June 17 (Reuters) - Cyber ‌warfare startup ​Twenty ​said on Wednesday it has raised $100 million in a funding round that valued it ‌at $1 billion, underscoring growing investor interest in ⁠cybersecurity and defense technology.

The round, led by Accel, brings the ‌company's total fundraising to $138 ‌million since its founding in 2024.

Other investors such as Point72 Ventures, Friends & Family Capital, Caffeinated Capital ​also participated in the latest funding.

The fresh capital will be used to expand research and ⁠engineering efforts, said Joe Lin, CEO of the Arlington, Virginia-based company, which ​develops AI-enabled cyber capabilities for the U.S. military and intelligence community.

Investor interest in cybersecurity ​has increased sharply as mounting ‌concerns over AI-powered cyberattacks prompt governments and organizations to boost spending on digital ⁠security and defense.

"America is under sustained cyberattack, and our adversaries have learned — correctly — that those attacks rarely ⁠carry consequences," Lin said.

Reuters had reported in April that U.S. cybersecurity ​and intelligence agencies warned of escalating Iranian cyberattacks targeting critical infrastructure sectors.

In March, Iran-linked hackers breached FBI Director Kash ‌Patel's personal email account, publishing photographs and other documents online in a high-profile ‌cyberattack.

Israeli researchers have also linked Iranian hackers to ⁠a separate cyberattack in ‌March that disrupted ​parts of Los Angeles' transit system.
