6 Anti-Forensic Techniques to Cover Digital Footprints

After the positive attempt of digital forensics to minimize cyberattacks, anti-forensic techniques came into existence to make it challenging for cyber forensic experts to identify culprits. It has been hindering the work of computer investigators, ever since its inception. The basic idea behind anti-forensic techniques is to erase footprints or make them impossible to track. As forensic investigators start at the end, it becomes difficult to establish any facts in the absence of prior knowledge.

Although the concept of anti-forensics is nothing new, the past few years saw a spike in its use. Several reasons that sum up this rise are –

  • The launch of more sophisticated anti-forensic tools, and
  • Its availability to threat actors working on Unix as well as Windows.

In simpler words, anti-forensic tools are now available to even non-technical users.

Defining Anti-forensics

With the increasing security incidents, even the use of anti-forensic tools is rising. To retrieve digital evidence, which is admissible in court, cyber forensic investigators need to follow a strict procedure. During a forensic investigation, several factors can disrupt the recovery of digital evidence. It could be a human element or dependency on tools. Even the physical and logical limitations can impact the examination. As a result of this, digital investigators face challenges when keeping up with advanced technologies.

Without a standard definition for anti-forensics, the concept is open to perception, and that’s how investigators retrieve digital evidence based on their personal experiences. In such a situation, it’s best that the cyber forensic investigators exchange their experience, so that they can learn from each other. By sharing knowledge, one could formulate effective mitigation strategies.

Detect anti-forensics techniques

Organizations have now started putting up fake assets to lure cyber attackers. These assets offer a limited amount of data to keep cybercriminals engaged until the security professionals track them. Any malicious activities on these assets alarm the security professionals and initiate the required incident response. Skilled digital forensic experts can seek clues by investigating these assets through anti-forensic measures. They rely on the presence of cryptographic tools, rootkits, an encrypted Virtual Machine (VM), and other pieces of evidence. Also, the investigators use their own trusted programs to retrieve information. Familiarity with private programs makes it easy for examiners to detect anti-forensic techniques.

Approaching the problem of anti-forensic techniques

The right solution is to build a healthy community of digital forensic investigators. The experience of skilled professionals will help others to stay one step ahead of obfuscation, steganography, encryption, tunneling, and other anti-forensic measures. The community should share their discoveries so that others won’t fall for the same mistake. Other than that, maintaining a continuous educational environment will be a wise move.

How to become a digital forensic investigator?

Now, if you are someone who wants to contribute to this domain, you can register for Computer Hacking Forensic Investigator (C|HFI). The program leads you through the process of detecting hacking attacks and retrieving pieces of digital evidence. These clues then used to either track down the attacker or prevention of future attacks.

What is anti-forensics in cybersecurity?
Anti-forensics is an approach used by cybercriminals to challenge evidence gathering and analysis processes. The primary purpose of anti-forensic techniques is to make it hard or even impossible for a cyber forensic investigator to conduct a digital investigation.
