ORX Locker, the new Darknet Ransomware-as-a-service platform

Security experts at Sensecy have uncovered ORX-Locker, a Darknet Ransomware-as-a-service platform that could allow everyone to become a cyber criminal.

It is becoming even easier to become a cyber-criminal thanks to the model of sale known as malware-as-a-service that offers off-the-shelf malware for rent or sale. Recently malware authors started to offer also Ransomware-as-a-Service (RaaS), in August security experts at McAfee discovered in the Deep Web a ransomware-construction kit, dubbed Tox ransomware platform that allows easy to build malware in just 3 steps, implementing this model of sale.
Now experts at Sensecy are warning of a new RaaS platform dubbed titled ORX-Locker, it allows criminals to create their piece of malware to infect systems and request the payment of a fee to unlock the system.

In RaaS model, when victims decide to pay, the malware redirects them through a service provider that keeps a percent of the fee and forwards the rest to the criminal.

ORX implements a sophisticated AV evasion method and complex communication techniques, the researchers discovered that it uses universities and other platforms as control infrastructure.

The First Appearance for the ORX ransomware is dated August 25, 2015, when a user dubbed orxteam announced the availability of a new RaaS service in a post.
