Most Valued Members peteyt 285 Posted August 18, 2017 Most Valued Members Share Posted August 18, 2017 I'm writing a kind of security guide and looking into antivirus/basic security. I know a friend of mine used to avoid using any antivirus and just stuck to safe sites, using adblockers to avoid possible malware hidden in adverts. However I never liked that, always thought it was putting too much trust in something. So I am wondering if it is actually possible for these types of malware to bypass adblockers?

Most Valued Members cyberhash 158 Posted August 18, 2017 Most Valued Members Share Posted August 18, 2017 Well adblockers work by using "lists" of known ad sites and don't employ anything clever in the way of detection/blocking. Link to comment Share on other sites More sharing options...
itman 1,363 Posted August 18, 2017 Share Posted August 18, 2017 UBlock Origin is probably the most extensive one with a lot of customization features: https://github.com/gorhill/uBlock Works with FireFox, Chrome, and Edge. Not available for IE. However, your friend "is kidding himself" if he sincerely believes this type of protection alone is sufficient. Link to comment Share on other sites More sharing options...

Actually just found this https://securityintelligence.com/news/malvertising-scheme-bypasses-ad-blockers/ Quote Attackers are performing redirections using dynamically created scripts to subvert ad blockers, according to the report. The script gets its data from a different URL every day, which makes URL blocking difficult. Users of Adblock Plus, uBlock Origin and AdGuard have reported malvertising getting through the blockers, the researchers said. Link to comment Share on other sites More sharing options...
Administrators Marcos 4,191 Posted August 19, 2017 Administrators Share Posted August 19, 2017 It's important to realize that even with the best ad blocker users won't be 100% safe. For instance, popular websites may get compromised at times and may serve malware, either as iframe, script, external script or the attacker will replace otherwise perfectly legit app like a remote admin tool, torrent client, etc. with a trojanized one which also contains malware besides the legitimate application.

0xDEADBEEF 43 Posted August 19, 2017 Share Posted August 19, 2017 (edited) Isn't relying on adblock for safety similar to relying on some AVs which purely based on hash/fuzzy-hash blacklisting? Besides, simple anti-adblock tricks and some social engineering can easily bypass this, if the user is not "cautious enough" Edited August 19, 2017 by 0xDEADBEEF Link to comment Share on other sites More sharing options...
