Tenable opens playground for generative AI cyber tools
The safety neighborhood is being invited to discover the potential of generative artificial intelligence (AI) to behave as a useful gizmo in its analysis efforts, with the discharge of a variety of prototype tools developed by Tenable, which at the moment are available to check out on Github.
In an accompanying report titled How generative AI is changing security research, the agency’s analysis group shares the way it has been experimenting with generative AI functions to create efficiencies in reverse engineering, code debugging, internet software safety and visibility into cloud-based tools.
Tenable, which describes itself as an “exposure management” firm, mentioned tools reminiscent of these based mostly on OpenAI’s latest generative pre-trained transformer model, GPT-4, probably now have skills on par with these of a “mid-level security researcher”.
But, as Tenable director of safety response and zero-day analysis Ray Carney defined within the report’s preamble, even OpenAI admits GPT-4 has related limitations to earlier GPT fashions, significantly round reliability and biases that come up because of the mannequin’s experiences, the way it was skilled, incomplete and imperfect coaching information, and cognitive biases among the many mannequin’s builders.
Added to this, he mentioned, one should contemplate the cognitive biases of the individuals querying the mannequin – asking the best questions turns into “the most critical factor” in how possible one is to obtain an accurate reply.
This, mentioned Carney, pertains to safety researchers, as a result of the function of such individuals is to supply well timed and correct information to decision-makers.
“In pursuit of this goal, the analyst must process and interpret collections of incomplete and ambiguous data in order to produce sound, well-founded analytical judgments,” he wrote. “Over the course of a few years, and plenty of failures, the analytical neighborhood has developed a set of tools generally known as ‘structured analytic techniques’ that assist to mitigate and minimise the chance of being incorrect, and keep away from ill-informed choices.
“The warnings posed by OpenAI in its announcement of GPT-4 make a strong argument for the application of these techniques,” continued Carney. “In reality, it is just via the applying of a majority of these methods that we are going to finally produce a well-refined dataset to coach future fashions within the cyber safety area.
“These types of techniques will also help researchers to ensure that they are tuning their prompts for those models – that they’re asking the right questions,” he mentioned. “In the meantime, security researchers can continue to investigate how we leverage generative AI capabilities for more mundane tasks in order to free up time for researchers and analysts to invest their time on the more difficult questions that require their subject matter expertise to tease out critical context.”
The first software they got here up with is named G-3PO. This software builds on the NSA-developed Ghidra reverse engineering framework that has change into a perennial favorite amongst researchers because it was declassified and made broadly out there within the 2010s. It performs a variety of essential features, together with binary disassembly into assemble language listings, reconstructing management stream graphs and decompiling meeting listings into one thing that a minimum of resembles code.
However, to use Ghidra, one nonetheless wants to have the ability to meticulously analyse the decompiled code by evaluating it with the unique meeting itemizing, including feedback, and assigning descriptive names to variables and features.
Here, G-3PO picks up the baton, operating the decompiled code via a big language mannequin (LLM) to achieve a proof of what the operate does together with recommendations for descriptive variable names.
Tenable mentioned this performance would enable an engineer to “gain a rapid, high-level understanding of the code’s functionality without having to first decipher every line”. They can then zero in on probably the most regarding areas of code for deeper evaluation.
Two of the opposite tools, AI for Pwndbg and AI for GEF, are code debugging assistants that act as plugins for two standard GNU Debugger (GDB) extension frameworks, Pwndbg and GEF. These interactive tools obtain varied information factors – reminiscent of registers, stack values, backtrace, meeting and decompiled code – that may assist a researcher discover the debugging context. All the researcher has to do is ask it questions, reminiscent of “what is happening here?” or “does this function look vulnerable?”
Tenable mentioned these tools would assist remedy the issue of navigating the steep studying curve related to debugging, turning GDB right into a extra conversational interface the place researchers can primarily focus on what is going on with out the necessity to decipher uncooked debugging information. The software is under no circumstances flawless, however it has proven promising leads to decreasing complexity and time, and Tenable hopes it is also used as an academic useful resource.
Other tools being made out there embody BurpGPT, a Burp Suite extension that lets researchers use GPT to analyse HTTP requests and responses, and EscalateGPT, an AI-powered software that probes for misconfigurations in identification and entry administration (IAM) insurance policies for cloud environments, one of the widespread and ignored considerations amongst enterprises, and makes use of GPT to determine potential escalation alternatives and mitigations.
Silver lining
Tenable mentioned that whereas it was to be anticipated that menace actors will reap the benefits of generative AI themselves, and it was most likely solely a matter of time earlier than the specter of dependable, AI-written malware is realised, there’s a silver lining in that there’s nonetheless “ample opportunity” for defenders to harness generative AI, too.
Indeed, in some regards, reminiscent of log parsing, anomaly detection, triage and incident response, they might even get the higher hand.
“While we’re only at the start of our journey in implementing AI into tools for security research, it’s clear the unique capabilities these LLMs provide will continue to have profound impacts for both attackers and defenders,” wrote the analysis group.
