In addition, malware like Crackonosh may also be disseminated through other means, such as phishing e-mail spam letters, trojans, deceptive third-party downloads, pirated/cracked downloads, fake software cracking tools, fake software updates/installers, backdoors, keyloggers, botnets, system exploits, and other channels as well. Though, it is also possible that Crackonosh occupies other installers of pirated games and programs to distribute itself. Thus, if any of these symptoms are present, make sure to read our guide below and eliminate the potential crypto-mining trojan from your computer.Īccording to available research, the Crackonosh trojan has been spread via installers of pirated games like Call of Cthulhu, Euro Truck Simulator 2, Fallout 4 GOTY, Far Cry 5, Grand Theft Auto V, Jurassic World Evolution, NBA 2K19, Pro Evolution Soccer 2018, The Sims 4, The Sims 4 Seasons, and We Happy Few. The main symptoms that should attract your attention and lead you to suspect something is wrong with your system are usually slower and laggy PC performance, increased CPU/GPU/RAM usage, overheating, unexpected crashes, and other related issues. In addition, Crackonosh may also halt Windows Update services and substitute the Windows Security icon with a fake green system tray icon. As a result, some infected systems may display error messages indicating issues with the aforementioned files. To conceal its presence, it erases system log files, serviceinstaller.msi files, and maintenance.vbs files.

This way, the trojan deactivates Windows Update and Windows Defender and is even able to uninstall third-party antivirus programs (e.g., Avast, Bitdefender, Kaspersky, McAfee, and Norton) in order to reduce the chance of getting detected and blocked. A couple of words on how the trojan does its malicious job: After the installer of cracked software is launched, it places an installer and script onto the targeted system, which then changes the Windows Registry settings to turn off hibernation mode and activate Crackonosh in Safe Mode at the next system start-up. As of now, statistics show that this miner has helped cybercriminals mine the amount of Monero worth roughly two million dollars. Upon successful installation, its purpose is to inject the XMRIG miner and start mining Monero cryptocurrency for the threat actors. Crackonosh is the name of a trojan stealthily distributed inside cracked software installers.
