France Titres (Agence nationale des titres securises, ANTS), the French government agency responsible for issuing driver's licenses, national ID cards, passports, and immigration documents, has confirmed a security incident on the ants.gouv.fr portal. The agency detected the compromise on April 15 and published an acknowledgment April 20, saying individual and professional account data may have been exposed. On April 16, a threat actor using the alias 'breach3d' claimed responsibility on a hacker forum, alleging theft of up to 19 million records. The attacker says the stolen data contains full names, contact details, birth data, home addresses, account metadata, gender, and civil status. ANTS operates under the French Ministry of the Interior and is the authoritative source for official French identity documents, making any data leak a foundational risk for downstream phishing, social engineering, and identity fraud. The agency has notified France's data protection authority (CNIL), the Paris Public Prosecutor, and national cybersecurity agency ANSSI. ANTS is telling users no action is required but to exercise 'extreme caution' with any SMS, phone calls, or emails claiming to come from the agency - the stolen data is ideal raw material for targeted impersonation scams.
Backfill from April 21: Anthropic confirmed an unauthorized Discord group quietly accessed Mythos - the company's most powerful AI cybersecurity tool, restricted to about 40 vetted partners including Apple, Microsoft, and Google. The group got in on the same day Mythos was announced (April 7) by piggybacking on a member who works at one of Anthropic's third-party contractors, then guessed the model's URL based on naming patterns from previously leaked information. Anthropic says the group used Mythos to build websites, not for attacks - but they had quiet access for two weeks. Mozilla used Mythos to find and patch 271 Firefox bugs.
On April 20 a threat actor using the alias 'dylanmarly' posted 12.6 GB of stolen data from Mexican cybersecurity firm BePrime, claiming compromise of admin accounts that had no MFA enabled. The dump includes plaintext credentials, financial transaction records, security audit and pentest reports detailing client vulnerabilities, plus API keys for 1,858 Cisco Meraki network devices and live surveillance camera feeds. Affected clients include Iberdrola (Spanish energy giant), ArcelorMittal, Whirlpool, and Alsea (Latin American operator of Starbucks, Domino's, Vips). BePrime then announced legal action against journalists reporting on it.
Cloud development platform Vercel disclosed a security incident on April 19 after a threat actor claiming to be ShinyHunters posted stolen data for sale on a hacking forum. Vercel CEO Guillermo Rauch confirmed the initial access came through a breach at Context.ai, an enterprise AI platform one Vercel employee had signed up for using their Vercel enterprise account with 'Allow All' OAuth permissions. Attackers compromised Context.ai, stole the OAuth token, took over the employee's Google Workspace account, and pivoted into Vercel environments. Once inside, they accessed environment variables not marked as 'sensitive' - these are stored unencrypted at rest, unlike sensitive env vars which Vercel encrypts. The attacker posted 580 employee records (names, emails, account status, activity timestamps) as a teaser, plus screenshots of an internal Vercel Enterprise dashboard. They claim to also have access keys, source code, database data, and API keys, though Vercel characterizes impact as a 'limited subset' of customers. Mandiant is engaged. This is the cleanest real-world example to date of the AI supply chain risk pattern everyone has been warning about: a third-party AI tool with broad OAuth scopes becomes the initial access vector into your primary infrastructure.
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.
ShinyHunters breached Anodot, an AI-based data anomaly detection platform acquired by Glassbox in late 2025, and stole authentication tokens that connected Anodot to its customers' cloud environments. Using those tokens, the attackers accessed Snowflake data warehouses belonging to over a dozen companies and began exfiltrating data last Friday - timed to the Easter/Passover holiday for maximum dwell time. ShinyHunters also attempted to use the stolen tokens against Salesforce instances but were blocked by AI detection. The group is now extorting affected companies, demanding ransom payments to prevent data release. Anodot's customer list includes Puma, SAP, T-Mobile, and UPS. This is the same playbook ShinyHunters used in the 2025 Snowflake campaign and the Gainsight/Salesforce attacks - breach a trusted integration, not the platform itself.
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.
The TeamPCP supply chain campaign has claimed its biggest victim yet. Attackers used credentials stolen from the Trivy vulnerability scanner compromise to breach Cisco's internal development environment, stealing source code belonging to both Cisco and its customers. Multiple AWS keys were also taken and used for unauthorized activity across Cisco's cloud accounts. The company expects continued fallout from the follow-on LiteLLM and Checkmarx compromises in the same campaign.
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.
