What is Megumin?

Megumin is a malicious software that is categorized as a trojan.

It is a high-risk computer infection that can cause its victims serious problems. It should be eliminated immediately.

Megumin malware

Megumin is available for purchase on the dark web (hacker forum), its license costs 6000 rubles. Bots, stealers and loaders cost 500 rubles per unit and the whole source code costs 60000 rubles. When installed in a computer, it places two files: the loader and the bot. The loader checks if the bot is loaded every 30 minutes. If it is not loaded, then loader launches it. Additionally, all Megumin's files are hidden and cannot be revealed. When launched, it does not have administrative rights. It allows its users (cyber criminals) to see user-system details of every infected computer, such as IP address, country, Windows version and bit depth, CPU and GPU. One of the main features of Megumin trojan is cryptocurrency mining. It operates as a miner that uses computer's CPU to solve mathematical problems (mine cryptocurrency). Another Megumin's feature is that it can perform a DDoS (distributed denial-of-service) attack. Simply said, the infected machine can be used to send a number of queries to a desired server, thereby intentionally loading it (a server attacked by multiple computers can easily crash). Another feature is information/data stealing. It steals data such as wallet.dat files that contain private key information stored by cryptocurrency clients, browser cookies and passwords from browsers such as Google Chrome, Mozilla Firefox, Opera, Yandex, Torch and Amigo. Furthermore, cyber criminals can use Megumin to execute commands on victim's computer through the Command Prompt, to search for files stored on a computer, download and launch files and upload various files from victim's computer to a server. It can also replace wallets in the clipboards. Cyber criminals can trick victims into copying wallet addresses that belong to them, which means victims would make transactions to them. To sum up, it could be used to infect computers with other malicious programs like ransomware, and other malicious software. To steal data that could be used to generate revenue and cause its victims financial loss, and to mine cryptocurrency. Crypto mining is a process that can lead to higher electricity bills, hardware overheat and decreased computer's performance. These are the main reasons to uninstall Megumin immediately.

The Internet is full of various malware. Some exmaples of other trojan-type programs are Proton Bot Loader, Hancitor and Emotet. Typically, these malicious programs are designed to spread other viruses, steal information and so on. One way or another, programs like Megumin must be uninstalled as soon as possible.

How did Megumin infiltrate my computer?

To trick other people into installing malicious programs like Megumin, cyber criminals usually use spam campaigns, untrustworthy software download sources, trojans, unofficial (fake) software updating tools and untrustworthy software activation tools. If they use spam campaigns, they send emails that contain attached files. Typically, they attach executable files, PDF documents, archive files, Microsoft Office documents, JavaScript files or some other files. If people open them, they allow for various malicious programs to be downloaded and installed. Another way to spread malware is through Peer-to-peer (P2P) networks such as torrent clients, eMule (and other similar tools), freeware download websites, file hosting websites, third party downloaders and so on. Cyber criminals upload/put their malicious files there and disguise them as some harmless files. Once downloaded and opened, malicious files infect computers with high-risk viruses. Unofficial software updating tools, if used, infect computers by downloading and installing malware instead of some software fixes, updated and so on. They could cause damage by exploiting flaws/bugs of outdated software as well. One more way to spread malicious programs is to use unofficial software activation ('cracking') tools. Typically, these tools are used with a purpose to bypass paid software activation, to avoid paying for it. However, it is known that these tools often are designed by cyber criminals who use them to distribute malware. Simply said, there are many cases where these tools download and install malicious programs.

How to avoid installation of malware?

We recommend to be careful with files or links that are presented in received emails. If an email is irrelevant and it is received from unknown or suspicious address, do not click the link or open the included attachment. Additionally, download software from official, trustworthy websites and use direct download links. We advise to avoid using various third party downloaders, unofficial pages and any other similar sources for that. Do not try to activate software with some 'cracking' tools. It is illegal and often leads to installations of malware. Keep installed software up do date, however, is is important to do it using tools or implemented functions that are provided by official software developers. Make sure that there is a reputable anti-spyware or anti-virus software installed on a computer and do not disable it without a good reason. Besides, it is a always a good idea to run a virus scan one in a while. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
