CCleaner, which is software that fights infections in PCs, was previously infiltrated by attackers in 2017 and led to the compromise of 2.27 million people’s systems. The reality is that the loss of revenue due to incident response, ransomware attacks, and cryptocurrency theft from installing pirated software could be more than the cost of the actual Windows and Office licenses.Czech antivirus vendor Avast on Monday warned that hackers were able to access its internal network using a temporary VPN account.Īvast said that it believes that the intrusion, first detected on Sept. In summary, if you thought that KSMPico is a smart way to save on unnecessary licensing costs, the above illustrates why that's a bad idea.

Moreover, Cryptobot checks for the presence of "%APPDATA%\Ramson," and executes its self-deletion routine if the folder exists to prevent re-infection. KMSPico is commonly distributed through pirated software and cracks sites that wrap the tool in installers containing adware and malware.Īs you can see below, there are numerous sites created to distribute KMSPico, all claiming to be the official site. "In fact, we even experienced one ill-fated incident response engagement where our IR partner could not remediate one environment due to the organization not having a single valid Windows license in the environment." Tainted product activators "We've observed several IT departments using KMSPico instead of legitimate Microsoft licenses to activate systems," explained Red Canary intelligence analyst Tony Lambert. ![]() KMSPico is a popular Microsoft Windows and Office product activator that emulates a Windows Key Management Services (KMS) server to activate licenses fraudulently.Īccording to Red Canary, many IT departments using KMSPico instead of legitimate Microsoft software licenses are much bigger than one would expect. This activity has been spotted by researchers at Red Canary, who warn that pirating software to save on licensing costs isn't worth the risk. Threat actors are distributing altered KMSpico installers to infect Windows devices with malware that steals cryptocurrency wallets. ![]()
