Much Ado About Nothing?

We live in a world seemingly fueled by explosive headlines. This morning we were welcomed with a proclamation that AMD has 13 newly discovered security flaws in their latest Ryzen/Zen chips that could potentially be showstoppers for the architecture, and AMD’s hopes that it can regain lost marketshare in mobile, desktop, and enterprise markets. CTS-Labs released a report along with a website and videos explaining what these vulnerabilities are and how they can affect AMD and its processors.

This is all of course very scary. It was not all that long ago that we found out about the Spectre/Meltdown threats that seemingly are more dangerous to Intel than to its competitor. Spectre/Meltdown can be exploited by code that will compromise a machine without having elevated privileges. Parts of Spectre/Meltdown were fixed by firmware updates and OS changes which had either no effect on the machine in terms of performance, or incurred upwards of 20% to 30% performance hits in certain workloads requiring heavy I/O usage. Intel is planning a hardware fix for these vulnerabilities later on this year with new products. Current products have firmware updates available to them and Microsoft has already implemented a fix in software. Older CPUs and platforms (back to at least 4th Generation Core) have fixes, but they were rolled out a bit slower. So the fear of a new exploit that is located on the latest AMD processors is something that causes fear in users, CTOs, and investors alike.

CTS-Labs have detailed four major vulnerabilities and have named them as well as have provided fun little symbols for each; Ryzenfall, Fallout, Masterkey, and Chimera. The first three affect the CPU directly. Unlike Spectre/Meltdown, these vulnerabilities require elevated administrative privileges to be run. These are secondary exploits that require either physical access to the machine or logging on with enhanced admin privileges. Chimera affects the chipset designed by ASMedia. It is installed via a signed driver. In a secured system where the attacker has no administrative access, these exploits are no threat. If a system has been previously compromised or physically accessed (eg. force a firmware update via USB and flashback functionality), then these vulnerabilities are there to be taken advantage of.

In every CPU it makes AMD utilizes a “Secure Processor”. This is simply a licensed ARM Cortex A5 that runs the internal secure OS/firmware. The same cores that comprise ARM’s “TrustZone” security product. In theory someone could compromise a server, install these exploits, and then remove the primary exploit so that on the surface it looks like the machine is operating as usual. The attackers will still have low level access to the machine in question, but it will be much harder to root them out.

Beating AMD and Analyst Estimates

January 30th has rolled around and AMD released their Q4 2017 results. The results were positive and somewhat unexpected. I have been curious how the company fared and was waiting for these results to compare them to the relatively strong quarter that Intel experienced. At the Q3 earnings AMD was not entirely bullish about how Q4 would go. The knew that it was going to be a down quarter as compared to an unexpectedly strong third quarter, but they were unsure how that was going to pan out. The primary reason that Q4 was not going to be as strong was due to the known royalty income that AMD was expecting from their Semi-Custom Group. Q4 has traditionally been bad for that group as all of their buildup for the holiday season came from Q1 and Q2 rampings of the physical products that would be integrated into consoles.

The results exceeded AMD’s and analysts’ expectations. They were expecting in the $1.39B range, but their actual revenue came in at a relatively strong $1.48B. Not only was the quarter stronger than expected, but AMD was able to pull out another positive net income of $61M. It has been a while since AMD was able to post back to back profitable quarters. This allowed AMD to have a net positive year to the tune of $43M where in 2016 AMD had a loss of $497M. 2017 as a whole was $1.06B more in revenue over 2016. AMD has been historically lean in terms of expenses for the past few years, and a massive boost in revenue has allowed them to invest in R&D as well as more aggressively ramp up their money making products to compete more adequately with Intel, who is having their own set of issues right now with manufacturing and security.
