Being alert to ransomware is nothing new. Ransomware can wreak havoc and often cause permanent damage to endpoints, unless effective recovery processes are in place. Many ransomware operators attempt to delete shadow copies and other recovery methods, which makes redundancy in recovery essential. However, the situation becomes even more serious with the emergence of microcode ransomware.

That was the message from major UK retailers like Marks & Spencer and the Co-op during recent Parliamentary hearings on cyber resilience. Their stories weren’t hypothetical, they were recovering from real-world incidents involving identity compromise, supply chain breaches, and operational disruption that cost hundreds of millions of pounds. The lesson is clear. Prevention is necessary, but it is no longer enough.

Aligning with the Australian Government’s Information Security Manual (ISM) and the Essential Eight (E8) remains a foundational step for organizations working with or alongside government agencies. Trustwave’s Essential Eight Control Effectiveness Assessment is a great first step, but relying solely on compliance as a goal can leave security programs stagnant.

A newly discovered exploit, “ToolShell,” is fueling a wave of targeted attacks against on-premises Microsoft SharePoint servers. The zero-day exploit chains two vulnerabilities—CVE-2025-53770, a remote code execution (RCE) vulnerability and CVE-2025-53771, a spoofing vulnerability that allows attackers to bypass authentication. When combined, this critical zero-day vulnerability gives attackers persistent unauthenticated remote access to on-premises SharePoint servers.

JounQin’s npm account, the maintainer of popular packages such as eslint-config-prettier, was compromised in a phishing attack. The attackers used the breached credentials to publish six malicious versions of eslint-config-prettier, along with three additional infected packages tied to the same account. In total, the compromised packages see roughly 78 million weekly downloads. Notably, the account had publishing rights for packages with a combined weekly download count of 180 million!

It’s also its greatest defense The biggest threat in our rapidly evolving cybersecurity landscape is artificial intelligence (AI).1 It’s also our greatest defense. Cybersecurity is a high-stakes game where everything is on the line and decisions have to be made fast. For years, cybersecurity strategy has been about increasing visibility to make informed decisions from vast amounts of data.

Two critical zero-day vulnerabilities in the Microsoft SharePoint Server environment, CVE-2025-53770 (9.8 CVSS score) and CVE-2025-53771 (6.5 CVSS score), are being actively exploited by threat actors to compromise vulnerable on-premises SharePoint servers. The two new vulnerabilities are part of a complex attack chain dubbed “ToolShell”, which grants threat actors access to unpatched SharePoint servers’ content and the ability to execute code over the network.

Industry experts with over a decade of cybersecurity experience recognize that the old ways of doing risk assessment just don’t work anymore. You know what I mean? Those quarterly checklists and vulnerability scans that made us feel secure? They’re practically useless against today’s threats. Think about it. While you’re running your scheduled scan, attackers are already inside your network, mapping everything out.

BlackSuit ransomware combines data exfiltration and encryption, AsyncRAT spawns multiple forks, and HazyBeacon abuses AWS Lambda for command and control.

A newly disclosed vulnerability, CVE-2025-53770, has sent shockwaves through the enterprise IT and cybersecurity community. Affecting on-premises Microsoft SharePoint Server, this critical flaw enables unauthenticated remote code execution (RCE) through insecure deserialization of untrusted data. With a CVSS v3.1 score of 9.8, it represents one of the most severe threats to SharePoint deployments in recent years.
