Three major data breaches made headlines this spring. Charter Communications lost up to 42 million customer records. Carnival Cruise Lines had nearly 6 million customers’ personal data stolen. And 7-Eleven confirmed that 185,000 franchise applicants had their Social Security numbers, driver’s licenses, and contact details exposed.

If you are reading this and thinking “I don’t use Spectrum or book cruises,” keep reading. This still affects you. Here’s why.

What Actually Happened in Each Breach

Charter Communications (Spectrum)

In late May 2026, the hacking group ShinyHunters claimed to have stolen between 40 and 42 million records from Charter’s Salesforce instance. The attack started with a voice phishing call that tricked a Charter employee into handing over access to a Microsoft account. From there, attackers exported customer records containing names, addresses, email addresses, phone numbers, and nearly 10 million customer support ticket records. Charter confirmed the breach and said authorities have been notified.

Carnival Cruise Lines

In April 2026, attackers used social engineering to deceive a Carnival employee and gain access to internal systems. By the time the company confirmed the breach, 5,995,277 customers had been affected. The data taken includes names, addresses, email addresses, phone numbers, dates of birth, and government-issued ID numbers including driver’s license and passport numbers. Carnival started sending breach notification letters in late May, nearly six weeks after the incident was confirmed. They are offering 24 months of credit monitoring through TransUnion.

7-Eleven

ShinyHunters, the same group behind the Charter breach, hit 7-Eleven’s franchise application systems in April 2026. The breach exposed data on 185,000 current, former, and prospective franchise applicants, including Social Security numbers, driver’s licenses, names, dates of birth, addresses, and phone numbers. When 7-Eleven declined to pay the ransom, the group published a 9.4-gigabyte archive of the stolen files publicly. 7-Eleven stated that regular store customers were not affected, but the damage to individuals in that franchise database is already done.

This Is Not Unusual. This Is Tuesday.

These three breaches happened within weeks of each other. That is not a coincidence or a spike. That is the baseline. Researchers analyzed over 19 billion exposed passwords from breaches between April 2024 and April 2025 alone. Major breaches involving millions of records happen every month. The question is not whether your data has been exposed somewhere. It almost certainly has. The question is what an attacker does with it once they have it.

How an Attacker Actually Uses This Data

When your data shows up in a breach, it does not just sit there. Here is what happens next.

Step 1: The data gets cleaned and sold

Stolen records get combined with data from other breaches. Attackers match your name and email from the Charter breach with your date of birth from a previous breach and your phone number from another. This is called data aggregation. The result is a detailed profile on you that costs a few dollars to buy on a criminal marketplace.

Step 2: Credential stuffing begins

Attackers take email and password combinations from old breaches and run them through automated tools that try those credentials on thousands of websites simultaneously. This is called credential stuffing. It works because most people reuse passwords. If your email and password from a 2019 breach still opens your bank account, your streaming services, or your Amazon account, the attacker is in within seconds.

Step 3: Targeted phishing with your own information

Now the attacker knows your name, where you live, who your internet provider is, and that you recently took a cruise. They send you an email that says “Important notice regarding your Spectrum account” or “Your Carnival credit monitoring enrollment requires verification.” The email looks real because it contains real details about you. You click. You enter credentials. Now they have something fresh.

Step 4: Account takeover and lateral movement

Once inside one account, attackers look for connected accounts, saved payment methods, and password reset options. They change the recovery email. They pivot to your bank using the “forgot password” feature sent to the email account they just took over. This chain can go from a data breach to a drained bank account in under an hour when the conditions are right.

Step 5: Identity fraud using government ID data

For the people caught in the Carnival and 7-Eleven breaches, the threat goes further. Passport numbers, driver’s license numbers, and Social Security numbers can be used to open new credit accounts, file fraudulent tax returns, or apply for loans in your name. This damage can take years to fully undo.

The Password Reuse Problem Is the Real Multiplier

Here is the number that should concern every person reading this: 94% of passwords in breach databases are reused or duplicated across multiple accounts. Separately, 78% of people admit to using the same password for more than one account. Nearly 1 in 7 people use the exact same password for every account they have.

This is why a breach at Charter becomes a threat to your Gmail. This is why a breach at Carnival puts your PayPal account at risk. The breach does not have to be at your bank. The breach just has to surface a password you also use at your bank.

Password reuse turns every breach everywhere into a potential breach of everything you own online.

Why Resetting Your Password Is Not Enough

When a company notifies you of a breach, the standard advice is to change your password on that platform. That is the minimum. It is not enough.

Changing your Spectrum password does nothing if you used that same password on your bank, your email, and your health insurance portal. The attackers do not need your new Spectrum password. They already have the old one, and they are running it everywhere else right now.

A password reset at the breached company is like changing the lock on one door of your house after someone made copies of every key. The lock you changed is now fine. Everything else is still open.

What You Should Actually Do

None of this requires a technical background. It requires about an hour of focused time and a few habit changes.

1. Get a password manager and use it

Bitwarden is free and open source. 1Password and Dashlane are solid paid options. A password manager generates and stores a unique, complex password for every site you use. You only need to remember one master password. This single change eliminates credential stuffing as a threat to you because every account has a password that exists nowhere else.

2. Turn on multi-factor authentication on everything that matters

Email, banking, social media, cloud storage, and any account tied to money or personal data should have MFA enabled. An authenticator app like Google Authenticator or Authy is better than SMS text codes, but SMS is better than nothing. If an attacker gets your password, MFA stops them at the door.

3. Check whether your data has been exposed

Go to haveibeenpwned.com and enter your email address. It shows you every known breach your email has appeared in. If you show up in a breach, prioritize changing that password and any other account where you used the same one.

4. If your SSN or passport number was exposed, freeze your credit

A credit freeze is free at all three major bureaus (Equifax, Experian, TransUnion) and prevents new accounts from being opened in your name without your explicit authorization. If your information was in the Carnival or 7-Eleven breaches, do not wait for identity theft to happen. Freeze now and unfreeze when you need to apply for credit.

5. Be skeptical of any communication you did not initiate

In the weeks and months following a breach, targeted phishing attempts go up significantly. If you get an email, text, or phone call about your account from any company involved in a breach, do not click links and do not confirm personal information. Go directly to the company’s website by typing the address yourself and log in from there.

The Bottom Line

Breaches like Charter, Carnival, and 7-Eleven are not isolated events. They are part of a continuous stream of incidents that collectively expose billions of records every year. Your data has almost certainly appeared in at least one breach you never heard about.

The companies that got breached bear responsibility for protecting your data. But once that data is out, the only person who can limit the damage to your accounts and identity is you. The steps above are not complicated. They are just not optional anymore.

If you are a small business owner or manage a team, the same exposure that threatens individuals also threatens your organization. Employees who reuse passwords give attackers a path into your systems. If you want help evaluating your organization’s exposure or building basic controls, that is exactly what I do.
