News about the .Cl0p ransomware became known to us in several reports. According to the new information one of the hacking groups has started to release files of a company called EV CARGO Logistics due to the fact that they have not paid the requested fee in the designated time frame. Information about the file names has been posted online in several communities giving further details about the hijacked data:

The leaked sensitive information may include the following:
- Network Drive Passwords
- Client Information
- Financial Information
On a separate note another hacking group is offering a service called network security consulting for corporations — allegedly the hackers are offering penetration testing and other related actions. The price requested by them is $250K in Bitcoin (BTC).
.Cl0p Virus Files – Update February 2020
In February 2020 information about Cl0p ransomware infections became known to us — a Dutch university has allegedly paid the sum of 30 BTC to hackers following a public press release. This amount is about $220,000 and has been given to the hackers following a network-wide infection that took place around Christmas last year. The information was live streamed to the public and the staff explained how they were aware about the impact the virus had on their internal networks — and particularly the effect on the files of the staff and students.
The trouble with hackers began back in October when phishing emails were opened on workstations that were on the internal network of the university. Through the malicious code placed inside hackers were able to infect the internal systems. Further damage was done when they outdated server configurations which were exploited in order to acquire administrative privileges. Later on this access was used to deliver the Cl0p ransomware.
.Cl0p Files Virus – Update November 2019
The .Cl0p virus has seen a newer version which includes the ability to detect and bypass the Windows Defender security suite. The new CryptoMix variant can also overcome the Microsoft Security Essentials package (used in older versions of Microsoft Windows) and also the MalwareBytes anti-virus. This new release uses the same .clop extension and creates a ransom note that is called ClopReadMe.txt.
The analysis performed by the security researcher shows that anti-virus bypass is performed before the encryption phase is done. These services are disabled by reconfiguring the Windows Registry and removing the configuration settings of these processes:
- Behavior Monitoring
- Real-Time Protection
- Sample Uploading
- Tamper Protection
- Cloud Detection
- Anti-Spyware Detection
.Cl0p Files Virus – Update October 2019
The security analysis of the ongoing .Cl0p virus samples shows that the threat is being launched by a new hacking group and using a new distribution technique. It appears that the criminals this time are experienced enough as many samples have been detected. The .Cl0p virus is primarily being sent via infected documents — they can be spreadsheets, databases, text files and presentations. When they are opened a prompt will ask them to enable the built-in macros which will trigger the infection.
One of our sources states that it is possible that the attacks are being performed by the TA505 hacking collective. They are known for executing complex attacks against high-profile targets, specifically enterprise industries and government establishments.
.Cl0p Files Virus – Distribution Methods
Another possible mean of replication of the .Cl0p file ransomware is believed to be malicious macro code that may be inserted into documents. These documents may be sent to victims as a result of being embedded as e-mail attachments, where they may pretend to be invoices for purchases and several other types of seemingly important files, like:
- Invoices for online retail stores.
- Banking documents.
- Work-related documents.
Once the victim opens the document, it may ask him or her to “Enable Editing” by cicking on the button, similar to what the image below shows:
This triggers the malicious script, which may result in the unpacking of the malicious executable and running it automatically on the computer of the victim.
.Cl0p Ransomware – More Information
Once installed on the victim’s computer, the .Cl0p file ransomware is the type of virus that aims to infect computers and then extort the owner for money. The analysis of the virus so far detected several files, associated with Cl0p Ransomware:
File name: 3c8e60ce5ff0cb21be39d1176d1056f9ef9438fa.exe
File size 235.5 KB
File size:100.5 KB
Once .Cl0p file ransomware already infected a computer, the virus may drop it’s malicious executable directly on the desktop of the victim PC. Besides it, .Cl0p ransomware also drops it’s ransom note file, called Cl0pReadMe.txt. It looks like the following:
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.
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.
The final price depends on how fast you write to us.
Once the Cl0p ransomware virus has already compromised a given machine, it is reported in a VMRay analysis to interact with the following Windows system files:
The Cl0p ransomware virus may also extract the following information from victimised machines:
- System time.
- OS Type.
- Keyboard language.
In addition to this analysis of Cl0p Ransomware reports it to perform the following activities:
- Delays it’s own execution.
- Changes appearance of folders.
- Creates a lot of new files.
- Overwrites code in files.
The virus does not communicate over the web to cyber-criminal control servers and does not seem to delete any volume shadow copies of the machines it has infected.
Cl0p Ransomware – Encryption Process
The encryption of Cl0p ransomware is believed to be conducted with the aid of the RSA (Rivest-Shamir-Adleman) encryption algorithm. The ransomware virus may first scan for the file types it is set to encrypt. These files are usually only the usable files, of the following types:
- Virtual Drive.
Once the ransomware encrypts those files, it also renames them, making the file start to look unrecognisable:
