The U.S. Department of Justice is pushing to make it easier for law enforcement to get warrants to hack into the computers of criminal suspects across the country. The move, which would alter federal court rules governing search warrants, comes amid increases in cases related to computer crimes. Investigators say they need more flexibility to get warrants to allow hacking in such cases, especially when multiple computers are involved or the government doesn’t know where the suspect’s computer is physically located. The Justice Department effort is raising questions among some technology advocates, who say the government should focus on fixing the holes in computer software that allow such hacking instead of exploiting them. Privacy advocates also warn government spyware could end up on innocent people’s computers if remote attacks are authorized against equipment whose ownership isn’t clear.

The government’s push for rule changes sheds light on law enforcement’s use of remote hacking techniques, which are being deployed more frequently but have been protected behind a veil of secrecy for years. In documents submitted by the government to the judicial system’s rule-making body this year, the government discussed using software to find suspected child pornographers who visited a U.S. site and concealed their identity using a strong anonymization tool called Tor. The government’s hacking tools—such as sending an email embedded with code that installs spying software — resemble those used by criminal hackers. The government doesn’t describe these methods as hacking, preferring instead to use terms like “remote access” and “network investigative techniques.” Right now, investigators who want to search property, including computers, generally need to get a warrant from a judge in the district where the property is located, according to federal court rules. In a computer investigation, that might not be possible, because criminals can hide behind anonymizing technologies. In cases involving botnets—groups of hijacked computers—investigators might also want to search many machines at once without getting that many warrants.

Some judges have already granted warrants in cases when authorities don’t know where the machine is. But at least one judge has denied an application in part because of the current rules. The department also wants warrants to be allowed for multiple computers at the same time, as well as for searches of many related storage, email and social media accounts at once, as long as those accounts are accessed by the computer being searched. “Remote searches of computers are often essential to the successful investigation” of computer crimes, Acting Assistant Attorney General Mythili Raman wrote in a letter to the judicial system’s rulemaking authority requesting the change in September. The government tries to obtain these “remote access warrants” mainly to “combat Internet anonymizing techniques,” the department said in a memo to the authority in March. Some groups have raised questions about law enforcement’s use of hacking technologies, arguing that such tools mean the government is failing to help fix software problems exploited by criminals. “It is crucial that we have a robust public debate about how the Fourth Amendment and federal law should limit the government’s use of malware and spyware within the U.S.,” said Nathan Wessler, a staff attorney at the American Civil Liberties Union who focuses on technology issues.

The British government has admitted that its practice of spying on confidential communications between lawyers and their clients was a breach of the European Convention on Human Rights (ECHR). Details of the controversial snooping emerged in November: lawyers suing Blighty over its rendition of two Libyan families to be tortured by the late and unlamented Gaddafi regime claimed Her Majesty's own lawyers seemed to have access to the defense team's emails. The families' briefs asked for a probe by the secretive Investigatory Powers Tribunal (IPT), a move that led to Wednesday's admission. "The concession the government has made today relates to the agencies' policies and procedures governing the handling of legally privileged communications and whether they are compatible with the ECHR," a government spokesman said in a statement to the media, via the Press Association. "In view of recent IPT judgments, we acknowledge that the policies applied since 2010 have not fully met the requirements of the ECHR, specifically Article 8. This includes a requirement that safeguards are made sufficiently public."

The guidelines revealed by the investigation showed that MI5 – which handles the UK's domestic security – had free reign to spy on highly private and sensitive lawyer-client conversations between April 2011 and January 2014. MI6, which handles foreign intelligence, had no rules on the matter either until 2011, and even those were considered void if "extremists" were involved. Britain's answer to the NSA, GCHQ, had rules against such spying, but they too were relaxed in 2011. "By allowing the intelligence agencies free rein to spy on communications between lawyers and their clients, the Government has endangered the fundamental British right to a fair trial," said Cori Crider, a director at the non-profit Reprieve and one of the lawyers for the Libyan families. "For too long, the security services have been allowed to snoop on those bringing cases against them when they speak to their lawyers. In doing so, they have violated a right that is centuries old in British common law. Today they have finally admitted they have been acting unlawfully for years."

Crider said it now seemed probable that UK snoopers had been listening in on the communications over the Libyan case. The British government hasn't admitted guilt, but it has at least acknowledged that it was doing something wrong – sort of. "It does not mean that there was any deliberate wrongdoing on the part of the security and intelligence agencies, which have always taken their obligation to protect legally privileged material extremely seriously," the government spokesman said. "Nor does it mean that any of the agencies' activities have prejudiced or in any way resulted in an abuse of process in any civil or criminal proceedings. The agencies will now work with the independent Interception of Communications Commissioner to ensure their policies satisfy all of the UK's human rights obligations." So that's all right, then.

Last month, at the request of the Department of Justice, the Courts approved changes to the obscure Rule 41 of the Federal Rules of Criminal Procedure, which governs search and seizure. By the nature of this obscure bureaucratic process, these rules become law unless Congress rejects the changes before December 1, 2016.Today I, along with my colleagues Senators Paul from Kentucky, Baldwin from Wisconsin, and Daines and Tester from Montana, am introducing the Stopping Mass Hacking (SMH) Act (bill, summary), a bill to protect millions of law-abiding Americans from a massive expansion of government hacking and surveillance. Join the conversation with #SMHact.

For law enforcement to conduct a remote electronic search, they generally need to plant malware in — i.e. hack — a device. These rule changes will allow the government to search millions of computers with the warrant of a single judge. To me, that’s clearly a policy change that’s outside the scope of an “administrative change,” and it is something that Congress should consider. An agency with the record of the Justice Department shouldn’t be able to wave its arms and grant itself entirely new powers.

