Phishing attacks
Fake emails, sites, and messages that steal your credentials
Critical

Phishing is the most common cyberattack. Attackers impersonate trusted brands — banks, Google, PayPal — to trick you into entering your password or clicking a malicious link that installs malware. Spear-phishing targets you specifically using personal data.

How to protect yourself:
  • Check the sender domain exactly — one letter can differ
  • Hover over links before clicking to reveal the real URL
  • Never enter passwords via an email link — navigate directly to the site
  • Report phishing emails to your email provider
Ransomware
Malware that encrypts your files and demands payment to restore them
Critical

Ransomware locks you out of your own files and demands cryptocurrency payment to restore access. It spreads via email attachments, malicious downloads, and unpatched software vulnerabilities. Organisations lose millions of dollars per incident.

How to protect yourself:
  • Maintain regular offline or cloud backups — the 3-2-1 rule
  • Never open email attachments from unknown senders
  • Patch your OS and all software promptly
  • Use endpoint protection software with behavior monitoring
Man-in-the-middle (MITM) attacks
Intercepting your traffic on unsecured networks
High

On public Wi-Fi, an attacker can position themselves between you and the internet — silently reading passwords, session cookies, and personal data if the connection is unencrypted. Coffee shops and hotels are common attack locations.

How to protect yourself:
  • Always use a VPN on public or untrusted Wi-Fi
  • Only visit HTTPS sites — look for the padlock in your browser
  • Enable HTTPS-Only mode in your browser settings
  • Avoid banking or logging into sensitive accounts on public networks
Data broker exposure
Your personal information sold to third parties without your knowledge
High

Data brokers scrape and sell your name, address, phone number, income estimate, and browsing habits. This data fuels spam, scams, identity theft, and highly targeted phishing campaigns — and most people have no idea it is happening.

How to protect yourself:
  • Use a removal service like DeleteMe or Incogni to opt out at scale
  • Use email aliases so your real address never reaches data brokers
  • Regularly Google your own name to find exposed profiles
  • Opt out via Google's "Results about you" tool
Social engineering
Psychological manipulation used to gain access or extract information
High

Social engineers exploit trust rather than technology — impersonating IT staff, executives, or known contacts to trick people into revealing credentials, sending money, or granting system access. Urgency and authority are the main psychological levers.

How to protect yourself:
  • Verify unexpected requests through a separate, trusted channel
  • Never share passwords or 2FA codes — legitimate staff never ask
  • Be especially skeptical of any "urgent" or "act now" pressure
  • Report suspicious requests to your security team immediately
Stalkerware & spyware
Hidden software that silently monitors your device and activity
Medium

Stalkerware and spyware run invisibly in the background, logging keystrokes, reading messages, and tracking GPS location. They are often installed by someone with physical access to your device. Victims are frequently unaware for months.

How to protect yourself:
  • Audit installed apps regularly — investigate any you don't recognise
  • Check for unusual battery drain or data usage as warning signs
  • Use a mobile security scanner like Malwarebytes
  • Factory reset your device if you have strong reason to suspect compromise
Credential stuffing
Using leaked username/password pairs to break into other accounts
Medium

When any service is breached, attackers dump the credentials and automatically try them across hundreds of other websites. If you reuse passwords, a breach on one site hands attackers access to all your accounts that share the same password.

How to protect yourself:
  • Use a unique password for every single account
  • Check if you've been breached at haveibeenpwned.com
  • Enable login alerts on all important accounts
  • A password manager makes unique passwords effortless
Fake software & malicious downloads
Disguised malware distributed through unofficial app sources
Medium

Cracked software, pirated games, and unofficial app stores are loaded with trojans, cryptominers, and keyloggers. Attackers also poison search ads to push malicious downloads for popular tools. Even legitimate-looking installers can be compromised.

How to protect yourself:
  • Only download software from official sites or your device's app store
  • Verify software checksums (SHA-256) when provided by the developer
  • Never run software from pop-up ads or unexpected search results
  • Scan downloaded files with VirusTotal before opening
