For example, you could track an attacker and wait for some access to the captured credentials in a phishing kit installed on a compromised server. You could deploy an EDR solution or an OSSEC agent that implements an FIM (File Integrity Monitoring). Upon a file change, an action can be triggered. Nice, but what if you would like a quick solution but agentless? --------------------------------------------- https://isc.sans.edu/diary/rss/29362 ∗∗∗ ChatGPT: Emerging AI Threat Landscape ∗∗∗ --------------------------------------------- ChatGPT is a prototype chatbot released by OpenAI.

The ransomware employed anti-analysis techniques consisting of API calls that would likely crash some sandboxes/automated analysis systems. The malware targets all drives identified on the machine and deletes itself after the encryption is complete. --------------------------------------------- https://resources.securityscorecard.com/research/bian-lian-deep-dive ∗∗∗ New Python-Based Backdoor Targeting VMware ESXi Servers ∗∗∗ --------------------------------------------- Security researchers with Juniper Networks’ Threat Labs warn of a new Python-based backdoor targeting VMware ESXi virtualization servers. The targeted servers were impacted by known security defects (such as CVE-2019-5544 and CVE-2020-3992) that were likely used for initial compromise, but what caught the researchers’ attention was the simplicity, persistence, and capabilities of the deployed backdoor. --------------------------------------------- https://www.securityweek.com/new-python-based-backdoor-targeting-vmware-esx… ∗∗∗ What’s My Name Again?

On some operating systems (most widely: Windows) this results in a denial of service when the affected process hangs. Policy processing being enabled on a publicly facing server is not considered to be a common setup. --------------------------------------------- https://www.openssl.org/news/secadv/20221213.txt ∗∗∗ Patchday SAP: 14 neue Sicherheitsmeldungen im Dezember ∗∗∗ --------------------------------------------- Zum Jahresende behandelt SAP in 14 Sicherheitsnotizen Schwachstellen in der Software des Unternehmens.

Impact: An unathenticated attacker can remotely reset the administrator password. Solution: Mitigation: The certificate is renewed by adjusting the hostname to an own customer-specific, so it does not contain the serial number.
