Beware of Deceptive Websites Hosting SpyNote Malware
Cybersecurity researchers have identified a wave of deceptive websites mimicking Google Chrome's installation page on the Google Play Store to distribute the potent SpyNote malware. This Android Remote Access Trojan (RAT) is being used for surveillance, data exfiltration, and remote control, making it a serious threat to individuals and organizations alike.
