Introducing SharedRoot vulnerability: we recently found and reported several sandbox escape vulnerabilities to @AnthropicAI, and today we want to share one of these. I think most people don't understand the severity of the situation we are facing, with AI-assisted kernel bug-finding industrializing. Sandboxes are structurally one N-day behind, all the time, so containment can't lean on a guest Linux kernel being clean. SharedRoot enables escaping the Cowork VM (a kernel-level isolated solution, which is considered much more secure than the sandbox that ships with codex or claude code), allowing an attacker to gain unauthorized access to the user’s computer. Exploiting the SharedRoot vulnerability uncovered by the @Accomplish_ai research team, a user who is certain Cowork only has access to a specific uploaded folder on their computer - actually exposes their entire contents of their computer to an attacker leveraging the Cowork vulnerability. Read about the full technical details of the attack chain in our blog post by @orenyomtov below -->
we had a significant security incident during evaluation of our models. we are sharing what we have learned so far. thanks to @huggingface for the partnership on this. openai.com/index/hugging-…

Agentic loops are stubborn, which is why agents are effective. However, in hardened enterprise environments, things start to break. How do they break, and how can you steer the agent's pivoting behavior the right way? Some findings from our research, Fable/Mythos included! 👾
A question that sounds simple and isn't: what does a capable agent actually do when an enterprise security policy tells it 'no'? 480 workflows later - Haiku through Opus and our Fable/Mythos work included - the short answer is that it pivots, and steering that pivot well is one of the more underrated problems in deploying agents safely. We did it with kernel-level primitives rather than skills, for reasons worth reading about: determinism, invisibility, and a clean context. Findings in the thread.

@_orcaman פירות ים וויסקי, שתי אהובות גדולות 😋 נשמע מעולה!
אם אתם או חברים שלכם (או יותר טוב, חברות) עובדים / מכירים חבר׳ה מ-AI21 ו/או מטא שהושפעו מהפיטורים האחרונים, אשמח לשמוע מכם. אנחנו בונים משהו גדול ב-AI פה בשרונה ומחפשים מהנדסים סופר חזקים (סיניורים בלבד). בקבוק וויסקי משובח ביותר למי שיפנה מועמד.ת שיתקבל
@GalElmalah @_orcaman @grok Zara asked me to write you: "My path is long, and no one has ever trodden it to the end; it is a path that leads towards my own sun, and I know that I am just a beginner, just one who is learning to walk, one who is learning to be." — Nietzsche, Also sprach Zarathustra
Ever since I started using AI in its most popular interface, chat, it has bothered me that there's no way to visually point things out to it, everything has to be explained in words. Some tried solving this with mentioning features, but this right here is spot on, or more like - point on.
We’re reimagining a 50-year-old interface - the mouse pointer - with AI. 🖱️ These experimental demos show how people can intuitively direct Gemini on their screens using motion, speech, and natural shorthand to get things done 🧵

מכירים את זה שמצרפים אתכם לקבוצת ווטסאפ גדולה ולא שאלו לרשותכם? בטח זה קרה לכם יותר מפעם אחת… ב-7.10.23 בסביבות השעה 7:15 צירפו אותי בעל כורחי לקבוצה שלא ביקשתי להצטרף אליה - קבוצת ״משפחת השכול״. כבר יש לי מספיק קבוצות, תודה. לא מעוניין. אבל אף אחד לא שאל. באותו היום כמה עשרות אלפים הצטרפו אליה, וגם אני - כי אח שלי עומר ז״ל נרצח. זו קבוצה שכל כמה זמן מתעוררת - אם זה מהודעה מביטוח לאומי שמתחילה ב״משפחות יקרות…״, או מ״הודעות כפר עזה״, או פשוט בגלל זכרון ילדות או סתם געגוע. וביום הזה במיוחד היא מאוד פעילה כי כולנו קיבלנו תזכורת, תייגו את כולנו. זו קבוצה מיוחדת ״משפחת השכול״, כי אי אפשר לעשות לה ״השתק״, פשוט צריך ללמוד לחיות איתה. פשוט, לא באמת, במיוחד לא היום. אוהב ומתגעגע אליך אח יקר ❤️
יש לי PC גיימינג סבבה אבל ישן. מריץ את 2 המשחקים העיקריים שלי (אוברווטש/פורטנייט) ב-FPS נמוך. לפני כמה ימים ביקשתי מ- @Accomplish_ai "היי אחי, תעשה שהמשחקים ירוצו יותר מהר בלי לשבור יותר מדי דברים. SSD ב-C: והאחר HDD". הרווחתי עוד 40 FPS והמח התפוצץ. cc:@_orcaman
