Code Analysis

You may be interested to know that the source code of the 2020 variant of HelloKitty ransomware was leaked on a cybercrime forum. As a result, researchers and analysts gained valuable insights into the ransomware’s inner workings. In this section, we will focus on the key elements of the code related to its propagation, encryption, and communication.

The HelloKitty ransomware is known for its aggressive propagation methods. The leaked source code reveals common techniques such as brute-forcing remote desktop protocol (RDP) connections and exploiting known vulnerabilities in network services. HelloKitty can also perform lateral movement within a compromised network, thus infecting multiple machines and increasing its overall impact.

Regarding encryption, the code demonstrates that HelloKitty employs a combination of symmetric and asymmetric algorithms. After infecting a machine, the ransomware generates a unique key for each file it encrypts, ensuring that data recovery is impossible without the corresponding decryption keys. To further complicate matters, these file-specific keys are encrypted with a public key, which can only be decrypted with the attacker’s private key. This means that even if you remove the ransomware from your system, your data remains inaccessible without the attacker’s help.

HelloKitty’s communication mechanism is another crucial aspect of this ransomware operation. The code uses a command and control (C2) server to receive instructions and updates from the attacker and send encryption keys and ransom details back to the attacker. By maintaining constant communication with the C2 server, the malware ensures that it remains up to date and can adapt its behavior based on the attacker’s directives.

The leaked HelloKitty ransomware source code provides valuable insights into the malware’s propagation, encryption, and communication methods.
