My initial reaction to Iran's response was surprise at how weak it seemed. Until the UAE released data on missiles-UAVs launched vs missiles-UAVs intercepted. In cyber, offense generally wins. In kinetics, at least in this one case, defense won.

"In the end, the talks between Anthropic and the Department of Defense were undone by weeks of building frustration between men who had differing philosophies about A.I. and who did not like one another."

Canceled contracts, a failed polygraph and personal disputes: Inside the turbulent tenure of Noem’s former cyber czar A dozen current and former officials said that former acting CISA director Madhu Gottumukkala's leadership was troublesome for the agency long before his reassignment late Thursday.

β€œI don’t think people realized how ill-served we, the American public, were by having someone that was this unserious, just asleep at the wheel in an agency leadership position like this,” said one of the four officials. www.politico.com/news/2026/02...

Hegseth: "Israel has clear missions as well for which we are grateful. Capable partners are good partners, unlike so many of our traditional allies who wring their hands and clutch their pearls, hemming and hawing about the use of force ... no stupid rules of engagement."

Across party lines and industry, the verdict is the same: CISA is in trouble One year into the second Trump administration, CISA faces a 33% loss in personnel and shuttered divisions. Experts warn of "decimated" capabilities and a leadership vacuum as the agency struggles to m...

Seeing the lengthy list of changes/cutbacks to CISA catalogued in this one piece makes it clear there is little left of it. The agency is less than a decade old and struggled for years to find its footing before it started to make progress. But all advances it made have been gutted in last 12 months

They've teased this for weeks as Pitt staff have placed bets about why another hospital in same city was having to send their patients to the Pitt. They finally revealed last wk it was due to ransomware - the reveal came just as the Pitt's own computers went down. Tonight's ep should be interesting

4Chan knew about Jeffrey Epstein's death 38 minutes before the rest of the world. The FBI tried to figure out how. The Epstein files address a long-running side plot of Jeffrey Epstein's 2019 death while in jail on sex-trafficking charges.

Great pull from the Epstein files. FBI tried to figure out who on 4chan had scooped all news outlets on Epstein's death, but the trail went cold when they couldn't find who had that IP address.

"It’s unclear how [Bucher] landed a gig doing publicity for...Jeffrey Epstein...but in 2017, when she still had her original last name, Drokova, she asked Epstein to connect her with 'adequate Russian oligarchs'" per the recently released Epstein files.

Trump admin's favorite nuclear startup -- Valar Atomics, a California firm that aims to make small-scale nuclear reactors -- has ties to Russia and to Epstein through Masha Bucher, a "one-time pro-Putin Russian political activist-turned Jeffery Epstein publicist-turned Silicon Valley kingmaker"

For those who don't understand the "banality of evil" reference, it's from Hannah Arendt's book about Adolf Eichmann's trial in Israel. She used it to describe how ordinary Germans/Poles/Ukrainians became accomplices to the Nazis by mindlessly buying into the demonization of their Jewish neighbors

Prince Andrew's Arrest Across the pond in Britain, justice and accountability is a serious matter

Never in a million years did I ever fathom when I resurrected the Epstein story in 2018 that it would lead to first arrest of a British Royal in four centuries. Not since King Charles I was arrested in 1647.

The Caracas operation suggests cyber was part of the plan – just not the whole operation Was the Caracas power outage a "precision cyberattack" or something more physical? Experts weigh in on the visible kinetic damage to Vene.zuelan substations during Operation Absolute Resolve.

Good piece from @metacurity.com about whether cyber played significant role in power outage during Caracas raid. "How the outage is framed matters because...if the episode is widely presented as a 'cyber-only' success...it may encourage outsized conclusions about what cyber tools can accomplish"

Password managers' promise that they can't see your vaults isn't always true Contrary to what password managers say, a server compromise can mean game over.

The makers of password managers like Bitwarden, 1Password, Dashlane and LastPass promise they can't see your password vault. But that's not always true. A server compromise can mean game over for you, say researchers who examined some of the top password managers on the market

Hackers made death threats against this security researcher. Big mistake. Allison Nixon had helped arrest dozens of members of The Com β€” a loose affiliation of online groups responsible for violence and hacking campaigns. Then she became a target.

When a hacker named "Waifu" and "Judische" began posting death threats against security researcher Allison Nixon, she had no idea why he targeted her. So she set out to unmask him. The quest led her to Connor Moucka, a 25-yr-old Canadian who was ringleader of infamous Snowflake/AT&T hacks. My story:
