An analysis of computer crimes

Conclusion Introduction There are no precise, reliable statistics on the amount of computer crime and the economic loss to victims, partly because many of these crimes are apparently not detected by victims, many of these crimes are never reported to authorities, and partly because the losses are often difficult to calculate. Nevertheless, there is a consensus among both law enforcement personnel and computer scientists who specialize in security that both the number of computer crime incidents and the sophistication of computer criminals is increasing rapidly.

Overview[ edit ] In the early s personal computers became more accessible to consumers, leading to their increased use in criminal activity for example, to help commit fraud.

At the same time, several new "computer crimes" were recognized such as cracking. The discipline of computer forensics An analysis of computer crimes during this time as a method to recover and investigate digital evidence for use in court.

The discipline also features in civil proceedings as a form of information gathering for example, Electronic discovery Forensic techniques and expert knowledge are used to explain the current state of a digital artifact, such as a computer system, storage medium e.

In a book, Computer Forensics, authors Kruse and Heiser define computer forensics as involving "the preservation, identification, extraction, documentation and interpretation of computer data".

However, while several methods can be used to extract evidence from a given computer the strategies used by law enforcement are fairly rigid and lack the flexibility found in the civilian world. This requires that information be authentic, reliably obtained, and admissible.

In the United Kingdomexaminers often follow Association of Chief Police Officers guidelines that help ensure the authenticity and integrity of evidence.

While voluntary, the guidelines are widely accepted in British courts. Computer forensics has been used as evidence in criminal law since the mids, some notable examples include: Dennis Rader was convicted of a string of serial killings that occurred over a period of sixteen years.

Towards the end of this period, Rader sent letters to the police on a floppy disk. Metadata within the documents implicated an author named "Dennis" at "Christ Lutheran Church"; this evidence helped lead to Rader's arrest.

A spreadsheet recovered from Duncan's computer contained evidence that showed him planning his crimes. Prosecutors used this to show premeditation and secure the death penalty. Hundreds of emails on Lopatka's computer lead investigators to her killer, Robert Glass.

This case confirmed parties' duties to preserve digital evidence when litigation has commenced or is reasonably anticipated. Hard drives were analyzed by a computer forensics expert who could not find relevant emails the Defendants should have had.

Though the expert found no evidence of deletion on the hard drives, evidence came out that the defendants were found to have intentionally destroyed emails, and misled and failed to disclose material facts to the plaintiffs and the court.

Conrad Murray, the doctor of the deceased Michael Jacksonwas convicted partially by digital evidence on his computer. This evidence included medical documentation showing lethal amounts of propofol.

Investigations are performed on static data i.

This is a change from early forensic practices where a lack of specialist tools led to investigators commonly working on live data. Techniques[ edit ] A number of techniques are used during computer forensics investigations and much has been written on the many techniques used by law enforcement in particular.

Cross-drive analysis A forensic technique that correlates information found on multiple hard drives. The process, still being researched, can be used to identify social networks and to perform anomaly detection.

The practice is useful when dealing with Encrypting File Systemsfor example, where the encryption keys may be collected and, in some instances, the logical hard drive volume may be imaged known as a live acquisition before the computer is shut down.

Deleted files A common technique used in computer forensics is the recovery of deleted files. Modern forensic software have their own tools for recovering or carving out deleted data.

File carving involves searching for known file headers within the disk image and reconstructing deleted materials.A Social Learning Theory Analysis of Computer Crime among College Students WILLIAM F.

Interactive Analysis of Computer Crimes P olice departments and other law enforce-ment agencies continually analyze vast amounts of criminal incident data to better understand crime in their jurisdictions, to identify significant changes in crime levels.

Real-life computer crimes investigation: It's not like on TV. Examination and analysis of forensic evidence can take weeks or months, and criminal cases may not go to trial for months or years.
