Last week’s WannaCry ransomware could be dwarfed by a new malware that effectively enslaves Windows machines into botnets to mine for Monero. The rogue cryptocurrency miner called Adylkuzz has been affecting hundreds and thousands of PCs worldwide, according to researchers at cybersecurity firm Proofpoint.
Adylkuzz does not encrypt and lockdown files to demand bitcoin ransoms. Instead, the stealthy malware brings monetary gains to attackers by discreetly mining Monero, a cryptocurrency with enhanced privacy features compared to Bitcoin. Most victims are unlikely to even know that their Windows computers are compromised. The only symptoms of an infection are sluggish PC and server performance and the loss of access to shared Windows drives.
