According to Cointelegraph citing BleepingComputer reports, information theft and clipboard hijacking Trojan Qulab is spreading video via YouTube on the so-called free bitcoin fraud. According to the report, these videos describe a tool that guides users through the links in the video descriptions to get free bitcoin. The link will point to downloading the so-called tool, which is actually a Qulab Trojan. After downloading, the Trojan needs to be installed to deploy. In addition to trying to steal user information, Qulab will attempt to steal the cryptocurrency by scanning the string copied to the Windows clipboard, identifying the encrypted address and replacing it with the attacker's address.
