How to secure your Wi-Fi network from cyber threats

Think your Wi-Fi is safe because it’s “hidden”? Think again. SSID hiding is a speed bump, not a wall. Use strong WPA3 encryption, update your router firmware, and disable WPS. Real security means layers, not illusions. Your pentest toolkit will thank you. 🔐 #WiFiSecurity #PentestTips

🚨 A HIGH severity buffer overflow (CVE-2025-12596) affects Tenda AC23 routers (firmware 16.03.07.52). Public exploit disclosure means attackers could remotely compromise devices—potentially leading to network breaches and downtime. Immediate steps: check for firmware updates, restrict management access, disable remote admin, and segment critical assets. Monitor for unusual activity and educate users on risks of exposed interfaces. Act now to protect your network! https://lnkd.in/d83mUPcv #OffSeq #NetworkSecurity #Vulnerability #RouterSecurity #InfoSec

A CRITICAL buffer overflow vulnerability (CVE-2025-60553) affects D-Link DIR600L Ax routers, firmware FW116WWb01. Attackers can remotely exploit the curTime parameter in WAN setup, risking device takeover, network compromise, and denial of service. No patch yet. Immediate steps: restrict remote access, monitor for suspicious traffic, apply firewall rules, and segment networks. Consider device replacement if patch delays persist. Stay alert for updates from D-Link. https://lnkd.in/dbN5mFjH #OffSeq #InfoSec #NetworkSecurity #Vulnerability #IncidentResponse

A HIGH-severity stack-based buffer overflow (CVE-2025-13190) affects D-Link DIR-816L routers running firmware 2_06_b09_beta. Remote attackers can exploit the vulnerable /portal/__ajax_exporer.sgi endpoint for full device compromise—public exploits are available. 🚨 No official patch exists as the product is unsupported. Immediate hardware replacement is strongly advised. If not possible, isolate affected routers, restrict access, monitor for exploitation, and deploy IDS/IPS for detection. Protect your network and users—don't ignore this risk! More info: https://lnkd.in/du5dQuEH #OffSeq #NetworkSecurity #Vulnerability #IoTSecurity #IncidentResponse

VoIP How-To: Stop Chasing Ghost Calls 👻   Ever had a client complain about “phantom rings” or random calls that don’t exist? It’s not a haunting — it’s usually a SIP misconfiguration.   Here’s how MSPs can squash ghost calls fast: ✦ Lock down firewalls – Only allow traffic from known, trusted IPs. ✦ Update device firmware – Old firmware = open doors. ✦ Educate end users – Teach them to report patterns, not just one-offs.   💡 Pro tip: A quick config audit usually solves ghost calls before they turn into ticket nightmares.   ⇢ What’s the weirdest VoIP “mystery issue” you’ve had to troubleshoot?

Curious how Mac can keep business data secure? From reservation systems to staff schedules, Apple builds security into every layer. FileVault encrypts every file, keeping sensitive information safe even if a device is lost or stolen. System Security Mac creates a secure chain of trust by designing processor, firmware, OS, and software together. This reduces security risks and ensures emails, customer records, and payment information remain confidential, even when accessed remotely. Network Security Authenticated, authorised, and encrypted connections protect data as it travels across networks keeping information safe on the move. Data Security With FileVault encryption, every file is secure. Without the correct password, data remains inaccessible even if the disk is removed and connected to another device. #AppleForBusiness #MacSecurity #DataProtection #RyujinElectronics #CanberraBusiness
