Mikko Hyppönen Applies Cybersecurity Methods To Counter Drone Threats

Mikko Hyppönen, Chief Research Officer at Sensofusion, said cybersecurity principles used to detect malware are now being applied to counter drone threats. He presented the concept during a cybersecurity conference, comparing threat detection to pattern recognition systems used in both software and radio signals.

From Early Viruses To A Beacon In Malware Defense

Hyppönen began his career in the late 1980s, when computer threats were primarily spread through floppy disks and categorized as viruses or trojans. Early work included analyzing malware samples and reverse engineering software protections. During his time at F-Secure, formerly Data Fellows, he examined thousands of malware variants as threats evolved. Incidents such as the ILOVEYOU virus, which infected more than 10 million systems, marked a shift toward large-scale attacks.

Modern Cybersecurity And The New Era Of Drone Warfare

The cybersecurity sector has grown into a global industry valued at approximately $250 billion, with increasing investment in system protection and threat detection. At the same time, new risks have emerged through the use of drones in military and civilian contexts. Hyppönen now focuses on counter-drone technologies at Sensofusion, applying cybersecurity methods to detect and disrupt unmanned aerial systems. Use of drones in conflicts, including the war in Ukraine, has accelerated development in this area.

Counters And Cyberattacks: The Convergence Of Old And New Threats

Detection systems for drones rely on identifying radio frequency patterns, similar to how malware is identified through digital signatures. Analysts use recorded signal data to classify and respond to potential threats. Hyppönen said cyber threats have shifted toward criminal and state-linked activity, requiring continuous adaptation of defense systems. He added that similar approaches are now used to address risks from autonomous aerial technologies.

OpenAI Brings Unlimited Text Chats To Free ChatGPT Users

Unlimited Text Conversations Roll Out

OpenAI is removing limits on text-based conversations for all ChatGPT users, following the platform’s recent milestone of surpassing one billion weekly users.

The update introduces GPT-5.6 Luna as the default model for Free and Go users, replacing GPT-5.5.

New “Think” Button For More Complex Questions

Alongside unlimited text chats, Free and Go users will gain access to a new “Think” button, allowing them to use additional reasoning power for more complex queries.

OpenAI noted that separate usage limits will continue to apply to file uploads, image generation, voice features and other multimodal tools.

Faster Responses For Paid Subscribers

The update also brings improvements for ChatGPT Plus and Pro subscribers. They will receive access to GPT-5.6 Sol, an upgraded model designed for everyday tasks such as web research, planning, writing, decision-making and answering questions. According to OpenAI, the model delivers shorter, more robust responses.

The company noted that this version is separate from the GPT-5.6 Sol model used in Codex and Work, which remains unchanged. Plus and Pro subscribers will also receive a new thinking slider, allowing them to adjust how much reasoning the model applies before generating an answer, depending on the complexity of the task.

OpenAI Reports Fewer Errors

According to OpenAI’s internal testing, GPT-5.6 Luna produces 62% fewer factual errors than GPT-5.5 Instant, while GPT-5.6 Sol reduces factual errors by 68%.

The updated GPT-5.6 Sol model is available to Plus and Pro users starting today. The remaining features for Free and Go users will roll out throughout the week, with unlimited text chats and the new Think button becoming available next week.
