Google Patches Chrome Bug That Lets Attackers Steal Web Secrets Via Audio Or Video HTML Tags (bleepingcomputer.com)
An anonymous reader writes: "Google has patched a vulnerability in the Chrome browser that allows an attacker to retrieve sensitive information from other sites via audio or video HTML tags," reports Bleeping Computer. The attack breaks CORS -- Cross-Origin Resource Sharing, a browser security feature that prevents sites from loading resources from other websites -- and will attempt to load resources (some of which can reveal information about users) inside audio and video HTML tags. During tests, a researcher retrieved age and gender information from Facebook users, but another researcher says the bug can be also used to retrieve data from corporate backends or private APIs. Ron Masas, a security researcher with Imperva, first discovered and reported this issue to Google. The bug was fixed at the end of July with the release of Chrome v68.0.3440.75. -
Antivirus Software Performs Poorly Against New Threats
Hugh Pickens writes "Nicole Perlroth reports in the NY Times that the antivirus industry has a dirty little secret: antivirus products are not very good at stopping new viruses. Researchers collected and analyzed 82 new computer viruses and put them up against more than 40 antivirus products, made by top companies like Microsoft, Symantec, McAfee and Kaspersky Lab and found that the initial detection rate was less than 5 percent (PDF). 'The bad guys are always trying to be a step ahead,' says Matthew D. Howard, who previously set up the security strategy at Cisco Systems. 'And it doesn't take a lot to be a step ahead.' Part of the problem is that antivirus products are inherently reactive. Just as medical researchers have to study a virus before they can create a vaccine, antivirus makers must capture a computer virus, take it apart and identify its 'signature' — unique signs in its code — before they can write a program that removes it. That process can take as little as a few hours or as long as several years. In May, researchers at Kaspersky Lab discovered Flame, a complex piece of malware that had been stealing data from computers for an estimated five years. 'The traditional signature-based method of detecting malware is not keeping up,' says Phil Hochmuth. Now the thinking goes that if it is no longer possible to block everything that is bad, then the security companies of the future will be the ones whose software can spot unusual behavior and clean up systems once they have been breached. 'The bad guys are getting worse,' says Howard. 'Antivirus helps filter down the problem, but the next big security company will be the one that offers a comprehensive solution.'" -
Compromised Government and Military Sites For Sale
Khopesh writes "Imperva blogged today about the sale of compromised .gov, .mil, and .edu sites, illustrating that cyber-criminals are getting bolder. Krebs on Security has an unredacted view of the site list. Perhaps the biggest threat is yet to come; if an industrious criminal can break into top government and military sites, so too can government-backed teams, proving that GhostNet and Stuxnet are just the beginning."
