'Aaron's Law' could have unintended consequences


The suicide of Internet wunderkind Aaron Swartz has prompted a variation on the classic "there-ought-to-be-a-law" response to tragedy. In this case, it's, "There ought to be an amendment to the law," to prevent what critics have called overzealous prosecution and vastly disproportionate sentencing guidelines.
The law in this case is the Computer Fraud and Abuse Act (CFAA), invoked by federal prosecutors to bring a 13-count indictment against Swartz, 26, after he used the MIT computer network to download more than 4 million academic articles from the online archive JSTOR, allegedly without legal authorization, in violation of MIT's terms of service.
U.S. Rep. Zoe Lofgren (D-Calif.) filed a bill this week she called "Aaron's Law," that would exclude terms of service violations from the CFAA and wire fraud statutes. In a post on Reddit, the Internet forum that Swartz cofounded, Lofgren wrote that "using the law in this way could criminalize many everyday activities and allow for outlandishly severe penalties.
"A simple way to correct this dangerous legal interpretation is to change the CFAA and the wire fraud statutes to exclude terms of service violations," she wrote.
But several Internet security experts, while expressing sympathy for Swartz's family, say it is not so simple, and that Lofgren's proposal could end up being yet another example of the law of unintended consequences.

Jody Westby, an attorney and CEO of Global Cyber Risk, said Swartz's death could be blamed on overly zealous prosecution "that crushed a young man." But she said that the proposed amendment to the CFAA "is another form of overkill that would have terribly detrimental consequences."
"[The CFAA language regarding terms-of-service violations]Ã'Â is absolutely essential in arresting insiders who steal or misuse confidential or proprietary data they were not given access to, and also criminals who hack into computers or plant malware to steal credentials or exfiltrate data," Westby said.
Randy Sabett, an attorney with ZwillGen and an expert in information security and intellectual property, said: "To isolate this law as the showpiece cause of a terrible tragedy, and therefore wipe out an entire remedy for criminal activity and intent is not the way to go."
Swartz, the founder and director of Demand Progress, co-author of RSS and a former research fellow at Harvard's Center for Ethics, was an outspoken crusader for making information free on the Internet, and prosecutors say he had planned to make the articles he obtained available to the public for free, as a political statement about access to knowledge.
He was scheduled to go to trial in April, and could have faced as many as 35 years in prison and as much as $1 million in fines, although the U.S. Attorney's office had reportedly offered a plea bargain that would have resulted in six months of jail time.
However, since his death, U.S. Attorney Carmen Ortiz has faced a firestorm of criticism, including a petition demanding her removal, which this week reached 25,000 signatures, however the White House has increased the theshold for a response from 25,000 to 100,000 petitions.Ã'Â
Marcia Hofmann, a senior staff attorney at the Electronic Frontier Foundation (EFF), said in a blog post earlier this week that the CFAA is indeed badly flawed. "The government should never have thrown the book at Aaron for accessing MIT's network and downloading scholarly research," she wrote. "However, some extremely problematic elements of the law made it possible."
One of them is that the law doesn't clearly define what "authorization" to access protected computers means, she wrote. "Creative prosecutors have taken advantage of this confusion to craft criminal charges that aren't really about hacking a computer but instead (to) target other behavior the prosecutors don't like," she said, adding that a second major problem is that sentences for hacking crimes are far too severe.
Westby said there might be a need for the law's language to be more precise, and for sentencing guidelines to be adjusted. She suggested that Lofgren's bill should, "serve as a basis for Congressional hearings on what guidelines exist for prosecutors in handling CFAA cases."
But she said simply exempting terms-of-service violations from criminal penalties would be disastrous. "It would leave all businesses, individuals, and governments unable to use the CFAA to prosecute cybercriminals in circumstances where the perpetrator was violating terms of use, contractual obligations, or company policies."
"I do not say this with a hard heart. I lost a very close friend who committed suicide over extreme prosecutorial conduct over a relatively minor securities violation," she said. "What happened is that four boys lost their father. There are bounds of decency in prosecutorial conduct and certainly looking at damage should be a factor."
Sabett said if the penalties are indeed disproportionate, that is what should be changed. "Change the remedies," he said. "But don't wipe out a whole provision of the law. Any deterrent effect it would have against criminals would no longer exist."
A terrible tragedy should not eliminate the ability to bring charges for criminal behavior, he said. "Even if you say you're doing it for the common man -- that it is OK because it is for the greater good -- if it is a crime, then it is still a crime."

China could be behind Twitter password reset


Twitter sent notices of an attempted hacking to China-based foreign journalists and analysts just hours before apologizing for resetting the passwords of more users than necessary in a recent break-in of accounts.
The Voice of America reported Thursday that the emailed warnings did not say who was behind the hacking attempts. Chinese Internet users have had difficulty in accessing foreign websites and using virtual private networks (VPN) to avoid government censorship, the U.S.-funded VOA said.
Twitter routinely sends warnings when it believes a person's account has been hacked. The microblogging site then forces the person to reset his password. On Thursday, the company apologized for resetting more passwords than necessary to protect users from a recent hacking.
"In this case, we unintentionally reset passwords of a larger number of accounts, beyond those that we believed to have been compromised," Twitter said in a tweet. "We apologize for any inconvenience or confusion this may have caused."
Twitter, which did not respond to a request for comment, has provided no details on the hacking. However, VOA reported that journalists and analysts have been expecting a censorship crackdown as China's Communist Party begins meetings to set in motion a leadership change.
David Bandurski, head of the China Media Project in Hong Kong, told VOA he received a warning that his Twitter account had been hacked just as he was tweeting about Chinese President Hu Jintao's speech at the 18th Party Congress.
"I had someone else, a programmer, look at it and say that's a legit message from Twitter," Bandurski told VOA. "Beyond that I don't know what that means or who could be behind it. I have my guesses that I won't hazard, but I'm not sure what to say other than that it's an annoyance."
Contacted by email, Bandurski declined to provide more details. "I've been very careful to explain to reporters that I'm not speculating about what happened, that they need to find out from Twitter," he said.
Prolexic, a security vendor specializing in distributed denial of service (DDoS) attacks, said it had not seen any significant changes in activity out of China. "It has maintained its position as one of the top three countries originating DDoS traffic over the last 2 quarters," a spokesman said.
Hackers with stolen user names and passwords will hijack Twitter accounts to distribute links thatsend users to malicious websites. Cybercriminals are also opening accounts to tweet commands to malware controlling compromised PCs, McAfee reported recently in its second quarter Threats Report.
Overall, four in 10 social network users have been victims of cybercrime on the platforms, according Symantec's 2012 Norton Cybercrime Report. In addition, one in six reported that someone had hacked into their profile and pretended to be them.
A U.S. commission has fingered China as the biggest cyberthreat, due to relentless attacks against U.S. military systems and defense contractors. The U.S.-China Economic and Security Review Commission is scheduled to release its findings to Congress next month.
