About the organisation

The platform provides comprehensive drug information — including dosages, interactions, clinical guidelines, and prescribing data — for healthcare professionals across the globe. MIMS operates internationally across Asia, Australia, and beyond, with dedicated editions for countries including Malaysia, India, Indonesia, Japan, Singapore, and many others. Its mobile app and online database are used daily by doctors and pharmacists for drug lookups, medical news, and CME articles
What the listing means
MIMS appeared on the thegentlemen leak site on 06 May 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated — the attack itself is dated 27 April 2026, 8 days before the listing. This group has published 134 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing MIMS as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on mims.com, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Business Services organisations should review this group's known TTPs and validate detection coverage against them.
- Watch for follow-on extortion: stolen data is often re-leaked or resold after the initial listing.
- A leak-site listing is a claim made by the attacker, not a confirmed breach — check the organisation's own disclosures before acting on it.
