Ciclo Cairu Listed by Sarcoma Ransomware Group

If you are a customer of Ciclo Cairu, here’s what is being claimed, and what it would mean for you.

Ciclo Cairu began its activities in 1985 in the city of Pimenta Bueno, Rondônia, selling bicycle parts, repairs and renovations at retail. A small bicycle workshop like many that can be seen in every city. Almost two years later, taking advantage of the great lack of parts suppliers in the replacement market, its owners decided to enter the wholesale bicycle parts sales business, initially supplying other small traders in the sector in nearby cities, an activity that, conducted with a lot of work, seriousness and respect for customers, was very successful and developed rapidly, reaching the en
— from Sarcoma’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

Ciclo Cairu Listed by Sarcoma Ransomware Group

On October 09, 2024, Brazilian bicycle-parts wholesaler Ciclo Cairu appeared on the leak site of the sarcoma Ransomware Group. The listing states that internal files were exfiltrated during a ransomware attack. The company, which began in 1985 as a small workshop in Pimenta Bueno, Rondônia, has grown into a regional supplier serving retailers across multiple states. The sarcoma leak site does not disclose the volume of data taken, the exact types of records involved, or any ransom demand.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

Primary Disclosure Details

The sarcoma leak site entry, first indexed on October 09, 2024, states that internal files were exfiltrated following a ransomware deployment. No customer record count is published, and the notification does not specify whether personal data such as names, addresses, tax IDs, or payment information was included. The disclosure consists solely of the company name, the actor’s branding, and a statement that data was allegedly stolen prior to encryption. Public copies of the leak page, hosted via ransomware.live at the provided link, remain the sole primary source.

Why This Matters for You and Your Family

When a regional supplier like Ciclo Cairu suffers a breach, anyone who has ordered parts, opened an account, or supplied documents for credit terms may have information now in criminal hands. Even if the leak site does not list exact data types, ransomware operators routinely harvest employee payroll files, customer invoices, supplier contracts, and email archives. If your name, address, phone number, or government-issued identifier appears in any of those files, it can be sold or published without further warning. For ordinary families this translates into sudden spikes in phishing calls, identity-theft attempts, and fraudulent loan applications months after the initial breach.

Doxxing and Identity-Chain Risks

Stolen internal files frequently contain spreadsheets that link customer emails to physical addresses, phone numbers, and sometimes tax IDs. Threat actors chain this information with credential leaks from other breaches to map online handles to real-world identities. A single exposed email can unlock gaming accounts, social-media profiles, and family photos. Children’s gaming accounts are especially vulnerable because parents often reuse passwords or security questions derived from family details that appear in business records. Once an attacker controls one account, they can pivot to others, escalating from data theft to full doxxing.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
