Superintendencia Nacional de Fiscalización Laboral Listed by blackshrantac Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

People whose personal or employment information sits with Peru’s labour inspectorate may now face uncertainty about whether that data has been taken. On 12 November 2025 the Superintendencia Nacional de Fiscalización Laboral, known as SUNAFIL, appeared on a ransomware group’s leak site. Public detail is limited: the number of people affected remains unknown and the precise contents of any stolen material have not been independently confirmed. For workers, employers and inspectors who interact with the agency, the practical question is what information may now be circulating and what steps can reduce the risk of misuse.

This article sets out only what has been reported, places the listing in the context of the group that claimed responsibility, and explains why a breach at a labour-enforcement body carries concrete consequences for ordinary people.

What happened

On 12 November 2025 the Superintendencia Nacional de Fiscalización Laboral was listed by the ransomware group blackshrantac. The group claims that internal files were exfiltrated in a ransomware attack. No further technical details—such as the date the intrusion began, the method used, the volume of data taken, or whether systems were encrypted—have been made public. The number of people whose information may be involved is unknown. At present the listing itself is an unverified claim by the group; independent confirmation of the breach’s full scope has not been released.

The group behind it: blackshrantac

Blackshrantac is a ransomware operation that follows the now-common double-extortion model: it encrypts systems and simultaneously steals data, then threatens to publish the material if a ransom is not paid. The group maintains a leak site where it posts victim names and, in some cases, samples of stolen files to pressure organisations. Like other ransomware crews, it typically targets entities that hold large volumes of sensitive records and that may feel strong pressure to restore operations quickly. Public reporting has associated blackshrantac with attacks across multiple sectors and countries, though each listing must be treated as a claim until verified. In this instance the group asserts that it obtained internal files from SUNAFIL; no additional statements specific to this victim beyond that listing have been provided in the available facts.

Superintendencia Nacional de Fiscalización Laboral and its sector

SUNAFIL is a Peruvian government agency charged with promoting, supervising and enforcing labour rights. It oversees compliance with labour laws and occupational health and safety standards, and it works to encourage formal employment by providing information to workers and employers. In practice this means the agency routinely handles records related to inspections, complaints, workplace conditions, employer registrations and worker identities. Government labour inspectorates sit at the intersection of public administration and private-sector employment data; a compromise of their systems can therefore expose both official correspondence and personal information belonging to large numbers of citizens and businesses. Because the agency’s mandate covers working conditions across Peru, any successful intrusion carries implications that extend beyond a single office.

What data was at risk

The available facts state only that internal files were exfiltrated in a ransomware attack. Exact data types, file counts and categories of personal information have not been disclosed. Organisations of this kind typically hold inspection reports, complaint files, employer and worker contact details, identity documents, occupational-safety records and internal administrative documents. Whether any of those categories were among the material claimed by blackshrantac remains unconfirmed. Until official inventories or forensic findings are released, the precise contents of the stolen data cannot be stated as fact.

Why it matters

For individuals, the risk is that personal identifiers, employment histories or complaint details could be used for identity fraud, targeted phishing or social-engineering attempts that appear to come from a legitimate labour authority. Employers whose inspection or compliance records were taken may face similar exposure of commercial or operational information. For the agency itself, the incident can disrupt inspection work, erode public trust and require costly recovery and notification efforts. Because labour-enforcement bodies often hold data that is both sensitive and long-lived, the consequences of unauthorised access can persist well after systems are restored. The absence of confirmed numbers does not reduce the need for caution among anyone who has interacted with SUNAFIL.

Were you affected?

If you have filed a complaint, undergone an inspection, or otherwise shared personal or employment information with SUNAFIL, treat the possibility of exposure seriously even though the scale remains unknown. Monitor financial and government accounts for unusual activity, be sceptical of unexpected messages that reference labour matters, and consider placing fraud alerts with relevant credit or identity-protection services where available. You can also run a free exposure scan of your email address to check whether that address has already appeared in known breach data sets. Official updates from SUNAFIL or Peruvian authorities, when published, should be the primary source for confirmation of what was taken and who is affected.
