How Data Breaches Occur
Data breaches happen in various ways. Common methods include:
- Phishing Attacks: Deceptive emails which trick authorized users into providing sensitive information like passwords to criminals.
- Malware: Malicious software, such as viruses or ransomware, is used to infiltrate systems and steal or encrypt data.
- Weak Passwords: Using easily guessable or outdated passwords make it easy for hackers to gain access.
- Unpatched Vulnerabilities: Failing to update software can leave known security gaps that attackers can exploit.
- Insider Threats: Employees or contractors with access to sensitive data may compromise security.
- Social Engineering: Manipulating individuals into divulging confidential information.
- Data/Device Theft: Physical theft of devices, such as laptops or external drives, which grant access.
Why Companies Need to be Held Liable
Corporations will tell you they are the “victims” in data breaches. Not so. Those who suffer after a data breach are those who have lost their privacy, their money, their peace of mind. When inadequate cybersecurity measures have led to a data breach, the law says you can sue for money damages under many theories, such as:
- Negligence;
- Breach of Implied or Express Contract;
- Breach of the Implied Covenant of Good Faith and Fair Dealing;
- State law claims such as the California Confidentiality of Medical Information Act (Cal. Civ. Code §§ 56, et seq.), California Consumer Legal Remedies Act (Cal. Civ. Code §§ 1750, et seq.), California Information Practices Act of 1977 (Cal. Civ. Code §§ 1798, et seq.), California Consumer Records Act (Cal. Civ. Code §§ 1798.80, et seq.) and California’s Unfair Competition Law (Cal. Bus. & Prof. Code §§ 17200, et seq.)
- Fair Credit Reporting Act.
