===================== = End-of-Day report = ===================== Timeframe: Mittwoch 14-02-2024 18:00 − Donnerstag 15-02-2024 18:00 Handler: Thomas Pribitzer Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ Warnung vor kritischer Outlook RCE-Schwachstelle CVE-2024-21413 ∗∗∗ --------------------------------------------- In Microsoft Outlook wurde eine als kritisch eingestufte CVE-2024-21413 bekannt, die mit den Februar 2024 Sicherheitsupdates geschlossen wird. Die Remote Code Execution-Schwachstelle lässt sich geradezu trivial ausnutzen. [..] Die von Checkpoint Security aufgedeckte Schwachstelle ermöglicht einem Angreifer die geschützte Office-Ansicht zu umgehen und das Dokument im Bearbeitungsmodus statt im geschützten Modus zu öffnen. [..] Dazu muss der Angreifer einen bösartigen Link erstellen, der das Protected View-Protokoll umgeht. Das führt dann zum Abfluss lokaler NTLM-Anmeldeinformationen und zur Remotecodeausführung (RCE). --------------------------------------------- https://www.borncity.com/blog/2024/02/15/warnung-vor-kritischer-outlook-rce… ∗∗∗ Nachlese zu CU 14 für Exchange 2019 und Schwachstelle CVE-2024-21410 (Feb. 2024) ∗∗∗ --------------------------------------------- Zum 13. Februar 2024 wurde ja eine kritische Schwachstelle CVE-2024-21410 in Microsoft Exchange Server öffentlich. [..] Was ist mit Exchange Server 2016 und was muss ich tun, um vor CVE-2024-21410 geschützt zu sein. Hier eine Nachlese mit einem groben Abriss. --------------------------------------------- https://www.borncity.com/blog/2024/02/15/nachlese-zu-cu-14-fr-exchange-2019… ∗∗∗ New ‘Gold Pickaxe’ Android, iOS malware steals your face for fraud ∗∗∗ --------------------------------------------- A new iOS and Android trojan named GoldPickaxe employs a social engineering scheme to trick victims into scanning their faces and ID documents, which are believed to be used to generate deepfakes for unauthorized banking access. --------------------------------------------- https://www.bleepingcomputer.com/news/security/new-gold-pickaxe-android-ios… ∗∗∗ QR Phishing. Fact or Fiction? ∗∗∗ --------------------------------------------- To understand the attack you need understand the challenge that the attacker faces. Currently, most initial access attempts are carried out with social engineering, commonly phishing. Why is that? Well, it looks like people have finally got good at patching. According to the 2022 Verizon data breach incident report only 5% of data breaches investigated by them were caused by software vulnerabilities. --------------------------------------------- https://www.pentestpartners.com/security-blog/qr-phishing-fact-or-fiction/ ∗∗∗ Vorsicht vor dieser Fake Erste Bank SMS ∗∗∗ --------------------------------------------- Kriminelle versenden SMS im Namen der Erste Bank bzw. George. Darin behaupten sie, dass eine Überweisung über einen hohen Geldbetrag freigegeben oder ein Darlehen aufgenommen wurde und bitten um Kontaktaufnahmen. Kontaktieren Sie nicht die angegebene Nummer, Sie werden dazu verleitet Schadsoftware zu installieren! --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-vor-dieser-fake-erste-bank-… ∗∗∗ The Complete Guide to Advanced Persistent Threats ∗∗∗ --------------------------------------------- Understanding the mechanics and implications of APTs is essential to safeguard organizations and individuals. In this comprehensive guide, we explore the world of APTs, explaining their nature, mechanisms, and the best strategies to counteract them. --------------------------------------------- https://www.emsisoft.com/en/blog/44815/the-complete-guide-to-advanced-persi… ∗∗∗ TinyTurla Next Generation - Turla APT spies on Polish NGOs ∗∗∗ --------------------------------------------- Talos, in cooperation with CERT.NGO, investigated another compromise by the Turla threat actor, with a new backdoor quite similar to TinyTurla, that we are calling TinyTurla-NG (TTNG). [..] Talos identified the existence of three different TinyTurla-NG samples, but only obtained access to two of them. This campaign’s earliest compromise date was Dec. 18, 2023, and was still active as recently as Jan. 27, 2024. However, we assess that the campaign may have started as early as November 2023 based on malware compilation dates. --------------------------------------------- https://blog.talosintelligence.com/tinyturla-next-generation/ ===================== = Vulnerabilities = ===================== ∗∗∗ AlphaESS Wechselrichter: WLAN-Zugang mit unveränderlichem Passwort ∗∗∗ --------------------------------------------- Wechselrichter und Speichersysteme von AlphaESS kommen mit optionalem WLAN-Modul.

