Other security researchers have tracked these malware families under the names BazarLoader and BazarBackdoor or Team9. This document contains an in-line link to a URL hosting a malware payload. When clicked, these links download malware binaries with file names masquerading as document files. In recent campaigns, the malware payloads have been hosted on numerous URLs associated with one or more of these legitimate services. In addition to the use of common post-exploitation frameworks such as Cobalt Strike, Metasploit and EMPIRE, we have observed the use of other backdoors, including ANCHOR, that we also believe to be under control of the actors behind TrickBot. The attackers have employed Cobalt Strike payloads crafted to maintain persistence through reboot via a scheduled task on critical systems in victim environments. In addition to the use of common post-exploitation frameworks, lateral movement has also been achieved using WMIC commands and the Windows RDP and SMB protocols. The actors have used Cobalt Strike BEACON to exfiltrate data created through network reconnaissance activities as well as user files. Although it is a low fidelity indicator, ANCHOR activity may also sometimes be identified by searching for binaries within the C:\Windows\SysWOW64 directory that have a file name matching the following pattern: &lt;8 random lowercase chars&gt;.exe. Stacking or sorting on file creation timestamps in the C:\Windows\SysWOW64 directory may also help identify malicious files, as the directory should be mostly static
