Summary

First observed in 2018, Glupteba is a combined information stealing and downloader trojan associated with the Operation Windigo advanced persistent threat.

Threat details

Early Glupteba campaigns used compromised Linux-based web servers to distribute the malware, however, later campaigns shifted to an unidentified adware-as-a-service platform for delivery. The most recent campaigns have now begun using an unnamed preliminary dropper delivered via malvertising to install Glupteba.

Once delivered, Glupteba will connect to a command and control server before attempting to extract account data, browser profiles and passwords using an additional key logging module. It will then enumerate the local network to discover any Internet-of-Things devices, installing a SOCKS proxy on any it finds. Glupteba is also able to install other payloads including cryptocurrency miners and ransomware tools.

Remediation steps

Type Step

To prevent and detect a trojan 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.
