Cybersecurity researchers have disclosed details of a new campaign that uses WhatsApp as a distribution vector for a Windows banking trojan called Astaroth in attacks targeting Brazil. The campaign has been codenamed Boto Cor-de-Rosa by Acronis Threat Research Unit. "The malware retrieves the victim's WhatsApp contact list and automatically sends malicious messages to each contact to further

Security teams are still catching malware. The problem is what they're not catching. More attacks today don't arrive as files. They don't drop binaries. They don't trigger classic alerts. Instead, they run quietly through tools that already exist inside the environment — scripts, remote access, browsers, and developer workflows. That shift is creating a blind spot. Join us for a[...]

Cybersecurity researchers have discovered two new malicious extensions on the Chrome Web Store that are designed to exfiltrate OpenAI ChatGPT and DeepSeek conversations alongside browsing data to servers under the attackers' control.

The first ThreatsDay Bulletin of 2026 lands on a day that already feels symbolic — new year, new breaches, new tricks. If the past twelve months taught defenders anything, it’s that threat actors don’t pause for holidays or resolutions. They just evolve faster. This week’s round-up shows how subtle shifts in behavior, from code tweaks to job scams, are rewriting[...]

Trust Wallet on Tuesday revealed that the second iteration of the Shai-Hulud (aka Sha1-Hulud) supply chain outbreak in November 2025 was likely responsible for the hack of its Google Chrome extension, ultimately resulting in the theft of approximately $8.5 million in assets.