Die Preise für die neuen Geräte bewegen sich zum Marktstart zwischen 780 und 1800 Euro für die unterschiedlichen Modelle. Um vieles billiger versprechen Kriminelle das Gerät. Für 269 Euro per Nachnahme gibt es das teuerste Gerät auf shop.mgmmgme.shop. So viel ist sicher: Das versprochene Gerät wird hier nie geliefert und Zahlungen per Nachnahme sind verloren. --------------------------------------------- https://www.watchlist-internet.at/news/fake-angebote-fuer-samsungs-galaxy-s… ∗∗∗ The Risks of the #MonikerLink Bug in Microsoft Outlook and the Big Picture ∗∗∗ --------------------------------------------- Recently, Check Point Research released a white paper titled “The Obvious, the Normal, and the Advanced: A Comprehensive Analysis of Outlook Attack Vectors”, detailing various attack vectors on Outlook to help the industry understand the security risks the popular Outlook app may bring into organizations. As mentioned in the paper, we discovered an interesting security issue in Outlook when the app handles specific hyperlinks. In this blog post, we will share our research on the issue with the security community and help defend against it. We will also highlight the broader impact of this bug in other software. --------------------------------------------- https://research.checkpoint.com/2024/the-risks-of-the-monikerlink-bug-in-mi… ∗∗∗ TicTacToe Dropper ∗∗∗ --------------------------------------------- We analyzed multiple samples of this dropper. The executable malware file was usually delivered through an .iso file. From cases directly observed in the wild, these iso files were delivered to the victim via phishing as an attachment (T1566.001). This technique of packing malware inside an iso file is typically employed to avoid detection by antivirus software and as a mark-of-the-web (MOTW) bypass technique (T1553.005). --------------------------------------------- https://feeds.fortinet.com/~/869921006/0/fortinet/blogs~TicTacToe-Dropper ===================== = Vulnerabilities = ===================== ∗∗∗ Patchday: Adobe schließt Schadcode-Lücken in Acrobat & Co. ∗∗∗ --------------------------------------------- Für mehrere Adobe-Produkte sind wichtige Sicherheitsupdates erschienen.

===================== = End-of-Day report = ===================== Timeframe: Montag 12-02-2024 18:00 − Dienstag 13-02-2024 18:00 Handler: Thomas Pribitzer Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ The (D)Evolution of Pikabot ∗∗∗ --------------------------------------------- Pikabot is a malware loader that originally emerged in early 2023. Over the past year, ThreatLabz has been tracking the development of Pikabot and its modus operandi. There was a significant increase in usage in the second half of 2023 following the FBI-led takedown of Qakbot. This was likely the result of a BlackBasta ransomware affiliate replacing Qakbot with Pikabot for initial access. However, Pikabot ceased activity shortly after Christmas 2023, with its version number being 1.1.19 at that time. In recent campaigns, which started in February 2024, Pikabot reemerged with significant changes in its code base and structure. --------------------------------------------- https://www.zscaler.com/blogs/security-research/d-evolution-pikabot ∗∗∗ GMX, Web.de, Online-Dienste: Angriffe auf Zugangsdaten nehmen zu ∗∗∗ --------------------------------------------- Etwas alarmistisch melden einige Medien, dass es vermehrt Angriffe auf Zugangskonten von GMX oder Web.de gebe, die unter anderem sehr populäre Webmail-Dienste bereitstellen. Es werden dort bei zahlreichen Konten sehr hohe Zahlen für fehlerhafte Log-in-Versuche angezeigt. Es handelt sich offenbar um die alltäglichen Angriffe auf Zugangsdaten von Cyberkriminellen, die versuchen, mit gestohlenen Accountinformationen auf Online-Dienste zuzugreifen. --------------------------------------------- https://www.heise.de/-9626994 ∗∗∗ Vorsicht vor gefälschten WKÖ-E-Mails ∗∗∗ --------------------------------------------- Kriminelle geben sich als Wirtschaftskammer Österreich aus und bitten Unternehmen in einem E-Mail, Kontaktdaten zu aktualisieren. Klicken Sie keinesfalls auf den Link, Sie werden auf eine gefälschte WKÖ-Seite geführt. Dort stehlen Kriminelle Firmen- und Bankdaten. --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-vor-gefaelschten-wkoe-e-mai… ∗∗∗ Directory.ReadWrite.All Is Not As Powerful As You Might Think ∗∗∗ --------------------------------------------- Directory.ReadWrite.All is an MS Graph permission that is frequently