MLB says 'bad actors' played hand in data breaches on MLB Ballpark App

MILWAUKEE (CBS 58) — As tickets for the Milwaukee Brewers' 2025 postseason go on sale on Sept. 23, fans may want to change their MLB Ballpark passwords ahead of buying.

The MLB acknowledges in a statement that there has been "widespread reports of significant data breaches" from "bad actors." The breaches appear to be from stolen or leaked login credentials from other websites, then used to access the Ballpark App. MLB went on to say that "there is no evidence that this was a breach of the MLB system."

Cybersecurity expert Kern Smith, the Vice President of Global Solutions Engineering at Zimperium, said this is the latest in a trend that's targeting users. "This shows the breadth of these attacks. it’s no longer against the banking account, it’s everything that we encounter in our digital life."

It's recommended that fans reset their passwords to a new and unique password that isn't being used anywhere else, as a way to protect tickets and your account. It's unclear at this time how many people were impacted, though the timing of it is believed to be around Labor Day.

"What we’ve seen in our data is that attackers are becoming increasingly sophisticated in attacking mobile devices to screen capture or hook keyboards or observe users as they enter in their passwords into different applications at no fault of application owners," said Smith.

Fans like Leticia Vallarta say they miss the old-fashioned physical tickets that would've prevented this from happening in the first place. "
If you’re at the age where you don't want to have 10 million passwords, this is the reason why. it’s really only for your protection," she said.

Individual tickets for the first round of the 2025 postseason at American Family Field went on sale on Tuesday, Sept. 23, at 10 a.m. Fans like Bob and Vicky Rajenka made their way to the team store to get some merchandise that said "Division Champs". Bob said, "this is fantastic. I was down in downtown Milwaukee for the '82 pennant race when they won it. that was phenomenal. I’m hoping to repeat that again this year. everything is happening for a reason, that’s Uecker." His wife Vicky added, "they’re awesome, they’re playing awesome, you can’t say anything bad about them."

The Brewers are making their seventh postseason appearance in the past eight years and 11th overall in franchise history. Game dates and opponents will be finalized once the regular season standings and seeding are set.
