Attention Required! | Cloudflare

The only silver lining here is that all of the datasets were exposed only briefly: long enough for researchers to uncover them, but not long enough to find who was controlling vast amounts of data. Most of the datasets were temporarily accessible through unsecured Elasticsearch or object storage instances.

So there isn't really an explanation other than "somebody collected these somehow and left the data unsecured."

The attack vector for infostealer malware is usually social engineering, getting unwary users to download infected trojanized software via phishing and malvertising etc.

If you follow security news, you will see articles about infostealer malware campaigns all the time.

Aaaah! Act now! Hurry! Change ALL your passwords! Your password was stolen by malware on your device so change it now... on your device... that still has malware... Wait a minute. Shouldn't this article at least suggest removing the malware first?

This passage reads 100% like AI wrote. Right down to the over used turns of phrase that AI inserts into every output to the prompts you give it

It’s probably your fault, you loved em dashes too much that AI started using them after stealing all your content

I need more information. How is the malware being distributed to these devices? How can we check if our credentials are in this dump? Shouldn't the respective platforms be doing due diligence to notify those effected and asking them to change their passwords?

I feel it may be fairly likely that this inforstealer Malware is the type distributed by dubious apps the play store and similar have had to take down but aren't actively notifying users who installed them. Is it predominantly phones that are effected or is this malware PC based? Changing your passwords is important but sounding the alarm with no actual information is just... Ill advised. It's fear mongering.

Oh, so I'm probably safe.

I don't do mainstream social media, and I don't answer phone calls, texts, or emails from unknown sources.

Mama told me not to talk to strangers, and I took that into the digital age.

What's the total human population again, 8 billion?

I don't know about you, but I have 2 Apple accounts, 2 Facebook accounts, and like 9 Google accounts. I know I'm above average, but it's not hard to have 1 of each for normal uses.

Reads more like an advertorial. Low on detail, high on "passkeys are the future", and plenty of typos.

Yeah, what’s with the spaces? I’ve been an emdash slut for 20 years, but I’ve never put spaces on either side. I’ve also scarcely seen anyone else do that, until LLMs became popular.

What you say?

I was going to say "I don't use em-dashes in my books for when they sole all those books" but then I went into my first book and found 22 em-dashes so... oops. I thought the word processor changed -- into an en-dash and not an em-dash.

Windows Defender is absolutely useless and Malwarebytes is only slightly better. I’d recommend Bitdefender, and make sure it’s installed on a freshly erased computer. Digital security is an arms race and the bad guys are winning.
