In the next step of the video, we will analyze in more details the incident and the impact it had on Direction générale des étrangers en France (DGEF) and their customers.

On 01 January 2026, Office Français de l’Immigration et de l’Intégration (OFII) disclosed Data Breach issues under the banner "Massive Data Breach at OFII (Office Français de l’Immigration et de l’Intégration)".

A hacker published a database containing over 2.1 million lines of personal information exfiltrated from the official portal of the Administration Numérique des Étrangers en France (ANEF).

The disruption is felt across the environment, affecting ANEF portal (etrangers-en-france.interieur.gouv.fr), and exposing 2.1 million records (1 GB of data), with nearly 2,100,000 records at risk.

In response, and stakeholders are being briefed through Advisories to affected users (unofficial).

The case underscores how Ongoing (unconfirmed by authorities), and recommending next steps like Affected individuals should monitor for phishing attempts, identity theft, and unauthorized communications. OFII should conduct a thorough security audit of the ANEF portal, with advisories going out to stakeholders covering Government agencies and affected individuals advised to remain vigilant.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), with evidence including aNEF portal (etrangers-en-france.interieur.gouv.fr) targeted, and vulnerability exploited such as null (implies potential unknown exploit) and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating attack vector such as Unknown (not disclosed) but implies possible account misuse. Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials in Files (T1552.006) with moderate confidence (50%), supported by evidence indicating highly sensitive administrative data accessed (implies potential credential exposure). Under the Collection tactic, the analysis identified Data from Information Repositories (T1213) with high confidence (90%), supported by evidence indicating 2.1 million records exfiltrated from ANEF portal database. Under the Exfiltration tactic, the analysis identified Exfiltration Over Web Service: Exfiltration to Cloud Storage (T1567.002) with moderate to high confidence (80%), supported by evidence indicating 1 GB of data published on a dark web forum (BreachForums) and Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating data exfiltration such as Yes (implies C2 or direct exfiltration). Under the Impact tactic, the analysis identified Data Destruction (T1485) with lower confidence (30%), supported by evidence indicating potential disruption to OFII services (implied by breach scale) and Data Encrypted for Impact (T1486) with lower confidence (10%), supported by evidence indicating data encryption such as null (no evidence of ransomware). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
