5/10 Are We Susceptible to Rowhammer? An End-to-End Methodology for Cloud Providers https://t.co/Rq2mPwMEL8 Rowhammer again! You can actually do much better and hammer DRAMs at an optimal rate. @LCojocar et al. @_onurmutlu_ @IEEESSP

[Lucian Cojocar @LCojocar]

@sirmc @vu5ec @IEEESSP Thanks! This would not have been possible without the Rowhammer knowledge that is available in @vu5ec. I think everyone helped me getting over the reverse-engineering-induced gloominess :-).

Still a few days to apply for the assistant/associate prof position in security at @vu5ec (https://t.co/xKzRCZfipI). Explicitly also open for promising _young_ researchers. Also in other areas of security. Do not feel shy about applying!

Reverse Engineering of Error-Correcting Codes by @LCojocar https://t.co/r2viEkgcsZ

[Lucian Cojocar @LCojocar]

@kavehrazavi That's true. And sometimes, reverse engineering doesn't get enough credit in our work. E.g., "We bypassed the memory initialization by reverse engineering and modifying the parts of the binary BIOS code that performs DRAM initialization" hides many man-hours work.

@kavehrazavi Reverse engineering can be depressing and quite solitary. The support from all of you @vu5ec was always there :-), I appreciate the encouragement that I got throughout the process. It was painfully fun!

[VUSec @vu5ec]

Our #ECCploit work demonstrating #Rowhammer exploits on #ECC-enabled systems (along with its companion #SP19 paper) is now officially public @LCojocar @kavehrazavi @c_giuffrida @herbertbos! Check out our project page and the paper: https://t.co/yhvmML5hXp

We’ve released the first Security Overview for the Apple T2 Security Chip! Mac secure boot, storage encryption, and more, e.g.: “Mac portables with the T2 chip have a hardware disconnect that ensures the microphone is disabled when the lid is closed.”

Have a look at @Microsoft Server Board Schematic and super complex #PCB Layout designed in @Cadence. I will point out some interesting stuff. Watch the Part 1 here: https://t.co/52fHElhwkm

Nice reverse engineering work.

The Intel 8087 floating point chip contained an unusual high-density ROM. It stored 2 bits per transistor by using four different transistor sizes. I look inside the chip and explain how it works in my article:

My die photos of the @Intel 8087 floating point chip from 1980. Almost all floating point is based on this chip and today's desktop computers still run 8087 instructions. I reverse engineered the bias generator inside and explain how it works.

Electromagnetic side channels from a CPU can leak to a radio transmitter. CPU and radio transmitters are often integrated (think WiFi, BlueTooth)
