A hacker group called Librarian Ghouls is targeting Russians to secretly mine cryptocurrency. Kaspersky, a cybersecurity firm, believes these hackers might be hacktivists because of their use of legitimate third-party utilities. This technique is often used by similar groups elsewhere. By exploiting these methods, the hackers can secretly control computers and harness their power to generate cryptocurrencies, like Bitcoin, without the owners knowing. It's a digital-age heist targeting the tech-savvy public amidst geopolitical tensions. Be wary and update your security, folks!
