These routers use MQTT to send messages to each other for coordination purposes. In the version I tested against, there was zero authentication on this - anyone on the local network is able to connect to the MQTT interface on a router and send commands. --------------------------------------------- https://mjg59.dreamwidth.org/56106.html ∗∗∗ Microsoft Exchange Server Vulnerabilities Mitigations – updated March 9, 2021 ∗∗∗ --------------------------------------------- Microsoft previously blogged our strong recommendation that customers upgrade their on-premises Exchange environments to the latest supported version. For customers that are not able to quickly apply updates, we are providing the following alternative mitigation techniques to help Microsoft Exchange customers who need more time to patch their deployments and are willing to make risk and service function trade-offs. These mitigations are not a remediation if your Exchange servers have already been compromised, nor are they full protection against attack. --------------------------------------------- https://msrc-blog.microsoft.com:443/2021/03/05/microsoft-exchange-server-vu… ∗∗∗ SharpRDP - PSExec without PSExec, PSRemoting without PowerShell, (Wed, Mar 10th) ∗∗∗ --------------------------------------------- With the amount of remediation folks have these days to catch malicious execution of powershell or the use of tools like psexec, red teams have to be asking themselves - what approach is next for lateral movement after you get that first foothold? --------------------------------------------- https://isc.sans.edu/diary/rss/27188 ∗∗∗ Researchers Unveil New Linux Malware Linked to Chinese Hackers ∗∗∗ --------------------------------------------- Dubbed "RedXOR" by Intezer, the backdoor masquerades as a polkit daemon, with similarities found between the malware and those previously associated with the Winnti Umbrella (or Axiom) threat group such as PWNLNX, XOR.DDOS and Groundhog. --------------------------------------------- https://thehackernews.com/2021/03/researchers-unveil-new-linux-malware.html ∗∗∗ Unpatched Flaws in Netgear Business Switches Expose Organizations to Attacks ∗∗∗ --------------------------------------------- Security researchers have identified multiple vulnerabilities in ProSAFE Plus JGS516PE and GS116Ev2 business switches from Netgear, the most severe of which could allow a remote, unauthenticated attacker to execute arbitrary code. --------------------------------------------- https://www.securityweek.com/unpatched-flaws-netgear-business-switches-expo… ∗∗∗ Targeted HelloKitty Ransomware Attack ∗∗∗ --------------------------------------------- SentinelOne has published a blog post analyzing the HelloKitty ransomware family, which was recently leveraged in a targeted attack against CD Projekt Red. HelloKitty appeared in late 2020 and is relatively rudimentary compared to other ransomware families. --------------------------------------------- https://exchange.xforce.ibmcloud.com/collection/78d773e3e014982f6b10f60ac70… ===================== = Vulnerabilities = ===================== ∗∗∗ Microsoft Patch Tuesday - March 2021 ∗∗∗ --------------------------------------------- In their March 2021 security updates, Microsoft list eighty-three CVE numbered vulnerabilities. Of those, ten are rated as Critical with the remainder being rated as Important. Aside from the already well publicized exploitation of the Exchange server vulnerabilities, an Internet Explorer vulnerability is reported as being exploited in the wild. --------------------------------------------- https://exchange.xforce.ibmcloud.com/collection/c82f6a928a7278759e5eec21b3e… ∗∗∗ Patchday Adobe: Schadcode-Lücken in Connect, Creative Cloud und Framemaker ∗∗∗ --------------------------------------------- Der Software-Hersteller Adobe hat in verschiedenen Anwendungen mehrere kritische Sicherheitslücken geschlossen. --------------------------------------------- https://heise.de/-5076338 ∗∗∗ Versionsverwaltung Git 2.30.2. behebt Sicherheitslücke beim Klonen ∗∗∗ --------------------------------------------- Die Schwachstelle ermöglicht unter bestimmten Umständen das Ausführen von Skripten beim Klonen von Repositories. --------------------------------------------- https://heise.de/-5076502 ∗∗∗ SAP-Patchday: Kritische Lücken aus SAP MII und NetWeaver AS für Java beseitigt ∗∗∗ --------------------------------------------- SAP hat unter anderem zwei Sicherheitslücken in Manufacturing Integration and Intelligence (MII) & NetWeaver AS JAVA mit CVSS-Scores nahe der 10 geschlossen. --------------------------------------------- https://heise.de/-5076543 ∗∗∗ Vulnerability Spotlight: Use-after-free vulnerability in 3MF Consortium lib3mf ∗∗∗ --------------------------------------------- 3MF Consortium’s lib3mf library is vulnerable to a use-after-free vulnerability that could allow an adversary to execute remote code on the victim machine. The lib3mf library is an open-source implementation of the 3MF file format and standard, mainly used for 3D-printing. An attacker could send a target a specially crafted file to create a use-after-free condition. ---------------------------------------------

From Egregor to Doppelpaymer to Ryuk, it continues to command headlines. Pandemic-fueled phishing scams, the lack of visibility across remote endpoints, and lax attitudes have been a boon for ransomware groups over the last year. Worst of all, ransomware no longer discriminates. It dominates small towns and municipal offices, video game makers, and shamelessly, healthcare organizations and school systems already pushed to the brink by the COVID-19 pandemic. The threat could still become more pervasive over the next two to three years, not because ransomware is effective in and of itself but because of other players in the game - insurance companies, brokers, and even attorneys - that continue to fan the flames. --------------------------------------------- https://www.securityweek.com/inside-ransomware-economy ∗∗∗ Einreiseanmeldung für Deutschland nicht über „digitale-einreiseanmeldung.de“ vornehmen ∗∗∗ --------------------------------------------- Die Corona-Pandemie erschwert die Einreise in andere Länder erheblich.
