Ci si può fidare degli agenti? (Agents of Chaos)
by Enrico Nardelli April 7, 2026

April 7, 2026

We report an exploratory red-teaming study of autonomous language-model-powered agents deployed in a live laboratory environment with persistent memory, email accounts, Discord access, file systems, and shell execution. Over a two-week period, twenty AI researchers interacted with the agents under benign and adversarial conditions. Focusing on failures emerging from the integration of language models with autonomy, tool use, and multi-party communication, we document eleven representative case studies. Observed behaviors include unauthorized compliance with non-owners, disclosure of sensitive information, execution of destructive system-level actions, denial-of-service conditions, uncontrolled resource consumption, identity spoofing vulnerabilities, cross-agent propagation of unsafe practices, and partial system takeover. In several cases, agents reported task completion while the underlying system state contradicted those reports. We also report on some of the failed attempts. Our findings establish the existence of security-, privacy-, and governance-relevant vulnerabilities in realistic deployment settings. These behaviors raise unresolved questions regarding accountability, delegated authority, and responsibility for downstream harms, and warrant urgent attention from legal scholars, policymakers, and researchers across disciplines. This report serves as an initial empirical contribution to that broader conversation. https://arxiv.org/abs/2602.20021 -- -- EN https://www.hoepli.it/libro/la-rivoluzione-informatica/9788896069516.html ====================================================== Prof. Enrico Nardelli Past President di "Informatics Europe" Direttore del Laboratorio Nazionale "Informatica e Scuola" del CINI Dipartimento di Matematica - Università di Roma "Tor Vergata" Via della Ricerca Scientifica snc - 00133 Roma home page: https://www.mat.uniroma2.it/~nardelli blog: https://link-and-think.blogspot.it/ tel: +39 06 7259.4204 fax: +39 06 7259.4699 mobile: +39 335 590.2331 e-mail: nardelli(a)mat.uniroma2.it online meeting: https://blue.meet.garr.it/b/enr-y7f-t0q-ont ====================================================== --

Roio, "La verifica dell’età in rete non solo non protegge i minori, ma ci mette tutti a rischio"
by J.C. DE MARTIN April 4, 2026

April 4, 2026

*La verifica dell’età in rete non solo non protegge i minori, ma ci mette tutti a rischio* /Pensata come misura di tutela, la verifica dell’età rischia di creare più problemi di quanti ne risolva, tra inefficacia, perdita di privacy e maggiore centralizzazione del controllo online / Denis "Jaromil" Roio 31 marzo 2026 I governi di mezzo mondo stanno imponendo la *verifica dell’età* <https://www.wired.it/article/verifica-delleta-spiegazione-colossi-online-de…> *per un crescente numero di servizi su Internet*, come una misura di tutela per i minori. In realtà stanno *aggravando la raccolta di dati su tutto quel che facciamo in rete*, usando argomenti che confondono la moderazione dei contenuti con il ruolo educativo di genitori e scuole. Di verifica dell’età obbligatoria per l'accesso a certi servizi di rete se ne parla da tanto. Dovrebbe servire, si dice spesso, a limitare *l'accesso dei minori alla pornografia*, al gioco d'azzardo o a contenuti particolarmente espliciti. Ma in un numero crescente di casi *i controlli si stanno estendendo* a social network, piattaforme video, servizi di messaggistica, giochi e motori di ricerca e perfino agli stessi sistemi operativi che girano su computer e telefonini.

LLMs e copyright
by Enrico Nardelli April 3, 2026

April 3, 2026

Per chi se li fosse persi: un paio di lavori che indicano in modo abbastanza chiaro come gli LLM siano certamente delle gigantesche memorie che contengono intere opere soggette a diritto d'autore. Ciao, Enrico 1) Extracting books from production language models hmed Ahmed, A. Feder Cooper, Sanmi Koyejo, Percy Liang https://arxiv.org/abs/2601.02671 Many unresolved legal questions over LLMs and copyright center on memorization: whether specific training data have been encoded in the model's weights during training, and whether those memorized data can be extracted in the model's outputs. While many believe that LLMs do not memorize much of their training data, recent work shows that substantial amounts of copyrighted text can be extracted from open-weight models. However, it remains an open question if similar extraction is feasible for production LLMs, given the safety measures these systems implement. We investigate this question ... and we measure extraction success with a score computed from a block-based approximation of longest common substring (nv-recall). With different per-LLM experimental configurations, we were able to extract varying amounts of text. ... e.g, nv-recall of 76.8% and 70.3%, respectively, for Harry Potter and the Sorcerer's Stone ... Taken together, our work highlights that, even with model- and system-level safeguards, extraction of (in-copyright) training data remains a risk for production LLMs. ---------------- 2) Xinyue Liu, Niloofar Mireshghallah, Jane C. Ginsburg, Tuhin Chakrabarty Alignment Whack-a-Mole : Finetuning Activates Verbatim Recall of Copyrighted Books in Large Language Models https://arxiv.org/abs/2603.20957 Frontier LLM companies have repeatedly assured courts and regulators that their models do not store copies of training data. They further rely on safety alignment strategies via RLHF, system prompts, and output filters to block verbatim regurgitation of copyrighted works, and have cited the efficacy of these measures in their legal defenses against copyright infringement claims. We show that finetuning bypasses these protections: by training models to expand plot summaries into full text, a task naturally suited for commercial writing assistants, we cause GPT-4o, Gemini-2.5-Pro, and DeepSeek-V3.1 to reproduce up to 85-90% of held-out copyrighted books, with single verbatim spans exceeding 460 words, using only semantic descriptions as prompts and no actual book text. ... Our findings offer compelling evidence that model weights store copies of copyrighted works and that the security failures that manifest after finetuning on individual authors’ works undermine a key premise of recent fair use rulings, where courts have conditioned favorable outcomes on the adequacy of measures preventing reproduction of protected expression. -- -- EN https://www.hoepli.it/libro/la-rivoluzione-informatica/9788896069516.html ====================================================== Prof. Enrico Nardelli Past President di "Informatics Europe" Direttore del Laboratorio Nazionale "Informatica e Scuola" del CINI Dipartimento di Matematica - Università di Roma "Tor Vergata" Via della Ricerca Scientifica snc - 00133 Roma home page: https://www.mat.uniroma2.it/~nardelli blog: https://link-and-think.blogspot.it/ tel: +39 06 7259.4204 fax: +39 06 7259.4699 mobile: +39 335 590.2331 e-mail: nardelli(a)mat.uniroma2.it online meeting: https://blue.meet.garr.it/b/enr-y7f-t0q-ont ====================================================== --

