Jesin Group
About the organisation
Jesin Group is a prominent property developer in Northern Malaysia with over 50 years of experience, specializing in residential and commercial real estate development, construction, and asset management.
What the listing means
Jesin Group appeared on the lamashtu leak site on 20 April 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated. This group has not published new claims in the last 30 days.
Recommended actions
- Treat any unsolicited message referencing Jesin Group as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on jesin.com.my, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Construction 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.
