Ransomware attacks increase in number and magnitude, and its ability to evade detection has improved over the years. Several new forms of ransomware have been discovered, and much of this new malware is developing new and more sophisticated encryption mechanisms.

We will examine some of the most advanced new forms of ransomware today and how they differ from their predecessors. We will also touch on new forms of ransomware that are not specifically composed of other cybercriminal software.

Ransomware Formulas

Decrypting Ransomware

As we will see in this section, the ransomware families of today have been engineered to handle their tasks in different ways. This means that the current ransomware variants and their encryption types all play by different rules. To be able to decrypt the files, you need to use the original method by the ransomware’s author. In addition to this, the digital tools used to encrypt the files are being compromised, and this is something to be aware of if you have used one of these tools for this purpose in the past.

Resistance To Cryptographic Techniques

Ransomware authors are constantly improving the level of resistance to these different forms of encryption techniques. This means that even if the underlying techniques used by the ransomware are being compromised, you can often still recover the data encrypted by the malware.

Adaptive Encryption

The most common type of ransomware is adaptive encryption. This type of encryption is capable of encrypting any file the malware author chooses, rather than just the files the user has chosen to encrypt. The goal is to create as many encryptions as possible. However, because this type of ransomware is distributed using social engineering attacks that require the victim to click on a link to download and run the ransomware, the attackers know what files the user is likely to encrypt. This makes it much harder for the victim to resist by having to decrypt all of their files and manually enter each encryption code.

In an adaptive infection, the files become encrypted at a specific moment in time. This allows the authors of the ransomware to use a randomly generated encryption key to encrypt the files even when they are not being used to transmit a data stream. The specific time that the files are encrypted is called the “time period.” Because the encryption keys are randomly generated, they may change over time. This is more likely to be a problem for the victims as they are likely to see a different and larger key over time.
