A system, method, and computer program product are provided for redirecting internet relay chat (IRC) traffic identified utilizing a port-independent algorithm and controlling IRC based malware. In use, IRC traffic communicated via a network is identified utilizing a port-independent algorithm. Furthermore, the IRC traffic is redirected to a honeypot.

A method for detecting removal of a filter driver includes performing an operation on an element of a kernel mode of an operating system, the operation initiated by a user mode entity, obtaining the result of performing the operation, and comparing the result of performing the operation against an expected result of the operation. If the result of performing the operation matches the expected result of the operation, it is determined that a file system filter driver in the kernel mode of the operating system is working correctly. If the result of performing the operation does not match the expected result of the operation, it is determined that a file system filter driver in the kernel mode of the operating system has been compromised by malware.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for obfuscated malware. In one aspect, a method includes executing from a binary executable a call instruction and a plurality of instruction subsequent to a target of the call instruction, determining if the value identified by the stack pointer of the call stack is equal to a default value stored in the call stack prior to emulation, determining if there is a non-obfuscation signal resulting from the execution of the call instructions and the plurality of instructions, and if the value identified by the stack pointer is the default value and there is no obfuscation signal, identifying the call instruction as a possibly obfuscated call instruction; Additionally, the method includes determining that if the number of call instructions identified as possibly obfuscated call instructions exceeds a threshold number, identifying the binary executable as an obfuscated executable.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting obfuscated malware. In one aspect, a method includes identifying call instructions in a binary executable; executing the call instruction; executing instructions subsequent to a target of the call instruction; determining that an address identified by a stack pointer is different from the return address; in response to the determination that the address is different, determining if there is a non-obfuscation signal; if there is a non-obfuscation signal, identifying the call instruction as a non-obfuscated call instruction; if there is not a non-obfuscation signal, identifying the call instruction as a possibly obfuscated call instruction; determining whether the call instructions identified as possibly obfuscated call instructions exceeds a threshold; in response to the determination that the call instructions identified as possibly obfuscated call instructions exceeds the threshold, identifying the executable as an obfuscated executable.

摘要:
A system, method, and computer program product are provided for applying a regular expression to content based on required strings of the regular expression. In use, all required strings included in a regular expression are identified, the required strings including strings required by the regular expression. Additionally, it is determined whether the required strings match content. Furthermore, the regular expression is applied to the content, based on the determination.

Provided in some embodiments are systems and methods for remediating malware. Embodiments include receiving (from a process) a request to access data, determining that the process is an unknown process, providing the process with access to one or more data tokens in response to determining that the process is an unknown process, determining whether the process is engaging in suspicious activity with the one or more data tokens, and inhibiting execution of the process in response to determining that the process is engaging in suspicious activity with the one or more data tokens.
