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.

While the data breach was disclosed two weeks ago, the US Department of Health and Human Services (HHS) has now disclosed the number of affected individuals.

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.
