Top 10 Most Dangerous Hackers In The World

In History an increasingly digital world, hackers represent a formidable force with the potential to disrupt economies, invade privacy, and challenge national security. From breaching government systems to leaking sensitive personal data, the actions of these individuals can have far-reaching consequences. Below is a look at ten of the most notorious hackers whose exploits have made headlines and raised alarms globally.

## 10. Jonathan James

Operating under the pseudonym "Comrade," Jonathan James made headlines in 1999 as a 15-year-old hacker. He was the first juvenile convicted of hacking in the U.S. After gaining unauthorized access to systems like BellSouth, the Miami-Dade school system, NASA, and the Department of Defense, James stole software valued at $1.7 million, causing NASA to shut down its systems for 21 days. Tragically, he faced intense scrutiny from the Secret Service in 2007 for a crime he didn’t commit, leading to his suicide in 2008.

## 9. Matthew Bevan and Richard Price

This British duo pulled off significant hacks in the 1990s, targeting U.S. military systems, including the Pentagon. They copied sensitive data from American military bases and even intercepted communications from U.S. agents in North Korea. Their hacking activities raised fears about potential acts of war but ultimately resulted in their arrest in 1995.

## 8. Edward Majerczyk

Known for orchestrating "Celebgate," Edward Majerczyk hacked into the iCloud accounts of numerous celebrities, including Jennifer Lawrence, between 2013 and 2014. Through phishing schemes, he obtained usernames and passwords, leaking sensitive photographs online. His actions led to a nine-month prison sentence after he pled guilty.

## 7. Gary McKinnon

Claiming to search for evidence of extraterrestrial life, Gary McKinnon hacked nearly 100 U.S. military and NASA servers between 2001 and 2002. His activities resulted in significant damage, costing the U.S. government over $700,000 to recover lost data. McKinnon famously taunted the military by declaring their security measures inadequate.

## 6. Guardians of Peace

In 2014, a hacker group known as the Guardians of Peace targeted Sony Pictures Entertainment, primarily due to the release of the film *The Interview*, which depicted the assassination of North Korean leader Kim Jong-un. The group leaked confidential documents and unreleased films, threatening violence if the movie was distributed. Their identity remains unknown.

## 5. Karl Koch

A member of the Chaos Computer Club in the 1980s, Karl Koch engaged in espionage activities during the Cold War. He hacked into several U.S. government agencies, selling sensitive information to the KGB. Koch's suspicious death in 1989, ruled a suicide, has fueled speculation about potential foul play.

## 4. Kevin Mitnick

Once the most wanted cybercriminal in the U.S., Kevin Mitnick was arrested in 1995 after a long cat-and-mouse game with law enforcement. Mitnick hacked into major corporations, including Nokia and IBM, but claimed his actions were driven by curiosity rather than malice. After serving time in prison, he transformed into a white-hat hacker and security consultant, emphasizing the importance of cybersecurity.

## 3. Albert Gonzalez

Gonzalez was involved in one of the largest credit card thefts in history. He hacked into several major retailers and stole over 180 million credit card accounts, using SQL injection techniques. His hacking operation, known as “Operation Get Rich or Die Trying,” netted him millions before he was caught and sentenced to 20 years in prison.

## 2. Kale Gamble

At just 15 years old, Kale Gamble became a prominent member of the hacking group "Crackas With Attitude" (CWA). He hacked into the personal accounts of high-profile government officials, including CIA Director John Brennan. Gamble was arrested in 2016 and sentenced to two years in prison, during which he was barred from using the internet. He has since aimed to establish a career in cybersecurity.

## 1. Astra

Astra, an unidentified Greek hacker, managed to infiltrate the Dassault Group for nearly five years, stealing advanced military technology. His hacks reportedly cost the company $360 million. Despite his significant impact and subsequent arrest, his true identity remains a mystery, underscoring the elusive nature of some of the most dangerous hackers.
