Data leak check

Data leak check by 0trust0day is built for situations where an organization needs controlled technical action rather than generic advice. The usual context is leaked personal data, credentials, documents, source code, financial files or customer databases. We begin with a safe intake, confirm scope, define emergency contacts and explain which information can be shared. We do not request passwords, seed phrases, private keys or secret tokens. Instead, we work with ownership evidence, logs, screenshots, mail headers, technical artifacts and minimum approved access.

Teams often see isolated symptoms and miss the full attack chain. The affected assets often include domains, email, brands, executives, GitHub, paste sites, Telegram channels, breach datasets and dark web. One signal may look small: an unusual login, a customer report, a new administrator, a disabled plugin or a platform warning. For an attacker, the combination can become a path to data, money or reputation damage. Our job is to separate noise from critical facts and decide where immediate containment is required and where planned remediation is enough.

We review domain matches, reused passwords, dump publications, indexed documents, brand mentions and databases for sale, build a technical hypothesis and move iteratively through triage, containment, evidence, recovery and hardening. Each step is documented so the result is useful for leadership, engineering, legal and, when needed, insurers or platform support. Deliverables include leak report, risk priorities, proof snippets without unnecessary data spread and response plan. The output is not a generic scan; it is a prioritized action plan with evidence, ownership, next steps and retest criteria.

Example: a B2B platform before due diligence contacted 0trust0day after an old dump contained employee emails and passwords reused in SaaS. At first the client saw only an external symptom and did not know whether all operations had to stop. We agreed scope, collected evidence without secrets, rebuilt the timeline, identified critical systems and proposed containment that respected business continuity. Then we validated the likely re-entry path, closed the most urgent gaps and prepared a concise executive summary. Result: the company closed the risk before the deal: passwords rotated, MFA hardened and investors received a remediation report. This turns an incident from panic into a manageable security backlog.

Before the consultation, prepare a safe minimum set of context: approximate start time, affected systems, screenshots of warnings, platform emails, public links, support ticket IDs and a short description of actions already taken. Do not send passwords, seed phrases, private keys, one-time codes, MFA backup codes or full dumps of personal data. If the situation is urgent, start with business impact: what is stopped, which payments or accounts are at risk, whether the attacker contacted you and which deadlines they are imposing.

The price on this page is an estimate for small accounts and compact systems. Final cost may move down or up after consultation depending on urgency, number of systems, data sensitivity, night work, legal coordination, SLA and report depth. A 20% non-refundable prepayment is required to place the request. In the form, include your preferred consultation time, a plain-language description without passwords, affected accounts or systems, incident timing and, for scans, whether previous attacks happened and when you want the scan performed.
