Threat details

At the time of publication, it is unclear how ElectricFish is distributed, although it is likely to be delivered post-exploitation as part of HIDDEN COBRA's exfiltration processes.

Once installed, ElectricFish will initiate a connection with a command and control (C2) server using a bespoke protocol. It will then open the necessary ports to allow communication between the C2 server and other HIDDEN COBRA malware, such as TYPEFRAME and HOPLIGHT, on the affected device.

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.
