How to remove Numec Ransomware and decrypt .numec files

What is Numec Ransomware

Numec Ransomware is a malicious software designed to encrypt the files on a victim’s computer system, effectively locking them out of their own data. It appends the .numec extension to the filenames of encrypted files, turning a previously accessible document into an unusable format that requires decryption to be opened again. This ransomware employs sophisticated encryption algorithms that make it nearly impossible to decrypt the files without the specific decryption key that the attackers possess. When files are encrypted, they are typically stored in a folder named “EncryptedFiles” on the victim’s desktop. Furthermore, a ransom note, which is found under the filename GetFilesBack.txt, is dropped on the system, providing instructions on how to potentially regain access to the locked files. Unfortunately, decrypting these files is a challenge; no publicly available decryption tool can handle this particular ransomware variant. Victims are therefore faced with the dilemma of relying on potentially unsafe methods to recover their files.

Decrypting .numec files without paying the ransom or obtaining a decryption key from the attackers is extremely difficult. The ransom note instructs victims to download the Session messenger application and initiate a conversation with a specific account ID, sharing the EncryptedKey.enc file found on the desktop. This suggests that attackers use secure communication channels to negotiate the recovery of files, a method which further complicates any efforts to intercept or replicate the decryption process. The strong encryption used by Numec ransomware leaves potential victims dependent on having maintained recent and isolated data backups for recovery, as there are no faults in the encryption process that have been publicly discovered or exploit by third-party developers to create decryption tools. It's essential for users to adhere to preventative measures to avoid infection, like maintaining up-to-date systems, avoiding suspicious downloads, and regularly backing up data to minimize such dire impacts.

How Numec Ransomware infects computers

Numec Ransomware infiltrates computers through various deceptive methods commonly used by cybercriminals. One primary avenue is phishing emails, where unsuspecting users receive messages purporting to be from legitimate sources, containing malicious attachments or links. Once opened or clicked, these attachments or links download and execute the ransomware on the victim’s computer. Additionally, Numec can spread through compromised websites and malicious advertisements, which exploit vulnerabilities in browsers or plugins to deliver the ransomware payload. It is also often embedded in pirated software and distributed across peer-to-peer networks, tricking users into downloading and running the infected files. Furthermore, Numec may leverage software vulnerabilities to silently install itself, which underscores the importance of keeping systems and applications up to date with the latest security patches.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Numec Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
