===================== = End-of-Day report = ===================== Timeframe: Mittwoch 13-12-2023 18:00 − Donnerstag 14-12-2023 18:00 Handler: Thomas Pribitzer Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ Urteil des EuGH: Datenleck-Betroffene könnten doch Schadensersatz bekommen ∗∗∗ --------------------------------------------- Der Europäische Gerichtshof (EuGH) hat in einem neuen Urteil die Rechte der Betroffenen von Datenlecks gestärkt. Schon der Umstand, "dass eine betroffene Person infolge eines Verstoßes gegen die DSGVO befürchtet, dass ihre personenbezogenen Daten durch Dritte missbräuchlich verwendet werden könnten, kann einen 'immateriellen Schaden' darstellen", heißt es in dem Urteil, das am 14. Dezember 2023 veröffentlicht wurde. --------------------------------------------- https://www.golem.de/news/urteil-des-eugh-datenleck-betroffene-koennten-doc… ∗∗∗ Reverse, Reveal, Recover: Windows Defender Quarantine Forensics ∗∗∗ --------------------------------------------- Windows Defender (the antivirus shipped with standard installations of Windows) places malicious files into quarantine upon detection. Reverse engineering mpengine.dll resulted in finding previously undocumented metadata in the Windows Defender quarantine folder that can be used for digital forensics and incident response. Existing scripts that extract quarantined files do not process this metadata, even though it could be useful for analysis. Fox-IT’s open-source digital forensics and incident response framework Dissect can now recover this metadata, in addition to recovering quarantined files from the Windows Defender quarantine folder. --------------------------------------------- https://blog.fox-it.com/2023/12/14/reverse-reveal-recover-windows-defender-… ∗∗∗ Mobile Sicherheit. Handlungsempfehlungen und präventive Maßnahmen für die sichere Nutzung von mobilen Endgeräten, 2023 ∗∗∗ --------------------------------------------- Wie so oft stehen aber auch in diesem Bereich Komfort und Sicherheit in einem permanenten Spannungsverhältnis. Ein Mehr an Sicherheit für Ihr Gerät und Ihre Daten kann auf der anderen Seite bedeuten, dass einige durchaus praktische Funktionen nur mehr eingeschränkt oder gar nicht mehr zur Verfügung stehen. Letztlich liegt es an Ihnen, den für Sie bestmöglichen Kompromiss zwischen Funktion, Komfort, Sicherheit und Privatsphäre zu finden. Die vorliegende Broschüre möchte Ihnen dabei helfen. --------------------------------------------- https://www.nis.gv.at/dam/jcr:8165f553-2769-4553-91c8-4b117c752f56/mobile_s… ∗∗∗ Ransomware: AlphV meldet sich zurück, Aufruhr in der Szene ∗∗∗ --------------------------------------------- In der Ransomware-Szene rumort es: Gruppen versuchen, einander Mitglieder abspenstig zu machen, ein Geldwäscher geht ins Netz und Betrüger betrügen einander. --------------------------------------------- https://www.heise.de/-9574446 ∗∗∗ Amazon-Händler:innen wollen über Telegram-Gruppen Bewertungen kaufen? Machen Sie nicht mit! ∗∗∗ --------------------------------------------- Auf Telegram gibt es Kanäle, die gratis Amazon-Produkte versprechen. Die Idee dahinter: Sie suchen sich ein Produkt aus, bestellen es über Ihren privaten Amazon-Account, schreiben eine 5-Sterne-Bewertung und bekommen als Dankeschön das Geld über PayPal zurückerstattet. Mit dieser Masche kaufen sich Marketplace-Händler:innen Bewertungen, um besser gerankt zu werden – eine nicht legale Praktik. --------------------------------------------- https://www.watchlist-internet.at/news/amazon-haendlerinnen-wollen-ueber-te… ∗∗∗ Protecting the enterprise from dark web password leaks ∗∗∗ --------------------------------------------- The trade in compromised passwords in dark web markets is particularly damaging. Cybercriminals often exploit password leaks to access sensitive data, commit fraud or launch further attacks. Let’s explore the various ways passwords are leaked to the dark web and discuss strategies for using dark web data to protect your organization. --------------------------------------------- https://cybersecurity.att.com/blogs/security-essentials/protecting-the-ente… ∗∗∗ Rhadamanthys v0.5.0 – a deep dive into the stealer’s components ∗∗∗ --------------------------------------------- In this article we do a deep dive into the functionality and cooperation between the modules.

