SynAck ransomware to brute-force victims, mark files with random characters

SynAck (aka Syn Ack) ransom campaign is deploying at a significant pace. However, the plague had not accelerated its propagation rate until after the second week of September 2017. Over this period, hundreds of the users have submitted their samples for expert’s revision. They received the same feedback. It was SynAck ransomware that hacked their devices.
First reports on the threat detection date back to the beginning of August 2017. In total, at least three distinct specimens of the trojan circulate in the wild.

Those ransom notes dropped by SynAck ransomware provide two means of communication. The user will see a plain email-address like or, as well as BitMessage ID like BM-2cStoatQC4mDNWDHAoo2C1nYZJXhDsjCLj. The notification invites to contact the email address.

The infection is a ransomware-as-a-service. That implies it is available to multiple threat actors and is adjustable, including the ransom amount and propagation routines. A typical sum claimed by the crooks is slightly above USD 2,000. Of course, as bitcoin is an extremely fluctuating currency; this amount is a far cry from any stability.
To propagate the infection, the crooks often use a direct invasion. That is, they establish a remote control over the system and manually complete the SynAck ransomware installation. An installed instance of the infection scans the memory and discards only essential system and certain program file formats. This measure enables the system to survive with active Internet connection. Obviously, in doing so the crooks only aim at collecting the payment from the victims as soon as possible.
The files encrypted by the ransomware undergo typical name modification. They receive extra extension, which is a random set of 10 characters.
