Backdoor in XZ Utils That Almost Happened

Schneier on Security

Last week, the internet dodged a major nation-state attack that would have had catastrophic cybersecurity repercussions worldwide. It’s a catastrophe that didn’t happen, so it won’t get much attention—but it should. There’s an important moral to the story of the attack and its discovery : The security of the global internet depends on countless obscure pieces of software written and maintained by even more obscure unpaid, distractible, and sometimes vulnerable volunteers.

Weekly Update 394

Troy Hunt

I suggest, based on my experiences with data breaches over the years, that AT&T is about to have a very bad time of it. Class actions following data breaches have become all too common and I've written before about how much I despise them. The trouble for AT&T (in my non-legal but "hey, I'm the data breach guy" opinion), will be their denial of a breach in 2021 and the subsequent years in which tens of millions of social security numbers were floating around.

Security Vulnerability of HTML Emails

Schneier on Security

This is a newly discovered email vulnerability: The email your manager received and forwarded to you was something completely innocent, such as a potential customer asking a few questions. All that email was supposed to achieve was being forwarded to you. However, the moment the email appeared in your inbox, it changed. The innocent pretext disappeared and the real phishing email became visible.
