  • Joseph O’Connor, known as the “Twitter hacker,” has been sentenced for his involvement in a Twitter hack and a SIM swapping scheme targeting high-profile cryptocurrency industry executives.
  • O’Connor hijacked prominent Twitter accounts, including CoinDesk, to carry out a bitcoin giveaway scam, amassing over $100,000.

In a significant development of the cryptocurrency industry, Joseph O’Connor, a British man widely known as the “Twitter hacker,” has been sentenced to 5 years in prison by a federal judge in the U.S. District Court for the Southern District of New York. O’Connor was responsible for orchestrating an elaborate Twitter hack and a separate crypto-related SIM-swapping scheme, amassing approximately $900,000 from his victims. 

The sentencing comes after O’Connor’s guilty plea to engage in SIM-swapping attacks that targeted high-profile cryptocurrency industry executives, resulting in the theft of digital currencies valued at $794,000. The judge emphasized the impact of O’Connor’s actions on the lives of his victims, highlighting the need for accountability.

O’Connor’s Devastating Twitter Hack and Bitcoin Giveaway Scam

In 2020, Joseph O’Connor, known online as PlugWalkJoe, executed a highly sophisticated Twitter hack that had far-reaching consequences. By infiltrating prominent accounts on the platform, including CoinDesk, O’Connor seized control and utilized them to propagate a Bitcoin giveaway scam. The scheme enticed users into sending funds with the promise of multiplying their investments. Through this illicit activity, O’Connor managed to amass a staggering $103,960.

The Twitter hack sent shockwaves through the cryptocurrency community, as it exposed vulnerabilities within the platform and raised concerns about the security of high-profile accounts. This incident served as a wake-up call for Twitter and prompted the implementation of enhanced security measures to safeguard against future breaches.

SIM-Swapping Attacks Targeting Cryptocurrency Industry Executives

In addition to his Twitter hack, Joseph O’Connor orchestrated a series of SIM-swapping attacks, specifically targeting influential figures in the cryptocurrency industry. SIM swapping involves manipulating telecom providers to transfer a victim’s phone number to a device controlled by the hacker, granting them unauthorized access to personal accounts and sensitive information.

Through these targeted attacks, O’Connor successfully swindled approximately $794,000 worth of digital currencies from high-profile executives. The theft not only resulted in significant financial losses for the victims but also undermined trust and confidence in the security of the cryptocurrency industry as a whole.

Accountability Sought as O’Connor Receives Federal Sentencing

After evading authorities for a year, Joseph O’Connor was apprehended in Spain in 2021. Following his arrest, he has spent 28 months in custody, and with the recent sentencing, he is expected to serve an additional three years behind bars.

During the sentencing, Judge Jed Rakoff emphasized the impact of O’Connor’s actions on the lives of his victims. The judge stressed the importance of holding individuals accountable for their cybercrimes, particularly those involving financial theft and the exploitation of online platforms.

Judge Rakoff’s emphasis on accountability underscores the gravity of Joseph O’Connor’s cybercrimes. With his capture and sentencing, justice serves as a deterrent against future illicit activities, promoting the security and trustworthiness of online platforms.


Joseph O’Connor’s conviction and subsequent five-year prison sentence for his involvement in a Twitter hack and SIM-swapping scheme mark a significant step towards combating cybercrime and ensuring accountability in the digital age. O’Connor’s actions not only resulted in substantial financial losses for his victims but also exposed vulnerabilities within social media platforms and the cryptocurrency industry. As technology continues to advance, it is imperative that individuals engaging in illegal online activities are brought to justice to safeguard the integrity and security of online spaces.
