ASOS later confirmed to Sky News that an unauthorized customer notification had been sent and said it was investigating activity involving third-party platforms used to communicate with customers. The company also said basic personal information, including names and contact details, may have been accessed, while payment-card informatio

Securing Agent-to-Agent Communication: The Next Identity Frontier

As organizations deploy autonomous AI agents, security teams face a significant shift as non-human non-human entities making decisions, invoking tools, and delegating tasks to other agents without human intervention. Security architectures built around human users, static APIs, and distinct endpoints break down when AI agents dynamically collaborate across an environment. As these interactions become more common, securing agent-to-agent communication without blocking adoption will require security leaders to treat autonomous agents as first-class identities, with their own permissions, behavio

SMTP is the key: BPFDoor and AVERAT hitting the network edge

OverviewRapid7 tracked a set of Linux samples that blend into the software and device conventions of the telecom environments they target. The set spans a newly observed BPFDoor variant, a BPF Rekoobe build seen against South Korean targets, a dropper, and six builds of a Linux implant we track as AVERAT, deployed against Taiwanese appliances. Additionally, we provide source code details of the Rapid7 BPFDoor controller introduced in our April 2026 blog, Stealthy BPFDoor Variants are a Needle That Looks Like Hay.The chain uses two binaries.

How AI Is Changing the Roles Required in the Security Operations Center

As AI takes on more of the enrichment, correlation, and initial assessment inside the SOC, roles, skills, and KPIs still require deliberate redesign. Security leaders need to decide where automation is dependable, where human judgment should remain decisive, and how teams should be measured when alert handling is no longer the center of the operating modelThe Gartner® report, The Roles Required for the AI-Enabled Security Operations Center (SOC), examines the roles and capabilities Gartner expects the SOC to require as AI becomes embedded in security operations. Rapid7 is offering complimentar

When Business Email Compromise Starts Rewriting Reality

Business Email Compromise (BEC) operates on a familiar playbook. Threat actors breach a mailbox, silently monitor operations, map approval chains, and ultimately exploit that access to divert funds or exfiltrate sensitive assets.This dynamic is central to our analysis as we kick off a series around Rapid7's collaborative research with Zimbra; upcoming installments will explore technical details and broader findings based within the Zimbra Collaboration Suite. Our investigation disrupted the traditional BEC model in unexpected ways. We uncovered over 50 vulnerabilities, and found that several a
