Infostealers are among the favorite hacking tools of cybercriminals around the world. This is because this malware type is usually very small in terms of size, which allows it to carry out silent operations that can be highly successful potentially. Infostealers may allow their operators to collect information from messaging applications, email clients, Web pages, etc. Normally, infostealers connect to their creators’ C&C (Command & Control) server and siphon all the collected data to straight to the attackers. The Khalesi malware belongs to the infostealer class, and it appears to be active in the wild.
Propagation And Persistence
The Khalesi infostealer is likely being propagated via several means of distribution such as malvertising campaigns, bogus application downloads, mass spam email campaigns, pirated media, and software, etc. The Khalesi infostealer operates very silently, and users who fall victim to this threat may remain oblivious of the fact that there is malware present on their systems. Upon compromising a host, the Khalesi infostealer would gain persistence by creating a Windows Scheduled Task. This would make sure that even if the users reboot their computers, the Khalesi infostealer will run as soon as the PC is switched on again. The data that the Khalesi infostealer gathers is stored in the %TEMP% folder promptly. The gathered data will then be exfiltrated to the attackers’ C&C server.
This infostealer is known to collect data from:
- Google Chrome.
- Mozilla Firefox.
- Internet Explorer.
- Chromium-based browsers.
To avoid their creation being dissected by malware analysts, the authors of the Khalesi infostealer have made sure the threat is able to detect whether it is being run in a sandbox environment. This is done by checking the host for any software that may be linked to malware debugging. If the test is positive, the Khalesi infostealer will halt the operation and cease all activity.
If you have fallen victim to the Khalesi infostealer, we would strongly advise you to download and install a reputable anti-malware solution that will aid you in removing this threat from your PC quick and safely.
