In further evidence to prove that any device or company can be hacked, a firm that develops and sells car breathalyzers was hacked, with its internal documents dumped on the dark web.

The hacking to light earlier this week, when a hacker named ROR[RG], a moderator of a hacking forum allegedly dumped internal documents of LMG Holdings. More to the point, the hacker dumped the documents of one of the companies owned by LMG called “LifeSafer.”

As reported by Motherboard, “LifeSafer” cites itself as a leader in ignition interlock technology. Fundamentally, ignition interlock technology is what is being used by breathalyzers for individual cars. The device locks the vehicle’s engine in such a way that the driver is required to blow into the device first. If the driver is over the legal alcohol limit, the car’s engine does not start.

LifeSafer notes that it has installed over 70.000 devices on vehicles spanning 46 states. The company also claims that all data received from every breath sample is sent to the authority or department who initially ordered the device to be installed.

Meanwhile, the hacker provided a link that contains a list of all the files on the hacker forum to claim a very plausible extortion attempt. The dumped directory revealed multiple dumps. One was uploaded on January 7th while two more larger dumps were shown to be uploaded on January 9th.

While the data itself isn’t significantly large, the contents showed company spreadsheets and specific instruction manuals for modifying and assembling products. Significantly, the dump also contained the source code for the ignition interlock technology along with detailed schematics of the company’s various products.

One of the products shown, from 2011, described the FC100. Another supplementary document detailed the means to adding “hardware improvements to the FC100. The company website states that the FC100 “is the most widely used interlock device in the United States.”

Another device, the “LifeSafer Interlock” had a specific schematic for the “Miniature Camera Board”, a document that was deemed and marked as “CONFIDENTIAL.” These are just a few of the files revealed, with dozens of other schematics and diagrams of circuit boards also included in the dump. Most of these files explain the fundamental working structure of LifeSafer’s products and has all the hallmarks of a serious breach affecting the company.
