Up until now, as people experiment with Agentic AI and tool support, they’ve mostly adopted the MCP stdio transport, which means you end up with a 1:1 deployment of MCP server and MCP client. What organizations need is a way to deploy MCP servers remotely and leverage authorization to give resource owner’s access to their data safely. --------------------------------------------- https://blog.christianposta.com/the-updated-mcp-oauth-spec-is-a-mess/ ∗∗∗ Practical Cyber Deception — Introduction to “Chaotic Good” ∗∗∗ --------------------------------------------- Cyber deception isn’t about building expensive honeynets or deploying complex traps — it’s about instilling doubt and confusion in the attacker. By layering practical, tactical deception into your environment, you shift the balance of power: slowing them down, forcing mistakes, and gaining early warning long before real damage is done. From fake servers and canary tokens to ransomware drive traps, deception turns defense from a reactive grind into a strategic, active game. --------------------------------------------- https://detect.fyi/practical-cyber-deception-introduction-to-chaotic-good-2… ∗∗∗ Phishers Take Advantage of Iberian Blackout Before Its Even Over ∗∗∗ --------------------------------------------- Opportunistic threat actors targeted Portuguese and Spanish speakers by spoofing Portugals national airline in a campaign offering compensation for delayed or disrupted flights. --------------------------------------------- https://www.darkreading.com/cyberattacks-data-breaches/phishers-take-advant… ===================== = Vulnerabilities = ===================== ∗∗∗ Dell schützt PowerProtect Data Manager und Laptops vor möglichen Attacken ∗∗∗ --------------------------------------------- In einer Warnmeldung führen die Entwickler aus, dass PowerProtect Data Manager über mehrere Lücken in Komponenten von Drittanbietern wie Golang und Spring Framework, aber auch über Lücken in der Anwendung selbst angreifbar ist. Sind Attacken erfolgreich, können sich Angreifer etwa mit lokalem Zugriff und niedrigen Rechten höhere Nutzerrechte verschaffen (CVE-2025-23375 "hoch").

===================== = End-of-Day report = ===================== Timeframe: Freitag 18-04-2025 18:00 − Dienstag 22-04-2025 18:00 Handler: Michael Schlagenhaufer Co-Handler: Felician Fuchs ===================== = News = ===================== ∗∗∗ DOGE, CISA, Mitre und CVE ∗∗∗ --------------------------------------------- In der Cybersecurity Community herrschte letzte Woche helle Aufregung, weil die Einsparungstruppe von Trumps Gnaden die grandiose Idee hatte, das Funding für den Betrieb des CVE-Systems durch Mitre einzustellen. Wahrscheinlich aufgrund des starken Gegenwindes von der Seite der US-Industrie wurde eine Lösung gefunden und der Betrieb ist (angeblich) für die nächsten 11 Monate gesichert. Ich will das zum Anlass nehmen, das System hinter den bekannten CVE-Nummern zu erklären und mögliche Entwicklungen aufzuzeigen. --------------------------------------------- https://www.cert.at/de/blog/2025/4/doge-cisa-mitre-und-cve ∗∗∗ Phishers abuse Google OAuth to spoof Google in DKIM replay attack ∗∗∗ --------------------------------------------- In a rather clever attack, hackers leveraged a weakness that allowed them to send a fake email that seemed delivered from Googles systems, passing all verifications but pointing to a fraudulent page that collected logins. --------------------------------------------- https://www.bleepingcomputer.com/news/security/phishers-abuse-google-oauth-… ∗∗∗ Phishing attacks leveraging HTML code inside SVG files ∗∗∗ --------------------------------------------- The SVG format provides the capability to embed HTML and JavaScript code within images, which is misused by attackers. Despite not being widespread at the time of this study, SVG attachment attacks are showing a clear upward trend. --------------------------------------------- https://securelist.com/svg-phishing/116256/ ∗∗∗ Videokameras: Schwere Sicherheitslücke bei Überwachungsgeräten der Polizei ∗∗∗ --------------------------------------------- Polizeibehörden