Feedback & Followups

  • In the previous instalment we joined in the mockery of a Chinese railroad company that relied on Flash for their operations. Listener Tom Merit got in touch with a follow-up article which casts some doubt on the details of the Apple Daily report we linked to — it seems the problem did not stop them dispatching trains, and the fix was not a pirated version of Flash, but an older version without the self-deactivating code. They do still deserve quite a bit of mockery regardless IMO —…
  • In the previous instalment we mentioned that based on Apple’s infamous FaceTime bug a security researcher had found similar bugs in other apps and got those responsibly fixed. We’ve since learned that the same research has also revealed how Apple responded in the long-term – they completely re-architected FaceTime to harden it dramatically with a new kind of extra secure sandboxing arrangement they’ve codenamed BlastDoor (Editorial by Bart: I’m really impressed with what Apple have done, very clever!) —… &…

Deep Dive — Bloomberg Follows up on its Sensationalistic “The Big Hack” Story from 2018 (Opinion)

This entire segment is opinion, but here’s the link to the piece if you’d like to read it yourself: The Long Hack: How China Exploited a U.S. Tech Supplier —…

What made the original story such big news is the report that there were spying chips inserted into an entire line of popular products used in data centres around the world by massive cloud providers like Amazon and Apple. The authors hadn’t been able to find any actual chips, so they illustrated their piece with an artist’s impression of what one might look like, and the entire US security apparatus and the companies involved all issued strenuous denials of the story.

Back in 2018 when the authors were criticised for publishing such a big allegation without any actual evidence, they replied confidently that now the story was out it would just be a matter of time until the evidence flowed in as these chips started to be found all over the place. That never happened, and still hasn’t!

This new article never admits the old one was wrong. It never retracts the unfounded chip allegations, but it also doesn’t provide any new evidence to support the original claim. Instead, in a bait-and-switch maneuver, the article instead describes highly targeted malicious firmware attacks by nation-states against each other’s interests. That’s neither surprising nor news, and it wouldn’t have been either in 2018 either.

We know governments and their operatives are using highly targeted supply-chain attacks, and have known that for years. It’s nice to see an example of this described in detail, but it does not justify the original publication of the utterly unsupported and hyperbolic original piece back in 2018, nor does it justify Bloomberg’s continuing refusal to retract that sensationalistic nonsense.

I’m in complete agreement with Jon Gruber’s scathing criticism. This quote sums up my opinion nicely:

“It’s a 4,000-word exercise in journalistic sophistry. It creates the illusion of something being there, but there is nothing there. The only good purpose this report could serve is as source material for a class on critical thinking.”
