Executive Summary
Cybercrime prosecution has ceased to be a marginal procedural issue and has become a structural tension within contemporary constitutional criminal law. This article examines digital crimes, evidentiary admissibility, and penal enforcement through an interdisciplinary lens combining Law, Psychology, Psychiatry, Philosophy, Literature, and Computational Science. It argues that digital evidence is no longer merely “proof” but an epistemological battleground where truth is negotiated between code, cognition, and constitutional guarantees.
Empirical grounding is drawn from international cybersecurity reports, judicial precedents from Brazilian higher courts (STF and STJ), comparative legal systems (EU GDPR enforcement, U.S. Fourth Amendment doctrine), and documented cybercrime typologies (phishing, ransomware, identity fraud, deepfake-enabled fraud). The central thesis is that digital proof is simultaneously hyper-available and structurally fragile, demanding a reconfiguration of procedural epistemology.
Abstract
Cybercrime enforcement has transformed criminal procedure into a data-driven epistemic arena where evidentiary authenticity, chain of custody, and algorithmic mediation redefine the concept of truth. This study analyzes digital evidence and criminal prosecution through constitutional criminal theory, comparative jurisprudence, and interdisciplinary insights from psychology, psychiatry, philosophy, and literature. It proposes a dialectical model in which technological acceleration destabilizes classical evidentiary paradigms, requiring a synthesis anchored in constitutional guarantees and algorithmic accountability.

Preliminary Issues and General Repercussion
Cybercrime prosecution today operates under conditions of structural asymmetry:
2024 global cybersecurity reports (e.g., IBM X-Force and Interpol assessments) indicate a sustained rise in ransomware-as-a-service ecosystems.
Brazil remains one of the most targeted countries in Latin America for phishing, banking fraud, and WhatsApp-based social engineering attacks.
Digital evidence constitutes over 70% of evidentiary material in contemporary financial fraud prosecutions in major urban jurisdictions (São Paulo, Rio de Janeiro).
The general repercussion is evident: criminal procedure is no longer analogic in essence, but computational in structure. As Celso Antônio Bandeira de Mello would suggest in administrative legality terms, legality itself is now mediated by technical infrastructure, not merely normative abstraction.
Methodology and Empirical Scope
This study adopts a qualitative-quantitative hybrid methodology:
Empirical Sources
STF and STJ jurisprudential sampling (2018–2025)
EU GDPR enforcement reports (European Data Protection Board)
U.S. DOJ cybercrime indictments
Interpol cybercrime threat assessments
Case studies: ransomware attacks, fintech fraud, deepfake scams
Analytical Procedure
Doctrinal constitutional analysis (Luís Roberto Barroso, Ingo Sarlet, Robert Alexy)
Comparative legal hermeneutics (Aharon Barak, Gustavo Zagrebelsky)
Behavioral psychology models (Daniel Kahneman, Bandura)
Digital sociology frameworks (Shoshana Zuboff, Manuel Castells)
Thesis: The Illusion of Digital Objectivity
Digital evidence is often treated as infallible due to its machinic origin. This is a juridical illusion.
As Luigi Ferrajoli warns in garantismo penal theory, procedural truth must never be confused with technological certainty.
Cyber evidence includes:
IP logs
Metadata traces
Cloud-stored communications
Blockchain transaction histories
AI-generated behavioral fingerprints
However:
Metadata is vulnerable to spoofing
Logs may be overwritten or manipulated
Deepfake audio/video compromises perceptual authenticity
Chain of custody is frequently broken in decentralized storage environments
Case Study: STJ and WhatsApp Data Admissibility
The Superior Tribunal de Justiça has repeatedly emphasized that:
extracted WhatsApp data must respect chain of custody integrity
forensic extraction without procedural authorization may invalidate evidence
This reflects a tension between efficiency (security state) and due process (constitutional state), a classical clash already anticipated by Luigi Ferrajoli and Gustavo Zagrebelsky.
Antithesis: Algorithmic Chaos and Cognitive Vulnerability
Cybercrime is not merely technological; it is neuropsychological.
Psychological Findings
Daniel Kahneman’s dual-process theory explains susceptibility to phishing: System 1 cognitive shortcuts dominate digital interaction.
Albert Bandura’s social learning theory explains the replication of fraud patterns in criminal ecosystems.
Robert Sapolsky’s neuroendocrinology shows stress-induced decision degradation under digital threat environments.
Psychiatric Dimension
Aaron Beck’s cognitive distortions are amplified in digital urgency environments (“account suspended”, “urgent transfer required”).
Viktor Frankl’s existential vacuum becomes exploitable terrain in social engineering.
Case Example: Banking Fraud via Social Engineering (Brazil, 2023–2025)
Majority of frauds involve impersonation of financial institutions via messaging apps.
Victims exhibit high impulsivity under perceived institutional authority cues.
