Unmasking Cloud Identities: From Behavioral Clustering to Automated Detection

Unit 42 clusters behavior of 40,000+ AWS identities from 125 cloud environments to map functional roles and enable lightweight SQL-based detection.

Palo Alto Unit 42 built an unsupervised behavioral clustering model using UMAP and HDBSCAN on AWS CloudTrail logs to map cloud identities to functional roles such as administrators, backup services, security tooling and DevOps. The study analyzed over 40,000 identities across 125 cloud environments over two months. The researchers show that heuristics extracted from the clustering map can be implemented in standard SQL, enabling role classification at scale without running a continuous ML pipeline. The methodology extends to audit logs from other cloud providers, SaaS and Kubernetes.

Introducing Unit 42’s Attribution Framework

Unit 42 releases its Attribution Framework, a systematic method using Diamond Model and Admiralty scores to attribute activity clusters to named threat actors.

Palo Alto Networks' Unit 42 introduced a structured framework for threat actor attribution built on the Diamond Model of Intrusion Analysis and Admiralty reliability/credibility scoring. The framework tracks activity at three levels: activity clusters (named CL-STA, CL-CRI, CL-UNK, or CL-MIX), temporary threat groups, and named threat actors using the constellation naming schema. Analysts score evidence across TTPs, tooling, malware code, OPSEC, infrastructure, timelines, and victimology to decide when to merge or elevate clusters, avoiding premature group naming.

AD Rights Management Service (Part 1): Architecture, Deprecation, and Reconnaissance

Huntress maps AD RMS architecture and recon paths, setting up an offline key-extraction attack against its unrotatable 255-year root key.

Huntress's multi-part research examines Active Directory Rights Management Services, Microsoft's enterprise DRM role that still ships in Windows Server 2025 despite migration guidance favoring Azure Information Protection. Part 1 covers the trust model and how an ordinary domain account can locate RMS clusters and read rights-policy templates. Part 2 will detail four independent paths for extracting the Server Licensor Certificate (SLC) private key via service-group membership and the configuration database, enabling fully offline decryption of protected documents. The SLC certificate is valid from 2002 to 2258 and has no key-rotation mechanism, so a stolen key decrypts protected content indefinitely.

12 Best Kubernetes Security Tools Compared (2026): Features & Pricing

A buying-guide comparison of twelve Kubernetes security vendors, from free OSS tools like Falco and Kubescape to paid platforms led by Sysdig and Aqua.

The article compares features and pricing mechanics for twelve Kubernetes security vendors including Sysdig, Wiz, Aqua Security, SUSE NeuVector, Snyk, Isovalent (Cisco), Palo Alto Prisma Cloud, Fairwinds, Red Hat ACS (StackRox), and Tigera. It argues CNCF-grade open source (Kubescape, Falco, Calico, NeuVector, Cilium/Tetragon) provides a free floor for posture, runtime, and network policy. Pricing hinges on node-versus-cluster-versus-developer billing units, and Cisco's Isovalent acquisition consolidates the eBPF layer inside a networking giant.

12 Best Kubernetes Security Tools Compared (2026): Features & Pricing

GBHackers compares 12 Kubernetes security vendors including Sysdig, Wiz, Aqua, and Cisco Isovalent on features, pricing units, and procurement strategy.

GBHackers publishes a 2026 buying guide comparing 12 Kubernetes security vendors including Sysdig, Wiz, Aqua Security, SUSE NeuVector, Snyk, Cisco Isovalent, Palo Alto Networks, Fairwinds, Red Hat ACS, and Tigera. It argues CNCF-grade open source (Kubescape, Falco, Trivy, Calico, Cilium/Tetragon) provides free posture, runtime, and network policy coverage that resets price negotiations. Cisco's acquisition of Isovalent places the eBPF data plane under a networking giant, while the paid market focuses on multi-cluster policy, enforcement, and support. The piece emphasizes that pricing units (workload, node, cluster, developer, credits) heavily influence contract costs.

GBHackers compares pricing and features of 12 container security platforms, from free Trivy, Falco, and SUSE NeuVector to commercial Sysdig, Wiz, and Aqua.

A procurement-focused comparison of twelve container security vendors including Sysdig, Wiz, Aqua Security, SUSE NeuVector, and CrowdStrike, centered on billable units (per node, workload, developer, or vCore) and pricing mechanics. The piece argues free open-source tools like Trivy, Falco, and NeuVector set a floor that commercial products must justify exceeding through enforcement and scale. It also notes rising container threats, including Kubernetes flaws exploited to jump from containers to cloud accounts and exposed container registries.

TLD Tracker: Exploring Newly Released Top

Unit 42 tracked 19 newly released top-level domains and found large-scale phishing, unwanted program distribution, and cybersquatting tied to TLD launch dates.

Researchers analyzed 19 new generic TLDs, including .zip, .bot, .ing, and .meme, released or approaching general availability over roughly 18 months. Data from passive DNS, registry zone files, newly registered domain feeds, and the Tranco top-1M list showed phishing campaigns, potentially unwanted program distribution, and domain squatting on these TLDs. Abuse correlated with each TLD's rollout phases, indicating attackers monitor general availability dates to register and weaponize domains. The IANA root database now lists over 1,000 generic TLDs.

AD Rights Management Service (Part 2): Extraction, Offline Decryption, and the Unrotatable Key

Huntress research shows AD RMS SLC root key is unrotatable and never expires, so its compromise permanently exposes all RMS-protected documents.

Part 2 of Huntress's AD RMS series details server-side attacks: extracting the Server Licensor Certificate (SLC) private key and performing offline decryption of protected documents. The SLC key has no expiry or rotation mechanism, with a 255-year certificate validity (2002–2258), so whoever recovers it can decrypt every document the deployment ever protected, indefinitely. The author released SharpRMS, a unified tool combining the 2016 DisARMS client-side attacks with new server-side key extraction and decryption capabilities. The research frames the SLC as comparable to KRBTGT and the DPAPI domain backup key, though not equivalent to domain compromise.

Autoencoder Is All You Need: Profiling and Detecting Malicious DNS Traffic

Palo Alto Unit 42 details an autoencoder-based method that profiles DNS traffic to detect C2 and malicious domains, blocking ~374,000 malicious DNS requests daily.

Unit 42 built an RNN-based autoencoder that compresses DNS traffic time series into fixed-dimensional 'DNS profiles' for each domain and device. Downstream classification, clustering, and anomaly detection modules flag suspicious domains, capturing 170 emerging suspicious domains in May 2024. Signatures block roughly 374,000 malicious DNS requests daily and run in the Advanced DNS Security service, with detections shared to Advanced URL Filtering. Case studies link DNS traffic patterns to C2 beaconing, dynamic DNS abuse, and DNS tunneling for data exfiltration.
