The extension alone is usually not enough to identify the exact ransomware family with confidence, especially after so many years. I cannot safely tell you whether files with “.raldug” can be decrypted without more evidence.
What to do first
Do not delete the encrypted files.
Make copies of a few encrypted files and keep the originals untouched.
If you still have it, keep the ransom note, email, wallpaper change, or any file names created by the malware.
If the infected system is still powered on and connected, disconnect it from the network.
Best places to check for a decryptor
Use trusted ransomware identification and recovery resources:
That gives the best chance of identifying the ransomware family correctly.
Reality check
Because the attack happened 10 years ago, recovery depends on the specific ransomware strain:
Some old families now have free decryptors.
Some never received a public decryptor.
In some cases, backups, old cloud copies, or previous file versions are the only recovery path.
If you want help on MalwareTips
Post the following in the appropriate malware help section:
A sample ransom note
A screenshot of encrypted filenames
One harmless encrypted sample file, if allowed by forum rules
Whether you still have the original infected computer or only the encrypted files
That will let knowledgeable members analyze it more accurately.
Key takeaway
Do not assume the “.raldug” extension by itself is enough. The safest next step is to identify the ransomware through ID Ransomware or No More Ransom, then check whether a legitimate decryptor exists.
If your antivirus software detects the tool as malicious, it’s safe to allow FRST to run. It is a false-positive detection.
If English is not your primary language, right click on FRST.exe/FRST64.exe and rename to FRSTEnglish.exe/FRST64English.exe
Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.
Double-click the FRST icon to run the tool. When the tool opens click Yes to disclaimer.
Press Scan button and wait for a while.
The scanner will produced two logs on your Desktop: FRST.txt and Addition.txt.
Please attach the content of these two logs in your next reply.
