Protect Your Data & Stay Safe Online: Cybersecurity & Backup Guide

In today’s digital world, cybersecurity threats are evolving rapidly, and data loss can happen in an instant—whether from ransomware, hardware failure, or human error. On A Faster PC Live Technical Support, we recently covered critical cybersecurity threats and backup strategies to keep your data safe. Below, we break down the key takeaways in an easy-to-follow guide.

Why Backups Are Essential

Imagine waking up to find all your files encrypted by ransomware, your hard drive failed, or your backup was destroyed in a fire. Without a proper backup, recovering your data could be impossible—or cost thousands in recovery fees.

What Your Backup Should Protect Against

  1. Hardware Failure – Hard drives crash, motherboards fail, and SSDs wear out.
  2. Theft – If your computer is stolen, your backup shouldn’t be sitting right next to it.
  3. Fire & Natural Disasters – A backup in the same location is useless if everything burns down.
  4. Human Error – Accidentally deleting or corrupting a file? Roll back to a previous version.
  5. Ransomware – Hackers encrypt your files and demand payment. A backup lets you restore without paying.
  6. Sabotage – Disgruntled employees or hackers may intentionally delete data.

Backup Solutions That Work

  • Manual Copies (Not Recommended) – Requires discipline, easy to forget, and doesn’t protect against ransomware.
  • Cloud Backup (OneDrive, Google Drive) – Convenient but limited (e.g., 30-day version history). Hackers can delete cloud files if they access your account.
  • Managed Cloud Backup (Best for Businesses) – Automatic, encrypted, off-site backups with long-term version history (years, not just weeks).

Example: Restoring Files with OneDrive

If a file is corrupted or encrypted by ransomware:

  1. Right-click the file in OneDrive.
  1. Select Version History.
  2. Restore a previous unencrypted version.

(Note: This only works if the ransomware hasn’t already encrypted older versions!)

6 Critical Cybersecurity Threats You Must Patch Now

Cybercriminals are actively exploiting these vulnerabilities. If you use any of these systems, update them immediately:

1. Fortinet Firewall Exploit (Active Attacks!)

  • Risk: Hackers can take over your network via a SQL injection flaw in the HTTP authorization header.
  • Impact: At least 160 systems were compromised in 48 hours (July 14–15).
  • Fix: Install Fortinet’s latest security patches.

2. Cisco Identity Services Engine (ISE) Vulnerability

  • Risk: Attackers can execute arbitrary code with root access (full control of your system).
  • How: Sending a malicious API request.
  • Fix: Patch Cisco ISE immediately—even though no attacks are reported yet, they’re coming.

3. Windows Server 2025 "Golden DMSA" Attack

  • Risk: Hackers can generate passwords for any Delegated Managed Service Account (DMSA) in Active Directory.
  • Impact: Enables stealthy lateral movement (hackers jumping from system to system).
  • Fix: Apply Microsoft’s latest updates.

4. Google Chrome Zero-Day Exploit (Active in the Wild)

  • Risk: Malicious websites can escape Chrome’s sandbox and run arbitrary code.
  • How: Exploits flaws in ANGLE & GPU components.
  • Fix: Update Chrome immediately.

5. SonicWall SMA Appliances Under Attack

  • Risk: Hackers (UNC 6148 group) are stealing admin credentials and gaining shell access via SSL VPN.
  • Fix: Monitor for suspicious activity—even fully patched systems may be at risk.

6. eSIM Vulnerability in IoT Devices

  • Risk: Attackers with physical access can extract cryptographic keys from eSIM chips.
  • Impact: Affects smartphones, medical devices, and industrial systems.
  • Fix: Check for firmware updates from manufacturers.

How to Protect Yourself

  1. Enable Automatic Updates – For OS, browsers, firewalls, and firmware.
  2. Use a Managed Backup Solution – Don’t rely on manual backups.
  3. Enable Multi-Factor Authentication (MFA) – Prevents unauthorized account access.
  4. Train Employees on Phishing – Many attacks start with a malicious email.
  5. Work with a Cybersecurity Expert – If managing this sounds overwhelming, get professional help.
