Issue: How to recover files encrypted by Ryuk ransomware?
Hello, I need help urgently! I recently opened an email attachment which I now understand was fake. It was presented as an Invoice, so I thought it is something important. Soon after I opened it, I saw a text file RyukReadMe.txt file generated on my desktop. When I opened it I realized that all my files are locked now. I do not have much experience with cyber infections, and I do not want to pay the ransom. Is that the only choice?! Please help me, I have several hundred photos that are important to me!
Ryuk ransomware is a relatively new cyberthreat that recently hit the headlines of various security networks, as it managed to extort nearly US$640,000 from victims. While it mainly targets organizations, it is well known that the malware also attacks regular users with somewhat decreased ransom size.
It is highly likely that most users get infected when they open suspicious attachments in the spam email or click on on a disguised hyperlink. That is why it is vital to make sure that the attachment or the link is legitimate before even trying to open it. If victims are more careful online, they would not have to worry how to recover files encrypted by Ryuk ransomware in the first place.
However, many users neglect security procedures, whether it is due to lack of the information or laziness. While general users are most likely to be infected via phishing emails, organizations are highly likely to be affected using brute force targeted attacks.
A detailed guide on how to recover files encrypted by Ryuk ransomware
Before the malware starts to encrypt data, it shuts down several services and processes that are running on Windows machines. Additionally, it stops several anti-malware programs from the operation and attempts to delete Shadow Volume Copies. Then Ryuk ransomware scans the device in order to look for files to encode. It uses a combination RSA-4096 and AES-256 encryption algorithms to lock up data and then drops ransom note RyukReadMe.txt and UNIQUE_ID_DO_NOT_REMOVE.txt, depending if the infected target is an organization or a regular user. Hackers demand a massive amount of 15 – 50 BTC ($100,428 – $334,763) for file release.
Researchers speculate that the malware was most likely created by the infamous Lazarus hacker group that was responsible for Sony hack back in 2014, as well as the devastating WannaCry ransomware attacks. Thus, the virus is operated by high-profile hackers who are willing to extort thousands of dollars. Nevertheless, users should not contact criminals, as there is no guarantee that they will receive the decryptor. More importantly, victims who pay only fund hackers' illegal activities.
