Summary

Kasidet is a point-of-sale (PoS) trojan that is designed to steal user data, particularly from electronic payment cards like debit and credit cards. Kasidet targets terminals that process card payments as well as Firefox, Google Chrome and Internet Explorer.

Affected platforms

The following platforms are known to be affected:

Microsoft Windows

Microsoft Windows – all versions

Threat details

The information it gathers is sent to its command and control (C2) server, where it can be analysed by the attacker. Kasidet impersonates legitimate Microsoft applications, allowing it to bypass User Account Control (UAC) defence mechanisms. Kasidet then triggers a pop-up to get the user to run the Windows Management Instrumentation command line utility (wmic.exe), which will run the executable file for Kasidet. This will instantly scan the infected device’s memory for financial card data and steal passwords for Outlook, Foxmail and Thunderbird.

Threat updates

Date Update
17 Jun 2018

The Ammy remote administration tool has been compromised to deliver Kasidet. Users who download Ammy from the official website are instead infected with a malicious variant that installs Kasidet before hiding its presence on the 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, antivirus 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 and password reuse is discouraged.
  • Network, proxy and firewall logs should be monitored for suspicious activity.
  • User accounts accessed from infected machines should be reset on a clean computer
