Signal head defends messaging app's security after US war plan leak

I guess Signal is a few steps above leaving a copy of your war plan at the Chinese Embassy — but it’s far below the standards required for discussing any elements of a war plan,

said Mark Montgomery, senior director of the Center on Cyber and Technology Innovation at the Foundation for Defense of Democracies

Companies like 23andMe that possess intimate information on the public must be held to the highest standards of privacy and transparency,

Torres said in a statement to POLITICO

Governor Youngkin’s veto means that Virginia’s AI sector can continue to flourish instead of getting bogged down in red tape,

Brianna January, Northeast government relations director at tech lobbying group Chamber of Progress, said in a statement

It is permissible to use to communicate and coordinate for work purposes, ... provided that any decisions that are made are also recorded through formal channels.”

he told the committee

Signal is as good as you can get — but it’s a (very) clear lesson that even the best technical cybersecurity can be overcome by human error.”

Still, a second former official said

If this was the case of a military officer or an intelligence officer, and they had this kind of behavior, they would be fired,

he added

In the absence of a solution and given the fast pace of national security affairs, people will resort to balancing their perception of the risk with the operational pressures of the day,

the official said

This means that Signal data is being delivered to potentially multiple desktop and laptop computers where it isn’t being stored in a phone’s secure enclave. That data is then at risk from commodity malware on the system. You can’t tell which of your contacts have their accounts linked to desktop machines, so you can’t evaluate the risk,

he said

This is one of the most stunning breaches of military intelligence I have read about in a very, very long time,

Senate Minority Leader Chuck Schumer, D-N.Y., said in a floor speech on Monday

CISA is releasing this best practice guidance to promote protections for mobile communications from exploitation by PRC-affiliated and other malicious cyber threat actors,

the CISA guidance states, referring to the Chinese cyber breach in 2024.

It was one of Michael’s people on the phone. A staffer had his number on there,

Trump told NBC News in a phone interview when asked how Goldberg was added to the high-profile chat

Michael Waltz has learned a lesson, and he’s a good man,

Trump said in the NBC interview

Adopt a free messaging application for secure communications that guarantees end-to-end encryption, such as Signal or similar apps,

the guidance states

It is, that is a practice that preceded the current administration to the Biden administration,

he continued

CISA strongly urges highly targeted individuals to immediately review and apply the best practices below to protect mobile communications. Highly targeted individuals should assume that all communications between mobile devices – including government and personal devices – and internet services are at risk of interception or manipulation. While no single solution eliminates all risks, implementing these best practices significantly enhances protection of sensitive communications against government-affiliated and other malicious cyber actors,

the guide reads

He’s not getting fired,

Trump told Fox News of Waltz

One of the first things that happened when I was confirmed as CIA director was Signal was loaded onto my computer at, the CIA, as it is for most CIA officers, one of the things that I was briefed on very early, Senator, was by the CIA records management folks about the use of Signal as a permissible work use,

he said

Michael Waltznational security adviser

There was no classified information, as I understand it, they used an app, if you want to call it an app. That's an app that a lot of people use."

Trump, with National Security Adviser Mike Waltz also in the room, continued to reporters in the White House after signing executive orders

Now if it's classified information, it's probably a little bit different,

Trump continued

If you show up with a warrant or a subpoena (to Signal), they have almost nothing about you that they can hand over,

Eva Galperin, director of cybersecurity at the Electronic Frontier Foundation, told CNN last month
