How dangerous can DynA-Crypt attacks possibly get?

DynA-Crypt virus is a malicious crypto-ransomware [1] and an information-stealing malware which does not only leave little hope for the victims to retrieve the encrypted files, but also puts them at high risk of potential data leak. According to the attackers, the only way to roll back the corrupted system back to its original state is by sending a set amount of money to an indicated Bitcoin wallet account [2] and receiving a personalized decryption key. To put it simply, hackers hold victim’s files hostage and demand money in exchange. The amount of ransom may vary depending on multiple factors, including the volume of the encrypted files and their importance. Typically, though, the sums fluctuate somewhere between 500 to 1500 USD. It does not matter whether the ransom is small or extensive, transferring money to the criminals can be dangerous. There are numerous examples of cases when the hackers fail to deliver the promised decryption software, or the utilities turn out to be useless. Thus, the files remain encrypted. Besides, regardless of whether you decrypt your files or not, your money will still be supporting the hackers and allowing them to extend their fraudulent business even further. Thus, we strongly advise you not to trust the criminals and remove DynA-Crypt from your computer instead. Please note that the virus should not be approached manually. Do not go deleting random files in hopes of decontaminating the virus but use specialized software, such as FortectIntego instead.

DynA-Crypt malware is a DynAmite Malware Creation Kit [3] build which means it was created using an already existing template. This particular kit is distributed on the darknet [4] with detailed instructions how to use it, so any evil-minded individuals can easily put their hands on it and create their own ransomware variant. The DynA-Crypt developers, in particular, have customized this virus to look for certain types of files on the infected devices and once they are encrypted, append them with “.crypt” extensions. Luckily, the virus leaves the original extension and the filename intact, which can save you trouble and confusion when it comes to data recovery. Unfortunately, DynA-Crypt is capable of much more than regular data encryption. It also works against your computer system, messing up with its settings, disabling essential functions, even deleting applications and stealing login information saved on your Firefox or Chrome browsers. In fact, according to the latest findings, the virus may also take live screenshots of your desktop, log your keyboard activity, record internal sounds and extract information stored on the installed applications, including Skype, Steam, Minecraft, Chrome, TeamSpeak. The collected data is copied to the infected computer’s %LocalAppData%\dyna\loot\ directory, on which it later can be archived and sent to the malware developers upon C&C request. And that’s not even the worst part. Most of the collected data will be deleted from the original folders along with all the desktop information. It is absolutely crucial to address DynA-Crypt removal as soon as possible to prevent the potential data loss, data breach, identity theft [5] or even financial loss.

Don’t blame your antivirus — ransomware infects careless web surfers:

DynA-Crypt is a ransomware that will use all the ways possible to infect computers. It might spread with the help of Trojans, bogus software updates or peer-to-peer networks, but most likely, it will infiltrate the system through a malicious email attachment. This is a classical technique that ransomware developers use to deploy these viruses on the unsuspecting victim’s computers. To be precise, hackers fool the users into downloading the malicious attachments themselves, by disguising them as a document carrying information which might be essential to the user. Such malicious emails often end up in the spam folder. Thus we recommend staying away from it, unless absolutely necessary. Do not let DynA-Crypt trick you! Think twice before downloading any attachments on your computer, especially if they have arrived along with emails received from some unfamiliar senders.

What are the core steps of the DynA-Crypt removal?

There aren’t a lot of options to choose from when it comes to DynA-Crypt removal. The virus is a dangerous cyber threat. Thus it should be treated accordingly. Generally speaking, the removal should be carried out using specialized antivirus or anti-malware software, but are some additional steps that could help you remove DynA-Crypt virus more smoothly and ensure that no malicious components are left on your computer. These handy techniques are described below where you will also find tips on how to recover your data after the DynA-Crypt attack.
