Inventors:

Michael Greene - Boulder CO, US
Matt Parker - Broomfield CO, US

International Classification:

G06F 12/14

US Classification:

726022000

Abstract:

A method and system for detecting a keylogger that encrypts data captured on a computer. One illustrative embodiment acquires a first sample of a portion of a memory of a computer, the portion of the memory being associated with a running process on the computer; inputs to the computer, in a manner that mimics keyboard input, a first data pattern consisting of at least one occurrence of each of a first set of distinct sub-patterns; acquires a second sample of the portion of the memory; compares the first and second samples of the portion of the memory to identify at least one data segment in which the second sample has changed relative to the first sample; and flags the running process as a potential keylogger when the at least one data segment contains a second data pattern matching the overall sub-pattern structure of the first data pattern despite the particular sub-patterns making up the first and second data patterns being different.

Abstract:

A method and system for removing pestware from a computer is described. One illustrative embodiment detects that pestware is present on a computer, automatically suspends connectivity of the computer with a network, and removes the pestware from the computer while the connectivity of the computer with the network is suspended. This prevents the pestware from downloading additional pestware from the network in response to a removal attempt.
