Verasto ransomware removal instructions
What is Verasto?
Verasto is high-risk ransomware discovered by Michael Gillespie. This malware belongs to yet another variant of a ransomware virus called Djvu. As with its predecessor, Verasto encrypts stored data and renames each compromised file by adding the ".verasto" extension (e.g., "sample.jpg" is renamed to "sample.jpg.verasto"). Encrypted data instantly becomes unusable. Additionally, Verasto stores a text file called "READ_ME.txt" in every existing folder.
The new text file contains a message identical to those provided by other ransomware from the Djvu family. It essentially states that data is encrypted and can only be restored using a unique decryption tool/key. Unfortunately, this information is accurate. It is currently unconfirmed whether Verasto uses symmetric or asymmetric cryptography, however, each victim receives a unique decryption key, which is necessary to restore data. All keys are stored on a remote server controlled cyber criminals. Therefore, to receive a key (together with a decryption tool) and recover data, each victim must pay a ransom of $980. To receive all payment details and decryption instructions, victims must contact cyber criminals via an email address provided or telegram. It is also stated that victims who contact these people within 72 hours after encryption will receive a 50% discount (the cost will drop to $490). In any case, you should never agree to pay. Cyber criminals usually ignore victims, once payments are submitted. Therefore, ignore all requests to submit payments or even contact these people. Unfortunately, Verasto is undecryptable ransomware - there are no tools capable of cracking its decryption and restoring data free of charge. The only solution is to restore everything from a backup, if one has been created.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
The internet is full of ransomware-type infections, all of which are very similar. For example, Phoenix-Phobos, Exploit, and Cube. Most ransomware infections compromise data (typically, by encryption) and make ransom demands. Unfortunately, ransomware infections typically employ cryptographies such as RSA, AES, and similar that generate unique decryption keys. Therefore, unless the virus is still in development or has certain bugs/flaws (e.g., the key is hard-coded, it is stored locally or similar), manual recovery without the help of developers is impossible. Ransomware is one of the main reasons why you should maintain regular backups, however, store them on a remote server/unplugged storage device (e.g., Cloud, Flash drive, external hard drive, etc.), since locally stored backups are encrypted with regular data.
How did ransomware infect my computer?
The way in which cyber criminals proliferate Verasto is currently unknown, however, ransomware is usually spread using trojans, fake software updaters/cracks, third party software download sources, and spam email campaigns. Trojans are simple - they are malicious applications that stealthily infiltrate computers and inject them with additional malware. Fake software updaters infect computers by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than the promised updates. Cracks bypass paid software activation, however, since criminals often use them to proliferate malware, users are much more likely to infect their computers than gain access to paid features. Unofficial software download sources are used to proliferate malware by presenting it as legitimate software. In doing so, cyber criminals trick users into downloading and installing malware manually. Cyber criminals use spam email campaigns to send hundreds of thousands of emails consisting of malicious attachments and deceptive messages encouraging users to open them. The attachments are typically presented as receipts, invoices, bills, or other important documents - this to give the impression of legitimacy. In fact, the result is identical: infiltration of malware. In summary, the main reasons for computer infections are poor knowledge of these threats and careless behavior.

How to protect yourself from ransomware infections?
To prevent computer infections, be very cautious when browsing the internet and downloading, installing, and updating software. Never use third party downloaders/installers, since these tools often include rogue apps. Software should be downloaded from official sources only, using direct download links. Similar rules apply to software updates. Keep installed applications and operating systems updated, however, this should be achieved only through implemented functions or tools provided by the official developer. Software piracy is a cyber crime. Furthermore, the risk of computer infections is extremely high. Therefore, you should never attempt to crack known installed applications. Finally, have a reputable anti-virus/anti-spyware suite installed and running, since these tools can detect and eliminate most computer infections before they do any harm. If your computer is already infected with Verasto, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Screenshot of files encrypted by Verasto (".verasto" extension):
Malware researcher Michael Gillespie has developed a decryption tool that might restore your data if it was encrypted using an "offline key". As we mentioned, each victim receives a unique decryption key, all of which are stored on remote servers controlled by cyber criminals. These are categorized as "online keys", however, there are cases when the infected machine has no internet connection or the server is timing out/not responding. If this is the case, Verasto will use an "offline encryption key", which is hard-coded. Note that cyber criminals change offline keys occasionally to prevent multiple encryptions with the same key. Michael Gillespie continually gathers offline keys and updates the decrypter. Nevertheless, the chances of successful decryption are still very low, since only a very small portion of "offline keys" have been gathered. You can download the decrypter by clicking this link (note that the download link remains identical, even though the decrypter is continually updated). Your files will be restored only if the list of gathered keys includes the one that was used to encrypt your data.

As with most of ransomware from the Djvu family, Verasto also displays a fake Windows update pop-up during the encryption:
IMPORTANT NOTE! - As well as encrypting data, ransomware-type infections from Djvu malware family also install a trojan-type virus called AZORult, which is designed to steal various account credentials. Moreover, this malware family is designed to add a number of entries to the Windows hosts file. The entries contain URLs of various websites, most of which are related to malware removal. This is done to prevent users from accessing malware security websites and seeking help. Our website (PCrisk.com) is also on the list. Removing these entries, however, is simple - you can find detailed instructions in this article (note that, although the steps are shown in the Windows 10 environment, the process is virtually identical on all versions of the Microsoft Windows operating system).