More often than not, these tokens are leaked somewhere. When these tokens are exfiltrated during a Red Team exercise, it can be a pain to properly utilize them. Now EvilSlackbot is here to automate and streamline that process. You can use EvilSlackbot to send spoofed Slack messages, phishing links, files, and search for secrets leaked in slack. [..] In addition to red teaming, EvilSlackbot has also been developed with Slack phishing simulations in mind. --------------------------------------------- https://github.com/Drew-Sec/EvilSlackbot ∗∗∗ Scans for ownCloud Vulnerability (CVE-2023-49103), (Mon, Nov 27th) ∗∗∗ --------------------------------------------- Last week, ownCloud released an advisory disclosing a new vulnerability, CVE-2023-49103 [1]. The vulnerability will allow attackers to gain access to admin passwords. To exploit the vulnerability, the attacker will use the "graphapi" app to access the output of "phpinfo".

===================== = End-of-Day report = ===================== Timeframe: Montag 13-11-2023 18:00 − Dienstag 14-11-2023 18:00 Handler: Stephan Richter Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ CISA warns of actively exploited Juniper pre-auth RCE exploit chain ∗∗∗ --------------------------------------------- CISA warned federal agencies today to secure Juniper devices on their networks by Friday against four vulnerabilities now used in remote code execution (RCE) attacks as part of a pre-auth exploit chain. The alert comes one week after Juniper updated its advisory to notify customers that the flaws found in Juniper's J-Web interface (tracked as CVE-2023-36844, CVE-2023-36845, CVE-2023-36846, and CVE-2023-36847) have been successfully exploited in the wild. --------------------------------------------- https://www.bleepingcomputer.com/news/security/cisa-warns-of-actively-explo… ∗∗∗ ChatGPT, Bard und andere: KI-Systeme ermöglichen Ausleiten von Daten ∗∗∗ --------------------------------------------- Durch gezielte Abfragen lassen sich private und geschützte Daten aus KI-Systemen ausleiten.

Some of them can be noticed because they perform DNS lookup and some of them initiates connection without DNS lookup. For this last option, this is abnormal and can be noticed by any Network Detection and Response (NDR) tool that reviews the network traffic by at least two weeks. Most companies do not have money to afford a NDR, so I'm going to show you today an interesting tip that have worked for me to notice APT calling home when they perform DNS lookup. --------------------------------------------- https://isc.sans.edu/diary/rss/30396 ∗∗∗ Bug hunters on your marks: TETRA radio encryption algorithms to enter public domain ∗∗∗ --------------------------------------------- The algorithms are used by TETRA – short for the Terrestrial Trunked Radio protocol – and they are operated by governments, law enforcement, military and emergency services organizations in Europe, the UK, and other countries. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2023/11/14/tetra_encryp… ∗∗∗ Novel backdoor persists even after critical Confluence vulnerability is patched ∗∗∗ --------------------------------------------- Got a Confluence server?

