Swiss Government Confirms Radix Ransomware Attack Leaked Federal Data

The Swiss government has confirmed that sensitive federal data has been leaked onto the dark web following a ransomware attack on Radix, a non-profit health promotion foundation serving multiple federal offices.

The breach, attributed to the Sarcoma ransomware group, has raised fresh concerns about the security of government contractors and the ripple effects of cyberattacks on public sector data.

Radix, based in Zurich, disclosed it was attacked on June 16, with hackers both stealing and encrypting data.

When ransom demands were not met, the Sarcoma group published approximately 1.3 terabytes of documents—including financial records, contracts, and private correspondence—on its leak portal on June 29.

The Swiss government confirmed on June 30 that the breach resulted in federal data being exposed, though it emphasized that the attackers did not gain direct access to core government IT systems, as Radix operates independently and holds no direct system links.
