How USB Forensics Can Uncover Illegal Activity

For the past decade, digital forensics has been a hugely prominent force in the fight against illegal activity. Cases can be supported or dismissed on account of evidence gleaned from mobile forensics, computer forensics, and cell site analysis. However, cases usually require a device such as a smartphone or a laptop to be in the possession of the prosecution – but what if the information has been placed onto a computer or copied from a computer, and you don’t have access to the physical hardware used to do so?

 

The good news is that ICFECI – the best private investigator Dallas has to offer – can uncover the history of every device connected to your computer via USB.

 

Private investigator Texas: why USB connectivity information matters

 

In an age of wireless connectivity, you might not think USB device connection history is important. However, proof that a USB device has been connected to your computer in your absence could help support your case. The idea of a connected USB device may seem innocuous enough, but it’s a fact that USB connection history is useful can be useful to determine:

 

  • When sensitive information (such as bank details) has been copied from a computer.
  • When illegal files have been copied to or from a computer.
  • When a mobile device has been charged via a computer (for example, if a cheating spouse allowed their lover to charge a phone via a USB slot on a laptop).
The above scenarios are just three examples of how people can leave a digital footprint via USB connectivity. As the best private investigator, Fort Worth has to offer, we’re able to employ a series of complex digital forensics techniques to identify when devices have been connected to your device and the purpose of the connection of these devices.

 

How can I tell what USB devices have been connected to my computer?

 

Computers feature a database known as the registry. This registry is where the core settings of the operating system are stored. Whenever a USB device is inserted into a computer, a key is created within the registry. This registry key contains information about the USB device, and with the right tools and know-how, a private investigator can extract this information.

 

If you’d like to know more about how our digital forensics services could help you identify when USB devices have been connected to your computer, why not get in touch with the team at ICFECI today. We’ll be happy to discuss your requirements and offer advice on how our service could benefit you.

Challenges in Mobile Forensics: How Manufacturer Security Is Getting Tighter

In 2020, the main challenge for cell phone forensics teams has continued to be encryption. This year, the encryption bundled with Android devices as standard has started to cause issues for computer forensics firms.

While encryption has been around since Android 6, all mid-range Android devices and Samsung smartphones prior to 2019 made use of Full Disk Encryption or FDE. This form of encryption uses a less secure encryption scheme that protects mobile data with “default password” as the encryption seed key – nothing new for your average purveyor of computer forensics in Dallas to crack.

As of 2020, most new cell phones come with File-Based Encryption (or FBE of short). This newer encryption scheme encrypts files with a key based on the screen lock passcode of the user. While experts in computer forensics in Texas can still prevail when it comes to decrypting data from new smartphones, acquisitions will undoubtedly become significantly more time-consuming and difficult as a result.

Why Android forensics is causing headaches

For those without mobile forensics expertise who need to access encrypted data, Android is causing some serious problems. The smartphone market is saturated with thousands of different low-budget Android models. These models are equipped with all sorts of different chipsets from a variety of manufacturers.

Powerful data acquisition methods, such as EDL extraction, can be used to access a special “safe mode” which exists on most devices for engineering/diagnostic purposes. However, these methods might not be suitable and will depend on individual device settings which could actually enforce enhanced encryption, should the device recognize that its data may be compromised.

Dedicated forensic tools

Ultimately, in 2020 a computer forensics team in Texas will need an arsenal of dedicated forensic tools to access encrypted data. In addition to this, they may employ techniques such as cloud extraction to acquire data.

If you’re in Dallas and have been locked out of a cell phone, or need to access encrypted data for legal purposes, chances are you’ll need access to computer forensics in Texas to achieve the desired result. In 2020, technology has become incredibly complex, and it pays to let the experts do the work for you.
