Introduction This post is a first-hand experience of all the phishing attempts against me after my data was exposed in four of the recent Trezor-related breaches. All four of these breaches were of Trezor third-party vendors, not Trezor themselves. The post is written as a personal narrative…
72,000 CVEs are projected to be published in 2026, while the median time from vulnerability disclosure to in-the-wild weaponization has fallen to well under 24 hours. Those two figures capture a growing challenge for defenders: more vulnerabilities to manage and less time to respond. Marc and Corey…
TL;DR Euler Neto, a member of the WatchGuard Threat Lab, identified an active ClickFix and EtherHiding campaign targeting Windows users in Anglophone countries. WatchGuard telemetry observed activity affecting the United States, Canada, United Kingdom, Ireland, Australia, and New Zealand, with the…
TL;DR Cristóbal Tárraga García, a member of the WatchGuard Threat Lab, uncovered a malware loader targeting Portuguese-speaking users that uses an Ethereum smart contract to dynamically locate attacker infrastructure and distribute additional payloads. The multi-stage infection chain combines…
TL;DR Euler Neto, a member of the WatchGuard Threat Lab identified an active malware campaign using the ErrTraffic Malware-as-a-Service framework to distribute multiple threats through compromised WordPress websites, ClickFix social engineering, and EtherHiding. The campaign uses Polygon blockchain…
Artificial intelligence is no longer just helping cybersecurity teams analyze alerts, write code, or investigate threats. Increasingly capable AI models can now reason through cybersecurity problems, identify vulnerabilities, chain weaknesses together, and autonomously pursue an objective. That…
TL;DR: OpenAI models under evaluation reportedly escaped a restricted lab environment, exploited a zero-day vulnerability to gain internet access, and targeted Hugging Face while attempting to solve a cybersecurity benchmark. The incident highlights the growing risk of autonomous AI-driven attacks…
WatchGuard telemetry identified a campaign associated to TimbreStealer, which is known to target companies based in Mexico. This research, conducted by Euler Neto and Cristóbal Tárraga, describes behaviors similar to those observed in a previous campaign documented by Cisco Talos in 2024, which uses…
TL;DR: Iran-linked MuddyWater, also known as Seedworm, is using trusted software, DLL side-loading, and legitimate tools to quietly spy on high-value organizations across manufacturing, aviation, finance, education, government, and public sector environments. This campaign is not focused on…
The WatchGuard Attestation Team has uncovered an undocumented pivot framework written in Golang that opens a Smux-multiplexed SOCKS5-style pivot channel on each compromised host using one of two interchangeable transports: KCP-over-UDP with DTLS obfuscation or Noise-over-TCP with TLS obfuscation…
