Trump Mobile, a cellular service founded by Donald Trump Jr. and Eric Trump, has been hacked, according to multiple reports , exposing the personal information of more than 3,000 customers, including a high-ranking Trump Organization executive.

A newly established hacking group known as BYOD conducted the breach, Straight Arrow News reported, adding the group shared the exposed data on a dark web site last week in addition to a statement that detailed the purported breach.

The group seemed to detail internal Trump Mobile communications in the statement, saying Trump Mobile was informed of the breach and acknowledged it did not have a team to handle the hack.

The group encourages dark web users to view data on “all 3,615 customers” and that “we (and them) certainly aren’t stopping you.”

PCMag identified three customers in the hack who confirmed they interacted with Trump Mobile at some point, noting one customer acknowledged the leaked file accurately showed they canceled the “30 Day Unlimited Talk Text Data” plan for Trump Mobile.

BYOD told PCMag it installed a Remote Access Trojan on a Liberty Mobile employee’s device that allowed it to remotely hijack their computer (Liberty Mobile is the operator behind Trump Mobile).

Personal details about Eric Brunnett, vice president and chief information officer for the Trump Organization, were exposed in the hack, according to Straight Arrow News.

Forbes has reached out to Trump Mobile for comment.

It does not appear Trump Mobile has recovered from the hack as of Tuesday, as a BYOD representative claimed to Straight Arrow News the group still has access to Trump Mobile’s backend dashboard.

YouTubers Coffeezilla and Cr1TiKaL detailed an exploitable software flaw on Trump Mobile’s website earlier this year, one that could allegedly be used to expose customer data. Trump Mobile claimed later it fixed the flaw, though there is speculation BYOD breached the website using the same exploit, PCMag reported, noting a separate hacking group claimed last month to have stolen data from 4,000 Trump Mobile users. Trump Mobile’s website says it offers a $47.45 per month plan for nationwide coverage, roadside assistance, telehealth access and more. The company has also promoted its T1 phone, a $750 gold-colored Android smartphone that has gained notoriety for delayed deliveries and for being built by Taiwanese company HTC even though Trump Mobile first marketed the device as being made in the U.S.
