RAMNIT malware is notorious for infecting Windows executable/s, Microsoft Office and Hypertext Markup Language (HTML) files. It is known to steal user names, passwords, browser cookies and will also allow hackers to take control of the infected computer. Yet another disturbing quirk of RAMNIT is that it keeps on replicating itself without the need to be attached to an existing program. In a nutshell, the RAMNIT is known to spread across the internet rapidly.
RAMNIT malware executes once a user accesses the website in which it is hosted, after which it drops and executes, a malware which is notable for having high damage potential with both backdoor and information theft capabilities. Said malware then uses command and control (C&C) communication to receive remote commands and send information such as stolen cookies and sensitive account data. It also injects malicious codes into bank webpages in order to access confidential client information from unsuspecting victims.
Furthermore, RAMNIT proves itself to be a stubborn malware by injecting itself into all running processes to remain memory-resident and deleting anti-virus related registry keys to make it undetectable.
RAMNIT’s ability to evolve and spread is a key factor to its prevalence. It was a worm that propagated through removable drives and File Transfer Protocol (FTP) servers. Cyber criminals have also expanded the malware’s capabilities by adding features such as web injection mechanisms, allowing it to compromise the websites of financial organizations or serves as banking trojan that stole user credentials and other personal information.
RAMNIT’s proliferation can be attributed to its wide variety of distribution channels, which includes traditional phishing scams such as email spam and social engineering attacks. As an infector, RAMNIT can easily spread to new victims who are unable to clean up the infected files, making them prone to reinfection.
This infection is designed to create havoc in the victims computer with multiple effects ranging from showing annoying messages and advertisements to disastrous effects like slow and sluggish performance.
