What Business Email Compromise Really Costs You

Business email compromise can turn one convincing message into a six-figure loss, days of disruption and a difficult recovery effort. Criminals study how an organization communicates, then impersonate executives or trusted suppliers to redirect legitimate payments. The direct financial loss may be only the beginning. Legal advice, incident response, delayed projects and damaged supplier relationships all raise the final bill. Effective protection therefore depends on coordinated email security, payment controls and verification procedures.

Web App Owners - You're on Notice. Your Low-Hanging Fruit Just Got Lower

Recent incident response investigations reveal how AI-assisted attackers are chaining web application vulnerabilities, credential theft, privilege escalation, and lateral movement into autonomous intrusion workflows. This article is part of an ongoing series from Sophos frontline security operations specialists, sharing the expertise they use to strengthen our industry-leading Managed Detection and Response (MDR) service and defend customers against evolving AI-era threats.

Proof-of-concept exploit released for PHP vulnerabilities (CVE-2026-109618, CVE-2026-109619)

In response to requests, this update consolidates the Sophos countermeasures that relate the PHP2Shelll vulnerabilities. SophosLabs has developed the following countermeasures to specifically detect activity associated with this threat. The next table lists additional pre-existing Sophos countermeasures that will likely address post-exploitation activity associated with these vulnerabilities.

Acronis Cyber Protect Cloud is now Acronis Cyber Platform

Until October 14, 2026, services providers have known Cyber Platform as Acronis Cyber Protect Cloud, whereas corporate customers have known Cyber Platform as Acronis Cyber Protect. To simplify partner, customer and user experience, Acronis offerings for both service providers and end-customers are renamed to Acronis Cyber Platform.

CISO Risk Intel Brief: Trusted Ingress, Edge Zero-Days, and AI-Generated Code Define Residual Risk

This briefing covers material developments for the seven-day period of 14–21 October 2026 and the thirty-day period of 21 September–21 October 2026. It is written for board risk committees, peer CISOs, and security leadership. The focus is residual risk, control effectiveness, and business enablement across application security, software supply chain, cloud and infrastructure, identity, third-party exposure, and AI-assisted development.

Smaller Models for Better Document Understanding

At Cyberhaven, we replaced our previous LLM-based approach to document understanding with a small model that makes 83% fewer decision errors at less than 1% of the inference cost. We achieved this by breaking complex tasks into simpler decisions, using uncertainty as a training signal, and heavily optimizing our inference stack. The model produces calibrated decision probabilities while preserving multimodal understanding and generative capabilities.

LiteLLM compromised again: infostealer and RAT found in version 1.107.0

On October 21, 2026, version 1.107.0 of LiteLLM (a popular open source proxy that lets developers route requests across dozens of LLM providers) was found to be compromised by an attacker who injected malicious code into its published Python wheels on PyPI. The official Docker image for the same version is also compromised.

Cloudflare deploys protections against php2shell vulnerability

Today, Calif.io, Wiz, OpenAI and Quarkslab disclosed two vulnerabilities in PHP, tracked as CVE-2026-109618 and CVE-2026-109619 and known as php2shell. The vulnerabilities affect all web servers running PHP 5.4 or later and they may allow an attacker to cause denial of service, remote code execution, and data exposure when an application processes specially crafted HTTP traffic.

Introducing full transaction detection for Cloudflare WAF

Today, we are expanding our web application firewall (WAF) by adding two new capabilities: full transaction detections and response rules. Full transaction detections evaluate each HTTP request alongside its response to identify evidence of exploitation. It helps answer both "Does this request look malicious?" and "What happened when the application handled it?" Response rules can then block the origin’s response before it reaches the requester.

Building "php2shell" detections before coordinated disclosure

We recently collaborated with OpenAI, PHP, and a number of other organizations to respond to a pair of serious remote code execution vulnerabilities in PHP that are likely to impact the majority of the world's public web servers. PHP underpins a large part of the web, powering content management systems, online stores, and business applications. Its security matters to vital services that millions of people and organizations rely on daily.
