Violation of national data protection: 2.9 billion people affected

It’s hard to imagine anything worse than a hacker attacking a background check company whose sole job is to dig up and collect non-public data. A lawsuit claims that National Public Data’s negligence exposed 2.9 billion people. The details include social security numbers, full names and addresses. The hacker group ASDoD has put the database containing the stolen information up for sale for $3.5 million. There’s no word yet of a ransom payment.

Through a process called scraping, NPD collects and stores personal information from “nonpublic sources” to conduct background checks. In other words, the company collects information that has not been voluntarily (or knowingly) shared.

Depending on what happens in court, the NPD could be required to delete the personal data of the persons concerned and to encrypt all data collected in the future.

Ascension ransomware attack: Up to 140 hospitals

In May, an employee at one of the country’s largest healthcare systems accidentally downloaded malware, sparking an avalanche of cyberattacks.

Ascension operates 140 hospitals in 19 states and Washington, D.C. On May 8, they discovered unusual activity on their network. The outage quickly became so bad that Ascension had to close emergency rooms and divert patients.

Hackers have gotten their hands on 7 of Ascension’s 25,000 servers. Who was affected is still under investigation. Ascension recently stated that about 500 people were affected, but I’m willing to bet the final number will be much higher.

Global CDK attack: 15,000 car dealerships

One of the largest auto dealership software companies was hit twice in June. CDK, used by 15,000 auto dealerships for payroll and finance tasks, had its systems brought down after two consecutive cyberattacks on June 18 and 19. The ransom payment was rumored to be in the tens of thousands of dollars. Million of dollars.

How to get cheap stuff (to keep or resell)

Double-check all healthcare communications. If you receive an Explanation of Benefits (EOB) or a bill for services you did not receive, contact your doctor and insurance company immediately. This likely means someone is using your services for their own health care.

Be careful with email inquiries. Be skeptical of anything that seems super urgent. It’s OK to slow down for safety’s sake. My rule of thumb: If it’s a weird written request, like a text or email, I’ll call.

Be wary of “old friends” who appear out of nowhere. It could be a hacker who happens to have some (stolen) information. Take the time to confirm that this is indeed the culprit.

Create a list of disclosed data. Keep this information digitally or on a post-it. Be suspicious if someone refers to it in an email or phone call. Let’s say the company you used to finance your car was hacked. If you get a call out of the blue saying there’s a big problem with your credit, alarm bells should be ringing.

Update your PIN and banking credentials. Even if they weren’t directly involved in the data theft, hackers can still use your personal information to access it. Pay attention to your bank and credit card statements for anything unusual. Also, set up banking alerts on your phone.

Freeze your credit. Here’s how to prevent scammers from opening a credit card or loan in your name. As with setting up a fraud alert, you’ll need to contact each of the three credit bureaus.
