Threat Behavior of Syrk Ransomware

Syrk Ransomware is another menacing member in the arsenal of the gigantic Ransomware Family. Created with strong financial motive, this file virus is proliferating at a fast pace via malvertising e-mail campaigns, software bundling, malware-laden websites & links.

It is known for intruding into Windows OS based systems without any manual help. It targets user’s sensitive data to later blackmail them & extort their hard-earned money.

Once installed, it searches the entire system for the targeted files such as images, videos, documents, texts etc. When found, it employs a highly-complex Encryption Algorithm to encrypt the files & adds .syrk extension as suffix to the filenames.

After the encryption, the files are instantly made inaccessible to the victims. A file named “mypresentation.ppt” might be renamed as “mypresentation.ppt.syrk” after the encryption.

Targeted Files _ Syrk

The files extensions that Syrk File Virus is capable of encrypting are mentioned below:

  • Document files (.docx, .doc, .odt, .rtf, .text, .pdf, .htm, .ppt)
  • Audio Files (.mp3, .aif, .iff, .m3u, .m4u, .mid, .mpa, .wma, .ra, .avi, .mov, .mp4)
  • Video Files (.3gp, .mpeg, .3g2, .asf, .asx, .flv, .mpg, .wmv, .vob)
  • Images (.jpg, .jpeg, .raw, .tif, .gif, .png)
  • Backup Files (.bck, .bckp, .tmp, .gho)
  • Shadow Volume Copies
  • Restore Points

Apart from encrypting the files, Syrk Crypto Virus disables the anti-virus programs & firewall security on the infected PC. It makes modifications in the boot options, this enabling the infection to start every time the system reboots.

It disables “Task manager”, thus preventing the victim from closing down the harmful activities of Syrk. Analysts have found that Syrk makes certain pernicious Windows Registry Changes that causes unexpected errors, data loss & severe PC performance & stability issues.

Insight into the Ransom Amount Demanded by Hackers

Following the successful encryption of files, Syrk replaces the PC’s wallpaper with a ransom-demanding pop-up, which is in text format. The ransom note file, “Readme_now.txt” contains details of the current situation of PC & instruction for the victims to get their data back.

The note suggests that the encrypted data cannot be restored without the intervention of the hackers. It prompts the victims to contact the hackers on their e-mail id: panda831@protonmail.com & send them the appointed ID.

To check the unique appointed data, the victims are required to click on “Show My ID” button given at the bottom of the pop-up window.

The hackers then send further instructions to make the payment to restore the encrypted data.

They threaten the users to pay a hefty ransom amount in order to restore the encrypted files. The price of the unique key & Syrk decrypter is, however, unknown. Failing to make the payment in the pre-defined time may lead to the permanent deletion of the files & data.

Fearing to lose their data, victims often pay ransom to the hackers. However, paying the ransom does not guarantee decryption of files. Hackers often stop responding after receiving the ransom. Many of the victims who paid the cyber-criminals got scammed. They did not get the promised Syrk Decryption tool & unique key.

Therefore, under no circumstances, a victim should pay the ransom. Instead of panicking, the victims should act smart & not let hackers extort their hard-earned money.
