What is Phorpiex?

Phorpiex (Trik) is the name of a malicious program that sends spam (mainly sextortion emails) from infected computers. Research shows that previously it was used to proliferate other malware (GandCrab, Pony, and so on). Phorpiex is not new malware and has been active for virtually ten years, infecting hundreds of thousands of computers. To avoid inadvertently receiving emails sextortion spam campaigns, we strongly recommend that you remove Phorpiex/Trik immediately.

Typically, sextortion scams comprise emails stating that the recipient's computer is infected and/or hacked and that people (cyber criminals) behind them have recorded a compromising video while the victim was visiting adult (or other similar) websites. The main goal of these emails is to blackmail recipients by stating that the recorded video/s will be sent to other people distributed over the Internet, and so on, unless a cryptocurrency sum is paid. Scammers behind these campaigns often use an email spoofing method: they change the sender's email address to recipient's address to make it seem as if the recipient's email account was hacked. Phorpiex is malware that is used to proliferate many emails of this type from computers of its victims without their knowledge. The more computers are infected with Phorpiex, the greater the chance that someone will fall for a sextortion scam that is distributed through this malware. We strongly recommend that you remove Phorpiex from the system immediately.

"Your device was infected with my private malware" is an example of a sextortion scam distributed by Phorpiex, however, this malware is also used to proliferate many different emails of this type. All are used to extort money from unsuspecting people. Never trust the emails - the best option is to simply ignore the message and delete them.

How did Phorpiex infiltrate my computer?

Typically, malicious programs are proliferated through spam campaigns, untrustworthy download sources, fake software updaters, software 'cracking' tools and Trojans. To proliferate malware via spam campaigns, cyber criminals send emails that contain malicious attachments (or web links that download malicious files). They usually include Microsoft Office documents, archive files (ZIP, RAR), PDF documents, executable files such as .exe, etc., and hope that recipients open them. Once opened, these attachments install malicious programs. Untrustworthy software download sources such as Peer-to-Peer networks (torrent clients, eMule, etc.), free file hosting, freeware download websites, unofficial pages, third party downloaders, and other similar channels/tools are also used to proliferate malware. Computers become infected when people download and open files that are malicious. Typically, cyber criminals disguise them as harmless, legitimate. Fake update tools download and install malicious programs rather than updates or they exploit bugs/flaws of outdated programs that are installed on the computer. Software 'cracking' tools are programs that supposedly bypass activation of paid software, however, they are often designed to proliferate malicious software/install malware. Trojans are malicious programs that cause chain infections - if a Trojan is already installed, it is likely to install other malware.

How to avoid installation of malware

Attachments or web links that are presented in irrelevant emails and received from unknown, suspicious addresses should not be downloaded or opened. Generally, these emails (and files attached to them) are disguised as official, important, and so on. Software should be downloaded using only direct links and trustworthy, official websites. It is not safe to use any third party downloaders, installers, or the other tools/sources mentioned above (they might be used to proliferate malware). Installed software must be updated via tools or implemented functions that are provided by official software developers. If the software is not free, it should activated properly. It is illegal to use unofficial activation tools and, furthermore, they are often designed to install malware. Have reputable anti-virus or anti-spyware software installed and scan computer with it regularly. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Update March 13, 2020 - Cyber criminals have recently started yet another Phorpiex botnet campaign. At this current moment Phorpiex is used to inject systems with XMRig cryptominer, Nemty ransomware and promote various sextortion scams. More information can be found in articles (part 1 and part 2) posted in Proof Point Research website.

To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
