Hacking has been around since the early days of computers and networks. From pranks by mischievous students to cyber espionage by nation states, hackers have breached systems and caused chaos for decades. Some hacks have stood out as particularly audacious or impactful. But what is the most famous hack in history? There are a few contenders for this title.
Candidates for Most Famous Hack
Morris Worm – 1988
The Morris worm was one of the first widely known computer worms. It was created in 1988 by Cornell graduate student Robert Morris. The worm was designed to gauge the size of the internet, but it spread much faster than anticipated due to a coding error. It infected thousands of university, government, and private computers running Unix. The Morris worm knocked approximately 10% of computers on the early internet offline as administrators worked to contain and eradicate it. The worm highlighted the vulnerability of networks to malicious code. Robert Morris became the first person convicted under the Computer Fraud and Abuse Act and his case helped shape cybercrime policy. However, the long term impacts of the Morris worm were limited.
Solar Sunrise – 1998
Solar Sunrise was the name given to series of intrusions into U.S. military networks that occurred in February 1998. The attacks exploited known vulnerabilities in Solaris systems to install backdoors and sniffers to monitor traffic on compromised networks. The scale of the intrusions and targeting of defense systems raised concerns about potential cyber warfare. The U.S. launched an intensive investigation in collaboration with the FBI and Israeli government. The culprits turned out to be two teenage hackers in California and one in Israel who were looking to test their skills and never intended real damage. Though the three were identified and sentenced, the ease with which they infiltrated military networks was an embarrassing episode that highlighted vulnerabilities.
ILOVEYOU Virus – 2000
The ILOVEYOU virus, also known as the Love Bug or Love Letter, was a computer worm that infected millions of Windows PCs worldwide in May 2000. The malicious code was distributed via an email with the subject “ILOVEYOU” and an attachment “LOVE-LETTER-FOR-YOU.txt.vbs”. When users opened the attachment it overwrote files and sent copies to email contacts. The simplicity of the attack allowed the virus to spread rapidly across the globe in hours. It is estimated that the Love Bug caused $5-10 billion in damages making it among the most costly malware incidents in history. The outbreak forced many organizations to improve security measures and make workers more aware of cyber threats. The creator, a student in the Philippines, was identified but never charged.
Sony Pictures Hack – 2014
In November 2014, hackers breached the network of Sony Pictures and unleashed one of the most devastating cyber attacks against a company to date. The attackers unleashed malware that wiped hard drives, stole confidential data, and leaked upcoming movies. Terabytes of sensitive internal information including executive emails were released online. A hacker group called the Guardians of Peace took credit, demanding that Sony cancel its satirical film depicting the assassination of North Korean leader Kim Jong-Un. U.S officials ultimately attributed the attack to North Korea. The Sony hack showed that nation-state actors could cripple a major international company through cyber attacks. The events were a wake up call that prompted businesses to focus more resources on cybersecurity.
Stuxnet – Most Famous Hack in History
While all of the aforementioned hacks were highly notable, none match the sophistication and impact of Stuxnet. Stuxnet was a computer worm discovered in 2010 that targeted industrial control systems. It is believed to have been developed jointly by U.S. and Israeli intelligence agencies as part of a covert operation against Iran’s nuclear program. The worm was designed to spread via infected USB drives and subvert the programmable logic controllers (PLCs) used in centrifuges for uranium enrichment.
How Stuxnet Worked
Stuxnet took advantage of multiple zero-day vulnerabilities to infiltrate systems and establish remote control over PLCs. Specifically it targeted Siemens STEP 7 software which was used to program industrial control systems in Iranian facilities. Stuxnet contained legitimate code certificates to disguise itself as valid software. The worm reprogrammed PLCs to operate as normal most of the time, but periodically increase centrifuges’ rotor speeds which caused them to suffer damage over time. Meanwhile it sent false feedback signals to plant operators showing systems operating normally. This allowed the centrifuges to be slowly destroyed while the virus hid itself and its impacts from monitoring systems.
Damage to Iranian Nuclear Facilities
It is estimated that Stuxnet damaged almost 20% of Iran’s nuclear centrifuges, setting back its weapons program substantially. When the worm propagated to outside systems, the unusual code raised suspicion from cybersecurity researchers. Though its original target was not known at the time, it was dubbed “Stuxnet” based on code file names. Iran has since managed to recover its uranium production capabilities. However, Stuxnet opened eyes about the potential for cyber attacks to cause physical damage to critical infrastructure.
