ByteVerify is a hacking tool that allows an attacker to run malicious code by exploiting avulnerability in Microsoft Virtual Machine(Microsoft VM). This virtual machine incorporates a component that checks for malicious code when a Java Applet is loaded. However, due to this vulnerability, the component does not perform this check, and therefore an attacker could run a malicious Java Applet when a user visits a web page that contains it. The virtual machine is included in Windows XP/2000 Pro/NT/Me/98/95, and in different version of Internet Explorer. This vulnerability has already been fixed in some versions of these products. However, it is highly recommendable to update the Microsoft Virtual Machine. Click here to access the web page for information on the vulnerability and fixing it. This vulnerability is exploited by some worms such as JS/Fortnight.E. |
