Co-opbank Pertama Listed by suncrypt Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Co-opbank Pertama Listed by suncrypt Ransomware Group (reported April 24, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
The only confirmed public record is the appearance of Co-opbank Pertama on the suncrypt leak site on the reported date. The group claims to have stolen internal data in a ransomware attack. No further details on the timing of the intrusion, the volume of data, or the method of access have been disclosed in available records.
Who is suncrypt?
Suncrypt is a ransomware group that emerged publicly in 2021 and follows a double-extortion model. It typically encrypts victim systems and exfiltrates data, then posts samples or file listings on a dedicated leak site when ransom demands are not met. The group has claimed responsibility for incidents against multiple organizations across different sectors. Its listings represent assertions by the actor rather than independently verified events unless corroborated by the victim or investigators.
About Co-opbank Pertama
Co-opbank Pertama operates as a cooperative bank, providing financial services to members within its cooperative framework. Institutions of this type routinely process account information, transaction records, loan documentation, and customer identification data. A breach at such an organization can affect both operational records and personal financial information held on behalf of customers.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been published. Cooperative banks commonly store customer names, account numbers, transaction histories, and identity documents, but the exact contents of the claimed exfiltration remain unconfirmed.
Why it matters
Exposure of internal banking files can create long-term risks of fraud or identity misuse for individuals whose records were present. For the organization, the incident may lead to regulatory scrutiny, operational disruption, and costs associated with investigation and remediation. Because the number of affected people is unknown, the full scale of potential impact cannot yet be assessed from public information.
If your data was in this claimed breach
Monitor bank and credit statements for unusual activity and consider placing fraud alerts with credit reporting agencies. Use strong, unique passwords and enable multi-factor authentication on financial accounts. Readers can run a free exposure scan of their email address against known breach data to check for appearances in previously published datasets.

Publicly posted by suncrypt — 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.
