The bumbling Penn State drug-dealing frat bros used a not-so-secret app to plot out cocaine deals – making it easier for investigators to nab the illicit trafficking scheme, according to court docs.

Lucrative drug deals were hashed out on Snapchat and used traceable cash apps to exchange thousands of dollars in payments for massive amounts of cocaine, the documents claim.

Agostino Abbatiello, the 24-year-old alleged ringleader of the campus conspiracy, used Snapchat “to facilitate the delivery of cocaine to known persons,” according to the docs.

Another Penn State student implicated in the scam, 22-year-old Mohammed Huraibi, testified before the Grand Jury that he set up a purchase of around 100 grams of coke for $4,000 from Abbatiello using Snapchat, the docs claim.

Abbatiello is now being held without bail.

His dad, Mario Abbatiello, told The Post Tuesday: “We have no comment. We have nothing to do with this. We have no comment.”

Thomas Robinson, 23, one of more than a dozen charged in the trafficking operation, was busted in December 2024 after authorities were tipped off that he was accepting cash payments through Venmo using his real name, according to court documents seen by NBC News.
