iTWire - Did Optus suffer another data breach before the big one?
Did Optus suffer another data breach before the big leak, one that has gone generally unmentioned and unnoticed? At least one security professional who has been closely following the incidents at the telco appears to think so.
Brett Callow pointed out in a tweet that a post — on the same forum where claims of the breach of 11.2 million users were put up — dated 17 September offered 1.1 million names and email addresses of Optus customers. It has now been removed.

Securing Open Source Software Act of 2022
A bill was recently introduced in the US Senate, entitled the Securing Open Source Software Act of 2022.
I don’t usually write much about pending legislation, because it often does not ever become law, or changes substantially before it becomes law. This bill is unlikely to be passed this year because of its timing.

Testing shows AMD Zen 4 handling Spectre, Retbleed mitigations like a real champ - Neowin
At the end of August, AMD unveiled its Ryzen 7000 series desktop CPU lineup based on the Zen 4 micro-architecture. And although the excitement around it has been somewhat muddled down by Intel's 13th Gen Raptor Lake-S lineup which has come out guns blazing with lower prices, it does look like Zen 4 also has some redeeming qualities that enthusiasts would be keen to consider.
Fellow media outlet Phoronix decided to test the new Ryzen 9 7950X, which is the flagship Ryzen 7000 SKU, with the various CPU vulnerability mitigations and more turned on and off. And the results are somewhat surprising in a good way for AMD.
