Cybercrime refers to any criminal activity involving computers, networks, programs, data, and internet-enabled devices. As per reports, cybercrime may cost the global economy over $10 trillion between 2019-2023, up from $3 trillion between 2015-2019. This exponential rise highlights why individuals and organizations need to amp up cybersecurity measures.
In this comprehensive guide, we will provide an in-depth overview of different types of cyber threats, latest trends, tools leveraged, and notable real-world examples.
Alarming Cybercrime Statistics and Trends
Recent reports by leading cybersecurity firms highlight the relentless growth:
- Global cybercrime costs are expected to grow by 15% per year over the next 5 years, reaching over $10 trillion in damages by 2025.
- Ransomware attacks have witnessed a 105% annual growth rate from 2020 to 2021.
- Business email compromise scams rose by 65% from 2019 to 2020 alone as per FBI IC3 report with over 19,000 complaints of losses exceeding $1.8 billion.
- Reports of corporate account takeover grew by 72% from 2020 to 2021 globally.
- Cryptojacking malware incidents increased by a massive 2,968% between 2017-2021 as per Atlas VPN study.
| Year | Total Records Breached | Total Cost of Damages |
|---|---|---|
| 2021 | 22 billion+ | $6 trillion+ |
| 2025 (Expected) | 90 billion+ | $10+ trillion |
Some top cybercrime trends through 2024 include:
- More supply chain attacks by targeting trusted third-party partnerships.
- Increase in voice phishing (vishing) and deepfake attacks.
- More instances of double extortion ransomware demanding additional payments.
- Exponential rise in API attacks to access cloud apps and infrastructure.
Categorizing Different Types of Cyber Threats
Cybercriminals employ a variety of techniques to target individuals, businesses, and organizations as highlighted below:
1. Malware Software
- Viruses infect legitimate files and software to replicate.
- Worms self-propagate through networks without a host.
- Trojan horses embed malicious logic in useful apps.
- Ransomware restricts access to data until a ransom is paid.
- Spyware secretly collects user data and activity logs.
2. Phishing Attacks
- Fake emails and messages posing as trustworthy sources.
- Spoofing attacks falsify identities and locations.
- Voice phishing (vishing) and SMS phishing (SMiShing).
3. Denial-of-Service (DoS) Attacks
- Flood websites and networks with traffic to disrupt availability.
- Leverage botnets and zombie armies for large-scale DDoS attacks.
4. SQL Injection Attacks
- Exploit vulnerabilities in web apps by inserting malicious SQL statements in entry fields.
- Get access or modify entire databases.
5. Brute Force Cyber Attacks
- Software tools guessing passwords through trial-and-error.
- Exploit login pages by trying all letter/number combinations.
6. Illegal Dark Web Marketplaces
- Buy/sell hacked data, tools, malware, and other illegal services.
- Risky anonymization empowers criminal activities.
Cybercriminal Tools and Techniques
Cybercriminals use the following tools and technologies:
Malware Tools
- Keyloggers, screen grabbers
- Network sniffers
- Remote access tools (RATs)
- PowerShell malware
Vulnerability Exploitation
- Penetration testing tools
- Fuzzing tools
- Exploit kits released on dark web
Forensic Tools
- EnCase, Autopsy, Magnet AXIOM
- Network miner, Wireshark
Web Application Hacking

- Injecting cryptojacking malware to secretly mine cryptocurrency
Most High-Profile Cyber Attacks of Recent Times
Below are some major cyber attacks from recent years:
1. Anthem Data Breach (2015) – 79 million personal records stolen from health insurance giant.
2. Marriott International Breach (2018) – 383 million guest records containing sensitive PII taken.
3. Uber Breach (2016) – 57 million user accounts including names, emails accessed by attackers.
4. Adobe Breach (2013) – 38 million user records including credit card info stolen in well-orchestrated attack.
5. Colonial Pipeline Ransomware (2021) – Largest U.S. pipeline taken down by DarkSide ransomware causing gasoline supply shortages.
6. WannaCry Global Ransomware Attack (2017) – Wide-reaching attack encrypted over 200,000 computers across 150 countries demanding ransom in bitcoin cryptocurrency.
7. Ashley Madison Breach (2015) – 32 million accounts leaked from popular married dating site leading to lawsuits and blackmail.
8. Yahoo Data Breaches (2013-2014) – 3+ billion accounts compromised in series of attacks over 3 years in the biggest breach ever.
9. Equifax Breach (2017) – 143 million consumers‘ personal information stolen from top credit reporting agency.
10. Target Data Breach (2013) – Credit/debit card details of 70 million Target shoppers stolen in the holiday season.
As attacks grow exponentially, individuals and organizations need to take preventative measures:
- Enable two-factor authentication (2FA).
- Install endpoint detection tools.
- Patch and update software regularly.
- Conduct frequent backups.
- Establish incident response plans.
- Educate employees on security best practices.
With worldwide damages from cybercrime expected to hit $10 trillion by 2025, governments also need to strengthen cybersecurity laws and enable better threat information sharing between CERT teams, law enforcement, banks and financial institutions.
