Cisco Talos recently discovered a new campaign delivering the HawkEye Reborn keylogger and other malware that proves attackers are constantly creating new ways to avoid antivirus detection. In this campaign, the attackers built a complex loader to ensure antivirus systems to not detect the payload malware. Among these features is the infamous “Heaven’s Gate” technique — a trick that allows 32-bit malware running on 64-bit systems to hide API calls by switching to a 64-bit environment.
