Supply Chain Attack
RubyGems temporarily turned off new signups after what its security partner called a major malicious attack — hundreds of packages, DDoS, spam, and exploits hitting at once. The halt is the response model defenders should remember.
Cyber Attacks
An Iranian state-sponsored APT spent early 2026 conducting espionage while wearing the Chaos ransomware brand as a costume. Rapid7 pulled back the curtain. The Microsoft Teams screen-sharing tradecraft is why IR triage needs updating.
Cyber Attacks
Foxconn confirmed a cyberattack on its North American factories. Nitrogen ransomware claims 8TB and 11M+ files including Apple, NVIDIA, Google, Intel, and Dell project documentation. Mount Pleasant AI server factory was offline for a week.
Critical Infrastructure
West Pharmaceutical Services disclosed a disruptive ransomware attack via SEC Form 8-K on May 7, took global systems offline, and engaged Palo Alto Unit 42. The pharma-packaging CI adjacency just became a documented sector risk.
Application Security
TeamPCP's Mini Shai-Hulud worm hit 170+ packages May 11, including TanStack, Mistral AI, and Guardrails AI. First npm worm to ship valid SLSA Build Level 3 provenance for malicious code.
shinyhunters
Instructure paid ShinyHunters on May 11 to delete 3.65TB from 8,809 schools. Congress opened an investigation the same day. The vendor-paid-ransom precedent for SaaS is now set.
Artificial Intelligence (AI)
Google Threat Intelligence Group disclosed the first publicly confirmed AI-generated zero-day exploit caught in the wild on May 11. The Python script bypassed 2FA on a popular open-source admin tool and was destined for mass exploitation before Google disrupted it.
Application Security
TeamPCP compromised the Checkmarx Jenkins AST Plugin on May 9, the third attack on Checkmarx in three months. The Dune-themed defacement reads "Checkmarx fails to rotate secrets again." Either secrets rotation was incomplete or TeamPCP retained access through an unremediated persistence mechanism.
Cyber Attacks
A breach of GFN.am, NVIDIA's authorized GeForce NOW partner in Armenia, exposed user data including roughly 6,000 customer payment cards. ShinyHunters claimed responsibility, but BleepingComputer and Cybernews assess the claimant as a likely impersonator.
Cyber Attacks
Elastic Security Labs disclosed TCLBANKER on May 7 — a Brazilian banking trojan that targets 59 banks via DLL sideloading against Logitech's AI Prompt Builder, deploys WPF overlays for credential theft, and includes worm modules that hijack victims' WhatsApp Web and Outlook to spread itself.
Application Security
HiddenLayer disclosed on May 7 that a malicious Hugging Face repository, Open-OSS/privacy-filter, typosquatted OpenAI's legitimate Privacy Filter release and shipped a Rust-based infostealer called Boxter. The repo briefly hit #1 on Hugging Face and reached 244,000 downloads before takedown.
Policy & Government
The Cybersecurity and Infrastructure Security Agency launched a new initiative on Tuesday, May 5, 2026, called CI Fortify that pushes critical infrastructure operators across all 16 federally-designated sectors to prepare for sustained operations during geopolitical conflict, including scenarios in which third-party connections become unreliable and adversaries gain partial access to
