===================== = End-of-Day report = ===================== Timeframe: Dienstag 02-04-2024 18:00 − Mittwoch 03-04-2024 18:00 Handler: Michael Schlagenhaufer Co-Handler: Thomas Pribitzer ===================== = News = ===================== ∗∗∗ NIS2-Begutachtungsverfahren gestartet ∗∗∗ --------------------------------------------- Die Regierung hat am 3. April 2024 das Cybersicherheitsgesetz zur europäischen NIS2-Verordnung in Begutachtung geschickt. --------------------------------------------- https://www.bmi.gv.at/news.aspx?id=7567384169746C75366D413D ∗∗∗ Kritik nach Cyberangriff: Microsoft hat seine Kronjuwelen nicht im Griff ∗∗∗ --------------------------------------------- Ein im Sommer 2023 festgestellter Cyberangriff auf Microsofts Server hatte für einige Kunden verheerende Folgen.

[..] The Jia Tan persona has vanished since the backdoor was discovered [..] In fact, the only real footprints Jia Tan appears to have left behind were their contributions to the open source development community, where they were a prolific contributor: Disturbingly, Jia Tan’s first code change was to the “libarchive” compression library, another very widely used open source component. [..] In total, Jia Tan made 6,000 code changes to at least seven projects between 2021 and February 2024 [..] Security researchers agree, at least, that it’s unlikely that Jia Tan is a real person, or even one person working alone. Instead, it seems clear that the persona was the online embodiment of a new tactic from a new, well-organized organization—a tactic that nearly worked. --------------------------------------------- https://www.wired.com/story/jia-tan-xz-backdoor/ ∗∗∗ XZ Utils Backdoor Attack Brings Another Similar Incident to Light ∗∗∗ --------------------------------------------- In a post on Mastodon, Hans-Christoph Steiner, a maintainer of F-Droid, recalled a similar story from 2020, when an individual attempted to get F-Droid developers to add what later was determined to be a SQL injection vulnerability. That attempt was unsuccessful, but has some similarities to the XZ incident. --------------------------------------------- https://www.securityweek.com/xz-utils-backdoor-attack-brings-another-simila… ∗∗∗ Distinctive Campaign Evolution of Pikabot Malware ∗∗∗ --------------------------------------------- PikaBot is a malicious backdoor that has been active since early 2023. Its modular design is comprised of a loader and a core component. [..] During February 2024, McAfee Labs observed a significant change in the campaigns that distribute Pikabot. --------------------------------------------- https://www.mcafee.com/blogs/other-blogs/mcafee-labs/distinctive-campaign-e… ∗∗∗ Hohe Handyrechnung durch ungewolltes Abo? ∗∗∗ --------------------------------------------- Per E-Mail oder SMS werden Sie plötzlich von Ihrem Mobilfunkanbieter darüber informiert, dass Sie ein Abo abgeschlossen haben.

===================== = End-of-Day report = ===================== Timeframe: Freitag 29-03-2024 18:00 − Dienstag 02-04-2024 18:00 Handler: Thomas Pribitzer Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ Staatlich gesponserte "Entwicklung" quelloffener Software ∗∗∗ --------------------------------------------- Wer auf der Suche nach einer kurzen Zusammenfassung der Geschehnisse rund um die (höchstwahrscheinliche) Backdoor in xz, CVE-2024-3094, ist, möge einen Blick auf diese durch den Sicherheitsforscher Thomas Roccia erstellte Grafik werfen. Darin sind die wichtigsten Details zusammengefasst, die in den folgenden Absätze wesentlich ausführlicher beleuchtet werden. Alternativ hätte dieser Blogpost auch einen deutlich knackigeren Titel haben können - "CVE-2024-3094", um jene geht es in diesem Beitrag nämlich. --------------------------------------------- https://cert.at/de/blog/2024/4/staatlich-gesponserte-entwicklung-quelloffen… ∗∗∗ The amazingly scary xz sshd backdoor, (Mon, Apr 1st) ∗∗∗ --------------------------------------------- The whole story around this is both fascinating and scary – and I’m sure will be told around numerous time, so in this diary I will put some technical things about the backdoor that I reversed for quite some time (and I have a feeling I could spend 2 more weeks on this). [..] Let’s take a look at couple of fascinating things in this backdoor. --------------------------------------------- https://isc.sans.edu/diary/rss/30802 ∗∗∗ On Cybersecurity Alert Levels ∗∗∗ --------------------------------------------- Last week I was invited to provide input to a tabletop exercise for city-level crisis managers on cyber security risks and the role of CSIRTs. The organizers brought a color-coded threat-level sheet (based