European DIY e-commerce platform ManoMano disclosed a large-scale data breach after threat actors compromised a third-party customer service provider (subcontractor), leading to the unauthorized extraction of customer data tied to accounts and support interactions. The incident was identified in January 2026 and affects roughly 38 million customers across ManoMano’s European markets; the company reported no evidence that its internal systems were altered and stated that passwords were not accessed.
Reportedly exposed data varies by customer but includes names, email addresses, phone numbers, and customer service communications (including support tickets and potentially attachments). A threat actor using the alias “Indra” claimed responsibility on a hacker forum and alleged possession of approximately 37.8 million user records, a figure broadly consistent with ManoMano’s notification, though the claim has not been independently verified. ManoMano said it blocked the compromised account, revoked the subcontractor’s access, and implemented enhanced access controls while continuing its investigation.

In late February 2026, ManoMano notified roughly 38 million customers that a third-party vendor breach had exposed personal data including names, email addresses, phone numbers, and customer service communications. The company said passwords were not accessed, there was no evidence of data modification, and the investigation was ongoing.
In February 2026, a BreachForums user using the alias "Indra" claimed responsibility for the breach and alleged possession of data on about 37.8 million users, along with support tickets and attachments. These claims were reported publicly but not independently verified.
After detecting the incident in January 2026, ManoMano blocked the compromised account the same day, revoked the subcontractor's access, and strengthened access controls and monitoring. The company also notified French authorities including CNIL and ANSSI, with some reports also mentioning the Cyber Emergency Île-de-France platform.
In January 2026, ManoMano discovered that attackers had used a compromised account belonging to a third-party customer support subcontractor to access and download customer data. Reporting indicates the access may have involved the subcontractor's Zendesk environment rather than ManoMano's core systems.
