IBM and Red Hat recently released their annual Threat Intelligence Index, highlighting critical cybersecurity trends, including ransomware, infostealers, and industry-specific targeting. Key findings include:
– Identity-based attacks account for 30% of total intrusions.
– 4 out of the top 10 vulnerabilities frequently discussed on the dark web are linked to sophisticated threat actors.
– 26% of attacks on critical infrastructure exploit public-facing applications.
You Should Know: Practical Cybersecurity Commands & Steps
1. Detecting Identity-Based Attacks (30% of Intrusions)
- Linux: Use `auditd` to monitor user authentication:
sudo auditctl -w /etc/passwd -p wa -k identity-theft sudo ausearch -k identity-theft
- Windows: Check failed logins with PowerShell:
Get-EventLog -LogName Security -InstanceId 4625 -After (Get-Date).AddDays(-1)
2. Mitigating Dark Web-Exploited Vulnerabilities
- Scan for CVEs with
nmap:nmap --script vuln <target_IP>
- Patch Management (Linux):
sudo apt update && sudo apt upgrade -y
- Windows Patch Check:
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 10
- Securing Public-Facing Applications (26% of Critical Infrastructure Attacks)
– Check Open Ports:
netstat -tuln | grep LISTEN
– Harden SSH (Linux):
sudo sed -i 's/PermitRootLogin yes/PermitRootLogin no/' /etc/ssh/sshd_config sudo systemctl restart sshd
– Windows Firewall Rule for RDP:
New-NetFirewallRule -DisplayName "Block RDP Bruteforce" -Direction Inbound -Protocol TCP -LocalPort 3389 -Action Block
What Undercode Say
The IBM-Red Hat Threat Index underscores the need for proactive defense against identity theft, unpatched vulnerabilities, and exposed services. Key takeaways:
– Monitor authentication logs (/var/log/auth.log, Windows Event ID 4625).
– Automate patching (cron jobs, WSUS for Windows).
– Minimize attack surfaces (disable unused ports, enforce MFA).
– Use threat intelligence feeds (MISP, AlienVault OTX).
Expected Output:
Sample Linux CVE scan result (Trivy) trivy image --severity CRITICAL,HIGH nginx:latest
Windows exploit check (Sherlock) Find-AllVulns -OSVersion "Windows 10 2004"
