Common Cybersecurity Threats

Phishing Attacks

High Risk

Phishing involves fraudulent communications (emails, messages, or calls) designed to trick users into revealing sensitive information or installing malware. Attackers impersonate trusted organizations to build credibility.

Real-World Case: Google & Facebook $100M Scam (2013-2015)

Lithuanian fraudster Evaldas Rimasauskas impersonated Quanta Computer, a legitimate hardware supplier, and sent fake invoices to Google and Facebook. Over two years, he successfully stole over $100 million before being caught. Both companies recovered most funds, but the incident highlighted how even tech giants can fall victim to sophisticated business email compromise (BEC) attacks.

Prevention Tips:

  • Verify email sender addresses carefully
  • Hover over links before clicking
  • Never share passwords via email
  • Use multi-factor authentication
  • Report suspicious emails to IT

Malware & Ransomware

Critical

Malware is malicious software designed to damage, disable, or exploit your systems. Ransomware specifically encrypts your data and demands payment for decryption. Both can spread through downloads, emails, or compromised websites.

Real-World Case: Colonial Pipeline Ransomware (May 2021)

DarkSide ransomware gang encrypted Colonial Pipeline's systems, forcing the shutdown of the largest fuel pipeline in the US, supplying 45% of the East Coast's fuel. The attack caused widespread panic buying and fuel shortages. Colonial paid $4.4 million in Bitcoin (later partially recovered by FBI). The incident demonstrated how ransomware can impact critical infrastructure and national security, leading to new cybersecurity regulations for critical sectors.

Prevention Tips:

  • Install reputable antivirus software
  • Keep systems and software updated
  • Avoid downloading from untrusted sources
  • Regular backups prevent data loss
  • Use endpoint protection tools

SQL Injection (SQLi)

High Risk

SQL Injection occurs when attackers insert malicious SQL commands into input fields. This can allow unauthorized database access, data theft, or modification. It targets web applications with poor input validation.

Real-World Case: Heartland Payment Systems (2008)

Heartland Payment Systems, a major payment processor, was breached via SQL injection attacks that compromised 130 million credit and debit card numbers. Attackers used SQLi to install malware that captured card data in real-time. The breach cost Heartland over $140 million in settlements and led to the company filing for bankruptcy protection. This incident was one of the largest data breaches in history and prompted stricter PCI-DSS compliance enforcement.

Prevention Tips:

  • Use parameterized queries/prepared statements
  • Validate all user inputs
  • Apply principle of least privilege
  • Use Web Application Firewalls (WAF)
  • Regular security testing and code review

Cross-Site Scripting (XSS)

Medium Risk

XSS attacks inject malicious scripts into web pages viewed by users. These scripts can steal cookies, sessions, or perform actions on behalf of the user. Common in poorly sanitized web applications.

Prevention Tips:

  • Sanitize all user inputs
  • Use Content Security Policy (CSP)
  • Encode output data properly
  • Use templating engines with auto-escaping
  • Regular security audits

Cross-Site Request Forgery (CSRF)

Medium Risk

CSRF attacks trick users into performing unwanted actions on websites where they're authenticated. Attackers exploit the trust between a website and the user's browser to execute unauthorized transactions.

Prevention Tips:

  • Implement CSRF tokens
  • Use SameSite cookie attributes
  • Verify HTTP referrer headers
  • Require re-authentication for sensitive actions
  • Educate users about suspicious links

Distributed Denial of Service (DDoS)

High Risk

DDoS attacks flood systems with traffic from multiple sources, making services unavailable. Attackers compromise many devices (botnets) to overwhelm targets. Impact ranges from service disruption to financial losses.

Real-World Case: GitHub DDoS Attack (February 2018)

GitHub experienced the largest DDoS attack ever recorded at the time, peaking at 1.35 Tbps (terabits per second). The attack leveraged memcached amplification, where attackers spoofed GitHub's IP and sent requests to thousands of memcached servers, which responded with amplified traffic. GitHub's DDoS mitigation service blocked the attack within 10 minutes, but the incident highlighted the vulnerability of exposed memcached servers and the scale of modern DDoS attacks.

Prevention Tips:

  • Use DDoS mitigation services
  • Implement rate limiting
  • Maintain redundant infrastructure
  • Have incident response plans
  • Monitor traffic patterns

Social Engineering

High Risk

Social engineering exploits human psychology rather than technical vulnerabilities. Attackers manipulate people into divulging secrets, bypassing security protocols, or granting access to systems through deception.

