CERT Polska identified a sophisticated Android malware campaign delivered through infrastructure impersonating Booking.com. The infection chain begins with phishing emails directing victims through Google share redirects to a fake Booking Pulse update page hosted at booking.interaction.lat. The downloaded APK (com.pulsebookmanager.helper.apk) acts as a multi-stage dropper employing native library obfuscation and anti-analysis checks. The outer APK decrypts and installs a second-stage package (io.cifnzm.utility67pu) masquerading as Google Play Services, which in turn extracts and decrypts a hidden asset (FH.svg) using RC4-like encryption keyed with 'mLYQ'. The final payload is a full-featured Android RAT communicating with otptrade.world via dual WebSocket channels.
The RAT abuses Android accessibility services to achieve extensive capabilities including screen streaming, keylogging, HTML overlay injection, SMS interception, camera access, remote gesture injection, device manipulation, and SOCKS5 proxy tunneling. The malware implements robust persistence mechanisms including uninstall protection, service health monitoring, alarm-based persistence, WebSocket recovery logic, and permission-loss protection. The dropper employs multiple anti-analysis techniques including libjdwp.so detection in /proc/self/maps, native JNI-backed string decoding with per-character XOR obfuscation, and Frida/emulator checks. Installation telemetry is exfiltrated to aplication.digital/receiving/stats. CERT Polska could not confidently attribute this malware to a known family as of the analysis date.

Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the malware it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
