Most attacks do not start with malware. They mostly start with access. Attackers find new ways to steal credentials, which they then use to gain unauthorized access. They also use legitimate tools to gain access to systems without triggering alerts. To repeat their actions across environments, they make use of automation. Modern attacks, such as phishing, ransomware, zero-day exploits, and insider threats, target both systems and users.

Sophos X-Ops looks at the Atomic macOS Stealer and its capabilities Sophos Managed Detection and Response (MDR) teams recently responded to a customer incident involving an infostealer infection on a macOS host. When we investigated, we found that the infostealer appeared to be a variant of AMOS (Atomic macOS), a well-known malware family we’ve written about before. The attack began with a ClickFix-style ruse, where a user was tricked into running a terminal command.

Defenders have long known that richer evidence improves security outcomes by enabling faster triage, deeper analysis, and more complete investigation. Although Corelight was founded on this premise, it’s been hard for us to quantify the impact of better network data - until now. Recently, we built an agentic test harness to measure the success of frontier LLMs in responding to real-world attack scenarios, using a range of source data.

Seven things security teams can start doing today to reduce risk.

Sophos Endpoint in action: Blocking a novel supply chain attack How the unique anti-exploitation capabilities included with Sophos Endpoint blocked a supply chain attack. Sophos Endpoint is architected from the ground up to automatically block exploits, ransomware, and attacker techniques by default with zero manual tuning.
