Cybersecurity company Kaspersky Lab has reported that its researchers have uncovered a global forum where cybercriminals can buy and sell access to compromised servers for as little as US$6 each. The xDedic marketplace, which appears to be run by a Russian-speaking group, Kaspersky Lab said in a press release on Wednesday, currently lists 70,624 hacked remote desktop protocol (RDP) servers for sale from 416 unique sellers in 173 affected countries.
