Indonesia's Customs Analytics Platform Listed by everest Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Indonesia's Customs Analytics Platform was listed by the everest ransomware group on April 28, 2026, after internal files were exfiltrated in a ransomware attack. An undisclosed number of individuals may have been affected; check official channels and change any credentials or access tokens that could have been exposed.
Breaking down the breach
The incident was first noted publicly through the everest group's leak-site posting on April 28, 2026. The only confirmed element from available records is the group's assertion that internal files were taken during a ransomware operation. No independent confirmation of the attack, timeline of events, or method of initial access has been made public. The number of records or individuals involved is listed as unknown.
Who is everest?
Everest is a ransomware operation that has appeared in public reporting since at least 2020. The group follows a double-extortion model in which data are encrypted on victim systems and copies are also removed for later publication if a ransom demand is not met. It maintains a leak site where claimed victims are listed, along with samples of data or descriptions of stolen material. The group has been linked in open-source reporting to attacks on entities in multiple countries and sectors, though each listing remains an unverified claim by the operators until corroborated by the victim or investigators.
Who is Indonesia's Customs Analytics Platform?
Indonesia's Customs Analytics Platform supports the country's customs administration by processing trade-related data and analytics. Organisations of this type routinely handle shipment records, importer and exporter identifiers, tariff classifications, and declarations tied to cross-border movement of goods. A breach affecting such a platform is consequential because the data involved can include details used for regulatory compliance, revenue collection, and supply-chain oversight across national borders.
What was likely exposed
The only data type referenced in connection with the listing is internal files exfiltrated during the claimed ransomware attack. No further breakdown of file categories or record counts has been disclosed. Organisations that manage customs analytics commonly hold commercial documentation and identifiers linked to individuals or companies engaged in international trade, yet the precise contents of the exfiltrated material in this case remain unconfirmed.
- Internal files (as stated in the group listing)
- Exact data categories and volume: undisclosed
The real-world impact
Exposure of internal customs files could create operational disruption for the agency and potential follow-on risks for businesses whose trade records were involved. Individuals named in declarations or related documentation may face secondary risks such as targeted fraud or misuse of personal or commercial identifiers. The absence of Reported Details on scale means the extent of any downstream effects cannot yet be quantified.
Were you affected?
Individuals or businesses that have submitted customs declarations or trade documentation to Indonesian authorities can monitor official channels for any future notifications. A practical first step is to review recent correspondence from customs or logistics providers for any unusual activity. Readers can also run a free exposure scan of their email address against known breach data sets to check for prior appearances of their information.

Publicly posted by everest — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
