Chimbusco Listed by avoslocker Ransomware Group

On December 26, 2022, Chinese marine fuel supplier CHIMBUSCO appeared on the leak site of the AvosLocker ransomware group. The listing states that internal files were exfiltrated during a ransomware attack, although the exact number of records and specific data types remain undisclosed by the group.

Details from the Leak Site

The primary disclosure on the AvosLocker leak site, archived via ransomware.live, states that CHIMBUSCO suffered a ransomware incident resulting in data exfiltration. Established in 1972 and now backed by PetroChina and COSCO Group, the company supplies bunker oil, marine lubricants, and fresh water while operating across more than 50 major ports in China with over 100 barges and 30 branch offices. The listing does not quantify affected records, name the precise systems compromised, or reveal the ransom demand. It simply states that internal files were taken and threatens further publication if payment is not made.

Why This Matters for You and Your Family

When a company like CHIMBUSCO that moves fuel through major ports experiences a breach, your personal information may be exposed even if you have never directly done business with them. Suppliers, port workers, vendors, and customers often have their contact details, contracts, invoices, or employee records stored in the very internal files now held by attackers. Internal files exfiltrated can include spreadsheets with names, addresses, phone numbers, email accounts, and financial transaction records. Once these leave the company’s control, they become permanent currency on underground markets, increasing the chance that you or someone in your household will face identity theft, phishing, or account takeover attempts tied to this incident.

The Doxxing and Identity-Chain Risks

Leaked internal files rarely stop at one company. Attackers and subsequent buyers routinely cross-reference newly obtained data with existing breach records to build complete identity profiles. A phone number from a CHIMBUSCO invoice can link to your social-media handles, children’s school records, or gaming accounts. These chains allow criminals to reset passwords, impersonate family members, or launch convincing spear-phishing campaigns. Credential leaks of this nature frequently cascade into account takeovers across unrelated services, turning a single corporate breach into long-term personal exposure for you and your family.

AvosLocker’s Known Track Record

Public reporting attributes the emergence of AvosLocker to mid-2021. The group has targeted organizations across multiple sectors, including healthcare providers, manufacturing firms, and logistics companies. Their typical playbook begins with initial access gained through compromised remote desktop credentials or exploited vulnerabilities, followed by exfiltration of sensitive files before encryption. AvosLocker then posts samples on their leak site and pressures victims with deadlines, often threatening to sell or publish the data if ransom is not paid. The CHIMBUSCO listing fits this pattern, although the precise initial access vector used against this victim has not been publicly detailed.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by the service.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
• Rotate any passwords used at CHIMBUSCO or related vendor portals anywhere they are reused, and switch to 2FA through an authenticator app instead of SMS.
• Cover the entire household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same address or parent email.
• Let remediation specialists manage takedown requests for any exposed personal records across data brokers and leak sites.

The CHIMBUSCO breach illustrates how corporate ransomware incidents create lasting personal risk that does not disappear when the news cycle moves on. One short forward-looking step is to treat every new leak as a prompt to lock down the connections that criminals exploit. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts. Starting that process now limits the damage attackers can do with data taken in December 2022 and any future incidents that follow.
