Cyber Espionage Alert: LilacSquid Targets IT, Energy, and Pharma Sectors

Posted by in category: energy

A previously undocumented cyber espionage-focused threat actor named LilacSquid has been linked to targeted attacks spanning various sectors in the United States (U.S.), Europe, and Asia as part of a data theft campaign since at least 2021.

“The campaign is geared toward establishing long-term access to compromised victim organizations to enable LilacSquid to siphon data of interest to attacker-controlled servers,” Cisco Talos researcher Asheer Malhotra said in a new technical report published today.

Targets include information technology organizations building software for the research and industrial sectors in the U.S, energy companies in Europe, and the pharmaceutical sector in Asia, indicating a broad victimology footprint.

Data-driven model generates natural human motions for virtual avatars

Posted by in category: robotics/AI

Humans can innately perform a wide range of movements, as this allows them to best tackle various tasks in their day-to-day life. Automatically reproducing these motions in virtual avatars and 3D animated human-like characters could be highly advantageous for many applications, ranging from metaverse spaces to digital entertainment, AI interfaces and robotics.

Researchers at Max Planck Institute for Intelligent Systems and ETH Zurich recently developed WANDR, a new model that can generate natural human motions for avatars. This model, to be introduced in a paper presented at the Conference on Computer Vision and Pattern Recognition (CVPR 2024) in June, unifies different data sources under a single model to attain more realistic motions in 3D humanoid characters. The paper is also posted to the arXiv preprint server.

“At a high-level, our research aims at figuring out what it takes to create able to behave like us,” Markos Diomataris, first author of the paper, told Tech Xplore. “This essentially means learning to reason about the world, how to move in it, setting goals and trying to achieve them.

Scientists achieve giant magneto-superelasticity in metal crystal

Posted by in category: futurism

Recently, a research group developed a giant magneto-superelasticity of 5% in a Ni34Co8Cu8Mn36Ga14 single crystal. This was achieved by introducing arrays of ordered dislocations to form preferentially oriented martensitic variants during the magnetically induced reverse martensitic transformation.
