∗∗∗ Brute-Force-Angriffe auf exponierte Systeme ∗∗∗ --------------------------------------------- Aktuell werden dem BSI verstärkt Brute-Force-Angriffe gegen Citrix Netscaler Gateways aus verschiedenen KRITIS-Sektoren sowie von internationalen Partnern gemeldet. [..] Die aktuellen Angriffe heben sich aktuell lediglich in ihrer berichteten Menge von üblichen Angriffen dieser Art heraus. [..] Als Ziel der Brute-Force-Angriffe werden in aktuellen Berichten zwar Citrix Gateways gemeldet. Jedoch ist diese Cyber-Sicherheitswarnung für alle exponierten Systeme, insbesondere VPN-Gateways, relevant. --------------------------------------------- https://www.bsi.bund.de/SharedDocs/Cybersicherheitswarnungen/DE/2024/2024-29...
∗∗∗ Stark gestiegenes Aufkommen an Microsoft Remote Desktop Protokoll (RDP) Scanning ∗∗∗ --------------------------------------------- Ein internationaler Partner (Shadowserver) verzeichnet seit Anfang Dezember ein weltweit sehr stark gestiegenes Aufkommen (x160) an RDP "Scanning" in Wellen [1]. Ob es nur um Ausforschen offener RDP-Ports geht oder bereits weitere Handlungen gesetzt werden, ist aktuell unbekannt. Der Fokus scheint nicht auf dem RDP Standard-Port 3389, sondern auf Port 1098 zu liegen. --------------------------------------------- https://www.cert.at/de/aktuelles/2024/12/stark-gestiegenes-aufkommen-an-micr...

∗∗∗ Ultralytics PyPI Package Compromised Through GitHub Actions Cache Poisoning ∗∗∗ --------------------------------------------- Over the weekend, the popular Ultralytics PyPI package was compromised in a supply chain attack that was detected following reports of a discrepancy between the library’s code on GitHub and the code that was published to PyPI for v8.3.41. --------------------------------------------- https://socket.dev/blog/ultralytics-pypi-package-compromised-through-github-...
∗∗∗ Malware trends: eBPF exploitation, malware configurations stored in unexpected places, and increased use of custom post-exploitation tools ∗∗∗ --------------------------------------------- An investigation into an information security incident has allowed virus analysts at Doctor Web to uncover an ongoing campaign that incorporates many modern trends employed by cybercriminals. A client approached Doctor Web after suspecting that their computer infrastructure had been compromised. While analyzing the client’s data, our virus analysts identified a number of similar cases, leading them to conclude that an active campaign was underway. --------------------------------------------- https://news.drweb.com/show/?i=14955&lng=en&c=9
∗∗∗ When User Input Lines Are Blurred: Indirect Prompt Injection Attack Vulnerabilities in AI LLMs ∗∗∗ --------------------------------------------- Indirect prompt attacks are when an LLM takes input from external sources but where an attacker gets to smuggle payloads (additional prompts!) into these external/side sources. These malicious additional prompts modify the overall prompt, breaking out of the data context as they are treated as instructions (they are additional prompts, commands, if you will) and, in turn, influence the initial user prompt provided together with the system prompt and with that, the subsequent actions and output. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/when-user-in...
∗∗∗ Inside Zloader’s Latest Trick: DNS Tunneling ∗∗∗ --------------------------------------------- Zloader (a.k.a. Terdot, DELoader, or Silent Night) is a modular Trojan based on the leaked Zeus source code that emerged in 2015. The malware was originally designed to facilitate banking fraud via Automated Clearing House (ACH) and wire transfers. However, similar to other malware families like Qakbot and Trickbot, Zloader has been repurposed for initial access, providing an entry point into corporate environments for the deployment of ransomware. --------------------------------------------- https://www.zscaler.com/blogs/security-research/inside-zloader-s-latest-tric...
∗∗∗ Mit dem Bumble-Date ins Theater? Vorsicht vor Betrug! ∗∗∗ --------------------------------------------- Sie haben auf Bumble jemanden kennengelernt?

Vorsicht, hinter dem vermeintlich perfekten Match stecken Kriminelle, die Sie in einen Fake-Shop locken. --------------------------------------------- https://www.watchlist-internet.at/news/mit-dem-bumble-date-ins-theater-vorsi...
∗∗∗ Studie gemeinsam mit dem BSI: IT-Sicherheit von smarten Heizkörperthermostaten ∗∗∗ --------------------------------------------- Certitude führte im Auftrag des Bundesministerium für Sicherheit in der Informationstechnik (BSI) die technische Sicherheitsprüfung von smarten Heizkörperthermostaten durch. Die aus diesem Projekt entstandene und heute veröffentlichte Studie zeigt auf, dass es insbesondere beim Umgang mit Schwachstellen Nachholbedarf gibt. --------------------------------------------- https://certitude.consulting/blog/de/bsi-studie-sicherheit-smarte-heizkorper...
∗∗∗ Full-Face Masks to Frustrate Identification ∗∗∗ --------------------------------------------- It’s a video of someone trying on a variety of printed full-face masks. They won’t fool anyone for long, but will survive casual scrutiny. And they’re cheap and easy to swap. --------------------------------------------- https://www.schneier.com/blog/archives/2024/12/full-face-masks-to-frustrate-...