Prevention Tips:

  • Never share passwords or credentials
  • Verify identity before sharing info
  • Be skeptical of urgent requests
  • Report suspicious behavior
  • Regular security awareness training

Zero-Day Vulnerabilities

Critical

Zero-day exploits target unknown vulnerabilities in software that developers haven't patched yet. Attackers have an advantage because no fixes exist. Discovered vulnerabilities must be reported responsibly.

Real-World Case: Stuxnet Worm (2010)

Stuxnet was a sophisticated malware that exploited four zero-day vulnerabilities in Windows to target Iranian nuclear facilities. Believed to be developed by US and Israeli intelligence, it specifically targeted Siemens industrial control systems, causing centrifuges to malfunction while reporting normal operation. Stuxnet marked the first known cyber weapon to cause physical destruction and demonstrated the power of zero-day exploits in state-sponsored cyber warfare. The attack set Iran's nuclear program back by years.

Prevention Tips:

  • Apply security patches promptly
  • Use layered security (defense in depth)
  • Monitor for suspicious behavior
  • Participate in bug bounty programs
  • Follow responsible disclosure practices

2026 Emerging Threats

Stay ahead of the curve with knowledge of the latest and most sophisticated threats emerging in the cybersecurity landscape.

AI/Agentic Attacks

Critical - Emerging

AI-powered attacks use autonomous malware and machine learning to adapt defenses in real-time. Agentic AI systems can conduct reconnaissance, exploit vulnerabilities, and evade detection without human intervention. Prompt injection attacks target AI systems to manipulate outputs or leak sensitive data.

Prevention Tips:

  • Implement AI-aware security monitoring
  • Use prompt injection filters for AI systems
  • Sandbox AI model inference environments
  • Monitor for AI-driven behavioral anomalies
  • Establish AI governance and ethics policies

Deepfakes & Synthetic Media

High Risk

Deepfake technology creates convincing fake videos, audio, and images to impersonate executives, manipulate public opinion, or enhance social engineering attacks. Advanced phishing campaigns now use AI-generated voices and video in real-time to bypass authentication and deceive targets.

Prevention Tips:

  • Use deepfake detection tools and services
  • Implement multi-factor authentication beyond biometrics
  • Establish code words for sensitive communications
  • Train employees to recognize synthetic media
  • Verify identities through multiple channels

Quantum Computing Threats

Critical - Future

Quantum computers threaten to break current encryption standards (RSA, ECC) that protect financial transactions, secure communications, and data storage. "Harvest now, decrypt later" attacks collect encrypted data today to decrypt when quantum computers become powerful enough.

Prevention Tips:

  • Begin post-quantum cryptography (PQC) migration
  • Implement crypto-agility in systems
  • Use NIST-approved PQC algorithms
  • Assess quantum risk to sensitive data
  • Plan for hybrid classical-quantum encryption

Identity-led Attacks

Critical

Modern attacks increasingly target identities rather than infrastructure. Attackers steal credentials, abuse cloud permissions, and exploit identity systems to move laterally. Credential stuffing, password spraying, and privilege escalation bypass traditional perimeter defenses.

Prevention Tips:

  • Implement Zero Trust identity verification
  • Use passwordless authentication (FIDO2, WebAuthn)
  • Deploy identity threat detection and response (ITDR)
  • Enforce least privilege access everywhere
  • Monitor for anomalous authentication patterns

Advanced Ransomware (RansomOps)

Critical

Modern ransomware employs triple extortion: encrypting data, stealing sensitive files, and threatening DDoS attacks. Ransomware-as-a-Service (RaaS) platforms enable low-skill attackers. Advanced variants target backups, disable security tools, and use living-off-the-land techniques to evade detection.

Prevention Tips:

  • Maintain immutable, offline backups
  • Deploy endpoint detection and response (EDR)
  • Implement network segmentation and microsegmentation
  • Use application whitelisting and behavioral monitoring
  • Conduct regular ransomware tabletop exercises

Supply Chain Attacks

High Risk

Attackers compromise software supply chains, dependencies, and third-party services to reach thousands of downstream targets. Recent attacks targeted build systems, code repositories, and trusted software updates to distribute malware at scale.

Prevention Tips:

  • Implement Software Bill of Materials (SBOM)
  • Use code signing and verification
  • Monitor third-party vendor security posture
  • Isolate build and CI/CD environments
  • Conduct vendor security assessments
