Decrypting ransomware before was uncomplicated. Using the decryption tools cybersecurity companies developed, the ransomware encrypted files can be recovered. But hackers applying the cryptosystems most intelligence companies use, ransomware encrypted files have become almost undecryptable.
The cryptosystems are used by the intelligence companies such as NSA to protect their top secrets from getting stolen.
AES or Advanced Encryption Standard, divides the information into blocks. Each block consists of 128 bits, that goes through 10 rounds that is based on substitution before the final key is generated. All the 128 bits get encrypted, making it impossible to crack.
RSA or Rivest, Shamir, & Adleman, uses mathematical algorithm to cipher a message. It involves public and private keys. The user defines the two prime integers, then the key of the first message is raised to the power of the first number divided into the module. That’s how RSA works.
These advanced cryptosystems applied on Ransomware may warrant paying the ransom. However, if ransomware encrypted files on your computer, trying alternative solutions is better than paying the ransom. The cybersecurity experts never recommend paying up the ransom because not all hackers provides the decryption key. Only half of those who paid the ransom got their files back.
What alternative solutions can ransomware victims try?
Is a project collaborated by different Law enforcement and IT Security companies to help ransomware victims restore files and data without having to pay the ransom. Only a few people know about https://www.nomoreransom.org. The website contains the decryption keys for the following types of ransomware.
GANDCRAB (V1, V4 AND V5 VERSIONS)
Once the ransomware that encrypts your files is identified by the extension, you can then download the correct decryption key.
Ransomware data recovery software are tools used to recover files and data deleted by viruses. They allow upto 2 GB data recovery. Varieties of files such as PDF, doc, jpeg, mp4, mp3, and more can be recovered even after they’ve been deleted permanently. You can download ransomware data recovery software such as EaseUS, Disk Drill, or Mini Tool. Download the file and follow the prompts on screen to finish the installation. Once the software is installed, it will start decrypting ransomware encrypted files.
You may also restore files/ data from Windows backup.
That’s another way to restore file encrypted by ransomware.
You can also recover ransomware encrypted files or corrupted data through a system restore. However, the version of the file in the restore point will overwrite the existing version. If you wish to continue;
Check in the location of the file has been restored successfully.
Once the files and data are restored, keep your computer protected to prevent ransomware from infecting the computer again. Install an anti malware software with advanced ransomware protection. Ransomware is stealthy and can easily infect a vulnerable personal computer.
In an organization, security software with advanced endpoint protection is ideal. The endpoint devices can serve as a point of entry of malware and a small breach is enough for ransomware to hack the entire network. Protect the endpoint devices with security software with the best endpoint protection.
Comodo Advanced Endpoint Protection provides the best protection for the network and endpoint devices. It consists of multi-layered defenses against varieties of malware. It has Auto-Containment, a sandbox based technology based on Default Deny that contains untrusted files the moment they enter the computer. The virtual container uses multiple recognizers that are trained to detect behavioral patterns instantly.
Comodo Advanced Endpoint Protection also consists of a fileless malware defense system that monitors and guards the registry against modification. It is also responsible for protecting the keyboard and hard drive against direct access. With a packet filtering firewall that monitors the network traffic and data transmission, malicious activities are prevented.
Comodo Advanced Endpoint Protection has been protecting 85 million endpoint devices worldwide and has contained 1,000,000,000 files with no report of infection. Download Comodo Advanced Endpoint Protection now for complete ransomware protection.
