For the past several days security researchers have raced to demonstrate that phishing protections added by a new Google Chrome extension can be bypassed with ease.The Password Alert extension, developed by Google and released Wednesday, is designed to alert Chrome users when they input their Gmail passwords on websites that don\u2019t belong to Google and are therefore part of phishing attacks.By Thursday, an information security consultant named Paul Moore had already devised a method that attackers could use to block the extension\u2019s alerts.Google fixed that initial bypass in a new version released Friday, but since then it\u2019s been a cat and mouse game between Google\u2019s developers and security researchers who kept finding more and more ways to defeat the extension.At the moment, the tally stands at nine bypasses, the latest of which was developed by Moore today. According to the researcher, only three of them have been patched by Google so far. The extension\u2019s latest version\u20141.6\u2014was released Friday.The majority of these exploits can be resolved easily, but a couple are difficult, if not impossible, to fix, Moore said Monday via email.For example, an exploit developed by researchers from Dutch software security company Securify works by sandboxing an IFRAME.\u201cI can\u2019t see how Securify\u2019s sandbox exploit can be resolved without nullifying the sandbox completely,\u201d Moore said. \u201cLikewise, my \u2018refresh on keypress\u2019 bypass works by exploiting a race condition which an extension probably cannot resolve.\u201dIn response to these exploits, the head of the webspam team at Google, Matt Cutts, commented on Twitter that: \u201cA world in which every single phisher in the world has to play catchup\/counterattack is a better world than today.\u201dWhile that might be true, it\u2019s also a bit disingenuous, Moore said. \u201cThese exploits, some of which are downright comical, put the user at a disadvantage, not the attacker.\u201dThe extension will protect against the simplest phishing attacks and for that Google should be commended, but it arguably offers little protection against more sophisticated attacks and \u201cno security is better than a false sense of security,\u201d the researcher said.
