April's cybersecurity surge is accelerating across sectors that were already underprepared. Jones Day, one of the largest U.S. law firms, confirmed that hackers accessed client files after stolen materials appeared online. [1] The breach was attributed to the Silent ransomware group, which the FBI flagged in a 2025 alert as specifically targeting American law firms. [2]

The legal sector is not alone. Cyberattacks on schools, healthcare systems, and municipal infrastructure have intensified through March and April, with the FindLaw report documenting phishing as the primary entry vector. [3] The pattern is opportunistic: organizations distracted by the war's economic disruptions — budget cuts, staffing shortages, supply chain diversions — are softer targets.

Behind it all sits the FBI wiretap breach. The bureau classified the hack of its Digital Collection System — the network used to manage court-authorized surveillance — as a FISMA "major incident" last week, the most serious classification available. [4] The breach, first discovered in March, may have been a supply chain attack, with investigators exploring whether a nation-state was involved. [5]

The convergence is the story: a federal surveillance system compromised, major law firms breached, schools and hospitals hit — all in the same quarter. Cybersecurity was underfunded before the war. The war made it worse. And the attackers noticed.
