How do you convert real agent traces into reinforcement learning RL transitions to improve policy LLMs without changing your existing agent stack? Microsoft AI team releases Agent Lightning to help optimize multi-agent systems. Agent Lightning is a open-sourced framework that makes reinforcement learning work for any AI agent without rewrites. It separates training from execution, defines a unified trace format, and introduces LightningRL, a hierarchical method that converts complex agent runs into transitions that standard single turn RL trainers can optimize. What Agent Lightning does? The framework models an agent as a decision process. It formalizes the agent as a…

Aisuru, the botnet responsible for a series of record-smashing distributed denial-of-service (DDoS) attacks this year, recently was overhauled to support a more low-key, lucrative and sustainable business: Renting hundreds of thousands of infected Internet of Things (IoT) devices to proxy services that help cybercriminals anonymize their traffic. Experts say a glut of proxies from Aisuru and other sources is fueling large-scale data harvesting efforts tied to various artificial intelligence (AI) projects, helping content scrapers evade detection by routing their traffic through residential connections that appear to be regular Internet users. First identified in August 2024, Aisuru has spread to at…

Andy Cohen is always in his daddy era — but maybe now more than ever. During Cohen’s Wednesday, October 29, appearance on the “Call Her Daddy” podcast, host Alex Cooper commented on his longer hair, which led into a conversation about the Watch What Happens Live host’s recent transformation. “I, also, this summer lost some weight. I think that when your face is thinner, you can carry off longer hair better,” Cohen, 57, said, explaining that he’s “doing everything” after going on a bit of a health journey. “In May, I couldn’t button my suits. I was kind of at…

Michael Saylor, the co-founder of Strategy, the biggest Bitcoin (BTC) treasury company by holdings, forecast that Bitcoin would hit $150,000 by the end of 2025.“I think that these 12 months have probably been the best 12 months in the history of the industry,” Saylor told CNBC at the Money 20/20 conference in Las Vegas on Monday. Saylor cited the Securities and Exchange Commission (SEC) embracing tokenized securities, US Treasury Secretary Scott Bessent endorsing stablecoins to protect dollar dominance, and the overall regulatory pivot in the US as reasons to remain bullish. He said:“Our expectation right now is that by the end…

In computing, a denial-of-service attack (DoS attack; UK: /dɒs/ doss US: /dɑːs/ daas[1]) is a cyberattack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. -The Wikipedia definition of denial-of-service attack.  This is a very basic concept. Someone makes use of their own resources to disrupt the functioning of other machines on a network.  DoS attacks have been an issue for as long as the internet existed. One of the commonly argued “first Distributed Denial-of-service (DDoS) attacks” was against…

Affected configurations: geth 1.4.8 Likelihood: High Severity: High Details: An attack vector has been identified in the freshly released implementation of the DAO soft fork. The fork enactment code in geth (and other clients) allows execution of EVM code up to the block gas limit without paying for gas. This can slow down mining and prevent inclusion of legitimate transactions. The soft fork will not be enabled if the gas limit of block 1800000 is above 4000000 gas (i.e. if the community vote to activate the fork fails). The attack cannot be performed in this case. Effects on expected chain reorganisation depth: None Proposed temporary…
