Understanding the AttackNew Ransomware

AttackNew is a potent ransomware strain belonging to the MedusaLocker family, notorious for targeting large organizations through its double-extortion tactics. Once it infects a system, it encrypts the files, appending a distinct ".attacknew1" extension to each filename. For example, "1.jpg" becomes "1.jpg.attacknew1," and "2.png" turns into "2.png.attacknew1." The specific number in the extension may vary depending on the AttackNew variant.

Along with the encryption, AttackNew leaves behind a ransom note named "how_to_back.html." This note outlines the grim reality of the situation, stating that the network has been compromised and the files are locked using RSA and AES cryptographic algorithms. Victims are warned not to tamper with the files or use third-party tools, as these actions could render the files permanently inaccessible. Moreover, the note reveals that sensitive data has been exfiltrated, threatening that it will be leaked or sold if the ransom demands are not met within 72 hours. To show their "good faith," the attackers allow the victims to decrypt three non-essential files for free.

The Reality of AttackNew Ransomware

It's important to understand that once ransomware like AttackNew encrypts files, decryption without the attackers' keys is nearly impossible. Unfortunately, even paying the ransom does not guarantee that the cybercriminals will provide the necessary decryption keys or software. Paying also fuels further criminal activity, making it a choice that security experts strongly advise against.

The AttackNew Ransomware note reads like the following:

YOUR PERSONAL ID:

/!\ YOUR COMPANY NETWORK HAS BEEN PENETRATED /!\
All your important files have been encrypted!

Your files are safe! Only modified. (RSA+AES)

ANY ATTEMPT TO RESTORE YOUR FILES WITH THIRD-PARTY SOFTWARE

How to Remove AttackNew Ransomware

To prevent further encryption of files, it is crucial to remove the AttackNew ransomware from the affected system immediately. While removing the ransomware will stop it from causing more damage, it will not restore the encrypted files. The best solution for recovering these files is through backups. Therefore, it is always recommended to maintain backups in multiple, separate locations, such as remote servers or unplugged storage devices.

Preventing Ransomware Infections

The best defense against ransomware like AttackNew is a combination of vigilance and robust security practices. Since ransomware often spreads through phishing and social engineering techniques, it is essential to be cautious when handling emails and attachments from unknown or suspicious sources. Avoid downloading software or media from unverified websites and be wary of using third-party tools for software updates or activation, as these can be laced with malware.

Having a reliable, up-to-date antivirus program is another critical measure. Regular system scans and timely updates can help detect and eliminate threats before they cause significant damage.

If your system is already infected with AttackNew, using a reputable anti-malware tool to perform a comprehensive scan can help remove the ransomware from your system.

Conclusion

AttackNew ransomware is a dangerous threat, particularly for large organizations. While removing the malware is crucial, the best course of action is prevention. Regularly updating your security software, being cautious online, and maintaining secure backups are key strategies in safeguarding your data against such attacks.
