---------------------------------------------
Real Quick In case you’re thrown by that fantastic title, our lawyers made us change the name of this project so we wouldn’t get sued. SCANdalous—a.k.a. Scannah Montana a.k.a. Scanny McScanface a.k.a. “Scan I Kick It? (Yes You Scan)”—had another name before today that, for legal reasons, we’re keeping to ourselves. A special thanks to our legal team who is always looking out for us, this blog post would be a lot less fun without them. Strap in folks.

Doch Vorsicht: Die bestellte Ware kommt nicht oder nur in minderwertiger Qualität an!

I get it. You dread going into the office sometimes. It isn’t that you don’t like the people or the location. It’s that beast, waiting for you when you arrive, and it never seems to go away. You work hard at it, but you never seem to get ahead.
You are responsible for the vulnerability management program within your organization. Either as part of a formal program or on an ad-hoc basis, it’s your baby. Except that it isn’t a baby, it is more of an untameable monster, a minotaur in the labyrinth, waiting to surprise you as you turn the corner.

∗∗∗ Dangerous Website Backups ∗∗∗
---------------------------------------------
It’s a well-known fact that website backups are important for mitigating a plethora of site issues. They can help restore a site after a compromise or even facilitate the investigative process by providing a clean code base to compare the current site state to. However, if a backup is not set up correctly, it can have the opposite effect — and may instead impose a security threat to your website.

---------------------------------------------
There are only a couple of default system-signed executables that let you download a file from a Web Server, and every security product and threat hunter specifically looks for them for signs of misuse or abuse by threat actors.

∗∗∗ Try2Cry: Ransomware tries to worm ∗∗∗

∗∗∗ Would you like some RCE with your Guacamole? ∗∗∗
---------------------------------------------
[...] Apache Guacamole is a popular infrastructure for remote work, with more than 10 Million docker downloads worldwide. In our research, we discovered that Apache Guacamole is vulnerable to several critical Reverse RDP Vulnerabilities, and is also impacted by a few new vulnerabilities found in FreeRDP. In short, these vulnerabilities allow an attacker, who has already successfully compromised a computer inside the organization, to launch an attack on the Guacamole gateway when an unsuspecting [...]

∗∗∗ A Second Look at CVE-2019-19781 (Citrix NetScaler / ADC) ∗∗∗
---------------------------------------------
In this blog post we will revisit CVE-2019-19781, a Remote Code Execution vulnerability affecting Citrix NetScaler / ADC. We will explore how this issue has been widely abused by various actors and how a hacker turf war led to some actors "adversary patching" the vulnerability in order to prevent secondary compromise by competing adversaries – hiding the true number of vulnerable and compromised devices in the wild.

Auch wenn der Online-Shop auf den ersten Blick vertrauenswürdig wirkt, sollten Sie hier lieber nichts bestellen. Die angegebenen Kontaktdaten existieren genauso wenig wie die Firma selbst.