on the CISA Alert Levels) to the discussion and asked whether we also do color-coded alerts in Austria and what I think of these systems. My answer was negative on both questions, and I think it might be useful if I explain my rationale here. --------------------------------------------- https://cert.at/en/blog/2024/4/on-cybersecurity-alert-levels ∗∗∗ Heartbleed is 10 Years Old – Farewell Heartbleed, Hello QuantumBleed! ∗∗∗ --------------------------------------------- Heartbleed made most certificates vulnerable. The future problem is that quantum decryption will make all certificates and everything else using RSA encryption vulnerable to everyone. --------------------------------------------- https://www.securityweek.com/heartbleed-is-10-years-old-farewell-heartbleed… ∗∗∗ From OneNote to RansomNote: An Ice Cold Intrusion ∗∗∗ --------------------------------------------- In late February 2023, threat actors rode a wave of initial access using Microsoft OneNote files. In this case, we observed a threat actor deliver IcedID using this method. After loading IcedID and establishing persistence, there were no further actions, other than beaconing for over 30 days. The threat actor used Cobalt Strike and AnyDesk to target a file server and a backup server. The threat actor used FileZilla to exfiltrate data from the network before deploying Nokoyawa ransomware. --------------------------------------------- https://thedfirreport.com/2024/04/01/from-onenote-to-ransomnote-an-ice-cold… ∗∗∗ Adversaries are leveraging remote access tools now more than ever — here’s how to stop them ∗∗∗ --------------------------------------------- While there are many legitimate uses for this software, adversaries are also finding ways to use them for command and control in their campaigns. --------------------------------------------- https://blog.talosintelligence.com/adversaries-are-leveraging-remote-access… ∗∗∗ Earth Freybug Uses UNAPIMON for Unhooking Critical APIs ∗∗∗ --------------------------------------------- This article provides an in-depth look into two techniques used by Earth Freybug actors: dynamic-link library (DLL) hijacking and application programming interface (API) unhooking to prevent child processes from being monitored via a new malware we’ve discovered and dubbed UNAPIMON. --------------------------------------------- https://www.trendmicro.com/en_us/research/24/d/earth-freybug.html ===================== = Vulnerabilities = ===================== ∗∗∗ Update #1: Kritische Sicherheitslücke/Hintertüre in xz-utils (CVE-2024-3094) ∗∗∗ --------------------------------------------- In den Versionen 5.6.0 und 5.6.1 der weit verbreiteten Bibliothek xz-utils wurde eine Hintertür entdeckt. xz-utils wird häufig zur Komprimierung von Softwarepaketen, Kernel-Images und initramfs-Images verwendet. Die Lücke ermöglicht es nicht authentifizierten Angreifer:innen, die sshd-Authentifizierung auf verwundbaren Systemen zu umgehen und unauthorisierten Zugriff auf das gesamte System zu erlangen. Aktuell liegen uns keine Informationen über eine aktive Ausnutzung vor. --------------------------------------------- https://cert.at/de/warnungen/2024/3/kritische-sicherheitslucke-in-fedora-41… ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by Arch Linux (xz), Debian (libvirt, mediawiki, util-linux, and xz-utils), Fedora (apache-commons-configuration, cockpit, ghc-base64, ghc-hakyll, ghc-isocline, ghc-toml-parser, gitit, gnutls, pandoc, pandoc-cli, patat, podman-tui, prometheus-podman-exporter, seamonkey, suricata, and xen), Gentoo (XZ utils), Mageia (aide & mhash, emacs, microcode, opensc, and squid), Red Hat (ruby:3.1), and SUSE (kanidm and qpid-proton). --------------------------------------------- https://lwn.net/Articles/967851/ ∗∗∗ Security updates for Tuesday ∗∗∗ --------------------------------------------- Security updates have been issued by Fedora (kernel and webkitgtk), Mageia (unixODBC and w3m), and SUSE (libvirt, netty, netty-tcnative, and perl-DBD-SQLite). --------------------------------------------- https://lwn.net/Articles/967959/ ∗∗∗ Security Flaw in WP-Members Plugin Leads to Script Injection ∗∗∗ --------------------------------------------- A cross-site scripting vulnerability in the WP-Members Membership plugin could allow attackers to inject scripts into user profile pages. --------------------------------------------- https://www.securityweek.com/security-flaw-in-wp-members-plugin-leads-to-sc… ∗∗∗ Bitdefender hat hochriskante Sicherheitslücke abgedichtet ∗∗∗ --------------------------------------------- Durch eine Sicherheitslücke konnten Angreifer auf Rechnern mit Bitdefender-Virenschutz ihre Rechte ausweiten.

