Today’s webinar: Malvertising – When trusted websites go rogue
Today, Paul Ducklin is talking to John Shier, Sophos IT Security Specialist.
Crooks don’t need to hack into a mainstream website to infect it with malware.
They can get away with hacking just one ad served up by one ad network – and some high-traffic sites take content from hundreds of different ad networks at a time.
This is “malvertising”, and it hurts the websites that get affected, the ad networks that get compromised…and the victims who get infected while surfing their usual, trusted and unexceptionable sites.
Even mainstream sites – sites that you’d never get into trouble for browsing at work, because they’re well-known sites with useful content – can fall victim to malvertising.
Indeed, this week’s news is that at least BBC, Newsweek, The New York Times and MSN were affected over the weekend.
So it it’s certainly the sort of problem that could happen to you!
John will explain how malvertising works, why crooks love it, and what we can do to stamp it out.Follow @NakedSecurity
