Overseas Express Shipping Company

Overseas Express Shipping Company (OESC) operates as an international express shipping and logistics provider. The company is headquartered in Croatia. Its name indicates a focus on overseas shipments, suggesting services that cross international borders. As an express carrier, OESC likely handles time‑sensitive parcels and documents for businesses and individuals. The firm serves markets that require rapid delivery across continents, though specific geographic reach is not detailed in the source material. Being based in Croatia positions it within a European logistics hub that connects to Mediterranean and global trade routes.

In September 2020, OESC suffered a ransomware attack carried out by the LockBit group. The attackers exfiltrated a database containing approximately 5.8 million records of personal information. The leaked data included names, addresses, and email addresses of individuals. LockBit used dark‑web forums and a dedicated blog to publicize the breach and pressure the company for a ransom payment. Technical shortcomings in the ransomware’s encryption and decryption processes reportedly allowed some affected organizations to recover without paying. The incident highlighted both the group's reliance on data‑theft extortion tactics and the operational inconsistencies that can undermine ransomware effectiveness.
