In der E-Mail werden Sie über Ihre Steuerrückerstattung informiert und aufgefordert, die Transaktion zu genehmigen. Klicken Sie aber keinesfalls auf den Link, Sie landen auf einer gefälschten FinanzOnline-Website, die es Kriminellen ermöglicht, persönliche Daten sowie Kreditkartendaten abzugreifen! --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-betruegerisches-finanzonlin… ∗∗∗ Industrieanlagen mit OPC UA systematisch schlecht konfiguriert ∗∗∗ --------------------------------------------- Forscher des Fraunhofer FKIE und der RWTH Aachen haben das Internet nach Steuerungen auf Basis des Standards OPC UA durchsucht. 92% waren unsicher eingerichtet. --------------------------------------------- https://heise.de/-4939199 ∗∗∗ Sicherheitsupdate: Angreifer attackieren Microsofts Webbrowser Edge ∗∗∗ --------------------------------------------- Die Entwickler von Microsoft haben im Webbrowser Edge mehrere Sicherheitslücken geschlossen. --------------------------------------------- https://heise.de/-4940091 ∗∗∗ Malware Emotet versteckt sich hinter gefälschtem Upgrade für Microsoft Word ∗∗∗ --------------------------------------------- Eine neue Kampagne gaukelt Opfern vor, sie benötigen ein Upgrade mit neuen Funktionen für Microsoft Word. Tatsächlich sollen sie die Sicherheitsvorkehrungen zum Schutz vor gefährlichen Makros deaktivieren. Die schädlichen Dokumente verteilen die Hintermänner weiterhin per E-Mail. --------------------------------------------- https://www.zdnet.de/88389137/malware-emotet-versteckt-sich-hinter-gefaelsc… ∗∗∗ KashmirBlack: Botnet attackiert WordPress, Joomla und Drupal ∗∗∗ --------------------------------------------- Die Hintermänner nutzen bekannte Schwachstellen in CMS-Plattformen und Plug-ins.

These are one of the most fundamental aspects of website security, yet we too often see webmasters taking a lax approach to secure passwords. In fact, the online security provider TeamPassword found that last year the most commonly leaked password was 123456. That edges out some real gems including qwerty and the always-popular password. --------------------------------------------- https://blog.sucuri.net/2020/10/password-security-password-managers.html ∗∗∗ P.A.S. Fork v. 1.0 — A Web Shell Revival ∗∗∗ --------------------------------------------- A PHP shell containing multiple functions can easily consist of thousands of lines of code, so it’s no surprise that attackers often reuse the code from some of the most popular PHP web shells, like WSO or b374k. After all, if these popular (and readily available) PHP web shells do the job, there’s no need to code an entirely new tool. --------------------------------------------- https://blog.sucuri.net/2020/10/p-a-s-fork-v-1-0-a-web-shell-revival.html ===================== = Vulnerabilities = ===================== ∗∗∗ VU#760767: Macrium Reflect is vulnerable to privilege escalation due to OPENSSLDIR location ∗∗∗ --------------------------------------------- Overview Macrium Reflect contains a privilege escalation vulnerability due to the use of an OPENSSLDIR variable that specifies a location where an unprivileged Windows user can create files.

Our tool detects BEHAVIOURS". That was like 15 years ago. Fast forward to today, with many of the same vendors now selling "threat intelligence feeds" for good money, and the most frequent attributes pushed over these feeds are MD5/SHA1 hashes and IP addresses. The main thing that changed is that we now call these items [...] --------------------------------------------- https://isc.sans.edu/diary/rss/26624 ∗∗∗ Network Detection for ZeroLogon (CVE-2020-1472) ∗∗∗ --------------------------------------------- ZeroLogon has quickly become popular and well known because of multiple proofs of concept and exploits implemented in Python, .NET, Powershell, and Mimikatz implemented a module for it. So if you are an attacker or need to test your environment then you have plenty of options. As defenders, we also have options for detection on the network. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/network-det… ∗∗∗ Evasive URLs in Spam: Part 2 ∗∗∗ --------------------------------------------- A URL can be completely valid, yet still misleading.

Most of these incidents are the result of a phishing email coercing a user to enter their credentials used for accessing M365 into a phishing site. Other incidents have been a result of password spraying, password stuffing, or simple brute force attempts against M365 tenants. In almost all of these incidents, the user or account was not protected by multi-factor authentication (MFA). --------------------------------------------- http://www.fireeye.com/blog/threat-research/2020/09/detecting-microsoft-365… ∗∗∗ Three immediate steps to take to protect your APIs from security risks ∗∗∗ --------------------------------------------- In one form or another, APIs have been around for years, bringing the benefits of ease of use, efficiency and flexibility to the developer community. The advantage of using APIs for mobile and web apps is that developers can build and deploy functionality and data integrations quickly.

