Method

OSINT

Collection and analysis of open or lawfully accessible information to answer a defined question.

Caution: Technical accessibility alone does not make every collection lawful or proportionate.

Method

Scope

Périmètre

The people, entities, periods, countries, sources and questions covered by research.

Caution: Overly broad scope increases noise, unnecessary data and error risk.

Method

Pivot

An identifier used to move from a verified item to another source, such as a domain, alias or official number.

Caution: A shared pivot does not prove that two items belong to the same person.

Method

Corroboration

Recoupement

Confirmation of a fact through genuinely independent, dated evidence suited to the question.

Caution: Multiple repetitions of one claim still represent one original source.

Sources

Primary source

Source primaire

Material produced directly by the actor, system or institution connected with the fact under review.

Caution: It strongly establishes the statement or record, not necessarily its complete truth.

Sources

Secondary source

Source secondaire

Analysis, synthesis or reporting based on primary sources or other publications.

Caution: Return to cited references before relying on a material claim.

Sources

Source independence

Indépendance de source

The degree to which an item relies on collection, testimony or method separate from other sources.

Caution: Different publishers may depend on the same wire report or press release.

Sources

Provenance

Documented origin of an item and the chain showing how it was obtained or transformed.

Caution: Incomplete provenance limits claims that can be made about authenticity.

Identity

Attribution

Reasoned connection between an action, content or asset and a person, entity or group.

Caution: A technical or stylistic coincidence is generally insufficient.

Identity

Namesake

Homonyme

A person or entity sharing an identical or similar name with the subject under review.

Caution: Always confirm several identifiers before attributing information.

Identity

Alias

A trading name, pseudonym or alternative identifier associated with a person or entity.

Caution: The same alias is often used by more than one person.

Identity

Digital impersonation

Usurpation numérique

Deceptive use of another party’s identity, image or distinctive signs on a digital service.

Caution: Separate public copying, a fake profile and compromise of the legitimate account.

Infrastructure

Domain name

Nom de domaine

Human-readable identifier associated with internet services and organised into dot-separated labels.

Caution: In a URL, identify the registered domain before interpreting subdomains.

Infrastructure

Subdomain

Sous-domaine

A label before the registered domain, used to organise services or create a misleading appearance.

Caution: A brand name in a subdomain does not mean that brand controls the site.

Infrastructure

Typosquatting

Registration of a domain resembling a known name through a typo, addition or character substitution.

Caution: Similarity is a signal requiring context, not automatic proof of fraud.

Infrastructure

TLS certificate

Certificat TLS

A certificate used to establish an encrypted connection and identify the covered domain.

Caution: It guarantees neither site honesty nor the claimed business identity.

Evidence

Digital evidence item

Élément de preuve numérique

A file, message, log, page or trace capable of supporting a fact when preserved with context.

Caution: Its value depends on origin, integrity and the question being asked.

Evidence

File hash

Empreinte de fichier

A value calculated from a file to detect later changes to its content.

Caution: A hash proves neither author, original date nor truth of the file.

Evidence

Metadata

Métadonnées

Information describing a file or content, such as format, dates, device, declared author or processing.

Caution: Metadata can be absent, altered, removed or created by software.

Evidence

Chain of custody

Traçabilité de conservation

Record of people, copies, transfers and transformations applied to a preserved item.

Caution: Legal requirements vary; obtain suitable advice where proceedings are contemplated.

Risk

Digital exposure

Exposition numérique

Observable assets, information and people that may be used to understand or target an organisation.

Caution: Visible information is not automatically an exploitable vulnerability.

Risk

Weak signal

Signal faible

An incomplete or isolated item that warrants checking but does not yet support a conclusion.

Caution: Accumulating dependent signals does not replace independent confirmation.

Risk

Confidence level

Niveau de confiance

Reasoned assessment of how strongly a conclusion is supported given sources and unknowns.

Caution: It is not a universal percentage of truth.

Risk

Risk scenario

Scénario de risque

A plausible chain connecting a signal, adverse action, affected asset and consequence.

Caution: A scenario supports prioritisation but does not automatically predict an event.

Influence

Narrative

Narratif

An interpretive frame connecting facts, symbols and claims into a coherent reading of a situation.

Caution: Repetition of a narrative proves neither coordination nor truth.

Influence

Amplification

Increased content visibility through reposting, recommendation, advertising or coordinated or spontaneous activity.

Caution: High visibility does not necessarily mean broad agreement.

Influence

Coordination

Common organisation of actions, messages or timing among several actors or accounts.

Caution: Timing and similarity alone may have other explanations.

Influence

Source laundering

Blanchiment de source

Movement of a claim through several relays until its weak or interested origin becomes obscured.

Caution: Return to the earliest observable version and identify dependencies.

Response

Containment

Confinement

Immediate measures limiting access, spread or impact before complete remediation.

Caution: Preserve useful evidence before irreversible deletion where appropriate.

Response

Remediation

Remédiation

Correction of the cause and conditions that enabled an incident or exposure.

Caution: Visible removal does not prove the cause, copies or access have disappeared.

Response

Escalation

Escalade

Structured transfer of a case to the level, team or authority able to act.

Caution: State facts, urgency, impact, completed actions and required decision.

Response

Lessons learned

Retour d’expérience

Post-action review that preserves learning, improves controls and clarifies responsibilities.

Caution: Assess the process without turning the exercise into individual blame.

Method

Hypothesis test

Test d’hypothèse

Comparison of an explanation against expected facts and competing explanations.

Caution: A plausible hypothesis is not a confirmed conclusion.

