Breach Intelligence Summary
Entity: IndiHome · Actor: Unknown · Sources: 3 references
Attack: Unknown
Profile: Company · Telecommunications and internet services · Broadband provider · Indonesia
Timeline: Breach (2019-11-01) · Indexed (Nov 27, 2023) · Year (2019)
Exposure: 12.6M records · 6 fields: Device Information, Email Address, Full Name, Gender, Geographic Location, IP Address
Status: Disputed
Executive Summary
In 2021-2022, a dataset attributed to IndiHome surfaced on a hacking forum, spanning roughly 26.7 million rows with 12.6 million unique email addresses and data stamped through November 2019. Beyond names, IP addresses, genders, and geographic locations, the dataset notably contained customer browsing history (visited sites and timestamps) and national identity numbers. Telkom Indonesia disputed the authenticity of the data.
ObscureIQ assessment: Browsing-history exposure tied to real identities and national IDs is unusually sensitive because it reveals private interests and activity; the company dispute means attribution and scope remain contested.
Breach Impact
If accurate, the pairing of identity and national ID with detailed browsing history is highly invasive, enabling behavioral profiling, de-anonymization, and targeted manipulation far beyond typical credential exposure.
