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 was not subtle. Executives, partners, and customers all kept coming 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 analysts at BTIG, who spoke with vendors and customers throughout the conference. AI agents can scout systems, probe for weaknesses, and launch attacks with a speed and scale that human-run operations simply cannot match. As CNBC Tech reported, conference attendees arrived in Las Vegas specifically hunting for ways to stop rogue AI agents from breaching their systems.

For ordinary businesses, that means the old playbook is already out of date. A firewall and a password policy are not enough when your attacker is software that works around the clock and learns as it goes.

Why did stocks jump so sharply?

Investors read the conference mood as a signal that spending on security tools is about to accelerate. CrowdStrike and Palo Alto Networks, two of the biggest names in enterprise cybersecurity, 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. The firm pointed to Palo Alto's identity platform as a natural fit for a world full of AI agents, each of which needs its own credentials and permissions. 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.

Rubrik, Tenable, Netskope, and Zscaler each gained between 5% and more than 7% on the day.

What does this mean for everyday businesses?

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

For a small business owner or IT manager, the practical message is straightforward. The tools your team relied on two years ago were built for a slower threat. Ask your current security provider what they are 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 the threat and the defence is real right now. Closing that gap is what the next wave of cybersecurity spending is aimed at.

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 are not 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.
