∗∗∗ Exploit released for critical VMware vRealize RCE vulnerability ∗∗∗
---------------------------------------------
Horizon3 security researchers have released proof-of-concept (PoC) code for a VMware vRealize Log Insight vulnerability chain that allows attackers to gain remote code execution on unpatched appliances.
VMware patched four security vulnerabilities in its vRealize log analysis tool last week, two being critical and allowing remote attackers to execute code on compromised devices.

∗∗∗ Decoding DNS over HTTP(s) Requests, (Mon, Jan 30th) ∗∗∗
---------------------------------------------
I have written before about scans for DNS over HTTP(s) (DoH) servers. DoH is now widely supported in different browsers and recursive resolvers. It has been an important piece in the puzzle to evade various censorship regimes, in particular, the "Big Chinese Firewall". Malware has at times used DoH, but often uses its own HTTP(s) based resolvers that do not necessarily comply with the official DoH standard.

∗∗∗ Abstandhalten zu undurchsichtigen Multi-Level-Marketing-Angeboten wie shopwithme.biz ∗∗∗
---------------------------------------------
Wer sich aktuell auf sozialen Medien wie Facebook, YouTube oder TikTok bewegt, kommt an Werbevideos, die das große Geld versprechen, kaum vorbei. Mit minimalem Aufwand und revolutionären Methoden sollen Sie ganz einfach Unsummen an Geld verdienen können. Ähnliches verspricht man beispielsweise bei shopwithme.biz. Ein genauerer Blick lässt vermuten: Hier verdient man nicht durch den Verkauf von Produkten, sondern durch die Anwerbung neuer Kundschaft. Wir raten hier
