Vasileios Kemerlis📢 Honored to return to Yale University last week to speak at the Department of Computer Science colloquium on Operating Systems security -- exactly 10 years after my first talk there on the same topic!In this "tin anniversary" edition, I reflected on how OS kernel exploitation and defense have evolved over the past decade, and shared highlights from some of our recent work in the field over the last five years:✳️ xMP (IEEE S&P 2020: 📄 <a href="https://cs.brown.edu/~vpk/papers/xmp.sp20.pdf" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://cs.brown.edu/~vpk/papers/xmp.sp20.pdf</a>, 💾 <a href="https://github.com/virtsec/xmp" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/virtsec/xmp</a>) — Selective intra-kernel memory isolation using hardware-assisted virtualization.✳️ SafeSLAB (ACM CCS 2024: 📄 <a href="https://cs.brown.edu/~vpk/papers/safeslab.ccs24.pdf" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://cs.brown.edu/~vpk/papers/safeslab.ccs24.pdf</a>, 💾 <a href="https://github.com/tum-itsec/safeslab" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/tum-itsec/safeslab</a>) — Kernel heap hardening through memory tagging.✳️ EPF (USENIX ATC 2023: 📄 <a href="https://cs.brown.edu/~vpk/papers/epf.atc23.pdf" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://cs.brown.edu/~vpk/papers/epf.atc23.pdf</a>, 💾 <a href="https://gitlab.com/brown-ssl/epf" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://gitlab.com/brown-ssl/epf</a>) — Exploiting the (e)BPF sub-system for bypassing modern protections and ways to fix this.(Joint work with <a href="https://infosec.exchange/@mikepo" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@mikepo</a>, Marius Momeu, Vaggelis Atlidakis, <a href="https://mastodon.social/@dijin" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@dijin</a>, and Sergej Proskurin.)If this area of research interests you, you might also find our recent work on BeeBox (strengthening eBPF against transient execution attacks, USENIX Security 2024: 📄 <a href="https://cs.brown.edu/~vpk/papers/beebox.sec24.pdf" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://cs.brown.edu/~vpk/papers/beebox.sec24.pdf</a>, 💾 <a href="https://gitlab.com/brown-ssl/beebox" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://gitlab.com/brown-ssl/beebox</a>) and IUBIK (leveraging memory tagging and pointer authentication to isolate attacker-controlled data in kernel space, to appear in IEEE S&P 2025) worth a look.It was a real pleasure catching up with friends, colleagues, and students. And with the spring weather fully cooperating, I couldn't resist snapping a few photos of Yale's beautiful campus in the early morning light.Thank you to my host Charalampos Papamanthou and the Yale CS department for the warm welcome and thoughtful discussion!<a href="https://infosec.exchange/tags/xmp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#xmp</a> <a href="https://infosec.exchange/tags/safeslab" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#safeslab</a> <a href="https://infosec.exchange/tags/epf" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#epf</a> <a href="https://infosec.exchange/tags/brownssl" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#brownssl</a>

utzer [Pleroma]Ich bin überzeugt: Fotoverwaltungssoftware sollte Metadaten immer direkt in den Bilddateien speichern – plattform- und softwareübergreifend nutzbar. Ob Gesichterkennung, Beschreibungstext, Kategorien oder manuelle Tags – all diese Infos gehören nicht nur in eine Datenbank, sondern auch als Metadaten direkt ins <a class="hashtag" href="https://soc.utzer.de/tag/bild" rel="nofollow noopener noreferrer" target="_blank">#Bild</a> (EXIF/XMP/IPTC etc.). Ich habe im Laufe der Jahre zwei Programme intensiver genutzt: Damals unter Windows: <a class="hashtag" href="https://soc.utzer.de/tag/picasa" rel="nofollow noopener noreferrer" target="_blank">#Picasa</a> (RIP). Heute unter Linux: <a class="hashtag" href="https://soc.utzer.de/tag/digikam" rel="nofollow noopener noreferrer" target="_blank">#Digikam</a>. Jetzt überlege ich, auf eine serverbasierte Lösung umzusteigen – aber immer bleibt dieselbe Frage: Wie <a class="hashtag" href="https://soc.utzer.de/tag/portabel" rel="nofollow noopener noreferrer" target="_blank">#portabel</a> sind meine Daten, wenn die Software ausfällt oder ich wechseln will? Eine Metadatenstrategie, die auf offene Standards setzt, erleichtert Backups, Migration, parallele Nutzung und langfristige Verfügbarkeit.

David SchmidtMoved over from Lightroom Classic to Lightroom. Kinda forced, since Lightroom Classic doesn't run on my new laptop with its Snapdragon CPU (ARM).First, I was slightly upset about me not knowing beforehand, now though, after playing around a little bit, I feel I can make the jump. Lightroom seems modern and lighter in processing. Also I like the idea of not being dependent on a proprietary catalog file.<a href="https://mastodon.social/tags/adobe" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#adobe</a> <a href="https://mastodon.social/tags/lightroom" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lightroom</a> <a href="https://mastodon.social/tags/lightroomclassic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lightroomclassic</a> <a href="https://mastodon.social/tags/xmp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#xmp</a> <a href="https://mastodon.social/tags/sidecar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sidecar</a> <a href="https://mastodon.social/tags/photoediting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photoediting</a> <a href="https://mastodon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://mastodon.social/tags/door" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#door</a> <a href="https://mastodon.social/tags/hamburg" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hamburg</a>
