Below, I emailed the “Trusting Trust” reference during our SG7 session on Circle in Prague, because SG7 was in the middle of discussing concerns about Circle’s approach of linking arbitrary libraries and executing them at compile time.

Since yesterday, I noticed the following tweets about Rust…

Tony “Abolish ICE” Arcieri 🦀 on Twitter: "Exfiltrating secrets with @rustlang macros: leveraging macro expansion in IDEs to exfiltrate secrets without compiling the code or even opening a file https://t.co/M2qhsfaLdX" / Twitter<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftwitter.com%2Fbascule%2Fstatus%2F1393228285056741376&data=04%7C01%7Chsutter%40microsoft.com%7C0c4586b71132437afdf408d917e9c9f5%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637567115143029064%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=onRXBBnDkqB1SbyYbfZ4lRvH5dbmubrTxX4aKvf4dOE%3D&reserved=0>

Björk on Twitter: "@hankadusikova ... Wait, what?

This sounds a lot like the same issue… is it?

(Ah, I just saw Hana’s tweet<https://twitter.com/hankadusikova/status/1393532440120074243?s=20> before hitting Send – yup, sounds like it is the same issue, thank you Hana.)

As we we think about extensible compilers and JITs, this is a classic paper worth remembering about supply chain issues with just ordinary closed compilers.
