Rorschach
RORSCHACH ransomware is a type of malware that targets Windows operating systems and encrypts the victim’s files, demanding payment in exchange for the decryption key. Its technical details show that it is a complex piece of software, using various techniques to evade detection and ensure successful encryption.
RORSCHACH ransomware is typically distributed through phishing emails, exploit kits, or Remote Desktop Protocol (RDP) attacks. Once it gains access to the victim’s system, it will start encrypting files using a symmetric encryption algorithm, such as AES or RSA. It also uses a unique key for each victim, making decryption without the key impossible.
To evade detection, RORSCHACH ransomware uses a technique called process hollowing. This involves creating a legitimate process, then replacing its memory with malicious code. This allows the ransomware to run undetected, as it appears to be a legitimate process.
RORSCHACH ransomware also employs anti-analysis techniques to prevent researchers from reverse-engineering its code. It uses code obfuscation and anti-debugging techniques to make it more difficult for researchers to understand how it works.
Once encryption is complete, RORSCHACH ransomware leaves behind a ransom note in the form of an image of an inkblot, along with instructions on how to pay the ransom. It demands payment in cryptocurrency, typically Bitcoin, and threatens to delete the encryption key if payment is not made within a specified time.
RORSCHACH ransomware is a sophisticated piece of malware that uses various techniques to evade detection and ensure successful encryption of victims’ files. It is crucial to keep software up-to-date, backup important files, and be cautious when opening emails or downloading files from unknown sources to prevent such attacks from happening. If you suspect your computer has been infected, seek professional help immediately to minimize the damage.
