Analysis Of Botnet Creation And Ddos Attack Offences
1. Understanding Botnet Creation & DDoS Offences
A. Botnet Creation
A botnet is a network of compromised computers controlled remotely by an attacker (“botmaster”).
Common offences related to botnet creation include:
Key Criminal Elements
Unauthorized access to a computer system
Installation of malware (Trojan, worm, rootkit)
Control of infected machines without consent
Use of the botnet for further crimes (spam, DDoS, credential theft)
Typical Laws Violated
US: Computer Fraud and Abuse Act (CFAA)
UK: Computer Misuse Act 1990 (CMA)
EU: Directive 2013/40/EU on attacks against information systems
International: Budapest Convention on Cybercrime
B. DDoS (Distributed Denial-of-Service) Attacks
A DDoS attack is when multiple systems flood a target (website, server, network) with traffic, disrupting availability.
Key Criminal Elements
Intentional interference with system functionality
Causing damage, loss, or service disruption
Use of multiple systems or a botnet
Legally Recognised Harms
Economic loss (downtime)
Disruption of critical services
Harassment or coercion
Extortion (DDoS-for-hire)
2. Major Case Law on Botnets & DDoS Attacks (Detailed)
Below are six significant and illustrative cases.
CASE 1: United States v. Jeanson James Ancheta (Botnet-for-hire case)
Facts
Ancheta operated a botnet consisting of hundreds of thousands of infected machines.
He used malware (“rxbot”) to compromise computers and then rented access to the botnet to spammers and advertisers.
He targeted military computers and commercial networks.
Legal Issues
Unauthorized access (CFAA)
Conspiracy and fraud
Damage to protected computers (military systems count as “protected”)
Outcome
He pled guilty in 2006.
Sentenced to 57 months, the first US case where someone was jailed solely for botnet activity.
Importance
Established that botnet rental = criminal enterprise.
Confirmed that infecting systems even without data theft is a serious offence.
CASE 2: United States v. Albert Gonzalez (Shadowcrew Botnet)
Facts
Gonzalez ran a botnet used to steal over 40 million credit and debit card numbers.
Used SQL injection + botnet to infiltrate corporate networks (TJX, Heartland Payment Systems).
Legal Issues
Conspiracy to commit computer fraud and wire fraud
Unauthorized access
Large-scale data theft via botnet operations
Outcome
Sentenced to 20 years, one of the longest cybercrime sentences in U.S. history.
Importance
Showed how botnets can be used not just for DDoS, but also credential harvesting.
Demonstrated severe sentencing when botnets are linked to financial harm.
CASE 3: R v. Lennon (UK, Computer Misuse Act – Email “mail-bombing” attack)
Facts
Lennon conducted a DDoS-like attack using massive volumes of emails against his former employer.
Intention: slow down or crash their mail servers.
Legal Issues
Whether sending large volumes of messages counts as “unauthorized modification” under UK CMA s.3.
Outcome
Court held that even if an email server receives email normally, excessive traffic intended to disrupt is illegal.
Lennon was convicted.
Importance
Landmark UK case confirming DDoS = unauthorized impairment of system functionality.
Clarified that you do not need to “hack” to commit a cyber offence.
CASE 4: Operation Power Off (vDOS / DDoS-for-Hire Service)
Facts
vDOS was the world’s largest booter/stresser (commercial DDoS‑for‑hire).
Responsible for over 150,000 DDoS attacks between 2014–2016.
Run by two Israeli teenagers.
Legal Issues
Offering services enabling others to commit DDoS attacks
Conspiracy and facilitating cybercrime
Money laundering through subscription payments
Outcome
Operators arrested; the service taken down.
Both received jail sentences and fines.
Importance
Crucial international case affirming that providing tools for DDoS is itself a criminal offence.
Reinforced law enforcement cooperation against cyber‑crime-as-a-service.
CASE 5: United States v. Paras Jha, Josiah White & Dalton Norman (Mirai Botnet)
Facts
Defendants created the Mirai botnet, compromising hundreds of thousands of IoT devices.
Used Mirai to attack large DNS provider Dyn, causing widespread internet outages (Twitter, Spotify, GitHub).
Legal Issues
Unauthorized access to IoT devices
Distribution of malware
Botnet exploitation
DDoS attacks affecting critical infrastructure
Outcome
They pled guilty (2017).
Sentences included house arrest, fines, and cooperation with the FBI.
Importance
Mirai became one of the most notorious botnets ever.
First major case addressing IoT vulnerabilities at scale.
Demonstrated that even “script-kiddie level” actors can cause global disruption.
CASE 6: United States v. Sergey Vovnenko (Botnet + credential theft)
Facts
Vovnenko ran a botnet used to steal login credentials and financial data from victims.
Operated criminal forums under aliases
Infected thousands of machines using malware and keyloggers.
Legal Issues
Identity theft
Unauthorized access
Botnet distribution and administration
Conspiracy to violate CFAA
Outcome
Extradited to the US and sentenced to 41 months.
Importance
Demonstrates that botnet creators can be extradited across borders.
Shows recognition of botnet‑driven identity theft as a serious offence.
3. Key Legal Principles Across Cases
1. Intent to disrupt or access is critical
Even if no data is stolen, the mere act of causing service disruption (DDoS) is criminal.
2. “Botnet-for-hire” = criminal facilitation
Running a booter/stresser service is treated the same as committing direct attacks.
3. Unauthorized access includes IoT devices
Mirai showed that even “simple” devices like cameras constitute protected systems.
4. Volume-based attacks are treated as unauthorized impairment
As established in R v. Lennon.
5. International cooperation is crucial
Most botnet cases involve extradition and joint law enforcement operations.
