Attack Chains, Not Just Attack Surfaces: Why Testing Individual Techniques Misses the Point
IntroductionSecurity teams have gotten pretty good at testing against what can hurt them. Can this EDR agent catch this payload? Will my organization fail the phishing simulation? Does this SIEM rule fire on this particular technique? And, in more mature organizations, this testing happens continuously rather than as a one-off exercise.But no matter how much…

12 Best Ransomware Protection Solutions Compared (2026): Features Pricing
Quick Answer: No single product stops ransomware. The strongest stacks combine EDR prevention (CrowdStrike, SentinelOne, Microsoft Defender, Sophos, Bitdefender), managed eyes-on-glass (Huntress, Sophos MDR), and guaranteed recovery (Rubrik, Acronis). Note: ColorTokens is microsegmentation and Rubrik is cyber resilience containment and recovery layers, not EDR. Ransomware is now a professionalized industry double-extortion ransomware operations, hands-on-keyboard operators,…

The Gentlemen Ransomware Hackers Use TukTuk C2 to Steal Credentials and Disable EDR Security
Tags: breach, control, credentials, cyber, edr, framework, group, hacker, healthcare, ransomware, technologyThe Gentlemen ransomware operation has been linked to a previously undocumented, cross-platform command-and-control framework named TukTuk, alongside EDR-disabling tooling, DLL sideloading research, and datasets apparently stolen from technology and healthcare organizations. Analysis of a Finland-hosted server identified what researchers assess as the complete TukTuk development project, providing an unusually detailed view into the group’s post-compromise capabilities.…

Credential Security: What Endpoint Protection Really Means for Secrets
TL;DREndpoint protection means AV or EDR: The term “endpoint protection” almost always refers to antivirus or EDR. Antivirus started as signature-based malware detection; EDR added continuous behavioral monitoring and response. Both are designed to detect and stop malicious activity on… First seen on securityboulevard.com Jump to article: securityboulevard.com/2026/09/credential-security-what-endpoint-protection-really-means-for-secrets/

Measuring detection coverage against MITRE ATTCK using DeTTCT
For many UK SMEs, the hardest part of detection engineering is not writing alerts. It is knowing whether the alerts you already have actually cover the techniques that matter. A SIEM or XDR platform can produce a lot of noise, but without a structured way to measure coverage you can end up with false confidence….…

Stop Building a 2003 SOC with AI: Local Context, Failure Modes and Your Path (Part 3)
In Part 1 of this series, we dumped a pile of uncomfortable questions on you and promised answers. In Part 2 of the series, we talked about why 1990s-2000s alert triage must die. The core thesis, if you recall: if you add AI agents into a legacy, swivel-chair SOC structure, you are essentially building a robotic…

Windows Defender Driver Abuse Enables Kernel-Level EDR and Antivirus Bypass
Security researcher Jiřà Vinopal has published a detailed analysis of BTR.sys, the Microsoft Defender Boot-Time Removal driver. His research reveals how this legitimate, Microsoft-signed component can be exploited to perform file and registry operations under attacker control from kernel mode. This study, titled >>BTR Reforged,<< does not rely on traditional memory-corruption vulnerabilities or the Bring…

The Art of Detonating Malware: Lessons from a Research Lab
Modern ransomware operators are no longer content to simply encrypt data and hope for a payout. They are actively working to evade every layer of enterprise defense, from sandboxes and EDR to backup infrastructure itself, using techniques observed in Cohesity’s in-house REDLab malware research environment. For security leaders, backup and recovery systems can no longer..…

Microsoft Defender XDR Blind Spot Lets Public C2 Traffic Evade Detection Queries
Microsoft Defender XDR users may inadvertently overlook command-and-control (C2) traffic when searching for Internet-bound connections due to a specific behavior in how IP addresses are classified. This issue arises from Kusto Query Language (KQL) detections that depend solely on filtering by RemoteIPType == >>Public<< in the DeviceNetworkEvents table. As a result, traffic destined for public…

SindriKit 1.3.0 Abuses Call Stack Spoofing to Bypass EDR Detection
SindriKit 1.3.0 introduces a significant advancement in evading Endpoint Detection and Response (EDR) systems by exploiting dynamic call stack spoofing. This method defeats telemetry that inspects kernel-transition call chains, going beyond just user-mode hooks. Previously, SindriKit 1.2.0 had already separated syscall invocations via indirect syscalls, redirecting to legitimate syscall return instructions in ntdll.dll to evade…
