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 is meant by anti-forensics?
“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 is the impact of anti-forensics?
If an employee uses anti-forensics techniques in an effort to cover up illegal activities before their data is collected in an investigation, the time and cost of the investigation can increase drastically.
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 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 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 type of crimes can be committed using steganography?
Steganography can also be used to hide coded messages in images. A cyber criminal may take a picture of a landscape, for instance, and hide a message or malicious file in the empty spaces of that file. Then, they can transmit the image to its intended recipient who knows to decode it.
How BitLocker can be used as anti forensics tools?
Previous versions of Windows have used the encrypting file system (EFS), allowing users to selectively encrypt files and folders on a drive. The technology is called BitLocker, and poses a problem for forensic investigators, as all information on the drive will be encrypted, and therefore unreadable.
How is steganography done?
Steganography works by replacing bits of useless or unused data in regular computer files (such as graphics, sound, text, HTML, or even floppy disks) with bits of different, invisible information. … The most common form used today hides files within image files on a computer.
Why is steganography needed?
The purpose of steganography is covert communication to hide a message from a third party. This differs from cryptography, the art of secret writing, which is intended to make a message unreadable by a third party but does not hide the existence of the secret communication.
Where is steganography used?
Uses of Steganography. Steganography means of storing data in a way that it hides the existence of them. Steganography used to carry out hidden exchanges . For example, Governments are interested in two types of communication of hidden data: first, which supports national security and second, which does not.
