A new and unique virus has been identified to be “spreading widely” in the Indian cyber space which often sensibly steals bank account data in addition to passwords associated with the customer after it is visited.
Country’s online reliability sleuths have informed Internet users in the country about the new and suspected variant of malware/worm genre called ‘Win32/Ramnit’.
“Ramnit worm spreads by infecting or modifying files existing on target systems such as (EXE, dll or html) and creating a new section so as to modify the entry point to that section,” an advisory issued by country’s premier cyber security agency – Computer Emergency Response Team-India (CERT-In) – said.
The malware, the advisory states, “steals credentials like file transfer protocol passwords, bank account logins, infects removable media, changes browser settings and downloads and executes arbitrary files”.
The virus is so deadly and potent, cyber sleuths say, that it has ability to hide itself from anti-virus solutions and acquires various aliases to attack a genuine system or
Internet-based connection which works to play emails and other user services.
The virus is such lethal in its operations that it “infects the removable media by copying itself to its recycle bin and creates an autorun.inf file,” the advisory said.
Once the system is infected, the malware injects its code into windows executables, html files or dlls to communicate with its command and control server, thereby compromising the security of the online system.
The agency has also advised some counter measures in this regard.
How to tackle Ramnit–Do not download programs or files from unknown websites
–Do not click links in emails received from unknown sources
–Do not download attachments in emails received from unknown sources
–Use a firewall and anti-virus. If you don’t want to pay for such programs Microsoft Security Essential or Avira anti-virus are very good alternatives
–Disable auto-run for pen drives and portable harddisks
–Keep your operating system updated
–Use the latest version of your web browser
–Don’t use pirated software
–If you feel your computer has been infected, update your anti-virus, disconnect internet and run a thorough virus scan
