    • Scope of influence: Windows 7x64 and Windows Server 2008 R2
    • Official introduction: MS17-010  
    • Vulnerability information: Microsoft's Windows 7x64 and Windows Server 2008 R2 security patches in January and February 2018 were found to have serious vulnerabilities (TotalMeltdown). In the patch, PML4 permissions were incorrectly set to the user level, resulting in any user-mode process that can be targeted The system kernel performs arbitrary read and write.

  • WinRAR vulnerability

    2019/2/21

    • Danger level: serious
    • Danger performance: bypassing system permissions, implanting malicious files, and the computer is 'fully controlled'
    • Scope of influence: Computers with WinRAR installed, covering all systems
    • Vulnerability information: A serious security vulnerability has been found in the UNACEV2.dll code base of WinRAR. Hackers can use this vulnerability to bypass the permission prompt and run WinRAR directly, and put malicious files into the startup folder of the Windows system. As long as the user reboots the malicious files, By running automatically, hackers can 'completely control' the victim's computer, and more than 500 million users worldwide have been affected.

  • Double kill vulnerability

    2018/4/18

    • Danger level: high risk
    • Danger performance: Use 0day vulnerability to carry out APT attacks on IE kernel browser and office.
    • Scope of influence: the latest version of IE browser and applications that use IE core
    • Official introduction: CVE-2018-8174  
    • Vulnerability information: The 0day vulnerability uses multiple UAFs to complete type confusion, completes arbitrary address reading and writing by forging an array object, and finally obtains code execution by constructing the object and releasing it. Code execution does not use traditional ROP or GodMod, but uses script layout Shellcode for stable use.