These changes say that if law enforcement doesn’t know where an electronic device is located, a magistrate judge will now have the the authority to issue a warrant to remotely search the device, anywhere in the world. While it may be appropriate to address the issue of allowing a remote electronic search for a device at an unknown location, Congress needs to consider what protections must be in place to protect Americans’ digital security and privacy. This is a new and uncertain area of law, so there needs to be full and careful debate. The ACLU has a thorough discussion of the Fourth Amendment ramifications and the technological questions at issue with these kinds of searches.The second part of the change to Rule 41 would give a magistrate judge the authority to issue a single warrant that would authorize the search of an unlimited number — potentially thousands or millions — of devices, located anywhere in the world. These changes would dramatically expand the government’s hacking and surveillance authority. The American public should understand that these changes won’t just affect criminals: computer security experts and civil liberties advocates say the amendments would also dramatically expand the government’s ability to hack the electronic devices of law-abiding Americans if their devices were affected by a computer attack. Devices will be subject to search if their owners were victims of a botnet attack — so the government will be treating victims of hacking the same way they treat the perpetrators.

The first (and thus far only) roll-back of post-9/11 surveillance authorities was implemented over the weekend: The National Security Agency shuttered its program for collecting and holding the metadata of Americans’ phone calls under Section 215 of the Patriot Act. While bulk collection under Section 215 has ended, the government can obtain access to this information under the procedures specified in the USA Freedom Act. Indeed, some experts have argued that the Agency likely has access to more metadata because its earlier dragnet didn’t cover cell phones or Internet calling. In addition, the metadata of calls made by an individual in the United States to someone overseas and vice versa can still be collected in bulk — this takes place abroad under Executive Order 12333. No doubt the NSA wishes that this was the end of the surveillance reform story and the Paris attacks initially gave them an opening. John Brennan, the Director of the CIA, implied that the attacks were somehow related to “hand wringing” about spying and Sen. Tom Cotton (R-Ark.) introduced a bill to delay the shut down of the 215 program. Opponents of encryption were quick to say: “I told you so.”

But the facts that have emerged thus far tell a different story. It appears that much of the planning took place IRL (that’s “in real life” for those of you who don’t have teenagers). The attackers, several of whom were on law enforcement’s radar, communicated openly over the Internet. If France ever has a 9/11 Commission-type inquiry, it could well conclude that the Paris attacks were a failure of the intelligence agencies rather than a failure of intelligence authorities. Despite the passage of the USA Freedom Act, US surveillance authorities have remained largely intact. Section 702 of the FISA Amendments Act — which is the basis of programs like PRISM and the NSA’s Upstream collection of information from Internet cables — sunsets in the summer of 2017. While it’s difficult to predict the political environment that far out, meaningful reform of Section 702 faces significant obstacles. Unlike the Section 215 program, which was clearly aimed at Americans, Section 702 is supposedly targeted at foreigners and only picks up information about Americans “incidentally.” The NSA has refused to provide an estimate of how many Americans’ information it collects under Section 702, despite repeated requests from lawmakers and most recently a large cohort of advocates. The Section 215 program was held illegal by two federal courts (here and here), but civil attempts to challenge Section 702 have run into standing barriers. Finally, while two review panels concluded that the Section 215 program provided little counterterrorism benefit (here and here), they found that the Section 702 program had been useful.

There is, nonetheless, some pressure to narrow the reach of Section 702. The recent decision by the European Court of Justice in the safe harbor case suggests that data flows between Europe and the US may be restricted unless the PRISM program is modified to protect the information of Europeans (see here, here, and here for discussion of the decision and reform options). Pressure from Internet companies whose business is suffering — estimates run to the tune of $35 to 180 billion — as a result of disclosures about NSA spying may also nudge lawmakers towards reform. One of the courts currently considering criminal cases which rely on evidence derived from Section 702 surveillance may hold the program unconstitutional either on the basis of the Fourth Amendment or Article III for the reasons set out in this Brennan Center report. A federal district court in Colorado recently rejected such a challenge, although as explained in Steve’s post, the decision did not seriously explore the issues. Further litigation in the European courts too could have an impact on the debate.

Throughout the past ten years, the FBI has at varying points in time maintained a particularly close relationship with Best Buy officials and used the company’s Geek Squad employees as informants. But the FBI refuses to confirm or deny key information about how the agency may potentially circumvent computer owners’ Fourth Amendment rights. The Electronic Frontier Foundation (EFF) obtained a handful of documents in response to a Freedom of Information Act (FOIA) lawsuit filed in February of last year. EFF says they show the relationship between the FBI and Geek Squad employees is much “cozier” than they thought.

In court filings, the defense mentioned there were “eight FBI informants at Geek Squad City” from 2007 to 2012. Multiple employees received payments ranging from $500-1000 for work as informants.

There is no evidence that FBI obtained warrants before the Geek Squad informants searched computers they were repairing. It is believed Geek Squad employees routinely search unallocated space for any illegal content that may be on a device and then alert the FBI after conducting “fishing expeditions” for criminal activity, and this is what the FBI trains them to do. EFF sought “records about the extent to which [the FBI] directs and trains Best Buy employees to conduct warrantless searches of people’s devices.” As is clear, the government stonewalled EFF and only released documents that were already referred to by news media. The FBI neither confirmed nor denied whether the agency has “similar relationships with other computer repair facilities or businesses.” The FBI also would not produce any documents that detailed procedures or “training materials” for cultivating informants at computer repair facilities.
