Breach Summary
In July 2018, a data breach of the defunct Belgian social network Netlog, dating back to November 2012, was identified. It exposed email addresses and plaintext passwords for a very large number of subscribers (this record reflects ~55.98 million; some reporting cites ~49 million). Netlog had been discontinued in 2015, and the breach went undetected for roughly six years. The credentials are usable for credential stuffing. Threat actor and intrusion method are not reliably established.

About Netlog
Netlog was a Belgian social-networking platform popular across Europe in the late 2000s, letting users build profiles, share content, and connect. It was discontinued in 2015.
Why They Hold Your Data
Legacy social-media platforms collect user accounts, profile data, messages, photos, social connections, and historic engagement records tied to personal networking and online identity.
Recent Developments
Although Netlog shut down in 2015, in July 2018 a data breach dating back to November 2012 was identified, exposing subscriber email addresses and plaintext passwords. As a defunct service, remediation for affected individuals is limited to password-reuse mitigation.

Breach Impact
The exposure of email addresses and plaintext passwords for tens of millions of former Netlog users primarily creates credential-stuffing and account-takeover risk where those passwords were reused elsewhere, plus targeted phishing. Plaintext storage made the credentials immediately usable.
Exploitation & Downstream Threats
• Credential stuffing and account takeover against reused passwords (plaintext, immediately usable) | • Targeted phishing using exposed email addresses
Principal Risk Advisory
What this means for a principal
A social-platform breach: profile and contact-graph data supports impersonation, enrichment and social engineering. For a high-profile principal the main risk is credible impersonation and enrichment of existing exposure.
What You Should Do
- Reset any reused passwords and enable MFA on email first, then financial accounts.
- Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.
How ObscureIQ Can Help
- Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
- Exposure mapping: cross-reference the exposed identifiers against broker-available data to size and prioritize the principal's wider footprint.
- ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
