• Cryptomining – Using infected systems resources to mine cryptocurrency by installing cryptominers.
• Command and control – Allowing remote control of systems to orchestrate further attacks on networks.
• Propagation – Self-replicating across networks to infect more systems after initial infiltration.

Wadware’s system impacts enable attackers to pursue many illegal or unethical goals. Understanding the scope of potential damage is key for prevention.

Case Studies of Wadware Attacks

Looking at real-world examples of wadware attacks further highlights the consequences:

• The WannaCry ransomware outbreak in 2017 infected over 200,000 systems across 150 countries by exploiting a Windows vulnerability. It caused billions in damage before being stopped.
• The notorious Zeus banking trojan has been active since 2006 stealing hundreds of millions by covertly recording banking credentials with keystroke logging and screen capturing.
• The Storm worm botnet at its peak controlled an estimated 1-10 million computers sending massive amounts of spam emails, spreading wadware, and launching DDoS attacks.
• The Stuxnet worm, thought to be government-created, damaged Iran’s nuclear program by sabotaging industrial control systems in uranium enrichment facilities.
• The 2014 POS RAM scraper attacks installed wadware on retailers’ point-of-sale systems to steal the credit card details of 56 million customers.

These examples exhibit the wide-ranging damage wadware can inflict when compromising systems, from financial theft to critical infrastructure disruption. Understanding past attacks provides perspective on future threats.

The Risks and Consequences of Wadware

Given wadware’s immense threat potential, as demonstrated above, understanding the primary categories of risk wadware introduces is imperative for properly assessing its dangers. Major consequences include financial damages, data/privacy compromise, and legal/regulatory impacts.

Financial Implications

Wadware poses major financial risks in multiple forms:

• Ransoms – Extortion payments directly to attackers to recover encrypted data or systems. Recent ransomware attacks have averaged over $170,000 per incident.
• Remediation costs – Expenses for forensic analysis, network monitoring, system repairs/replacement, IT support, and new security measures after an attack. These average $1.1 million per enterprise wadware attack.
• Lost productivity – Businesses losing work hours and operational capacity during wadware attacks and subsequent recovery time, averaging $67,000 per hour.
• Fines/liabilities – Regulatory and contractual penalties for compromised customer data.
• Stolen funds – Direct theft through payment fraud or stealing financial account/credential information.

Wadware’s financial toll can be severe for both individual users and enterprises. Knowing these monetary risks informs prudent precautionary investments.

Data Breaches and Privacy Concerns

Beyond direct financial impacts, wadware also introduces troubling data security and privacy risks:

• Credential theft – Wadware covertly capturing login credentials for financial systems, email, social media, and other sensitive accounts.
• IP theft – Stealing proprietary data like trade secrets, source code, and confidential business data that can undermine an enterprise’s competitive positioning.
• Identity theft – Collecting personal identifiable information to impersonate individuals and commit fraud in their names.
• Privacy invasions – Spyware wadware secretly recording users through device cameras and microphones without consent.
• Records exposure – Breaches exposing sensitive customer data like healthcare records, social security numbers, home addresses, and full names.
• Regulatory non-compliance – Violating data protection regulations like HIPAA healthcare laws or GDPR by failing to secure information adequately.

These risks highlight wadware’s power to not just disrupt day-to-day operations but also compromise sensitive data at scale for serious privacy and compliance consequences.
