Cyber Crime Charges We Defend

We handle cyber crime cases across the full range of charged conduct that comes before the San Bernardino County Superior Court, Rancho Cucamonga District. California’s definition of “computer” under Penal Code 502 covers virtually any device that stores or transmits digital data, including smartphones, tablets, point-of-sale terminals, and IoT devices. That broad reach means more conduct qualifies as a cyber crime than most people expect.

Common charges we defend include:

• Unauthorized computer access under California Penal Code 502
• Identity theft under PC 530.5
• Internet fraud and phishing schemes
• Hacking and intrusion into private networks
• Cyberstalking
• Data theft and unauthorized use of stored information
• Online distribution of child pornography
• Cyber fraud schemes involving financial accounts or wire transfers

Cyber crime allegations frequently overlap with related offenses such as wire fraud, mail fraud, and money laundering, which means a single incident can produce multiple charges. Conduct that starts as a state matter can also escalate to federal jurisdiction when it crosses state lines, involves federal computer systems, or triggers losses above federal prosecution thresholds.

California Penal Code 502 & Federal Computer Crime Penalties

California Penal Code Section 502, the Comprehensive Computer Data Access and Fraud Act, is the primary state statute governing unauthorized computer access. It criminalizes accessing, damaging, deleting, or using data from a computer system without permission, and requires prosecutors to prove the defendant acted knowingly. That intent requirement is one of the most important contested elements in any PC 502 case.

Many violations are wobblers, meaning a prosecutor can charge the offense as a misdemeanor or a felony depending on the facts. Where a case falls on that spectrum has enormous consequences for what comes next.

Misdemeanor PC 502

A first-time violation that causes no injury to a computer system is generally punishable as a misdemeanor: up to one year in county jail and fines up to $5,000.

Wobbler to Felony

A case can escalate when the violation caused injury to a computer system or network, victim expenditures exceeded $5,000, the value of unauthorized computer services exceeded $950, or the defendant has a prior PC 502 conviction. When charged as a felony, penalties include 16 months, 2 years, or 3 years in state prison and fines up to $10,000. Courts may also order forfeiture of computers, software, and stored data under PC 502.01.

Federal Exposure

The same conduct can trigger parallel charges under the Computer Fraud and Abuse Act (CFAA), a federal statute covering unauthorized access to protected computer systems. Federal penalties vary significantly by offense type and circumstance but can reach up to 10 years in federal prison for serious violations. State cases are prosecuted by the San Bernardino County District Attorney. Federal computer crimes fall to the United States Attorney.

Consequences Beyond the Courtroom

The statutory penalties are only part of what a cyber crime conviction costs. A felony PC 502 conviction strips gun rights under California law. It also surfaces in employment background checks, affects professional licensing, can jeopardize security clearances, and may complicate housing applications and financial accounts.

Immigration consequences depend heavily on individual circumstances. Most PC 502 convictions don’t carry automatic adverse immigration effects, but non-citizens facing these charges should discuss their specific situation with an attorney before any plea is entered. Expungement may be available after a sentence is served, though eligibility depends on the facts of the case. Digital evidence tied to a criminal prosecution can also surface in civil lawsuits brought by alleged victims, meaning the criminal case and its collateral exposure don’t always end at the same time.

Defense Strategies in Cyber Crime Cases

Because PC 502 requires knowing conduct, one of the most effective defenses challenges whether the defendant understood they lacked authorization. Ambiguous workplace policies, shared system access, or unclear network permissions can all raise genuine doubt about intent. Kirk Tarman investigates the facts thoroughly before settling on a defense approach, because the strategy that works in one case won’t fit another.

Digital evidence also has technical vulnerabilities that experienced defense counsel can challenge. Shared IP addresses, dynamic IP assignment, shared devices, and network logs that point to a location rather than a specific person are all contestable. Chain-of-custody problems in how evidence was collected, preserved, or analyzed can support a motion to suppress. In cases involving workplace systems, access taken within the reasonable scope of job duties may serve as a defense under PC 502 itself.

Timing matters. Early intervention before the San Bernardino County District Attorney’s office formally files charges can affect how the case is assessed, including whether it proceeds as a misdemeanor or a felony.
