PT Perusahaan Jamu Air Mancur Listed by Coinbase Cartel Ransomware Group

The ransomware group Coinbase Cartel has listed PT Perusahaan Jamu Air Mancur on its leak site. According to the listing, the Indonesian herbal medicine manufacturer appears among the group’s claimed victims. The company has not publicly confirmed the claim as of writing.

This means the only information currently available comes from the attacker’s own publication. No independent verification exists. The record does not name any specific categories of information, does not state how many people may be affected, and provides no incident date — only the filing date of August 22, 2026. Because nothing has been confirmed, you cannot yet know whether any of your records with the company were involved.

What a Leak-Site Listing Actually Establishes

Ransomware and extortion groups frequently publish names of companies on dark-web leak sites as a pressure tactic to demand payment. These listings are marketing material produced by the attacker. They are cheap to create and sometimes include recycled data from older incidents, exaggerated claims, or companies that never suffered a breach at all.

In many documented cases, organisations named on such sites later prove the claim was false, or the data shown was already circulating years earlier. A listing alone does not constitute evidence that files were taken, that any particular records were compromised, or that the company’s systems were even accessed. Real confirmation would require an admission by the company, a regulatory filing with detailed findings, or forensic evidence released by a credible third party. Until one of those appears, the safest position is to treat the claim as unverified.

The Current Pattern in Ransomware Extortion

Coinbase Cartel and similar crews have increasingly targeted small and medium-sized businesses in non-technology sectors, including manufacturers, distributors, and traditional industries. Publishing an unverified listing costs the group almost nothing while creating immediate reputational pressure on the named organisation. This tactic deliberately blurs the line between real intrusions and theatre. For you, it means that every new leak-site appearance must be judged on its own evidence rather than accepted at face value. The absence of detail in this particular record — no categories listed, no scale given, no incident date — is common in these publications and leaves you with more questions than answers.
