Booking.com has confirmed unauthorized access to its systems that exposed guest reservation data including names, email addresses, phone numbers, postal addresses, booking details, and any messages shared with accommodation providers. The company began emailing affected customers over the weekend but did not send alerts via the Booking.com app, creating confusion about whether the notification emails were legitimate. Booking.com says financial data was not accessed. The company has reset PIN numbers for affected reservations. The number of impacted users has not been disclosed, though Booking.com lists 6.8 billion bookings since 2010 across 30+ million properties. Reddit users are already reporting scam messages from people who appear to have real reservation details, suggesting attackers are using the stolen data for targeted phishing. The Register notes this follows a similar 2021 breach pattern where attackers compromised hotel staff logins to access the platform.
The European Commission cloud hack we first reported on March 29 is far worse than initially disclosed. CERT-EU now confirms TeamPCP used an AWS API key stolen through the Trivy supply chain attack to breach the Commission's Amazon cloud environment on March 10 - five days before anyone noticed. The stolen data includes personal information, usernames, and 52,000 email files across 71 hosted clients: 42 internal Commission departments and at least 29 other EU entities. ShinyHunters published the full 340GB dataset on their leak site.
Telehealth giant Hims & Hers - nearly $1 billion in annual revenue, millions of subscribers - disclosed that hackers stole customer support tickets from its Zendesk instance between February 4-7. The ShinyHunters extortion gang conducted the breach by compromising Okta SSO credentials through social engineering, then pivoting into the Zendesk platform. Stolen data includes names, contact information, and details from support requests. No medical records or doctor communications were compromised. The company took two months to disclose.
Healthcare software company CareCloud disclosed to the SEC that hackers breached one of its six electronic health record environments on March 16, gaining access to patient medical data for approximately eight hours. The company serves over 40,000 healthcare providers. It's still investigating whether data was exfiltrated, but classified the incident as material on March 24 due to the sensitivity of the records. No ransomware group has claimed the attack.
Hackers broke into the European Commission's Amazon Web Services account and reportedly stole over 350GB of data, including databases and employee information. The breach was discovered on March 24 and affected the cloud infrastructure hosting Europa.eu websites. The Commission says its internal systems weren't impacted. The attacker isn't demanding ransom - they plan to publish the data instead.
