CD copy-protection vendor SunnComm Technologies has said that it will not sue J. Alex Halderman under the DMCA for publishing a paper that disclosed weaknesses in the company's latest MediaMax protection technology. The final concession comes after a week of off-again, on-again threats against the Princeton computer science graduate student. EFF had offered to represent Mr. Halderman if SunnComm made good on its earlier litigation threats.

"We're glad that cooler heads prevailed at SunnComm," said Fred von Lohmann, EFF senior staff attorney. "But this is just the latest example of the chill that the DMCA has injected into the computer security research community. These irresponsible legal threats imperil not only First Amendment values, but also scare future generations of researchers away from important computer security investigations."
