Bradley Manning Verdict
by Shelley 30 Jul '13

30 Jul '13

-Convicted of multiple Espionage Act violations -Acquitted of 'aiding the enemy' charge http://www.theguardian.com/world/2013/jul/30/bradley-manning-wikileaks-judg… Ed Pilkington at Fort Meade theguardian.com, Tuesday 30 July 2013 13.30 EDT Bradley Manning has already spent 1,157 days in detention since his arrest in May 2010. Bradley Manning, the source of the massive WikiLeaks trove of secret disclosures, faces a possible maximum sentence of more than 130 years in military jail after he was convicted of most charges on which he stood trial. Colonel Denise Lind, the military judge presiding over the court martial of the US soldier, delivered her verdict in curt and pointed language. "Guilty, guilty, guilty, guilty," she repeated over and over, as the reality of a prolonged prison sentence for Manning – on top of the three years he has already spent in detention – dawned. The one ray of light in an otherwise bleak outcome for Manning was that he was found not guilty of the single most serious charge against him – that he knowingly "aided the enemy", in practice al-Qaida, by disclosing information to the WikiLeaks website that in turn made it accessible to all users including enemy groups. Lind's decision to avoid setting a precedent by applying the swingeing "aiding the enemy" charge to an official leaker will invoke a sigh of relief from news organisations and civil liberties groups who had feared a guilty verdict would send a chill across public interest journalism. The judge also found Manning not guilty of having leaked an encrypted copy of a video of a US air strike in the Farah province of Aghanistan in which many civilians died. Manning's defence team had argued vociferously that he was not the source of this video, though the soldier did admit to later disclosure of an unencrypted version of the video and related documents. Lind also accepted Manning's version of several of the key dates in the WikiLeaks disclosures, and took some of the edge from other less serious charges. But the overriding toughness of the verdict remains: the soldier was found guilty in their entirety of 17 out of the 22 counts against him, and of an amended version of four others. Manning was also found guilty of "wrongfully and wantonly" causing to be published on the internet intelligence belonging to the US, "having knowledge that intelligence published on the internet is accesible to the enemy". That guilty ruling could still have widest ramifications for news organisations working on investigations relating to US national security. Once the counts are added up, the prospects for the Manning are bleak. Barring reduction of sentence for mitigation, which becomes the subject of another mini-trial dedicated to sentencing that starts tomorrow, Manning will face a substantial chunk of his adult life in military custody. He has already spent 1,157 days in detention since his arrest in May 2010 – most recently in Fort Leavenworth in Kansas – which will be deducted from his eventual sentence. A further 112 days will be taken off the sentence as part of a pre-trial ruling in which Lind compensated him for the excessively harsh treatment he endured at the Quantico marine base in Virginia between July 2010 and April 2011. He was kept on suicide watch for long stretches despite expert opinion from military psychiatrists who deemed him to be at low risk of self-harm, and at one point was forced to strip naked at night in conditions that the UN denounced as a form of torture. Lind has indicated that she will go straight into the sentencing phase of the trial, in which both defence and prosecution lawyers will call new witnesses. This is being seen as the critical stage of the trial for Manning's defence: the soldier admitted months ago to being the source of the WikiLeaks disclosures, and much of the defence strategy has been focused on attempting to reduce his sentence through mitigation. With that in mind, the soldier's main counsel, David Coombs, is likely to present evidence during the sentencing phase that Manning was in a fragile emotional state at the time he began leaking and was struggling with issues over his sexuality. In pre-trial hearings, the defence has argued that despite his at times erratic behaviour, the accused was offered very little support or counselling from his superiors at Forward Operating Base Hammer outside Baghdad. The outcome will now be pored over by government agencies, lawyers, journalists and civil liberties groups for its implications for whistleblowing, investigative reporting and the guarding of state secrets in the digital age. By passing to WikiLeaks more than 700,000 documents, Manning became the first mass digital leaker in history, opening a whole new chapter in the age-old tug-of-war between government secrecy and the public's right to information in a democracy. Among those who will also be closely analysing the verdict are Edward Snowden, the former NSA contractor who has disclosed the existence of secret government dragnets of the phone records of millions of Americans, who has indicated that the treatment of Manning was one reason for his decision to seek asylum in another country rather than face similar aggressive prosecution in America. The British government will also be dissecting the courtroom results after the Guardian disclosed that Manning is a joint British American citizen. Another party that will be intimately engaged with the verdict is WikiLeaks, and its founder, Julian Assange. They have been the subject of a secret grand jury investigation in Virginia that has been looking into whether to prosecute them for their role in the Manning disclosures. WikiLeaks and Assange were mentioned repeatedly during the trial by the US government which tried to prove that the anti-secrecy organisation had directly steered Manning in his leaking activities, an allegation strongly denied by the accused. Prosecutors drew heavily on still classified web conversations between Manning and an individual going by the name of "Press Association", whom the government alleges was Assange.

