Sale of 4 Million Stolen Cards Tied to Breaches at 4 Restaurant Chains

– THANKS TO BRIAN KREBS

“n Nov. 23, one of the cybercrime underground’s largest bazaars for buying and selling stolen payment card data announced the immediate availability of some four million freshly-hacked debit and credit cards. KrebsOnSecurity has learned this latest batch of cards was siphoned from four different compromised restaurant chains that are most prevalent across the midwest and eastern United States.”

I haven’t heard of anyone else reporting this, but just in case, here’s what happened:

I installed the   November Cumulative Update (KB4524570)  followed by Feature update to Windows 10, version 1909 shortly after 1909 was available (yeah, I’m a “bleeding edge” kind of guy!). Both were installed with no apparent issues.

It was only after I first tried to load TT 2019 that problems popped up. I would get the startup logo, but it would then disappear. The process would show up in Task Manager, but disappear in a second or two. After trying various suggestions via Intuit, I was ready to uninstall one or both of the updates.

One suggestion was to uninstall TT and reinstall it. When you start the uninstall, TT offers to “repair” the installation. Seemed like worth a try.

That was my fix. After the “repair”, TT loaded just fine. I’m posting this in case someone else runs into this “conflict”.
