Microsoft has disclosed details of two campaigns in which threat actors are abusing third-party email delivery infrastructure to blast financial fraud scam messages and using passkey-themed social engineering to breach cloud environments. The first campaign, per the tech giant, involved sending over a million scam emails between August 3 and 5, 2026, by masquerading as chief executive officers

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added five security flaws impacting JFrog Artifactory, ConnectWise ScreenConnect, and MikroTik RouterOS to its Known Exploited Vulnerabilities (KEV) catalog, following reports of active exploitation in the wild. Details of the vulnerabilities are as follows - CVE-2026-42016 (CVSS score: 8.1) - An incorrect authorization

Over the past year, we watched a new class of alert appear in enterprise security operations centers and grow faster than anything else in the stream: alerts that were triggered by AI tools and agents. Not attacks against AI, but the ordinary, everyday footprint of an organization using it, from developers running coding agents and non-technical staff signing consumer AI tools into corporate

The "major malicious attack" that targeted RubyGems in May 2026 was the work of a swarm of OpenAI agents, according to a new report published by researchers Spencer Kitts, Thomas Larsen, and Sydney Von Arx. On May 12, Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, disclosed details of a coordinated cyber attack that targeted the package manager for the

GitLab has released patches to address multiple flaws, including a maximum-severity security vulnerability that has witnessed in-the-wild probes within hours of public disclosure. The vulnerability in question is CVE-2026-85706 (CVSS score: 10.0), a path traversal issue in the repository commits API that could allow an unauthenticated user to read arbitrary files from the GitLab server under

Anthropic on Thursday said it identified and disrupted industrial-scale illicit distillation attacks against Claude from seven labs based in China, including Alibaba, Moonshot, DeepSeek, Z.ai (aka Zhipu), and MiniMax. Knowledge distillation by itself is a legitimate training method. It refers to a machine learning technique where a large, powerful AI model assumes the role of a "teacher" to

Anthropic has warned that cybercriminals and state-sponsored hackers alike are using its Claude models for cyber attacks, weapons design, propaganda, and mass surveillance between December 2025 and August 2026. The threat actors, which the artificial intelligence (AI) company has branded Generative Threat Groups (GTGs), span state-sponsored groups, financially motivated criminals, commercial

Anthropic on Thursday revealed it disrupted a campaign mounted by a Russian state-sponsored threat actor that abused Claude for developing an AI-assisted workflow to get ahead of the detection curve. The operation has been attributed to a cyber espionage group it calls GTG-20006 (where "GTG" stands for Generative Threat Group), which aligns with broader reporting linking the cluster to Midnight

Security teams have become exceptionally talented at finding vulnerabilities. Now, it’s time to turn our attention to optimizing the process for determining which of those vulnerabilities actually create a path to compromise. A critical vulnerability may look alarming on a scanner report, but if it sits behind strong segmentation, identity controls, and other defenses that prevent an attacker

Attackers have chained two flaws in JFrog Artifactory, the repository that software build pipelines pull from, to take administrator control of self-hosted servers and plant backdoors, cloud security company Wiz said in a report. Wiz saw the attacks between August 15 and September 8. JFrog had fixed both flaws before then, so only servers that had not been updated were open to them.

A China-linked hacking group exploited a flaw in Sogou Input Method, one of the most widely used tools for typing Chinese characters on Windows, to install a backdoor on victims' computers, security company Gen Digital said in research published Thursday. The attack started with a crafted link and ended with the attacker able to do anything the logged-in user could do. Tencent, which owns

PaperCut on Thursday released a new security maintenance release that replaces all previously published emergency patches that were pushed to address two security flaws that have come under active exploitation. The software development company said PaperCut NG/MF versions 26.0.5, 25.0.13 and 24.1.10 are now available for customers to download. "These are Regular Maintenance Releases (MR) that

Cisco has revealed that three distinct threat clusters linked to ransomware and state-sponsored attacks have been exploiting two recently patched Secure Firewall Management Center (FMC) vulnerabilities. The attacks leverage CVE-2026-20079 (CVSS score: 10.0), an authentication bypass vulnerability in the web interface of FMC software that could allow an unauthenticated, remote attacker to bypass
