What is A1Lock ransomware? And how does it work?
A1Lock ransomware is a new variant of the Globe Imposter ransomware. This malware is a file-encrypting threat that functions as an extortion tool that demands ransom money in exchange for the recovery of the encrypted files. If your computer is infected with this virus, it connects to a Command and Control (C&C) server and starts to execute its attack. It then starts to scan your computer for files to target. It may target audios, videos, images, documents, databases and other important files. After finding the files, it will append the .707 file extension using a combination of AES and RSA ciphers to make all the files inaccessible. Once the encryption process is completed, it opens an html file named RECOVER-FILES.html that contains the message below:
“Your files are Encrypted!
For data recovery needs decryptor.
If you want to buy a decryptor, click the link:

How does A1Lock ransomware spread online?
Most of the variants of the Globe Imposter ransomware, including A1Lock, are distributed using malicious spam email campaigns where they attach the infected file and send them to a number of users, which is why you have to be careful when opening emails sent out by strangers. The infected attachment usually is contained in a document file. Most users tend to open documents thinking that it’s harmless when in fact, it is macro-enabled. When a document is macro-enabled, it can connect to a malicious domain and download the ransomware from it. Thus, your system will be infiltrated in no time. To prevent such attacks, it would be better if you check the sender first before opening or downloading any attachments. Or better yet avoid any suspicious-looking emails and delete them right away.