in zahlreichen Ländern nutzen mobile Sender der Firma Infodraw. Doch die hochgeladenen Daten sind nicht ausreichend gesichert. [..] Über das Bundesamt für Sicherheit in der Informationstechnik (BSI) wurden laut Schäfers inzwischen in Deutschland alle übrigen Betreiber gewarnt. [..] Ihm zufolge reicht es nicht aus, die aktuelle Softwareversion 7.1.0.0 installiert zu haben. Wobei aktuell relativ ist, denn die Version stammt aus dem Jahr 2000. Schäfers empfiehlt den nutzenden Organisationen, die Anwendung unmittelbar offline zu nehmen. --------------------------------------------- https://www.golem.de/news/videokameras-schwere-sicherheitsluecke-bei-ueberw… ∗∗∗ Agent In the Middle – Abusing Agent Cards in the Agent-2-Agent (A2A) Protocol To ‘Win’ All the Tasks ∗∗∗ --------------------------------------------- I’ll write a blog post on prompt injection defenses and how I am able to circumvent them another time… the blog post today is about one of those advancements: the Agent-2-Agent (A2A) Protocol. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/agent-in-th… ∗∗∗ Microsoft Secures MSA Signing with Azure Confidential VMs Following Storm-0558 Breach ∗∗∗ --------------------------------------------- Microsoft on Monday announced that it has moved the Microsoft Account (MSA) signing service to Azure confidential virtual machines (VMs) and that it's also in the process of migrating the Entra ID signing service as well. The disclosure comes about seven months after the tech giant said it completed updates to Microsoft Entra ID and MS for both public and United States government clouds to generate, store, and automatically rotate access token signing keys using the Azure Managed Hardware Security Module (HSM) service. --------------------------------------------- https://thehackernews.com/2025/04/microsoft-secures-msa-signing-with.html ∗∗∗ Anspruch auf Kostenerstattung? Vorsicht vor neuer ÖGK-Betrugsmasche ∗∗∗ --------------------------------------------- Neue Website, alte Masche. Kriminelle haben eine weitere Betrugswelle im Namen der Österreichischen Gesundheitskasse gestartet. Sie locken mit einer hohen Rückzahlung und setzen auf eine beinahe 1:1-Kopie der originalen ÖGK-Website. So können Sie den Fake dennoch erkennen. --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-neue-oegk-betrugsmasche/ ∗∗∗ Ivanti Endpoint Manager_Local Privilege Escalation via DLL Search Order Hijacking ∗∗∗ --------------------------------------------- The Ivanti Endpoint Manager Security Scan (Vulscan) Self Update was vulnerable to DLL Hijacking. 2025-04-08 Vendor publishes security advisory. 2025-04-22 Coordinated disclosure of security advisory. CVE Number CVE-2025-22458 --------------------------------------------- https://sec-consult.com/de/vulnerability-lab/advisory/mehrere-schwachstelle… ∗∗∗ Microsoft’s patch for CVE-2025–21204 symlink vulnerability introduces another symlink vulnerability ∗∗∗ --------------------------------------------- Microsoft recently patched CVE-2025–21204, a vuln which allows users to abuse symlinks to elevate privileges using the Windows servicing stack and the c:\inetpub folder. [..] However, I’ve discovered this fix introduces a denial of service vulnerability in the Windows servicing stack that allows non-admin users to stop all future Windows security updates. [..] I reported this to MSRC about two weeks ago, but haven’t had a response. --------------------------------------------- https://doublepulsar.com/microsofts-patch-for-cve-2025-21204-symlink-vulner… ∗∗∗ Zugangs- und Schließsysteme mit Internetanbindung als Risiko – Teil 1 ∗∗∗ --------------------------------------------- Heute noch ein kleiner, zweiteiliger Sammelbeitrag, in dem ich auf die Risiken eingehe, welche Schließsysteme bzw. Systeme zur Zugangskontrolle sowie zur Zeiterfassung unter Umständen bieten. --------------------------------------------- https://www.borncity.com/blog/2025/04/20/risiko-zeiterfassungs-zugangs-und-… ∗∗∗ Systeme zur Zeiterfassung mit Internetanbindung als Risiko – Teil 2 ∗∗∗ --------------------------------------------- In Teil 1 des