Also, it is recommended that NCB customers should never click on a link in an email message to sign into their accounts.instead, they should go directly to NCB's website at http://www.jncb.com/ and sign in from there.
Now, although the abovementioned advise will help protect NCB or other online banking customers, there is a hacking technique called "Man-in-Middle" attack, which cyber-criminals can use to harvest financial, personal or other information that they will need to rip off their victims.
To prevent the "Man-in-Middle" attack, it is recommended that online banking users never use a public computer or Wi-Fi connection, which are usually located at cybercafes, airports or hotels, to sign into their online banking accounts. They should instead use trusted internet connections like their home, work or mobile phone data internet connections.
NCB is asking its customers to call 1-888-622-3477 to report doubtful emails.
