===================== = 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? Listen up. Malware said to have wide-ranging capabilities.

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. Die Bezahlung ist gut und die Arbeitszeiten sind flexibel. Es geht darum, Hotels und Touristenattraktionen zu bewerten. Bei Interesse sollten Sie dem Arbeitgeber eine WhatsApp-Nachricht schicken. Ignorieren Sie dieses Jobangebot, es handelt sich um Betrug! --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-vor-jobangeboten-per-sms-od… ∗∗∗ Ddostf DDoS Bot Malware Attacking MySQL Servers ∗∗∗ --------------------------------------------- The ASEC analysis team has recently discovered that the Ddostf DDoS bot is being installed on vulnerable MySQL servers. Ddostf is a DDoS bot capable of conducting Distributed Denial of Service (DDoS) attacks on specific targets and was first identified around 2016. --------------------------------------------- https://asec.ahnlab.com/en/58878/ ∗∗∗ A Closer Look at ChatGPTs Role in Automated Malware Creation ∗∗∗ --------------------------------------------- This blog entry explores the effectiveness of ChatGPTs safety measures, the potential for AI technologies to be misused by criminal actors, and the limitations of current AI models. --------------------------------------------- https://www.trendmicro.com/en_us/research/23/k/a-closer-look-at-chatgpt-s-r… ∗∗∗ Malicious Abrax666 AI Chatbot Exposed as Potential Scam ∗∗∗ --------------------------------------------- As of now, based on the information regarding the sale of the Abrax666 AI Chatbot, cybersecurity researchers are of the opinion that the chatbot is most likely a scam. --------------------------------------------- https://www.hackread.com/abrax666-ai-chatbot-exposed-as-potential-scam/ ===================== = Vulnerabilities = ===================== ∗∗∗ Siemens Security Advisories ∗∗∗ --------------------------------------------- Siemens has released 14 new and 18 updated Security Advisories. --------------------------------------------- https://www.siemens.com/global/en/products/services/cert.html?d=2023-11#Sie… ∗∗∗ Xen Security Advisory CVE-2023-46835 / XSA-445 - x86/AMD: mismatch in IOMMU quarantine page table levels ∗∗∗ --------------------------------------------- A device in quarantine mode can access data from previous quarantine page table usages, possibly leaking data used by previous domains that also had the device assigned. --------------------------------------------- https://xenbits.xen.org/xsa/advisory-445.html ∗∗∗ Xen Security Advisory CVE-2023-46836 / XSA-446 - x86: BTC/SRSO fixes not fully effective ∗∗∗ --------------------------------------------- An attacker in a PV guest might be able to infer the contents of memory belonging to other guests. --------------------------------------------- https://xenbits.xen.org/xsa/advisory-446.html ∗∗∗ SAP Security Patch Day –November2023 ∗∗∗ --------------------------------------------- On 14th of November 2023, SAP Security Patch Day saw the release of 3 new Security Notes.

Microsoft Access (part of the Office suite) has a “linking to remote SQL Server tables” feature. 2. This feature can be abused by attackers to automatically leak the Windows user’s NTLM tokens to any attacker-controlled server, via any TCP port, such as port 80. 3. 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.

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. However, Microsoft did not agree [...] In short: this may get fixed or it may not. If they decide to fix it, the patch may appear in 1 year or in 3 years. In general, we know nothing. Accordingly, we informed Microsoft of our intention to publish this vulnerability as a 0-day advisory and a blog post. As we consider this issue potentially dangerous, we want organizations to be aware of the threat. For this reason, we are providing a PoC HTTP Request to be used for filtering and/or monitoring. --------------------------------------------- https://www.thezdi.com/blog/2023/11/1/unpatched-powerful-ssrf-in-exchange-o… ∗∗∗ Cisco Security Advisories ∗∗∗ --------------------------------------------- Cisco has released 24 new and 4 updated Security Advisories (2x Critical, 11x High, 15x Medium) --------------------------------------------- https://sec.cloudapps.cisco.com/security/center/Search.x?publicationTypeIDs… ∗∗∗ Critical PHPFox RCE Vulnerability Risked Social Networks ∗∗∗ --------------------------------------------- Heads up, phpFox users!
