What is Khonsari Ransomware?
Khonsari has various features that make it stand out. Some of them include:
- Small in size (12KB)
- The infection process is not so visible; you could have an infection without being aware
- It uses encryption algorithms for which there are not likely any recovery keys, unless you pay the ransom. For example, it implements XOR on the first 16 bytes of a file and rotates with every new file
- Files can also be encrypted across various locations in a directory
- It uses AES and RSA encryption algorithm to encrypt files and hardcoded passwords for decryption (C&C server acts as a random key generator)
- Just like other ransomware, it drops ransom notes in all directories that contain encrypted files
How Does Khonsari Ransomware Work?
Khonsari ransomware spreads through unpatched PCs and servers, malicious spam email campaigns, or unpatched firmware (like that found in firewalls). If by spam email, it includes an attachment that appears to be a legitimate document but is an executable file. Unpatched software can compromise your system without a user even clicking on anything.
Once an unpatched system is compromised, or you open malicious file, the ransomware will encrypt files on the servers and computer it can reach. Khonsari ransomware will spread to other networked computers on the same network. It does this by creating a copy of itself in every folder containing encrypted files. Then, it will encrypt the files on those computers using the same encryption algorithm. Finally, it will drop ransom notes in each folder demanding payment for decryption keys.
Our IT professionals can eject the Khonsari ransomware bad guys from your networks by implementing security measures from something called a containment list. That list entails implementing and updating firewall rules, software patching, end-point detection and response software, segmenting the LANs, and implementing email filters. A multi-layered defense strategy is needed to stop the threat actors from continuing to do damage with this ransomware variant.
Other measures are sometimes required to prevent infections by Khonsari ransomware, such as DPI (Deep packet inspection) and IDS (Intrusion Detection System) on the firewall at your network perimeter, along with EDR software to help detect an infection in its earliest stages before files are encrypted.
Remember, maintain timely software updates for all computers, servers, routers, and firewalls. Monitor file systems for changes and the overall performance of the network. Educate employees on safe email practices, such as not opening suspicious emails or attachments.
