Bogdan Nicolescu, Tiberiu Danet, Radu Miclaus Indicted in $4M Cyber Fraud

Three Romanian nationals—Bogdan Nicolescu, 34, Tiberiu Danet, 31, and Radu Miclaus, 34—are facing a 21-count federal indictment for orchestrating a sprawling cyber fraud conspiracy that infected over 60,000 computers, unleashed 11 million malicious emails, and stole at least $4 million from American victims. The indictment, unsealed in the Northern District of Ohio, marks the culmination of a years-long transnational investigation into a sophisticated digital crime ring operated from Bucharest.

Extradited to the United States this week after being apprehended in Romania earlier in the year, the defendants stand charged with conspiracy to commit wire fraud, conspiracy to traffic in counterfeit service marks, aggravated identity theft, conspiracy to commit money laundering, and 12 counts each of wire fraud. Prosecutors say the scheme began in 2007 with the development of proprietary malware designed to infiltrate computers through deceptive emails that appeared to come from trusted entities like Western Union, Norton AntiVirus, and the IRS.

Once a victim clicked on an infected attachment, the malware silently installed itself, harvesting email addresses, login credentials, and financial data. The attackers used this stolen information to hijack accounts, register over 100,000 AOL email addresses, and blast millions of phishing emails to harvested contact lists. The operation leveraged infected machines not only for espionage but also for cryptocurrency mining, exploiting the processing power of victims’ computers for illicit profit.

Investigators allege the trio rerouted victims visiting sites like PayPal, eBay, and Facebook to nearly identical fake pages they hosted, capturing login details in real time. They also disabled antivirus software and blocked access to law enforcement websites to evade detection. The compromised computers—mostly located in the U.S.—formed a stealth botnet that amplified the reach and persistence of the fraud network.

“This case illustrates the sophistication and determination with which cyber criminals seek to harm Americans and American businesses from abroad,” said Assistant Attorney General Leslie R. Caldwell. “But our response demonstrates that, with effective international cooperation, we can track these criminals down and make sure they face justice, no matter where or how they try to hide.”

U.S. Attorney Carole S. Rendon and FBI Special Agent in Charge Stephen D. Anthony emphasized the growing threat of cybercrime and the necessity of public-private partnerships in combating it. “These defendants stole millions of dollars from people in the United States through a sophisticated fraud conspiracy they operated in Eastern Europe,” Rendon said. “Despite the complexity and global character of these investigations, these arrests demonstrate the commitment by the FBI and our partners to aggressively pursue these individuals and bring justice to the victims.”
