    Study Notes

    Threat Vectors and Attack Surfaces

    • Message-based attacks:

      • Emails are a common vector for phishing, malware, and spam.
      • Spear phishing emails mimic trusted sources, often containing malicious attachments or links.
      • Look for poor grammar, misspellings in emails to detect phishing attempts.
      • SMS messages can also lead to phishing sites or malware download.
      • Fake bank messages requesting urgent verification are common examples.
      • Enable two-factor authentication to enhance security.
      • Instant messaging platforms (WhatsApp, Telegram, Signal) can spread misinformation or malicious links.
      • Be cautious of files or links from known contacts; verify the legitimacy outside the platform.

    • Image-based attacks:

      • Images can conceal malware or link to malicious sites.
      • Steganography can hide malicious code within images.
      • Ensure security software scans images for hidden payloads.

    • File-based attacks:

      • Files (PDFs, Word documents) can contain embedded scripts or macros that execute malicious code upon opening.
      • A seemingly harmless invoice could release ransomware.

    • Voice call attacks (Vishing):

      • Scammers posing as tech support or other trusted entities to obtain personal information.

    • Removable Device attacks:

      • USB drives, CDs, and other removable devices can carry malware.
      • Malware can auto-execute upon connection.
      • Disable auto-run features and scan removable media before use.

    Vulnerable Software

    • Client-based vs. Agentless:
      • Client-based software requires installation and is vulnerable if not updated regularly.
      • Agentless software runs in the cloud and can be vulnerable if unpatched.
      • Regularly update software and run vulnerability scans.

    Unsupported Systems and Applications

    • Risks:

      • Using outdated or unsupported software increases risk of unpatched vulnerabilities being exploited.

    • Mitigations:

      • Switch to supported software or isolate unsupported systems from the network.

    Unsecure Networks

    • Wireless attacks:

      • Open or poorly secured Wi-Fi networks are susceptible to man-in-the-middle attacks.

    • Wired attacks:

      • Even wired networks can be compromised via physical access or unsecured ports.

    • Bluetooth attacks:

      • Bluetooth can be exploited (bluejacking/bluesnarfing) where unauthorized users send messages or steal information.
      • Encrypt network traffic, disable unused ports, and services.

    Open Service Ports

    • Risks:

      • Open ports are vulnerable to attackers gaining unauthorized access.

    • Mitigations:

      • Close unnecessary ports and implement proper access controls.

    Default Credentials

    • Risks:

      • Systems with default usernames and passwords are at high risk of unauthorized access.

    • Mitigations:

      • Always change default credentials and use strong, unique passwords.
      • Use a password manager to keep track of complex passwords.

    Supply Chain Attacks

    • Managed Service Providers (MSPs):

      • MSPs manage services but can be compromised, impacting clients.

    • Vendors/Suppliers:

      • Third-party software, hardware, and even chip manufacturers can be compromised.

    Human Vectors/Social Engineering

    • Social engineering targets human behavior to extract information or gain unauthorized access.

    Types of attacks

    • Phishing: Via email.
    • Vishing: Over the phone.
    • Smishing: Via SMS.

    General Security Best Practices

    • Educate your team regularly on security best practices.
