Toot

My #FlippyRAM USB pen drive which was handed out during the Rowhammer talk at #38C3 has Vendor ID 0x346d=13421d and Product ID 0x5678. If https://usb.org/sites/default/files/vendor_ids051920_0.pdf is the most recent account then this doesn't look like an officially registered VID. My Linux displays a "USB Disk 2.0". It actually enumerates as "Mass Storage" device. PID of 0x5678 also really reads like a dummy value though 0x38c3 would have been even nicer. Probably really just some cheap-o pen drives from $somewhere?

The device model is "VendorCo ProductCode". ¯_(ツ)_/¯

7.5 GiB in total. Two partitions (~1 GiB + ~10 MiB + ) with fat32 filesystems on them. A big part is unallocated. I wonder if some easter eggs have been hidden there? First partition is labeled "ARCH_202412".

"When the only tool you have is a hammer, everything looks like a nail." Turns out my laptop is a train grid power driven hammer now. All for science! 💻🔨 (Please note: minimum runtime is 3 hours just in case you are also on travel and dare to run this.)

Oh nice, they updated the website with hints about their #38c3 talk. And details alt how to verify the USB pen drive firsthand. Well, I took a backup and a hash of the drive, but it's currently not accessible as my laptop is already hammering. 😅
