Has leakbase.la been linked to any major data breaches or exposed databases?
Executive summary
Leakbase.la has repeatedly appeared in public reporting as a repository and propagation point for large leaked datasets and forum activity tied to the LeakBase actor, with security firms and trackers documenting multiple high‑impact disclosures advertised or hosted via the site or its operators [1] [2] [3]. That said, some listings originate from forum posts or aggregated trackers rather than forensic confirmation from breached organizations, so attribution and technical provenance vary across incidents [1] [4] [3].
1. Leakbase.la as a hosting/republishing hub — documented instances and security reporting
Multiple incident trackers and security outlets show leaked or claimed datasets being shared on Leakbase.la, from regional political lists to millions‑row consumer databases; these include reporting that Leakbase.la republished a massive X/Twitter tranche in 2025 and hosted large MYM.Fans and Free.fr datasets according to aggregated breach trackers [1] [4] [5]. Independent security analyzers such as Cyble and CSIDB have also linked the LeakBase actor — which historically operated on BreachForums and other cybercrime forums — to specific high‑impact disclosures like the Swachh City leak affecting millions, and note that the actor and forum ecosystem have been used to distribute compromised datasets [2] [6] [3].
2. Distinguishing forum claims from verified breaches — where reporting is strong and where it is weaker
Some of the strongest public signals tying LeakBase/Leakbase.la to major exposures come from security firms and incident databases that traced specific datasets back to posts by the actor, for example Cyble’s analysis of the Swachh City disclosure and CSIDB’s cataloguing of repeated public dumps tied to LeakBase activity [2] [3]. Conversely, other listings on aggregators and blogs are derived from forum posts or dark‑web sightings — for example large archives posted on Leakbase.la or BreachForums — and those sources sometimes lack independent confirmation from the affected organizations, leaving technical provenance or the cause of compromise unconfirmed [1] [4].
3. Reputation, malicious signals, and marketplace behavior tied to the domain
Beyond hosting or reposting data, security tooling and URL scanners flag leakbase.la as suspicious or associated with malicious activity, and domain‑reputation analyses emphasize opaque ownership and rapid domain churn that are consistent with dark‑web marketplace behavior [7] [8]. Analysts and dark‑web monitors describe LeakBase as part of an ecosystem that monetizes and trades SQL dumps, CRM access, and large collections of PII — activity that increases likelihood Leakbase.la will surface sizeable exposed datasets, whether new or previously sold elsewhere [9] [10].
4. Geographic and actor patterns — what the record shows about targets and scale
Open reporting and intelligence databases indicate a pattern: LeakBase‑branded activity has repeatedly targeted government and civic platforms and aggregated large volumes of personal data (Swachh City, Penang government, Tisza Világ political lists), while other posts promoted tens of millions of rows or national ISP customer datasets on Leakbase.la or affiliated forums [3] [5] [4]. These patterns suggest the site is frequently used as a distribution vector for both targeted government data and broad consumer datasets, though the degree of direct operational control by the same actor across all incidents is not always spelled out in the sources [3] [4].
5. What can reasonably be concluded right now
It is well documented that Leakbase.la and the LeakBase actor have been linked in open reporting and dark‑web monitoring to multiple major data disclosures and large database postings, with credible security firms and incident trackers citing specific leaks and dataset postings [2] [3] [1]. At the same time, some claims circulate primarily as forum posts or aggregator listings without confirmed incident response or forensic attribution from affected organizations, so the underlying cause (insider theft, misconfiguration, prior sale) and the exact technical provenance are not uniformly validated in the public record [1] [4].
Conclusion
The preponderance of public reporting and dark‑web monitoring ties leakbase.la and the LeakBase actor to multiple major exposed databases and high‑volume data dumps, but readers should treat individual listings with caution until vendors or breached parties confirm scope and vector; security firms like Cyble and databases such as CSIDB provide the most concrete, attributed examples in the available reporting [2] [3] [1].
