atadler.com.sg Listed by safepay Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
atadler.com.sg was listed by the safepay ransomware group on 13 January 2026 after internal files were exfiltrated in a ransomware attack; the actual date of the intrusion remains unknown. Individuals who may have shared data with the organisation are advised to monitor their accounts and consider changing passwords or enabling additional authentication steps.
Inside the incident
Available details state only that atadler.com.sg appears on a safepay listing dated 13 January 2026 and that internal files were removed from the organisation’s systems. No confirmed figures for the volume of data, the duration of any unauthorised access, or the method of initial compromise have been released. The organisation has not issued a public statement confirming or disputing the listing.
The group behind it: safepay
Safepay is a ransomware operator that deploys encryption on targeted networks and frequently removes copies of data before demanding payment. The group maintains a public site where it lists organisations it claims to have compromised, using these listings to pressure victims. In this case the group claims to hold material from atadler.com.sg; independent verification of that claim has not been published.
atadler.com.sg and its sector
atadler.com.sg is a Singapore-registered partnership that provides accounting, auditing and bookkeeping services. Firms of this type routinely process financial records, tax filings and payroll information belonging to client businesses and individuals. A successful intrusion at such an organisation can therefore expose data that extends beyond the firm itself to its clients.
What data was at risk
The only description released so far refers to “internal files exfiltrated in ransomware attack.” No inventory of file types, client names or record categories has been made public. Organisations in the accounting sector commonly hold bank details, identification documents, tax returns and correspondence; whether any of these categories were among the files removed from atadler.com.sg is unconfirmed.
Why it matters
Accounting practices hold concentrated sets of financial and identity information. Exposure of such records can enable targeted fraud, tax-related identity theft or unauthorised access to client bank accounts. For the firm, the incident may also affect professional obligations regarding client confidentiality under Singapore’s regulatory framework for accounting services.
If your data was in this claimed breach
Individuals who are clients of atadler.com.sg or who have shared financial information with the firm should monitor their bank and tax accounts for unusual activity. Enabling multi-factor authentication on any associated online services and reviewing recent credit reports are standard first steps.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
