Survey Note: Detailed Analysis of Historical DNS Hijacking Incidents
DNS hijacking, a cyberattack where attackers manipulate Domain Name System (DNS) queries to redirect users to malicious websites, has been a significant threat to internet security. This report provides a comprehensive analysis of historical security incidents caused by DNS hijacking, focusing on notable events that have impacted major organizations. The analysis is based on extensive research into security reports, news articles, and technical analyses, ensuring a thorough understanding of each incident’s scope and impact.
Understanding DNS Hijacking
DNS hijacking involves altering DNS queries, either by compromising a user’s device, router, or DNS server, to redirect traffic to attacker-controlled sites. This can be used for phishing, pharming, or espionage, exploiting the trust users place in the DNS to resolve legitimate domain names. The attack can occur through malware, router vulnerabilities, or intercepting DNS communications, making it a versatile and dangerous threat.
Methodology
The research began by defining DNS hijacking and distinguishing it from related attacks like DNS spoofing or poisoning. A web search was conducted for “historical DNS hijacking incidents” to identify specific events, followed by targeted searches for notable cases mentioned in initial results. Each incident was verified for accuracy, ensuring it involved DNS hijacking and not other cyberattack methods. The analysis includes detailed descriptions, dates, and impacts, with citations from reliable sources.
Detailed Incident Analysis
1. The 2018-2019 DNSp Espionage Campaign
This campaign, identified in late 2018 and early 2019, was a widespread DNS hijacking effort targeting government and private sector entities, particularly in the Middle East and Europe. The attackers, suspected to be state-sponsored, compromised DNS records to redirect traffic, enabling man-in-the-middle attacks and the interception of email and VPN traffic. Specific targets included:
- Iraqi National Security Agency (nsa.gov.iq)
- UAE Ministry of Foreign Affairs (webmail.mofa.gov.ae)
- Albania State Intelligence Service (shish.gov.al)
- Egypt Ministry of Foreign Affairs (mail.mfa.gov.eg)
- Egypt Ministry of Defense (mod.gov.eg)
- Libya Embassy (embassy.ly)
- Albania e-government portal (owa.e-albania.al)
- Kuwait Civil Aviation Bureau (mail.dgca.gov.kw)
- Jordan General Intelligence Directorate (gid.gov.jo)
- Abu Dhabi Police VPN (adpvpn.adpolice.gov.ae)
- Albanian State Police (mail.asp.gov.al)
- Cyprus Government Outlook Web Access (owa.gov.cy)
- Lebanon Ministry of Finance (webmail.finance.gov.lb)
- Egypt Ministry of Petroleum (mail.petroleum.gov.eg)
- Cyta, Cyprus telecommunications (mail.cyta.com.cy)
- Middle East Airlines email (mail.mea.com.lb)
The campaign involved compromising registrar accounts, with attacks lasting from hours to days, and attackers obtaining SSL certificates to enhance the legitimacy of fake sites. This incident highlighted the global scale of DNS hijacking, affecting over 50 entities and underscoring the need for robust DNS security.

2. The 2013 New York Times Incident
On August 27, 2013, the Syrian Electronic Army (SEA) conducted a DNS hijacking attack on The New York Times, compromising the domain registrar Melbourne IT through phishing. This allowed them to alter DNS records, redirecting users to a rogue site displaying SEA messages. The attack disrupted access to the legitimate website, potentially exposing users to phishing attempts. It was part of SEA’s broader campaign against Western media, reflecting political motivations.

3. The 2016 Brazilian Bank Incident
On October 22, 2016, hackers executed a sophisticated DNS hijacking attack on a major Brazilian bank, compromising its account at Registro.br, the Brazilian domain registrar. They altered DNS records for all 36 bank domains, redirecting traffic to attacker-controlled servers on Google’s Cloud Platform. This enabled phishing sites with valid HTTPS certificates, stealing customer credentials and infecting devices with malware. The attack lasted about five hours, severely impacting the bank’s online operations and customer trust.

4. The 2009 X Incident
On December 17, 2009, the “Iranian Cyber Army” hijacked X’s DNS records, redirecting users to a defaced site for about an hour. The attack involved altering DNS entries, likely through compromising the registrar, and was used for hacktivism, displaying a message claiming responsibility. While API services remained unaffected, the incident highlighted the vulnerability of social media platforms to DNS hijacking, raising concerns about potential data exposure.

Additional Context and Observations
The research revealed that DNS hijacking often exploits registrar vulnerabilities, as seen in the New York Times and Brazilian bank incidents, rather than solely targeting user devices. This underscores the importance of securing domain management systems. The DNSp espionage campaign’s scale, affecting over 50 entities, was particularly notable, with specific targets listed in detailed reports. The 2009 X incident, while brief, was significant for its impact on a major social media platform, illustrating the potential for widespread disruption.
An unexpected finding was the use of SSL certificates in several attacks, such as the DNSp campaign and Brazilian bank heist, to enhance the legitimacy of fake sites, complicating detection for users. This highlights the evolving sophistication of DNS hijacking techniques.
Comparative Table of Incidents
| Incident | Date | Target | Method | Impact |
|---|---|---|---|---|
| DNSp Espionage Campaign | 2018-2019 | Gov’t & private entities | Compromised registrar, altered DNS | Intercepted emails, VPN traffic, over 50 targets |
| New York Times Attack | August 27, 2013 | The New York Times | Phishing registrar, DNS redirection | Website disruption, potential phishing exposure |
| Brazilian Bank Heist | October 22, 2016 | Major Brazilian bank | Hijacked registrar, redirected domains | Stolen credentials, malware infection, 5-hour outage |
| X Incident | December 17, 2009 | X (Twitter) | Altered DNS records | Site defacement, 1-hour disruption |
This table summarizes the key details, aiding in understanding the scope and impact of each incident.
Conclusion
The historical security incidents caused by DNS hijacking demonstrate its potential for significant disruption and harm, affecting critical infrastructure, media, and financial systems. The 2018-2019 DNSp espionage campaign, 2013 New York Times attack, 2016 Brazilian bank heist, and 2009 X incident are among the most notable, each highlighting different facets of the threat.
