Berlina Tbk Listed by bianlian Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 22, 2022, the Indonesian plastic-packaging company Berlina Tbk was listed by the ransomware group bianlian. Public reporting states that internal files were exfiltrated in a ransomware attack; the number of people affected remains unknown, and further operational details have not been disclosed.

The listing itself is a claim published by the group. For customers, suppliers, employees and partners of a firm that designs and manufactures packaging at industrial scale, any confirmed exposure of internal material carries practical consequences that warrant clear, factual attention.

What happened

According to the available record, Berlina Tbk appeared on bianlian’s leak site on or around December 22, 2022. The group asserted that it had conducted a ransomware attack and exfiltrated internal files. No public confirmation of the intrusion method, the precise date of initial access, the volume of data taken, or any ransom demand has been released. The number of individuals whose information may be involved is listed as unknown. Beyond the claim of exfiltrated internal files, the contents and scope of the material remain undisclosed in the public account.

Who is bianlian?

Bianlian is a ransomware operation that has been active in the double-extortion model: operators encrypt systems and simultaneously copy data, then threaten to publish the stolen material if payment is not made. The group maintains a leak site on which it names organisations it claims to have compromised and, in some cases, releases sample files or larger archives. Bianlian has previously targeted companies across manufacturing, professional services and other sectors in multiple countries. Its listings are assertions by the actors themselves; independent verification of each claim is not always immediately available. In this instance, the public record consists of the group’s listing of Berlina Tbk and the accompanying statement that internal files were taken.

About Berlina Tbk

Berlina Tbk is described as a provider of one-stop plastic-packaging solutions. Its facilities cover product design and development, tube production, injection moulding, blow moulding, caps, decorations and mould making, supported by industrial-scale technology and machinery. Companies in this sector typically maintain detailed production data, customer and supplier records, technical drawings, quality-control documentation, and internal administrative files. A breach affecting such an organisation can therefore touch commercial relationships, proprietary processes and the personal or business information of people who deal with the firm. Because packaging manufacturers sit in extended supply chains, disruption or data exposure can have downstream effects on brand owners and distributors that rely on the company’s output.

The information in question

The public facts state only that internal files were exfiltrated in a ransomware attack. No inventory of specific data categories—such as employee records, customer lists, financial documents or technical designs—has been released. Organisations of this type ordinarily hold a mixture of operational, commercial and personnel information. Until a fuller accounting is provided by the company or by independent investigators, the exact nature and sensitivity of the material claimed by bianlian remain unconfirmed. Readers should treat any assertion about particular data elements as unverified unless corroborated by official disclosure.

Why it matters

For individuals whose details may appear in internal files, possible risks include unwanted contact, phishing attempts that reference genuine business relationships, or misuse of personal identifiers if such data were present. For the company, exposure of internal material can affect negotiating positions, reveal proprietary methods, or complicate relationships with customers and suppliers. Because the scale of the incident and the precise contents are unknown, the practical impact cannot yet be quantified. What is clear is that ransomware groups routinely monetise stolen data through publication or sale when negotiations stall, so the mere listing raises the possibility that material could circulate beyond the original actors. Calm monitoring of official statements from Berlina Tbk and of any subsequent releases attributed to the group is the appropriate posture while facts remain limited.

If your data was in this claimed breach

If you have a past or present connection to Berlina Tbk—as an employee, contractor, customer or supplier—consider basic protective steps. Monitor financial and email accounts for unusual activity. Treat unsolicited messages that reference the company or packaging contracts with caution, and verify any request for information or payment through known official channels. Change passwords on accounts that may have shared credentials or recovery details linked to work email. Where available, enable multi-factor authentication. Keep records of any suspicious contact. You can also run a free exposure scan of your email address to check whether it has already appeared in known breach datasets; such a check does not confirm involvement in this specific incident but can indicate whether your address is circulating more widely. Continue to follow any formal notifications issued by Berlina Tbk for guidance tailored to this event.
