Zepto virus keeps taking personal files to hostage

Zepto virus works as a greatly destructive file-encrypting virus. It resembles Locky virus which has been labeled the most aggressive ransomware of 2016 [1]. The malware disperses with the help of spam - more than 150,000 infected spam messages have been released [2]. Typically, people are tricked into downloading an infected .zip or .docm attachment by tempting subject lines, such as "Please, see the attachment, "To the head of sales", "Scanned image", etc. Similarly to Bart ransomware, this cyber threat needs to convince its victims to launch a JavaScript file or enable macros. Once it's done, it encodes files with RSA-2048 and AES-128 ciphers. As a result, they get blocked bearing .zepto extension. At the end of the encryption process [3], Zepto ransomware changes the desktop picture with an image that presents information about the virus and a request to pay a ransom. If this menace has befallen you, you might think that there is no way to remove Zepto. Take into the consideration that hackers apply emotional pressure to persuade users to hurry with the payment [4]. Likewise, they succeeded in collecting more than $100,000 with the help of this ransomware. Let us assure that there are ways to complete Zepto removal. The most effective of them is to use Reimage

Just as other ransom-demanding viruses, this virus leaves ransom notes called _[2 chars]_HELP_instructions.html and _[2 chars]_HELP_instructions.txt on several folders, which hold the information about the decryption process. It states that there is no other way to decrypt files but to pay a ransom and receive a private key and a decryption program. Instructions on how to access Zepto payment site are also provided by this virus. During the investigation process, we discovered that the payment site advertises Locky decrypter which was used by another ransomware called Locky. Now it can be purchased for 4 Bitcoins (approximately 2541 USD). Of course, you should never think of that because you can be left without both, your files and your money. To recover your data, you should remove Zepto first and then restore your files from back up. Take a look at the ransom note: 

!!! IMPORTANT INFORMATION !!!!

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

4. Follow the instructions on the site.

After Locky rampaged on the virtual world for a couple of months, soon afterward, the cyber campaign of Zepto malware was launched. It reached its peak in July. Ordinary and corporate users all around the world were assaulted by this cyber menace. As previously mentioned, the threat employs swift [XXX|XXXX].js file for a disguise. By pretending to be a financial report or invoice, it captures victims' attention. Opening the attachment enables Zepto to start its mischief in thousands of computers. After sending HTTP GET requests, the threat is able to get important information about victims computers. This also enables it to infect the bigger amount of computers. By planting its wscript.exe executable [5] among the registry files, the ransomware keeps the device in its claws even if you reboot it. Moreover, the virus has been updated to such extent that even Windows Defender fails to block it. Therefore, it is of crucial importance that your security applications are updated daily. Moreover, not only Zepto but recently emerged ODIN ransomware appeared as a backup to the original version of the threat. It seems that the cyber criminals do not intend stepping aside.

What’s new about Zepto ransomware?

Even though many new variants of the Locky have recently appeared, Zepto virus stays active and still uses various infiltration techniques to infect computers all over the world. According to latest malware analysis, its activity increased up to 150% during the last month. Malware actively targets European countries, the United States, South America and East Asian regions. Lately, virus researchers spotted that Locky ransomware, as well as its newest version - .aesir file extension virus, stepped in Facebook. Malware started spreading via Facebook’s messages by sending malicious SVG image file. Victims, who clicked on it, were redirected to a suspicious domain that looked like YouTube. However, they were asked to install the plugin to play the video. This bogus plugin is Nemucod Trojan which is responsible for activating malware on the affected computer. Malware analysts expect Zepto ransomware to spread on Facebook or others social networks as well. Therefore, chances to catch this computer infection stay high. Unfortunately, ransomware attack may end up with a huge loss because file decryption tool has not been created yet. The only free and safe data recovery solution are backups.

The short reminder of the Locky virus

Locky virus was first detected in the beginning of February. Since then, it has been updated for several times. It is believed that the most of its updates were introduced for making the decryption tools, that are typically presented by security firms, useless. However, hackers have also improved the protection of their identity, increased the amount of its ransom and improved virus ability to block anti-spyware software.

