Azure Phoenix 11 Posted June 20, 2018 Share Posted June 20, 2018 1- https://www.infosecurity-magazine.com/news/security-of-html5-may-not-live-up/ 2 - https://martechtoday.com/media-trust-warns-of-malware-in-html5-ads-217292?utm_src=ml&utm_medium=textlink&utm_campaign=mlxpost "One of the most problematic characteristics of the way in which HTML5 malware is delivered, Olson said, is that it is taking advantage of “obfuscated code” populating HTML5 ads. This obfuscation, he said, is “like a kind of encryption,” used by many legitimate developers to keep their software tricks from competitors. But that “makes it extremely difficult to understand” and to find the delivery mechanisms used to carry the malware." Link to comment Share on other sites More sharing options...
itman 1,595 Posted June 20, 2018 Share Posted June 20, 2018 Bunch of HTML5 tests here: https://html5sec.org/#html5 . Many would not run in IE11. I did get a SmartScreen alert from the evil.com test. Nothing from Eset but don't know if that means anything since the test shows HTML5 code used by malware w/o any actual malicious code employed.

cvvorous 4 Posted June 21, 2018 Share Posted June 21, 2018 the blog both articles refer to is really light on details beyond inferring that bad actors are using html5 redirects on mobile devices with specific criteria; my guess is that eset would protect the user from the domain a browser is redirected to. imo, the html5 "malware" referenced doesn't seem like "malware" so much as using html5 features to do sketchy stuff.

itman 1,595 Posted June 25, 2018 Share Posted June 25, 2018 HTML5 malware is not new: https://news.softpedia.com/news/html5-can-be-used-to-hide-malware-in-drive-by-download-attacks-486974.shtml . I do know that Microsoft browsers and Firefox were both recently patched to eliminate most if not all of the attack vectors. Also, Chrome has its own protection mechanisms.