First Weaponized Malware
Stuxnet has been hailed as the first true cyber “superweapon” and first-known example of “weaponized” malware. It represented the most sophisticated computer worm created to that point. Stuxnet gave the U.S. and Israel the capability to covertly and subtly sabotage Iranian nuclear facilities in a way no military operation could have achieved. The degree of technical expertise required was beyond the capabilities of independent hackers. Stuxnet’s design required extensive intelligence about Iran’s nuclear program and industrial control systems. Based on its stealthy and targeted nature, it is now considered the first cyberweapon used for counter-proliferation objectives.
Reasons Stuxnet Was the Most Famous Hack
Stuxnet stands out as the most famous hack in history largely because it:
- Inflicted substantial physical damage to critical infrastructure in a foreign country via cyber attack for the first time.
- Was an incredibly sophisticated worm that illustrated the extent of resources behind nation-state cyber operations.
- Initially spread in obscurity but was ultimately discovered and analyzed by security researchers.
- Signaled that cyber warfare had essentially arrived and showed the world what covert operations in cyberspace could accomplish.
It set precedents that had never been seen before or since in terms of technical achievement, real-world impact, and strategic objectives. Stuxnet opened up new possibilities for computer-enabled warfare. It remains the crown jewel of cyber weapons, demonstrating that malware could now do a lot more than steal data or money. Similar state-sponsored malware has since been uncovered but none are considered as advanced as Stuxnet. Its design philosophy has inspired state-sponsored hackers to develop more stealthy and surgical weapons. In many ways, Stuxnet set the bar for the future evolution of cyber weapons.
Impact on Cybersecurity & Policy
Stuxnet served as a wake up call to governments, businesses, and security professionals about this new breed of malware. It showed that critical infrastructure like power grids, transportation systems, dams, and manufacturing plants were vulnerable to digital attacks. Stuxnet revealed that cybersecurity was now a high-stakes game between sophisticated state adversaries vying for strategic advantage. In a world where technology was growing more connected and embedded into physical systems, an entity’s cyber defense capabilities had become crucial to national security. Industrial control systems once considered secure were exposed as antiquated and full of holes. The worm was a stark demonstration that cyber attacks were no longer limited to stealing information – they could be used to directly sabotage physical systems and processes.
Industrial Control System Security Heightened
In response to Stuxnet, government agencies and companies overseeing critical infrastructure devoted more focus to auditing and securing industrial control systems. New standards like ISA 99 were adopted to improve cybersecurity readiness for industrial automation and SCADA systems. Simultaneously, ICS vendors put more effort into patching vulnerabilities. Operators instituted more robust cybersecurity controls, network segmentation, and monitoring to make ICS environments more resilient. These changes have made many critical infrastructure facilities much harder to infiltrate. While work remains, Stuxnet was a turning point that instigated big improvements in control system security.
Acceleration of Cyberwarfare Programs by Nation States
Intelligence agencies and militaries around the world stepped up development of cyber warfare capabilities after Stuxnet was uncovered. The lessons from Stuxnet were analyzed and adopted by other countries to create advanced cyber weapons of their own. It essentially signaled that cyber attacks were fair game for covert action against foreign adversaries. State-sponsored hacking groups became much more active following Stuxnet. At the same time, governments expanded cyber defense units to harden critical networks and vital secrets against enemy intrusions. Cyber command structures were created with offense and defense mandates. Cyber warfare development accelerated as an area of strategic competition between great powers.
Growth of the Cybersecurity Industry
Stuxnet led to booming growth in the cybersecurity industry including security firms, consultants, and researchers specializing in industrial control system protection. Awareness of cyber threats to critical infrastructure created new demand from both the public and private sectors. Governments expanded spending on cybersecurity technology to defend IT systems, weapons platforms, utilities, and more. Private companies rushed to harden defenses and compliance requirements expanded. The industry mushroomed over the decade after Stuxnet as cybersecurity became big business. The surging job market could not keep up with demand for cybersecurity professionals. Stuxnet powered the rise of cybersecurity into a dominant industry.