Max Blumenthal on Security Forum
by Eugen Leitl 30 Jul '13

30 Jul '13

(it's Alternet, so caveat lector) http://www.alternet.org/tea-party-and-right/shocking-extermination-fantasie… Shocking 'Extermination' Fantasies By the People Running America's Empire on Full Display at Aspen Summit Security Forum participants expressed total confidence in American empire, but could not contain their panic at the mention of Snowden. July 25, 2013 | Seated on a stool before an audience packed with spooks, lawmakers, lawyers and mercenaries, CNN’s Wolf Blitzer introduced recently retired CENTCOM chief General James Mattis. “I’ve worked with him and I’ve worked with his predecessors,” Blitzer said of Mattis. “I know how hard it is to run an operation like this.” Reminding the crowd that CENTCOM is “really, really important,” Blitzer urged them to celebrate Mattis: “Let’s give the general a round of applause.” Following the gales of cheering that resounded from the room, Mattis, the gruff 40-year Marine veteran who once volunteered his opinion that “it’s fun to shoot some people,” outlined the challenge ahead. The “war on terror” that began on 9/11 has no discernable end, he said, likening it to the “the constant skirmishing between [the US cavalry] and the Indians” during the genocidal Indian Wars of the 19th century. “The skirmishing will go on likely for a generation,” Mattis declared. Mattis’ remarks, made beside a cable news personality who acted more like a sidekick than a journalist, set the tone for the entire 2013 Aspen Security Forum this July. A project of the Aspen Institute, the Security Forum brought together the key figures behind America’s vast national security state, from military chieftains like Mattis to embattled National Security Agency Chief General Keith Alexander to top FBI and CIA officials, along with the bookish functionaries attempting to establish legal groundwork for expanding the war on terror. Partisan lines and ideological disagreements faded away inside the darkened conference hall, as a parade of American securitocrats from administrations both past and present appeared on stage to defend endless global warfare and total information awareness while uniting in a single voice of condemnation against a single whistleblower bunkered inside the waiting room of Moscow International Airport: Edward Snowden. With perhaps one notable exception, none of the high-flying reporters junketed to Aspen to act as interlocutors seemed terribly interested in interrogating the logic of the war on terror. The spectacle was a perfect window into the world of access journalism, with media professionals brown-nosing national security elites committed to secrecy and surveillance, avoiding overly adversarial questions but making sure to ask the requisite question about how much Snowden has caused terrorists to change their behavior. Jeff Harris, the communications director for the Aspen Institute, did not respond to questions I submitted about whether the journalists who participated in the Security Forum accepted fees. (It is likely that all relied on Aspen to at least cover lodging and travel costs). CNN sponsored the forum through a special new website called CNN Security Clearance, promoting the event through Twitter and specially commissioned op-eds from participating national security figures like former CIA director John McLaughlin. Another forum sponsor was Academi, the private mercenary corporation formerly known as Blackwater. In fact, Academi is Blackwater’s third incarnation (it was first renamed “Xe”) since revelations of widespread human rights abuses and possible war crimes in Iraq and Afghanistan threw the mercenary firm into full damage control mode. The Aspen Institute did not respond to my questions about whether accepting sponsorship from such an unsavory entity fit within its ethical guidelines. 