Decrypt files with .zepto extension and delete Zepto trojan

.Zepto obviously stems from the notorious Locky ransomware. On the other hand, it displays a number of distinctive features. The infection is a stand-alone piece of malware.

IT security actors report its ongoing outbreak. Powerful botnets contribute to its mass-propagation. The compromised accounts mass-mail a message that pretends to be a set of important business notifications. The documents arrive attached and archived. A victim triggers the ransomware installation by opening the attachment.

Once the installation has completed, the rogue proceeds with scanning the affected systems. The scam covers any locations the infection can reach. That is, data on removable media and networks shares also undergo encryption. The virus avoids some file formats to avoid a system crash. After all, the crooks need a compromised machine to run, for they need their victims to read the ransom note.

Zepto cycles the data a dozen times. The output is remote from the input by many generations of encryption . The algorithm applied is AES which features a 128-bit  encryption key. That is, it splits the data into units of 128 bits. Each unit is subject to the multiple cycles of a sophisticated modification. Further on, the trojan encodes the key with RSA scrambling standard. The latter is basically even stronger than the AES. Finally, it sends the keys to its remote server via protected channel.

The files encoded have their names badly tweaked. They acquire a gibberish set of digits instead of the original. A victim cannot tell which is which. Zepto extension appears at the end of the affected items.

The infection creates its ransom order at every folder. Besides, the notification replaces desktop wallpaper. The ransom reminder demands the fee of 0.5 bitcoins for the delivery of decryption tool. Some victims have no choice but to try rescuing their data at any price. Meanwhile, there are efficient data recovery methods to try. These cannot decrypt the affected items, but may recover the files to the extent that satisfies your needs. Besides, the follow-up parts of this article will show you how to get rid of Zepto ransomware. Please note the removal of Zepto trojan is essential. Abandoning the extermination may lead to the repeated encryption and further malware invasion.


All of your files are encrypted with RSA-2048 and AES-128 ciphers.

Automated cleanup to remove “!!! IMPORTANT INFORMATION !!!” decryptor:

Infection vector for ransomware typically features a trojan. The one in question definitely subscribes to that routine. The trojan drops its body into target computer and proceeds with disabling the detecting functionality of any security solution installed. The antivirus is thus unable to spot introduction of virus from the remote server.
The ransomware invasion is indicative of its dropper residing in the computer memory. It also hints at other invasions. The PC can hardly be considered properly protected due to the impacts of the above trojan.
Ultimate option implies a total formatting for any drives of your PC. That is not an option for many users, for it destroys all the data hosted by the machine. The best solution to pick would be in-depth system examination with a reliable security suite.
The trojan that has installed Zepto ransomware (!!! IMPORTANT INFORMATION !!!), unless removed, is to trigger its installation campaign as soon as a new strain of ransomware is available. Thereby, it is critical to kill it as soon as possible.

The technique successfully overcomes malicious software, including any ransoming threats. It deploys a reputable security suite that offers not a single chance for malicious components to avoid detection and extermination. The software is incredibly user-friendly and operates on a single-click basic.

It is good to note the removal of Zepto virus does not recover the data affected. However, the virus is subject to compulsory extermination or else is going to introduce related infections into the machine.

1. Click the button to download the stub installer and go through several setup dialogs. Once the tool is up and running, click Start Computer Scan

2. Wait until the cleaner checks the PC for Zepto ransomware files malicious code. As soon as the scan is completed, the report will list all malware objects spotted in the system. Make sure the entries for detected infections are checked, and select the Fix Threats feature. This will result in malware removal and system remediation, so you should now be good to go.

Restore the encrypted files

.zepto ransomware encryption is a sophisticated data modification. There is no simple and single solution to cover all the cases. Transferring the ransom as demanded by the crooks is not the way either.Kindly apply the methods outlined below as they have been carefully developed to provide a recovery help for the most severe cases of encrypting assaults.

Data recovery with automatic software

Good news is that the virus actually deals with copies of the files. The originals have been deleted. The removed data still can be restored by virtue of such tools as Data Recovery Pro.

Shadow Volume Copies

As Windows creates backups at given periods of time, a victim is advised to address relevant restore points. Unfortunately, the method cannot apply unless the System Restore had been enabled prior to the invasion. Please also note the recovery returns files as saved before the time associated with the restore point addressed.

  • Previous Versions dialog to target individual files
    One can open Properties for any file. The menu has a tab called Previous Versions. It indicates versions of a file that have been backed up.
    To make use of the feature, right-click an affected file and choose Properties in the drop-down list. Proceed with clicking the above-mentioned tab. You can opt between the Copy or Restore procedures, the former enabling to copy the item into the location specified by the user.

Backups and removing remaining traces of the Zepto virus

Prevention is the best cure. If you stick to making regular reserve copies of your data and store those outside your operating system, the impacts by the ransomware are very limited. However, prior to copying the data from backups into the system hit by “!!! IMPORTANT INFORMATION !!!” ransomware, make sure the removal of Zepto virus has completed.

Your manual removal attempts may kill the ransomware in general. In most of the cases, some remnants manage to survive and are still capable of causing a significant damage. Please apply a reliable anti-malware scanner to detect and remove, if applicable, any remaining infections.
