Armageddon Ransomware is a ransomware that has attacked the digital world recently and continues to extort money from innocent people with less knowledge on computers. It is a highly risky infection which was first spotted by S!Ri (siri_urz), a twitter user. Upon its penetration into the System, it encrypts most of the files in the user’s computer system by using the RSA-2048 Encryption Algorithm. Though it does not change the file extensions still the data is encrypted and a pop-up message is displayed seeking the ransom amount to be paid.

For gaining the ransomware encryption, the victims have to buy a decryption key from the developers of that malware. The decryption key for every encryption is different. This makes it hard to decrypt every time it attacks. So, the only way to free your computer is to uninstall Armageddon ransomware.

 

Encryption Algorithm

It uses RSA-2048. This encryption algorithm is asymmetric, so, it is difficult to decrypt it. The algorithm has a tendency to generate two decryption keys; private and public. The keys are stored in a secured server. This server is controlled by the developers who make sure that the server is difficult to locate or hack. All this camouflage makes it easier for the developers to blackmail the victims.

 

Armageddon ransomware ransom note

 

The ransom is around EURO 100 that too has to be made in BTC (Bitcoins- a digital currency). Paying the ransom is not a solution as the victims might be scammed. The developers start ignoring victims after the ransom has been paid.

It is evident as of now, that the RSA cryptography can’t be decrypted by any tool. But, Don’t Worry! We are here to help you, to eliminate Armageddon ransomware.

 

Threat Summary

 

Name Armageddon
Type Malware
Category Ransomware, crypto-virus
Operating System Windows
Encryption Algorithm RSA-2048
Infection File encryption

 

Threat Behavior

Armageddon ransomware encryption resembles many other ransomware that prevailed in the past decade. Each of the ransomware is designed to encrypt the files of your system. This encryption is done using AES or RAS cryptography usually. So recovering the files is impossible. The means via which it usually enters your system can be spam mails, locker apps, third-party cracked versions of software and updates.

After penetrating your system it encrypts your files using RSA cryptography. This encryption bars the user from opening his/her files. This encryption can be unlocked only with the help of the developers. This can be deduced after reading the message that pops up on your window every time you try to open an encrypted file. The message also mentions a ransom amount of EURO 100 to be paid to the developers by way of BTC (Bitcoins).

 

 How did it infect your PC?

Distribution Techniques-

This type of encryption ransomware attacks the system as soon it gets a safe passage to your computer. This passage is the download and installations of third-party software, spam mails, fake software updates, malicious web-pages and many other sources. All these techniques exhibit same behavior somehow. By the moment you click on or download any of the infections means listed above, a process will run in the background. The background process involves the cryptographic encryptions that modify the set of programs and encrypt your system-files.
