Summary

InvisiMole is a modular spyware and information stealing trojan believed to have been operating since 2013.

Affected platforms

The following platforms are known to be affected:

Threat details

It is used in highly targeted campaigns, typically infecting less than a hundred devices per time, and as such it has only recently been identified and analysed by security researchers. At the time of publication it is unclear how InvisiMole is distributed, although there are unconfirmed reports indicating it is manually delivered to targeted systems. The small number of available samples of the malware - combined with the secrecy with which it has been created and deployed - make it difficult to accurately determine delivery mechanism.

InvisiMole is comprised of two modules, RC2FM and RC2CL, with both being capable of collecting user data. RC2FM, the smaller of the two modules, is able to record audio from a device's microphone, extract proxy browser settings and alter system files. The more advanced module, RC2CL, is able to:

  • execute files and commands
  • manipulate registry keys
  • disable security services
  • function as a proxy for command and control communications
  • record audio and video

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.
