Attacks Against Computer Forensics
In the past anti-forensic tools have focused on attacking the forensic process by destroying data, hiding data, or altering data usage information. Anti-forensics has recently moved into a new realm where tools and techniques are focused on attacking forensic tools that perform the examinations. These new anti-forensic methods have benefited from a number of factors to include well documented forensic examination procedures, widely known forensic tool vulnerabilities and digital forensic examiners heavy reliance on their tools.
During a typical forensic examination, the examiner would create an image of the computer's disks. This keeps the original computer (evidence) from being tainted by forensic tools. Hashes are created by the forensic examination software to verify the integrity of the image. One of the recent anti-tool techniques targets the integrity of the hash that is created to verify the image. By affecting the integrity of the hash, any evidence that is collected during the subsequent investigation can be challenged.

Famous quotes containing the words attacks and/or computer:
“We are supposed to be the children of Seth; but Seth is too much of an effete nonentity to deserve ancestral regard. No, we are the sons of Cain, and with violence can be associated the attacks on sound, stone, wood and metal that produced civilisation.”
—Anthony Burgess (b. 1917)
“What, then, is the basic difference between todays computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of patterna capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
