Blackmail Trojan
A Blackmail Trojan is a type of malware that locks you out of your files or computer until you pay money to the hacker. It encrypts your data so that you can’t get to it without a special key that the hacker has. Unlike worms or viruses, which can spread on their own, Trojans trick people into installing them, usually by pretending to be something useful. The main goal of Blackmail Trojans is to make you pay money by holding your data hostage.
To reduce the risk of a Blackmail Trojan attack, it’s important to take security measures like installing antivirus software, keeping regular data backups, and learning how to spot phishing scams. For more help, check out our penetration testing and digital forensics services.

Should I pay the ransom if my system is affected by an extortion trojan? Experts generally advise against paying the ransom. There is no guarantee that you will actually receive the key to decrypt your data after payment. The payment also promotes the criminal activities of attackers.

Recovering encrypted data can be difficult. If you have regularly backed up your data, you can use them to restore it.
