ROWHAMMER ATTACK DEMONSTRATED AGAINST NVIDIA GPU

A group of researchers from the University of Toronto demonstrated that the Rowhammer attack method can be applied to GPUs in an attack they dubbed GPUHammer. Rowhammer attacks involve repeatedly accessing (“hammering”) a DRAM row, leading to electrical interference that causes bit flips in adjacent memory regions. The researchers have demonstrated that GPUHammer attacks can reduce the accuracy of ML models from 80% to 0.1%.

COINBASE SUES OREGON GOVERNOR OVER POLICY SHIFT

Coinbase has filed suit against Oregon Governor Tina Kotek, accusing her office of withholding records tied to a surprise state lawsuit that reclassified crypto as securities after previously stating otherwise. The exchange claims this abrupt policy shift was made behind closed doors, bypassing the legislative process, and unfairly targets only Oregon residents. Coinbase's lawsuit comes as federal lawmakers move toward formal crypto legislation, including the GENIUS and Clarity bills expected to reach President Trump's desk later this month.

A NEVER-ENDING SUPPLY OF DRONES HAS FROZEN THE FRONT LINES IN UKRAINE

Drones are dominating the battlefield in the fight for Ukraine. Both sides have hundreds of them constantly in the air across the 750-mile front line. Drones can lay mines, deliver ammunition and medication, and even evacuate wounded or dead soldiers. They are being used to spot movement along the front line and dispatched to strike enemy troops and vehicles. Drones are so cheap to make that both sides can expend them on any target, including individual soldiers. Due to their size and speed, they are difficult to shoot down, so the main defense against them has been electronic jamming systems - but these can be overcome with fiber-optic drones.
