UCF student arrested by FBI

Be careful what you tweet, it could result in a visit from the FBI.

That's what happened to one UCF student a month after he sent a tweet to the FBI Press Office.

Computer engineering major Scott Matthew Arciszewski was arrested by FBI special agents on Tuesday for an "alleged computer intrusion" of InfraGard, an FBI program "designed to establish an alliance between academia, private industry and the FBI," according to a press release from the FBI's Tampa Division.

Arciszewski was released from custody late Tuesday after making an initial appearance in Orlando federal court before United States Magistrate Judge Donald Dietrich, according to Special Agent Dave Couvertier, the public affairs officer for the FBI's Tampa Field Office.

The FBI tracked Arciszewski for about a month after he allegedly tried to hack into the website. He also sent a message to the Twitter account for the FBI Press Office and created a post on his personal website questioning the security of InfraGard's Tampa chapter.

"The FBI cyber crime unit's intelligence-gathering efforts and counter-hacking techniques alerted us to potential plot," Couvertier said in an email. "In anticipation of the attack, we contacted the website host who supported our efforts to protect their info and system."

Under the username voodooKobra, Arciszewski tweeted, "InfraGard Tampa has one hell of an exploit," to the FBI Press Office account.

On his personal website, he posted, "Not only is [InfraGard's] site not safe, secure, or hacker-proof, but it took me less than 5 minutes to find a vulnerability that could potentially allow anyone to hack in and obtain employee login information, which could in turn be used to gain access to other FBI-affiliate websites and compromise national security. Imagine what damage could be caused if a sophisticated hacker decided to look at their website."

He also tweeted from voodooKobra, on June 21, "No matter how intimidating a website or a website's owners might be, that doesn't mean it's necessarily secure."

His most recent tweet following his arrest?

"I have had a very bad day. I am stressed to the max.
