AES_KEY_GEN_ASSIST ransomware / virus (Improved Instructions)
AES_KEY_GEN_ASSIST virus Removal Guide
What is AES_KEY_GEN_ASSIST ransomware virus?
How destructive is AES_KEY_GEN_ASSIST ransomware?
Hackers attack users yet with another crypto-ransomware called AES_KEY_GEN_ASSIST virus. Even now, when the most beautiful festivals of the year are approaching, crooks do not intend to give the virtual community a break from ransomware attacks. What is more, the malware seems to be one of the elaborate and complex ransomware. One of the distinctive features – .pre_alpha appended extension. Nevertheless, there is no need to give in to despair because of the encrypted files. Firstly, you need to remove AES_KEY_GEN_ASSIST completely from the device. Afterward, you may shift to data recovery procedure.
The emergence of well-known crypto ransomware, such as TeslaCrypt, CryptoLocker and Locky marked the beginning of a new era of ransomware viruses. After getting acquainted with AES and RSA encryption peculiarities, multiple hacker-wannabes joined the ransomware business. One of the possible reasons for such surge is ransomware-as-a-service . Cyber criminals publish ransomware samples for educating or sale purposes. Likewise, anyone willing to make a profit from such illegal activity can only purchase the necessary details and start distributing the malware. The main cause of such boom of file-encrypting malware is the method of AES and RSA algorithms. Aes_key_gen_assist malware exploits the compilation of AES-256 and RSA-2048 encryption method. The former key encodes the data while the latter, RSA, encrypts the very AES key . Therefore, the very process of decrypting victims‘ keys is surely not an easy task.
Guessing a matching key for Aes_key_gen_assist ransomware is nearly impossible. Likewise, hackers are confident that netizens will fail to decrypt the data without remitting the ransom. In comparison with other threats, the virus presents a few interesting peculiarities. Unlike the majority of crypto-ransomware viruses, it does not employ anonymity ensuring Tor network . Instead, in the !Read__Me.tXt file, the crooks present two email addresses for public communication: AES_KEY_GEN_ASSIST@protonmail.com and email@example.com. As common for hackers, they warn victims not to attempt decrypting the files on their own. Certainly, if your files happen to be of great importance, you might comply with the demands just to retrieve the files. However, few crooks are known for retrieving the files . Thus, paying the money might be just a waste of energy. What you should do is concentrate on AES_KEY_GEN_ASSIST removal. RestoroIntego helps you do that effectively.
The distribution tendencies of the malware
If you are wondering how this cyber threat has managed to infect your system, you should try recalling whether you received any suspicious spam email . In general, such emails remain the main distribution channel for racketeers to distribute the malware. Unfortunately, users still fall for old tricks when they receive fake police emails or delivery package messages. The crooks significantly improved in counterfeiting the emails of well-known companies. Nonetheless, there are still ways how you can suspect the reliability of such email. Look for grammar mistakes and typos. If the email pretends to be the message sent from an official institution, take a close look at the logo. Frequently, an altered icon might suggest that a cyber menace lies in the attached file. Alternatively, keep in mind that AES_KEY_GEN_ASSIST hijack might occur if you surf in a questionable website as well.

How to prevent from getting ransomware
Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
