The FY 2025 report found that 'exploitation of experts' was the most common tactic, with email being the top vector for initial contact. Adversaries from the East Asia and Pacific region were responsible for 48% of all reported incidents, using lures like paid consultations and fake job offers to gain access to sensitive U.S. technology and information.</p> <p><strong><a href="https://cyber.netsecops.io/articles/dcsa-report-foreign-spies-target-us-defense-industry-via-experts-and-email/" rel="noopener noreferrer">📖 Read full report →</a></strong></p> <h2> 8. Malicious Calendar Invite (ICS Phishing) Attacks Surge </h2> <p>Security firm Sublime has reported a staggering 33,000% increase in malicious calendar invite attacks, also known as 'ICS phishing,' between May and September 2026. Attackers are abusing .ics calendar files sent from legitimate services like Gmail to bypass email security filters. These invites, which are often automatically added to a user's calendar, contain malicious links that trick victims into downloading RMM tools like ScreenConnect, leading to device compromise, data theft, and potential ransomware deployment.</p> <p><strong><a href="https://cyber.netsecops.io/articles/malicious-calendar-invite-phishing-attacks-surge-33000-percent/" rel="noopener noreferrer">📖 Read full report →</a></strong></p> <h2> 9. AWS AgentCore Harness Credential Exfiltration Risk </h2> <p>Unit 42 researchers have uncovered a significant security issue in the default configuration of AWS AgentCore Harness, a managed runtime for AI agents. The vulnerability allows an attacker to use prompt injection to manipulate the agent into executing arbitrary commands through its built-in 'shell' tool. This tool, enabled by default with root privileges, operates in the same memory space where credentials from AgentCore Identity are handled in plaintext. Consequently, a successful prompt injection attack can lead to the exfiltration of sensitive credentials, bypassing IAM controls and encryption-at-rest. AWS has reviewed the finding and stated that securing against this is a customer responsibility under the shared responsibility model, advising users to scope allowed tools and use egress filtering.</p> <p><strong><a href="https://cyber.netsecops.io/articles/aws-agentcore-harness-credential-exfiltration-risk-via-prompt-injection/" rel="noopener noreferrer">📖 Read full report →</a></strong></p> <p>📌 <strong><a href="https://cyber.netsecops.io" rel="noopener noreferrer">Subscribe to daily updates at CyberNetSec.io</a></strong></p> <p>All reports include detailed analysis, IOCs, mitigation strategies, and references.</p> cybersecurity security threathunting threatintelligence NetSecOpsIO Thu, 17 Sep 2026 15:32:29 +0000 https://dev.to/netsecops_io/daily-cybersecurity-intelligence-september-17-2026-22ob https://dev.to/netsecops_io/daily-cybersecurity-intelligence-september-17-2026-22ob <p><em>Daily cybersecurity intelligence digest from <a href="https://cyber.netsecops.io" rel="noopener noreferrer">CyberNetSec.io</a></em> - September 17, 2026</p> <p>📊 <strong>8 threat intelligence reports</strong> covering vulnerabilities, exploits, threat actors, and security advisories.</p> <h2> 1.

The vulnerability affects both on-premises and cloud versions of the product. In response to the active exploitation, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added the vulnerability to its Known Exploited Vulnerabilities (KEV) catalog, mandating federal agencies to apply the patches by September 17, 2026. Cisco urges administrators to patch immediately and review network logs for signs of compromise, such as unexpected data transfers from affected gateways.</p> <p><strong><a href="https://cyber.netsecops.io/articles/cisco-patches-actively-exploited-zero-day-in-secure-email-gateway/" rel="noopener noreferrer">📖 Read full report →</a></strong></p> <h2> 2.

Iranian MOIS Uses HEAVYGRAM Malware via Telegram C2 </h2> <p>A joint advisory from the U.S., U.K., and Netherlands has exposed a cyber-espionage campaign by Iran's Ministry of Intelligence and Security (MOIS). The campaign uses a Windows malware called HEAVYGRAM (or CHOSEN BRICK) to spy on Iranian dissidents, journalists, and activists. A key feature of the malware is its use of the Telegram messaging app for command-and-control (C2), allowing operators to exfiltrate data and send commands covertly. The malware can copy emails, capture screenshots, and record audio, with the stolen information reportedly being published on pro-Iranian leak sites to intimidate victims.</p> <p><strong><a href="https://cyber.netsecops.io/articles/iranian-spies-use-telegram-controlled-malware-heavygram/" rel="noopener noreferrer">📖 Read full report →</a></strong></p> <h2> 6.

SPIFFE/SPIRE Identity Spoofing via cgroup Manipulation </h2> <p>Unit 42 researchers have detailed a post-exploitation technique allowing attackers with root access on a Kubernetes node to impersonate other workloads. The method involves spoofing Linux cgroup metadata to trick the SPIRE agent, a component of the SPIFFE machine identity framework, into issuing a valid SPIFFE Verifiable Identity Document (SVID) to a malicious process. This effectively allows the attacker to steal the identity of a legitimate, co-located service, potentially bypassing mTLS-based security controls and accessing sensitive data. The research highlights that the fundamental trust in the node is a critical security boundary. Unit 42 has released an open-source tool, 'Spooffe', to help defenders assess their exposure to this identity misuse vector.

The group operates a pay-per-install (PPI) marketplace, using YouTube gaming channels and search engine optimization (SEO) poisoning to lure victims into downloading a custom malware loader. This loader has been observed delivering a variety of payloads, including three recently analyzed strains: the newly dubbed Insomnia RAT, and the previously unreported ARKTunnel and Docro Hijacker. The campaign's success lies in its use of generic, disposable infrastructure that evades initial scrutiny, allowing multiple, unrelated threats to be deployed on a single compromised endpoint in enterprise and government environments.</p> <p><strong><a href="https://cyber.netsecops.io/articles/cl-cri-1171-ppi-network-uses-youtube-gaming-lures-for-malware-distribution/" rel="noopener noreferrer">📖 Read full report →</a></strong></p> <p>📌 <strong><a href="https://cyber.netsecops.io" rel="noopener noreferrer">Subscribe to daily updates at CyberNetSec.io</a></strong></p> <p>All reports include detailed analysis, IOCs, mitigation strategies, and references.</p> cybersecurity security threathunting threatactor NetSecOpsIO Tue, 08 Sep 2026 15:23:39 +0000 https://dev.to/netsecops_io/daily-cybersecurity-intelligence-september-8-2026-519f https://dev.to/netsecops_io/daily-cybersecurity-intelligence-september-8-2026-519f <p><em>Daily cybersecurity intelligence digest from <a href="https://cyber.netsecops.io" rel="noopener noreferrer">CyberNetSec.io</a></em> - September 8, 2026</p> <p>📊 <strong>8 threat intelligence reports</strong> covering vulnerabilities, exploits, threat actors, and security advisories.</p> <h2> 1.