Sources

Source scope

Périmètre d’une source

The population, period, method and limits actually covered by a publication or dataset.

Caution: A reliable source may be unsuitable for a question outside its scope.

Identity

Entity resolution

Résolution d’entité

Careful matching of names, identifiers and attributes to determine whether they refer to the same person or organisation.

Caution: A common name or shared address is insufficient for identity attribution.

Infrastructure

Passive DNS

DNS passif

Observed history of relationships between domain names and DNS responses without actively probing target systems.

Caution: An old resolution or shared address does not prove current ownership.

Evidence

Capture context

Contexte de capture

Information accompanying a copy: full URL, date, time zone, apparent author and observation method.

Caution: A capture alone proves neither authenticity nor origin.

Risk

Exposure window

Fenêtre d’exposition

Period during which an asset or information may have been accessible under stated conditions.

Caution: Discovery time does not necessarily establish when exposure began.

Influence

Narrative relay

Relais narratif

Account, outlet or channel that carries a narrative to a new audience.

Caution: Repetition proves neither coordination nor endorsement by the relay.

Response

Asset owner

Responsable d’actif

Person or team responsible for validating, maintaining and arranging correction of an identified digital asset.

Caution: A name in an inventory must be confirmed before assigning responsibility.

Method

Competing hypothesis

Hypothèse concurrente

A plausible alternative explanation tested against the same observations as the main account.

Caution: Naming an alternative does not make it equally likely; it helps identify a discriminating observation.

Method

Stopping rule

Règle de clôture

A pre-defined criterion for ending research when the decision has enough support.

Caution: Ending a review does not remove uncertainty; remaining gaps belong in the report.

Sources

Source lineage

Chaîne de reprise

The sequence of publications copying or citing one initial item.

Caution: Several reposts of one origin are not independent confirmations.

Sources

Publication lag

Délai de publication

Time between an event or update and its appearance in a searchable source.

Caution: Absence from a recent database may reflect an update delay.

Identity

Recovery channel

Canal de récupération

An address, number or device used to regain control of an account.

Caution: An unapproved change can preserve third-party access after a password reset.

Identity

Delegated access

Accès délégué

Permission granted to another account to view or act within a service.

Caution: Changing a password does not always remove existing delegations.

Infrastructure

Registrable domain

Domaine enregistrable

The portion of an address representing the controlled name under a public suffix.

Caution: A subdomain or path can display a brand without that brand controlling the domain.

Infrastructure

DNS time to live

Durée de vie DNS

The advertised period for which a DNS answer may be cached.

Caution: It does not date domain creation or the actual start of a configuration.

Evidence

Original file

Fichier original

Version received or captured before annotation, conversion, cropping or redaction.

Caution: What counts as original depends on collection; a download may already be transformed.

Evidence

Time zone

Fuseau horaire

Reference needed to interpret local time and compare it with other timestamps.

Caution: A timeline without zones can put events in the wrong order.

Risk

Residual risk

Risque résiduel

Risk remaining after chosen measures have been applied.

Caution: A technical fix may reduce one avenue of harm without eliminating others.

Risk

Reversibility

Réversibilité

Ability to undo an action or decision if an assumption proves wrong.

Caution: A public removal or payment may be hard to reverse; the check depth should reflect that.

Influence

Sponsored content

Contenu sponsorisé

A post whose distribution is purchased or amplified by an advertiser.

Caution: Paid distribution does not confirm advertiser identity or message accuracy.

Influence

Earliest trace found

Première trace retrouvée

Oldest occurrence identified within a bounded search.

Caution: It may not be the original publication when archives or platforms are incomplete.

Response

Independent callback

Rappel indépendant

Confirmation obtained using a number known before the request or found separately.

Caution: Calling a number supplied in the suspicious message is not an independent check.

Response

Dual control

Double contrôle

Approval of a sensitive action by someone separate from the person preparing it.

Caution: Two clicks by one person do not create genuine separation of duties.

Identity

LEI

International identifier assigned to a legal entity in the Global LEI System.

Caution: Check status and renewal date; an identifier does not validate a transaction.

Risk

CVSS

Metric framework describing technical vulnerability severity through a score and vector.

Caution: Retain version and vector; severity alone does not measure business risk.

Risk

EPSS

Estimate of the probability of real-world exploitation of a CVE over the next thirty days.

Caution: The percentile is a rank; it is not the exploitation probability.

Response

KEV

CISA catalog of vulnerabilities known to be exploited in the wild.

Caution: Absence from the catalog does not mean absence of exploitation.

Risk

Sanctions match

Correspondance de sanctions

Potential match between a searched identity and a sanctions-list record.

Caution: Compare multiple identifiers and applicable legal text; a similar name is insufficient.

Method

Source dependency

Dépendance des sources

Relationship in which several publications rely on the same information origin.

Caution: Copies of one document do not add independent confirmation.

Editorial method

Terms are defined by what they allow you to establish.

Definitions favour operational clarity over jargon. They are written for case notes, decision briefs and communication between research, cyber, legal and management teams.

The caution attached to each term records its usual analytical limit. It prevents a technical label, source category or confidence expression from becoming a conclusion by itself.

FAQ

Using and reusing the glossary.

Does this glossary provide legal definitions?

No. It is an editorial and operational reference. Legal, regulatory and technical standards may define terms differently for a specific context.

Why does each term include a caution?

Because the most common analytical error is not ignorance of a word, but using it to claim more than the underlying evidence supports.

Can the dataset be reused?

The JSON and CSV files may be reused with attribution, while preserving the definitions, cautions and 2026 version date.

Provenance, version and reuse
