Removal instructions for the Jorik trojan-type malware

Also Known As: Jorik malware
Type: Trojan
Damage level: Severe

What kind of malware is Jorik?

Jorik is the name of a trojan-type malware. This program stealthily infiltrates victims' machines on which it can then perform malicious actions. Trojans are considered to be high-risk threats – hence, they must be eliminated from operating systems immediately upon detection.

Jorik malware overview

Following successful infiltration, Jorik decrypts a file contained within itself and dumps it into a temporary folder. This content is then used to establish contact with the cyber criminals' C&C (Command and Control) server. Once connected, the trojan can then retrieve files from its C&C.

Technically, malware capable of downloading/installing additional malicious programs or components can cause just about any type of infection (e.g., ransomware, trojan, cryptominer, etc.). However, most programs operate within certain limitations, i.e., only inject malicious code, install specific modules, or infiltrate particular malware.

Jorik's modus operandi is currently unknown. The most common malware infections are geared towards data theft. There are programs capable of exfiltrating files and/or extracting information from installed applications.

Targeted data typically includes: browsing activity, Internet cookies, usernames/passwords, personally identifiable details, and finance-related data (e.g., banking account details, credit card numbers, etc.). Keylogging (i.e., keystroke logging) and recording audio/video via microphones and cameras – are prevalent capabilities amongst information-stealing trojans.

However, malware can be highly versatile and have different functionalities in varied combinations. Furthermore, developers of malicious software often improve upon their creations – hence, potential future iterations of Jorik could boast additional/different abilities and features.

In summary, the presence of high-risk malware on devices can result in multiple system infections, diminished system performance or failure, data loss, severe privacy issues, financial losses, and identity theft.

If you suspect that your device is infected with Jorik (or other malware) – we strongly recommend running a full system scan with an anti-virus and eliminating all detected threats without delay.

Malware in general

We have researched thousands of malware samples; XWorm RATWikiLoaderFruity trojan, and RATRUN stealer are just a couple of our newest articles on this topic.

As previously mentioned, malicious software can have a wide variety of capabilities that can be in different combinations. The threats posed by an infection entirely depend on the malware's functionalities and the cyber criminals' goals. However, regardless of how this software operates – its presence on a system endangers device integrity and user safety.

How did Jorik infiltrate my computer?

Malware is predominantly spread using phishing and social engineering techniques. The most widely utilized distribution methods include: drive-by (stealthy/deceptive) downloads, malicious attachments and links in spam emails/messages, untrustworthy download sources (e.g., freeware and third-party sites, Peer-to-Peer sharing networks, etc.), online scams, malvertising, illegal program activation tools ("cracks"), and fake updates.

Furthermore, some malicious programs can self-proliferate through local networks and removable storage devices (e.g., USB flash drives, external hard drives, etc.).

Malicious software is often presented as or bundled with ordinary program/media files. They can be archives (RAR, ZIP, etc.), executables (.exe, .run, etc.), documents (Microsoft Office, Microsoft OneNote, PDF, etc.), JavaScript, and so on. When an infectious file is executed, run, or otherwise opened – the malware download/installation chain is initiated.

How to avoid installation of malware?

We highly recommend being careful while browsing since fake and dangerous online content usually appears legitimate and harmless. Another recommendation is to be cautious with incoming emails, PMs/DMs, SMSes, and other messages. Attachments or links found in suspicious mail must not be opened, as they can be malicious.

Furthermore, all downloads must be performed from official and verified sources. We advise activating and updating software by using legitimate functions/tools, as illegal activation ("cracking") tools and third-party updates can contain malware.

It is paramount to have a reputable anti-virus installed and kept up-to-date. Security programs must be used to perform regular system scans and to remove threats and issues. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

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".

Delete malware in Autoruns

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.

Search for malware and delete it

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 Combo Cleaner Antivirus for Windows.
