An .rrcc file is a computer file that’s been encrypted by ransomware criminals. It’s a variant of the STOP/DJVU ransomware, and although a newer entrant into the ransomware game, it’s quickly rocketed to prominence.
An .rrcc file appends standard computer files with “.rrcc,” so a Word file called “list.docx” would be renamed “list.docx.rrcc” by the ransomware after a successful attack.
These files can’t be decrypted without the key, which is where the ransom comes in. The ransom note (included in the attack as a _readme.txt file, similar to all STOP/DJVU ransomware) demands $980 in payment to get the key. This ransomware, though, has a discount option—payment is $490 if done within 72 hours. The payments are demanded in Bitcoin. Here’s the full message:

One wonders whether discount cybercriminals are a good thing or a bad thing.
One important thing to note is that the large majority of those who suffer a ransomware attack lose at least some data. Keep that in mind when deciding whether to negotiate or not, and whether or not to pay the ransom.
The .rrcc ransomware can also delete Volume Shadow copies, making restore operations difficult if not impossible. In addition, it usually includes password-stealing Trojans on a system, leaving victims vulnerable to things like double—or triple—extortion attacks and continued compromise of user accounts.
There are several options available to detect and remove .rrcc files, including this one. As always, the best way to protect your organization is to educate users about social engineering attacks and various email and other phishing scams.
