What is Exolock ransomware? And how does it implement its attack?

Exolock ransomware is another crypto-malware Trojan that carries a typical ransomware attack – it encrypts the victim’s files and then demand ransom to decrypt them. Exolock arrives in the computer system using a malicious email attachment. Once it is opened, the ransomware is downloaded and installed on the compromised computer.
During its attack, Exolock appends the .exolocked file extension on each targeted data. It is currently unknown which type of cryptography Exolock ransomware uses. At the same time, it creates or modifies some old Registry entries in your system and injects malicious code into your legitimate system processes. Following data encryption, Exolock ransomware opens a program window that demands ransom and contains the following text:

On its ransom note, the authors of the crypto-malware informs their victims about the unpleasant situation they are now in and that the only way to get their files back is by paying the ransom. And to make them sound scarier and tough, they tell their victims that if they close the program windows or shut down their computer, all their files will be deleted. You should know better than to believe these crooks. Paying them won’t actually get you out of the mess you are in. In fact you might be in even bigger trouble as cyber crooks are known to ignore their victims once they got what they want. You can actually try a couple of alternative solutions to recover your files, unlike what these crooks claimed, there is still a way to recover your files without having to pay a single cent. This alternative method uses the shadow volume copies of the encrypted files to restore them. Manage your expectations though for this method is only effective if the Exolock haven’t deleted the shadow volume copies during the encryption process – as uncertain as it seems, it still worth a try as nothing.

How does Exolock ransomware spread its malicious infection?

As explained previously, Exolock arrives in your computer via malicious spam emails. This is a highly-favored distribution method by many ransomware developers and they often use a macro-enabled document as an attachment to the email. The macro-enabled document is responsible in dropping the ransomware in your system. Aside from that, Exolock ransomware can also infect your computer using exploit kits on compromised websites and fake downloads. That’s why you must always ensure that both your system and antivirus program are updated to increase your computer’s resistance against these kinds of attacks. And it would be wise of you stir clear of any suspicious emails no matter how interesting it seems.