If you're lucky, logs are already indexed in real-time in a log management solution and you can automatically launch some hunting queries. If that's not the case, you can download all logs on a local system or a cloud instance and index them manually. But it's not always the easiest/fastest way due to the amount of data to process. These days, I'm always trying to process data as close as possible of their location/source and only download the investigation results. --------------------------------------------- https://isc.sans.edu/diary/rss/30792 ∗∗∗ New Linux Bug Could Lead to User Password Leaks and Clipboard Hijacking ∗∗∗ --------------------------------------------- Details have emerged about a vulnerability impacting the "wall" command of the util-linux package that could be potentially exploited by a bad actor to leak a users password or alter the clipboard on certain Linux distributions. The bug, tracked as CVE-2024-28085, has been codenamed WallEscape by security researcher Skyler Ferrante. --------------------------------------------- https://thehackernews.com/2024/03/new-linux-bug-could-lead-to-user.html ∗∗∗ Dormakaba Locks Used in Millions of Hotel Rooms Could Be Cracked in Seconds ∗∗∗ --------------------------------------------- Security vulnerabilities discovered in Dormakabas Saflok electronic RFID locks used in hotels could be weaponized by threat actors to forge keycards and stealthily slip into locked rooms. [..] They were reported to the Zurich-based company in September 2022. [..] Dormakaba is estimated to have updated or replaced 36% of the impacted locks as of March 2024 as part of a rollout process that commenced in November 2023. Some of the vulnerable locks have been in use since 1988. --------------------------------------------- https://thehackernews.com/2024/03/dormakaba-locks-used-in-millions-of.html ∗∗∗ Pentagon Outlines Cybersecurity Strategy for Defense Industrial Base ∗∗∗ --------------------------------------------- US Defense Department releases defense industrial base cybersecurity strategy with a focus on four key goals. [..] The cybersecurity strategy published this week covers fiscal years 2024 through 2027 and its primary mission is to ensure the generation, reliability and preservation of warfighting capabilities by protecting operational capabilities, sensitive information, and product integrity. --------------------------------------------- https://www.securityweek.com/pentagon-outlines-cybersecurity-strategy-for-d… ∗∗∗ E-Mail über „fragwürdige Transaktion“ führt zu Schadsoftware ∗∗∗ --------------------------------------------- Aktuell versenden Kriminelle wahllos E-Mails an Unternehmen mit dem Betreff „Questionable Transaction on Credit Card - Need Explanation“. Die Kriminellen bitten darum, auf die E-Mail zu antworten, um zu erklären, woher die „fragwürdige Transaktion“ auf der Kreditkarte kommt. Wer antwortet, erhält prompt eine neue E-Mail. Diesmal wird ein Kontoauszug als Beweis mitgeschickt. Das behaupten zumindest die Kriminellen. --------------------------------------------- https://www.watchlist-internet.at/news/e-mail-ueber-fragwuerdige-transaktio… ∗∗∗ Stories from the SOC Part 1: IDAT Loader to BruteRatel ∗∗∗ --------------------------------------------- In August 2023, Rapid7 identified a new malware loader named the IDAT Loader. Malware loaders are a type of malicious software designed to deliver and execute additional malware onto a victim's system. [..] In this two-part blog series, we will examine the attack chain observed in two separate incidents, offering in-depth analysis of the malicious behavior detected. --------------------------------------------- https://www.rapid7.com/blog/post/2024/03/28/stories-from-the-soc-part-1-ida… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (chromium), Fedora (apache-commons-configuration, chromium, csmock, ofono, onnx, php-tcpdf, and podman-tui), Mageia (curl), Oracle (libreoffice), Slackware (coreutils, seamonkey, and util), SUSE (minidlna, PackageKit, and podman), and Ubuntu (linux-azure-6.5 and linux-intel-iotg, linux-intel-iotg-5.15). --------------------------------------------- https://lwn.net/Articles/967134/ ∗∗∗ 26 Security Issues Patched in TeamCity ∗∗∗ --------------------------------------------- TeamCity 2024.03, released on March 27, patches 26 ‘security problems’, according to JetBrains. The company highlighted that it’s not sharing the details of security-related issues “to avoid compromising clients that keep using previous bugfix and/or major versions of TeamCity”. --------------------------------------------- https://www.securityweek.com/26-security-issues-patched-in-teamcity/ ∗∗∗ IBM Security Bulletins ∗∗∗ --------------------------------------------- https://www.ibm.com/support/pages/bulletin/ ∗∗∗ F5: K000139084 : DNS vulnerability CVE-2023-50868 ∗∗∗ --------------------------------------------- https://my.f5.com/manage/s/article/K000139084 -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

