Overview#
After a ransomware operator demands 47 Bitcoin from a hospital network, the incident response team faces two immediate questions: should they pay, and if they do, where does the money go? Tracing the ransom payment requires following funds through mixer services, cross-chain hops between different blockchains, and eventual cash-out at exchanges that may or may not cooperate with law enforcement. Getting that attribution right, quickly enough to support asset recovery, requires investigation workflows purpose-built for cryptocurrency crime. That is what Argus Cryptocurrency Investigations provides.
The platform delivers end-to-end investigation workflows and case management capabilities specifically designed for cryptocurrency-related crimes. It enables law enforcement agencies, regulatory bodies, financial crime investigators, and cybersecurity teams to investigate ransomware attacks, darknet market operations, ICO fraud, and other crypto-enabled crimes with tools for evidence collection, case collaboration, and legal disclosure management.
Open Standards#
- OASIS STIX 2.1 / TAXII 2.1: Threat intelligence exports for partner agencies are serialised as STIX 2.1 bundles and delivered over TAXII 2.1 feeds, enabling interoperability with Europol, Interpol-aligned networks, and financial intelligence units.
- W3C Verifiable Credentials Data Model v2.0: Chain-of-custody provenance for blockchain evidence items is cryptographically signed and issued as W3C VCs, providing tamper-evident, court-admissible attestations tied to each analyst action.
- RFC 3161 (Internet X.509 PKI Time-Stamp Protocol): Forensic evidence packages can be embedded with RFC 3161 trusted-timestamp tokens from a configured TSA, binding evidence exports to a verifiable point in time for legal proceedings.
- FIPS PUB 180-4 (SHA-256): Every forensic report is assigned a SHA-256 integrity hash at generation time; verification checks recompute the hash to detect any post-hoc tampering before the report is admitted as evidence.
- FATF Recommendations / EU Anti-Money Laundering Directives (AMLD): Sanctions screening logic and playbook red-flag indicators are aligned to FATF AML/CFT guidance and the EU 4th/5th AMLD thresholds, and screening results are logged to a compliance audit trail for regulatory purposes.
- Ethereum Token Standards (ERC-20, ERC-721, ERC-1155): Multi-chain fund-flow analysis natively tracks ERC-20 fungible transfers, ERC-721 NFT movements, and ERC-1155 multi-token events alongside native-coin transactions.
- GraphQL (June 2018 specification): All investigative data, wallet clusters, transaction graphs, case entities, and evidence records, is queried and mutated through a GraphQL API, enabling precise, type-safe data retrieval by investigative tools and third-party integrations.

Key Features#
Investigation Workflows#
Purpose-built workflows cover crypto crime investigations from initial lead through prosecution. Structured case progression includes evidence milestones, collaboration checkpoints, and prosecution readiness assessment. Multi-case investigation management supports parallel investigations with shared entity intelligence across 15+ blockchain networks.
Ransomware Investigation Toolkit#
Attribution analysis, fund tracing through ransom payment chains, negotiation tracking, and recovery workflows all map ransomware payment flows from victim wallets through mixing services to cash-out points. The toolkit tracks historical payment patterns for known ransomware groups to support rapid attribution when new incidents emerge.
Darknet Market Intelligence#
Vendor profiling, marketplace analysis, and cross-platform tracking enable investigators to monitor darknet market activity, identify vendors across platforms, and correlate marketplace identities with real-world identifiers. Integration with over 153 third-party data sources, including Shodan and Maltego, supports infrastructure attribution.
ICO and DeFi Fraud Detection#
Token contract analysis, rug pull detection, and investor protection investigation tools identify fraudulent token offerings, track misappropriated funds, and build cases for regulatory enforcement. Smart contract analysis surfaces deceptive mechanics embedded in token contracts before they are flagged by victims.
Multi-Agency Collaboration#
Secure case sharing with prosecutors, regulatory agencies, and international partners uses role-based access to ensure each collaborator sees appropriate information while maintaining investigation security. STIX/TAXII-format intelligence exports support sharing with Europol, Interpol-aligned networks, and partner financial intelligence units.
Court-Ready Evidence Packages#
Chain-of-custody preservation, cryptographic verification, and disclosure bundle generation package blockchain evidence, transaction analysis, and attribution findings into formats accepted by courts and regulatory bodies. Every analytical step is logged with timestamp and analyst identity for full evidential traceability.
Use Cases#
- Ransomware Response: Investigate ransomware incidents from initial attack through payment tracing, attribution, and fund recovery coordination with financial institutions and exchanges.
- Darknet Market Prosecution: Build cases against darknet market vendors through marketplace monitoring, cryptocurrency tracing, and identity correlation across platforms.
- Financial Fraud: Investigate ICO fraud, DeFi exploits, and cryptocurrency-enabled money laundering with blockchain analysis and fund flow documentation.
- International Coordination: Collaborate with international law enforcement partners on cross-border cryptocurrency crime through secure case sharing and evidence exchange.
Integration#
Connects with blockchain analysis platforms, exchange cooperation interfaces, case management systems, and evidence management platforms. Supports multi-chain analysis across 15+ networks and integration with financial intelligence tools. Compatible with STIX/TAXII sharing for Europol and Interpol-aligned network intelligence exchange.
