A team of security researchers from Cybellum, an Israeli zero-day prevention firm, has discovered a new Windows vulnerability that could allow hackers to take full control of your computer. Dubbed DoubleAgent , the new injecting code technique works on all versions of Microsoft Windows operating systems, starting from Windows XP to the latest release of Windows 10. What's worse? DoubleAgent exploits a 15-years-old undocumented legitimate feature of Windows called " Application Verifier ," which cannot be patched. Application Verifier is a runtime verification tool that loads DLLs (dynamic link library) into processes for testing purpose, allowing developers quickly detect and fix programming errors in their applications. Unpatchable Microsoft Application Verifier Exploit The vulnerability resides in how this Application Verifier tool handles DLLs. According to the researchers, as part of the process, DLLs are bound to the target processes in a Windows Regist...

Are you curiously googling or searching torrents for photos or videos of Emma Watson, Amanda Seyfried, Rose McGowan, or any other celebrities leaked in The Fappenning 2.0 ? If yes, then beware, you should not click any link promising Fappenning celebrity photos . Cybercriminals often take advantage of news headlines in order to trap victims and trick them into following links that may lead to websites containing malware or survey scams. Last week, a few private photos of Emma Watson and Amanda Seyfried — ranging from regular selfies to explicitly sexual photos — were circulating on the Internet forums, including Reddit and 4chan, with UK's TV presenter Holly Willoughby and US actor Rose McGowan among the latest alleged victims. Now, according to the security researchers from MalwareBytes, scammers are exploiting this new batch of leaked celebrity photos and videos by using their stolen selfies to lure victims on social media sites and making dollars.

You may be aware of the fact that a local Windows user with system rights and permissions can reset the password for other users, but did you know that a local user can also hijack other users' session, including domain admin/system user, without knowing their passwords? Alexander Korznikov, an Israeli security researcher, has recently demonstrated that a local privileged user can even hijack the session of any logged-in Windows user who has higher privileges without knowing that user's password, using built-in command line tools. This trick works on almost all versions of Windows operating system and does not require any special privileges. Korznikov is himself unable to figure out if it is a Windows feature or a security flaw. The issue discovered by Korznikov is not entirely new, as a French security researcher, namely Benjamin Delpy, detailed a similar user session hijacking technique on his blog some six years ago. Korznikov calls the attack a "privilege ...

You might have heard the latest news about Microsoft blocking new security patches and updates for Windows 7 and Windows 8.1 users running the latest processors from Intel, AMD, Qualcomm, and others. Don't panic, this new policy doesn't mean that all Windows 7 and 8.1 users will not be able to receive latest updates in general because Microsoft has promised to support Windows 7 until 2020 , and Windows 8.1 until 2023. But those who have upgraded their machines running older versions of Windows to the latest processors, or manually downgraded their new laptops to run Windows 7/8.1 would be out of luck. A recently published Microsoft Knowledge Base article suggests that if you are running the older version of operating systems on your computers that feature new processors, including Intel's 7th generation Core i3, i5 and i7 ("Kaby Lake"), AMD Ryzen ("Bristol Ridge") and Qualcomm 8996 chips or later, the security updates will not install. Inste...

Cisco is warning of a new critical zero-day IOS / IOS XE vulnerability that affects more than 300 of its switch models. The company identified this highest level of vulnerability in its product while analyzing " Vault 7 " — a roughly 8,761 documents and files leaked by Wikileaks last week, claiming to detail hacking tools and tactics of the Central Intelligence Agency (CIA). The vulnerability resides in the Cluster Management Protocol (CMP) processing code in Cisco IOS and Cisco IOS XE Software. If exploited, the flaw ( CVE-2017-3881 ) could allow an unauthenticated, remote attacker to cause a reboot of an affected device or remotely execute malicious code on the device with elevated privileges to take full control of the device, Cisco says in its  advisory . The CMP protocol has been designed to pass around information about switch clusters between cluster members using Telnet or SSH. The vulnerability is in the default configuration of affected Cisco devices,...
