- Denial of Service attacks flood resources, rendering services unavailable.
- Dictionary attacks utilize common passwords to gain unauthorized access.
- URL interpretation modifies URLs to access restricted pages.
- File inclusion attacks exploit vulnerable web servers to access sensitive files.
- Man-in-the-middle attacks intercept and manipulate communication between parties.
System-Based Attacks
- Viruses, self-replicating malware, spread without user knowledge and can cause system damage.
- Worms replicate to infect uninfected computers, often via email attachments.
- Trojan horses disguise themselves as legitimate software, executing malicious activities in the background.
- Backdoors provide unauthorized access, bypassing standard authentication.
- Bots automate tasks and can be used for both benign and malicious purposes.
- Active attacks alter data on the target or during transmission (e.g., masquerade, session replay, message modification).
- Passive attacks involve monitoring traffic without altering data (e.g., eavesdropping, traffic analysis).
Social Engineering
- Social engineering manipulates human behavior to acquire sensitive information.
- Attackers exploit emotional triggers like fear, curiosity, and urgency to deceive victims.
- Trust is established through rapport-building techniques to facilitate information disclosure.
- The attack cycle involves preparation, infiltration, exploitation, and release.
Cyber Stalking
- Cyberstalking involves using digital tools to harass or intimidate victims.
- Stalkers may engage in unwanted messaging, hacking accounts, or impersonating victims.
- The consequences can include legal repercussions, mental health issues, reputational damage, and invasion of privacy.
Types of Cyber Stalking
- Webcam hijacking enables unauthorized access to victim’s cameras.
- Social media monitoring allows stalkers to track location check-ins.
- Catfishing involves creating fake profiles for deception.
- Geotagging in digital photos aids stalkers in tracking victims' whereabouts.

- Anonymity in cyber cafés may enable illegal activities, including online fraud and drug trafficking.
- Lack of privacy exposes users to monitoring and tracking of their activities by others in the café.
Challenges in Managing Cyber Crimes
- Users often remain anonymous in cyber cafés, complicating the tracing of illegal activities.
- Cyber cafés frequently lack essential security measures, such as antivirus software and firewalls.
- Limited resources hinder effective monitoring of potential illegal activities within the café.
- Inadequate laws and regulations in some areas create gaps in responsibilities for preventing cybercrime.
Preventive Measures
- Verifying user identities before granting access can help track and deter illegal actions.
- Regular updates and maintenance of computers and networks enhance protection against vulnerabilities.
- Installing security software like antivirus programs is crucial for detecting and preventing cyber threats.
- Monitoring software and surveillance systems aid in identifying suspicious behavior in cyber cafés.
- Educating users on safe internet practices can significantly reduce the risk of cybercrime.
- Compliance with local laws regarding internet use and data protection strengthens the café's security protocols.
Botnets
- A botnet is a network of infected devices controlled by cybercriminals via malware without user awareness.
- Botnets are commonly used for sending spam, creating unusual internet traffic, and launching attacks.
- Two primary control methods exist for botnets: client-server (centralized) and peer-to-peer (decentralized), with the latter being more difficult to track.
- Zeus malware, known to have infected millions of hosts, exemplifies botnet exploitation.
- Common botnet uses include DDoS attacks, spamming, traffic sniffing, keylogging, and identity theft.
Attack Vectors
- An attack vector is the method used by cybercriminals to infiltrate systems and exploit vulnerabilities.
- Attackers can steal sensitive information such as financial data and personal identification numbers through vectors.
- Active attacks involve direct system interference, while passive attacks utilize discreet infiltration without detection.
- Mitigating attack vectors includes avoiding suspicious emails and calls, and utilizing robust security solutions.
Cloud Computing
- "Cloud" refers to a network that provides services over the internet, available through public and private networks.
- Cloud computing enables remote manipulation and access to hardware/software resources, facilitating online data storage and application use.
- Four deployment models exist: public, private, community, and hybrid clouds.
- Cloud computing relies on three service models: IaaS (Infrastructure), PaaS (Platform), and SaaS (Software).
- It began in the 1950s and has evolved into a dynamic service model, allowing on-demand resource access.