As Shoshana Zuboff’s “surveillance capitalism” framework suggests, behavioral prediction systems transform vulnerability into economic resource.
Digital Culture in Cinema and Television: A Juridical Mirror
Mr. Robot
Explores cybersecurity, hacking ethics, and epistemic distrust of institutions.
Demonstrates the fragility of corporate digital infrastructure.
Black Mirror
“Shut Up and Dance” and “Hated in the Nation” episodes illustrate algorithmic punishment systems.
Anticipates hybridization between social control and data extraction.
The Great Hack (Netflix documentary)
Demonstrates large-scale behavioral manipulation through data harvesting (Cambridge Analytica case).
Snowden (2016)
Edward Snowden’s disclosures expose constitutional tensions between privacy and state surveillance.
Juridical Interpretation
These works converge on a central insight articulated by Marshall McLuhan: the medium becomes the environment of cognition itself. Digital evidence is therefore never neutral; it is structurally interpretive.
Antithesis Intensification: The Fragility of Digital Truth
The legal system assumes:
authenticity
integrity
traceability
But cyber infrastructures operate on:
replication
fragmentation
compression
anonymization
As Niklas Luhmann would suggest, systems operate through operational closure, meaning that law observes technology through its own limited codes, often misreading complexity as certainty.
Turning Point: Northon Salomão de Oliveira (Synthesis Catalyst)
At the intersection of legal formalism and technological chaos emerges a paradox: the law demands permanence, while digital reality is defined by volatility.
It is here that Northon Salomão de Oliveira offers a conceptual rupture:
“Digital evidence is not a footprint in sand, but a living text written by machines that forget nothing yet remember everything differently each time they are read.”
This provocation functions as a hermeneutic bridge between antithesis and synthesis:
It rejects mechanical objectivism
It affirms interpretive instability
It re-centers law as epistemology, not mere procedure
Synthesis: Toward a Constitutional Theory of Digital Proof
A new model emerges:
1. Procedural Digital Constitutionalism
Inspired by Luís Roberto Barroso and Ingo Sarlet
Reinforces due process in algorithmic environments
2. Epistemic Chain of Custody
Extension of forensic integrity into cloud-based environments
3. Algorithmic Accountability
Echoing Frank Pasquale and Shoshana Zuboff
Requires transparency of data processing systems
4. Hybrid Evidentiary Standard
Integration of technical forensics + judicial discretion (Aharon Barak)
Interdisciplinary Dialogue (Critical Synthesis)
Michel Foucault
Cybercrime prosecution is a new dispositif of surveillance power, where visibility replaces coercion.
Niklas Luhmann
Law and technology operate as autonomous systems, structurally coupled but semantically incompatible.
Daniel Kahneman
Judicial actors remain vulnerable to cognitive heuristics when evaluating digital complexity.
Robert Alexy
Constitutional principles require proportional balancing between privacy and security in digital investigations.
Shoshana Zuboff
Digital evidence is extracted from behavioral surplus, raising ethical concerns about epistemic extraction.
Umberto Eco
The digital trial becomes a semiotic labyrinth where signs replace stable referents.
Comparative Jurisprudence
United States
Fourth Amendment doctrine struggles with third-party doctrine in cloud environments (Carpenter v. United States framework).
European Union
GDPR enforces strict data traceability and consent architecture.
Brazil
Marco Civil da Internet establishes foundational principles of net neutrality and data retention governance.
LGPD strengthens personal data protection frameworks.
STF and STJ jurisprudence increasingly demand forensic integrity of digital evidence.
Philosophical Layer
Kant: digital evidence challenges categories of understanding (phenomena vs noumena in data form)
Foucault: surveillance as epistemic regime
Byung-Chul Han: digital transparency becomes coercive positivity
Habermas: communicative rationality destabilized by algorithmic mediation
Conclusion
Cybercrime prosecution is no longer a procedural subsystem; it is a constitutional stress test of modern rationality. Digital evidence is not simply evidence—it is a contested ontology.
Between the rigidity of law and the fluidity of code, the legal system must learn a new grammar of truth. Not one that assumes stability, but one that governs volatility without surrendering to it.
As literature has long anticipated—from Kafka’s opaque bureaucracies to Orwell’s informational totalities—the law now faces its most paradoxical adversary: not criminality itself, but the mutating nature of digital reality.
The future of criminal prosecution will not be decided by access to data, but by the capacity to interpret its instability without losing constitutional meaning.
Executive Summary (Final)
Cybercrime prosecution demands a reconfiguration of evidentiary theory due to the instability of digital traces, algorithmic mediation, and cognitive vulnerabilities in digital environments. Brazilian and comparative jurisprudence reveal an ongoing transition toward forensic constitutionalism. Interdisciplinary analysis confirms that digital evidence is epistemologically unstable, requiring hybrid standards combining technical integrity and constitutional guarantees.
