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. On the surface, they differ in the letters that they deliver to the victims by dropping RESTORE_INFO txt-files. At the background, the differences include much more essential details that enable the rogue too often to escape anti-malware measures.
RESTORE_INFO-[victim’s id].txt “decryption” instructions
Those ransom notes dropped by SynAck ransomware provide two means of communication. The user will see a plain email-address like firstname.lastname@example.org or email@example.com, as well as BitMessage ID like BM-2cStoatQC4mDNWDHAoo2C1nYZJXhDsjCLj. The notification invites to contact the email address. The BitMessage ID is reserved for the cases where you do not receive the answer by email.
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.

Automated cleanup to remove SynAck virus
Infection vector for ransomware typically features a trojan. The one in question definitely subscribes to that routine. The trojan drops its body into target computer and proceeds with disabling the detecting functionality of any security solution installed. The antivirus is thus unable to spot introduction of virus from the remote server.
The ransomware invasion is indicative of its dropper residing in the computer memory. It also hints at other invasions. The PC can hardly be considered properly protected due to the impacts of the above trojan.
Ultimate option implies a total formatting for any drives of your PC. That is not an option for many users, for it destroys all the data hosted by the machine. The best solution to pick would be in-depth system examination with a reliable security suite.
The trojan that has installed SynAck ransomware , unless removed, is to trigger its installation campaign as soon as a new strain of ransomware is available. Thereby, it is critical to kill it as soon as possible.
The technique successfully overcomes malicious software, including any ransoming threats. It deploys a reputable security suite that offers not a single chance for malicious components to avoid detection and extermination. The software is incredibly user-friendly and operates on a single-click basic.
It is good to note the removal of SynAck ransomware does not recover the data affected. However, the virus is subject to compulsory extermination or else is going to introduce related infections into the machine.
1. Click the button to download the stub installer and go through several setup dialogs. Once the tool is up and running, click Start Computer Scan
2. Wait until the cleaner checks the PC for SynAck ransomware malicious code. As soon as the scan is completed, the report will list all malware objects spotted in the system. Make sure the entries for detected infections are checked, and select the Fix Threats feature. This will result in malware removal and system remediation, so you should now be good to go.
Restore the encrypted files
SynAck encryption is a sophisticated data modification. There is no simple and single solution to cover all the cases. Transferring the ransom as demanded by the crooks is not the way either.Kindly apply the methods outlined below as they have been carefully developed to provide a recovery help for the most severe cases of encrypting assaults.
Data recovery with automatic software
Good news is that the virus actually deals with copies of the files. The originals have been deleted. The removed data still can be restored by virtue of such tools as Data Recovery Pro.
Shadow Volume Copies
As Windows creates backups at given periods of time, a victim is advised to address relevant restore points. Unfortunately, the method cannot apply unless the System Restore had been enabled prior to the invasion. Please also note the recovery returns files as saved before the time associated with the restore point addressed.
- Previous Versions dialog to target individual files
One can open Properties for any file. The menu has a tab called Previous Versions. It indicates versions of a file that have been backed up.
To make use of the feature, right-click an affected file and choose Properties in the drop-down list. Proceed with clicking the above-mentioned tab. You can opt between the Copy or Restore procedures, the former enabling to copy the item into the location specified by the user.
Backups and removing remaining traces of SynAck virus
Prevention is the best cure. If you stick to making regular reserve copies of your data and store those outside your operating system, the impacts by the ransomware are very limited. However, prior to copying the data from backups into the system hit by SynAck ransomware, make sure the removal of this virus has completed.
Your manual removal attempts may kill the ransomware in general. In most of the cases, some remnants manage to survive and are still capable of causing a significant damage. Please apply a reliable anti-malware scanner to detect and remove, if applicable, any remaining infections.