The flaws, discovered by Tel Aviv-based OTORIO, were identified in B&R Automations SiteManager and GateManager, and MB Connect [...] --------------------------------------------- https://thehackernews.com/2020/10/industrial-remote-access.html ∗∗∗ Sony IPELA Network Camera (ftpclient.cgi) Remote Stack Buffer Overflow ∗∗∗ --------------------------------------------- The vulnerability is caused due to a boundary error in the processing of received FTP traffic through the FTP client functionality (ftpclient.cgi), which can be exploited to cause a stack-based buffer overflow when a user issues a POST request to connect to a malicious FTP server. Successful exploitation could allow execution of arbitrary code on the affected device or cause denial of service scenario. --------------------------------------------- https://www.zeroscience.mk/en/vulnerabilities/ZSL-2020-5596.php ∗∗∗ Vulnerability Spotlight: Remote code execution bugs in NVIDIA D3D10 driver ∗∗∗ --------------------------------------------- Cisco Talos recently discovered multiple remote code execution vulnerabilities in the NVIDIA D3D10 driver. This driver supports multiple GPUs that NVIDIA produces. An adversary could exploit these vulnerabilities by supplying the user with a malformed shader, eventually allowing them to execute code on the victim machine. These bugs could also allow the attacker to perform a guest-to-host escape through Hyper-V [...] --------------------------------------------- https://blog.talosintelligence.com/2020/09/vuln-spotlight-nvidia-d3d10-.html ∗∗∗ Security updates for Thursday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (ruby-json-jwt and ruby-rack-cors), Fedora (xen), SUSE (aspell and tar), and Ubuntu (ruby-gon, ruby-kramdown, and ruby-rack). --------------------------------------------- https://lwn.net/Articles/833191/ ∗∗∗ Broken access control in Platinum Mobile ∗∗∗ --------------------------------------------- https://sec-consult.com/./en/blog/advisories/broken-access-control-in-plati… ∗∗∗ Red Hat OpenShift: Schwachstelle ermöglicht Umgehen von Sicherheitsvorkehrungen ∗∗∗ --------------------------------------------- http://www.cert-bund.de/advisoryshort/CB-K20-0946 ∗∗∗ Security Bulletin: Open Source Apache Tomcat vulnerabilities affect IBM Tivoli Application Dependency Discovery Manager (CVE-2020-13935) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-open-source-apache-tomcat… ∗∗∗ Security Bulletin: IBM Cloud Pak System is affected by a vulnerability in VMware component ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-cloud-pak-system-is-a… ∗∗∗ Security Bulletin: Vulnerability in IBM Java Runtime affect IBM Netcool Agile Service Manager ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-ibm-java… ∗∗∗ Security Bulletin: App Connect Enterprise Certified Container is affected by multiple Node.js vulnerabilities ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-app-connect-enterprise-ce… ∗∗∗ Security Bulletin: A vulnerability in Netty affects IBM Netcool Agile Service Manager ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-netty-… ∗∗∗ Security Bulletin: WebSphere Application Server is vulnerable to an information disclosure vulnerability (CVE-2020-4576) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-websphere-application-ser… ∗∗∗ Security Bulletin: Vulnerability in Apache Commons Codec Affects IBM Sterling Secure Proxy ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-apache-c… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

September 2020 kam es zu einem IT-Sicherheitsvorfall im Universitätsklinikum Düsseldorf (UKD). Gemäß BSI-Gesetz hat das UKD das Bundesamt für Sicherheit in der Informationstechnik (BSI) über diesen Vorfall informiert. [...] In diesem Zusammenhang weist das BSI mit Nachdruck darauf hin, dass derzeit eine seit Januar 2020 bekannte Schwachstelle (CVE-2019-19781) in VPN-Produkten der Firma Citrix für Cyber-Angriffe ausgenutzt wird. Dem BSI werden zunehmend Vorfälle bekannt, bei denen Citrix-Systeme bereits vor der Installation der im Januar 2020 bereitgestellten Sicherheitsupdates kompromittiert wurden. Dadurch haben Angreifer auch nach Schließung der Sicherheitslücke weiterhin Zugriff auf das System und dahinterliegende Netzwerke.
