Signal app threatens to leave Europe over chat control law

Meredith Whittaker, head of the Signal messaging app, stated that Signal is prepared to exit the EU market if legislation allows authorities to bypass encryption to scrutinize private messages. Whittaker emphasized that Signal would prioritize user privacy over compliance with such regulations. The EU is discussing a law aimed at combating the dissemination of child sexual abuse material, which would require messaging platforms to scan messages before encryption. WhatsApp's head criticized the proposed law, claiming it jeopardizes user privacy, while Threema expressed concerns about mass surveillance being incompatible with democratic principles. The European Parliament largely opposes the initiative, while the Council of Member States shows majority support for control measures. Additionally, an incident was reported where an unknown individual used AI-generated voice technology and Signal to impersonate Secretary of State Marco Rubio and contacted five government officials.

Messaging app Signal will block Windows Recall from taking chat screenshots

Signal has introduced a "Screen Security" feature in its desktop application to prevent external programs, including Windows 11, from capturing screenshots of its interface. This feature is enabled by default and is a response to Microsoft's Recall feature, which captures app window screenshots for AI processing. Signal is concerned about the privacy risks posed by Recall's design, despite Microsoft's assurances of improved privacy controls. The developers have used Windows' Digital Rights Management technology to protect against unauthorized screenshots due to the lack of official APIs from Windows 11. Signal's leadership has criticized the need for such workarounds and has called on Microsoft to provide better tools for developers to safeguard user privacy.

Wrong signal: Donald Trump shoots the messaging app instead of the messmaker

Maher became the non-executive chair at Web Summit after leaving her CEO position last year to lead NPR. She also chairs the Signal Foundation, known for its encrypted messaging service, which was used by Trump administration members during military planning in Yemen, leading to criticism from Trump supporters due to her previous comments about Trump and her advocacy for restricting free speech. Meanwhile, Gordon Hardie, CEO of O-I Glass, received a total compensation package of €1.46 million last year, which included a base salary of €682,322, stock awards, and additional benefits. The University of Limerick recently ceased posting on X due to declining engagement and concerns over content, though it remains open to reconsidering its stance. Peter Vandermeersch, CEO of Mediahuis Ireland, is writing a book titled “Ierland. Guinness, God en Google,” which will explore various aspects of Irish life and culture.

Florida’s Mike Waltz and Marco Rubio on text chain that included journalist. What we know

A Florida politician, National Security Adviser Mike Waltz, was involved in a national security breach after inadvertently including a journalist in a group chat on the Signal messaging app. The chat contained sensitive discussions about U.S. airstrikes against Iranian-backed militants in Yemen, specifically targeting Houthi sites, with critical details shared by Defense Secretary Pete Hegseth just hours before the strikes on March 15. President Trump claimed no classified information was shared despite the seriousness of the situation. The National Security Council is investigating the breach, and Waltz has taken responsibility for the error. The incident raises questions about the use of Signal, an app designed for secure communications, for sensitive government discussions and potential violations of the Presidential Records Act.

Days after the Signal leak, the Pentagon warned the app was the target of hackers

A Pentagon advisory warns against using the messaging application Signal for any communications, even unclassified ones, due to a vulnerability exploited by Russian hacking groups. This follows an incident where a journalist was inadvertently included in a Signal chat about military operations in Yemen. The advisory, dated March 18, indicates that Signal is not authorized for processing or storing non-public unclassified information, despite previous guidance allowing its use for unclassified accountability exercises. A 2023 Department of Defense memo also prohibited using mobile applications for controlled unclassified information. The accidental inclusion of a journalist in sensitive discussions is termed “spillage,” which can endanger military careers. Signal's spokesman stated that the memo does not reflect concerns about the app's inherent security but emphasizes vigilance against phishing attacks.

What Is Signal, the App Involved in a War Plans Security Breach?

Signal has recently garnered attention due to reports that senior officials from the Trump administration used the platform for sensitive war planning discussions, inadvertently including a journalist in the messaging group. This incident has raised questions about the appropriateness of using Signal for classified discussions, particularly since federal employees are usually prohibited from installing such applications on government-issued devices. Signal, launched in 2014, is an encrypted messaging application that facilitates secure communication through end-to-end encryption, ensuring messages remain private and unreadable until they reach the intended recipient. It also offers a feature for messages to disappear after a set period. Signal is operated by the Signal Foundation, an independent nonprofit organization funded by donations and grants, which allows it to prioritize privacy and security without commercial influences.

What is Signal?

A magazine journalist was unexpectedly included in a group chat of U.S. national security officials on the Signal messaging app, just hours before President Donald Trump authorized airstrikes against Iran-backed Houthi rebels in Yemen. The National Security Council is investigating how the journalist's phone number was added to this secure communication channel. Signal is an application that supports direct messaging, group chats, and voice and video calls, employing end-to-end encryption. It allows for group chats of up to 1,000 participants and includes a feature for messages to self-destruct after a set period. Signal is considered secure but not immune to hacking, and it raises concerns about compliance with open records laws. Government officials are increasingly using encrypted messaging applications, with many having accounts linked to government-issued and personal cell phones. Signal was created by Moxie Marlinspike, who combined two open-source applications, and is overseen by the nonprofit Signal Foundation, which operates without advertisers or investors.

What is Signal? 5 things to know about the app used in Trump administration war plans leak

Sensitive military strategies regarding Iranian-backed militants in Yemen were inadvertently disclosed to journalist Jeffrey Goldberg when he was included in a group chat on Signal with Trump administration officials, including Mike Waltz, Pete Hegseth, JD Vance, Marco Rubio, and Tulsi Gabbard. The White House National Security Council confirmed the authenticity of the chat. Hegseth stated that “Nobody was texting war plans.” President Trump expressed discontent with The Atlantic regarding the incident. The situation has prompted calls for accountability from Democratic lawmakers. Moxie Marlinspike, co-founder of Signal's parent company, highlighted the app's unexpected role in military coordination. Signal is a free, open-source messaging application with end-to-end encryption that accommodates up to 40 participants and supports various media formats. Originally developed by Whisper Systems, it emerged from two separate applications: RedPhone and TextSecure. Signal is popular among activists, politicians, and journalists for secure communication, but its use for government communications may violate the Presidential Records Act and the Federal Records Act, which require that official communications be preserved. Messages in the military strategy chat were set to disappear after a week, raising questions about record-keeping compliance.

What is Signal messaging app? Can Bucks County, PA agencies use it

Signal is an encrypted messaging application owned by the nonprofit Signal Foundation, known for its end-to-end encryption. The app has drawn attention in a controversy in Bucks County, Pennsylvania, involving allegations that school board members used Signal to communicate after being instructed to retain records related to a Sunshine Act lawsuit. This has raised concerns about the potential destruction of evidence, as Signal's auto-delete feature may violate federal record retention laws. Additionally, during the Trump administration, Mike Waltz inadvertently included a journalist in a Signal chat discussing a military strike, raising questions about the appropriateness of using commercial messaging for sensitive government communications. The use of auto-deleting messages has sparked debate regarding public accountability and compliance with the Presidential Records Act, as many records must be retained for a minimum of two years.
