It affects productivity, preventing tasks from being carried out:
- In the affected computer:
causes system slowdowns.
- In the local network:
it generates a large amount of network activity and consumes bandwidth.
It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level; it notifies the attacker that the computer has been compromised and is ready to be used maliciously; it opens one or more ports to allow remote access to the computer and takes action that compromises user confidentiality; it changes system permissions, decreasing the security level.
It uses stealth techniques to avoid being detected by the user:
- It uses several third-party rootkits to hide the items it introduces on the affected computer.
Alanchum.AS uses the following propagation or distribution methods:
- Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
- It is dropped or downloaded to the computer by other malware specimens, for example: Gagar.K.