zweiteiligen Sammelbeitrags hatte ich auf die Risiken hingewiesen, die von elektronischen Schließsystemen bzw. Systemen zur Zugangskontrolle ausgehen können, wenn diese am Internet hängen. Aber auch Systeme zur Zeiterfassung, die per Internet erreichbar sind, fallen in diese Kategorie, sofern Dienstleister diese allzu sorglos eingerichtet haben. --------------------------------------------- https://www.borncity.com/blog/2025/04/21/systeme-zur-zeiterfassung-mit-inte… ===================== = Vulnerabilities = ===================== ∗∗∗ Asus-Router: Sicherheitslücke ermöglicht unbefugtes Ausführen von Funktionen ∗∗∗ --------------------------------------------- Im CVE-Eintrag zur Schwachstelle erörtert Asus, dass in der AiCloud eine unzureichende Authentifizierungskontrolle stattfinde. Diese lasse sich durch manipulierte Anfragen missbrauchen, um ohne Autorisierung Funktionen auszuführen (CVE-2025-2492, CVSS 9.2, Risiko "kritisch"). [..] In der Sicherheitsmitteilung schreibt Asus lediglich, dass die Entwickler aktualisierte Firmware für die Serien 3.0.0.4_382, 3.0.0.4_386, 3.0.0.4_388 und 3.0.0.6_102 veröffentlicht hat. Die soll die Schwachstelle ausbessern. --------------------------------------------- https://www.heise.de/news/Asus-Router-Sicherheitsluecke-ermoeglicht-unbefug… ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (erlang, fig2dev, shadow, wget, and zabbix), Fedora (chromium, jupyterlab, llama-cpp, prometheus-podman-exporter, python-notebook, python-pydantic-core, rpki-client, rust-adblock, rust-cookie_store, rust-gitui, rust-gstreamer, rust-icu_collections, rust-icu_locid, rust-icu_locid_transform, rust-icu_locid_transform_data, rust-icu_normalizer, rust-icu_normalizer_data, rust-icu_properties, rust-icu_properties_data, rust-icu_provider, rust-icu_provider_macros, rust-idna, rust-idna_adapter, rust-litemap, rust-ron, rust-sequoia-openpgp, rust-sequoia-openpgp1, rust-tinystr, rust-url, rust-utf16_iter, rust-version-ranges, rust-write16, rust-writeable, rust-zerovec, rust-zip, uv, and webkitgtk), Slackware (libxml2 and zsh), SUSE (argocd-cli, chromium, coredns, ffmpeg-6, and firefox), and Ubuntu (imagemagick). --------------------------------------------- https://lwn.net/Articles/1018292/ ∗∗∗ Security updates for Tuesday ∗∗∗ --------------------------------------------- Security updates have been issued by AlmaLinux (java-1.8.0-openjdk, kernel, libxslt, mod_auth_openidc:2.3, and webkit2gtk3), Fedora (c-ares, giflib, jupyterlab, perl, perl-Devel-Cover, perl-PAR-Packer, prometheus-podman-exporter, python-notebook, python-pydantic-core, rpki-client, ruby, rust-adblock, rust-cookie_store, rust-gitui, rust-gstreamer, rust-icu_collections, rust-icu_locid, rust-icu_locid_transform, rust-icu_locid_transform_data, rust-icu_normalizer, rust-icu_normalizer_data, rust-icu_properties, rust-icu_properties_data, rust-icu_provider, rust-icu_provider_macros, rust-idna, rust-idna_adapter, rust-litemap, rust-ron, rust-sequoia-openpgp, rust-sequoia-openpgp1, rust-tinystr, rust-url, rust-utf16_iter, rust-version-ranges, rust-write16, rust-writeable, rust-zerovec, rust-zip, thunderbird, and uv), SUSE (erlang, erlang26, and govulncheck-vulndb), and Ubuntu (mosquitto). --------------------------------------------- https://lwn.net/Articles/1018444/ ∗∗∗ Zyxel security advisory for incorrect permission assignment and improper privilege management vulnerabilities in USG FLEX H series firewalls ∗∗∗ --------------------------------------------- https://www.zyxel.com/global/en/support/security-advisories/zyxel-security-… ∗∗∗ Wordpress: Angreifer können über Greenshift-Plug-in Schadcode hochladen ∗∗∗ --------------------------------------------- https://heise.de/-10357624 ∗∗∗ SicommNet BASEC product warning ∗∗∗ --------------------------------------------- https://csirt.divd.nl/2025/04/14/SicommNet-Basec-product-warning/ ∗∗∗ Tenable: [R1] Stand-alone Security Patch Available for Tenable Security Center version 6.5.1: SC-202504.3 ∗∗∗ --------------------------------------------- https://www.tenable.com/security/tns-2025-06 -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily
