PowerLocker Ransomware

PowerLocker is a newly identified ransomware strain that encrypts files using the robust AES-256 algorithm. It appends the “.PowerLocker” extension to encrypted files and drops a ransom note named “IMPORTANT.txt” demanding payment for decryption. Victims are warned against modifying encrypted files or using third-party recovery tools, as these actions may render files undecryptable.

In-Depth Analysis of PowerLocker Ransomware

How Did I Get Infected?

PowerLocker typically infiltrates systems through:

• Phishing Emails: Malicious attachments or links disguised as legitimate communications.
• Malicious Downloads: Fake software updates or cracked software from untrustworthy sources.
• Exploit Kits: Compromised websites exploiting browser or software vulnerabilities.

Once executed, PowerLocker encrypts files and appends the .PowerLocker extension. It also changes the desktop wallpaper and creates a ransom note named IMPORTANT.txt.

What Does It Do?

PowerLocker employs AES-256 encryption to lock files, making them inaccessible without a decryption key. The ransom note instructs victims to contact the attackers to negotiate payment for the decryption tool. It warns against using third-party recovery tools or modifying encrypted files, as these actions may prevent successful decryption.

Should You Be Worried?

Yes. PowerLocker poses a significant threat due to its strong encryption and the potential for permanent data loss. Paying the ransom does not guarantee file recovery and may encourage further criminal activity. It is crucial to remove the ransomware promptly and seek alternative data recovery methods.
