Hans Vestberg and Jeff Greene are linked by Salt Typhoon, a hacking campaign aimed at phone companies. Vestberg led Verizon when it happened. Greene was a senior cybersecurity official at a U.S. government agency called CISA. Public sources show they were part of the same news event. They do not show a business deal or a close personal tie.
This guide explains who each man is, what happened, and what the records do and do not prove.
Hans Vestberg and Jeff Greene: What Is the Documented Connection?
The link comes from Reuters. In a December 4, 2024 report, Reuters said Vestberg attended a White House meeting on November 22, 2024. The meeting was about the phone network break-ins.
The same report quoted Greene, who was then a CISA official. He said officials could not predict when the hackers would be fully removed from the hacked networks.
So the two men appear in the same story. They had different jobs in it. One ran a phone company. The other worked for a government agency that helps defend networks.
Who Is Jeff Greene in the Salt Typhoon Story?
Two different people share the name Jeff Greene. This causes real confusion online.
The Jeff Greene in this story is a cybersecurity expert. The Center for Strategic and International Studies (CSIS) describes him as a former executive assistant director for cybersecurity at CISA. His earlier jobs include work at the National Security Council, the National Institute of Standards and Technology (NIST), and Symantec. He also worked for congressional homeland-security committees.
The other Jeff Greene is a real-estate investor. Forbes has a separate profile of him. He is not the person named in the Salt Typhoon reporting.
What Was Salt Typhoon?
Salt Typhoon was a campaign by hackers linked to China. The FBI and CISA shared a joint statement about it on November 13, 2024. They said the hackers got into several phone company networks.
The agencies also said their understanding of the break-ins could grow as the investigation went on. So early reports may not show the full picture.
Here is what the agencies said was taken or reached:
- Call records, which show who called whom and when
- Private communications of a limited number of people
- Information tied to certain court-ordered law-enforcement requests
Call records are not the same as the words spoken on a call. The agencies named these as separate items. Readers should keep them apart.
On December 4, 2024, CISA and partner agencies also shared guidance for people who run phone networks. It explains how to see more of what happens on a network and how to harden it.
Hans Vestberg’s Role at Verizon
Verizon says Vestberg was its CEO from 2018 to 2025. Before that, he was president and CEO of Ericsson from 2010 to 2016.
On January 10, 2025, Verizon said it had contained the incident that hit its own network. It said it worked with federal agencies and cybersecurity experts.
Verizon’s statement drew a line between a small group of targeted people and other customers. It said call records and mobile-internet information were accessed for the other customers. This is not the same as saying every customer’s calls were heard.
That statement covers Verizon only. It does not say every affected phone company was secured.
A Short Timeline

| November 22, 2024 | Reuters says Vestberg attended a White House meeting on the break-ins. |
| December 4, 2024 | Reuters reported on a Senate briefing and quoted Greene. CISA shared network guidance the same day. |
| January 10, 2025 | Verizon said it had contained the incident on its own network. |

| October 5, 2026 | Evercore announced that Vestberg joined the firm as a senior adviser. |
Jeff Greene’s Role in the CISA Response
Greene was a senior CISA cybersecurity official during the incident. The Reuters report shows him speaking in public about how hard it was to say when the hackers would be fully out.
The sources reviewed do not say he ran Verizon’s own response. They also do not say he led the response together with Vestberg. Greene spoke for the government side. Vestberg led a company that was hit.
Did Hans Vestberg and Jeff Greene Work Together Directly?
The public record does not show it. Reuters documents their separate roles in the same event. The official sources we reviewed do not show a joint project, a business partnership, or a close personal tie.
This is not proof that they never spoke. It only means the public record does not show it. A shared news story is not the same as a working relationship.
Be careful with claims that say more than that. Neither man should be blamed for the break-ins based on these sources.
