Police in Arizona have arrested a man who claimed responsibility for cyberattacks on city of Madison and Dane County Internet resources following the fatal shooting of a 19-year-old man by a Madison police officer.
Madison police Detective Cynthia Murphy said Monday that Randall C. Tucker, 20, of Apache Junction, Arizona, calls himself the “Bitcoin Baron” and said he was behind cyberattacks on city computers in Madison.
“He is a suspect we’re looking at and claimed credit for the attack on Twitter, repeatedly,” said Murphy, who investigates computer-related crime for the Madison Police Department.
She said MPD is investigating the case along with the FBI.
The March 9 cyberattack on the city of Madison and Dane County at times blocked or disrupted official communications, including email and some police and fire dispatch services.
It followed the shooting death of Tony Robinson by Police Officer Matthew Kenny at a home on Madison’s East Side.
Someone calling himself Bitcoin Baron called the Milwaukee Journal Sentinel the following day and claimed responsibility. The hacker activist group Anonymous had also claimed responsibility.
According to a report last week by KNXV-TV in Phoenix, police executed a search warrant on Thursday at Tucker’s home following a six-month investigation, launched when a video was posted on YouTube in October threatening a cyberattack on Arizona government computer systems unless certain actions were taken in a child protection case.
When the demanded actions weren’t taken, the attack occurred, according to the search warrant, KNXV reported.
The person whose YouTube account was used to post the videos told police that he was ordered to post the videos or his business website would be taken down. When he initially refused, his website went offline, the search warrant states.
The television station’s report also details exchanges on Twitter in which the Bitcoin Baron exchanged comments with another hacker, who later referred to the Baron by the name Randy Tucker.
Though tweets related to the Madison cyberattack no longer appear in two Twitter accounts that were used by Tucker, other tweets indicate that he was involved in efforts to take down Sea World’s website and sites that peddled child pornography.
