What Happened
In an apparent data breach involving the Australian accounting firm TheKalculators.com.au (also linked to Synkli), a hacker leaked a database on underground forums like Spear.cx, exposing sensitive client and organizational records including business IDs, client names, emails, phone numbers, TFN (Tax File Numbers), ABN (Australian Business Numbers), postal and residential addresses, trust structures, and relation types; no specific date is confirmed in available reports, though the leak surfaced recently prior to April 2026, and the exact number of records remains undisclosed. The compromised data spans both individual clients (e.g., first/last names, display names, status, created dates) and organizations (e.g., org business IDs, client types, categories), with download links shared publicly on the forum, but the company’s privacy policy and site pages show no official acknowledgment or response.
