What is Osiris?

Osiris is an updated variant of a high-risk trojan called Kronos. This malware records various personal information and modifies the content of visited websites. The presence of this infection on your system can lead to many issues.

Osiris malware

The main purpose of Osiris is to gather information. The list of Osiris features includes keylogging - it records and saves all keystrokes. Furthermore, it collects information from browsers (Internet Explorer, Google Chrome, Mozilla Firefox) and the Microsoft Outlook email client. It gathers account credentials. Note also the use of the so-called "man-in-the-browser" technique, which is used to exploit browser bugs and vulnerabilities to change the content of visited websites. Criminals typically use this technique to gather logins/passwords entered on various websites (especially, banks). The combination of keylogging and data-stealing functionalities can cause serious issues. Cyber criminals aim to generate as much revenue as possible. Therefore, there is a high probability that they will misuse hijacked accounts in various ways (e.g., via money transfers, online purchases, money borrowing from contacts, privacy theft, etc.). The presence of Osiris might cause serious privacy issues and significant financial loss.

There are many trojan-type infections that share similarities including, for example, Bolik, Chthonic, and REDAMAN. As well as tracking data, some infections of this type cause "chain infections" (trojans proliferate other infections). Therefore, the presence of this malware can lead to further system infections (e.g., ransomware, cryptominers, etc.). Eliminate all trojan infections immediately.

How did Osiris infiltrate my computer?

Be aware that developers sell Osiris as a service on hacker forums. Therefore, any aspiring cyber criminal can purchase the Osiris executable and start stealing information. It is difficult to determine the exact way in which Osiris is distributed (since anyone can proliferate it using different tools/methods), however, these trojans are typically proliferated using spam email campaigns, fake software updaters/cracks, other trojans, and unofficial software download sources. Spam campaigns are used to send hundreds of thousands of emails that contain malicious attachments (links/files) and messages encouraging users to open them. In most cases, attachments are presented as important documents (e.g., invoices, receipts, bills, etc.) in attempts to give the impression of legitimacy. Fake update tools typically infect computers by exploiting existing software bugs/flaws or simply downloading and installing malware rather than promised updates. Cracks have similar behavior. Although the idea behind software cracking tools is to activate paid software free of charge, criminals often use them to proliferate malware. Therefore, users are much more likely to infect their computers than gain access to paid features. As mentioned above, some trojan-type viruses cause "chain infections", and thus they infiltrate the system and inject it with additional malware. Finally, third party software download sources are used by criminals to present malicious executables as legitimate software. In this way, users are tricked into downloading and installing malware rather than updates. In summary, the main reasons for computer infections are poor knowledge of these threats and careless behavior.

How to avoid installation of malware?

To prevent this situation, be very cautious when browsing the internet and downloading, installing, and updating software. Manage all received email attachments with care. Do not open anything received from suspicious/unrecognizable email addresses, or if the sender seems suspicious. Furthermore, avoid using third party downloaders/installers. Software should be downloaded from official sources only, preferably using direct download links. The same applies to software updates. It is important to keep installed applications up-to-date, however, this should be achieved only through implemented functions or tools provided by the official developer. Software piracy is a cyber crime and the risk of infections is extremely high. Therefore, never attempt to crack installed applications. Finally, have a reputable anti-virus/anti-spyware suite installed and running at all times. These tools are capable of detecting and eliminating most computer infections before they harm the system. The key to computer safety is caution. If you believe that your computer is already infected, we recommend running a scan with Spyhunter 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".

locate the malware file you want to remove

After removing the malware through 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 Spyhunter for Windows.
