The US federal judiciary has confirmed that it has been targeted by a series of escalated cyberattacks, resulting in a significant breach of its electronic case management and filing systems. Recent investigations revealed that hackers accessed sensitive data, including the identities of informants and confidential case files, raising concerns about the safety of witnesses. In response, the judiciary is enhancing its security measures to protect against future threats. The federal court filing system, known as PACER, has been particularly affected, prompting calls for immediate upgrades to prevent further intrusions. This incident marks a significant escalation in cyber threats against the US judicial system, reminiscent of past high-profile hacks such as the 2020 SolarWinds breach.
