If you haven't shored up that Citrix hole, you were probably hacked over the weekend: Exploit code now available

I am sure lots of mathematicians are currently working on famous problems without telling anybody. Is this a good aspect of the culture of mathematics? Maybe if all the mathematicians working secretly on the Riemann hypothesis got together and compared notes, they could solve it.

I also added an overview table with all projects that I know of using SGX-Step. I'm planning to keep this list up-to-date. Feel free to reach out if you know of other projects that are not listed below!

SGX-Step v1.4.0 released with support for x86 ring-0 interrupt handlers and call gates! Allows to build a mini-OS for side-channel research, including easily executing selected functions from a user-space program in privileged ring-0 :-)

Not sure if reducing number of rounds makes sense Impact on side-channel attacks?

Jean-Baptiste Bédrune on breaking HSMs . Not much has been done like this in the past. Why? (1) It's expensive. (2) HSM vendors don't give any information at all; zero transparency. (My opinion - the latter is the main reason.)

FPGA cards can be abused for faster and more reliable Rowhammer attacks * Academics detail new JackHammer attack * Twice as fast, 4 times more bit flips than Rowhammer * FPGAs are commonly used in cloud services, but don't have same security as CPUs

Our attack "JackHammer" sounds even cooler if you pronounce it with a French accent :)

An interesting paper that was just published in collab w/ Intel showing side-chan defense is critical for FPGAs & other accelerators. They demo 'JackHammer', novel hardware attacks between the mem I/F of the FPGA & host CPU. It's faster & more reliable.

In 1935, after the famous Einstein-Podolsky-Rosen paper arguing that quantum mechanics was incomplete, Schrödinger wrote to Einstein: "I am very happy that in the paper just published in Physical Review you have evidently caught dogmatic q.m. by the coat-tails". (1/n)
