Having lost more hours to reading criminal complaints over the years than I care to remember, I can confidently state that I have never encountered one as entertaining and complete as the one that dropped today, charging a 22 y/o Oregon man with operating "Rapper Bot," a huge IoT botnet blamed for the Twitter/X DDoS attack in March 2025.

As the complaint states in delicious detail, the accused and his alleged co-conspirator discussed at length on Telegram how to stay off the radar of law enforcement. Here's a snippet from the story:

“Both FOLTZ and Slaykings were very dismissive of attention seeking activities, the most extreme of which, in their view, was to launch DDoS attacks against the website of the prominent cyber security journalist Brian Krebs,” Peterson wrote in the criminal complaint.

“You see, they’ll get themselves [expletive],” Slaykings wrote in response to Foltz’s comments about Forky and Aisuru bringing too much heat on themselves.

“Prob cuz [redacted] hit krebs,” Foltz wrote in reply.

“Going against Krebs isn’t a good move,” Slaykings concurred. “It isn’t about being a [expletive] or afraid, you just get a lot of problems for zero money. Childish, but good. Let them die.”

“Ye, it’s good tho, they will die,” Foltz replied.

The government states that just prior to Foltz’s arrest, Rapper Bot had enslaved an estimated 65,000 devices globally. That may sound like a lot, but the complaint notes the defendants weren’t interested in making headlines for building the world’s largest or most powerful botnet.

Quite the contrary: The complaint asserts that the accused took care to maintain their botnet in a “Goldilocks” size — ensuring that “the number of devices afforded powerful attacks while still being manageable to control and, in the hopes of Foltz and his partners, small enough to not be detected.”

The complaint states that several days later, Foltz and Slaykings returned to discussing what that they expected to befall their rival group, with Slaykings stating, “Krebs is very revenge. He won’t stop until they are [expletive] to the bone.”

“Surprised they have any bots left,” Foltz answered.

“Krebs is not the one you want to have on your back. Not because he is scary or something, just because he will not give up UNTIL you are [expletive] [expletive]. Proved it with Mirai and many other cases.”
