What is .Aes_ni_0day file extension virus?

.Aes_ni_0day file extension virus shows up as a new version of AES-NI ransomware

.Aes_ni_0day file extension virus is a new variant of AES-NI ransomware. It’s a “special” version of the virus which is called NSA EXPLOIT EDITION. However, it behaves similarly like the original virus. The purpose of the ransomware is to encrypt databases, documents, audio, video, image and other files using a random AES-256 encryption key, which is encrypted with an RSA-2048 public key. In the ransom note called “!!! READ THIS – IMPORTANT !!!.txt“ authors of the ransomware inform how victims can unlock files that have .Aes_ni_0day file extension. People need to contact cyber criminals via provided email addresses and wait for the instructions how to obtain a private RSA key to restore data. Though the scenario is quite obvious – cyber criminals will ask to transfer particular amount of Bitcoins. But instead of paying the ransom,[1] victims should focus on .Aes_ni_0day removal. Cyber criminals may not provide safe and working decryption key. Besides, they might ask for more money[2] and threaten to delete all the files. Ransomware is blackmailing program that must be terminated from the device using reputable security software, such as ReimageIntego.

Ransom note by .Aes_ni_0day file extension virus

.Aes_ni_0day file virus attacks computers using various distribution strategies. After infiltration, malicious files and components are installed in the %System Drive%, %AppData% or %Windows% directories. Then it modifies Windows Registry to run the virus on the system startup, insert malicious code into legitimate Windows process svchost.exe,[3] and deletes Shadow Volume Copies. However, malware has one quite unique feature. As soon as it gets on the device, it checks whether the computer belongs to users from the former Soviet Union block, or not. If so, malware deletes itself. Otherwise, after the attack, people need to remove .Aes_ni_0day malware themselves. Nevertheless, ransomware removal will not bring back access to the encrypted files; this step is crucial in order to protect your computer, data and personal information from other cyber threats. Once the virus is wiped out from the system, you can recover your files from backups or try alternative recovery methods.

Distribution methods of the ransomware

.Aes_ni_0day file extension virus might infiltrate computers using malicious email attachments, exploit kits, drive-by downloads, and many other methods. However, just like many other file-encrypting viruses, this one is also mostly distributed via emails. Crooks crafted numerous email examples where they inform about various issues and necessity to open an attached file. This file looks like safe Microsoft Office or PDF document;[4] however, they might be obfuscated VBS script, JavaScript or executable files. Thus, once users click on the malicious attachment, .Aes_ni_0day ransomware might sneak inside the computer and starts its damaging tasks. Moreover, this crypto-malware might pretend to be a legitimate software, crucial updates and any other important program or file that you can download from various online sources, such as Torrents, P2P Networks or file-sharing domains. Also, this cyber infection can use flaws in computer’s security and launch the attack with the help of exploit kit. Current rumours suspect that malware might be using Shadow Brokers’ exploits.[5]

Instructions for .Aes_ni_0day removal

In order to remove .Aes_ni_0day file extension virus from the device, you need to obtain reputable malware removal program.

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
