UFED is a special device used by the FBI as a tool cracking smartphones. It is also used by the US Department of Homeland Security and many law enforcement agencies in other countries. Recently, however, the gadget has become available to literally everyone. Modern devices of this type are actively sold at a price of 500 – 15,000 dollars (prices depend on the model). However, their relatively old models are found on eBay and for $ 100. They say that the police are selling them. Moreover, in some cases, they have information extracted from smartphones, among them even the one used in criminal investigations. As a result, leaks appeared. One security expert conducted a special investigation. He revealed on some of the kits he acquired data on which devices were cracked with their help, as well as what information and when it was possible to obtain. Among other things, there were mobile identifiers like IMEI code, text messages and contact lists. These gadgets are not compatible with the latest versions of iOS. However, the study showed that with this device it was possible to access the locked iPhone X, controlled by iOS 11. Google and Apple are constantly struggling with devices of this kind that work with unknown manufacturers and zero-day vulnerabilities. Cellebrite produces such gadgets. It prohibits reselling unnecessary devices, requiring that they be returned to the company.
