===================== = End-of-Day report = ===================== Timeframe: Donnerstag 02-07-2020 18:00 − Freitag 03-07-2020 18:00 Handler: Dimitri Robl Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ Unternehmen aufgepasst: Versand gefährlicher Mails im Namen des Bundeskanzleramts ∗∗∗ --------------------------------------------- „Die Entscheidung, Ihr Unternehmen aufgrund von Covid-19 zu schließen“ – unter diesem Betreff werden derzeit betrügerische Mails verschickt, die sich gezielt an Unternehmerinnen und Unternehmer richten. Die Kriminellen, die hinter dieser E-Mail stehen, geben sich dabei als Bundeskanzleramt aus und verschicken Schadsoftware. Öffnen Sie daher auf keinen Fall den Anhang! --------------------------------------------- https://www.watchlist-internet.at/news/unternehmen-aufgepasst-versand-gefae… ∗∗∗ Ransomware EKANS nimmt Industriekontrollsysteme ins Visier ∗∗∗ --------------------------------------------- Die Schadsoftware funktioniert trotz zahlreicher Programmierfehler. Eine neue Variante verschlüsselt nicht nur Dateien, sie verändert auch die Einstellungen von Industriekontrollsystemen. EKANS ist zudem auf bestimmte Ziele ausgerichtet und greift Opfer nicht wahllos an. --------------------------------------------- https://www.zdnet.de/88381196/ransomware-ekans-nimmt-industriekontrollsyste… ∗∗∗ Still Scanning IP Addresses? You’re Doing it Wrong ∗∗∗ --------------------------------------------- The traditional approach to a vulnerability scan or penetration test is to find the IP addresses that you want tested, throw them in and kick things off. But doing a test based purely on IP addresses is a bad idea and can often miss things. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/still-scann… ∗∗∗ GoldenSpy Chapter 3: New and Improved Uninstaller ∗∗∗ --------------------------------------------- This blog shows our analysis of a new binary, now being distributed by Intelligent Tax software, that is identical in operations to the original GoldenSpy Uninstallers, but specifically designed to evade detection by the YARA rule provided in our blog. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/goldenspy-c… ∗∗∗ Dangerous Website Backups ∗∗∗ --------------------------------------------- It’s a well-known fact that website backups are important for mitigating a plethora of site issues. They can help restore a site after a compromise or even facilitate the investigative process by providing a clean code base to compare the current site state to. However, if a backup is not set up correctly, it can have the opposite effect — and may instead impose a security threat to your website. --------------------------------------------- https://blog.sucuri.net/2020/07/dangerous-website-backups.html ∗∗∗ Living Off Windows Land – A New Native File "downldr" ∗∗∗ --------------------------------------------- There are only a couple of default system-signed executables that let you download a file from a Web Server, and every security product and threat hunter specifically looks for them for signs of misuse or abuse by threat actors. --------------------------------------------- https://labs.sentinelone.com/living-off-windows-land-a-new-native-file-down… ∗∗∗ Try2Cry: Ransomware tries to worm ∗∗∗ --------------------------------------------- Try2Cry ransomware adopts USB flash drive spreading using LNK files. The last ransomware that did the same was the infamous Spora. The code of Try2Cry looks oddly familiar, though. --------------------------------------------- https://www.gdatasoftware.com/blog/2020/07/36200-ransomware-tries-to-worm ===================== = Vulnerabilities = ===================== ∗∗∗ Would you like some RCE with your Guacamole? ∗∗∗ --------------------------------------------- [...] Apache Guacamole is a popular infrastructure for remote work, with more than 10 Million docker downloads worldwide. In our research, we discovered that Apache Guacamole is vulnerable to several critical Reverse RDP Vulnerabilities, and is also impacted by a few new vulnerabilities found in FreeRDP. In short, these vulnerabilities allow an attacker, who has already successfully compromised a computer inside the organization, to launch an attack on the Guacamole gateway when an unsuspecting [...] --------------------------------------------- https://research.checkpoint.com/2020/apache-guacamole-rce/ ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (docker.io and imagemagick), Fedora (alpine, firefox, hostapd, and mutt), openSUSE (opera), Red Hat (rh-nginx116-nginx), SUSE (ntp, python3, and systemd), and Ubuntu (firefox, linux, linux-aws, linux-aws-hwe, linux-gcp, linux-gcp-4.15, linux-gke-4.15, linux-hwe, linux-kvm, linux-oem, linux-oracle, linux-raspi2, linux-snapdragon, linux, linux-aws, linux-gcp, linux-kvm, linux-oracle, linux-riscv, linux, linux-azure, linux-gcp, linux-gcp-5.3, linux-hwe, [...] --------------------------------------------- https://lwn.net/Articles/825212/ ∗∗∗ Security Bulletin: Multiple vulnerabilities of Mozilla Firefox (less than Firefox 68.7 ESR ) hava affected Synthetic Playback Agent 8.1.4.0-8.1.4 IF11 + ICAM2019.3.0 – 2020.1.0 ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… ∗∗∗ Security Bulletin: Multiple vulnerabilities of Mozilla Firefox (less than Firefox 68.6.1 ESR) hava affected Synthetic Playback Agent 8.1.4.0-8.1.4 IF11 + ICAM2019.3.0 – 2020.1.0 ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… ∗∗∗ Security Bulletin: Multiple vulnerabilities of Mozilla Firefox (less than Firefox 68.6.1 ESR + CVE-2020-6820) hava affected Synthetic Playback Agent 8.1.4.0-8.1.4 IF11 + ICAM2019.3.0 – 2020.1.0 ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… ∗∗∗ Security Bulletin: IBM Content Navigator is vulnerable to a Prototype Pollution vulnerability ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-content-navigator-is-… ∗∗∗ Security Bulletin: IBM Data Risk Manager is affected by multiple vulnerabilities ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-data-risk-manager-is-… ∗∗∗ Atlassian Jira Software: Mehrere Schwachstellen ∗∗∗ --------------------------------------------- http://www.cert-bund.de/advisoryshort/CB-K20-0664 ∗∗∗ Red Hat JBoss Enterprise Application Platform: Schwachstelle ermöglicht Ausführen von beliebigem Programmcode mit den Rechten des Dienstes ∗∗∗ --------------------------------------------- http://www.cert-bund.de/advisoryshort/CB-K20-0666 -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

