➤Summary
The Colvanes SAS data leak is an alarming incident now circulating on dark-web forums after a 31 October 2025 post by a user called “OnionGarbage.” The actor claims to be selling more than 400 GB uncompressed (around 140 GB compressed) plus a full database with an intranet injection endpoint, REST API source code, and billing photos — totaling 500 GB+ of allegedly fresh 2025 data. This revelation, found during routine dark-web monitoring, raises immediate risks for customers, partners, and the logistics sector at large. Read on for a detailed, actionable breakdown — with proof placeholders, mitigation checklist, and expert resources. 😱🔐📦
📸 [Forum post proof]
Quick summary: what the post claims
The threat actor’s message says: over 400 GB uncompressed, ~140 GB compressed (zst and other formats), database access (with an endpoint enabling code injection on the intranet), a “guide query API” exposing billing photos and customer information, and the REST API source code. They advertise “All fresh data 2025 include guides — total size = 500 GB+.” If authentic, this is both a massive data breach logistics firm event and an API/source-code theft nightmare. 🔥

How the leak was discovered
The Kaduu monitoring team (and other dark-web surveillance services) detected the listing during routine scans of underground forums and marketplaces. Cyber threat intelligence platforms such as DarknetSearch often uncover such postings hours to days before mainstream outlets — which is why continuous exposure scanning matters.

7 urgent facts about the Colvanes SAS data leak (concise list)
1️⃣ Scale: The actor claims 500 GB+ of data, including compressed/uncompressed dumps and images — this quantity is consistent with a mid-to-large logistics company’s transactional and multimedia data stores.
2️⃣ Type of data: Claimed contents include customer names, addresses, billing photos, shipment records, and API/source code — meaning both PII and system-level assets are at risk.
3️⃣ Attack surface: The post mentions an endpoint for code injection, indicating potential API or intranet misconfiguration.
4️⃣ Freshness: The seller claims these are “fresh data 2025” — modern/active records, not just old backups.
5️⃣ Sale format: Files offered in zst and other compressed formats, plus an interactive query API to browse data (very dangerous).
6️⃣ Trust & verification: At present the leak is reported by dark-web monitoring and early reporting sites — independent verification (file hashes, samples vetted by multiple firms) is limited. Treat as credible but unverified.
7️⃣ Industry impact: Logistics firms are prime targets due to the value of shipping records and business-continuity impact — expect regulatory interest and supplier alerts. 📛
Why this matters (risks explained)
The Colvanes SAS data leak and the linked Envía data leak go beyond simple file theft: they claim system access and exploitable endpoints. That elevates the threat from identity theft and phishing to active system tampering, fraudulent shipments, and potential supply-chain compromises. Exposed source code and APIs enable attackers to search for vulnerabilities, replicate internal logic, or craft sophisticated impersonation attacks. LSI phrases: database injection endpoint, billing photos leak, REST API source code exposed, data breach logistics firm, dark web data sale. 🔓🚨
Credibility check — evidence & red flags
Evidence supporting credibility: detailed file-size claims, mention of specific artifacts (billing photos, REST API), and detection by professional monitoring services. Red flags: no official Colvanes/Envía admission yet, and threat-actor or hackers screenshots can be faked. Until forensic verification (hashes, sample review by third-party responders) is public, treat the listing as likely but not fully proven. Proactive defensive steps are still recommended. ✅
Practical checklist — what to do now (for users & organizations)
For individual customers:
🛡️ Change passwords and enable MFA on associated accounts.
🛡️ Watch for phishing/impersonation messages claiming to be shipping notices or billing disputes.
🛡️ Monitor financial statements and credit reports for anomalies.
For corporate partners & vendors:
📋 Audit any integrations with Envía/Colvanes (APIs, SFTP, shared credentials).
📋 Block or rotate shared API keys and enforce least privilege.
📋 Scan logs for unusual API queries or large data exports starting weeks before 31 Oct 2025.
📋 Notify legal & compliance teams and prepare regulator notifications if affected.
For Envía / Colvanes themselves:
🔧 Engage independent forensic investigators and preserve logs.
🔧 Publish a factual, timely disclosure to affected parties.
🔧 Patch injection points, rotate credentials, and sandbox exposed APIs.
🔧 Increase dark-web monitoring and negotiate takedowns where possible.
Practical tip — quick verification steps for security teams
✅ Request file samples or hashes from monitoring providers and compare to backups.
✅ Check network egress logs for unusual large transfers.
✅ Isolate any public API endpoints and perform controlled scans.
✅ Consider legal takedown requests and notify data-protection authorities. 📌
Expert note & context
“Logistics and courier firms sit on rich PII and multimedia (billing photos) that attackers monetize quickly,” says a threat-intelligence summary on dark-web monitoring best practices by Recorded Future. ⚙️

Final analysis
The Colvanes SAS data leak (operating as Envía) may represent a major exposure of customer and operational data — including Envía customer billing photos leaked and API/source-code artifacts — that threatens privacy and system integrity. Even if some details remain unverified, the combination of claimed database access and source-code exposure warrants immediate action from customers, partners, and the company itself. Act now: rotate credentials, enable MFA, audit integrations and engage forensic help. 🔐🚀
