Work details of more than 40,000 DHS staff were taken and posted online, reports say
Reported by TechCrunch and CyberScoop, both published Wednesday, October 28, 2026.
What happened
TechCrunch reports that a hacker took work details about people at the Department of Homeland Security (DHS), and the data has been posted online. It says the records cover more than 40,000 people. CyberScoop puts the number at more than 41,000 employees and contractors. TechCrunch says the records hold names, job titles and work contact details, such as email addresses.
What the reports say about how it happened
The hacker claims the data came from an Okta single sign-on system used at DHS. Single sign-on lets a person use one login to reach many work systems. Both outlets quote an Okta spokesperson as saying the company has "no evidence our data or systems were compromised." TechCrunch reports that a DHS spokesperson said DHS is aware of a potential breach and is working to address it. CyberScoop wrote that DHS did not immediately respond to its request for comment.
Hackers stole about $6.3 billion in cryptocurrency from Binance, reports say
Reported by Reuters and Cybersecurity Dive, both published Friday, October 30, 2026.
What happened
Reuters reports that hackers stole $6.3 billion from Binance, a cryptocurrency exchange. An exchange is a company where people buy, sell and hold cryptocurrency, a kind of digital money. Reuters quotes Elliptic, a British firm that tracks cryptocurrency, as saying: "This incident is almost certainly the single largest known theft of any kind." Cybersecurity Dive reports that Binance called it the largest cryptocurrency theft in history.
Reuters reports that two other firms that track cryptocurrency are highly confident North Korea was responsible. Reuters notes that North Korea routinely denies such claims.
Binance said customer funds were safe, Reuters reports. Cybersecurity Dive says Binance promised to cover all losses, and has stopped deposits and withdrawals while it looks into the theft. A Secret Service spokesperson said investigators are working with partners to "identify, freeze, trace, and recover" the stolen funds, Cybersecurity Dive reports.
What the reports say about how it happened
Cybersecurity Dive reports that Binance said the attackers broke into several systems, including an engineer's laptop. Reuters reports that Binance's co-chief executive said the hackers moved money out of an internet-connected Binance wallet without going through normal approval checks.
