Cyber Attacks
Hunt.io found that a threat actor called PCPJack hijacked about 230 AWS, Google Cloud and Azure servers into a covert SMTP relay network — quietly converting business servers into verified mail proxies synced to a downstream consumer every five minutes.
Supply Chain Attack
Three disclosures this cycle share one thesis: attackers borrowing the trust of legitimate channels. A Rust-written npm worm (IronWorm), a cryptominer slipped into Hola Browser, and a Magecart skimmer hosted inside Stripe each hide in traffic defenders are inclined to allow.
Malware
McAfee Labs says WeedHack, a free-to-start Minecraft malware-as-a-service, has infected over 116,000 systems since January via fake mods pushed on YouTube and through SEO poisoning — and some buyers are using its remote-access tools to spy on and harass other players.
Malware
Silent Push has named DriveSurge, a pay-per-install access broker that has quietly hijacked thousands of legitimate websites and routes their visitors — on both Windows and macOS — into ClickFix and fake-update malware lures using an off-the-shelf traffic distribution system.
Nation-State Cyber Threats
Seqrite Labs says the Pakistan-aligned group SideCopy likely ran Operation XENOFISCAL, a spear-phishing campaign that hit Afghanistan's Ministry of Finance and provincial finance offices with the open-source Xeno RAT, delivered through a Pashto-language ZIP-and-LNK lure.
Supply Chain Attack
A compromised Red Hat employee GitHub account pushed a new 'Miasma' build of the Mini Shai-Hulud worm into 32 Cloud Services npm packages. Red Hat says the code was internal-only and never reached customers; any pipeline that installed a poisoned version should rotate its secrets.
Malware
Unit 42 documented Operation FlutterBridge, a macOS malvertising campaign that uses hundreds of Google-verified ads to drop FlutterShell — a new backdoor built with Google's Flutter framework that adds shell execution, file manipulation and AI-summarization-based exfiltration to adware.
Artificial Intelligence (AI)
Sophos documented a threat actor using AI agents — including a Claude Opus 4.5 coordinator — to run a lab testing malware against Sophos, CrowdStrike and Microsoft Defender. Notably, the lab's own claims of rising evasion success were not borne out by Sophos's data.
Nation-State Cyber Threats
Seqrite Labs disclosed Operation Dragon Weave, a China-aligned cyber-espionage campaign delivering an AdaptixC2 agent against government, research, academic, technology, and financial-services targets in the Czech Republic and Taiwan via spear-phishing ZIPs.
Nation-State Cyber Threats
Sekoia documented an FSB-linked Gamaredon campaign whose GammaWorm hides fileless VBScript modules inside NTFS Alternate Data Streams to spy on Ukrainian government, military, and critical-infrastructure targets while leaving almost no trace on disk.
Supply Chain Attack
The npm package codexui-android, a remote web UI for OpenAI Codex with 29,000 weekly downloads, has been exfiltrating users' Codex authentication tokens to an attacker server for the past month. The package is still live on npm.
Supply Chain Attack
Microsoft Threat Intelligence has named a new npm supply-chain wave the Mini Shai-Hulud campaign. A single maintainer alias, vpmdhaj, published 14 typosquatted packages in four hours that harvest AWS, HashiCorp Vault, npm, and GitHub Actions secrets from CI/CD runners.
