Summary

AZORult is a banking and information stealing trojan associated with other malware such as Rammnit, Seamless and RiG.

Threat details

Previously, AZORult was distributed through other intermediary malware such as downloaders or exploit kits. Newer versions, however, are distributed directly using malicious attachments in spam emails. These attachments use a number of techniques including macros and Dynamic Data Exchange to deliver AZORult.

Once installed, AZORult will spawn a legitimate process before injecting itself within the hollowed process to prevent detection. It will then send system data to a command and control server before monitoring any installed internet browsers for banking and cookie information. Newer variants of AZORult will also attempt to obtain Bitcoin wallet addresses, FTP or XMPP credentials and desktop files.

Date Update
31 Jul 2018

AZORult has now been updated to version 3.2. The following capabilities have been added:

  • Collection of search histories from most major Internet browsers (excluding Microsoft Edge and Internet Explorer)
  • Theft of wallet credentials for the Electrum, Electrum-LTC, Ethereum, Exodus, Jaxx and Mist cryptocurrencies.
  • Support for system proxies.
  • A new loader module that functions using a number of conditional relationships, altering the files loaded depending on the conditions being met.

It also appears to be loading the Hermes ransomware as a secondary module, potential to mask its actions on an infected device.

Remediation advice

To prevent and detect a trojan infection, ensure that:

Remediation steps

Type Step
  • 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.
  • 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.