'Exterminating People' John Ashcroft, the former Attorney General who prosecuted the war on terror under the administration of George W. Bush, appeared at Aspen as a board member of Academi. Responding to a question about U.S. over-reliance on the “kinetic” approach of drone strikes and special forces, Ashcroft reminded the audience that the U.S. also likes to torture terror suspects, not just “exterminate” them. “It's not true that we have relied solely on the kinetic option,” Ashcroft insisted. “We wouldn't have so many detainees if we'd relied on the ability to exterminate people…We've had a blended and nuanced approach and for the guy who's on the other end of a Hellfire missile he doesn't see that as a nuance.” Hearty laughs erupted from the crowd and fellow panelists. With a broad smile on her face, moderator Catherine Herridge of Fox News joked to Ashcroft, “You have a way with words.” But Ashcroft was not done. He proceeded to boast about the pain inflicted on detainees during long CIA torture sessions: “And maybe there are people who wish they were on the end of one of those missiles.” Competing with Ashcroft for the High Authoritarian prize was former NSA chief Michael Hayden, who emphasized the importance of Obama’s drone assassinations, at least in countries the U.S. has deemed to be Al Qaeda havens. “Here's the strategic question,” Hayden said. “People in Pakistan? I think that's very clear. Kill 'em. People in Yemen? The same. Kill 'em.” “We don’t smoke [drug] cartel leaders but personally I’d support it,” remarked Philip Mudd, the former deputy director of Bush’s Counterterrorism Center, earning more guffaws from his fellow panelists and from Herridge. Ironically, Mudd was attempting to argue that counter-terror should no longer be a top U.S. security priority because it poses less of a threat to Americans than synthetic drugs and child obesity. Reflection was not on the agenda for most of the Security Forum’s participants. When asked by a former US ambassador to Denmark the seminal question “This is a great country, why are we always the bad guy?,” Mudd replied, “They think that anything the U.S. does [in the Middle East], even though we helped Muslim communities in Bosnia and Kuwait, everything is rewritten to make us the bad guys.” The clamoring about U.S. invasions, drone strikes, bankrolling of Israel’s occupation, and general political meddling, could all be written off as fevered anti-Americanism borne from the desert canyons of the paranoid Arab mind. And the wars could go on. Delusions of Empire Throughout the three days of the Security Forum, the almost uniformly white cast of speakers were called on to discuss recent geopolitical developments, from "Eye-rak" and "Eye-ran" to Egypt, where a military coup had just toppled the first elected government in the country’s history. Mattis carefully toed the line of the Obama administration, describing the overthrow of Egypt’s government not as a coup, but as “military muscle saddled on top of this popular uprising.” Warning that using terms like “coup” could lead to a reduction in U.S. aid to Egypt, where the military controls about one-third of the country’s economy, Mattis warned, “We have to be very careful about passing laws with certain words when the reality of the world won’t allow you to.” Wolf Blitzer mentioned that Egypt’s new military-imposed foreign minister, Nabil Fahmy, had been a fixture in Washington during the Mubarak days. “These are people the West knows, the U.S. knows,” he said of the new cabinet in Cairo. “I assume from the U.S. perspective, the United States is so much more happy with this.” Later, one of the few Arab participants in the forum, Al Jazeera DC bureau chief Abderrahim Foukara, claimed that the Arab revolts were inspired by the U.S. invasion of Iraq. “The iconic image of Saddam being pulled out of a hole did something to the dynamic between ruler and ruled in the Arab world,” Foukara claimed. With the revolts blurring the old boundaries imposed on the Arab world during the late colonial era, former CIA director John McLaughlin rose from the audience to call for the U.S. to form a secret, Sikes-Picot-style commission to draw up a new set of borders. “The American government should now have such a group asking how we should manage those lines and what should those lines be,” McLaughlin told the panelists, who dismissed the idea of a new Great Game even as they discussed tactics for preserving U.S. dominance in the Middle East. ABC’s Chris Isham asked Jim Jeffrey, the former U.S. ambassador to Iraq, why, with a recession on its hands and Middle Eastern societies spiraling out of control, should the U.S. remain