Last summer, a wave of sextortion emails began flooding inboxes around the world. The spammers behind this scheme claimed they’d hacked your computer and recorded videos of you watching porn, and promised to release the embarrassing footage to all your contacts unless a bitcoin demand was paid. Now, French authorities say they’ve charged two men they believe are responsible for masterminding this scam. One of them is a 21-year-old hacker interviewed by KrebsOnSecurity in 2017 who openly admitted to authoring a banking trojan called “Nuclear Bot.”
On Dec. 15, the French news daily Le Parisien published a report stating that French authorities had arrested and charged two men in the sextortion scheme. The story doesn’t name either individual, but rather refers to one of the accused only by the pseudonym “Antoine I.,” noting that his first had been changed (presumably to protect his identity because he hasn’t yet been convicted of a crime).
“According to sources close to the investigation, Antoine I. surrendered to the French authorities at the beginning of the month, after being hunted down all over Europe,” the story notes. “The young Frenchman, who lived between Ukraine, Poland and the Baltic countries, was indicted on 6 December for ‘extortion by organized gang, fraudulent access to a data processing system and money laundering.’ He was placed in pre-trial detention.”
According to Le Parisien, Antoine I. admitted to being the inventor of the initial 2018 sextortion scam, which was subsequently imitated by countless other ne’er-do-wells. The story says the two men deployed malware to compromise at least 2,000 computers that were used to blast out the sextortion emails.
While that story is light on details about the identities of the accused, an earlier version of it published Dec. 14 includes more helpful clues. The Dec. 14 piece said Antoine I. had been interviewed by KrebsOnSecurity in April 2017, where he boasted about having created Nuclear Bot, a malware strain designed to steal banking credentials from victims.
My April 2017 exposé featured an interview with Augustin Inzirillo, a young man who came across as deeply conflicted about his chosen career path. That path became traceable after he released the computer code for Nuclear Bot on GitHub. Inzirillo outed himself by defending the sophistication of his malware after it was ridiculed by both security researchers and denizens of the cybercrime underground, where copies of the code wound up for sale. From that story:
“It was a big mistake, because now I know people will reuse my code to steal money from other people,” Inzirillo told KrebsOnSecurity in an online chat.
Inzirillo released the code on GitHub with a short note explaining his motivations, and included a contact email address at a domain (inzirillo.com) set up long ago by his father, Daniel Inzirillo.
KrebsOnSecurity also reached out to Daniel, and heard back from him roughly an hour before Augustin replied to requests for an interview. Inzirillo the elder said his son used the family domain name in his source code release as part of a misguided attempt to impress him.
“He didn’t do it for money,” said Daniel Inzirillo, whose CV shows he has built an impressive career in computer programming and working for various financial institutions. “He did it to spite all the cyber shitheads. The idea was that they wouldn’t be able to sell his software anymore because it was now free for grabs.”
If Augustin Inzirillo ever did truly desire to change his ways, it wasn’t clear from his apparent actions last summer: The Le Parisien story says the sextortion scams netted the Frenchman and his co-conspirator at least a million Euros.
In August 2018, KrebsOnSecurity was contacted by a researcher working with French authorities on the investigation who said he suspected the young man was bragging on Twitter that he used a custom version of Nuclear Bot dubbed “TinyNuke” to steal funds from customers of French and Polish banks.
