AI tools are drastically improving the speed of the reconnaissance stage of targeted social engineering attacks, according to researchers at ESET. Attackers can use these tools to trawl the internet for publicly available information about potential victims, and incorporate this information into personalized spear phishing attacks.

Researchers at Gen Digital are tracking a sophisticated social engineering campaign that’s using phony NDA documents to trick employees into moving the conversation to WhatsApp and personal email accounts. The attackers targeted an employee at Gen itself, but the employee recognized that it was a scam and played along to see what the attackers would do. The threat actors first impersonated a real Gen executive based in Dublin, who introduced a second impersonated person who claimed to work at PwC.

Social engineering has always been the softest edge of enterprise defense, and AI is sharpening adversaries’ attacks. Phishing, business email compromise, and impersonation still dominate the initial-access playbook, but AI has stripped out the cost, time, and skill barriers that once forced attackers to choose between reach and precision.

AI is making social engineering attacks significantly more effective, according to a new report from cyber insurance firm Resilience. These attacks were behind more than 85% of losses in the first half of 2026, compared to less than 20% during H1 2024. “Losses tied to phishing, social engineering, and transfer fraud have climbed from 17.7% of incurred losses in H1 2024 to 85.3% in H1 2026, the single largest increase in the report’s five half-year comparison,” Resilience says.

BlueVoyant researchers identified a new deployment method for the FireClient backdoor during investigations into Microsoft Teams-based social engineering campaigns.

This year National Social Engineering Day falls on Aug. 6. This day is designed to give us an opportunity to remind people that cybercriminals do not always need sophisticated malware, an undisclosed vulnerability or a dark room filled with glowing monitors, sometimes, all they need is a good story. Social engineering existed long before computers. Confidence tricks, impersonation, false authority and appeals to greed or fear have been used for centuries.

Threat actors continue to rely on social engineering as AI is incorporated into their attacks, according to ESET’s Threat Report for the first half of 2026. ESET’s Director of Threat Prevention Labs, Jiří Kropáč, stated, “Rather than relying on entirely new methods and tools, attackers are quickly adapting established techniques to new platforms, technologies, and user behaviors.

The ClickFix social engineering technique is now the top malware delivery method, according to a new report from ReliaQuest. These attacks trick users into copying a malicious command, then pasting it into a terminal and running it on their computers. “ClickFix remained the dominant delivery method this period and, for the first time, we observed it expand to macOS, delivering infostealers onto a platform many organizations still monitor less closely than Windows,” the researchers write.

There’s an important metric that can tell you exactly how vulnerable your high-risk employees and departments are to the next generation of social engineering. It’s not phishing click rates or training completion percentages. It probably doesn’t show up on any security dashboard. It’s the precise number of days it takes your team to respond to a live, context-specific threat with adequate training – training time to market.
