ShinyHunters tells Cybernews operations are going strong as the FBI hackers post two new victims – O’Reilly Automotive and medical device giant Dexcom – on their brand-new leak site address Thursday.
The hacker gang – which spent the last week in a dramatic showdown with the FBI after allegedly hacking the federal agency on September 22nd – listed the two American companies side by side on its upgraded dark web victim blog.
ShinyHunters says it will publish data from both corporations “by end of day Friday if you do not reach out to us.”
No proof samples were listed with either breach entry.
ShinyHunters names O’Reilly Auto Parts, Dexcom as latest victims
O’Reilly Auto Parts, a leader in the automotive aftermarket industry, operates more than 6,500 retail stores nationwide and employs more than 94,000 team members, according to its website.
Based in Springfield, Missouri, and formed as a family business in 1957, the publicly traded company is now owned by a conglomerate of investment firms, including Vanguard, with a reported annual revenue of $17.78 billion in 2025.
Meanwhile, Dexcom, the California-based developer and global manufacturer and distributor of next-gen continuous glucose monitoring devices and other Type 2 diabetes management technology, was also claimed on Thursday.
Dexcom products – along with their companion apps – are used by more than 5 million people worldwide. The company reported 2025 revenue of $4.6 billion.
Although ShinyHunters did not provide any file samples of the alleged stolen data, Dexcom glucose sensors are designed to work in conjunction with its smartphone app for continuous monitoring.
This means a breach of Dexcom systems could potentially expose the sensitive health data of millions of individuals worldwide who use the blood sugar sensing technology.
Cybernews has reached out to both O'Reilly Automotive and Dexcom for comment, but has not heard back at the time of publish.
