In August 2021 the organisation experienced a data security breach after receiving a third‑party email that claimed unauthorized access to its IT network. The incident was reported to the relevant authorities. Shortly thereafter the threat actor group ALTDOS claimed responsibility for the breach. Initially ALTDOS’s claims were made without supporting evidence. Later the group supplied a statement and proof of compromise to an independent cybersecurity outlet. However, discrepancies were noted between the group’s initial communication and the later evidence they provided. The breach affected the parent organisation of the subsidiaries OrangeTee & Tie and OrangeTee Advisory. No details about the specific data that may have been exfiltrated or any operational consequences have been disclosed publicly. This episode remains the only publicly known security incident involving the company.
