Plus: State-sponsored AI hacking is here, Google hosts a CBP face recognition app, and more of the week's top security news. The United States issued a seizure warrant to Starlink this week related to satellite internet infrastructure used in a scam compound in Myanmar. The action is part of a larger US law enforcement interagency initiative announced this week called the District of Columbia Scam Center Strike Force. Meanwhile, Google moved this week to sue 25 people that it alleges are behind a "staggering" and "relentless" scam text operation that uses a notorious phishing-as-a-service platform called Lighthouse. WIRED reported this week that the US Department of Homeland Security collected data on Chicago residents accused of gang ties to test if police files could feed an FBI watchlist--and then, crucially, kept the records for months in violation of domestic espionage rules .

Consequently, evaluating models on test splits that might have leaked into the training set is prone to misleading conclusions.

Nonetheless, uncertainty estimation for non-independent node-level predictions is under-explored.

Is the fall of Pokrovsk inevitable? Is Trump losing patience with Putin? Will sanctions against Russian oil giants hurt Putin? Russia launched "massive" attacks on Ukraine's capital Kyiv, killing at least six people in the Desnianskyi district, the city's Mayor Vitali Klitschko wrote on Telegram. At least 35 people were also injured.

Hollywood's SAG Awards announces it will change its name The Screen Actors Guild Awards, the marquee awards ceremony honouring actors, is getting a new name. Known colloquially as the SAG Awards, the awards show will now be dubbed the Actor Awards presented by Sag-Aftra, the labour union representing US film, television and radio actors. Since the beginning, our statue has been called'The Actor' and we're a show that's entirely about actors, so this new name is a perfect next step in the show's evolution, the show's executive producer said on Friday. The rebrand comes ahead of the 32nd edition of the star-studded ceremony, which is set for 1 March 2026. The award show's executive producer Jon Brockett told the BBC that the name change - which was announced at a board meeting on Friday - gives viewers in more than 190 countries an immediate understanding of who we are and what we're about - a show about actors honouring actors.

Summary and Contributions: Summary & Contributions: Authors study the scopes of adversarial attacks in linear contextual bandit algorithms which have applications in a wide range of domains. The authors consider adversarial attacks on both reward and the context and analyze the robustness (or lack of it) of various contextual linear bandit algorithms including LinUCB, LinTS, epsilon-greedy etc. Empirical evaluations are presented on various synthetic and two real datasets to examine the effect of attacks on these algorithms. Strengths: The problem of analyzing the effect of adversarial attacks on bandit algorithms are indeed interesting and well motivated, and present work is supposedly the first one to analyze this for stochastic contextual linear bandits. Authors also analyze some popularly studied bandit algorithms, like LinUCB, LinTS, epsilon-greedy, and showed the attacking strategies (as optimization problems) to fool above algorithms for playing some targeted suboptimal arm majority number of times. Experiments are fairly detailed and reported on a large set of datasets showing the effect on learning rate of existing techniques on different degree+type of attacks.

The ongoing conflict in Ukraine is often described as the world's first drone war. It has led to a continuing huge growth in the production of military drones, both within and outside Ukraine. Before Russia's invasion of Ukraine Kseniia Kalmus was a floral artist. Now, she makes drones for use against the Russians. It was just an obvious decision for me, she tells the BBC from the Ukrainian capital.
