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

RYUK, first discovered in August of 2018 has already wreaked havoc across large corporations and medium sized companies. Conti, surfacing in July 2020 with patterns and ransomnotes eerily similar to RYUK’s characteristics such as AES 256 bit military grade encryption combined with RSA 4096.

Similar to Ryuk, Conti ransomware is increasingly a threat to corporations, and enterprises that operate large and complex network infrastructure. While it displays similarities with Ryuk source code and modus operandi, Conti is smarter, quicker and faster in encrypting data while rendering entire networks useless. It has also been observed that Conti attacks are skyrocketing at a time when Ryuk is slowly fading away.

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, wreaking havoc on day to day operations.

Here are some signs of a CONTI attack:
You receive a message in CONTI_README.TXT that your data is encrypted, demanding a payment often in millions of dollars.
File extensions change to an extension containing five alphabetical characters in uppercase such as, .CONTI
Firewall logs show significant traffic to and from the network in an abnormal fashion, typically indicative of data exfiltration.
As much as up to 146 Windows application all related to security, backup and database are immediately blocked, rendering your entire security SOP useless.
Since all files are encrypted, you may notice machines operating extremely slow and sluggish.

What should I do when my data has been encrypted by CONTI Ransomware?

A variant of RYUK, Conti is smarter, sophisticated and more dangerous than the original ransomware. Corporations often find themselves targeted by Conti attacks. Since the targets are large enterprises and corporations, the demand for ransom payment is also much higher than most ransomware cases.

We strongly recommend you turn off all the systems on your network to avoid catastrophic loss of data, if and when you find your systems in the middle of the encryption process.

This helps in containing the spread of virus to the backup drives.

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.

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.