Python offers three libraries shipped with a standard installation for handling e-mail transfer. These modules are smtplib, imaplib, and poplib. While Python programming is usually straightforward, using these Python libraries require passing a magic parameter in the right way to use secure communication. --------------------------------------------- https://www.pentagrid.ch/en/blog/python-mail-libraries-certificate-verifica… ∗∗∗ LockBit ransomware group assemble strike team to breach banks, law firms and governments. ∗∗∗ --------------------------------------------- [...] I thought it would be good to break down what is happening and how they’re doing it, since LockBit are breaching some of the world’s largest organisations - many of whom have incredibly large security budgets. Through data allowing the tracking of ransomware operators, it has been possible to track individual targets. Recently, it has become clear they have been targeting a vulnerability in Citrix Netscaler, called CitrixBleed. --------------------------------------------- https://doublepulsar.com/lockbit-ransomware-group-assemble-strike-team-to-b… ∗∗∗ CVE Half-Day Watcher ∗∗∗ --------------------------------------------- CVE Half-Day Watcher is a security tool designed to highlight the risk of early exposure of Common Vulnerabilities and Exposures (CVEs) in the public domain. It leverages the National Vulnerability Database (NVD) API to identify recently published CVEs with GitHub references before an official patch is released. By doing so, CVE Half-Day Watcher aims to underscore the window of opportunity for attackers to "harvest" this information and develop exploits. --------------------------------------------- https://github.com/Aqua-Nautilus/CVE-Half-Day-Watcher ∗∗∗ Vorsicht vor Jobangeboten per SMS oder WhatsApp ∗∗∗ --------------------------------------------- Unerwartet erhalten Sie eine Nachricht von einer Personalvermittlungsagentur: Ihnen wird ein Job angeboten.

The attack can be launched as long as the victim opens an .accdb or .mdb file. In fact, any more-common Office file type (such as a .rtf ) can work as well 4. This technique allows the attacker to bypass existing Firewall rules designed to block NTLM information stealing initiated by external attacks. --------------------------------------------- https://research.checkpoint.com/2023/abusing-microsoft-access-linked-table-… ∗∗∗ Bericht: IT-Sicherheit in Gesundheitsämtern vernachlässigt ∗∗∗ --------------------------------------------- Fehlendes Know-How, knappes Budget und unsichere Software.

Diese wurden im September 2023 an Microsoft gemeldet und ZDI stuft die mit CVSS-Scores von 7.1 bis 7.5 ein. Microsofts Sicherheitsexperten sehen die Schwachstellen als nicht so schwerwiegend an, dass diese ein sofortiges Handeln erfordern (zur Ausnutzung sei eine Authentifizierung erforderlich). Die Microsoft-Entwickler haben Fixes "für später" angekündigt. Daher ist die Zero Day Initiative an die Öffentlichkeit gegangen, da man trotzdem die Möglichkeit für RCE-Angriffe und Datenklau sieht. --------------------------------------------- https://www.borncity.com/blog/2023/11/04/microsoft-exchange-vier-0-day-schw… ∗∗∗ Sicherheitsupdates QNAP: Angreifer können eigene Befehle auf NAS ausführen ∗∗∗ --------------------------------------------- Wichtige Sicherheitspatches sichern Netzwerkspeicher von QNAP ab.

The threat actor is distributing a legitimate EXE file with a valid signature and a malicious DLL compressed in the same directory. The EXE file itself is legitimate, but when executed in the same directory as the malicious DLL, it automatically runs that malicious DLL. This technique is called DLL hijacking and is often used in the distribution of malware. --------------------------------------------- https://asec.ahnlab.com/en/58319/ ∗∗∗ Attackers use JavaScript URLs, API forms and more to scam users in popular online game “Roblox” ∗∗∗ --------------------------------------------- Where there is a potential for profit there are also people trying to scam others. “Roblox” users can be targeted by scammers (known as “beamers” by “Roblox” players) who attempt to steal valuable items or Robux from other players. This can sometimes be made easier for the scammers because of “Roblox's” young user base. Nearly half of the game’s 65 million users are under the age of 13 who may not be as adept at spotting scams. --------------------------------------------- https://blog.talosintelligence.com/roblox-scam-overview/ ∗∗∗ Suspected Exploitation of Apache ActiveMQ CVE-2023-46604 ∗∗∗ --------------------------------------------- Beginning Friday, October 27, Rapid7 Managed Detection and Response (MDR) identified suspected exploitation of Apache ActiveMQ CVE-2023-46604 in two different customer environments. In both instances, the adversary attempted to deploy ransomware binaries on target systems in an effort to ransom the victim organizations. Based on the ransom note and available evidence, we attribute the activity to the HelloKitty ransomware family, whose source code was leaked on a forum in early October. Rapid7 observed similar indicators of compromise across the affected customer environments, both of which were running outdated versions of Apache ActiveMQ. --------------------------------------------- https://www.rapid7.com/blog/post/2023/11/01/etr-suspected-exploitation-of-a… ===================== = Vulnerabilities = ===================== ∗∗∗ Unpatched Powerful SSRF in Exchange OWA – Getting Response Through Attachments ∗∗∗ --------------------------------------------- As the attacker can abuse this SSRF to retrieve the content of the response, I thought it was a good finding.

