===================== = End-of-Day report = ===================== Timeframe: Mittwoch 27-07-2022 18:00 − Donnerstag 28-07-2022 18:00 Handler: Stephan Richter Co-Handler: Robert Waldner ===================== = News = ===================== ∗∗∗ LofyLife: malicious npm packages steal Discord tokens and bank card data ∗∗∗ --------------------------------------------- This week, we identified four suspicious packages in the Node Package Manager (npm) repository. All these packages contained highly obfuscated malicious Python and JavaScript code. We dubbed this malicious campaign “LofyLife”. --------------------------------------------- https://securelist.com/lofylife-malicious-npm-packages/107014/ ∗∗∗ Month of PowerShell - PowerShell Remoting, Part 1 ∗∗∗ --------------------------------------------- In this article, we discuss perhaps the most immediately-valuable feature in PowerShell for Windows administrators, the ability to run PowerShell commands on remote systems. --------------------------------------------- https://www.sans.org/blog/powershell-remoting-part-1?msc=rss ∗∗∗ Looking at Patch Gap Vulnerabilities in the VMware ESXi TCP/IP Stack ∗∗∗ --------------------------------------------- In this blog post, we explore another remotely reachable attack surface: ESXi’s TCP/IP stack implemented as a VMkernel module. The most interesting outcome of this analysis is that ESXi’s TCP/IP stack is based on FreeBSD 8.2 and does not include security patches for the vulnerabilities disclosed over the years since that release of FreeBSD. This result also prompted us to analyze the nature of vulnerabilities disclosed in other open-source components used by VMware, such as OpenSLP and ISC-DHCP. --------------------------------------------- https://www.zerodayinitiative.com/blog/2022/7/25/looking-at-patch-gap-vulne… ∗∗∗ Vorsicht vor Fake Last-Minute-Angeboten auf Mallorca und Ibiza! ∗∗∗ --------------------------------------------- Die Hitze schlägt zu und Kurzentschlossene suchen nach den letzten verfügbaren Ferienhäusern, um ein paar Tage am Meer zu verbringen. Doch Vorsicht: Kriminelle versuchen Sie mit attraktiven Angeboten in die Falle zu locken! Wird eine Vorauszahlung für ein Ferienhaus verlangt, brechen Sie den Kontakt ab, Ihr Geld ist sonst verloren! --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-vor-fake-last-minute-angebo… ∗∗∗ MFA hilft gegen Ransomware ∗∗∗ --------------------------------------------- Die Multi-Faktor-Authentifizierung (MFA) funktioniert.

The module doesn't sufficiently sanitize the title of a block as displayed in the admin UI when a site administrator edits a context block reaction. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer blocks". --------------------------------------------- https://www.drupal.org/sa-contrib-2022-049 ∗∗∗ Sicherheitsupdates: Angreifer könnten Veritas NetBackup vielfältig attackieren ∗∗∗ --------------------------------------------- Die Entwickler haben in aktuellen Versionen der Backuplösung NetBackup von Veritas unter anderem kritische Lücken geschlossen. --------------------------------------------- https://heise.de/-7192562 ∗∗∗ Security updates for Thursday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (firefox-esr), Fedora (chromium, gnupg1, java-17-openjdk, osmo, and podman), Oracle (grafana and java-17-openjdk), Red Hat (389-ds:1.4, container-tools:rhel8, grafana, java-1.8.0-openjdk, java-11-openjdk, java-17-openjdk, kernel, kernel-rt, kpatch-patch, pandoc, squid, and squid:4), Slackware (samba), and SUSE (crash, mariadb, pcre2, python-M2Crypto, virtualbox, and xen). --------------------------------------------- https://lwn.net/Articles/902795/ ∗∗∗ Trend Micro Produkte: Schwachstelle ermöglicht Privilegieneskalation ∗∗∗ --------------------------------------------- Ein lokaler Angreifer kann eine Schwachstelle in Trend Micro Apex One und Trend Micro Worry-Free Business Security ausnutzen, um seine Privilegien zu erhöhen. --------------------------------------------- https://wid.cert-bund.de/portal/wid/securityadvisory?name=WID-SEC-2022-0850 ∗∗∗ Atlassian Jira Software: Schwachstelle ermöglicht Offenlegung von Informationen ∗∗∗ --------------------------------------------- Ein entfernter, authentisierter Angreifer kann eine Schwachstelle in Atlassian Jira Software ausnutzen, um Informationen offenzulegen. --------------------------------------------- https://wid.cert-bund.de/portal/wid/securityadvisory?name=WID-SEC-2022-0849 ∗∗∗ McAfee Agent: Schwachstelle ermöglicht Privilegieneskalation ∗∗∗ --------------------------------------------- Ein lokaler Angreifer kann eine Schwachstelle im McAfee Agent ausnutzen, um seine Privilegien zu erhöhen und beliebigen Code mit Administratorrechten auszuführen. --------------------------------------------- https://wid.cert-bund.de/portal/wid/securityadvisory?name=WID-SEC-2022-0848 ∗∗∗ Jenkins: Mehrere Schwachstellen ∗∗∗ --------------------------------------------- Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Jenkins ausnutzen, um einen Cross Site Scripting oder CSRF Angriff durchzuführen, Sicherheitsvorkehrungen zu umgehen, Informationen offenzulegen oder Daten zu manipulieren --------------------------------------------- https://wid.cert-bund.de/portal/wid/securityadvisory?name=WID-SEC-2022-0852 ∗∗∗ Security Bulletin: OpenSSL for IBM i is vulnerable to arbitrary command execution (CVE-2022-2068) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-openssl-for-ibm-i-is-vuln… ∗∗∗ Security Bulletin: IBM Cloud Transformation Advisor is vulnerable to multiple vulnerabilities ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-cloud-transformation-… ∗∗∗ Security Bulletin: Vulnerability in Golang Go affects IBM Spectrum Protect Plus Container Backup and Restore for Kubernetes and Red Hat OpenShift (CVE-2022-29526) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-vulnerability-in-golang-g… ∗∗∗ Security Bulletin: IBM WebSphere Application Server Liberty is vulnerable to Identity Spoofing (CVE-2022-22476) ∗∗∗ --------------------------------------------- https://www.ibm.com/blogs/psirt/security-bulletin-ibm-websphere-application… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

Wir raten dazu, Abstand von den Angeboten zu nehmen, denn die Leistungen werden Erfahrungsberichten nach minderwertig oder gar nicht erbracht und auch frühere Mitarbeiter:innen sowie die Bewertungsseite Trustpilot warnen vor dem Angebot. --------------------------------------------- https://www.watchlist-internet.at/news/studentinnen-aufgepasst-akademisches… ∗∗∗ Untangling KNOTWEED: European private-sector offensive actor using 0-day exploits ∗∗∗ --------------------------------------------- MSTIC and MSRC disclose technical details of a private-sector offensive actor (PSOA) tracked as KNOTWEED using multiple Windows and Adobe 0-day exploits, including one for the recently patched CVE-2022-22047, in limited and targeted attacks against European and Central American customers. --------------------------------------------- https://www.microsoft.com/security/blog/2022/07/27/untangling-knotweed-euro… ∗∗∗ Month of PowerShell: Fileless Malware with Get-Clipboard ∗∗∗ --------------------------------------------- In this article we look at using PowerShell maliciously while evading detection. --------------------------------------------- https://www.sans.org/blog/fileless-malware-get-clipboard/ ∗∗∗ DHL Phishing Page Uses Telegram Bot for Exfiltration ∗∗∗ --------------------------------------------- One of the quickest ways for an attacker to harvest financial data, credentials, and sensitive personal information is through phishing. These social engineering attacks can typically be found masquerading as a trusted or recognizable service, intent on tricking unsuspecting users into submitting sensitive information on the attacker’s customized web page. --------------------------------------------- https://blog.sucuri.net/2022/07/dhl-phishing-page-uses-telegram-bot-for-exf… ∗∗∗ Inside Matanbuchus: A Quirky Loader ∗∗∗ --------------------------------------------- This blog post will shed light on Matanbuchus’ main stage, the second stage of the loader. From our point of view, the second stage is the more interesting component of the loader, as it involves many payload loading techniques. By dissecting the loader’s features and capabilities, we will attempt to answer whether Matanbuchus is a loader malware, as it markets itself, or if it is more like a bot service. --------------------------------------------- https://www.cyberark.com/resources/threat-research-blog/inside-matanbuchus-… ∗∗∗ Top 10 Awesome Open-Source Adversary Simulation Tools ∗∗∗ --------------------------------------------- Cyberattack simulation, aka Threat Simulation, is an emerging IT security technology that can help discover gaps, vulnerabilities, and misconfigurations in your security infrastructure. We will take a look at the need for adversary simulation and the top ten open-source adversary simulation tools. --------------------------------------------- https://fourcore.io/blogs/top-10-open-source-adversary-emulation-tools ∗∗∗ Looking at Patch Gap Vulnerabilities in the VMware ESXi TCP/IP Stack ∗∗∗ --------------------------------------------- Over the last few years, multiple VMware ESXi remote, unauthenticated code execution vulnerabilities have been publicly disclosed. Some were also found to be exploited in the wild. Since these bugs were found in ESXi’s implementation of the SLP service, VMware provided workarounds to turn off the service. VMware also disabled the service by default starting with ESX 7.0 Update 2c. In this blog post, we explore another remotely reachable attack surface: ESXi’s TCP/IP stack --------------------------------------------- https://www.thezdi.com/blog/2022/7/25/looking-at-patch-gap-vulnerabilities-… ∗∗∗ What Talos Incident Response learned from a recent Qakbot attack hijacking old email threads ∗∗∗ --------------------------------------------- In a recent malspam campaign delivering the Qakbot banking trojan, Cisco Talos Incident Response (CTIR) observed the adversary using aggregated, old email threads from multiple organizations that we assess were likely harvested during the 2021 ProxyLogon-related compromises targeting vulnerable Microsoft Exchange servers. This campaign relies on external thread hijacking, whereby the adversary is likely using a bulk aggregation of multiple organizations’ harvested emails to launch focused phishing campaigns against previously uncompromised organizations. This differs from the more common approach to thread hijacking, in which attackers use a single compromised organization’s emails to deliver their threat. ---------------------------------------------
