attack chains rises. Now cyber defenders have another cause for flaw alarm: Vulnerability exploitation has significantly pulled away from stolen credentials as the most common entry point in security breaches, according to the latest edition of Verizon’s annual Data Breach Investigations Report (DBIR). Verizon researchers found that expl

A now-patched high-severity security flaw affecting Digital Knowledge KnowledgeDeliver, a Learning Management System (LMS) popular in Japan, was exploited as a zero-day to deliver the Godzilla web shell and ultimately facilitate the deployment of Cobalt Strike Beacon. The vulnerability, tracked as CVE-2026-5426 (CVSS score: 7.5), stems from the use of hard-coded ASP.NET machine keys, leading toView the full article

Cybersecurity experts are warning enterprise admins about an increasing number of phishing campaigns aimed at stealing Microsoft 365 (M365) access tokens to bypass multifactor authentication login protection. Phishing kits aimed at capturing M365 tokens aren’t new; some reports say these kits have been around since 2021. One of the latest is EvilTokens, which researchers at Sekoia say has been circulating since February. And earlier this month, Microsoft also issued a warning about other adv

Anthropic says it and upwards of 50 partners involved in Project Glasswing have uncovered an estimated 10,000 critical or high-severity vulnerabilities in their software offerings. The company launched the cybersecurity initiative, which is built around Claude Mythos Preview, in April, stating that its launch partners would use it as part of their defensive security work. Anthropic said it created Project Glasswing when capabilities in its new frontier model “revealed a stark fact: AI mo