cited as granting high amounts of privilege, even being equated to the Global Admin Entra ID role [..] Misleading or incorrect documentation create most of the misconceptions regarding this permission. --------------------------------------------- https://posts.specterops.io/directory-readwrite-all-is-not-as-powerful-as-y… ∗∗∗ Ongoing Microsoft Azure account hijacking campaign targets executives ∗∗∗ --------------------------------------------- A phishing campaign detected in late November 2023 has compromised hundreds of user accounts in dozens of Microsoft Azure environments, including those of senior executives. --------------------------------------------- https://www.bleepingcomputer.com/news/security/ongoing-microsoft-azure-acco… ∗∗∗ Fileless Revenge RAT Malware ∗∗∗ --------------------------------------------- AhnLab SEcurity intelligence Center (ASEC) recently discovered the distribution of Revenge RAT malware that had been developed based on legitimate tools. It appears that the attackers have used tools such as ‘smtp-validator’ and ‘Email To Sms’. At the time of execution, the malware creates and runs both a legitimate tool and a malicious file, making it difficult for users to realize that a malicious activity has occurred. --------------------------------------------- https://asec.ahnlab.com/en/61584/ ===================== = Vulnerabilities = ===================== ∗∗∗ Request Tracker Write-up (CVE-2023-41259, CVE-2023-41260) ∗∗∗ --------------------------------------------- Without authentication we were able to extract file-attachments that were uploaded to RT, including e-mails received from and to users regarding tickets and issues. We also found it was possible to obtain information about tickets and users. --------------------------------------------- https://www.linkedin.com/pulse/request-tracker-write-up-tom-wolters-ygsae ∗∗∗ PowerDNS Security Advisory 2024-01: crafted DNSSEC records in a zone can lead to a denial of service in Recursor ∗∗∗ --------------------------------------------- An attacker can publish a zone that contains crafted DNSSEC related records. While validating results from queries to that zone using the RFC mandated algorithms, the Recursor’s resource usage can become so high that processing of other queries is impacted, resulting in a denial of service. Note that any resolver following the RFCs can be impacted, this is not a problem of this particular implementation. --------------------------------------------- https://doc.powerdns.com/recursor/security-advisories/powerdns-advisory-202… ∗∗∗ DNS-Server: Bind und Unbound stolpern über Sicherheitslücke "KeyTrap" ∗∗∗ --------------------------------------------- Mit einer präparierten DNS-Anfrage können Angreifer eine hohe Prozessorlast verursachen und den Dienst für legitime Nutzer so blockieren. Patches stehen bereit. --------------------------------------------- https://www.heise.de/-9627276 ∗∗∗ Sicherheitslücken: Angreifer können Dell Unity kompromittieren ∗∗∗ --------------------------------------------- Die Fehler stecken in Dell Unity Operating Enviroment (OE). Die Entwickler geben an, die Ausgabe 5.4.0.0.5.094 repariert zu haben. Von den Sicherheitsproblemen sind unter anderem Dell EMC Unity, Dell EMC Unity XT 380F und Dell EMC Unity Hybrid betroffen. Alle verwundbaren Produkte sind in der Warnmeldung aufgelistet. --------------------------------------------- https://www.heise.de/-9626407 ∗∗∗ Qnap: Sicherheitslücken in Firmware erlauben Einschleusen von Befehlen ∗∗∗ --------------------------------------------- In der Sicherheitswarnung schreibt Qnap, dass es sich um zwei Schwachstellen handelt. Die Beschreibung für beide lautet: Eine Befehlsschmuggel-Schwachstelle wurde in mehreren Qnap-Betriebssystemversionen gemeldet. Sofern sie missbraucht werden, erlauben sie Nutzern, Befehle über das Netzwerk auszuführen (CVE-2023-47218, CVE-2023-50358, CVSS 5.8, Risiko "mittel"). --------------------------------------------- https://www.heise.de/-9626319 ∗∗∗ SAP patcht: 13 Sicherheitslücken abgedichtet ∗∗∗ --------------------------------------------- SAP verteilt Software-Updates, die Schwachstellen aus 13 Sicherheitsmitteilungen ausbessern.

Bedrohungsakteure, die im Rahmen ihrer Angriffe Lockbit 3.0 einsetzen erlangen vor allem über den Missbrauch von RDP-Verbindungen (beispielsweise unter Einsatz anderweitig gestohlener Zugangsdaten) und die Ausnutzung von Schwachstellen in aus dem Internet erreichbaren Applikationen Zugang zu den Netzwerken ihrer Opfer.
