BrainLag Ransomware – How Does It Enter Your PC?
What Is the Purpose of BrainLag Ransomware
Ever since 2013, ransomware has been using the Bitcoin currency as a payment system. That started when the CryptoLocker ransomware utilized Bitcoin as a secondary payment method. The efficiency of this cryptographic virus was huge, and it was due several things. One of them was its rapid spread on a massive scale using an already existing botnet – GameOver Zeus. The payload file was placed as email attachments and targeted companies and businesses. The encryption was highly sophisticated – it used AES 256-bit algorithm to encrypt files with a specific extension, then a 2048-bit RSA key to encrypt the AES one. That key was sent to command-and-control servers, established on the Tor network. It demanded $300 as payment.
It is terrible that a Bitcoin payment service, like the one used by BrainLag hosted on a Tor network is virtually untraceable, but the worst part is that ransomware is now served on a daily basis and shows no signs of stopping. The good thing is that it inspired security specialists to enhance their security programs and develop anti-ransomware tools.

- Adobe Reader, PDF

- Microsoft Office files

Recover files encrypted by the BrainLag Ransomware.

Method 2: If you try to decrypt your files using third-party decryption tools. There are many antivirus providers who have decrypted multiple ransomware viruses the last couple of years and posted decryptors for them. Chances are if your ransomware virus uses the same encryption code used by a decryptable virus, you may get the files back. Jedoch, this is also not a guarantee, so you might want to try this method with copies of the original encrypted files, because if a third-party program tampers with their encrypted structure, they may be damaged permanently. Here are the vendors to look for:
Method 3: Using Data Recovery tools. This method is suggested by multiple experts in the field. It can be used to scan your hard drive’s sectors and hence scramble the encrypted files anew as if they were deleted.
