Browser-maker urges web developers to take action against vulnerability that continues to haunt the industry UPDATED Three years after the infamous Spectre vulnerability was discovered, hackers can still exploit the security flaw in order to force web browsers to leak information, Google’s security team warns. The problem has arisen despite extensive efforts by browser developers to harden their software against Spectre-style attacks. The results of the research was published on the Google Security Blog on Friday (March 12) and include a proof-of-concept exploit written in JavaScript that still works against several browsers, operating systems, and processors. The key lesson from the research is that Spectre still haunts the industry – so developers need to deploy application-level mitigation measures in order to guard against potential attacks.
