Conferenza Sicurezza e Privacy 2026
Il POuL è orgoglioso di presentare anche quest’anno la Conferenza Sicurezza e Privacy , giunta alla sua nona edizione! Come da tradizione, saranno affrontati temi di attualità nel campo della sicurezza informatica con il contributo di esperti del settore. Quest’anno la conferenza sarà divisa in due giornate ciascuna con due interventi. Prima giornata Il primo intervento, dal titolo “AI e privacy: ma se il modello ce lo self-hostiamo?” , sarà a cura di Alessandro di Federico : ex-studente del Politecnico di Milano, co-fondatore e CEO di rev.ng, piccola compagnia milanese dedita al reverse engineering . Durante l’incontro, spiegherà come usare tecnologie open-weight per installare e utilizzare tecnologie LLM. Dopo un breve impianto teorico, seguiranno applicazioni pratiche come fare trascrizioni di audio con Whisper, creare immagini in stile studio ghibli e chattare con LLM, anche di grandi dimensioni. A seguire, il talk “Biglietti e tessere ATM: evoluzione e sicurezza” , tenuto da Jacopo Jannone , attualmente assunto come Offensive Security Engineer. Nel tempo libero partecipa a iniziative come Tower of Hanoi e mHACKeroni , oltre a contribuire a progetti liberi e Open Source. Il suo intervento sarà un’analisi approfondita delle tecnologie usate nel sistema tariffario delle principali compagnie di trasporto pubblico lombarde (ATM e Trenord). Partendo da un lavoro di reverse engineering approfondito, ricostruirà il funzionamento di un’infrastruttura che tutti usano, ma che in pochi hanno osservato davvero da vicino. La prima giornata si svolgerà lunedì 20 aprile dalle 17:15 alle 19:30, presso il campus Leonardo del Politecnico di Milano, edificio 13 (Trifoglio), in aula T.1.3. Seconda giornata Il primo intervento verrà presentato dal Prof. Alessandro Barenghi , Professore associato presso il Politecnico di Milano e ricercatore presso il Dipartimento di Elettronica, Informazione e Bioingegneria (DEIB) dell’Ateneo. I suoi interessi di ricerca comprendono la sicurezza informatica, con una particolare attenzione agli attacchi side-channel e a soluzioni crittografiche post-quantum. Il suo talk, dal titolo Chissà dove ho lasciato le chiavi… - Confidenzialità e accesso forzato a dati cifrati , tratterà in maniera generale su metodi per violare la confidenzialità di dati cifrati senza la chiave, cercando di mettere in luce rischi e benefici delle varie soluzioni. L’ultimo intervento sarà tenuto dalla Prof.ssa Chiara Graziani della Bocconi , attualmente professoressa assistente presso l’Università commerciale Luigi Bocconi, dove si dedica alla didattica in vari corsi nel campo della giurisprudenza. Il suo intervento, dal titolo “Dal GDPR all’AI Act: le nuove frontiere dei diritti digitali nell’Unione europea” , esplorerà l’evoluzione dei rapporti tra l’istituzione Europea e il diritto della privacy. In particolare, verrà approfondito il modo in cui l’impatto delle reti informatiche ha sconvolto la relazione tra utente singolo e big data. La seconda giornata si terrà mercoledì 29 aprile e dalle 17:15 alle 19:30, presso il campus Leonardo del Politecnico di Milano, edificio 13 (Trifoglio), in aula T.1.3. — Ricordiamo che l’ingresso è libero e gratuito, e che non è necessario registrarsi per partecipare. L’evento sarà anche trasmesso in diretta sul nostro canale YouTube , e forniremo il link alla diretta sul nostro canale Telegram qualche minuto prima dell’inizio di ogni giornata.

