To achieve persistence, the malware creates a shortcut file into the Windows startup folder named “Windows Security Update.exe.” It is started when the Windows is initiated next time.
About the malware commands, they are not the same for every victim. The commands depend on the victim’s geolocation, and the configuration is obtained from the C2 server after the language/geolocation validation.

In detail, a popular feature of this malware is the promotion of Youtube channels by watching videos and adding new comments, subscriptions, and so on.

Understanding the Electron Bot malware
Electron Bot is a new type of malware that takes advantage of victims’ machines to promote social media applications by watching videos and adding new comments and subscriptions. Although this malware doesn’t put the compromised users’ machines at risk, it is important to be aware of its features. In this sense, defensive software such as EDR and antivirus is a rule of thumb to fight these kinds of threads. The download of applications with a few reviews should be avoided as well, as criminals have used suspicious applications that impersonate legitimate ones to lure victims.
Let’s take malware protection seriously and be aware of the emerging threats that have evolved in recent months.
