It's completely devastating me. Yesterday (or was it Tuesday? I don't even remember) I was left speechless and shocked by this nasty thing. What really destroys me is that I've dowloaded anything in the last week, or read emails. I've always been very careful about my Web habits, so I can't just figure out how I got that.

However, I got infected just booting my PC as I normally do every morning. Windows performed a CHKDSK command, and after what seemed an eternity my system started with just no usual desktop image, but with the README.bmp instead. It took me quite some time to understand what was going on, but unfortunately in the meanwhile my files were encrypted. I did a deep scanning using the TendMicro HouseCall, with no result. Then I tried with Avast (which detected some adwares and the usual things), but not the real thing.

Then, reading this site, I heard about Malwarebytes, so as a last resort I downloaded it and performed a deep scan... that seemed to work.

It pointed out, among other things, a trojan.crypt located in a file called "rad93C3E.tmp.dll" in my Documents and Settings folder. I just quarantained it, being not so sure about what to do next. I was tempted to remove it, but I'm too scared about crashing something.

Obviously I don't want to pay these criminals. They have no right to hold me captive in my own house, let alone all my data. I just hope someone will find a way to resolve this awful problem.

 

Sorry for my long post, I'm just frustrated.

CrypMIC mimics CryptXXX in terms of entry point, ransom notes (README.TXT, README.HTML, README.BMP) and payment sites but it does not append an extension to encrypted files. CrypMic (like TeslaCrypt v4.0) is identified by unique hex patterns in the file header despite having no file extension.Unfortunately, I am not aware of any way to decrypt CrypMIC encrypted data without paying the ransom.

There is an ongoing discussion in this topic where you can ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion, this topic is closed.

Thanks
