In at least one case, he posted nude photos of a victim on the Myspace account of a friend of the victim, which Mijangos had also hacked, after she refused to comply with his demands.

To make matters worse, Mijangos also used the computers he controlled to spread his malware further, propagating to the people in his victims’ address books instant messages that appeared to come from friends and thereby inducing new victims to download his malware.

In it, we look at the methods used by perpetrators and the prosecutorial tools authorities have used to bring offenders to justice.

We hope that by highlighting the scale and scope of the problem, and the brutality of these cases for the many victims they affect, to spur a close look at both state and federal laws under which these cases get prosecuted.

Mijangos’ actions constitute serial online sexual abuse—something, we shall argue, akin to virtual sexual assault.

As the prosecutor said in the case, Mijangos “play[ed] psychological games with his victims” His victims reported signs of immense psychological stress, noting that they had “trouble concentrating, appetite change, increased school and family stress, lack of trust in others, and a desire to be alone.” * * * As bizarre as the Mijangos case may sound, his conduct turns out to be not all that unusual.

The perpetrator wanted a pornographic video of the victim.

And if she did not send it within one day, he threatened to publish the images already in his possession, and “let [her] family know about [her] dark side.” If she contacted law enforcement, he promised he would publish the photos on the Internet too.

We searched dockets and news stories for criminal cases in which one person used a computer network to extort another into producing pornography or engaging in sexual activity.

We found nearly 80 such cases involving, by conservative estimates, more than 3,000 victims. Prosecutors colloquially call this sort of crime “sextortion.” And while not all cases are as sophisticated as this one, a great many sextortion cases have taken place―in federal courts, in state courts, and internationally―over a relatively short span of time.

This is the new playground.” But while the FBI has issued numerous warnings about sextortion, the government publishes no data on the subject.

Unlike its close cousin, the form of nonconsensual pornography known as “revenge porn,” the problem of sextortion has not received sustained press attention or action in numerous state legislatures, in part because with few exceptions, sextortion victims have chosen to remain anonymous, as the law in most jurisdictions permits. The 78 cases we reviewed alone involve at least 1,397 victims, and this is undoubtedly just the tip of the iceberg.

As defined in the Mijangos court documents, sextortion is “a form of extortion and/or blackmail” wherein “the item or service requested/demanded is the performance of a sexual act.” The crime takes a number of different forms, and it gets prosecuted under a number of different statutes.
