Cyber-security data breaches are an invasion of an employee’s privacy. At HKM Employment Attorneys, we are committed to helping victims of employment-related data breaches in Riverside, California. Our attorneys have extensive experience filing class-action lawsuits for employees who have been the victims of data breaches.

Employers Must Use Reasonable Care to Keep Employee Data Safe

Employers have a duty to maintain reasonable and adequate security measures to protect the personal identifying information (PII) of their employees. When employers breach this duty of care by acting negligently or recklessly, they put their employees at risk of becoming the victims of cyber criminals. These types of cyber attacks are on the rise, and employers could be expensing their employees to tax fraud, medical fraud, credit card fraud, and phishing scams.

How Do Cybercriminals Target Employees?

Cybercriminals are constantly targeting employee data stored by employers. They specifically target information with sensitive health and financial information. Cybercriminals will often hack into company e-mails. They may impersonate executives within the company by sending out “phishing” emails to company employees. Scammers may request access to sensitive and confidential information or seek to transfer large sums of money from the company. These types of scams are usually called Business E-mail Compromise Scams (BEC).

Unfortunately, phishing scams can cause massive losses of sensitive information that can cause significant future damage to the company’s employees. Consequently, law enforcement and cyber-security professionals consistently warn corporations about similar types of cyber threats and provide guidelines for best practices and training for preventing, detecting, and handling cyber-attacks.

Many Cyber Criminals Pursue W-2 Data

W-2 data and employee PII are highly pursued by cyber criminals as collected information allows for not only identity theft and future financial wrongs but fraudulent tax filings through the victim’s name. When cybercriminals obtain an employee’s confidential information, it is commonly sold on the black market, specifically on torrent networks. This information is often used to commit financial fraud within hours of cyber criminals obtaining the information.

Many Data Breaches are Caused By Insider Threats

Many employees know the ins and outs of their employer’s infrastructure and cybersecurity tools. Every month there are hundreds of malicious and inadvertent insider security threats every month. With insider threats, an employee of the company either knowingly or accidentally shares employment information with cybercriminals. Doing so can cause data breaches that harm companies and their employees.

Insider attacks are most likely caused by negligent or inadvertent users, criminal or malicious insiders, or attackers that stole user credentials. Insider attacks are dangerous because insiders do not act maliciously most of the time. This can make it harder to detect harmful insider activities than it is to detect attacks from outsiders. Insiders know the company’s weaknesses in terms of organizational cybersecurity. Insiders also know the nature and location of sensitive data they can exploit.

Data Breaches Can Harm Employees for Years to Come

When an employer’s systems are exposed through a data breach, employees can suffer damage for years after the initial breach. The Federal Bureau of Investigation (FBI) provides notifications and updates on cyber-security threats, including warnings about these exact types of threats. The U.S. government and several private security research firms widely distribute reports about all of the many new types of malicious cyber-security threats that place employers on notice that are at risk.

Proven Experience in Employment Data-Breach Cases

In March 2016, HKM Employment Attorneys filed a class action lawsuit against a pharmacy employer. We represented over 800 employees whose information was stolen due to their employer’s inadequate security measures.

In April 2016, HKM Employment Attorneys filed a class action lawsuit on behalf of more than 1,500 employees. In this case, a real estate investment employer failed to stop a cyber-attack that compromised employees’ data. We regularly review allegations of data breaches and actively investigate reports from employees in Riverside and throughout California.

Your Employer Should Have Known Better

While it can be easy to feel sorry for your employer’s losses, it is important you think of your own damages first and foremost. Your employer has received constant warnings from cybersecurity professionals and law enforcement about phishing scams and hacks. Your employer most likely had the opportunity to enhance their security system, prevention methods, and employee training.

When your employer was hacked, they failed to take reasonable steps to protect you and your personal information. Your employer has an obligation to protect your personal information from cyber-attacks. When they fail to do so, you have the right to hold them accountable by pursuing a legal claim against them.

What Employers Should Do to Protect Employees from Data Breaches in Riverside

Employers must implement cybersecurity measures in light of the size of their company and the nature of its work. Larger businesses and relatively small businesses that process a lot of payments should hire cybersecurity personnel on a full-time basis, even if it is on a consulting basis. Other steps businesses should take to protect their customers and employees include the following:

  • Install software updates on their electronic devices promptly
  • Have a cybersecurity team diagnose weaknesses in the system’s security regularly
  • Require strong passwords for employees’ email accounts and web portal access
  • Require two-factor identification for employees to access company devices and online accounts

If you realize your work has been the target of a data breach, it is essential to speak to an attorney as soon as possible. If you have suffered financial losses because of hackers breaching your employer’s computer network or stealing your personal information, you have the right to sue your employer for damages.

This is an impressive law firm. Nothing but praise. Although they could not take my case; about 30 minutes was spent on the phone with me, going over my case and options I had. Real heart ❤️👏

There are certain rooms you never want to walk into alone. A deposition. A courtroom. The silence that follows the words, "you've been terminated." If you told me that I would survive those two years and come out the other side stronger, I wouldn't have believed you for one second. I want to be honest: I hate legal stuff. I would rather lock myself in a room with an angry goose than deal with any of it. Litigation is exhausting, invasive, and there's nothing fun about it. I'm serious! And yet, somehow, Rebecca made it bearable. I don't say that lightly. What she did wasn't magic and it was harder than being smart (though she's that too). She's unshakably calm and relentlessly prepared. She showed up, over and over, in the moments when I was barely holding myself together. Not once did she make me feel like a case number or the puddle of a human being that I was at the time. She saw me, she heard me, and she had my back at every single turn, quietly and completely, the way people do when they actually mean it. I think that's the part that gets me the most, looking back. It wasn't just that she fought for me, it's that she made the worst chapter of my professional life into something I could get through. And then she helped me get through it, one step at a time, with the kind of patience and care that I didn't expect from someone whose job was to represent me. It's rare to meet someone whose words actually stay with you, long after the case is closed. Rebecca is one of those people. She isn't just an exceptional attorney, she's a genuinely wonderful person, the kind who makes you believe that good people still choose hard, thankless work because they care. So, if you ever find yourself in a room that feels scary (like with an angry goose), facing something too big to carry alone, Rebecca is exactly who you want standing beside you.

Rebecca is the kind of attorney you hope to find but rarely do. She provided legal services during a critical moment for me, and her impact went far beyond what I expected. She brought clarity to complex areas, asked thoughtful questions I hadn’t considered, and ultimately gave me the confidence to move forward. What truly sets Rebecca apart is how she shows up as a person. She leads with empathy, listens deeply, and genuinely cares about the people she works with. You never feel like just another client. You feel supported, understood, and in very capable hands. She has that rare combination of sharp legal expertise and a grounded, human approach that makes complex situations feel manageable. I trust her completely and would recommend her to anyone looking for not just a great attorney, but a true partner. If you have the opportunity to work with Rebecca, take it.

When facing a severance agreement that needed to be addressed immediately, HKM called me back quickly and provided excellent advice. Thanks to following their advice all of my concerns were addressed and my former company made adjustments to our agreement that helped my family immensely.

This was my first time engaging in any sort fo legal service agreement. Put simply -- Erin Norgaard, Brian Dolman and the HKM Team are heroes in my eyes. I was faced with a very stressful employment dispute that put my livelihood at stake. Erin was fast to respond to my inquiry, took my case, and then brought Brian on board as well. They had complimentary areas of expertise that felt custom fit to my case. They are seasoned lawyers, yet they were sensitive to my situation and were personal with me when corresponding. It was always educational listening to them think aloud as they would anticipate the actions of the other party. They are at the top of their field, they know it, and it showed in their bravery when communicating with the other party. I have absolute trust in them -- there was never a moment that I didn't feel the utmost confidence in their legal strategies. We reached a favorable outcome in the end and I'm eternally grateful for their hard work. If you have the opportunity, jump on the chance to work with them. I recommend their counsel very highly.

I could not have been happier with the advice and service I got from Cecilia Brennan at HKM that saved me from signing and accepting a one-sided severance package from my former employer. I would highly recommend this firm to anyone. I received prompt and professional service.
