Hans Vestberg and Jeff Greene are connected through the Salt Typhoon telecommunications cyberespionage crisis, not through a known business partnership or personal relationship. Vestberg was Verizon’s chief executive when the company was dealing with the intrusion, while Greene was a senior cybersecurity official at the U.S. Cybersecurity and Infrastructure Security Agency, or CISA.
A December 2024 Reuters report named both men in its coverage of the federal response. Reuters reported that Vestberg attended a November 22 White House meeting with telecommunications executives, while Greene later said officials could not yet predict when compromised networks would achieve a “full eviction” of the attackers. There is no public confirmation that Vestberg and Greene were business partners, coworkers or direct collaborators.
Which Jeff Greene is connected to Hans Vestberg?
The Jeff Greene in this story is the cybersecurity and national-security professional who served as CISA’s Executive Assistant Director for Cybersecurity in 2024.
He should not be confused with Jeff Greene, the billionaire real-estate investor, or Jeff Green, without the final “e”, who is the cofounder and CEO of The Trade Desk. The distinction matters because some online profiles about Hans Vestberg and Jeff Greene have incorrectly substituted the real-estate investor.
Cybersecurity official Jeff Greene has worked across government, technology policy and private-sector security. He earned a B.A. in International Relations from Boston University and a J.D. with honor from the University of Maryland, according to a George Washington University biography.
How Salt Typhoon connected their names
Salt Typhoon was the name widely used for a cyberespionage campaign that penetrated major telecommunications networks. U.S. agencies attributed the activity to actors affiliated with the People’s Republic of China, while Chinese officials rejected U.S. hacking allegations.
The White House readout from November 22, 2024 said senior officials met telecommunications executives to discuss a significant cyberespionage campaign against the sector and steps to strengthen network security. The official readout did not publish a participant list, but Reuters reported that Vestberg was among the executives who attended.
The federal response continued into December. CISA and partner agencies issued hardening guidance for communications infrastructure, focusing on visibility, configuration management and stronger network defenses.
The FBI later said the broader campaign involved theft of call-data logs, access to a limited number of private communications and information connected with some court-ordered law-enforcement requests.
Hans Vestberg’s role at Verizon
Vestberg was running Verizon when Salt Typhoon became a major national-security issue. Reuters reported that he joined other telecom leaders at the November 2024 White House meeting as government officials and network operators worked to understand and contain the intrusion.
Verizon said on January 10, 2025 that it had contained the incident affecting its own network. Its Salt Typhoon update said the company had worked with federal law-enforcement and national-security agencies as well as outside cybersecurity specialists.
That statement applied to Verizon’s own incident, not to every affected telecommunications network. In June 2025, the U.S. Senate Commerce Committee sought additional information from Verizon and AT&T about remaining vulnerabilities and the basis for their containment claims.
Jeff Greene’s role at CISA
CISA formally appointed Greene as Executive Assistant Director for Cybersecurity in July 2024. In that position, he led the agency division responsible for major federal cybersecurity programs and work with critical-infrastructure organizations.
His role put him on the government side of the Salt Typhoon response. In December 2024, Greene told reporters that it was impossible at that stage to predict when there would be complete “full eviction” of the attackers from affected networks, reflecting the difficulty of proving that a sophisticated intruder has been removed from every possible foothold.
That challenge is central to large-scale telecom security. Removing one malicious account or fixing one compromised device does not necessarily prove an attacker has lost every access path across a complex network.
Did Hans Vestberg and Jeff Greene work together?
There is no public confirmation that Vestberg and Greene worked together directly.
Their connection is institutional. Vestberg led Verizon, one of the telecom companies responding to Salt Typhoon. Greene held a senior role at CISA, the federal agency helping coordinate cybersecurity guidance and response across critical infrastructure.
Reuters placed both names in the same Salt Typhoon story, but that does not establish that they met, communicated directly or worked on a joint project. Greene’s attendance at the November 22 White House meeting has also not been publicly established.
Hans Vestberg’s career before and after Verizon
Vestberg built his career in telecommunications long before joining Verizon. He studied business administration at Uppsala University and spent nearly three decades at Ericsson, eventually becoming its president and CEO in 2010.
Ericsson’s historical material records an unusual early interest alongside his business career: Vestberg grew up in Hudiksvall, Sweden, and hoped to become a professional handball player. He competed at Sweden’s top level and continued playing during international assignments in Brazil and Chile.
His rise at Ericsson included senior finance and operating roles before he became chief executive. The company later recounted that, while serving as CFO in 2009, he received a call from chairman Michael Treschow asking him to take the top job.
After leaving Ericsson in 2016, Vestberg joined Verizon in April 2017 as executive vice president, president of Global Networks and chief technology officer. He became CEO on August 1, 2018 and chairman in March 2019.
His Verizon years were closely tied to heavy investment in wireless infrastructure, particularly 5G and spectrum. In a June 2025 Fast Company interview, Vestberg defended Verizon’s roughly $52 billion 2021 spectrum purchase as a long-term infrastructure decision, summing up the requirement simply: “you need spectrum.”
Verizon replaced Vestberg as CEO and chairman in October 2025 with Dan Schulman. The company’s CEO transition announcement said Vestberg would remain a special adviser through October 4, 2026.
His post-Verizon work has continued across technology, finance and infrastructure. Evercore announced on October 5, 2026 that Vestberg had joined the firm as a senior adviser. He is also listed by Consello as a Senior Operating Advisor and by BlackRock as a director. Corporate filings in 2026 also documented advisory roles involving Digi Power X and US Data Centers.
Jeff Greene’s path through cybersecurity
Greene’s route into cybersecurity began in public policy rather than in a technical operations role. In a 2020 NIST interview, he said his move into cybersecurity happened almost accidentally while he was working for the Senate Homeland Security Committee in 2009. An assignment that began as a small part of his work soon became his full-time focus.
He later worked at Symantec, served as director of the National Cybersecurity Center of Excellence at the National Institute of Standards and Technology, and held the role of Chief for Cyber Response and Policy on the White House National Security Council in 2021 and 2022.
Greene has repeatedly worked at the boundary between government and industry. In the NIST interview, he described the appeal of the National Cybersecurity Center of Excellence in terms of solving practical problems by bringing public- and private-sector participants together. That approach is especially relevant to telecommunications security, where most critical infrastructure is operated by companies but government agencies hold intelligence, investigative and coordinating responsibilities.
By February 2025, Greene was no longer leading CISA’s cybersecurity division; Karen Evans had taken over the post.
As of September 30, 2026, a Travelers Institute biography identified Greene as Founder and Partner of Civira Partners and a Senior Associate at the Center for Strategic and International Studies. His CSIS profile describes him as a cofounder of Civira Partners and a nonresident senior associate in its Strategic Technologies Program. Cambridge Global Advisors also lists him as a senior adviser.
Why the connection still matters
The Hans Vestberg and Jeff Greene connection is useful because it shows how a major cyber incident can bring corporate infrastructure leaders and federal cybersecurity officials into the same public story without making them business partners.
Vestberg’s responsibility was tied to operating and securing one of the country’s largest communications networks. Greene’s was tied to the federal effort to understand the threat, coordinate with infrastructure operators and improve defenses across the sector.
Both have since moved on from the positions they held during Salt Typhoon. Vestberg is no longer Verizon’s CEO, and Greene is no longer CISA’s Executive Assistant Director for Cybersecurity. Their names remain linked because of the same 2024 crisis, not because of a separate personal or commercial relationship.
