∗∗∗ DTrack activity targeting Europe and Latin America ∗∗∗
---------------------------------------------
DTrack is a backdoor used by the Lazarus group. Initially discovered in 2019, the backdoor remains in use three years later. It is used by the Lazarus group against a wide variety of targets. [..] So, what’s new? DTrack itself hasn’t changed much over the course of time. Nevertheless, there are some interesting modifications that we want to highlight in this blogpost. Dtrack hides itself inside an executable that looks like a legitimate program, and there are several stages of decryption before the malware payload starts.

∗∗∗ ABI compatibility in Python: How hard could it be? ∗∗∗
---------------------------------------------
This post will cover just one tiny piece of Python packaging’s complexity: the CPython stable ABI. We’ll see what the stable ABI is, why it exists, how it’s integrated into Python packaging, and how each piece goes terribly wrong to make accidental ABI violations easy.

∗∗∗ Checkmk: Remote Code Execution by Chaining Multiple Bugs ∗∗∗
---------------------------------------------
Within the series of articles, we take a detailed look at multiple vulnerabilities we identified in Checkmk and its NagVis integration, which can be chained together by an unauthenticated, remote attacker to fully take over the server running a vulnerable version of Checkmk.

∗∗∗ Organizations Warned of Critical Vulnerability in Backstage Developer Portal Platform ∗∗∗
---------------------------------------------
Backstage is affected by a critical vulnerability related to a security hole found earlier this year by Oxeye in the popular sandbox library VM2. The VM2 flaw, dubbed SandBreak and tracked as CVE-2022-36067, can allow a remote attacker to escape the sandbox and execute arbitrary code on the host.
Backstage has been using VM2 and Oxeye researchers discovered that CVE-2022-36067 can be exploited for unauthenticated remote code execution in Backstage by abusing its software templates.

∗∗∗ Android malware: A million people downloaded these malicious apps before they were finally removed from Google Play ∗∗∗
---------------------------------------------
Cybersecurity researchers identify an aggressive adware campaign. The developer is now banned from Google Play - but if youve not uninstalled the apps, youre still infected. [..] The four apps that have been identified as malicious were from a developer called Mobile apps Group and were called 'Bluetooth Auto Connect', 'Bluetooth App Sender', 'Mobile transfer: smart switch', and 'Driver: Bluetooth, Wi-Fi, USB'.

∗∗∗ LKA warnt vor Betrugsmasche mit digitalen Kreditkarten (Nov. 2022) ∗∗∗
---------------------------------------------
Das LKA Niedersachsen warnt vor einer neue Betrugsmasche, die Cyber-Kriminelle erdacht haben. Mittels Phishing-E-Mails, gefälschten Webseiten und digitalen Kreditkarten versuchen sie an Zahlungsdaten der Opfer heranzukommen. Die Daten der digitalen Kreditkarte werden dann für eigene Einkäufe auf Kosten des Opfers missbraucht.