militarily involved in the region. Without hesitation, Jeffrey rattled off the reasons: Saudi Arabia, Turkey, Israel, and “world oil markets.” “What could we have done better?” Isham asked the ambassador. “Probably not too much.” NSA Heroes, Saving Lives of Potential Consumers While participants in the Security Forum expressed total confidence in American empire, they could not contain their panic, outrage, and fear at the mere mention of Snowden. “Make no mistake about it: These are great people who we’re slamming and tarnishing and it’s wrong. They’re the heroes, not this other and these leakers!” NSA chief General Keith Alexander proclaimed, earning raucous applause from the crowd. Snowden’s leaks had prompted a rare public appearance from Alexander, forcing the normally imperious spy chief into the spotlight to defend his agency’s Panopticon-style programs and its dubious mechanisms of legal review. Fortunately for him, NBC’s Pete Williams offered him the opportunity to lash out at Snowden and the media that reported the leaks, asking whether the "terrorists” (who presumably already knew they were being spied on) had changed their behavior as a result of the leaks. “We have concrete proof that terrorists are taking action, making changes, and it’s gonna make our job harder,” Alexander declared, offering nothing to support his claim. Alexander appeared in full military regalia, with colorful decorations and medallions covering his left breast. Casting himself as a stern but caring father who has the best interests of all Americans at heart, even if he can't fully disclose his methods, he turned to the crowd and explained, “The bad guys…hide amongst us to kill our people. Our job is to stop them without impacting your civil liberties and privacy and these programs are set up to do that.” “The reason we use secrecy is not to hide it from the American people, but to hide it from the people who walk among you and are trying to kill you,” Alexander insisted. Corporations like AT&T, Google and Microsoft that had been compelled to hand over customer data to the NSA “know that we’re saving lives,” the general claimed. With a straight face, he continued, “And that’s good for business because there’s more people out there who can buy their products.” Self-Reporting So who were the "bad guys” who “walk among us,” and how could Americans be sure they had not been ensnared by the NSA’s all-encompassing spying regime, either inadvertently or intentionally? Nearly all the Security Forum participants involved in domestic surveillance responded to this question by insisting that the NSA had the world’s most rigorous program of oversight, pointing to Congress and the Foreign Intelligence Surveillance Act (FISA) courts as the best and only means of ensuring that “mistakes” are corrected. “We have more oversight on this [PRISM] program than any other program in any government that I’m aware of,” Alexander proclaimed, ramming home a talking point repeated throughout the forum. “I can assure these are some of the judges who are renowned for holding the government to a very high standard,” John Carlin, the Assistant US Attorney General for National Security, stated. But in the last year, FISA courts received 1,856 applications for surveillance from the government. In 100 percent of cases, they were approved. As for Congress, only two senators, Ron Wyden and Mark Udall, demanded the NSA explain why PRISM was necessary or questioned its legality. Despite the fact that the entire regime of oversight was a rubber stamp, or perhaps because of it, none of those who appeared at the Security Forum to defend it were willing to consider any forum of independent civilian review. “You have to do [domestic surveillance] within a closed bubble in order to do it effectively,” Dennis Blair, the director of National Intelligence conceded under sustained grilling from the Washington Post’s Barton Gellman, one of the reporters who broke Snowden’s leaks and perhaps the only journalist at the Security Forum who subjected participants to tough scrutiny. When Gellman reminded Alexander that none of the oversight mechanisms currently in place could determine if the NSA had improperly targeted American citizens with no involvement in terror-related activity, the