币界网报道：The FBI has arrested a 22-year-old British national for allegedly hacking into multiple U.S. companies and stealing sensitive data affecting over 25 million users. The suspect, identified as Joseph James O'Connor, was extradited from Spain and faces charges including computer intrusion, wire fraud, and identity theft. Authorities claim O'Connor used sophisticated phishing techniques to compromise corporate networks, accessing customer databases containing personal information. The breaches reportedly impacted major tech firms and financial institutions, though specific companies weren't named in court documents. Prosecutors estimate the total damages exceed $25 million, including remediation costs and lost business. The arrest follows a two-year international investigation involving cybersecurity experts from private firms and multiple law enforcement agencies. O'Connor could face up to 77 years in prison if convicted on all counts. The case highlights growing concerns about transnational cybercrime and the vulnerability of corporate data systems to social engineering attacks.
