He introduces the "coffee shop test" as a way to help you overcome nerves, connect with your audience and deliver a message that truly resonates. After the talk, Modupe explains a similar approach in academia called the "Grandma test," and how public speaking can be as simple as a conversation with grandma.

SANS Stormcast Tuesday, April 22nd: Phishing via Google; ChatGPT Fingerprint; Asus AI Cloud Vuln; PyTorch RCE It's 2025, so why are malicious advertising URLs still going strong? Phishing attacks continue to take advantage of Google’s advertising services. Sadly, this is still the case for obviously malicious links, even after various anti-phishing services flag the URL. https://isc.sans.edu/diary/It%27s%202025...%20so%20why%20are%20obviously%20malicious%20advertising%20URLs%20still%20going%20strong%3F/31880 ChatGPT Fingerprinting Documents via Unicode ChatGPT apparently started leaving fingerprints in texts, which it creates by adding invisible Unicode characters like non-breaking spaces. https://www.rumidocs.com/newsroom/new-chatgpt-models-seem-to-leave-watermarks-on-text Asus AI Cloud Security Advisory Asus warns of a remote code execution vulnerability in its routers. The vulnerability is related to the AI Cloud feature. If your router is EoL, disabling the feature will mitigate the vulnerability https://www.asus.com/content/asus-product-security-advisory/ PyTorch Vulnerability PyTorch fixed a remote code execution vulnerability exploitable if a malicious model was loaded. This issue was exploitable even with the “weight_only=True" setting selected https://github.com/pytorch/pytorch/security/advisories/GHSA-53q9-r3pm-6pq6 keywords: pytorch; ai cloud; asus; phishing; google

The backdoor is implemented via an SSH configuration file that instructs the SSH client to connect to a remote system and forward a shell on a random port. This will make the shell accessible to anybody able to connect to the C2 host. https://isc.sans.edu/diary/Simple%20SSH%20Backdoor/32000 Google Chrome to Distrust CAs Google Chrome will remove the Chunghwa Telecom and Netlock certificate authorities from its list of trusted CAs.