As iCalendars files are not included in the list of automatically blocked attachments by email clients like Outlook, the possibility of the maliciously crafted iCalendar falling to the targets’ mailbox is increased. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/phishinvite… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Thursday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (chromium and firefox-esr), Fedora (chromium and ntp), SUSE (ntp and unbound), and Ubuntu (libvncserver). --------------------------------------------- https://lwn.net/Articles/825070/ ∗∗∗ Cisco AnyConnect Secure Mobility Client for Mac OS File Corruption Vulnerability ∗∗∗ --------------------------------------------- https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco… ∗∗∗ Cisco Small Business Smart and Managed Switches Session Management Vulnerability ∗∗∗ --------------------------------------------- https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco… ∗∗∗ Cisco Small Business RV042 and RV042G Routers Cross-Site Scripting Vulnerability ∗∗∗ --------------------------------------------- https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco… ∗∗∗ Cisco Identity Services Engine Stored Cross-Site Scripting Vulnerabilities ∗∗∗ --------------------------------------------- https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco… ∗∗∗ Cisco Digital Network Architecture Center Information Disclosure Vulnerability ∗∗∗ --------------------------------------------- https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco… ∗∗∗ Cisco Unified Customer Voice Portal Information Disclosure Vulnerability ∗∗∗ --------------------------------------------- https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco… ∗∗∗ Cisco Unified Communications Manager Stored Cross-Site Scripting Vulnerability ∗∗∗ --------------------------------------------- https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco… ∗∗∗ Cisco Unified Communications Products Cross-Site Scripting Vulnerability ∗∗∗ --------------------------------------------- https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco… ∗∗∗ Cisco Small Business Smart and Managed Switches Session Management Vulnerability ∗∗∗ --------------------------------------------- https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco… ∗∗∗ Security Bulletin: A vulnerability in IBM Java Runtime affects Rational Asset Analyzer ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-ibm-ja… ∗∗∗ Security Bulletin: Asset Analyzer (RAA) is affected by a WebSphere Application Server vulnerability ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-asset-analyzer-raa-is-aff… ∗∗∗ Security Bulletin: Multiple vulnerabilities in IBM Java Runtime affect Rational Asset Analyzer ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-multiple-vulnerabilities-… ∗∗∗ Security Bulletin: Asset Analyzer (RAA) is affected by a WebSphere Application Server vulnerability ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-asset-analyzer-raa-is-aff… ∗∗∗ Security Bulletin: Asset Analyzer (RAA) is affected by a WebSphere Application Server vulnerability ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-asset-analyzer-raa-is-aff… ∗∗∗ Security Bulletin: Asset Analyzer (RAA) is affected by two WebSphere Application Server vulnerabilities. ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-asset-analyzer-raa-is-aff… ∗∗∗ Security Bulletin: A vulnerability in IBM Java SDK affects IBM Tivoli Netcool Impact (CVE-2020-2654) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-ibm-ja… ∗∗∗ Security Bulletin: Rational Asset Analyzer (RAA) is affected by a WebSphere Application Server vulnerability ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-rational-asset-analyzer-r… ∗∗∗ Security Bulletin: A vulnerability in IBM Java Runtime affect Rational Asset Analyzer. ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-a-vulnerability-in-ibm-ja… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

===================== = End-of-Day report = ===================== Timeframe: Dienstag 30-06-2020 18:00 − Mittwoch 01-07-2020 18:00 Handler: Dimitri Robl Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ A Second Look at CVE-2019-19781 (Citrix NetScaler / ADC) ∗∗∗ --------------------------------------------- In this blog post we will revisit CVE-2019-19781, a Remote Code Execution vulnerability affecting Citrix NetScaler / ADC. We will explore how this issue has been widely abused by various actors and how a hacker turf war led to some actors "adversary patching" the vulnerability in order to prevent secondary compromise by competing adversaries – hiding the true number of vulnerable and compromised devices in the wild. --------------------------------------------- https://blog.fox-it.com/2020/07/01/a-second-look-at-cve-2019-19781-citrix-n… ∗∗∗ Massive Sicherheitsprobleme durch offene Git-Repositorys ∗∗∗ --------------------------------------------- In Deutschland sind Git-Repositorys auf tausenden Servern ungeschützt per Webbrowser zugänglich und Angreifer haben leichtes Spiel beim Abgreifen der Daten. --------------------------------------------- https://heise.de/-4795181 ∗∗∗ Vorsicht beim E-Bike-Kauf: Fake-Shop ebike-quadrat.com bietet günstige E-Bikes an! ∗∗∗ --------------------------------------------- Sommerzeit ist Fahrradzeit. Das denken sich wohl auch BetrügerInnen. Zum Beispiel die unseriösen BetreiberInnen des Fake-Shops ebike-quadrat.com. Auch wenn der Online-Shop auf den ersten Blick vertrauenswürdig wirkt, sollten Sie hier lieber nichts bestellen.
