The researchers of ESET have discovered an unknown trojan malware family that spreads via malicious torrents and uses multiple methods to extract as much cryptocurrency as possible from its victims while remaining undetected.
ESET named the threat KryptoCibule and, according to its telemetry, the malware appears to be primarily targeting users in the Czech Republic and Slovakia.
This particular malware is a triple threat to cryptocurrencies. It uses theconditions of the victim to mine coins, attempts to infiltrate transactions by replacing wallet addresses in the clipboard, extracts files related to cryptocurrencies, while deploying multiple techniques to remain undetected. KryptoCibule makes extensive use of the Tor network and the BitTorrent protocol in its communication infrastructure.
ESET has detected several versions of KryptoCibule, allowing us to study its evolution from December 2018 to the present. Malware remains active, new possibilities were added during its lifetime and is under constant development.
Most of the victims are located in the Czech Republic and Slovakia, and this reflects the user base of the site where the infected torrents are located. Almost all the malicious torrents were available on uloz.to, a popular file sharing site in both countries. In addition, KryptoCibule specifically checks for the presence of ESET, Avast and AVG security products. ESET is headquartered in Slovakia and the rest is owned by Avast, which is headquartered in the Czech Republic.
