The “hidden tear” project has brought yet another ransomware. It is named Strictor and it is also known as BankAccountSummary ransomware which wants 500$ from infected users to get the files encrypted by it back at their disposal. The ransomware locks the data using a very strong AES-256 cipher which would take years and years to crack unless a flaw in its code has been found. Experts advise infected users to not pay the 500$ ransom amount in most circumstances because their files may not be decrypted and they help the cyber-criminals develop and spread the virus. Instead, it is recommended to remove the ransomware and try and restore the data using alternative methods such as the ones below while waiting for a decryption method to be released.

Strictor Ransomware – Distribution
To be successfully deployed across computers, the creators of Strictor may have used spam messages that could feature either malicious e-mail attachments or malicious URLs such as the example below:
But, they have also though out this bottleneck very well, realizing it is the most important part of the infection process. This is why they may have used file obfuscators to hide the malicious payload carrying file from Anti-Virus and Anti-Malware programs.
Researchers have also reported that a malicious executable file pretending to be a .PDF document has been reported to be widespread via spam messages carrying Strictor. The file has the following name:
- Bank_Account_Summary.pdf.exe
Strictor Ransomware In Detail
After being activated on your computer, Strictor may create malicious files in the following Windows folders:
After creating the files, researchers at https://id-ransomware.blogspot.bg have reported that the ransomware creates the following registry entries:
→ In the key:

After changing the settings of the user, the ransomware may also connect to its command and control server:
→ 202.181.194.227
After connecting to the server, the ransomware may send different information from the infected computer:
- Decryption Key.
- System Information.
- Anti-Virus Information.
The ransomware also uses an AES-256 cypher to encrypt most usable files without damaging Windows:

The encrypted files by Strictor contain the .locked file extension, for example:
→ Picture.jpg.locked
After encryption, the ransomware virus is reported to create the following file:
→ C:\Users\Name\Documents\WindowsUpdate.locked
The ransomware virus may also delete the shadow volume copies of the infected users by 
In addition to that, Strictor Ransomware has preventive measures, when the user stops the connection to the internet. The ransomware displays the following message if there is no active connection:
