MC2 Data base (Cybernews)THE HIDDEN COSTS OF FREE APPS: YOUR PERSONAL INFORMATIONWhat was the company doing with all that data anyway?As I mentioned, MC2 Data is a background check firm.

Remove your personal information from the internet: While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with the information they might find on the dark web, making it harder for them to target you. Check out my top picks for data removal services here.2. Be wary of mailbox communications: Bad actors may also try to scam you through snail mail. The data leak gives them access to your address. They may impersonate people or brands you know and use themes that require urgent attention, such as missed deliveries, account suspensions and security alerts.3. Be cautious of phishing attempts: Be vigilant about emails, phone calls or messages from unknown sources asking for personal information. Avoid clicking on suspicious links or providing sensitive details unless you can verify the legitimacy of the request. The best way to protect yourself from clicking malicious links that install malware is to have strong antivirus protection installed on all your devices. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.4. Monitor your accounts: Breaches of this magnitude will make it a necessity for you to start routinely reviewing your bank accounts, credit card statements and other financial accounts for any unauthorized activity. If you notice any suspicious transactions, report them immediately to your bank or credit card company.Kurt’s key takeawayWhen your business model relies on collecting people’s data and providing services based on that information, you must do everything possible to protect it. This is not only a moral responsibility, it’s also a legal requirement. MC2 Data has failed to meet this obligation, and its negligence puts millions of Americans at risk, many of whom were unaware their data was being collected by the firm. Companies should face strict legal actions and hefty penalties for such incidents rather than just receiving a slap on the wrist.CLICK HERE TO GET THE FOX NEWS APPWhat do you think should be the consequences for companies that fail to protect consumer data?
