Questions about this signal
What happened in this signal?
Microsoft accused of leaking Dutch civil servants' names to U.S. government Microsoft has reportedly shared the names of Dutch civil servants working for two regulatory agencies with the U.S. House of Representatives. The agencies involved include the Authority for Consumers and Markets (ACM) and the Dutch Data Protection Authority (AP), according to an article published on Friday by Vrij Nederland. The civil servants involved are working on implementing the Digital Services Act (DSA), the European law that forces online platforms to take stricter action against illegal content, online child sex abuse, and disinformation. The American government considers this law a form of censorship. Microsoft shared emails, minutes, and invitations sent by these civil servants without redacting their names in the documents. American tech companies are required to share data with the U.S. government due to the Cloud Act in force in that country. State Secretary Eric van der Burg of Interior is concerned that Microsoft simply shared civil servants’ names with the U.S. government. But he first wants to investigate how the names were shared and in what documents before drawing conclusions. State Secretary Willemijn Aerdts for Digital Economy and Sovereignty has spoken with the U.S. Ambassador Joe Popolo about the allegations. The D66 politician said this happened some time ago, and she raised the issue with Popolo during her introductory meeting with the ambassador. “I said how undesirable this is. If you have a problem, you fight it out with us or, if necessary, in Europe, but not against the backs of civil servants,” Aerdts told ANP before heading into the Council of Ministers meeting on Friday. There is a broad desire within the Netherlands to become less dependent on major American tech companies , specifically because of the Cloud Act. Both Aerdts and Van der Burg stressed that it will take time for the Netherlands to become digitally sovereign.

South Korean Diplomatic Academy Suffers Significant Data Leak Affecting 10,000 Diplomats
On July 21, 2026, the Korea National Diplomatic Academy, an institution affiliated with South Korea's Ministry of Foreign Affairs, confirmed a significant data leak impacting approximately 10,000 records of current and retired diplomats. The breach, which occurred in the academy's online education system, was discovered in early February 2026 after suspicious access was reported by a government agency. An unidentified attacker exploited a zero-day vulnerability in the server software and weaknesses in system security settings, maintaining unauthorized access from April to May 2025 until February 2026. The compromised data reportedly included names, user IDs, email addresses, encrypted passwords, job titles, and affiliated departments. While sensitive personal information such as resident registration numbers, mobile phone numbers, and home addresses were not present on the affected server, the leak of diplomat information raises concerns, especially given that the full list of diplomats and personnel at overseas missions is not publicly disclosed. The Foreign Ministry is investigating the incident and has urgently shut down the compromised system. They are operating under the assumption that a substantial volume of data was compromised, though the exact scale of the damage is still being assessed. The incident highlights the challenges in detecting sophisticated attacks that leverage previously unknown vulnerabilities.

Peter Thiel's Dialog Society Data Leak Exposes Senior US Officials
Pentagon Probes Data Leak at Peter Thiel's Dialog Exposing Senior US Officials The Pentagon is investigating a data exposure at Peter Thiel's secretive Dialog group after a misconfigured website unmasked senior U.S. intelligence officials and active-duty special operations personnel, raising operational security risks. The briefing room at the Pentagon in Virginia, January 8, 2020 - Reuters The Pentagon has launched an operations security examination into a major data exposure at Dialog, a secretive private events group co-founded by Peter Thiel. The breach compromised the personal information of multiple U.S. national security personnel. These include an active-duty intelligence officer embedded with a Tier 1 special operations unit and a senior National Security Council official advising President Donald Trump, according to WIRED. The exposure revealed private details of 222 registrants for the Dialog event. The database included current and former senior military and national security officials from the United States and allied nations. The active-duty military intelligence officer and the NSC official were registered as new participants. Both were invited to attend Dialog’s upcoming August retreat located outside Dublin, Ireland. The White House declined to comment on the exposure. Officials requested that the NSC official, a former CIA officer, remain unnamed on national security grounds. Dialog internally classified the incident as a cyberattack. However, evidence indicates the files were exposed due to a misconfiguration in the group’s website. Anyone could create an account with an email address to access the files. Users simply needed to load the group’s application landing page to view the dossiers. Outside counsel for Dialog issued a letter stating that the data was stolen and demanding its return. The organization did not respond to press inquiries regarding the incident. The discovery originated from a tip by Swiss cybersecurity researcher maia arson crimew. She was indicted by federal prosecutors in 2021 on hacking-related charges but has not been convicted. Exposed files contained dates of birth, home addresses, mobile numbers, headshot photos, and private authentication tokens. Some records also listed spouses and family members as emergency contacts. Dialog collected registrant questionnaires that prompted personal disclosures. The NSC official predicted that future espionage will target behavior more than secrets. Another former Pentagon technology office director warned of domestic terrorism targeting artificial intelligence datacenters. The individual also noted possessing one of Saddam Hussein’s gold-plated AK-47s. The database exposed more than 20 current and former military and intelligence officials. This included a retired U.S. general and a retired official who held a senior security role in Israel and the Palestinian territories.

Origin Energy Discloses Data Breach Affecting 900,000 Customers
On July 28, 2026, Origin Energy, a major Australian energy company, publicly confirmed a significant data breach impacting approximately 900,000 current and former customers. The breach led to unauthorized access and exfiltration of personally identifiable information (PII), including names, addresses, dates of birth, phone numbers, account details, and partial payment information such as the last four digits of credit cards or the BSB and last three digits of bank accounts. Origin Energy first identified a potential security threat in early July 2026, which was initially not deemed credible. However, new information on July 22, 2026, confirmed a security incident had occurred, prompting immediate action and notification of authorities. An alleged hacker provided a media outlet with a sample of 50 customer records and screenshots of internal Origin Energy systems, corroborating the data exfiltration. The incident is currently under investigation by Australian authorities, including the Australian Cyber Security Centre, the National Office of Cyber Security, the Australian Federal Police, and the Office of the Australian Information Commissioner. The specific technical vector used for initial access remains undisclosed.
