Living off the land attacks use existing Windows binaries instead of downloading specific attack tools. This post-compromise technique is very difficult to block. AppLocker isn't really designed to block these attacks because AppLocker by default does allow standard Windows binaries to run. --------------------------------------------- https://isc.sans.edu/diary/rss/26032 ∗∗∗ Weaponized RTF Document Generator & Mailer in PowerShell, (Fri, Apr 17th) ∗∗∗ --------------------------------------------- Another piece of malicious PowerShell script that I found while hunting. Like many malicious activities that occur in those days, it is related to the COVID19 pandemic. Its purpose of simple: It checks if Outlook is used by the victim and, if it's the case, it generates a malicious RTF document that is spread to all contacts extracted from Outlook. Let's have a look at it. --------------------------------------------- https://isc.sans.edu/diary/rss/26030 ∗∗∗ Excel Malspam: Password Protected ...

The malicious script loads the credit card stealing code from qr201346[.]pw and sends the stolen details to hxxps://gooogletagmanager[.]online/get.php. This approach is pretty typical for skimmers. However, we noticed one interesting feature of the script — instead of using one predefined domain, it generates domain names based on the current date. --------------------------------------------- https://blog.sucuri.net/2020/04/web-skimmer-with-a-domain-name-generator.ht… ∗∗∗ Continued Threat Actor Exploitation Post Pulse Secure VPN Patching ∗∗∗ --------------------------------------------- [...] This Alert provides an update to Cybersecurity and Infrastructure Security Agency (CISA) Alert AA20-010A: Continued Exploitation of Pulse Secure VPN Vulnerability, which advised organizations to immediately patch [...] --------------------------------------------- https://www.us-cert.gov/ncas/alerts/aa20-107a ∗∗∗ Sophos zieht problematisches Firmware-Update 9.703 für UTM zurück ∗∗∗ --------------------------------------------- Achtung, nicht installieren: Das Firmware-Update 9.703 für Sophos UTM-Appliances wurde vom Hersteller wegen gravierender Probleme wieder zurückgezogen. --------------------------------------------- https://heise.de/-4704634 ∗∗∗ New AgentTesla variant steals WiFi credentials ∗∗∗ --------------------------------------------- The popular infostealer AgentTesla recently added a new feature that can steal WiFi usernames and passwords, which can potentially be used to spread the malware. --------------------------------------------- https://blog.malwarebytes.com/threat-analysis/2020/04/new-agenttesla-varian… ===================== = Vulnerabilities = ===================== ∗∗∗ Apple Releases Security Update for Xcode ∗∗∗ --------------------------------------------- Apple has released a security update to address vulnerabilities in Xcode.
