Distributed Denial-Of-Service Attack Prosecutions
What is a Distributed Denial-of-Service (DDoS) Attack?
A DDoS attack floods a targeted computer, server, or network with overwhelming traffic from multiple sources, causing the system to slow down or crash, denying service to legitimate users. It’s illegal under various cybercrime laws, and perpetrators are prosecuted for computer misuse, unauthorized access, or related offenses.
Detailed Case Explanations
1. United States v. Aaron Swartz
Facts:
Although not primarily for a DDoS, Aaron Swartz was involved in hacking and unauthorized access cases. In some cases related to his activism, websites he targeted experienced interruptions due to heavy traffic or scraping. His case raised awareness about the consequences of internet activism crossing legal boundaries.
Legal Issues:
Swartz was charged with wire fraud and violations of the Computer Fraud and Abuse Act (CFAA). The issue centered on unauthorized access and data downloading, but some similar cases involved DDoS tactics as well.
Outcome:
Swartz faced heavy prosecution pressure, and his tragic suicide sparked debate on prosecutorial overreach in cybercrime cases.
Significance:
Though not a DDoS case per se, it highlights legal risks of cyber activism and the harsh penalties under the CFAA.
2. United States v. Christopher Weatherhead (2015)
Facts:
Christopher Weatherhead, a member of the hacktivist group “Lizard Squad,” orchestrated DDoS attacks against gaming networks like PlayStation Network and Xbox Live, causing widespread service outages.
Legal Issues:
Charged with conspiracy to commit computer fraud and abuse. The prosecution needed to prove Weatherhead intentionally caused damage to protected computers through DDoS.
Outcome:
Weatherhead pleaded guilty and was sentenced to 2 years in prison.
Significance:
This case shows how DDoS attacks targeting commercial networks lead to criminal prosecutions and significant penalties.
3. United Kingdom v. Ryan Cleary (2013)
Facts:
Cleary, a member of the hacking group “LulzSec,” was involved in several DDoS attacks against government and private sector websites, disrupting services and causing reputational damage.
Legal Issues:
Charged with unauthorized access and launching DDoS attacks under the UK’s Computer Misuse Act. The court examined the extent of Cleary’s role and intent.
Outcome:
Cleary pleaded guilty and received a custodial sentence.
Significance:
Demonstrates UK’s approach to prosecuting DDoS attackers and the use of computer misuse laws to address cyber disruptions.
4. United States v. Weev (Andrew Auernheimer)
Facts:
Andrew Auernheimer, aka “Weev,” was convicted not for DDoS but related cybercrimes involving unauthorized access. However, his case is often referenced alongside DDoS prosecutions because of its cybercrime context.
Legal Issues:
Auernheimer was charged under the CFAA for hacking into AT&T servers and obtaining user data, raising questions about cybercrime statutes’ reach.
Outcome:
Convicted initially but later had his conviction overturned due to jurisdiction issues.
Significance:
Though not a DDoS case, it shows legal challenges in prosecuting cyber offenses, relevant to DDoS cases’ complexity.
5. United States v. Weimer and Carber (2016)
Facts:
Two defendants were prosecuted for operating “booter” or “stresser” services, which sold access to DDoS tools allowing customers to launch attacks on third parties.
Legal Issues:
Charged with conspiracy to commit fraud and unauthorized damage to computers. The government argued these services facilitated illegal DDoS attacks at scale.
Outcome:
Both pleaded guilty and received prison sentences.
Significance:
Highlights the prosecution of not just individual attackers but operators enabling DDoS as a service.
6. United States v. Mir Islam (2018)
Facts:
Mir Islam launched a DDoS attack on multiple financial institutions and government websites. He bragged about his actions on social media.
Legal Issues:
Charged with multiple counts of intentional damage to protected computers under the CFAA and related statutes.
Outcome:
Convicted and sentenced to several years in federal prison.
Significance:
This case emphasizes how boasting about attacks can lead to detection and prosecution.
Common Legal Themes in DDoS Prosecutions
Charges: Typically under the Computer Fraud and Abuse Act (CFAA) or equivalent cybercrime laws.
Intent: Prosecutors must prove that the defendant knowingly caused damage or disruption.
Scale: Some cases involve individual hackers; others target operators of DDoS-for-hire services.
Sentencing: Penalties range from probation to multi-year prison terms depending on severity and impact.
Evidence: Digital forensic evidence, communications, and sometimes admissions on social media.
