Data Forensics and Recovery: What is It?
You always hear about “digital footprints” and “data breaches” these days, but most people are unaware of what these mean exactly.
Ever since the floodgates of the “information superhighway”, as the internet had been dubbed as back in the turn of the millennium, data and information have become the currency of choice of the tech savvy crowd. And this is not simply limited to so-called crypto-currency. Any data can have some sort of value when applied properly. This is particularly the case for sensitive data like personal information, usernames and passwords, bank account numbers, social security numbers, credit card numbers and PINs, and so on. This is why erasure and removal of such data from drives should be conducted thoroughly before letting go of devices which may have them. Sinister parties may recover them from old drives and then used to their ends and then mislead investigators into putting the blame on the innocent.
However, standard deletion and reformat (or resets for Apple/Mac devices) are NOT 100% guaranteed to clear the data. Without the use of a similar system as the RedKey USB data wipe tool, fragments or even full files are recoverable through the same process as Data Forensics experts use or through programs such as Recuva. Understanding how data forensics and recovery software works can help you avoid being the target of unscrupulous individuals.
What is Data Forensics and Recovery?
The concept and practice of data forensics is not new. Although it has become a buzz word of sorts due to the data breaches from recent years, notably the Sony breach of 2014, data forensics and recovery has been around since the 1970s. By the late 1970s, establishment in the United States of the Computer Analysis and Response Team arm of the FBI and the UK’s British Fraud Squad were clear indications that governments were taking data security very seriously. As time progressed and computers became more advanced, this prioritisation of data protection and security, as well as the ability to recover and track information, became more and more apparent. Criminal and terrorist investigations required more reliable ways to examine, gather, and recover traces of data.
The basis of data forensics and recovery is fairly straightforward. The target source, for instance a hard drive, is copied (as the original would not be altered in any way) for examination. Once this is done, the immediate information (i.e. non-hidden) is collated and reviewed. It is when the search for hidden data commences that data forensics is truly highlighted. Hidden data can be recovered from deleted files or reformatted drives using the right tools.
What is Recuva?
File recovery tools are the primary programs in data forensics. Generally, files can be restored after deletion until the space from the drive is overwritten. One of the more popular file recovery tools today is Recuva. Recuva generally works for Windows PCs as it is not compatible with the Mac OS. Also called an undeletion program, Recuva was developed under Piriform Ltd., a British software company. Its popularity stems from its ease of use and being able to work on FAT and NTFS file systems.
How to Protect Myself from Unwanted Data Recovery?
In order to prevent one’s data from being used improperly, it is highly recommended that you use a reliable data wipe tool like RedKey USB. If your old hard drives fall into criminal hands after a RedKey USB data wipe, not even programs like Recuva can undelete your sensitive files. This is because the powerful RedKey USB system not only destroys every trace of the data, but also overwrites their presence in the drive as part of the process.