===================== = End-of-Day report = ===================== Timeframe: Montag 30-10-2023 18:00 − Dienstag 31-10-2023 18:00 Handler: Michael Schlagenhaufer Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ CVE-2023-4966 in Citrix NetScaler ADC und NetScaler Gateway wurde bereits als 0-day ausgenutzt ∗∗∗ --------------------------------------------- Uns wurde inzwischen von drei Organisationen in Österreich berichtet, dass Angreifer aufgrund der Sicherheitslücke im Citrix Server in ihren Systemen aktiv geworden sind, bevor Patches von Citrix verfügbar waren. Es wurden Befehle zur Erkundung des Systems und erste Schritte in Richtung lateral Movement beobachtet. Wir gehen inzwischen von einer weitläufigen Ausnutzung dieses 0-days aus. --------------------------------------------- https://cert.at/de/aktuelles/2023/10/cve-2023-4966-0day ∗∗∗ Exploit für Cisco IOS XE veröffentlicht, Infektionszahlen weiter hoch ∗∗∗ --------------------------------------------- Sicherheitsforscher haben den Exploit für Cisco IOS XE untersucht und seinen simplen Trick aufgedeckt. Hunderte Geräte mit Hintertür sind noch online. --------------------------------------------- https://www.heise.de/-9349296 ∗∗∗ Multiple Layers of Anti-Sandboxing Techniques, (Tue, Oct 31st) ∗∗∗ --------------------------------------------- It has been a while that I did not find an interesting malicious Python script. All the scripts that I recently spotted were always the same: a classic intostealer using Discord as C2 channel. Today I found one that contains a lot of anti-sanboxing techniques. Let's review them. For malware, it's key to detect the environment where they are executed. When detonated inside a sandbox (automatically or, manually, by an Analyst), they will be able to change their behaviour (most likely, do nothing). --------------------------------------------- https://isc.sans.edu/diary/rss/30362 ∗∗∗ Malicious NuGet Packages Caught Distributing SeroXen RAT Malware ∗∗∗ --------------------------------------------- Cybersecurity researchers have uncovered a new set of malicious packages published to the NuGet package manager using a lesser-known method for malware deployment. --------------------------------------------- https://thehackernews.com/2023/10/malicious-nuget-packages-caught.html ∗∗∗ LDAP authentication in Active Directory environments ∗∗∗ --------------------------------------------- Understanding the different types of LDAP authentication methods is fundamental to apprehend subjects such as relay attacks or countermeasures.

