On July 22, 2026, two big stories crossed paths: a surge of threats to the physical and digital systems that keep society running, and a round of company earnings reports that told very different stories about the AI boom.

What's Threatening Our Infrastructure?

A think tank called the Center for Strategic and International Studies (CSIS) held a webcast on July 22 about how NATO can protect critical undersea infrastructure — things like the cables that carry internet data across oceans (CSIS).

This didn't come out of nowhere. Reuters reported on April 7 that Iranian hackers had stepped up attacks on US critical infrastructure since the start of 2026, targeting government services, facilities, and water and wastewater systems (Reuters). On March 3, Reuters reported that US banks were on high alert for cyberattacks amid the US war in Iran (Reuters). Sweden told its energy companies to raise security after a cyberattack hit Polish infrastructure, Reuters reported on February 26 (Reuters).

On the political side, Deutsche Welle reported on July 22 that US senators criticized Defense Secretary Pete Hegseth over his Iran war strategy (Deutsche Welle). The Economic Times ran a live blog that day in which Iran stated it was "prepared for all scenarios" (Economic Times).

The Government's Cyber Agency Responds

CISA — the Cybersecurity and Infrastructure Security Agency — is the federal agency in charge of protecting the systems that keep the country running, like power grids and water supplies. It was busy in July.

On July 1, CISA announced a new Advisory Council to strengthen partnerships and secure critical infrastructure. On July 13, the agency released a warning called "Improve Router Hygiene to Protect Against Russian State-Sponsored Targeting" — telling organizations to clean up their router settings because Russian hackers were exploiting weak ones (CISA). The next day, CISA joined NSA, FBI, DC3, and international partners to warn that Russian hackers are targeting vulnerable networking devices in critical infrastructure worldwide (CISA).

On July 14, CISA urged organizations to tighten security on SharePoint, a widely used collaboration software, after new attacks were discovered. On July 16, CISA added a specific software flaw — labeled CVE-2026-58644 — to a list of known vulnerabilities that hackers are actively exploiting (CISA). CISA also added two other exploited vulnerabilities to that list on July 7.

Two Companies, Two Different Stories

While all of this was happening, two major companies reported their earnings — how much money they made — and the market reacted very differently to each.

GE Vernova, which makes power equipment, reported its second quarter results on July 22 and raised its expectations for the full year, saying strong demand for electricity was boosting orders (GE Vernova; Reuters). A lot of that demand came from companies building AI data centers, which need massive amounts of power. But GE Vernova missed its profit targets, and its wind turbine business kept struggling. Despite the good news about AI orders, the stock fell (Yahoo Finance).

Super Micro Computer, which makes servers for AI data centers, went the other way. Its stock jumped about 20% on July 22 after the company reported better-than-expected profit margins and said those margins would nearly double (Barron's; WSJ; QZ).

Why This Matters

The broader picture is a market juggling two stories at once. AI is driving real growth — more electricity demand, more server orders, better profits for some companies. But the infrastructure making all of that possible, from undersea cables to power grids to the software running financial systems, is under active threat from countries like Iran and Russia. Those threats aren't abstract. They hit the same systems that data centers, energy networks, and banks depend on.

The GE Vernova result is a useful lesson. Even with surging AI orders and a higher forecast for the year, the company missed its profit target because its older wind business struggled. The stock dropped. In other words, growing sales doesn't automatically mean growing profits if part of your business is dragging you down.

For banks and other financial firms, the CISA warnings carry real weight. These aren't generic safety tips. They describe specific ways hackers are already breaking in. Financial institutions have been on high alert since March, and now they face documented threats from both Iranian and Russian hackers.

The geopolitical tension around Iran — including senators criticizing the defense secretary and Iran saying it's ready for "all scenarios" — adds another layer of uncertainty. Markets are still processing what that means. On July 22, that tension flowed into stock trading alongside oil prices and defense stocks, all in the same session that saw Super Micro surge and GE Vernova slide.
