Mexican Government Listed by losttrust Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

When a national government appears on a ransomware group's leak site, the practical concern is straightforward: internal files may have left official systems and could include material that touches citizens' dealings with the state. On 26 September 2023 the Mexican Government was listed by the group known as losttrust, which claimed to have exfiltrated internal files in a ransomware attack. How many people might be affected remains unknown, and public detail on the precise contents is limited.

For ordinary residents, businesses, and anyone who interacts with Mexican public services, the listing raises the possibility that administrative or operational records could surface outside government control. Until more is confirmed, the prudent response is to understand what has been claimed, what is still undisclosed, and what steps reduce personal risk.

Inside the incident

According to the available record, the Mexican Government was listed by the losttrust ransomware group on 26 September 2023. The group’s claim is that internal files were exfiltrated in a ransomware attack. The number of people affected is unknown. No further public detail has been supplied in the record about the intrusion method, the duration of any access, the volume of data taken, or whether encryption of systems occurred alongside the claimed theft.

Because the listing itself is an assertion by the threat actor, it should be treated as an unverified claim unless independently confirmed by the affected organisation or competent authorities. Timing beyond the reported listing date, technical indicators, and any ransom demand details are undisclosed in the material at hand.

Who is losttrust?

losttrust is a ransomware operation that has appeared in public reporting as a group that steals data and threatens to publish it—commonly described as double-extortion tactics—while also deploying encryption in some campaigns. Like other actors in this category, it has used dedicated leak sites to name victims and pressure organisations into paying. Public tracking of such groups typically notes that they target a range of sectors and jurisdictions rather than a single industry.

For this specific case, the only claim tied directly to the Mexican Government is the leak-site listing and the assertion that internal files were exfiltrated. No additional statements by losttrust about this victim—such as sample file lists, deadlines, or ransom figures—are included in the facts provided, and none should be assumed.

Who is Mexican Government?

The Mexican Government is the governing system of the Republic of Mexico, founded in 1824 and headquartered in Mexico City. As the central public authority, it oversees national administration, public services, regulation, and the wide range of records generated by interaction between the state and its citizens, residents, and organisations.

A breach affecting a national government is consequential because such bodies typically hold large volumes of administrative, identity-related, and operational information. Even when only “internal files” are named, the potential reach of any confirmed exposure can extend beyond a single ministry or agency to people who rely on government systems for identification, benefits, taxation, justice, or everyday public services. The scale and sensitivity of that role explain why listings of government entities draw sustained attention.

The information in question

The facts name the exposed material as internal files exfiltrated in a ransomware attack. No further breakdown—such as categories of personal data, employee records, citizen databases, or classified versus routine administrative documents—is provided. The number of individuals whose information may be involved is unknown.

Organisations of this kind commonly hold identity and civil-registry data, correspondence, internal policy and operational documents, procurement and financial records, and information tied to public services. That is general context only. The exact contents of any files taken in this incident remain unconfirmed in the public record, and it would be inaccurate to treat specific data types as established fact beyond the stated “internal files.”

What's at stake

For people who may be connected to the material, the concrete risks are familiar from other government-related incidents: possible misuse of personal or administrative details if they later appear in criminal markets, targeted phishing that references real government interactions, and longer-term uncertainty about whether particular records were among those taken. For the organisation, stakes include operational disruption if systems were affected, erosion of public confidence, and the resource cost of investigation and remediation—none of which can be quantified from the limited facts available.

In practical terms, affected parties and the wider public face these points of exposure:

• Uncertainty over whether personal or case-related information was among the internal files claimed to have been taken.
• Elevated risk of social-engineering attempts that exploit trust in official communications.
• Limited ability to assess individual impact while the number of people affected and the precise data types remain undisclosed.
• Potential secondary effects if any published material is later reused for fraud or further intrusion attempts against citizens or partner organisations.

Were you affected?

If you have had dealings with Mexican public authorities—identity documents, tax filings, benefits, legal matters, or employment—you cannot yet know from public reporting alone whether your information was involved, because the scale and exact contents are undisclosed. Sensible first steps include monitoring official notices from Mexican government channels, treating unexpected messages that reference government business with caution, and reviewing financial and identity accounts for unusual activity. Where you use email addresses tied to government services, you can also run a free exposure scan of your email to check whether that address has already appeared in known breach data sets. Keep records of any suspicious contact and report confirmed fraud to the appropriate authorities. Public detail on this incident remains limited; further clarity, if it comes, will most usefully come from official statements rather than from the threat actor’s claims alone.
