Recent news reported that a lot of on-line bank customers have found discrepancies in their bank accounts, causing them to lose money unknowingly. Investigations of these incidents have proved that the customers have been attacked by Trojan horse programs.

 

A computer criminal can exploit known vulnerabilities of an unpatched computer, and then create backdoors, which allow the attacker remotely implant a Trojan horse program into the victim’s computer system.  A Trojan horse can contain a “key logger” program which logs each key press of the victim and then transmit sensitive financial data back to malicious attackers.  BroadWeb’s NetKeeper is an Active IDP (Intrusion Detection & Prevention System) which can thwart malicious attackers’ attempts to exploit known vulnerabilities of computer systems in enterprises, thus preventing attackers from installing key logger Trojan program remotely.

 

A computer criminal can also “add” a key logger program into a normal program to create a packet, and then distribute the key-logger Trojan to thousands of Victims. Anyone executing the key-logger Trojan program will be installed the key-logger unknowingly.  So BroadWeb suggests that users do not download programs from untrusted web sites, do not logon to bank web sites when using public computers, do not execute attached files in unsolicited emails, ask banks to implement fund transfer controls for your on-line bank accounts, install anti-virus programs and update regularly, and when receiving an email alleged from your banks, do not click the links provided by the email, because computer criminals may dupe users into disclosing their bank account details after they have linked to the faked bank web sites.
