AI Agents Are the New Hackers, and Cybersecurity Stocks Are Surging Because of It

Key points

• CrowdStrike and Palo Alto Networks each rose more than 5% on Monday, hitting record share prices after the Black Hat cybersecurity conference in Las Vegas.
• Analysts at BTIG said AI agents, software that can carry out multi-step tasks on its own, are now the dominant attack threat facing businesses.
• BTIG raised its price target on CrowdStrike to $237 per share and on Palo Alto Networks to $380 per share.
• Rubrik, Tenable, Netskope and Zscaler also posted gains of 5% to more than 7% on the same day.
• Analysts at Cantor wrote that AI has moved from being a cybersecurity feature to a core part of both attack and defence infrastructure.

Black Hat, the security industry's biggest annual gathering, wrapped up in Las Vegas last week. The headline takeaway wasn't subtle. Every conversation at the conference kept circling back to the same worry: AI agents have changed what attackers can do, and defenders are still catching up.

What did Black Hat actually reveal?

The threat environment is "meaningfully worse", according to BTIG analysts who spoke with vendors and customers throughout the conference. AI agents can scout systems and launch attacks at a speed and scale that human-run operations can't match. Conference attendees arrived specifically hunting for ways to stop rogue AI agents from breaching their systems, CNBC Tech reported.

For ordinary businesses, the old playbook's already out of date. A firewall and a password policy aren't enough when your attacker is software that works around the clock and learns as it goes. Our story from 11 August, "AI agents hacked their way out of labs. Now the security industry is scrambling for answers.", traced exactly how that shift began, starting with the breach of AI platform Hugging Face.

Why did stocks jump so sharply?

Investors read the conference mood as a signal that security spending is about to accelerate. CrowdStrike and Palo Alto Networks each climbed more than 5% on Monday and closed at record highs.

BTIG raised its price target on Palo Alto Networks to $380 a share, roughly 4% above Friday's close, pointing to Palo Alto's identity platform as a natural fit for a world full of AI agents. Each agent needs its own credentials and permissions, and that's a lot of new surface to protect. BTIG also lifted its CrowdStrike target to $237 per share, about 11% upside, citing what it called a "new modernisation cycle" in endpoint security, the software that protects individual devices like laptops and phones. BTIG also raised its Rubrik target to $109 per share.

Tenable and Rubrik each gained more than 7%. Netskope and Zscaler jumped about 5%.

What does this mean for everyday businesses?

Security spending is moving up the priority list fast. Cantor's analysts put it plainly: AI is no longer a feature bolted onto security products. It's now central to how attacks are built and how defences must work.

For a small business owner or IT manager, the practical message is this: the tools your team relied on two years ago were built for a slower threat. Ask your current provider what they're doing specifically about AI-driven attacks, and whether their tools can flag unusual automated behaviour, not just the human kind.

Deployment of proper AI security tools is still early, BTIG notes, which means the gap between threat and defence is real right now.

Common questions

Do I need to worry about AI agents attacking my small business?

AI-powered attacks are most often aimed at larger targets, but the tools that power them are getting cheaper and more accessible, so smaller businesses aren't immune. Keeping software updated and training staff to spot phishing emails remain the most practical first steps.

What is an AI agent, exactly?

An AI agent is software that can plan and carry out a series of tasks on its own, without a human clicking through each step. In a security context, attackers can use agents to probe thousands of systems automatically, looking for gaps to exploit.
