24hrs notice is unheard of. Who works for CTS-Labs? Attaching your name to a company like that should disqualify you from any future jobs in the security space.

Who do you think you speak for? Assuming the vulnerabilities aren't fabricated --- it's happened before with other companies --- attaching your name to that white paper probably guarantees you lifetime employment in security research.

"Unheard of"? People have dropped serious vulnerabilities with _zero_ warning before.

Earlier quoted context omitted.

Yeah it's suspicious. The website[1] has many fancy infographics, marketable names and fear mongering but you have to dig into the whitepaper[2] to find any details about the actual vulnerabilities. And even then it starts only on page 8 of 20 and you discover that it's vulnerabilities targeting the secure boot infrastructure and you need local admin to exploit them. It's not good but it's not a new Spectre or Meltdo…

It's possibly even more nefarious than that: 1) execute a series of puts on AMD, 2) release exploit 3) profit. If you execute an option with a far time horizon and give the company enough time to mitigate their vulns, then I think this is not an irresponsible thing to do (as it incentivises the company to actually do something), but with 24 hours notice...

Seeing as CTS-Lab's CFO also founded a hedge fund you're probably on the right track.

>Yaron co-founded CTS-Labs in 2017, and previously served as an intelligence analyst in the Israeli Intelligence Corps Unit 8200. He is also the founder and Managing Director of NineWells Capital, a hedge fund that invests in public equities internationally. He holds a B.A. and M.A. from Yale University.

> AMD is in the process of responding to the claims, but was only given 24 hours of notice rather than the typical 90 days for standard vulnerability disclosure. No official reason was given for the shortened time. 90 days is not a standard. Nothing was shortened. People are allowed to publish their research whenever they like. Vendor advance notification is optional. Full, immediate disclosure is responsible.

No it isn't, not even slightly. This is completely irresponsible. They are publishing a zero day vulnerability. Completely unprofessional and reckless.

Fortunately for us all the actual exposure is minimal.

It sounds like creating a website and priming media was a higher priority than informing AMD.

It also seems like that you could make security claims and then perform market manipulation on the stock. Giving yourself 24 hours lead time and making AMD look bad would allow you to short the stock. It doesn't seem like it has impacted the stock at all though.

Why does it say this on the disclaimer:

"...we may have, either directly or indirectly, an economic interest in the performance of the securities of the companies whose products are the subject of our reports."

Are they shorting AMD? https://amdflaws.com/disclaimer.html

The title here is misleading. The vulnerabilities were not actually publicly disclosed, the only thing that was disclosed publicly is the fact that the vulnerabilities exist. The actual details of the vulnerabilities were disclosed privately with AMD.

What's wrong with full disclosure? Ryzen owners ought to be informed ASAP that they're (possibly) vulnerable.
