What is Jager ransomware virus?

Analysis of Jager virus

Hackers surely do not rest as they come up with a new file-encrypting malware – Jager virus, alternatively known as JagerDecryptor. This ransomware seems to be a complex and well-programmed malware. It employs AES encryption algorithm to encode personal information. It has not spread widely yet, but it is expected to do so in the following weeks. Therefore, it is of crucial importance to cease it before it goes viral. If this malware has already occupied your device and you are about to panic, collect yourself. In this article, we will tell you how to remove Jager ransomware effectively. You can start installing FortectIntego as it will help you perform the elimination properly.

Specifically, with the help of AES-256 ciphering, this ransomware locks out your files. What is more, in order to encode the files completely so that users would not be able to decrypt them easily, the ransomware also employs RSA key. As a result, the only solution to retrieve the files is to obtain the private key which is mathematically related to the public key. What is more, unlike other ransomware threats, this variant does not add any particular file extensions to encrypted data.

All in all, if the files are of high importance, you should not consider paying the money as a possible option. Cyber criminals are not obliged to return your data to you even after receiving the ransom. Speaking of which, hackers enjoy terrorizing victims by setting a time limit for the receipt of ransom. They urge users to purchase JagerDecryptor in order to retrieve the blocked data. In addition, they state that they will allow you to decode one file up to 200 KB to convince you that the decrypting software works properly. Furthermore, if a victim does not remit the payment within 72 hours, the data is said to be lost. Moreover, after each day, the sum of required money increases by ¼. Unfortunately, IT specialists have not still developed a proper decryption tool, because hackers seem to cancel one of their servers where the sample of this virus was obtained. Therefore, you should solely concentrate on Jager removal instead.

Files and programs related to this ransomware

JagerDecryptor virus. This piece of malware is on the market as the “official” Jager decryption tool, offered by authors of this ransomware. To receive and use it, victims are obliged to pay a ransom via Bitcoin payments system. The payment can be made via JagerDecryptor payment site. We highly recommend not to buy this tool as it can pose a threat to your computer and possibly plant more harmful programs, such as Trojans on it. Even if this software decrypts your files, make sure you scan your computer with a trustworthy anti-malware tool and remove all remains of these noxious pieces of software. For those who did not pay the ransom, we suggest waiting; do not delete encrypted data from your PC, because malware researchers work every day and do their best trying to crack ransomware viruses and build free decryption tools. Therefore, we assume that one day a free decryption tool for this virus might be created as well.

When did the ransomware infect my computer?

It is likely that this virus spreads via insecure domains and P2P file sharing domains. Spam emails, which are the preferred distribution channels by the majority of hackers, should not be excluded as an option as well. Cyber criminals have mastered this particular strategy quite well. Users, opening fake emails from transportation agencies or tax institutions, often fall for the deception. Do not rush opening any emails with the attachments which are said to be invoice or package delivery documents. In case, you are waiting for a parcel, contact the institution directly. Cautiousness will save you not only from Jager malware but from other file-encrypting viruses.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
