Summary

First observed in late 2019, PowerTrick is a PowerShell-based backdoor believed to have been created by the group operating TrickBot for use against high-value targets.

Affected platforms

The following platforms are known to be affected:

Microsoft Windows

  • Microsoft Windows - All versions

Threat details

PowerTrick is delivered after a system has been compromised, either by TrickBot itself or by a preliminary loader in a similar manner to the PowerShell Empire post-exploitation toolkit. An initial small staging module is first installed, which then attempts to collect system information and send it to a command and control (C2) server. If this information matches the group's target requirements, an instruction will be sent to the stager to download the primary PowerTrick module.

Once installed, PowerTrick will collect detailed information on both the system and users, before sending it to a separate C2 server. It will then attempt to install a number of other payloads including the TrickBot Anchor DNS tool and the more_eggs Java backdoor.

Remediation steps

Type Step

To prevent and detect an infection, ensure that:

  • A robust program of education and awareness training is delivered to users to ensure they don’t open attachments or follow links within unsolicited emails.
  • All operating systems, anti-virus and other security products are kept up-to-date.
  • Regular anti-virus and security scans are performed on your organisation’s estate.
  • All day-to-day computer activities such as email and internet are performed using non-administrative accounts.
  • Strong password policies are in place.
  • Network, proxy and firewall logs should be monitored for suspicious activity.
  • User accounts accessed from affected devices should be reset on a clean computer.
  • Your organisation adopts a holistic all-round approach to Cyber Security as advocated by the 10 Steps to Cyber Security.
