On December 7, 2021, Google announced it had sued two Russian men allegedly responsible for operating the Glupteba botnet, a global malware menace that has infected millions of computers over the past decade. That same day, AWM Proxy — a 14-year-old anonymity service that rents hacked PCs to cybercriminals — suddenly went offline. Security experts had long seen a link between Glupteba and AWM Proxy, but new research shows AWM Proxy’s founder is one of the men being sued by Google.
Security experts in Poland on Thursday quietly seized domains used to control the “Virut” botnet, a huge army of hacked PCs that is custom-built to be rented out to cybercriminals.
New research suggests that the majority of personal computers infected with malicious software may have arrived at that state thanks to a bustling underground market that matches criminal gangs who pay for malware installs with enterprising hackers looking to sell access to compromised PCs.
Pay-per-install (PPI) services are advertised on shadowy underground Web forums. Clients submit their malware—a spambot, fake antivirus software, or password-stealing Trojan—to the PPI service, which in turn charges rates from $7 to $180 per thousand successful installations, depending on the requested geographic location of the desired victims.
