Understanding Anti-Forensics and Their Goals

Understand Anti-forensics and their goals, also referred to as counter forensics, maybe a set of techniques that attackers or perpetrators use so as to avert or sidetrack the forensic investigation process or attempt to make it much harder. These techniques negatively impact the number and quality of evidence from a criminal offense scene, thereby making the forensic investigation process difficult. Therefore, the investigator may need to conduct a few more additional steps so as to fetch the info, thereby causing delay within the investigation process.

Goals of Anti-Forensics:

  • Interrupt and stop information collection.
  • Toughen the investigator’s task find the evidence.
  • Hide traces of crime or criminality.
  • Compromise the accuracy of a forensic report or testimony.
  • Force the forensic tool to reveal its presence.
  • Use a forensic tool itself for attack purposes.
  • Delete evidence that an anti-forensic tool has been used.

Anti-forensics are often a computer investigator’s worst nightmare. Programmers design anti-forensic tools to form it hard or impossible to retrieve information during an investigation. Essentially, anti-forensics refer to any technique, gadget, or software designed to hamper a computer investigation.

There are dozens of the way people can hide information. Some programs can fool computers by changing the knowledge in files’ headers. A file header is generally invisible to humans, but it’s extremely important — it tells the pc what quiet file the header is attached to. If you were to rename an mp3 file in order that it had a .gif extension, the pc would still know the file was really an mp3 due to the knowledge within the header. Some programs allow you to change the knowledge within the header in order that the pc thinks it is a different quite file. Detectives trying to find a selected file format could jump important evidence because it seemed like it wasn’t relevant.

Digital forensics is employed in both criminal and personal investigations. Traditionally, it’s related to legal code where evidence is collected to support or negate a hypothesis before the court. Collected evidence could also be used as a part of intelligence gathering or to locate, identify, or halt other crimes.

Digital forensics, sometimes called computer forensics, is that the application of scientific investigatory techniques to digital crimes and attacks. It’s an important aspect of law and business within the internet age and maybe a rewarding and lucrative career path.

Here are a couple of computer forensics programs and devices that make computer investigations possible:

Disk imaging software records the structure and contents of a tough. With such software, it’s possible to not only copy the knowledge during a drive but also preserve the way files are organized and their relationship to at least one another.

Software or hardware write tools to copy and reconstruct hard drives bit by bit. Both the software and hardware tools avoid changing any information. Some tools require investigators to get rid of hard drives from the suspect’s computer first before making a replica.

Hashing tools compare original hard disks to copies. The tools analyze data and assign it a singular number. If the hash numbers on an ingenious and a replica match, the copy may be a perfect replica of the first.

Investigators use file recovery programs to look for and restore deleted data. These programs locate data that the pc has marked for deletion but has not yet overwritten. Sometimes this leads to an incomplete file, which may be harder to research.

There are several programs designed to preserve knowledge during a computer’s random access memory(RAM). Unlike information on a tough drive, the info in RAM ceases to exist once someone shuts off the PC. Without the proper software, this information might be lost easily.

Analysis software sifts through all the knowledge on a tough drive, trying to find specific content. Because modern computers can hold gigabytes of data, it’s extremely difficult and time-consuming to look at computer files manually. For instance, some analysis programs search and evaluate Internet cookies, which may help tell investigators about the suspect’s Internet activities. Other programs let investigators look for specific content that will get on the suspect’s computing system. Encryption decoding software and password cracking software are useful for accessing protected data.

These tools are only useful as long as investigators follow the proper procedures. Otherwise, an honest defense attorney could suggest that any evidence gathered within the computer investigation isn’t reliable. Of course, a couple of anti-forensics experts argue that no computer evidence is totally reliable.

Whether courts still accept computer evidence as reliable remains to be seen. Anti-forensics experts argue that it’s only a matter of your time before someone proves during a court of law that manipulating computer data without being detected is both possible and plausible. If that is the case, courts may have a tough time justifying the inclusion of computer evidence during a trial or investigation.
