The DEHD virus attacks the victim’s computer data by encrypting it with the military-grade algorithm. Files are not damaged by ransomware but are not usable with any software until decryption is applied. Hackers are hoping that computer users do not have a backup for recovery. The purpose is that scared person has lost important information (documents, pictures, video and, etc.); in this desperate situation, the decision would be made to contact them via provided emails: manager@mailtemp.ch and helpsupportmanager@airmail.cc Provided information in generated note pushes the victim to make a reckless decision urgently paying money for a personal ID key to decrypt all data. Motivating to transfer money instantly (max within 72 hours), criminals offer even a discount of 50%. If not enough time to correctly evaluate the stressed situation ransom amount will be doubled from $490 to $980. All conditions and prices are given to seducing money. If they succeed in enticing you to write an email about the lost data and the redemption amount, you will get strict guidelines for further process. First of all, they hide identity very well, and money will be accepted just in specified cryptocurrency. This communication way is completely untraceable because the crypto should be transferred to a virtual wallet generated from them. This move makes them unreachable by any government agency to make justice by federal law. This allows them to use the crime freely to find more and more victims who pay money. All worldwide experts, professionals, government institutions, the FBI pressingly advise not even think about contacting hackers. First, of all, it is illegal and forbidden by authorities in any country. Paying money will not guarantee that data will be recovered. By doing this, you will support cyber criminals and be involved in crime, possibly making even bigger harm for yourself and others. However, sometimes you can get one recovered file as proof that the rest data will be restored just after the payment is received, but it is zero guarantee that it will be done. Receiving any files or emails directly from criminals is extremely risky. Even with one click, you can install data-stealing software. It is very popular to install Trojans like AZORULT and VIDAR, and these apps will work secretly on the operating system without any visible harm like data locking or etc. The worm will collect all your sensitive data: user names and passwords, addresses, bank card details, virtual wallets. Then all information will be collected, and trojan transfers it to developers. They can sell your data on the dark web, they can steal from you directly; also, they can compel you to pay big money for it. Computer owners who have suffered harm from the STOP/DJVU ransomware family straightway need to isolate the PC from the local network. This will secure other working devices. It is very important to remove DEHD virus completely. This will make safe your not encrypted data. The most trusted and easy way to get rid of this unpleasant situation is trustable antivirus software the newest version will detect it and remove it automatically, just in a couple of clicks. Based on our experience, the INTEGO Antivirus will do the job perfectly. Another step is also very important. It is recommended to scan and check damaged Windows OS files. For this difficult task, you should use RESTORO this software which will do its job automatically.

Ransomware Summary

REPAIR VIRUS DAMAGE

Ransomware Distribution Ways

The most popular ways to distribute STOP/DJVU ransomware, same as the newest variant DEHD virus, are via P2P networks, fake updaters, third-party downloaders, pirate software, illegal software “key generators” same as “crack” application infiltrates into computer operation system malicious files. Cybercriminals tags the most popular and searchable applications with the newest virus editions. We provided a list of popular software downloaded or activated, not in a legal way.

Cubase;Adobe Photoshop;2K22;Tenorshare 4ukey;Internet Download Manager;AutoCAD;Opera browser;Adobe Photoshop;VMware Workstation;Adobe Illustrator;Minecraft;KMSPico (illegal Windows activation tool).

The only safe and legal way to obtain a wanted product or application is official websites with offers listed for each item. Also, you can get desired app or game from official partners, and it is completely safe. Victims usually search for an illegal way of software download or activation. For this decision, they are not saving but losing much more. This way, official developers lose money and are being robed. For this activity, breaking copyright rules are infringed, which can cause financial fines by local government law to compensate the developer losses. Another “reward” is infected computers, lost files, and sensitive data. Also, this way, you support cybercriminals. Note that malicious files are not spreading in legal ways. Ninety-nine percent of them come from torrents and other illegal ways. We need to mention that criminals use another channel to spread malicious files via email. They simply attach Microsoft Office files like (PDF, DOCX, XLS) and just only one sloppy download will infect a computer. All these files have macro functions or enabled JavaScript. Usually, ordinary users do not use them, but not hackers. Due to these advanced options virus locks the rest files on the hard drive. For infected STOP/DJVU ransomware users, we strongly advise not to rush finding decryptors on the internet. It is 100% that decryption code for the newest extensions is not developed yet. It takes time for programmers to find a way to unlock each new version, even not always able to do it. After infection, if you find offers for decryptors, it is probably a fake ZORAB STOP/DJVU decryptor. This action can damage your files completely, and later the original decryptor won’t help.

