What is OopsLocker ransomware? And how does it work?

OopsLocker ransomware is a crypto-threat which is a new variant of the recently discovered Oops ransomware. This ransomware employs a combination of two encryption algorithms: the AES and RSA 2048 cryptographies. The contents on your computer is encrypted with the customized AES cipher while the decryption key is encrypted with the RSA 2048 cipher which prevents cyber security researchers in coming up with a decryptor. After it infiltrates your computer, it executes a task to enable it to communicate to its Command and Control server. From there, the ransomware sends particular information about the infected computer to the remote C&C server. The information sent out consists of the following:

  • Your computer’s protections and antivirus program
  • Your Windows operating system version
  • The keyboard setup
  • And your IP address

After OopsLocker ransomware settles in, it will start to scan the computer’s system to look for different file types which is over 40 file types including Microsoft Word documents, images, videos, mp3 files, databases, etc. It then starts the encryption process and appends the .oops file extension. Once it completed the encryption, it drops a file named EncryptedFiles.txt that contains the list of encrypted files and is placed on the folder named ProgramData in C that also have the EncryptedKey and KeyHash files. And then it opens an executable file, oops.exe containing the ransom notification that has the following text:

“Oops, all data in your computer has been encrypted.

Your encrypted key file is: C: \PrograrnData\oops\EncryptedKey

Your computer name is: [ACTIVE USER ACCOUNT NAME]

If you wanna decrypt all your data, please send 0.1 bitcoin to the address:

But BEFORE you pay me, you should send me an email with the ENCRYPTED KEY FILE as an attachment, YOUR COMPUTER NAME and BITCOIN ADDRESS you will pay with. So that i can know it’s your payment.

My email address is: only4you@protonmail. com

After i confirm the payment, i’ll send you an email with your KEY and COMPUTER NAME for decryption, you can input it below, and decrypt.”

The cyber criminals will threaten you that you should keep oops.exe running on your system if you are interested in paying the ransom to recover your files. They also require you to pay 0.1 Bitcoin which is approximately $233 according to the conversion rates at the time of writing this article. However, the crooks might extort more money than the amount stated.

How is OopsLocker ransomware distributed?

Just like the Oops ransomware, OopsLocker ransomware also spreads through spam emails. Its malicious file is disguised as a regular Microsoft Word file which contains macro-enabled commands used in carrying out its attack. So when you open this malicious document, you will receive a pop-up that alerts you to enable macros to view the content of the file. When you enable this, that’s where the ransomware starts its infiltration.

Take note that these emails may look like they’re from a well-known company or government organizations to make it believable and to attract your attention. There is no doubt that cyber criminals these days are getting cleverer in distributing their malicious files so you have to be cautious when you open files from unknown senders, well-known company or not.
