With that in mind, I'm going to take a closer look at ransomware that encrypts your files and append the .ezz extension to them; an unpleasant type of malware that is definitely an inhabitant of the more viscous end of the malware scale.
What does Alpha Crypt do?
Well we're giving no prizes away for guessing and the clue is most definitely in the name here as ransomware has been designed to hijack, or kidnap your files or data and render them unusable. It then sends you a ransom note HELP_TO_SAVE_FILES.txt which demands payment for the release of the files. You will be paying for a code which purports to be the key to unlocking the encrypted data. However, take any promises to send you this code with a bucket load of salt. Many ransomware programmers simply take the money and run, which shouldn't come as any great surprise, considering the people we're dealing with here! Alpha Crypt can be no exception.
How does ransomware send you a ransom note?
A ransom letter in the malware world won't be carefully cut out letters from newspapers like in the films of our youth (depending on how old you are!) but will be sent via an email or displayed on your screen. Some ransom notes are pop-up windows, others, rather menacingly take over your entire screen. This ransomware simply drops multiple HELP_TO_SAVE_FILES.txt files in folders where at least one file was encrypted. It also changes desktop background to HELP_TO_SAVE_FILES.bmp which displays the same ransom note as in the text file.
And just to add to the panic that you're no doubt experiencing since finding your computer in lock down mode, ransom notes amp up the fear factor in order to get you to pay quickly by telling you that the code will be invalid and you'll never be able to retrieve your files if you don't pay by a certain date (usually within 3 days).
But hold on, as it gets worse. Some types of ransomware design the note to look as if it was sent by the FBI, CIA or other law enforcement or government agency. The note will explain, in no uncertain terms, that you are being investigated due to your habit of visiting suspicious websites or illegally downloading programs. Even if you KNOW you haven't been on any websites supporting terrorism or download explicit images, the worry is still there. Did you accidentally click a link that you didn't mean to? Did someone else use your computer? Does the FBI know about that episode of The Walking Dead that you downloaded last week?
So now what? Should you make the problem go away by paying the ransom? The answer is most emphatically no. Do not encourage these online scammers. If you have a recent backup, wipe your hard disk and reinstall your files. If you don't, try Shadow Explorer program or search your computer for previous versions of files. If you are lucky enough you may find files that were not encrypted and renamed to .ezz. You can also use TeslaCrypt Decryption Tool by Cisco. It might just work with Alpha Crypt as well. But before restoring your files, please remove the ransomware and related malware files from your computer. Otherwise, you will simply waste your time.
