And they're being stressed by geopolitical concerns that threaten to slow important data-sharing efforts

Researchers from Georgia Tech have found that the supply chain for threat intelligence data is susceptible to adversarial action, and proposed a method to improve data sharing that they think will make it stronger.

Brenden Kuerbis, a research scientist at the Georgia Tech's School of Public Policy sketched the proposal on Monday by noting that in January 2026, China appeared to ban security software developed by some US and Israeli firms – probably because it fears data leakage if local firms use the foreign software.

“This move represents more than just another salvo in ongoing tech tensions between the two governments,” he wrote. “It threatens to fracture a foundational practice of internet cybersecurity: the global threat intelligence ecosystem that allows defenders worldwide to collect, analyze, and share information about emerging attacks and responses to cyber threats that know no borders.”

According to other researchers at the institution, the ecosystem was ...
