Threat Summary Strictor Ransomware – Distribution Strictor Ransomware In Detail Strictor – Conclusion, Removal, and File Restoration

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.

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.
