sipicorp.com Listed by blackbasta Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 22, 2023, the ransomware group blackbasta listed sipicorp.com on its leak site, claiming to have exfiltrated internal files from Sipi Metals Corp., also known as Sipi Corporation. Public detail remains limited to the group's own posting, which describes a 145 GB collection of material and does not state the number of people affected or the full scope of any intrusion.

The listing matters because Sipi operates in the refining, recycling and reuse of valuable materials, a sector that routinely handles sensitive commercial, financial and personnel records. Until independent verification appears, the claims stand as assertions by the threat actor rather than What's Publicly Reported.

Inside the incident

According to the blackbasta listing dated December 22, 2023, the group claims to have taken approximately 145 GB of data from sipicorp.com. The post identifies the victim as Sipi Metals Corp., with an address at 1720 N. Elston Avenue, Chicago, Illinois 60642-1579, and quotes the company's own description of its century-long role in refining, recycling and reusing valuable materials. The claimed contents are listed as users' personal folders, accounting material, corporate documents and similar items. No further technical details—such as the initial access method, the precise date of any intrusion, or whether systems were encrypted—have been disclosed in the available record. The number of people affected is unknown.

The group behind it: blackbasta

Blackbasta is a ransomware operation that became publicly active in 2022 and has since been associated with double-extortion attacks: encrypting systems while also exfiltrating data and threatening to publish it. The group typically posts victim names and sample file lists on a dedicated leak site to pressure payment. Its targets have spanned manufacturing, professional services and other commercial sectors. In this case the listing of sipicorp.com is presented solely as the group's claim; no independent confirmation of the intrusion or the data volume has been supplied in the public facts. Blackbasta's standard practice is to release further material if negotiations fail, but whether that has occurred here remains unconfirmed.

sipicorp.com and its sector

Sipi Corporation, operating as Sipi Metals Corp., describes itself as a long-established firm engaged in refining, recycling and reusing the world's most valuable materials. Companies of this type sit at the intersection of industrial metals processing, scrap recovery and commodities trading. They typically maintain detailed records of suppliers, customers, inventory valuations, regulatory compliance filings and employee information. A breach affecting such an organisation can therefore touch both commercial confidentiality and personal data held for staff or business partners. The Chicago address listed by the group places the firm within a major U.S. industrial corridor, underscoring the potential reach of any exposed operational records.

What data was at risk

The blackbasta post states that the exfiltrated material consists of internal files totaling 145 GB and specifically names users' personal folders, accounting records, corporate documents and related items. Exact contents beyond those categories are not disclosed, and no independent inventory has been released. Organisations in metals refining and recycling commonly hold employee contact and payroll data, financial ledgers, contracts, shipping and inventory logs, and proprietary process information. Whether any of those specific categories were present in the claimed 145 GB set remains unconfirmed; the only named categories are those supplied by the group itself.

Why it matters

If the claimed data were authentic and subsequently published, individuals whose personal folders appear in the set could face risks of identity misuse, targeted phishing or exposure of private correspondence. Accounting and corporate documents could reveal pricing, supplier relationships or financial positions that competitors or fraudsters might exploit. For the organisation, the incident raises the prospect of operational disruption, regulatory scrutiny and loss of commercial confidence, even if the full extent of the intrusion is still unverified. Because the number of affected people is unknown, the practical impact cannot yet be quantified, but the combination of personal and financial material makes careful monitoring advisable for anyone connected to the firm.

Were you affected?

Anyone who has worked with or for Sipi Metals Corp., or who has shared personal or financial information with the company, should treat the blackbasta claim as a prompt for caution. Monitor bank and credit accounts for unusual activity, be alert to unexpected emails or calls that reference company details, and consider placing fraud alerts with credit bureaus if you believe sensitive data may be involved. Readers can also run a free exposure scan of their email address to check whether their information has already surfaced in known breach data sets. Official notifications, if any are issued by the company or regulators, will provide the most reliable guidance on next steps.
