![]() ![]() Very simply put, in an SEH attack, a malicious hacker makes a targeted application - such as Yahoo Media Player - fail. An Ethical Hacker blog post showcases an SEH exploit of Yahoo Media Player. First introduced in Windows Vista SP1, this technology is designed to protect systems from vulnerabilities that exploit Structured Exception Handler (SEH) overwrite vulnerabilities (as detailed in MS Support article 956607). Installing EMET will back-port some of the new security technologies found in Windows 7.įor example, EMET will add Structured Exception Handling Overwrite Protection (SEHOP more info) to Windows XP. Natively, Windows XP can’t opt into additional AV protection. Windows XP users should also know that EMET is not as effective on that OS as it is on Vista and Windows 7. NET 2.0 Service Pack 1 at its MS Download Center page. NET 2.0, if you’ve not already done so.) You can get. (EMET 3.5’s installation process will prompt you to download and install. NET Framework 2.0 loaded onto your system. If you’re still on Windows XP, there’s a bit of bad news. As with all AV tools, Microsoft is constantly enhancing EMET and recently released Version 3.5 (Download Center page), which adds four new types of virus-mitigation tools. Microsoft Support article 2458544 explains EMET in detail. It won’t guarantee protection from all vulnerabilities, but it makes it much harder for a cyber criminal to attack you. Simply put, EMET can provide an extra layer of protection until there’s an official patch for a new exploit. For advanced PC users, I also recommend downloading and using the Enhanced Mitigation Experience Toolkit (EMET). Exploits typically use one specific browser or add-on application such as Java or Adobe Flash. One form of protection I’ve recommended is to use multiple browsers and keep them up to date. Those as-yet unpatched threats are called zero-day exploits, and they’re a constant menace to safe computing. ![]() When hackers create new forms of malware, there’s a (hopefully brief) time during which PCs are open to attack while antivirus companies build and deliver a virus-definition update. Minimizing the threat from zero-day exploits One of the better tools for protecting our systems from the new threats is Microsoft’s oddly named Enhanced Mitigation Experience Toolkit. These signatures are the rules used by the security program to identify malicious software.TOP STORY Protecting PCs from the next zero-day threatįor every zero-day vulnerability we patch, there’s another waiting in the wings - and yet another, no doubt. Typically, false positives can be fixed by updating the signature files in security applications. During testing, OneCare was found to disable Absolute Software's Computrace LoJack, an application that functions like a homing device to help recover a laptop after it has been lost or stolen. The Gmail issue isn't the first problem it has had. Windows Live OneCare is Microsoft's first consumer antivirus product, released late May. ![]() Also, Symantec this summer identified a Church of England software program as spyware. For example, McAfee's security tools earlier this year flagged Microsoft's Excel, and other legitimate applications on users' PCs, as viruses. Google did not immediately respond to a request for comment.įalse positives happen occasionally with security software. The software maker is reviewing its procedures and processes in order to minimize the occurrence of further false positives, the Microsoft representative said. The problem started last week, when Google made some changes to its Gmail Web site, Microsoft said. ![]()