general declared, “we self-report those mistakes.” “It can't be, let's just stop doing it, cause we know, that doesn't work,” Alexander maintained. “We've got to have some program like [PRISM].” The wars would go on, and so would the spying. Reinstituting Public Confidence During a panel on inter-agency coordination of counter-terror efforts, Mike Leiter, the former director of the National Counterterrorism Center (NCC), suggested that one of the best means of preserving America’s vast and constantly expanding spying apparatus was “by reinstituting faith among the public in our oversight.” Even as current NCC director Matthew Olsen conceded, “There really are limits in how transparent we can be,” Leiter demanded that the government “give the public confidence that there’s oversight. Since leaving the NCC, Leiter has become the senior counsel of Palantir Technologies, a private security contractor that conducts espionage on behalf of the FBI, CIA, financial institutions, the LAPD and the NYPD, among others. In 2011, Palantir spearheaded a dirty tricks campaign against critics of the U.S. Chamber of Commerce, including journalists, compiling electronic dossiers intended to smear them. Palantir’s target list included progressive groups like Think Progress, SEIU and U.S. Chamber Watch. In the friendly confines of the Aspen Institute’s Security Forum, Leiter did his best to burnish his company’s tarnished image, and do some damage control on behalf of the national security apparatus it depends on for contracts. Like most other participants, Leiter appeared in smart casual dress, with an open collar, loafers, a loose-fitting jacket and slacks. “Just seeing us here,” he said, “that inspires [public] confidence, because we’re not a bunch of ogres.” Max Blumenthal is the author of Republican Gomorrah (Basic/Nation Books, 2009).

It is important to understand that it is not a crypto accelerator. It is a place to store keys and small pieces of data (like hashes, counters) where it's difficult for someone to extract them even if they have physical access. The TPM is designed to support trusted computing, a rather splendid set of extensions to the x86 architecture that let you do remote attestation, software sealing and other things. Or at least it would be splendid if it had been really finished off and pushed to completion by the designers. Unfortunately due to various political issues it exists in a quasi-finished, semi-broken state which only experts can use. Without a doubt you have never run any software in a TC environment. As part of that role, the TPM provides some permanent storage in the form of NVRAM. Because the TPM is designed to be as cheap as possible, it has a limited number of write cycles. Normally you're meant to store Intel TXT launch control policies and sealed keys there, but Pond uses it in a different way by storing keys there that it encrypts local data with. By erasing the key in the TPM chips memory area, the data on disk is effectively destroyed too. This is useful because modern "disks" are often SSD drives, or physical metal disks that use log structured file systems. Because flash memory has a limited number of write cycles per cell, internally SSDs have firmware that remap writes from logical addresses to different physical addresses, the goal is to avoid wearing down the drive and extend its useful life. Normally it doesn't matter, but if you want to delete data such that it's really really gone, it obviously poses a problem. Using TPM NVRAM solves it, albiet, at a high usability cost. *note: actual tamper resistance of real-world TPM chips is not something that seems to have been studied much On Tue, Jul 30, 2013 at 1:27 PM, Wendell <w(a)grabhive.com> wrote: > Can you explain this process for those of us not too familiar with TPM > chips? > > -wendell > > grabhive.com | twitter.com/grabhive | gpg: 6C0C9411 > > On Jul 30, 2013, at 10:40 AM, Mike Hearn wrote: > > > As a testament to the seriousness with which Pond takes forward > security, it can use the NVRAM in a TPM chip to reliably destroy keys for > data that an SSD device might have otherwise made un-erasable. > ------------------------------------------------------------------------------ Get your SQL database under version control now!
