Data leak at Startup Paay
Paay is a start-up company in the field of payment transactions. Now a huge database has appeared, in which credit card transactions from eight months are openly stored. The data also includes the complete credit card numbers in plain text. The security researcher Anurag Sen has found the open database on the Internet. It was probably created on April 3, 2020 for a new service, but forgot to protect the database. Techchrunch has written up the story in this article. In the following tweet, Zack Whittaker points out the statement of the company founder.
Paay's co-founder disputed the findings. "We don't store card numbers, as we have no use for them," he said. So we sent him a portion of the exposed data showing card numbers in plaintext. We didn't hear back. (We blanked out the full numbers below.) https://t.co/rKPx3G1BCP pic.twitter.com/txqctqI1M5

He denies that there are credit card numbers in the database because you don't need them. Techchrunch sent him a record with that exact same information and he didn't hear anything.

Revive AD Server hacked
Most online publishers use hosted ad server platforms like Google Ad Manager to serve their ads (this is the case in my blogs). Some publishers use self-hosted ad serving platforms to give them more control and flexibility in delivering their ads. One self-hosted open source platform that has been around for the past ten years is the Revive Ad Server.

It has now been revealed that the malvertising group Tag Barnakle is hacking into Revive's ad servers to deliver malicious advertising. The security company Confiant claims that about 60 servers are affected. Bleeping Computer has made a contribution to this, which is linked to in the above tweet.
