A new Android spyware called ClayRat is luring potential victims by posing as popular apps and services like WhatsApp, Google Photos, TikTok, and YouTube.
The malware is targeting Russian users through Telegram channels and malicious websites that appear legitimate. It can steal SMS meessages call logs, notifications, take pictures, and even make phone calls.
Malware researchers at mobile security company Zimperium say that they documented more than 600 samples and 50 distinct droppers over the past three months, indicating an active effort from the attacker to amplify the operation.

The ClayRat campaign, named after the malware’s command and control (C2) server, uses carefully crafted phishing portals and registered domains that closely mimic legitimate service pages.

To add legitimacy to these sites, the threat actors have added fake comments, inflated download counts, and used a bogus Play Store-like UX with step-by-step instructions on how to sideload APKs and bypass Android’s security warnings.