As we talk about in FOR577, depending on which tool you run on a live system and how you define "installed" you may get different answers, but at least on the live system you can use things like apt list or dpkg -l or rpm -qa or whatever to try to list them, but if all you have is a disk image, what do you do? --------------------------------------------- https://isc.sans.edu/diary/rss/30774 ∗∗∗ Agent Teslas New Ride: The Rise of a Novel Loader ∗∗∗ --------------------------------------------- This blog provides an in-depth analysis of a newly identified loader, highlighting the attack's evasiveness and the advanced tactics, techniques, and procedures (TTPs) used in both the loader and its command and control (C2) framework. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/agent-tesla… ∗∗∗ The Darkside of TheMoon ∗∗∗ --------------------------------------------- The Black Lotus Labs team at Lumen Technologies has identified a multi-year campaign targeting end-of-life (EoL) small home/small office (SOHO) routers and IoT devices, associated with an updated version of “TheMoon” malware. [..] While Lumen has previously documented this malware family, our latest tracking has shown TheMoon appears to enable Faceless’ growth at of a rate of nearly 7,000 new users per week. Through Lumen’s global network visibility, Black Lotus Labs has identified the logical map of the Faceless proxy service, including a campaign that began in the first week of March 2024 that targeted over 6,000 ASUS routers in less than 72 hours. --------------------------------------------- https://blog.lumen.com/the-darkside-of-themoon/ ∗∗∗ Recent ‘MFA Bombing’ Attacks Targeting Apple Users ∗∗∗ --------------------------------------------- Several Apple customers recently reported being targeted in elaborate phishing attacks that involve what appears to be a bug in Apples password reset feature. In this scenario, a targets Apple devices are forced to display dozens of system-level prompts that prevent the devices from being used until the recipient responds "Allow" or "Dont Allow" to each prompt. [..] But the attackers in this campaign had an ace up their sleeves: Patel said after denying all of the password reset prompts from Apple, he received a call on his iPhone that said it was from Apple Support (the number displayed was 1-800-275-2273, Apple’s real customer support line). --------------------------------------------- https://krebsonsecurity.com/2024/03/recent-mfa-bombing-attacks-targeting-ap… ∗∗∗ Suspicious NuGet Package Harvesting Information From Industrial Systems ∗∗∗ --------------------------------------------- A suspicious NuGet package likely targets developers working with technology from Chinese firm Bozhon. --------------------------------------------- https://www.securityweek.com/suspicious-nuget-package-harvesting-informatio… ∗∗∗ Agenda Ransomware Propagates to vCenters and ESXi via Custom PowerShell Script ∗∗∗ --------------------------------------------- This blog entry discusses the Agenda ransomware groups use of its latest Rust variant to propagate to VMWare vCenter and ESXi servers. --------------------------------------------- https://www.trendmicro.com/en_us/research/24/c/agenda-ransomware-propagates… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Tuesday ∗∗∗ --------------------------------------------- Security updates have been issued by CentOS (kernel), Debian (firefox-esr), Fedora (webkitgtk), Mageia (curaengine & blender and gnutls), Red Hat (firefox, grafana, grafana-pcp, libreoffice, nodejs:18, and thunderbird), SUSE (glade), and Ubuntu (crmsh, debian-goodies, linux-aws, linux-aws-6.5, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-oracle, linux-azure, linux-azure-5.4, linux-oracle, linux-oracle-5.15, pam, and thunderbird). --------------------------------------------- https://lwn.net/Articles/966678/ ∗∗∗ WebKitGTK and WPE WebKit Security Advisory WSA-2024-0002 ∗∗∗ --------------------------------------------- Several vulnerabilities were discovered in WebKitGTK and WPE WebKit.

