Study Notes

Many cyber security breaches are caused by human behavior, not technical vulnerabilities.
This presentation covers how hackers exploit human weaknesses.
Safe WiFi network use is critical to avoid attacks.
Vishing, clickjacking, spoofing, and phishing are social engineering techniques.
Ransomware is a type of malware that prevents or limits access to systems, often by encrypting files.

Social engineering manipulates people into performing actions or divulging confidential information.
It's based on cognitive biases (human decision-making errors).
Techniques include phishing, vishing, pretexting, and clickjacking.
Phishing involves sending deceptive emails to gain sensitive information.
Vishing uses phone calls to impersonate legitimate entities.
Pretexting involves impersonating another person to gain information.
Clickjacking tricks users into clicking on something different from what they intend.

Ransomware

Ransomware prevents access to systems, often by encrypting files.
Most ransomware is crypto-ransomware.
Users are forced to pay a ransom for the decryption key.
Ransomware can be downloaded from malicious websites and emails with attachments.
Ransomware can spread through malvertisements (malicious advertisements).

Don't panic when receiving notifications, emails, warnings, or calls.
Examine the website links provided in emails to ensure authenticity.
Check details like sender's email address and domains.
Check for fake websites and logos.

Spoofing

Caller ID and email spoofing deceive users into providing credentials.
Phone numbers can be spoofed to make calls appear to come from a different source.
This can be used in scams requesting payment.

Email Spoofing

Spoofing is as easy as faking physical mail.
The "From" address in an email can be easily altered to make the email look legitimate.

Ransomware Defense

Immediately remove malware if suspected.
Disconnect and shut down systems to prevent spread.
Use antivirus and maintain offline backups to avoid data loss.
Do not pay the ransom. There is no guarantee the data will be recovered, and it might encourage more attacks.