Not only is Kazuar another name for the enormous and dangerous cassowary bird, Kazuar is an advanced and stealthy .NET backdoor that Pensive Ursa usually uses as a second stage payload. --------------------------------------------- https://unit42.paloaltonetworks.com/pensive-ursa-uses-upgraded-kazuar-backd… ===================== = Vulnerabilities = ===================== ∗∗∗ Kritische Sicherheitslücke in Confluence Data Center und Confluence Server ∗∗∗ --------------------------------------------- In allen Versionen von Confluence Data Center und Confluence Server existiert eine kritische Sicherheitslücke (CVE-2023-22518 CVSS: 9.1). Das Ausnutzen der Sicherheitslücke auf betroffenen Geräten ermöglicht nicht authentifizierten Angreifern den Zugriff auf interne Daten des Systems. Obwohl Atlassian bislang keine Informationen zur aktiven Ausnutzung der Lücke hat, wird das zeitnahe Einspielen der verfügbaren Patches empfohlen. --------------------------------------------- https://cert.at/de/warnungen/2023/10/confluence-cve-2023-22518 ∗∗∗ RCE exploit for Wyze Cam v3 publicly released, patch now ∗∗∗ --------------------------------------------- A security researcher has published a proof-of-concept (PoC) exploit for Wyze Cam v3 devices that opens a reverse shell and allows the takeover of vulnerable devices [...] Wyze released firmware update version 4.36.11.7071, which addresses the identified issues, on October 22, 2023, so users are recommended to apply the security update as soon as possible. --------------------------------------------- https://www.bleepingcomputer.com/news/security/rce-exploit-for-wyze-cam-v3-… ∗∗∗ Unpatched NGINX ingress controller bugs can be abused to steal Kubernetes cluster secrets ∗∗∗ --------------------------------------------- Three unpatched high-severity bugs in the NGINX ingress controller can be abused by miscreants to steal credentials and other secrets from Kubernetes clusters. The vulnerabilities, tracked as CVE-2023-5043, CVE-2023-5044 and CVE-2022-4886, were disclosed on October 27, and are listed as currently awaiting triage.

With the default configuration of these printers, it’s possible to retrieve these credentials in an encrypted format without authenticating to the printer. A vulnerability in the encryption process of these credentials means that you can decrypt them with responses from the web interface.

During a lengthy outage, I decided to redo some of my network configurations. As part of this change, I also reorganized my IPv6 setup, relying more on DHCPv6 and less on router advertisements to configure IPv6 addresses. Overall, this worked well. My Macs had no issues connecting to IPv6. However, the Linux host I use to alert me of network connectivity issues could not "ping" the test host via IPv6. --------------------------------------------- https://isc.sans.edu/diary/rss/30336 ∗∗∗ Tampered OpenCart Authentication Aids Credit Card Skimming Attack ∗∗∗ --------------------------------------------- Using out of date software is the leading cause of website compromise, so keeping your environment patched and up to date is one of the most important responsibilities of a website administrator. It’s not uncommon to employ the use of custom code on websites, and spend small fortunes on software developers to tailor their website just the way they want it. However, the usage of customised code can sometimes inadvertently lock a website administrator into using an out of date CMS installation long after its expiry date, particularly if they no longer have access to their old developer (or sufficient funds to hire a new one). --------------------------------------------- https://blog.sucuri.net/2023/10/tampered-opencart-authentication-aids-credi… ∗∗∗ Abusing gdb Features for Data Ingress & Egress ∗∗∗ --------------------------------------------- As of November 2019, elfutils supports debuginfod, a client/server protocol that enables debuggers (gdb) to fetch debugging symbols via HTTP/HTTPs from a user-specified remote server. This blog post will demonstrate how this feature of gdb can be abused to create data communication paths for data exfiltration and tool ingress. --------------------------------------------- https://www.archcloudlabs.com/projects/debuginfod/ ∗∗∗ Vorsicht vor Jobangeboten auf WhatsApp oder Telegram ∗∗∗ --------------------------------------------- Sie suchen gerade einen Job? Praktisch, wenn Sie gar nicht suchen müssen und Sie direkt auf WhatsApp oder Telegram einen Job angeboten bekommen. Dahinter stecken aber Kriminelle, die Ihnen z.

Oktober 2023 Cisco hat für einige der von der Schwachstelle betroffenen Geräte Aktualisierungen veröffentlicht, und weitere Updates angekündigt. Das Unternehmen aktualisiert die Liste an verfügbaren Patches auf einer dedizierten Seite laufend. Wenn das Management-WebInterface eines Cisco XE Gerätes vor dem Einspielen des Updates offen im Netz erreichbar war, ist davon auszugehen, dass ein Angreifer dies ausgenutzt hat und zumindest neue Admin-Accounts angelegt hat.

A good example of these is the device class of ‘next generation’ firewalls, which usually include VPN termination functionality (meaning they’re Internet-accessible by network design).
