What is Clop ransomware? And how does it execute its attack?

Clop ransomware is a newly discovered file-encrypting malware that uses the .Clop extension. At the time of writing, it isn’t clear whether the encrypted files of this ransomware can be decrypted or not. The instant it infiltrates a computer, Clop ransomware will drop the following payload file:

SHA-256:d0cde86d47219e9c56b717f55dcdb01b0566344c13aa671613598cab427345b9

File name: 3c8e60ce5ff0cb21be39d1176d1056f9ef9438fa.exe

File size 235.5 KB

 This payload file is the one that establishes a connection to a remote Command and Control (C&C) server controlled by the cyber crooks behind Clop ransomware. After establishing connection, it downloads its malicious components and puts them into several folders in the computer. These malicious components are as follows:

  • SHA 256:3320f11728458d01eef62e10e48897ec1c2277c1fe1aa2d471a16b4dccfc1207

File name: unpacked.exe

File size: 100.5 KB

  • SHA-256:d0cde86d47219e9c56b717f55dcdb01b0566344c13aa671613598cab427345b9
  • File Name: tcpsov.exe

After dropping its malicious files, Clop ransomware will execute a series of modifications. It alters some registry keys and sub-keys in the Windows Registry such as the Run and RunOnce keys. It allows the crypto-virus to execute its attack automatically in every system boot. It also collects information which will be used to generate a unique ID and scans the system for presence of security applications, virtual hosts, sandbox environments, and antivirus programs.

Moreover, Clop ransomware is also reported to interact with the following Windows system files:

  • Kernel32.dll
  • Kernelbase.dll
  • User32.dll
  • Gdi32.dll
  • Shell32.dll
  • Shlwapi.dll
  • Crypt32.dl
  • Mpr.dll

After it completes modifying system settings, Clop ransomware encrypts its targeted files using the RSA 1024 cipher. It then adds the .Clop suffix to every encrypted file and opens a ransom note named “ClopReadMe.txt” which states:

“Your network has been penetrated.

All files on each host in the network have been encrypted with a strong algorithm.

Backups were either encrypted or deleted or backup disks were formatted.

Shadow copies also removed, so F8 or any other methods may damage encrypted data but not recover.

We exclusively have decryption software for your situation

No decryption software is available in the public.

DO NOT RESET OR SHUTDOWN – files may be damaged.

DO NOT RENAME OR MOVE the encrypted and readme files.

DO NOT DELETE readme files.

This may lead to the impossibility of recovery of the certain files.

Photorec, RannohDecryptor etc. repair tools are useless and can destroy your files irreversibly.

If you want to restore your files write to emails (contacts are at the bottom of the sheet) and attach 2-3 encrypted files

(Less than 5 Mb each, non-archived and your files should not contain valuable information

(Databases, backups, large excel sheets, etc.)).

You will receive decrypted samples and our conditions how to get the decoder.

Attention!!!

Your warranty – decrypted samples.

Do not rename encrypted files.

Do not try to decrypt your data using third party software.

We don`t need your files and your information.

But after 2 weeks all your files and keys will be deleted automatically.
