Security research


In August 2007, seventeen-year-old George Hotz became the first person reported to remove the SIM lock on an iPhone He traded his second unlocked 8 GB iPhone to Terry Daidone, the founder of CertiCell, for a Nissan 350Z and three 8 GB iPhones

In October 2009, Hotz released blackra1n It was compatible with all iPhone and iPod Touch devices running iOS 312

On July 13, 2010, Hotz announced the discontinuation of his jailbreaking activities, citing demotivation over the technology and the unwanted personal attention Nevertheless, he continued to release new software-based jailbreak techniques until October 2010

PlayStation 3

In December 2009, Hotz announced his initial intentions to breach security on the PlayStation 3 On January 22, 2010, he announced that he had performed his first achievement consisting of read and write access to the machine’s system memory as well as hypervisor level access to the machine’s CPU

On January 26, 2010, Hotz released the exploit to the public On March 28, 2010, Sony responded by announcing their intention to release a PlayStation 3 firmware update that would remove the OtherOS feature from all models, a feature that was already absent on the newer Slim revisions of the machine

On July 13, 2010, Hotz posted a message on his Twitter account stating that he had abandoned his efforts

Sony lawsuit

On December 29, 2010, hacking group fail0verflow did a presentation at the 27th Chaos Communications Congress where they exposed a mistake of Sony in their usage of ECDSA signatures without publishing the corresponding private key This key was used by Sony to prevent piracy On January 2, 2011, Hotz posted a copy of the private key of the PlayStation 3 on his website These keys were later removed from his website as a result of legal action by Sony against fail0verflow and Hotz In response to his continued publication of PS3 exploit information, Sony filed on January 11, 2011, for an application for a temporary restraining order (TRO) against him in the US District Court of Northern California

Hotz published his commentary on the case, including a song about the “disaster” of Sony Sony in turn has demanded that social media sites, including YouTube, hand over IP addresses of people who visited Geohot’s social pages and videos, the latter being the case only for those who “watched the video and ‘documents reproducing all records or usernames and IP addresses that have posted or published comments in response to the video”

PayPal granted Sony access to Geohot’s PayPal account, and the judge of the case granted Sony permission to view the IP addresses of everyone who visited geohotcom In April 2011, it was revealed that Sony and Hotz had settled the lawsuit out of court, on the condition that Hotz would never again resume any hacking work on Sony products


In June 2014, Hotz published a root exploit software hack for Samsung Galaxy S5 devices used in the US market The exploit is built around the CVE-2014-3153 vulnerability, which was discovered by hacker Pinkie Pie, and it involves an issue in the Futex subsystem that in turn allows for privilege escalation The exploit, known as towelroot, was designated as a “one-click Android rooting tool”

Although originally released for the Verizon Galaxy S5, the root exploit was made compatible with most Android devices available at that time For example, it was tested and found to work with the AT&T Galaxy S5, Nexus 5, and Galaxy S4 Active Updates continued to be applied to the root exploit to increase its capabilities with other devices running Android Updates to the Android operating system closed the source of the exploit Samsung officially responded to the towelroot exploit by releasing updated software designed to be immune from the exploit

Hotz founded his AI startup, commaai, in September 2015 In an interview with Bloomberg, Hotz revealed that the company was building vehicular automation technology based on machine learning algorithms Hotz built a working self-driving 2016 Acura ILX, which he demonstrated on California’s Interstate 280 freeway in a video, resulting in a cease and desist letter from the California Department of Motor Vehicles

Hotz wanted to sell his technology to Tesla Motors, meeting with CEO Elon Musk Hotz claims that Musk offered him $12 million (minus $1 million for every month it took Hotz to work on the task) to create a driving system that could replace the MobilEye solution that Tesla used at the time Tesla later released a statement on their website citing corrections to the Bloomberg article, stressing that their autopilot system was developed in-house, with a vision chip component from MobilEye, instead of one separate autopilot system manufactured by MobilEye, as suggested by Bloomberg reporter Ashlee Vance Musk offered advice on Hotz’s self-driving car project in a December 2015 interview

On October 27, 2016, the NHTSA informed Hotz that the product was legally required to comply with Federal Motor Vehicle Safety Standards, and requested information that would confirm such compliance A day later, George Hotz tweeted from Shenzhen that the comma one was cancelled Kristen Lee stated on Jalopnik that the NHTSA was simply trying to open a dialog, and commented: “Instead, they got the worst attitude possible from Silicon Valley: try and regulate us, thought leaders, and we’ll take our ball and go home”

commaai open sourced their self driving car software (called openpilot) on November 30, 2016, emphasizing its intended use for research without a warranty

On September 14, 2018, commaai announced Hotz would become the Head of Research Team for the project, and appointed Riccardo Biasini as the new CEO of the company He left in March 2019, but returned in May 2019 to become president once again