[..] Die NaurLegal-Kampagne täuscht Legitimität vor, indem sie PDF-Dateien mit seriös anmutenden Dateinamen wie „Rechnung_[Nummer]_von_[Name der Anwaltskanzlei].pdf“ erstellt und versendet. [..] Die Infrastruktur der NaurLegal-Kampagne umfasst Domänen, die mit WikiLoader verknüpft sind und deren Folgeaktivitäten auf eine Zuordnung zu dieser Malware-Familie schließen lassen. WikiLoader ist bekannt für ausgefeilte Verschleierungstechniken, wie z. B. die Überprüfung von Wikipedia-Antworten auf bestimmte Zeichenfolgen, um Sandbox-Umgebungen zu umgehen. --------------------------------------------- https://www.zdnet.de/88414996/phishing-mit-gefaelschten-rechnungen-von-anwa… ∗∗∗ CISA and FBI Release Secure by Design Alert to Urge Manufacturers to Eliminate SQL Injection Vulnerabilities ∗∗∗ --------------------------------------------- Today, CISA and the Federal Bureau of Investigation (FBI) released a joint Secure by Design Alert, Eliminating SQL Injection Vulnerabilities in Software.

This is the first time we have seen this APT29 cluster target political parties, indicating a possible area of emerging operational focus beyond the typical targeting of diplomatic missions. Based on the SVR’s responsibility to collect political intelligence and this APT29 cluster’s historical targeting patterns, we judge this activity to present a broad threat to European and other Western political parties from across the political spectrum. --------------------------------------------- https://www.mandiant.com/resources/blog/apt29-wineloader-german-political-p… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (cacti, firefox-esr, freeipa, gross, libnet-cidr-lite-perl, python2.7, python3.7, samba, and thunderbird), Fedora (amavis, chromium, clojure, firefox, gnutls, kubernetes, and tcpreplay), Mageia (freeimage, libreswan, nodejs-hawk, and python, python3), Oracle (golang, nodejs, nodejs:16, and postgresql-jdbc), Slackware (emacs and mozilla), SUSE (dav1d, ghostscript, go1.22, indent, kernel, openvswitch, PackageKit, python-uamqp, rubygem-rack-1_4, shadow, ucode-intel, xen, and zziplib), and Ubuntu (firefox, graphviz, libnet-cidr-lite-perl, and qpdf). --------------------------------------------- https://lwn.net/Articles/966611/ ∗∗∗ Firefox: Notfall-Update schließt kritische Sicherheitslücken ∗∗∗ --------------------------------------------- Die Mozilla-Entwickler haben zwei kritische Sicherheitslücken mit dem Update auf Firefox 124.0.1 und Firefox ESR 115.9.1 geschlossen. --------------------------------------------- https://heise.de/-9664148 ∗∗∗ Sicherheitslücken in Microsofts WiX-Installer-Toolset gestopft ∗∗∗ --------------------------------------------- Das quelloffene WiX-Installer-Toolset von Microsoft hat zwei Sicherheitslücken.
