Risk: Low
A worrying new potential Trojan called DNSChanger.eg can redirect website visitors to fake financial sites, even if they type in the correct URL.
DNSChanger.eg works by corrupting the process of translating a domain name into the actual website. When a user types in the web address of a financial institution, it is translated into a string of numerical information. The Trojan changes the NameServer Registry key to a fraudulent IP address.
The Trojan hasn't been seen very widely and it may be that the fraudulent websites are identifiable as fakes by keen-eyed users - perhaps there is no https URL, or lack of a padlock.
As always, those using online banking are advised to stay vigilent and report any suspicious sites that they come across.