[Responsible AI] Algorithmic Insurance, Agni Orfanoudaki, Saïd Business School, Oxford University
by Daniele Quercia March 26, 2026

March 26, 2026

Algorithmic Insurance Agni Orfanoudaki, Saïd Business School, Oxford University Join MS Teams<https://teams.microsoft.com/meet/34363600242348?p=ChcPJFeEayAKJ4UBuJ> Format: 35 min talk + 25 min Q&A Abstract: Measuring and managing the risks associated with artificial intelligence (AI) is increasingly critical as AI systems are integrated into high-stakes decision-making environments, such as healthcare. Algorithmic insurance offers a scalable financial solution for quantifying, pricing, and managing the risks inherent in AI deployment, complementary to regulation. It provides a structured mechanism for transferring the risks associated with AI systems from developers and users to insurers, creating a financial buffer that incentivizes responsible AI use and mitigates liability. Our work formalizes the concept of algorithmic insurance and proposes quantitative frameworks to estimate the risk exposure of insurance contracts for machine-driven financial risk. Bio: Agni Orfanoudaki is an Associate Professor of Operations Management at the Saïd Business School of Oxford University. Alongside her role, Agni is a Management Studies Fellow at Exeter College and a visiting scholar at the Harvard Kennedy School as a Harvard Data Science Initiative Fellow. She leads the Data-Driven Decisions Lab (3DL) at Oxford, conducting theoretical and empirical research with machine learning, optimization, and stochastic processes with applications to healthcare and insurance. Prior to joining Oxford, Agni received a PhD in Operations Research from the Massachusetts Institute of Technology. She has collaborated with numerous institutions, including a major medical society, two international reinsurance companies, and more than eight hospitals in the US and Europe.

AI got the blame for the Iran school bombing. The truth is far more worrying
by Alberto Cammozzo March 26, 2026

March 26, 2026

Articolo molto interessante sull'industrializzazione della guerra (o meglio, della morte) e sul ruolo delle tecnologie in questo processo. <https://www.theguardian.com/news/2026/mar/26/ai-got-the-blame-for-the-iran-…> Questo passaggio illumina l'ideologia che sta dietro alla /killchain/ come anche ai licenziamenti di Amazon trattati nel precedente messaggio di Juan Carlos, e ne evidenzia la logica prettamente industriale mirante al controllo e alla eliminazione di ogni conoscenza tacita e non codificata: In 1984, the historian David Noble showed that when the US military and American manufacturers automated their factory floors, they consistently chose systems that were slower and more expensive but which moved decision-making away from workers and into management. The point was not efficiency – it was frequently extremely wasteful – but control. A worker who understands what they are doing can exercise judgment the institution cannot govern. Move that understanding into the system, and the worker has nothing left to do but follow instructions. Alex Karp, the CEO of Palantir, describes exactly this achievement in his 2025 book, The Technological Republic. “Software is now at the helm,” he writes, with hardware “serving as the means by which the recommendations of AI are implemented in the world.” His model for what this should look like comes from nature: bee swarms and the murmurations of starlings. “There is no mediation of the information captured by the scouts once they return to the hive,” Karp writes. The starlings need no permission from above, they require “no weekly reports to middle management, no presentations to more senior leaders, no meetings or conference calls to prepare for other meetings”. This sounds liberating, even utopian. But the signal that passes without mediation is also the signal that nobody can question. Karp thinks he is destroying bureaucracy. He is encoding it. The contempt for meetings and weekly reports and presentations to senior leaders; he treats these as the bureaucratic process itself. They are not. They were where people interpreted procedure, the place where someone could notice when categories no longer fit the case. The targeting doctrine is still there. They are columns on a workflow board now, stages a target passes through on its way to being struck. What Karp eliminated was the discretion the institution could never admit it depended on. What remains is a bureaucracy that can execute its rules but with no one left to interpret them. Bureaucracy encoded in software does not bend. It shatters. Ciao, Alberto
