Oracle databases, TNS, and how to hack it.

The Oracle Transparent Network Substrate (TNS) server is a communication protocol that enables communication between Oracle databases and applications across networks. Initially introduced as part of the Oracle Net Services software suite, TNS supports diverse networking protocols, including IPX/SPX and TCP/IP protocol stacks, facilitating communication between Oracle databases and client applications. Its built-in encryption mechanism ensures the security of data transmitted. Over time, TNS has undergone updates to support newer technologies, including IPv6 and SSL/TLS encryption.

You’ve been dragged through hell and emerged bruised and battered. Now how do you conduct an effective post-incident review?

When an incident occurs—whether it’s a security breach, a system outage, or a critical business disruption—the immediate priority is resolution. But once the dust settles, the real opportunity lies in learning from the event to strengthen your organization’s resilience. Conducting an effective post-incident review (PIR) is essential for continuous improvement, risk mitigation, and fostering a culture of transparency and trust.

Powerful prompt engineering techniques for LLM hacking – how Large Language Models are hacked.

As Large Language Models (LLMs) such as ChatGPT, Perplexity, and Gemini become more prevalent, hackers are, of course, finding ingenious ways to hack them. They succeed because LLMs struggle to distinguish between legitimate instructions and adversarial inputs. Sure, they have some defenses, including input sanitization, output filtering, and adversarial training, but thus far, no foolproof solution exists to stop a hacker from tricking an LLM into doing what they want.