Artemis II Mission Day 9 Recap April 9
By Burt Dicht NSS Space Coast Correspondent THE FINAL FULL DAY IN SPACE Flight Day 9 – Almost Home On their last full day in space, the Artemis II crew began the morning with “Lonesome Drifter” by Charley Crockett, approaching Earth at 147,337 miles. By midday, Orion was traveling at 2,808 mph — a speed that will continue building rapidly as Earth’s gravitational pull strengthens. OVERNIGHT UPDATE — SECOND RETURN TRAJECTORY BURN Orion’s thrusters ignited for the second return trajectory correction burn at 10:53 p.m. EDT Thursday, fine-tuning the spacecraft’s path toward Earth. The burn went smoothly and Integrity remains precisely on course for Friday’s splashdown. A third and final correction burn is scheduled for today at 1:53 p.m. EDT if needed. PACKING UP FOR HOME The crew spent the day preparing the cabin and studying entry procedures ahead of splashdown, stowing equipment and installing their seats to ensure all items are secured for reentry. After 10 days in deep space, the small cabin of Integrity is being methodically transformed from a living and working environment into a tightly secured reentry configuration. THE HEAT SHIELD — THE FINAL TEST During the only previous Orion test flight to the Moon the uncrewed Artemis I in 2022 — the heat shield suffered more damage than expected, prompting NASA to modify the reentry trajectory specifically to reduce stress on the shield for Artemis II. Engineers completed a final inspection of the crew module’s surface in the days before reentry and reported no concerns and no issues that would impact the return. NASA’s Lakiesha Hawkins acknowledged the weight of the moment plainly: “We’re down to the wire now. We’re down to the end of the mission, and obviously getting the crew back home and getting them landed safely is a significant part of the risk that’s still in front of us.” Flight Director Rick Henfling echoed that with confidence in the engineering work done: “I have a lot of confidence in the engineering that was done and the testing that was done. When I sit console on entry day, the heat shield is not going to be something that I’m thinking about.” Today’s reentry will be the definitive real-world test — and NASA goes into it with every reason for confidence. RECOVERY FORCES IN POSITION The USS John P. Murtha is now on station in the Pacific Ocean off the coast of San Diego, leading recovery efforts. Navy MH-60 Seahawk helicopters from Helicopter Sea Combat Squadron 23 have arrived on the ship’s flight deck and are conducting final air operations training ahead of Friday’s recovery. Flight Director Jeff Radigan explained what happens immediately after splashdown: “There are a number of systems that we have to begin an orderly shutdown, and the crew has to orient themselves and begin ‘safing’ the spacecraft so they can open the hatch, and that takes a little bit of time.” He added that recovery forces will work in parallel to ensure no one is hit by falling debris from reentry. WEATHER — STILL LOOKING GOOD The weather forecast remains favorable for the splashdown site within 100 miles of the coast of San Diego, with the majority of weather criteria in order for a safe recovery mission both by sea and by air. UNDERSTANDING ORION’S “OXIDIZER ISSUE” One of the questions I have been hearing repeatedly and one that NASA has now addressed several times in its press briefings — concerns the so-called “oxidizer issue.” Given how alarming that phrase can sound, especially to those worried about the crew’s safety, it is important to explain exactly what NASA is referring to. For many people, hearing a term that sounds like “oxygen” immediately raises fears that the astronauts could be in danger. NASA has been careful to clarify that this is not a life-support issue and has nothing to do with the crew’s breathing oxygen supply inside the cabin. Instead, this is a propulsion system issue involving a minor helium leak in the pressurization system associated with the oxidizer side of Orion’s propulsion system. The service module uses a hypergolic propulsion system, in which fuel and oxidizer are stored separately and fed to the engine and thrusters under pressure. Helium provides that pressure, ensuring that the propellants flow properly during major maneuvers and attitude control firings. According to NASA, the leak is