Websense® Security Labs™ ThreatSeeker™ Network has discovered a new wave of malicious attacks claiming to be an update for Microsoft Outlook Web Access (OWA). Victims receive a message leading to a site to apply mailbox settings which were supposedly changed due to a "security upgrade." The especially dangerous thing about these messages is that they are very deceiving. The messages and attack pages are personalized for the To: email address to imply the message is being sent from tech support of the domain. The URL in the email looks like it leads to the company's own OWA system. We have seen upwards of 30,000 of these messages per hour and they have low AV detection. MORE