Comprehensive Technical Information About the Virus

This paragraph detailed explains the activity of DEHD virus contagion of the Operating System. This is useful for the experienced user who has IT skills removing ransomware manually. The very first action after the malicious file is opened in the computer regenerates build.exe or build2.exe and winupdate.exe. Then it generates duplicated windows screen letting it hide illegal actions. The worm collects information about your workstation: Region, Country, City, Location (latitude and longitude), Zipcode Time zone, and etc. Now it’s time to go online using your network to make the connection to https[:]//api.2ip.ua/geo.json All stolen information is saved on the geo.json file on the hacker’s server online mentioned before. Same time another document is generated and delivered to them – the information.txt file. All confidential details like IP addresses, Mac addresses, Hardware, Software are saved on it. STOP/DJVU ransomware family developers for all created extensions made a rule exception. Their system scans countries of infected users and if it detects: Russian Federation, Belarus, Ukraine, Syria, Crimea, Uzbekistan, Armenia, Tajikistan, Kazachstan, and Kyrgyzstan. If it detects that you are on it, it will stop doing any further actions, you won’t get any harm, and your files won’t be locked, the worm will pass away from the system. Differently, if you are not on the list and belong to the rest of the world, infiltrating steps will go further. Command&Control server generates a unique encryption key directly linked to personal ID. All these important details will be saved to bowsakkdestx.txt and PersonalID.txt files. Now is the most important part of it. If encryption goes smoothly and successfully will be created online key. This variant is bad news to the victim because it is zero chance to recover files without the original key. Any decryptor or programmer can help with this. If encryption doesn’t go smoothly and has some difficulties, an offline key will be generated. It is really good news because it has great chances to get lost data back. Both variants lock files by the military-grade algorithm ( Salsa20 & RSA-2048). The question is hot to recognize which type of encryption is applied? It is very easy to recognize even for a beginner in hackers demand you will get unique personal ID if the last two letters are t1 it is offline decryption, any another variant is online. The final stage – computer users cannot open files with any application, for example, picture affected by ransomware changes extension, in this case by DEHD virus, Holidays.jpg has changed to Holidays.dehd also nearby in the same directory _readme.txt note will be left. Some STOP/DJVU ransomware edition has extra functions, and it will delete. Then, the malware will delete Volume Shadow preventing computer users from the ability to use Windows OS function recover to existing System Restore Point. It helps to recover computer data and files to date it was created restore point. Hackers also created their own blacklist of websites with free recovery instructions like ours to the Windows HOSTS file. Browsers won’t load the blocked websites, showing DNS_PROBE_FINISHED_NXDOMAIN error; you can fix it by reading provided guide.

Decrypt DEHD files

Fix and open large DEHD files easily:

It is reported that STOP/DJVU ransomware versions encrypt only the beginning 150 KB of each file to ensure that the virus manages to affect all files on the system. In some cases, the malicious program might skip some files at all. That said, we recommend testing this method on several big (>1GB) files first.

STOP/DJVU decryption tool usage guide

STOP/DJVU ransomware versions are grouped into old and new variants. DEHD Ransomware Virus is considered the new STOP/DJVU variant, just like BPTO, ISWR, ISZA, BPSM, ZOUU, MBTF, ZNSM (find full list here). This means full data decryption is now possible only if you have been affected by offline encryption key. To decrypt your files, you will have to download Emsisoft Decryptor for STOP DJVU, a tool created and maintained by a genius security researcher Michael Gillespie. Note! Please do not spam the security researcher with questions whether he can recover your files encrypted with online key - it is not possible. In order to test the tool and see if it can decrypt DEHD files, follow the given tutorial.

Meanings of decryptor’s messages

The DEHD decryption tool might display several different messages after failed attempt to restore your files. You might receive one of the following messages: Error: Unable to decrypt file with ID: [example ID] This message typically means that there is no corresponding decryption key in the decryptor’s database. No key for New Variant online ID: [example ID]Notice: this ID appears to be an online ID, decryption is impossible This message informs that your files were encrypted with online key, meaning no one else has the same encryption/decryption key pair, therefore data recovery without paying the criminals is impossible. Result: No key for new variant offline ID: [example ID]This ID appears to be an offline ID. Decryption may be possible in the future. If you were informed that an offline key was used, but files could not be restored, it means that the offline decryption key isn’t available yet. However, receiving this message is extremely good news, meaning that it might be possible to restore your DEHD extension files in the future. It can take a few months until the decryption key gets found and uploaded to the decryptor. We recommend you to follow updates regarding the decryptable DJVU versions here. We strongly recommend backing up your encrypted data and waiting.

Victims of DEHD Ransomware Virus should report the Internet crime incident to the official government fraud and scam website according to their country:

In the United States, go to the On Guard Online website.In Australia, go to the SCAMwatch website.In Germany, go to the Bundesamt für Sicherheit in der Informationstechnik website.In Ireland, go to the An Garda Síochána website.In New Zealand, go to the Consumer Affairs Scams website.In the United Kingdom, go to the Action Fraud website.In Canada, go to the Canadian Anti-Fraud Centre.In India, go to Indian National Cybercrime Reporting Portal.In France, go to the Agence nationale de la sécurité des systèmes d’information.

If you can’t find an authority corresponding to your location on this list, we recommend using any search engine to look up “[your country name] report cyber crime”. This should lead you to the right authority website. We also recommend staying away from third-party crime report services that are often paid. It costs nothing to report Internet crime to official authorities. Another recommendation is to contact your country’s or region’s federal police or communications authority.
