===================== = End-of-Day report = ===================== Timeframe: Montag 29-11-2021 18:00 − Dienstag 30-11-2021 18:00 Handler: Thomas Pribitzer Co-Handler: Stephan Richter ===================== = News = ===================== ∗∗∗ Printing Shellz: Sicherheitslücken in HP-Druckern/-Multifunktionsgeräten ∗∗∗ --------------------------------------------- Passend zum 30. November, dem Computer Security Day habe ich noch was. Es gibt eine Sicherheitslücke in der Firmware bestimmter HP LaserJet, HP LaserJet Managed, HP PageWide und HP PageWide Managed Produkte. Diese sind möglicherweise für einen Pufferüberlauf anfällig. Das bedeutet, Angreifer könnten Druckaufträge oder Scans abfangen und ggf. die Firmennetzwerke lahmlegen. --------------------------------------------- https://www.borncity.com/blog/2021/11/30/printing-shellz-sicherheitslcken-i… ∗∗∗ Gefälschtes BAWAG SMS im Umlauf ∗∗∗ --------------------------------------------- Momentan kursieren gefälschte SMS-Nachrichten im Namen der BAWAG.

Many of them didn’t understand the importance of a password’s character strength, or how frequent attacks on “root” are as a username, including myself at one point in time. I’ve learned more about SSH Brute Force attacks throughout my years at Sucuri. --------------------------------------------- https://blog.sucuri.net/2021/11/what-weve-learned-about-ssh-brute-force-att… ∗∗∗ 300.000+ infections via Droppers on Google Play Store ∗∗∗ --------------------------------------------- In this blog we will discuss the recent techniques used to spread Android banking trojans via Google Play (MITRE T1475) resulting in significant financial loss for targeted banks. We will also discuss the, sometimes forgotten, by-product of collecting contacts and keystrokes by Banking trojans, resulting in severe data leakage. --------------------------------------------- https://www.threatfabric.com/blogs/deceive-the-heavens-to-cross-the-sea.html ∗∗∗ Sabbath Ransomware Operators Target Critical Infrastructure ∗∗∗ --------------------------------------------- Since June 2021, a relatively new ransomware group called Sabbath has been targeting critical infrastructure in the United States and Canada, including education, health and natural resources. --------------------------------------------- https://www.securityweek.com/sabbath-ransomware-operators-target-critical-i… ∗∗∗ Yanluowang: Further Insights on New Ransomware Threat ∗∗∗ --------------------------------------------- At least one attacker now using Yanluowang may have previously been linked to Thieflock ransomware operation. --------------------------------------------- https://symantec-enterprise-blogs.security.com/blogs/threat-intelligence/ya… ∗∗∗ Kernel Karnage – Part 5 (I/O & Callbacks) ∗∗∗ --------------------------------------------- After showing interceptor’s options, it’s time to continue coding!

===================== = End-of-Day report = ===================== Timeframe: Freitag 19-11-2021 18:00 − Montag 22-11-2021 18:00 Handler: Wolfgang Menezes Co-Handler: Robert Waldner ===================== = News = ===================== ∗∗∗ Picky PPID Spoofing ∗∗∗ --------------------------------------------- Parent Process ID (PPID) Spoofing is one of the techniques employed by malware authors to blend in the target system. This is done by making the malicious process look like it was spawned by another process. This helps evade detections that are based on anomalous parent-child process relationships. --------------------------------------------- https://captmeelo.com/redteam/maldev/2021/11/22/picky-ppid-spoofing.html ∗∗∗ Command injection prevention for Python ∗∗∗ --------------------------------------------- This is a command/code injection prevention cheat sheet by r2c. It contains code patterns of potential ways to run an OS command or arbitrary code in an application. Instead of scrutinizing code for exploitable vulnerabilities, the recommendations in this cheat sheet pave a safe road for developers that mitigates the possibility of command/code injection in your code. --------------------------------------------- https://semgrep.dev/docs/cheat-sheets/python-command-injection/ ∗∗∗ Missing Link: Wie sicher ist der Anonymisierungsdienst Tor? ∗∗∗ --------------------------------------------- Tor gilt als Wunderwaffe gegen den Überwachungswahn von Geheimdiensten.

(arXiv:2111.10167v1 [cs.SE]) ∗∗∗ --------------------------------------------- This paper introduces Amaranth project - a solution to some of the contemporary security issues related to UEFI firmware. In this work we focused our attention on virtual machines as it allowed us to simplify the development of secure UEFI firmware. Security hardening of our firmware is achieved through several techniques, the most important of which are an operating system integrity checking mechanism (through snapshots) and overall firmware size reduction. --------------------------------------------- http://arxiv.org/abs/2111.10167 ∗∗∗ Oh ...

Das heisst, es sind nicht einzelne Clients, Workstations oder Server auf Windows Betriebsystem-Ebene, sondern alle Maschinen, die virtualisiert - auf zum Beispiel VMware ESXi oder Microsoft Hyper-V - laufen, gleichzeitig betroffen.

Part II: Securely Isolate Network Resources examines threats to 5G container-centric or hybrid container/virtual network, also known as Pods. The guidance provides several aspects of pod security including limiting permissions on deployed containers, avoiding resource contention and denial-of-service attacks, and implementing real-time threat detection. --------------------------------------------- https://us-cert.cisa.gov/ncas/current-activity/2021/11/19/nsa-and-cisa-rele… ===================== = Vulnerabilities = ===================== ∗∗∗ Vulnerability Spotlight: Multiple vulnerabilities in Advantech R-SeeNet ∗∗∗ --------------------------------------------- R-SeeNet is the software system used for monitoring Advantech routers.
