NULL FILE EXTENSION CYBERSECURITY AWARENESS
Michael Gillespie, a malware security researcher, discovered Null as a ransomware-type the virus. Once Null is infected, it encrypts files using AES256.
This malware adds the ” .null extension” to filenames during encryption (for example, ” Sample.jpg” gets renamed ” Sample.jpg.null“. After successful encryption, Null opens an open-ended window with five tabs. These tabs provide details about “What’s happened.”
The first tab (” What has happened to my computer“) provides information to victims and encourages them to purchase decryption software. The Encrypted Files tab simply lists the files that have been compromised. The third tab ( How can I recover my files?) explains how to get the decrypter.
The fourth tab (” Send bitcoins?“) is supposed to explain how to send payment. However, at the time we researched it, we found no relevant text. The fifth tab, What’s AES256? Provides details about the encryption algorithm.

As we have already mentioned, Null uses AES256, an asymmetric encryption algorithm. Each victim is assigned a unique key that can be used to encrypt/decrypt files. Cybercriminals have obtained this key from a remote server and are trying to sell it for 2.2 bitcoins, which is roughly equivalent to $10000.
This ransom is much larger than other similar viruses. It usually ranges between $500 and $1500 in bitcoins. Cybercriminals are known to ignore victims after they have received payments.
These people are not to be trusted. You should not pay the ransom, regardless of whether it is $500 or $5000. There is a high chance that you will be conned.
