How to remove AttackNew Ransomware and decrypt .attacknew1 files

What is AttackNew Ransomware

AttackNew Ransomware is a malicious software variant belonging to the MedusaLocker ransomware family, which aims to extort money from victims by encrypting files and demanding a ransom for their release. Upon executing this malware on a test system, it was observed that it appended an extension, such as .attacknew1, to the names of the encrypted files. This ransomware uses sophisticated cryptographic algorithms like RSA and AES, making decryption extremely challenging without the unique decryption keys that the attackers possess. After successful encryption, it generates a ransom note named how_to_back.html, which can typically be found on the victim’s desktop or within affected directories. This note informs victims that their company’s network has been compromised and that their files are encrypted, emphasizing that any attempt to decrypt the files without the attackers’ help will lead to data corruption.

Currently, there are no publicly available decryption tools that can decrypt files encrypted by AttackNew ransomware. Accordingly, victims are often unable to recover their files without contacting the cybercriminals. Despite this, it is strongly advised against paying the ransom, as there is no guarantee that the attackers will provide the necessary decryption keys even after receiving payment. A recommended course of action involves identifying the ransomware using services like ID Ransomware and exploring resources such as the No More Ransom Project, although these measures may not always be successful. Moreover, to mitigate the impact of such ransomware attacks, ensuring comprehensive and regular backups of essential data in multiple locations is crucial. This preventive measure can help restore files from backups even when the encrypted .attacknew1 files cannot be decrypted.

How AttackNew Ransomware infects computers

AttackNew Ransomware primarily infects computers through phishing and social engineering tactics. Cybercriminals often disguise malicious files as legitimate attachments or links in emails, social media posts, or direct messages. Once the user opens the deceptive file, the ransomware is executed, initiating the encryption of files on the system. Additionally, this malware can spread via compromised websites that host malicious scripts, drive-by downloads, and untrustworthy software updates. Users can inadvertently trigger the installation of AttackNew by downloading software from unofficial sources or using illegal software activation tools. Once the ransomware infiltrates the system, it not only encrypts files but may also attempt to propagate through network connections and connected external storage devices, amplifying its impact.
