Lethal Lock Ransomware Will Encrypt Your Files
During our analysis of new malware samples, we encountered a ransomware variant known as Lethal Lock. This ransomware encrypts files and adds its extension (".LethalLock") to their filenames. Additionally, Lethal Lock generates a ransom note ("SOLUTION_NOTE.txt") and alters the victim's desktop wallpaper.
For instance, files encrypted by Lethal Lock are renamed as follows: "1.jpg" becomes "1.jpg.LethalLock", "2.png" becomes "2.png.LethalLock", and so forth. The ransom note starts by acknowledging the breach of server security by "LETHAL LOCK," a cyber entity. It describes the encryption process as highly intricate and warns that recovering files without the decryption key is nearly impossible. It threatens permanent data loss and immediate action if the ransom is not paid within 72 hours.
Instructions for reaching customer support via Telegram (@lethallock) and transferring 25 bitcoins to obtain the decryption key are included.

How Can You Safeguard Your Data from Ransomware Attacks?
Protecting your data from ransomware attacks requires a multi-layered approach to security. Here are several strategies you can implement:
Regularly Back Up Your Data: Ensure you have regular backups of your important files stored in a secure location that is not directly accessible from your primary network or system. This way, if you fall victim to a ransomware attack, you can restore your files from backup without paying the ransom.
Keep Your Software Updated: Make sure all software on your systems, including operating systems, antivirus programs, and applications, is up to date with the latest security patches. Vulnerabilities in outdated software can be exploited by ransomware attackers.
Use Antivirus and Anti-Malware Software: Install reputable antivirus and anti-malware software on all your devices and keep them updated. These programs can help detect and block ransomware threats before they can cause harm.
Enable Email Filtering: Implement email filtering solutions to block suspicious emails and prevent them from reaching your inbox. This can help reduce the risk of falling victim to phishing attacks that distribute ransomware.
