Rowhammer Attack Can Now Root Android Devices ( 100

An anonymous reader writes from a report via Softpedia: Researchers have discovered a method to use the Rowhammer RAM attack for rooting Android devices. For their research paper, called Drammer: Deterministic Rowhammer Attacks on Mobile Platforms, researchers tested and found multiple smartphone models to be vulnerable to their attack. The list includes LG Nexus (4, 5, 5X), LG G4, Motorola Moto G (2013 and 2014), One Plus One, HTC Desire 510, Lenovo K3 Note, Xiaomi Mi 4i, and Samsung Galaxy (S4, S5, and S6) devices. Researchers estimate that millions of Android users might be vulnerable. The research team says the Drammer attack has far more wide-reaching implications than just Android, being able to exploit any device running on ARM chips. In the past, researchers have tested the Rowhammer attack against DDR3 and DDR4 memory cards, weaponized it via JavaScript, took over PCs via Microsoft Edge, and hijacked Linux virtual machines. There's an app to test if your phone is vulnerable to this attack. "Rowhammer is an unintended side effect in dynamic random-access memory (DRAM) that causes memory cells to leak their charges and interact electrically between themselves, possibly altering the contents of nearby memory rows that were not addressed in the original memory access," according to Wikipedia. "This circumvention of the isolation between DRAM memory cells results from the high cell density in modern DRAM, and can be triggered by specially crafted memory access patterns that rapidly activate the same memory rows numerous times."

P.S. It's not a shameless self-plug if it's free, is it?!

Comment Re:Why do FOSS library folks hate ABI compatabilit (Score 0) 505

what libraries are you talking about? the kernel has kept binary compatibility with all programs virtually since it's inception. X11, GTK and KDE programs all run with very high levels of binary compatibility. on the rare instances they are changes, (say gtk2 to gtk3) it's a clear cutover and all ditros ship with both so all programs keep running.

what i believe you're referring to are the *internal* kernel ABIs. yes, this is a PITA for people writing drivers for video cards. but come on: that's not what you (nor i, nor 99.44% of the people here) do. more than a decade i've programmed on linux (GUIs, server-side, you name it). it all runs in userspace and code i wrote (and compiled) a decade ago still runs just fine on a modern kernel.

btw, if anyone needs convincing, type xbill into your "ubuntu software center" search bar. THAT program i fricking old. runs like a champ tho!

i agree that they {unity/gnome3} uselessly through away years of good UI engineering work. and i understand the need to move to clutter. but moving to a new framework is tough enough - don't try to re-invent the whole desktop paradigm while you're at it.

it's because i do trust the free market i want (good / common-sense) regulation. good regulations makes markets more free, not less. this is why we regulate "not throwing a brick through your competitor's storefront".

likewise, how robust do you think the air-conditioning equipment market would be if you're electric company was free to cap your Carrier-brand AC compressor's electricity usage but leave cap-free their own home-brand compressor?

one of their recruiters approached me last year to write a book on numpy. which was curious to me since while i've used it (and posted some very minor public code using it), i'm not a contributor, nor involved in the community in any way.

some googling led to some fairly consistent stories:
very little editing work
very low sales (rep told me 1000 copies would be considered successful for a sequel)
don't expect more than your initial front (~$3500, which isn't even a front; they pay it out over the different chapters you submit)
if they can they get multiple authors writing in the same category at the same time (which means you're basically competing against your own publisher)

needless to say: didn't want to sign my name to anything like that...
