Infosecurity: Win-Spy is a commercial off-the-shelf (COTS) stealth monitoring tool. “Start Spying on any PC or Phone within the Next 5 minutes,” says its website. With such products generally available, why should hackers go to the trouble of developing their own RATs? Indeed, according to a FireEye analysis following an attempted intrusion on a US financial institution, they don’t.
The legitimate purpose of Win-Spy is to allow users to monitor their computers remotely while away, or to keep tabs on their young children. The less legitimate purpose allows parties to spy on spouses or partners. But an illegitimate purpose allows hackers to use a ready-made remote access trojan (RAT) for espionage and data theft purposes.
