PIIQ ransomware can be defined as a virtual extortion tool developed by malevolent programmers. It is part of one of the largest encryption-based computer virus families today, known as STOP/DJVU. The primary aim of this ransomware is to use military-grade encryption algorithms to temporarily lock files on victim’s computer until a ransom is paid. It is obvious that people keep their important files on either personal or work computers, and the idea of losing all of them in a few minutes is scary. Cybercriminals expect that victims will be willing to do anything it takes to recover these files. Therefore, they demand purchasing cryptocurrency worth $490 or $980 and transfer the said sum to criminals’ virtual wallet. As stated before, the criminals demand lower ransom if the victim manages to sort out the payment problem within 3 days. Otherwise, the price increases to $980. To encourage the victim to not hesitate and pay the ransom sooner, the criminals suggest testing the decryption first. They ask to send one small encrypted file to them and promise to reply with a decrypted version of it. However, they warn that the test file should be small in size. In addition, they might refuse to decrypt this file in case it contains valuable information, as this could refrain the victim from paying the ransom at all. Geek’s Advice team members do not recommend paying the ransom. In addition, FBI won’t advise doing so as well. Some of the reasons why you should pay up are:

Promises of Internet criminals do not mean a thing. They cannot be traced down, therefore they are not obliged to keep their promises. You might end up losing your files and your money because paying the ransom doesn’t automatically guarantee file recovery. In some countries and states, paying the ransom might be illegal.Ransomware-type threats rake up hefty amounts of money each year. The large sums of money that criminals collect attract other people to join the illegal business model as distributors or malware developers. For this reason, we suggest you refrain from listening to virtual extortionists’ demands!Viruses from STOP/DJVU ransomware family such as PIIQ virus drop AZORULT Trojan on compromised computers or networks. This Trojan can be used to steal sensitive information from victim’s computer, such as browser-saved passwords, login credentials of Skype, Steam or Telegram and even more. Such information easily allows criminals to blackmail you later via phishing emails or other contact forms.

Ransomware attack in detail: damage explained

PIIQ ransomware begins the computer infection by launching a fake Windows update prompt (winupdate.exe process). The meaning behind this masquerade is that virus’ developers want to make the computer user believe that a sudden PC slowdown is caused by a Windows operating system update. However, the computer slows down because the ransomware is in action as it scans the whole computer system, looking for target files to encrypt. To complete the data encryption faster before the victim notices anything, the ransomware encrypts only the first 150KB of each file, which is enough to guarantee file corruption. However, we must mention that such type of encryption also allows the victim to easily restore or repair certain file types with minimal data loss, for example, you can learn how to restore audio or video files with some seconds of content missing at the beginning of the file. Speaking of other ransomware activities, it also creates and drops _readme.txt ransom notes in every affected data folder. The ransomware operators clearly want the victim to notice this file and open it. The malware doesn’t stop there and also delete Volume Shadow Copies from computer. These are essential when trying to use System Restore Points. In other words, the malware makes any free file recovery means as complicated as possible. Next, this virtual menace adds a list of computer-related websites to Windows HOSTS file, hoping to prevent the victim from visiting them. In fact, if the victim attempts to access one of these domains directly or, say, via online search engine, DNS_PROBE_FINISHED_NXDOMAIN will come up. It is believed that ransomware operators try to prevent the victim from visiting certain domains to keep relevant cyber attack-related information inaccessible. The said ransomware is also known to distribute AZORULT malware to compromised systems. To put it simply, it is a information-stealing Trojan that can be controlled remotely by an attacker. Some of its functionalities include:

Download malware to victim’s computer and run it;Steal Steam, Telegram login credentials;View or delete files on victim’s computer;Steal cryptocurrency wallets;Steal browser cookies, saved passwords, browsing history and more.

That said, we strongly recommend you to remove PIIQ ransomware virus along with AZORULT and other possibly installed malware using professional antivirus tools. The one that we recommend excellent malware detection rate, real-time protection and fair price – it is INTEGO Antivirus. Use it to remove malware on your computer, but make sure you boot your PC in Safe Mode with Networking first as explained in the guide below. Finally, we strongly recommend using RESTORO to repair ransomware damage on Windows OS files.

Ransomware Summary

Ransomware distribution tricks you should beware of

Computer viruses that fall in ransomware category are typically distributed using the following strategies:

Malicious torrent downloads

Malicious torrent downloads is a popular ransomware distribution technique and it is the primary method used to spread STOP/DJVU ransomware variants such as PIIQ virus. The criminals target computer users who are looking to get paid software or game versions for free and are willing to use so-called cracks or key generator tools to activate licenses without paying anything. Unfortunately, such tools are often complimented with malicious payloads. Even if the victim doesn’t notice anything after installing the desired software or game, the damage can be done already. For example, computer users can get infected with malware that has a timer to execute at a specific time or act silently (for instance, cryptocurrency miners, Remote Access Trojans and similar). What makes this ransomware (and malware in general) distribution technique so successful is that computer users even tend to ignore their antivirus’ warnings about a potentially malicious file because some tend to believe that these are false alarms related to the name “crack.” However, that is untrue in the majority of cases. If you wish to download safe software or game versions, make sure you visit the official developer’s or distributor’s website. It is the easiest way to avoid unwanted computer infections, besides, legitimate software licenses cost way less than hefty ransoms that cybercriminals demand.

Email spam campaigns

Please remember that cybercriminals are extremely skillful nowadays and so are the attack techniques they use. While EXE used to be the primary file format used to deliver malware to potential targets, now times have changed. Criminals can attach malicious malware-downloading script into any file format that supports JavaScript or macro functions. For example, nowadays some of the most popular file formats used to transmit malware are PDF, XLS, DOCX. Additionally, criminals actively use email spoofing technique to make the email sender’s address appear legitimate. We strongly recommend you to learn more about email spoofing and ways to identify such emails here.

Fake ransomware decryption tools

Ransomware victims should beware of another sneaky malware distribution technique based on fake decryption tools. Criminals that come from other ransomware gangs tend to inject their creations in fake decryption tools that victims of STOP/DJVU malware tend to download carelessly. One of such ransomware families known for usage of such deceptive distribution tactics is Zorab. Therefore, keep in mind that attempts to download suspicious “decryption” software might result in double file encryption.

Decrypt PIIQ files

Fix and open large PIIQ 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. PIIQ 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 PIIQ files, follow the given tutorial.

Meanings of decryptor’s messages

The PIIQ 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 PIIQ 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 PIIQ 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.
