FTC Reaches Settlement in Publicis’s $2.2 Billion LiveRamp Acquisition
On October 19, 2026, the Federal Trade Commission (FTC) announced that it had entered a proposed consent order resolving its concerns over Publicis’s $2.2 billion acquisition of LiveRamp. The case is notable for relying on a purely vertical theory of harm centered on Publicis’s control over previously neutral data pipelines. The remedies ordered by the FTC are designed to ensure that neutrality continues after the acquisition. Firms should expect that deals involving important data infrastructure layers, most significantly artificial intelligence (AI) and related technologies, will face similar scrutiny.

Cybersecurity Vulnerabilities and Security Updates: Why Hours Matter, What Defense Tech and Dual Use Companies Should Do Now
On October 21, 2026, the PHP project patched two critical remote-code-execution vulnerabilities, together called php2shell, that affect nearly every system running PHP to serve web traffic, including sites built on WordPress, Drupal, and Magento, as well as many custom portals. Technical details of the vulnerability leaked before the fix was released, so the window between disclosure and active exploitation was short. Patching is available and inexpensive. The cost of waiting for exposed companies is not only a possible breach, but also the legal and contractual exposure that the delay itself creates—especially for heavily regulated entities, such as U.S. government contractors that handle Controlled Unclassified Information (CUI).
