Ein verantwortungsvoller und koordinierter Umgang mit Schwachstellen hat sich bewährt, sowohl für Unternehmen als auch für Security-Researcher und Ethical Hacker. Das NCSC hat einen Leitfaden publiziert: Eine Übersicht und Einstiegshilfe zugleich.

Git open source software is often used in software development. Insufficiently protected .git folders are a major security risk – also in Switzerland. The NCSC has informed affected website operators. ncsc.admin.ch/git-en

The first bug bounty program on the Federal Administration's central platform has taken place. It involved testing the Federal Administration's central access system, eIAM. Ethical hackers can sign up for future bug bounty programs. ncsc.admin.ch/ncsc/en/home/a…
Der Bund beschafft eine Plattform für Bug Bounty-Programme. Künftig werden ethische Hacker im Auftrag des NCSC und in Zusammenarbeit mit @bugbounty_ch die IT-Systeme der Bundesverwaltung nach Schwachstellen durchsuchen. ncsc.admin.ch/bb-2022-de
Today @kavehrazavi and I are finally allowed to talk about #Retbleed. In 2018, #SpectreV2 was fixed by replacing indirect jumps with returns. But, returns can be poisoned like indirect jumps, throwing us us back to 2018 again. Paper, demo, addendum, code @ comsec.ethz.ch/retbleed
⚠️ Attention ⚠️ Cybercriminals are currently sending out fake emails in the name of the NCSC. For this purpose, the threat actors are using the domain ncscS .ch (additional S). Do not reply to such emails! 🛑📧
Heads up: We see a lot of scanning against the #log4j vulnerability and decided to publish a blog post with some guidance: govcert.ch/blog/zero-day-… Please patch now!
