What is Conti Ransomware and how does it infect my files?

RYUK, first discovered in August of 2018, has already wreaked havoc for multiple large corporations and medium companies. Conti surfaced in July 2020 with behavior and ransom notes eerily similar to RYUK, such as AES 256 bit military grade encryption combined with RSA 4096.

Similar to Ryuk, Conti ransomware is particularly threatening for corporations and organizations that operate large and complex network infrastructure. While it has similarities to Ryuk’s source code and modus operandi, Conti is smarter, quicker and faster in encrypting data while shutting down entire networks. The connection between Ryuk and Conti is further supported by the fact that Conti attacks are increasing as Ryuk attacks decline.

The AES 256/RSA 4096 encryption alongside 32 simultaneous encryption threads used to encrypt files at unsurpassed speeds is what makes this an extremely dangerous malware for medium to large sized organizations. This means that the Conti ransomware can encrypt an entire network much faster than most other existing strains of ransomware, making it more difficult to catch and stop before it disrupts operations.

  • Here are some signs of a CONTI attack:
  • You receive a file titled: CONTI_README.TXT telling you that your data is encrypted and demanding a payment, often in the millions of dollars.
  • File extensions change to an extension containing five alphabetical characters in uppercase, such as .CONTI

  •  
    Firewall logs show significant unusual traffic to and from the network. This is usually indicative of data exfiltration.
  •  
    As many as 146 Windows application all related to security, backup and database are immediately blocked, rendering your security SOP’s useless.
  •  
    Extremely slow and sluggish operation of computers on the network resulting from file encryption.
What should I do when my data has been encrypted by CONTI Ransomware?
Conti is a smarter, more sophisticated and more dangerous variant of Ryuk ransomware. Corporations often find themselves targeted by Conti attacks. Since the targets are usually larger corporations and organizations, the ransom payment demanded is also usually much higher than many other ransomware cases.
If and when you find your systems in the middle of the encryption process, we strongly recommend you turn off all the machines connected to your network to minimize data loss.
This can also help to contain the spread of virus to backups.

Don’t attempt to decrypt the files on your own. So far, there is no free or paid decryption tool for Conti ransomware, but there are scammers that will offer easy fixes. The only way to decrypt the files is by obtaining the decryption key from the attackers.

CONTI RANSOMWARE STATISTICS & FACTS
RANSOM AMOUNTS
Conti targets corporations and enterprises with a large IT infrastructure. As such, ransom payments are often much higher than other variants, often in line with Ryuk.
The average Conti ransom amount is somewhere between $100,000–$350,000. However, some attackers have even demanded as high as $800,000 to over $1 Million. When purchasing Bitcoin to pay a ransom, quick-buy methods include a fee of as much as 10%.
  • RYUK Ransomware average ransom in USD $
AVERAGE LENGTH OF CONTI INCIDENT
Since Conti attacks corporations, the average length of incident is longer than other ransomware. This is because of the manual communication with attackers through email, which adds a considerable delay in the response time and data recovery process.
Since this is an enterprise-level attack, the longer your systems and files are held hostage, the costlier it will be in terms of PR damage. Your goal should be to get your systems back to productive state as soon as possible. The best way to do this is to call in experts like BeforeCrypt, who have a vast knowledge of this ransomware. We can help you in getting your network back up running.

CASE OUTCOMES
There is a high chance to get a working Conti decryptor after paying the attackers. But there’s never a guarantee to get a working decryption key at all. Since this is a new variant surfacing in June 2020, we still need more data to confirm whether or not a working decryptor is provided by attackers.
  • Paid Decryption Successful
  • Paid Decryption Failed
COMMON ATTACK VECTORS
It is in most cases either Remote Desktop Protocol or email Phishing are the 2 leading attack vectors. Unfortunately, even enterprises fail to secure their open RDP ports.
Due to an increase in remote working, a lot of employees now work from home using remote desktop control, leaving the company’s network exposed to hackers and all sorts of cyber criminals. But it isn’t limited to Remote Desktop Protocol.
In fact, the most common methods of this ransomware distribution is email phishing.

There is almost always a * .txt or *.html file in every encrypted folder. The text file is usually named “CONTI_README.txt” or “CONTIREADME.html” and contains all the information information to contact the Conti attackers. It’s usually safe to open this file, just be sure the full file extension is *.txt or *.html.
