Welcome to this week’s edition of the Threat Source newsletter. Ask anybody in this industry what the work does to the health of the people who do it and you get one word back: burnout. It's a fine word, in and of itself. It’s easy to reach for, understandable to everyone… and it's the wrong one, most of the time. So, story time. Last year I gave an interview with the amazing Hazel Burton about VPNFilter, and my run-in with burnout. I was a manager during that time, and it took a toll on me and…
BlueMoon, a shared Chrome and Windows exploit kit, shows why “patch later” is becoming a dangerous gamble. Security updates are easy to put off. The browser still opens, Windows still works, and choosing to relaunch your browser or restart your computer later can feel harmless. But a newly documented exploit kit called “BlueMoon” shows how quickly patching delays can become dangerous. Proofpoint Researchers found four espionage groups using the same exploit chain against Chrome browsers running…
U.S. cybersecurity and intelligence agencies say that six Chinese AI companies conducted industrial-scale distillation attacks on American frontier AI models since at least late 2024. [...]
Executive summary China-based artificial intelligence (AI) companies are conducting systematic extraction of proprietary functionalities and capabilities of U.S. AI companies’ models through industrial-scale knowledge distillation campaigns that form the core—not merely a supplement—of their AI development strategy. While “distillation” is recognized as a legitimate and useful technique in AI research, China-based AI companies are engaging in aggressive, malicious, and targeted distillation…
OverviewA new Linux toolkit, identified by Rapid7 Labs, has been targeting organizations across South Korea’s automotive and media industries with minimal detection. The campaign made use of a HAProxy instance named “ted backdoor”, alongside trojanized versions of crond, agetty, atd, sshd, and polkitd. This previously undocumented framework enabled threat actors to execute remote commands on compromised servers, inject malicious scripts into web traffic, perform credential harvesting, and…

The researchers discovered Fire Ant's new tactic after finding an active GRE (Generic Routing Encapsulation) tunnel interface on a Cisco IOS XR router that could not be explained by a running configuration or commit history. [...]
Attackers typically try to pass off malware as legitimate applications or as potentially unwanted programs that users deliberately search for and download, such as cheats or cracks. They often rely on ad and affiliate networks to deliver their creations to victims’ devices. This post examines a less conventional case: a well-known backdoor distributed under the guise of adware. The attackers may have chosen this distribution method because the adware was signed by the developer. On top of that,…

Introduction Today, Google Threat Intelligence Group (GTIG) will begin rolling out a unified naming schema for tracking threat actors. This new naming taxonomy represents an effort to standardize tracking across platforms and public reporting. Why are we Adopting a Different Naming System? Historically, Mandiant and Google’s Threat Analysis Group (TAG) maintained distinct tracking…
In April, SentinelLABS’ Tom Hegel published an initial assessment of the first five weeks of the conflict. Three months later, the evidence supports refinement. Executive Summary The cyber risk remains quieter than the public narrative. It rests on persistent access, trusted administration, service-provider pathways, selective disruption, and personas that magnify technical effects. Iran-linked activity is not a single threat set. MOIS, the IRGC Intelligence Organization, the IRGC Cyber…
Elastic Security Labs found a new Contagious Interview campaign, tracked as REF9403, hiding malware inside SVG image files using steganography. To our knowledge, this specific infection chain has not been previously documented. We found it after the DPRK-aligned group targeted our own community Slack workspace with a fake job posting and a "coding challenge" project. Any user who ran the project ended up with a four-stage payload aligned with OTTERCOOKIE: a browser credential and crypto wallet…

For years, the cyber security industry tracked AI as a force multiplier: something that made existing attack techniques faster, cheaper, and more accessible. That framing was accurate. But the Annual AI Security Report 2026 from Check Point Research documents a transition that goes further. AI has crossed from assistant to operator. Where it once helped attackers prepare, it now runs the operation. Key observed findings AI has crossed from development aid to live attack operator. It now does…
Note: SysAid was not compromised, and no SysAid vulnerability was involved. The attacker had already gained access to the victim environment and abused a legitimate software-deployment feature to deploy malware onto another machine within it. Key Points Check Point Research (CPR) tracks ‘Cavern Manticore’ as an Iran-nexus threat actor operating against Israeli targets, with a focus on the government and IT sectors.
