Saefko is considered to be a RAT or, in other words, a Remote Access Trojan. Such malware makes it possible for cybercriminals to monitor and control an infected computer or a network. Many users who receive such threats get tricked into launching them. More information about the malicious application’s distribution is provided further in this article, so if you wish to learn more about this Trojan, we encourage you to read the rest of this report. Another important topic we discuss in the text is the malware’s removal. More experienced users could try to get rid of Saefko manually, but since it is a dangerous threat, our specialists recommend employing a reliable antimalware tool to be safe. Also, victims of this RAT infection ought to know that it can settle in various removable media devices, which means they ought to be checked and cleaned just like the infected computers.
The first thing we wish to discuss is the malicious application's distribution channels. Our researchers say its creators could use a few different channels, such as malicious file-sharing sites, Spam emails, and pop-up advertisements. As for the content that could contain the malware’s launcher, it could be different. For example, malicious emails could carry files that look like invoices or other harmless-looking data. As for unreliable file-sharing sites and ads, such channels could offer malicious software or game installers that might be bundled with Saefko as well as other threats. Therefore, to avoid similar malicious applications, we advise being careful with emails from unknown senders or messages that carry data you did not expect to receive. Also, it is best to stay away from untrustworthy file-sharing web pages that offer pirated software, unknown freeware, etc. Of course, having a reliable antimalware tool on your system could help you keep it secure too.
If Saefko gets in it should create randomly named files in the directories that are listed in our deletion instructions, which are located below this article. All the time that the malicious application stays on the system, it ought to launch itself upon each restart. Since it works in the background, victims might not notice the malware being on their computers. One of the things the Trojan is capable of is collecting various information, such as browsing history related to social media websites, payment platforms, cryptocurrencies, gaming, shopping, and so on. In other words, the malware’s developers are interested in browsing history that could reveal sensitive information. Unfortunately, the threat is capable of much more as it can also access files available on the infected device, take screenshots, film videos while using an infected computer’s camera, as well as recording users’ keystrokes to gather passwords and other sensitive information.
Moreover, if a removable drive is inserted into an infected computer, the malware should drop a few malicious files on it. To disguise such data, Saefko should change the malicious files’ titles with names that would make the data look harmless, for example, USBStart.exe. Such files could infect devices that the removable drive might be connected to next. In other words, it seems like the threat's creators may have found a way to make their victims spread Saefko unknowingly themselves.
Thus, the malware's victims must remove Saefko not only from their computers but also from devices that they may have inserted into the infected machine. The instructions available below show how one could erase the RAT infection manually, but we do not recommend doing it if you are an inexperienced user. Trojans are serious threats that can be difficult to remove, which is why we advise using a reliable security tool that could deal with Saefko for you.
