Study Notes

Phishing Attacks

Phishing involves deceiving individuals by masquerading as legitimate entities to collect sensitive information such as usernames, passwords, and credit card details, primarily through email.
Common phishing tactics include using malware-infested attachments and links in emails that appear trustworthy.
Spear phishing targets specific individuals or companies by leveraging personal information to increase the likelihood of success.
Over 90% of security breaches are attributed to phishing attacks, highlighting its prevalence.
Clone phishing involves resending a legitimate email with a malware-laden attachment or link, falsely presenting it as an update.
Whaling targets high-level executives to gain access to critical business information, hence the term "whaling."
Link manipulation disguises malicious links under seemingly legitimate text or tabs, tricking users into clicking them.
Filter evasion tactics use images instead of text in phishing emails to bypass security filters.
Website forgery replaces the address bar of a phishing site with that of a legitimate site, deceiving users into entering sensitive information.
Covert redirect corrupts sites to display malicious pop-ups that redirect logins to hacker-controlled sites.
Social engineering employs deceptive practices to provoke users into clicking malicious links or visiting hacker websites.
Phone phishing uses calls or SMS messages to extract personal information from victims.

DoS and DDoS Attacks

Denial of Service (DoS) attacks disrupt network or device availability by overwhelming operational resources.
Distributed Denial of Service (DDoS) attacks utilize multiple compromised systems, such as botnets, to execute a DoS attack on a larger scale.
Buffer overflow vulnerabilities are frequently exploited in DoS and DDoS attacks, where malicious programs overwrite memory boundaries and disrupt operations.
Defense strategies against buffer overflow include randomizing memory layouts, leaving deliberate space between buffers, and monitoring memory writing actions.
Two prominent types of buffer overflow include stack overflow and heap overflow, which can lead to system vulnerabilities.
