Attacks are classified into web-based and system-based categories.

Web-Based Attacks

Injection attacks manipulate web applications through data injection (e.g., SQL Injection).
DNS spoofing alters DNS resolver caches, redirecting traffic to fraudulent IP addresses.
Session hijacking compromises user sessions by stealing authentication cookies.
Phishing schemes deceive victims into providing sensitive information.
Brute force attacks use trial-and-error methods to crack passwords.
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 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.

Reporting Cyberstalking

Document evidence of harassment through screenshots and communication records.
Block and report offenders on social media platforms.
Contact local law enforcement and relevant cybercrime agencies to file complaints.
Seek legal advice for potential legal actions and ramifications.

Cyberstalking Laws in India

Identity theft is prohibited under Section 66C of the Information Technology Act.
Publishing obscene material is illegal as per Section 67 of the Information Technology Act.
Stalking is addressed by Section 354D of the Indian Penal Code.
Insulting modesty and making threats online are covered under specific IPC sections.

Cyber Cafés and Cyber Crime

Cyber cafés provide public access to the internet and related services for a fee, facilitating various online activities.### Cyber Crimes in Cyber Cafés
Cyber cafés facilitate internet access but are vulnerable to cybercrime due to their public nature.
Identity theft can occur through key loggers or malicious software, capturing personal data like login credentials.
Hackers exploit network vulnerabilities to gain unauthorized access to users' accounts and café systems.
Phishing attacks often occur in cyber cafés through fraudulent emails or websites aimed at stealing personal information.
Public computers can be used to download and spread malware, which can then steal data or create botnets.
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.

Benefits and Risks of Cloud Computing

Key benefits include platform-independent access, no software installation needed, cost-effectiveness, and reliable resource utilization.
Major risks include security and privacy concerns, vendor lock-in, isolation failures, management interface compromises, and potential data deletion issues.
