AI Wrote Better Phishing Emails Than Humans in a Recent Test

Posted by in categories: cybercrime/malcode, government, information science, robotics/AI

Natural language processing continues to find its way into unexpected corners. This time, it’s phishing emails. In a small study, researchers found that they could use the deep learning language model GPT-3, along with other AI-as-a-service platforms, to significantly lower the barrier to entry for crafting spearphishing campaigns at a massive scale.

Researchers have long debated whether it would be worth the effort for scammers to train machine learning algorithms that could then generate compelling phishing messages. Mass phishing messages are simple and formulaic, after all, and are already highly effective. Highly targeted and tailored “spearphishing” messages are more labor intensive to compose, though. That’s where NLP may come in surprisingly handy.

At the Black Hat and Defcon security conferences in Las Vegas this week, a team from Singapore’s Government Technology Agency presented a recent experiment in which they sent targeted phishing emails they crafted themselves and others generated by an AI-as-a-service platform to 200 of their colleagues. Both messages contained links that were not actually malicious but simply reported back clickthrough rates to the researchers. They were surprised to find that more people clicked the links in the AI-generated messages than the human-written ones—by a significant margin.

“I am used to being harassed online. But this was different,” she added. “It was as if someone had entered my home, my bedroom, my bathroom. I felt so unsafe and traumatized.”

Oueiss is one of several high-profile female journalists and activists who have allegedly been targeted and harassed by authoritarian regimes in the Middle East through hack-and-leak attacks using the Pegasus spyware, created by Israeli surveillance technology company NSO Group. The spyware transforms a phone into a surveillance device, activating microphones and cameras and exporting files without a user knowing.

Hiding malware inside AI neural networks

Posted by in categories: cybercrime/malcode, robotics/AI

A trio of researchers at Cornell University has found that it is possible to hide malware code inside of AI neural networks. Zhi Wang, Chaoge Liu and Xiang Cui have posted a paper describing their experiments with injecting code into neural networks on the arXiv preprint server.

As grows ever more complex, so do attempts by criminals to break into machines running new technology for their own purposes, such as destroying data or encrypting it and demanding payment from users for its return. In this new study, the team has found a new way to infect certain kinds of computer systems running artificial intelligence applications.

AI systems do their work by processing data in ways similar to the . But such networks, the research trio found, are vulnerable to infiltration by foreign code.
