Today’s Big Story

Binance’s Record Breach

• Hackers took about $6.3 billion from Binance Thursday in what blockchain investigators described as the largest cryptocurrency theft on record. The world’s largest cryptocurrency exchange paused withdrawals and promised to cover customers’ losses using company money and its emergency protection fund.

• Investigators initially suspected that a compromised engineer’s laptop allowed attackers to submit unauthorized withdrawals through an internal system. Binance has since uncovered additional breach points but has not established the full sequence. The company is reviewing its security before restoring withdrawals and hopes to resume them Sunday. Deposits remain operational.

• Binance said roughly $3 billion in affected assets had been frozen to prevent further transfers but had not necessarily been recovered. Blockchain analysis firms TRM Labs and Chainalysis attributed the attack to North Korea based on similarities to earlier thefts. Binance has not independently confirmed who was responsible.

Saturday’s Quick Hits

• Foreign ministers from the Group of 20 economies met in Atlanta Friday for talks on wars and threats to global trade. Secretary of State Marco Rubio is hosting the two-day gathering ahead of December’s leaders’ summit. Washington’s priorities include shipping-route security and access to critical minerals. Russia’s foreign minister attended, but South Africa was not invited. (More)

• Pope Leo XIV became the first pontiff to vote in a U.S. general election after submitting a mail-in ballot for Illinois ahead of Tuesday’s midterms. The Chicago-born pope retains U.S. citizenship despite leading the Vatican. His voting record includes requests for both Democratic and Republican primary ballots but does not reveal which candidates he supported. The Vatican described voting as both a right and a civic duty. (More)

• A trial involving 830 children under six found that a liquid painted onto cavities stopped decay in more than half of treated baby teeth. Silver diamine fluoride can be applied without drilling or injections and may help children who struggle with conventional dental work. U.S. dentists already use it off-label for cavities. The study supports seeking FDA approval for that purpose but does not establish an approval timetable. Its main drawback is permanent darkening of decayed tooth tissue. (More)

• Congo’s Ebola outbreak has passed 10,000 confirmed cases as health workers struggle to trace infections. Weekly cases have leveled off at roughly 400 to 500 rather than declining. Fewer than a quarter of new patients were already identified as contacts of infected people. Experts say that leaves transmission chains undetected. Cases have appeared abroad, but researchers said the direct risk to the U.S. is very low. (More)

• An Australian appeals court ordered Erin Patterson to spend the rest of her life in prison Friday for poisoning relatives with death cap mushrooms. The court rejected her challenge to three murder convictions and accepted prosecutors’ appeal against her sentence. The ruling removes the previous possibility of parole after 33 years. Three guests died after the 2023 lunch and a fourth survived. (More)

• President Trump restored campaign stops in Iowa and Kansas Friday after initially canceling them in favor of telephone events. Both in-person rallies are now planned for Sunday alongside the additional calls. The stops support Republicans in competitive Senate races as voters decide control of Congress Tuesday. (More)
