SPF validation stops at the final hop, leaving your domain vulnerable to spoofing once mail traverses third-party servers.

Cyber hygiene is the preventative maintenance of systems, whereas cyber security is the active defence against external threats.

SPF records prevent attackers from forging your domain name in the sender field, stopping many phishing attempts before they reach the inbox.

New malware creates hidden browser instances using victim authentication data, bypassing screen mirroring to access live sessions remotely.

Attackers allegedly altered settings in French stores, raising temperatures to 50°C and forcing the disposal of perishable goods.

Researchers found two edge cases in internationalized domain name handling that allow convincing lookalike domains to bypass Chromium’s Unicode safeguards.

The operator of a major illicit marketplace faces decades in prison and asset forfeiture after facilitating hundreds of millions in illegal trades.

The National Cyber Security Centre is collecting details on how organisations select external attack surface management tools to improve its advisory services.

Dedicated servers lack the natural traffic absorption of cloud platforms, making network-layer filtering and capacity planning the primary defences against volumetric denial of service attacks.

Attackers steal active session tokens to access accounts without credentials, rendering traditional login security measures ineffective for that duration.

Japan’s national cybersecurity hub chief declares a state of emergency after more than twenty major firms report data breaches in recent weeks.

Cloudflare expands Clef with a multimodal model handling audio, video, images and text, while boosting speed and cutting prices.

Defences fail because they assume linear progression, whereas modern adversaries move laterally through trusted internal paths before exfiltrating data.

Privileged access management often fails because teams secure the login but ignore the session, leaving lateral movement open even when credentials are rotated daily.

Border Gateway Protocol relies on trust between networks, meaning a single misconfiguration can silently divert traffic without triggering traditional security alerts.

Physical observation bypasses digital defences entirely, making your office layout and user habits the primary vector for credential theft.

Relying on account lockout policies alone creates a denial-of-service vector that attackers exploit to disrupt legitimate user access.
