This article explains the differences between common malware types—virus, worm, trojan, rootkit, and fileless threats—and emphasizes why correctly identifying them matters for incident response and CISSP exam preparation. It also outlines typical infection vectors and basic defenses like backups, updates, and disabling macros. #Virus #Worm
Intezer’s 2026 AI SOC Report analyzes 25 million operational alerts and shows that SOCs routinely miss real threats hidden in low-severity alerts and that EDRs frequently report “mitigated” while endpoints remain compromised. The write-up recommends AI-augmented forensic triage, reassessing phishing defenses for browser-based attacks, and cleaning cloud misconfigurations to close these coverage gaps. #Intezer #S3 #CloudflareTurnstile #Vercel
Shai-Hulud 2.0 revealed that pre-install execution hooks and hijacked CI/CD runners can weaponize package installs to harvest cloud credentials and persist by enrolling self-hosted GitHub runners. Preventing a Shai-Hulud 3.0 requires moving control away from individual developers to a curated, built-from-source catalog with SLSA-hardened provenance and cryptographic pinning for reliable, organization-wide open-source consumption. #ShaiHulud2 #ActiveState
Clover Security embeds AI agents into the design and architecture phase to catch business logic and architecture risks that traditional downstream AppSec tooling misses. The platform’s Memory Agent, Feature Context Graph, and agent fleet automate design reviews, detect implementation drift and AI-generated code risks, and have delivered measurable coverage and speed gains for customers. #CloverSecurity #Neo4j
The Cybersecurity Club runs a six-week Discord mentorship program that pairs learners with experienced practitioners to build hands-on skills, earn certifications, and advance careers. Participants follow a structured weekly check-in routine and can join as mentees or mentors across topics like penetration testing, Red Team work, SOC skills, and certification preparation. #CISSP #Wireshark
This guide walks through a real-world PostgreSQL penetration testing workflow from reconnaissance to post-exploitation, demonstrating scanning, authentication attacks, file reads, command execution, and reverse shells using practical examples. It also outlines Metasploit and client-based techniques, credential attacks, and actionable hardening and remediation steps to secure PostgreSQL deployments. #PostgreSQL #Metasploit
Identity-based attacks increasingly begin with valid credentials, making a unified identity defense layer that combines privileged access management (PAM) and identity threat detection and response (ITDR) essential for organizational resilience by 2026. This integrated approach detects anomalous identity behavior, enables automated remediation, and supports Zero Trust and compliance frameworks—illustrated by incidents like the FICOBA breach and solutions such as Syteca. #FICOBA #Syteca
Digital signatures ensure data integrity and authenticity by hashing content and signing the hash with a private key so recipients can verify it with the corresponding public key. This article explains the signing and verification steps and includes a quick Docker lab using OpenSSL to create and test signatures yourself. #OpenSSL #Docker
Most security programs are uneven after years of reactive, compliance-driven purchasing, leaving unmapped gaps that represent the highest business risk. This workshop teaches how to map controls across the NIST Cybersecurity Framework and apply the TaSM (Threat and Safeguard Matrix) to identify critical gaps and prioritize remediation. #NISTCybersecurityFramework #TaSM
The traditional seat‑based SaaS model that delivered predictable ARR and high valuations is stalling as growth slows and investors demand profitability. AI is rapidly extending task time horizons and shifting value from humans-in-the-loop to autonomous agents, forcing a rethink of seat pricing and tool stacks. #Wiz #ClaudeOpus
The Cybersecurity Pulse highlights a global Microsoft Intune-based attack that Handala says wiped devices and exfiltrated vast data from Stryker, causing widespread operational disruption. It also reviews AI-driven security innovations, major startup funding, and shrinking time-to-exploit trends that pressure teams to prioritize patching and attack surface reduction. #Handala #Stryker #MicrosoftIntune #VoidManticore
Linux is presented as the foundation for cybersecurity work because most servers, cloud infrastructure, containers, and many devices run on Linux, making a practical understanding of the OS essential for testing, hardening, monitoring, and forensics. The guide then lays out a three-phase roadmap—from beginner-friendly GUI distributions to command-line mastery and security-focused…
Hack The Box (HTB) Academy provides hands-on, real-world labs and structured learning paths that let beginners grow into skilled ethical hackers. Modules are unlocked with cubes—the platform’s currency—with a 50-cube starter bonus via Cybersecurity Club, plus job-role and skill paths and a deep offensive security catalog that progresses from free Tier…
This article helps cybersecurity beginners focus on the five most important network protocols and understand why they matter in real-world security, starting with the TCP/IP model and HTTP basics. It explains the differences between TCP and UDP, the role of SMTP/IMAP/POP3 and FTP in secure communications, and why mastering these basics…
