Who knew that the combination of a person responding to car troubles by skateboarding to work, along with the beverage he consumed and the classic rock track he chose to complement a video post on TikTok would lead to a signature moment for the platform? No one could have possibly been prepared for this confluence...
Side-channel radio attacks just got a whole lot worse: a group of researchers from Eurecom's Software and Systems Security Group has extracted crypto keys from the noise generated by ordinary communications chips.Unlike more esoteric side-channels, which often need physical access to a target machine or some kind of malware implant, this leak comes from radio devices working as intended by the maker.If an SoC packs analogue and digital operations on the same die, the CPU's operations inevitably leak to the radio transmitter, and can be traced from a distance.As Tom Hayes of Eurecom wrote to El Reg in an email: “This type of leak is carried by the device's intended radio signal, and thus broadcast over a potentially longer distance” [than previous side-channel attacks].“In our work we have demonstrated over-the-air extraction of AES keys from a consumer-grade bluetooth device over a distance of 10 meters”, Hayes continued.The paper describing their work, “Screaming Channels: When Electromagnetic Side Channels Meet Radio Transceivers”, explains that the physical mechanism involved is very simple.
Tyson Foods' CEO Tom Hayes said that despite recent acquisitions, investments and expansions, the country's biggest meat packer is still looking to acquire other companies.The company has increased wages and is considering how to take advantage of automated and robotic functions at its facilities."That's exactly the reason we need to be spending more money on innovation.Hayes has spent his time as CEO expanding the company's operations beyond its core chicken, beef and pork operations into snacks and other proteins in demand with consumers.So far, that seems to mean diversification and innovation into prepared foods, plant-based products and cell-cultured meat production, which eliminates both slaughter and the environmental impact of traditional animal agriculture.Last April, Hayes oversaw the $4.2-billion purchase of AdvancePierre, a maker of ready-to-eat hamburgers, stuffed chicken breasts and other sandwiches supplied to restaurants, hospitals, schools as well as convenience stores and vending machines.
Most of the layoffs will occur at the company's headquarters in Springdale, Arkansas, and at corporate offices in Chicago and Cincinnati, the company said in a statement.“These are hard decisions, but I believe our customers and consumers will benefit from our more agile, responsive organization as we grow our business through differentiated capabilities, deliver ongoing financial fitness through continuous improvement and sustain our company and our world for future generations,” said Tom Hayes, Tyson’s president and chief executive officer.The company also said that due to a "much better than expected" profit from its beef segment, it was increasing its fiscal 2017 forecast for adjusted per-share earnings to between $5.20 and $5.30, up from $4.95 to $5.05 a share.Guidance for fiscal 2018 was set for adjusted earnings of $5.70 a share to $5.85 a share, while estimates had been $5.35.Tom Hayes, Tyson's CEO, said the restructuring is part of the company's "Financial Fitness" plans and an effort to show that it can operate more efficiently.Tyson did indicate that the synergies from integrating AdvancePierre Foods — a convenience and ready to eat sandwich and snacks company it bought earlier this year for $4.2 billion — plus shedding some other "non-value-added costs," were behind its strong savings projections during the next three fiscal years.
