The discussions have ranged from buying new sophisticated tools, auditing the development pipeline, to diffing patches. But really, for me it's as simple as saying "should my application server really be able to connect to any internet host on any protocol". --------------------------------------------- https://isc.sans.edu/diary/rss/27054 ∗∗∗ Hintermänner der Fonix-Ransomware geben auf und veröffentlichen Master-Schlüssel ∗∗∗ --------------------------------------------- Opfer des Verschlüsselungstrojaner Fonix sehen Licht am Ende des Tunnels. --------------------------------------------- https://heise.de/-5041914 ∗∗∗ SonicWall zero-day exploited in the wild ∗∗∗ --------------------------------------------- Security firm NCC Group said it detected "indiscriminate" exploitation of a mysterious SonicWall zero-day. --------------------------------------------- https://www.zdnet.com/article/sonicwall-zero-day-exploited-in-the-wild/ ∗∗∗ Shodan Verified Vulns 2021-02-01 ∗∗∗ --------------------------------------------- Wieder ist ein Monat vergangen und damit auch wieder die Zeit gekommen, um einen Blick auf Shodans Daten zu den Verified Vulnerabilities in Österreich zu werfen. --------------------------------------------- https://cert.at/de/aktuelles/2021/2/shodan-verified-vulns-2021-02-01 ∗∗∗ Trickbot feiert Comeback ∗∗∗ --------------------------------------------- Kaum ist die Freude über die Zerschlagung von Emotet verklungen, feiert ein anderes Malware-Netzwerk namens Trickbot nach einigen Monaten Stille ein Comeback. --------------------------------------------- https://www.zdnet.de/88393163/trickbot-feiert-comeback/ ===================== = Vulnerabilities = ===================== ∗∗∗ Sudo Privilege Escalation Vulnerability Affecting Cisco Products: January 2021 ∗∗∗ --------------------------------------------- A vulnerability in the command line parameter parsing code of Sudo could allow an authenticated, local attacker to execute commands or binaries with root privileges.

Of particular interest is the following note: “We do not believe that [the exploit] works against iOS 14 and above, which includes new security protections''. Given that it is also now almost exactly one year ago since we published the Remote iPhone Exploitation blog post series, in which we described how an iMessage 0-click exploit can work in practice and gave a number of suggestions on how similar attacks could be prevented in the future, now seemed like a great time to dig into the security improvements in iOS 14 in more detail and explore how Apple has hardened their platform against 0-click attacks. --------------------------------------------- https://googleprojectzero.blogspot.com/2021/01/a-look-at-imessage-in-ios-14… ∗∗∗ Sensitive Data Shared with Cloud Services, (Fri, Jan 29th) ∗∗∗ --------------------------------------------- Yesterday was the data protection day in Europe. I was not on duty so Im writing this quick diary a bit late. Back in 2020, the Nitro PDF service suffered from a data breach that impacted many companies around the world.

Das macht sich auch im Bereich des Internetbetrugs bemerkbar. So melden unsere LeserInnen immer wieder, dass sie bei der Suche nach einem Nebenverdienst auf ein betrügerisches Job-Angebot gestoßen sind. Das Ziel hinter dieser Betrugsmasche: Die BetrügerInnen versuchen die Identität der Opfer zu klauen, manchmal wird auch ein Konto im Namen der Betroffenen eröffnet. --------------------------------------------- https://www.watchlist-internet.at/news/identitaetsdiebstahl-durch-betrueger… ∗∗∗ Don’t stop at alert(1): Demonstrate impact with low severity bugs ∗∗∗ --------------------------------------------- When trying to discover vulnerabilities in a web application, you may not always come across high or critical severity bugs, and only end up finding low-medium severity issues like cross-site scripting (XSS). When that is the case, it is worth seeing how far those bugs can take you, since low severity vulnerabilities can still have a large effect when leveraged as part of a more impactful attack chain. --------------------------------------------- https://medium.com/tenable-techblog/dont-stop-at-alert-1-demonstrate-impact… ===================== = Vulnerabilities = ===================== ∗∗∗ Libgcrypt: Warnung vor schwerem Fehler in GnuPG-Kryptobibliothek ∗∗∗ --------------------------------------------- Die jüngste Version der Verschlüsselungsbibliothek Libgcrypt, die unter anderem von GnuPG verwendet wird, soll eine schwere Sicherheitslücke haben. --------------------------------------------- https://www.golem.de/news/libgcrypt-warnung-vor-schwerem-fehler-in-gnupg-kr… ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Arch Linux (dnsmasq, erlang, flatpak, go, gobby, gptfdisk, jenkins, kernel, linux-hardened, linux-lts, linux-zen, lldpd, openvswitch, podofo, virtualbox, and vlc), Fedora (erlang, firefox, nss, and seamonkey), Gentoo (imagemagick, nsd, and vlc), openSUSE (chromium and python-autobahn), Oracle (firefox and thunderbird), Red Hat (thunderbird), Scientific Linux (thunderbird), SUSE (firefox, jackson-databind, and thunderbird), and Ubuntu (libxstream-java). --------------------------------------------- https://lwn.net/Articles/844521/ ∗∗∗ Rockwell Automation FactoryTalk Linx and FactoryTalk Services Platform ∗∗∗ --------------------------------------------- This advisory contains mitigations for Classic Buffer overflow, and Improper Check or Handling of Exceptional Conditions vulnerabilities in Rockwell Automations FactoryTalk Linx and FactoryTalk Services Platform software. --------------------------------------------- https://us-cert.cisa.gov/ics/advisories/icsa-21-028-01 ∗∗∗ SSA-520004: Telnet Authentication Vulnerability in SIMATIC HMI Comfort Panels ∗∗∗ --------------------------------------------- https://cert-portal.siemens.com/productcert/txt/ssa-520004.txt ∗∗∗ Linksys Router: Schwachstelle ermöglicht Ausführen von beliebigem Programmcode mit Administratorrechten ∗∗∗ --------------------------------------------- http://www.cert-bund.de/advisoryshort/CB-K21-0101 -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

In these documents we came across an interesting technique being used to execute shellcode from VBA without the use of common “suspicious” APIs, such as VirtualAlloc, WriteProcessMemory or CreateThread – which may be detected by end point protection solutions. Instead, the macro documents abuse “benign” Windows API features toachieve code-execution. --------------------------------------------- https://research.nccgroup.com/2021/01/23/rift-analysing-a-lazarus-shellcode… ∗∗∗ Firewall-Hersteller SonicWall untersucht mögliche Zero-Day-Lücken in Produkten ∗∗∗ --------------------------------------------- Angreifer haben bislang unbekannte Lücken in SonicWall-Produkten ausgenutzt, um ins System des Herstellers einzudringen. --------------------------------------------- https://heise.de/-5033933 ∗∗∗ Von niedrig bis kritisch: Schwachstellenbewertung mit CVSS ∗∗∗ --------------------------------------------- Das Common Vulnerability Scoring System hilft bei der Bewertung von Schwachstellen.
