BofA ‘Online Banking Passcode Reset’ themed emails serve client-side exploits and malware

Relying on bogus “Online Banking Passcode Changed” notifications and professionally looking email templates, the campaign is the latest indication of the systematic rotation of impersonated brands in an attempt to cover as many market segments as possible.