small, stable, and well within operational margins, which is why the agency’s response has remained consistent throughout multiple press conferences. Most importantly, the spacecraft has already successfully completed its major burns, including the translunar injection and the lunar flyby trajectory maneuvers, demonstrating that the propulsion system has continued to perform as required. That said, this is not an issue NASA will simply dismiss. Because Orion’s service module is intentionally jettisoned prior to reentry and burns up in Earth’s atmosphere, the hardware will not be available for postflight inspection. Before Artemis III, NASA and the European Space Agency will need to fully understand the root cause of the leak using telemetry and engineering data and develop any required corrective actions. This is exactly why Artemis II is such an important test flight: it allows engineers to uncover issues in an operational deep-space environment and address them before Orion carries astronauts toward a lunar landing. FLIGHT DAY 10 PREVIEW — SPLASHDOWN DAY Friday, April 10, 2026 Everything now points to this evening’s splashdown which is targeted for 8:07 p.m. EDT (5:07 p.m. PDT) off the coast of San Diego. NASA Live coverage begins at 6:30 p.m. EDT on NASA+, Amazon Prime, Apple TV, Netflix, HBO Max, Discovery+, Peacock, and Roku. The 13-minute reentry sequence — from atmospheric entry to splashdown — will be the most physically intense phase of the entire mission, with the crew experiencing up to 3.9 Gs and a six-minute communications blackout as plasma engulfs the capsule. TIMELINE OF KEY EVENTS (ALL TIMES EDT) 6:30 p.m. — Live return coverage begins on NASA+, Amazon Prime, Apple TV, Netflix, HBO Max, Discovery+, Peacock, and Roku. ~7:25 p.m. — The crew configures the capsule’s cabin for reentry, stowing baggage and ensuring everything is ready for the reentry. ~7:37 p.m. — Orion performs a final quick burn to maneuver into the correct position and attitude for reentry and splashdown . ~7:25 p.m. — The service module — which has provided power and propulsion throughout the mission — separates from the crew module and burns up in the atmosphere. 7:53 p.m. — As Orion descends through about 400,000 feet, the spacecraft enters a planned six-minute communications blackout as plasma forms around the capsule during peak heating. The Fiery Plunge — 13 Minutes That Have to Go Right “It’s 13 minutes of things that have to go right,” said NASA Flight Director Jeff Radigan during the final mission status briefing. In his own mind, he added, it’s more like “an hour and a half of things that have to go right.” The Orion capsule will hit the atmosphere at a predicted 23,840 mph — mind-bogglingly fast, and hot enough to create temperatures of 5,000 degrees Fahrenheit on the heat shield’s surface. Together, the friction and compression of the atmosphere create a plasma bubble that engulfs the spacecraft and it’s that plasma that blocks all radio signals in and out. Retired NASA astronaut Barry “Butch” Wilmore put it plainly: “Everything’s different. The speeds are much, much greater coming back from deep space.” The Parachute Sequence After emerging from the blackout, Orion will jettison its forward bay cover, deploy its drogue parachutes near 22,000 feet at 8:03 p.m., and then unfurl its three main parachutes around 6,000 feet at 8:04 p.m. to slow the capsule for splashdown. By the time Orion hits the water, the parachutes will have slowed it to a far safer 20 mph. Splashdown — 8:07 p.m. EDT Splashdown is targeted for 8:07 p.m. in the Pacific Ocean just off the coast of San Diego. During the 13-minute descent, the crew will have effectively traversed 1,701 nautical miles. Based on the planned trajectory, the spacecraft will not be visible to those on the California coast, as it will be targeting a landing area well offshore. Recovery — USS John P. Murtha Within two hours after splashdown, the crew will be extracted from Orion and flown to the USS John P. Murtha by helicopter. Once aboard, the astronauts will undergo post-mission medical evaluations in the ship’s medical bay before returning to shore and boarding an aircraft bound for NASA’s Johnson Space Center in Houston. Flight Director Radigan expects the four astronauts to arrive in Houston on Saturday, where they will reunite with their families and loved ones.
