Understanding Common Cyber Threats & How to Stay Safe

Malware, Viruses and Ransomware

Strong cybersecurity starts with understanding different forms of malicious software that threaten individuals and organizations.

• Malware: A broad term for harmful software designed to infiltrate, damage or disable devices and networks. 
• Viruses: A type of malware that copies itself and spreads across systems, often attaching to “host” files. 
• Ransomware: A particularly dangerous form of malware that encrypts your files or systems and demands payment for decryption. In 2024, ransomware attacks accounted for 35% of all cyberattacks. 
• Infostealers / Credential theft: Malware that collects login credentials, personal data or other sensitive information to be used or sold later. 

Phishing

Phishing remains one of the most effective cyber-attack methods because it takes advantage of human trust and error. 

• Phishing (email): Attackers send fake emails designed to trick you into clicking malicious links, downloading attachments or sharing login details.
  • Spear phishing: A more targeted version where attackers use personal or company-specific info to appear more credible. 
• Smishing / SMS phishing: Attackers send fake text messages asking victims to click malicious links or fake alerts (e.g. “Your bank account is locked”).
• Vishing / voice phishing: Attackers call posing as legitimate organizations and ask for password codes or other sensitive information.

According to data from trend reports, phishing attacks have surged with the rise of AI tools. Security reports also suggest 80–95% of human-associated breaches start with phishing. 

How to Stay Alert and Recognize Suspicious Activity 

Preventing damage often begins with awareness. Here are key habits to cultivate:

• Always double-check the sender’s email address—look closely for typos or odd domains.
• Be suspicious of emails or texts that create urgency (e.g., “Your account will be closed!”). 
• Hover—don’t click—over links to inspect the actual URL before clicking. 
• Don’t trust unsolicited attachments, especially ZIP, .exe, or macro-enabled files. 
• If unsure, verify through an independent channel: call the supposed sender using a known number, or log in manually by opening a separate browser window (don’t use the link). 
• Be cautious of unknown phone numbers, especially if they ask for codes, passwords, or remote access. 
• Use multi-factor authentication (MFA), also known as two-factor authentication (2FA), on all accounts whenever possible. 

Even small behaviors, like using strong, unique passwords for each account and updating software, help reduce your risk. 

Strengthening Security at Home and on Your Network

Beyond individual caution, network-level protections can serve as an additional line of defense.  

• Router-level security (ProtectIQ): 
  • Scan traffic with ProtectIQ, a firewall protection built into MidSouth Fiber’s GigaSpire router, in real time to block viruses, malware and suspicious web activity before it ever reaches your devices. 
    • In one month alone, the system intercepted over 135,000 threats targeting subscriber networks. 
  • Monitor blocked threats with the MidSouth Fiber app, giving insight into what attempts occurred.
• Device & access control (ExperienceIQ / App tools):
  • Monitor unrecognized devices and remove from your network. 
  • Block unwanted websites or set time limits per device.
  • Create guest networks for visitors to keep primary network secure.  
  • Prioritize connections for critical devices or tasks. 
• Keep firmware and systems updated: Regularly update routers, devices and other connected systems to fix known security flaws and stay protected. 
  • MidSouth Fiber automatically updates our GigaSpire router to ensure your home is protected with up-to-date firewall protection. 
• Monitor logs and alerts: Take advantage of activity logs and alert systems to see patterns of blocked threats—this visibility helps you understand attack methods and adjust defenses. 

Maintain Ongoing Caution 

Cybersecurity isn’t a one-and-done project. Attackers evolve, as do the tools they use.

• Commit to periodic review of your network security settings.
• Discuss how to recognize phishing and suspicious behavior with all household members or employees. 
• Use simulation tools or awareness programs to keep detection skills sharp.
• Back up your data regularly and store copies offline or offsite.
• Designate limited access to nonessential devices or accounts to ensure system changes are made by trusted devices. 

Staying Ahead of Cyber Threats Starts with Awareness

With cyberattacks continuously on the rise, awareness is the best defense. By understanding malware, phishing tactics, and how attackers manipulate human trust, you can stay more alert. Pair with proactive network protections, like router-level blocking and device control, and you’ll build a far stronger shield around your home or business.