Zepto ransomware virus is not as advanced as its previous version. However, security experts have already started making Zepto virus decryption tool which should be quite similar to Locky decrypter and should show up anytime soon. This virus was, and still is, one of the most powerful ransomware variants and none of the malware researchers attempts’ to create a decryption tool for it were successful. Unfortunately, it seems that these cybercriminals know what they are doing, and they do take advantage of their programming skills because their malicious programs appear to be uncrackable. If you are reading this article and your computer is not infected yet, please follow these rules to protect your computer from this ransomware and avoid a need to deal with Zepto removal:

  • Install an anti-malware software on your computer to keep it protected from malicious viruses;
  • Keep all your software up-to-date. Our tip is to enable automatic updates;
  • BACK UP your files. In fact, this is the only way to secure your data from encryption. You have to create file copies and save them on a removable storage drive, and then unplug it from your computer. You can use backups in case your computer gets hit by a ransomware;
  • Never open suspicious emails or files attached to them! Cyber criminals distribute this virus by sending deceptive letters to thousands of email accounts, claiming that they are delivering invoice, phone bill, speeding ticket, CV, or a similar document.

Ransomware distribution techniques and methods

As we have already mentioned, authors of this virus create fake email accounts and send officially-looking files, usually Word documents. Typically, these crooks insert malicious codes into a .zip and .docm files which are named using tricky titles. Such malicious code can be activated via Word Macros function or by launching JavaScript file, so make sure you don’t do that in case you see a scrambled text after opening Word document that you have received via email. Criminals also send JS files, which can be activated just by opening them. In addition, though such method is not widely practiced, but beware of exploit kits. They might be trojans, rogue  malware or any malignant files. By passing themselves off as legitimate files they might slip into the system and then when the time comes launch Zepto malware. In order to decrease the possibility of such malware attack, do not forget to update your security applications daily.

In general, we recommend you to avoid clicking or opening any kind of content online if you are not sure if it is secure. Cyber criminals use numerous techniques to deceive computer users, and it can be hard to keep up with the news and know all sources of infection. We advise you to protect your computer with anti-malware software, back up your data, and stay away from suspicious emails and websites.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Zepto from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Zepto, you can use several methods to restore them:

Use Data Recovery Pro to recover your files encrypted by Zepto

Originally, Data Recovery Pro was created to retrieve the files after an unexpected system crash or simply after the careless elimination of the files. However, you can also try using it to recover your important files.

Rely on Windows Previous Versions functionality to recover files affected by Zepto ransomware

You should be able to recover the data using Windows Previous Versions feature if the System Restore was enabled on your computer. For that, use the following guide: 

  • Find an encrypted file you need to restore and right-click on it;
  • Select "Properties" and go to "Previous versions" tab;
  • Here, check each of available copies of the file in "Folder versions". You should select the version you want to recover and click "Restore".

Use Shadow Explorer to decrypt encrypted files

One of the main features of Locky and its "cousin" Zepto, which helped it to retain the title among ransomware threats, is its ability to locate and delete the volume shadow copies. They are automatically created by the operating system in case a system is crashed unexpectedly. However, you should still try to recover your files encrypted by Zepto ransomware with the help of these steps:

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select "Export". You can also select where you want it to be stored.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Zepto and other ransomwares, use a reputable anti-spyware, such as Reimage, PlumbytesWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware

Yes, I was hit with the same virus, Zepto I was lucky though because I had a backup program called Carbonite which backed up my files dally. I called them after I discovered the attacked and was told these steps all if which were guided for me by the people at Carbonite at no charge. First, they uninstalled their program. And they told me to use an anti-virus for removal. I actually used a few just to be sure. When I was confident that all the encrypted files were removed, I called them back and they went through the process of installing the backup again. In fact, they were so helpful that they did a remote login and did everything for me. After completion everything should be back to normal as they reset the date before the problem. Folders will be added first and the the files back into the folders.

I use a cloud backup, but I am still screwed as it will take me weeks to get my machine to a productive state again after restoring. Government is useless. I get robocalls all day even though theres a who government agency centered on preventing them. Someone needs to hack the hackers. I will give a $100 reward to anyone who finds these people that made zepto. Im sure everyone in this thread will too.

people, backups are your life-savers, just create them, it is easier than to sorrow over encrypted files later on! Locky authors are unstoppable, Zepto is going to be as dangerous as Locky was. I cannot understand how these crooks manage to hide themselves from legal authorties! They should be put behind bars!
