What is BlackHeart ransomware? And how does it carry out its attack?

BlackHeart ransomware is a new crypto-malware discovered at the end of April 2018. This new crypto-malware is also known as BlackRouter ransomware. It spreads as malicious files named “SF.exe”, “TR.exe” or “BLACKROUTER.exe”. Based on the analysis done on this threat, it is proven that all of the aforementioned files carry the malicious payload of BlackHeart ransomware. Moreover, its source code also showed that this file-encrypting malware is a variant of the recently released Spartacus ransomware.

Such modifications could also result in the inability to start some software in the system or some Windows functions – needless to say, the computer’s overall performance will be greatly affected. After that, BlackHeart ransomware will begin to encrypt files. Just like Spartacus ransomware, it also targets files with these extensions:
Following data encryption, BlackHeart ransomware marks the encrypted files with either .BlackRouter or .pay2me file extensions and drops a file named “ReadME-BLackHeart.txt” that contains the following message:
“All your data has been locked us. You want to return? Contact to:
[email protected] Your Personal key:
In addition, this crypto-malware also institutes a lock-screen instance that contains this message:
