a surprisingly disappointing article from ars, i expect better from them.

the author appears to be confusing “relay attacks” with “cloning” and doesn’t really explain the flow of the attach that well.

really this just sounds like a complicated MitM attack, using the victim’s phone as the “middle” component between the victim’s physical card and the attacker’s rooted phone.

the whole “cloning the UID attack” at the end of the article is irrelevant, NFC payment cards don’t work like that.

Microsoft creates secure boot: “we should be able to run whatever we want on our hardware!”

Microsoft lets users install crowdstrike on their computer: “Microsoft shouldn’t let us run this on our hardware!”

faster can still lead to battery life improvements. if the CPU is able to complete tasks in less time, it can then enter a lower power state sooner which will result in less battery usage overall

assuming you have a GNU toolchain you can use the find command like so:

find . -type f -executable -exec sh -c '
case $( file "$1" ) in (*Bourne-Again*) exit 0; esac
exit 1' sh {} \; -print0 | xargs -0 -I{} cp {} target/

This first finds all executable files in the current directory (change the “.” arg in find to search other dirs), uses the file command to test if it’s a bash file, and if it is, pipes the file name to xargs which calls cp on each file.

note: if “target” is inside the search directory you’ll get output from cp that it skipped copying identical files. this is because find will find them a free you copy them so be careful!

note 2: this doesn’t preserve the directory structure of the files, so if your scripts are nested and might have duplicate names, you’ll get errors.

why use docker here? you’re just adding layers of abstraction in an environment that can’t seem to really support them.

that said, switching to 32bit linux, if the VPS supports it, will save you memory.
