• Phishing attacks – fake emails, messages, or websites designed to steal login credentials or personal information.
• Malware and ransomware – malicious software that steals data, encrypts files, or holds systems hostage for payment.
• Spyware and adware – software that secretly monitors activity or displays intrusive ads without user consent.
• Password theft and reuse – weak, reused, or stolen passwords make accounts easy targets for attackers.
• Unsecured Wi‑Fi networks – public or open Wi‑Fi connections can allow eavesdropping and man‑in‑the‑middle attacks.
• Fake software updates or downloads – attackers disguise malware as legitimate system updates or installers.
• Social engineering scams – manipulative messages, phone calls, or tech support scams trick users into giving access or money.
• Outdated software and operating systems – unpatched vulnerabilities can be exploited remotely.

• Data tracking and privacy erosion – aggressive tracking by websites, advertisers, or apps compromises user privacy.
• Cloud storage and data breaches – compromised accounts or insecure cloud services can expose personal or corporate information.

Even though Macs and PCs differ in architecture, both face these threats—Macs are not immune, just less frequently targeted. Keeping software updated, enabling multi‑factor authentication, and using reputable antivirus or endpoint protection tools greatly reduces these risks.
