Illegal Data Access
Criminal defense for unauthorized access to computer systems and interception of telecommunications (Art. 197 bis-ter CP).
Cybercrime in Spain: Hacking, Phishing & Digital Fraud — Defence Guide
Cybercrime encompasses illegal access to computer systems (Art. 197 bis CP), computer damage and ransomware (Art. 264 CP), phishing and digital fraud (Art. 249.1.a CP), and the production or distribution of hacking tools (Art. 197 ter). Spain's prosecution of cybercrime has intensified dramatically, with specialised units in the National Police (BIT) and Guardia Civil (GDT) leading investigations. Defence requires a unique combination of criminal law expertise and advanced technical knowledge.

Key Defence Strategies
IP Attribution Challenge
An IP address does not identify a person. Shared Wi-Fi networks, VPNs, Tor exit nodes and NAT configurations mean multiple users may share one IP. The prosecution must prove the accused was the actual user at the relevant time.
Chain of Digital Custody
Digital evidence is extremely fragile. If the police failed to image the hard drive with a write-blocker, if hash values don't match, or if evidence was handled improperly, the defence can seek exclusion of the entire digital evidence chain.
Authorised Security Testing
Ethical hacking and penetration testing carried out with the system owner's authorisation is legal. If the defendant had a written engagement contract, bug bounty agreement or responsible disclosure policy, there is no criminal offence.
Lack of 'Breaching Security Measures'
Art. 197 bis requires that security measures were breached. If the system had no password, no firewall, or the access point was public, the element of 'breaching security' may be absent, negating the offence.
Key Case Law
The Supreme Court confirmed that 'access' requires effectively entering the system, not merely attempting it. The prosecution must prove: (1) access occurred, (2) it was unauthorised, and (3) security measures were breached. Port scanning alone does not constitute the offence.
The Court ruled that ransomware attacks may constitute a concurrent offence of computer damage (Art. 264) and extortion (Art. 243 CP). The encryption of data satisfies the 'damage' element even if data is technically recoverable upon payment.
In phishing operations, the Court distinguished between the organiser and the 'money mule' (account holder). The mule's liability depends on proof of knowledge that the funds were illicit. Wilful blindness may suffice, but mere negligence does not.
