It is important to stress that Locky will encrypt files on network shares even when they are not mapped to a local drive.
The unique ID and other information will also be embedded into the end of the encrypted file. So when test.jpg is encrypted it would be renamed to something like F67091F1D24A922B1A7FC27E19A9D9BC.locky. When Locky encrypts a file it will rename the file to the format. key, wallet.datįurthermore, Locky will skip any files where the full pathname and filename contain one of the following strings: tmp, winnt, Application Data, AppData, Program Files (x86), Program Files, temp, thumbs.db, $Recycle.Bin, System Volume Information, Boot, Windows When encrypting files it will use the AES encryption algorithm and only encrypt those files that match the following extensions. Locky will then scan all local drives and unmapped network shares for data files to encrypt. When Locky is started it will create and assign a unique 16 hexadecimal number to the victim and will look like F67091F1D24A922B. Locky encrypts your data and completely changes the filenames This executable is the Locky ransomware that when started will begin to encrypt the files on your computer. The file that is downloaded by the macro will be stored in the %Temp% folder and executed. An example of one of these emails can be seen below. The email message will contain a subject similar to ATTN: Invoice J-98223146 and a message such as "Please see the attached invoice (Microsoft Word Document) and remit payment according to the terms listed at the bottom of the invoice". Locky is currently being distributed via email that contains Word document attachments with malicious macros. For those who wish to discuss this ransomware or have questions, please feel free to post in our Locky Ransomware Support and Help Topic. Like CryptoWall, Locky also completely changes the filenames for encrypted files to make it more difficult to restore the right data.Īt this time, there is no known way to decrypt files encrypted by Locky. Encrypting data on unmapped network shares is trivial to code and the fact that we saw the recent DMA Locker with this feature and now in Locky, it is safe to say that it is going to become the norm.
It targets a large amount of file extensions and even more importantly, encrypts data on unmapped network shares.
Though the ransomware sounds like one named by my kids, there is nothing childish about it. A new ransomware has been discovered called Locky that encrypts your data using AES encryption and then demands.
