Winter Sochi Olympics, Comments from David Grange Dyn

As we commence the opening of the winter Olympics tomorrow and given the heightened interest this year, this is also a prime opportunity for cybercriminals to exploit the security of the games online using phishing attacks and sending harmful emails.

David Grange, director of operations and client services (EMEA) at Dyn offers his comments on the subject.

“The spike in interest around the Winter Olympics offers a prime opportunity for cybercriminals targeting users with phishing attacks – and making businesses an easy target. More than 144 billion emails are sent every day with a large portion of those being vital transactional emails sent from businesses across the world. By sending emails pretending to be event updates and insight, cyber criminals capitalise on the widespread interest in the Winter Olympics to inject malware or malicious downloads onto company servers. The only way to know whether the emails in employees’ inboxes are coming from a verified sender is to use DNS. While traditionally, DNS is associated with keeping websites performing fast and preventing downtime, DMARC offers up a new way of authenticating email delivery by using the DNS. If the email that arrives does not pass this validation process, the receiver then knows to junk or reject the email, avoiding harmful messages. This method eliminates the guesswork and ensures every step along the email delivery chain is secured.”

To avoid becoming the victim of an Olympic phishing scam, David recommends that businesses should consider:

·  Advising their employees to check links before clicking by hovering over them, or holding them down for a few seconds on smartphones

·  Encouraging employees to go websites directly in their web browser rather than clicking a link from a suspicious email

·  Evaluating their email security and consider strengthening their defences with technologies such as SPF, DKIM and DMARC
