You may have seen some news circulating around tech websites today that gave you a scare. Headlines similar to "89 Million Steam user records leaked in massive data breach" started to pop up everywhere, often accompanied by warnings about how you should change your passwords right now!
First off, calm down. Secondly, it looks like there really isn't much to worry about at all.
Earlier today, someone going by the alias of Machine1337 claims to be in possession of over 89 million Steam user records. This person was offering to sell this data for a mere $5,000. The fact that the person was asking for just $5,000 on what would theoretically be a goldmine of data should have sent up immediate red flags that maybe the claims from the alleged leaker were complete fabrications.
Christopher Kunz, a security expert working for heise Security, took a look at the publicly shared data from this alleged Steam security breach. According to what Kunz saw, the bad threat actor isn't selling Steam user data, they're trying to sell "89 million SMS send log records."
This is just a "fart in a puddle" as a darknet user put it. Basically, what the threat actor obtained and now wants to sell are 89 million SMS send log records. These contain lots of REALLY boring metadata like delivery date, delivery delays, carrier and stuff
This is interesting info for criminals who want to do a large-scale Steam phishing campaign, but it's hardly a reason to change your Steam password or otherwise panic.
The demo data contains 3K entries from Portugal, but out of these, there are only 1.8K unique phone numbers. That's 60%, and judging from that subset of the actual data, there are probably at most 53M different phone numbers involved.

Furthermore, make sure to use unique passwords across all websites and services. When possible, make sure to enable 2FA as well.
