Data Exfiltration: How Attackers Steal Information and How to Stop It

Data exfiltration often succeeds because organisations focus on perimeter defence while ignoring the silent movement of files across approved internal channels and trusted cloud services.

Stop Credential Leaks: 3 Immediate Actions to Secure Accounts

Most organisations lose control of credentials long before an attacker reaches the network perimeter, often through third-party service configurations rather than direct user error.

Prevent Stolen Session Tokens: Technical Controls and Detection

Session tokens often bypass password checks entirely, allowing attackers to maintain access even after you force a global credential reset across all user accounts.

Encryption vs Hashing: The Critical Difference for Data Security

Hashing destroys data irreversibly while encryption hides it temporarily, creating distinct risk profiles for credential storage versus data transit.

Cyber AttacksAll reports →

Which CIS Government And Utility Accounts Are At Risk From UAT-6275?

Espionage actors target CIS government and utility sectors with new WinRAR exploit and PowerShell chains, threatening interactive system access.

Which Chinese-language cybercrime ecosystem selling phishing kits did Microsoft dismantle?

Microsoft’s Digital Crimes Unit worked with law enforcement to disrupt a Chinese-language cybercriminal ecosystem selling illicit phishing tools.

Are Your Ivanti VPN Users at Risk From Chained Zero-Day Exploits?

Attackers used three flaws in Ivanti Connect Secure to gain root access, steal credentials and search for Active Directory data on affected networks.

Pretexting Prevention Checklist: Stop Social Engineering Attacks

Pretexting bypasses technical defences by exploiting human trust, making procedural verification more effective than software filters alone.

Privacy & PolicyAll reports →

Do intensified Russian VPN bans since mid-2025 heighten surveillance and operational risks?

Kremlin restrictions on VPNs and communications since mid-2025 raise surveillance and operational risks for organizations and individuals in Russia.

Does Flock CEO Garrett Langley believe crime reduction justifies privacy sacrifices?

Flock founder Garrett Langley argues that society must accept privacy trade-offs to reduce crime and insists that technological progress should not be paused.

Ad Tracking Pixels: How They Work and How to Stop Them

Ad tracking pixels operate invisibly within web pages to map your browsing habits across sites, creating profiles that outlast your session.

Cross-Border Data Transfers: Small Business Compliance Rules

Moving data across borders creates legal exposure even if you use standard cloud services without explicit written consent.

VulnerabilitiesAll reports →

Pre-authentication vulnerabilities: detection, exploitation and mitigation

Unauthenticated flaws bypass identity checks, allowing attackers to strike before credentials are verified or tokens are issued.

Vendor Patch Cycles: Why Timing Dictates Your Security Posture

Ignoring vendor release rhythms leaves systems exposed during the critical window between vulnerability disclosure and automated remediation.

Browser Extension Vulnerabilities: 7 Mistakes That Expose Your Data

Most extension breaches occur because developers trust user input and grant excessive permissions, turning a small tool into a persistent data leak.

Why Vulnerability Embargoes Matter for Security Operations

Coordinated disclosure prevents attackers from weaponising flaws before defences exist, turning a potential crisis into a controlled patch cycle.

Malware & RansomwareAll reports →

Disaster Recovery for Small Teams: Restore Operations Fast

Most small businesses fail recovery not due to lost data, but because they lack documented procedures for manual business processes during downtime.

Malicious Mobile Apps: Risks and Protection for Small Businesses

Mobile devices bypass network perimeter defences, allowing malware to harvest credentials and exfiltrate data directly from the device without triggering standard alerts.

Email Attachment Scanning: How It Works and What It Misses

Static scanning fails against fileless attacks, requiring sandboxing to execute code in isolation before delivery reaches the inbox.

Adware Risks for Small Businesses: Detection and Mitigation Strategies

Adware creates persistent network noise that masks genuine threats, forcing security teams to waste resources filtering benign but annoying traffic from actual attacks.

Threat IntelligenceAll reports →

Detection Engineering: A Practical Step-by-Step Implementation Plan

Most detection rules fail because they optimise for technical accuracy while ignoring the operational cost of alert fatigue and analyst burnout.

Pass-the-Hash Mistakes: 7 Config Errors That Hand Over Credentials

Your network allows lateral movement because default protocols trust cached hashes, not because attackers possess superior technical skill or novel exploit methods.

Strategic Threat Intelligence: Aligning Security Spend with Real Risk

Strategic intelligence shifts security from reactive patching to proactive risk management by revealing which adversaries actually target your specific industry and data assets.

User and Entity Behavior Analytics Mistakes That Blind Your Defenders

Misconfigured baselines create false positives that train defenders to ignore alerts, allowing genuine lateral movement to pass unnoticed during critical incident windows.
