In many forensic investigations, data is destroyed or damaged because of an individual trying to hide or destroy the data through various means (such as throwing the hard drive into the lake or smashing the hard drive with a hammer). …
What is meant by the term anti-forensics mean?
“Attempts to negatively affect the existence, amount and/or quality of evidence from a crime scene, or make the analysis and examination of evidence difficult or impossible to conduct.” One of the earliest detailed presentations of anti-forensics, in Phrack Magazine in 2002, defines anti-forensics as “the removal, or …
What are the three main steps in forensic process?
The process is predominantly used in computer and mobile forensic investigations and consists of three steps: acquisition, analysis and reporting.
What is anti-forensics in cyber security?
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.
What are anti-forensics techniques?
- DESTRUCTION OF EVIDENCE. This method aims to eliminate evidence and make its recovery impossible. …
- EVIDENCE HIDING. This method does not aim to manipulate or destroy evidence but make it as inaccessible as possible. …
- ELIMINATION OF THE SOURCES OF EVIDENCE. …
- EVIDENCE TAMPERING.
What is meant by steganography?
Steganography is the practice of hiding a secret message inside of (or even on top of) something that is not secret. That something can be just about anything you want. These days, many examples of steganography involve embedding a secret piece of text inside of a picture.
What tools do anti-forensics use?
Fascinating Anti-Forensic Techniques to Cover Digital Footprints

- Steganography. Steganography is the act of concealing data in plain sight. …
- Tunneling. …
- Onion Routing. …
- Obfuscation. …
What are the 4 steps of the forensic process?
The first digital forensic process model proposed contains four steps: Acquisition, Identification, Evaluation and Admission. Since then, numerous process models have been proposed to explain the steps of identifying, acquiring, analysing, storage, and reporting on the evidence obtained from various digital devices.
How long does a forensic investigation take?
A complete examination of a 100 GB of data on a hard drive can have over 10,000,000 pages of electronic information and may take between 15 to 35 hours or more to examine, depending on the size and types of media.
What are the six phases of the forensic investigation process?
This model was the base fundament of further enhancement since it was very consistent and standardized, the phases namely: Identification, Preservation, Collection, Examination, Analysis and Presentation (then a pseudo additional step: Decision). Each phase consists of some candidate techniques or methods.
What is artefact wiping?
Artifacts wiping is similar as destroying evidence. If someone unknowingly or intention- ally leaves some artifacts in the system, then wiping this information is called artifact. wiping.
What anti-forensics techniques do criminals use to circumvent mobile forensics analysis?
Criminals will use otherwise legitimate apps to hide their criminal activity. Anti-forensics techniques attempt to circumvent mobile forensic examiners by hiding data, data obfuscation, data forgery, and secure wiping.
What is the difference between artifacts and evidence?
Artifact: A piece of data that may or may not be relevant to the investigation / response. … Evidence: A piece of data (artifact) that is relevant to your investigation because it supports or refutes a hypothesis.
What techniques might criminals use to hide data or activities?
Today, criminals engaged in digital crime can either hide information or hide data in plain sight as it travels along the World Wide Web. The two most common types of information-hiding practices are steganography and cryptography.
What is the role of encryption in Antiforensics?
Cryptographic file systems transparently encrypt data when it is written to the disk and decrypt data when it is read back, making the data opaque to any attacker (or CFT) that does not have the key. These file systems are now readily available for Windows, Mac OS, and Linux.
What is the use of write blockers in digital forensics investigation?
A write blocker is any tool that permits read-only access to data storage devices without compromising the integrity of the data. A write blocker, when used properly, can guarantee the protection of the data chain of custody.
