SethLocker Ransomware Leaves Filenames Untouched

SethLocker is a type of malware that uses ransomware tactics to encrypt data and demand a ransom for its decryption. Unlike other similar malware that renames encrypted files with an extension, SethLocker does not alter filenames.

Once the encryption process is complete, a ransom note named "HOW_DECRYPT_FILES.txt" is created, warning the victims that their files, including various document formats, have been encrypted. The message demands an unspecified amount for decryption and warns that refusing to pay may lead to the leakage of sensitive data. The note also warns against manual decryption, which can render files undecryptable.

Based on our experience in analyzing and researching ransomware infections, we have found that decryption without the involvement of cybercriminals is rarely possible. In most cases, victims do not receive the necessary keys/tools to decrypt their data, even after paying the ransom. Thus, we strongly advise against paying the ransom, as it supports this illegal activity, and data recovery is not guaranteed.

Removing SethLocker from the operating system can stop further encryptions, but it cannot restore the already compromised files. The only solution is to recover data from a backup if one was made beforehand and stored elsewhere.

How Can You Prevent Ransomware Like SethLocker from Infecting Your System?

Preventing ransomware infections like SethLocker is crucial to avoid losing sensitive data and paying ransoms. Here are some steps you can take to prevent ransomware infections:

• Keep your software up-to-date: Ensure that all the software on your system is updated with the latest security patches. Many ransomware attacks take advantage of known software vulnerabilities.
• Use robust antivirus software: Install and regularly update antivirus software that can detect and remove known ransomware strains. However, be aware that some ransomware can bypass antivirus software.
• Use strong passwords: Use complex and unique passwords for all your accounts, including your operating system, email, and online accounts.
• Be cautious of suspicious emails: Do not open emails or attachments from unknown or suspicious senders, and avoid clicking on links in emails. Ransomware attacks often use phishing emails to trick users into downloading malicious attachments or visiting compromised websites.
• Back up your data regularly: Regularly back up all your important data to a secure, offline location, such as an external hard drive or cloud storage.
• Use two-factor authentication: Use two-factor authentication whenever possible to add an extra layer of security to your accounts.
• Disable macros: Disable macros in your email client and office applications to prevent malicious code execution.
