Testosterone Pit - Home - The Other Reason Why IBM Throws A Billion At Linux ... - 0 views

  • IBM announced today that it would throw another billion at Linux, the open-source operating system, to run its Power System servers. The first time it had thrown a billion at Linux was in 2001, when Linux was a crazy, untested, even ludicrous proposition for the corporate world. So the moolah back then didn’t go to Linux itself, which was free, but to related technologies across hardware, software, and service, including things like sales and advertising – and into IBM’s partnership with Red Hat which was developing its enterprise operating system, Red Hat Enterprise Linux. “It helped start a flurry of innovation that has never slowed,” said Jim Zemlin, executive director of the Linux Foundation. IBM claims that the investment would “help clients capitalize on big data and cloud computing with modern systems built to handle the new wave of applications coming to the data center in the post-PC era.” Some of the moolah will be plowed into the Power Systems Linux Center in Montpellier, France, which opened today. IBM’s first Power Systems Linux Center opened in Beijing in May. IBM may be trying to make hay of the ongoing revelations that have shown that the NSA and other intelligence organizations in the US and elsewhere have roped in American tech companies of all stripes with huge contracts to perfect a seamless spy network. They even include physical aspects of surveillance, such as license plate scanners and cameras, which are everywhere [read.... Surveillance Society: If You Drive, You Get Tracked].
  • It would be an enormous competitive advantage for an IBM salesperson to walk into a government or corporate IT department and sell Big Data servers that don’t run on Windows, but on Linux. With the Windows 8 debacle now in public view, IBM salespeople don’t even have to mention it. In the hope of stemming the pernicious revenue decline their employer has been suffering from, they can politely and professionally hype the security benefits of IBM’s systems and mention in passing the comforting fact that some of it would be developed in the Power Systems Linux Centers in Montpellier and Beijing. Alas, Linux too is tarnished. The backdoors are there, though the code can be inspected, unlike Windows code. And then there is Security-Enhanced Linux (SELinux), which was integrated into the Linux kernel in 2003. It provides a mechanism for supporting “access control” (a backdoor) and “security policies.” Who developed SELinux? Um, the NSA – which helpfully discloses some details on its own website (emphasis mine): The results of several previous research projects in this area have yielded a strong, flexible mandatory access control architecture called Flask. A reference implementation of this architecture was first integrated into a security-enhanced Linux® prototype system in order to demonstrate the value of flexible mandatory access controls and how such controls could be added to an operating system. The architecture has been subsequently mainstreamed into Linux and ported to several other systems, including the Solaris™ operating system, the FreeBSD® operating system, and the Darwin kernel, spawning a wide range of related work.
  • Then another boon for IBM. Experts at the German Federal Office for Security in Information Technology (BIS) determined that Windows 8 is dangerous for data security. It allows Microsoft to control the computer remotely through a “special surveillance chip,” the wonderfully named Trusted Platform Module (TPM), and a backdoor in the software – with keys likely accessible to the NSA and possibly other third parties, such as the Chinese. Risks: “Loss of control over the operating system and the hardware” [read.... LEAKED: German Government Warns Key Entities Not To Use Windows 8 – Links The NSA.

  • Among a slew of American companies who contributed to the NSA’s “mainstreaming” efforts: Red Hat. And IBM? Like just about all of our American tech heroes, it looks at the NSA and other agencies in the Intelligence Community as “the Customer” with deep pockets, ever increasing budgets, and a thirst for technology and data. Which brings us back to Windows 8 and TPM. A decade ago, a group was established to develop and promote Trusted Computing that governs how operating systems and the “special surveillance chip” TPM work together. And it too has been cooperating with the NSA. The founding members of this Trusted Computing Group, as it’s called facetiously: AMD, Cisco, Hewlett-Packard, Intel, Microsoft, and Wave Systems. Oh, I almost forgot ... and IBM. And so IBM might not escape, despite its protestations and slick sales presentations, the suspicion by foreign companies and governments alike that its Linux servers too have been compromised – like the cloud products of other American tech companies. And now, they’re going to pay a steep price for their cooperation with the NSA. Read...  NSA Pricked The “Cloud” Bubble For US Tech Companies

SVG Is The Future Of Application Development | SitePoint » - 0 views

  •  
    I could see this coming a mile away, ana it's about time! ".... So if HTML can't deliver for us here, what will? Microsoft wants us to use Silverlight and Adobe wants us to use Flash and AIR, of course. And Apple…? Apple ostensibly wants us to use HTML5's canvas. Both Microsoft's and Adobe's contenders are proprietary, which seems to be reason enough for web developers to avoid them to a certain degree, and all of them muddy HTML, which is a dangerous thing for the semantic web. But Apple actually has a trick up its sleeve. Like Mozilla's been doing with Firefox, Apple has quietly been implementing better support for SVG, the W3C's Recommendation for XML-based vector graphics, into WebKit. SVG delivers the same kind of vector graphics capabilities that Flash does, but it does so using all the interoperability benefits that XML brings along for the ride. SVG is great for graphically displaying both text and images, manipulating them with declarative visual primitives, and it comes with a host of lickable effects. Ironically, SVG was originally jointly developed by both Adobe and Sun Microsystems but recently it's Sun Labs that has been doing interesting stuff with the technology. The most compelling experiment of this kind has to be Sun Labs's Lively Kernel project....."

The Million Dollar Dissident: NSO Group's iPhone Zero-Days used against a UAE Human Rig... - 0 views

  • 1. Executive Summary Ahmed Mansoor is an internationally recognized human rights defender, based in the United Arab Emirates (UAE), and recipient of the Martin Ennals Award (sometimes referred to as a “Nobel Prize for human rights”).  On August 10 and 11, 2016, Mansoor received SMS text messages on his iPhone promising “new secrets” about detainees tortured in UAE jails if he clicked on an included link. Instead of clicking, Mansoor sent the messages to Citizen Lab researchers.  We recognized the links as belonging to an exploit infrastructure connected to NSO Group, an Israel-based “cyber war” company that sells Pegasus, a government-exclusive “lawful intercept” spyware product.  NSO Group is reportedly owned by an American venture capital firm, Francisco Partners Management. The ensuing investigation, a collaboration between researchers from Citizen Lab and from Lookout Security, determined that the links led to a chain of zero-day exploits (“zero-days”) that would have remotely jailbroken Mansoor’s stock iPhone 6 and installed sophisticated spyware.  We are calling this exploit chain Trident.  Once infected, Mansoor’s phone would have become a digital spy in his pocket, capable of employing his iPhone’s camera and microphone to snoop on activity in the vicinity of the device, recording his WhatsApp and Viber calls, logging messages sent in mobile chat apps, and tracking his movements.   We are not aware of any previous instance of an iPhone remote jailbreak used in the wild as part of a targeted attack campaign, making this a rare find.
  • The Trident Exploit Chain: CVE-2016-4657: Visiting a maliciously crafted website may lead to arbitrary code execution CVE-2016-4655: An application may be able to disclose kernel memory CVE-2016-4656: An application may be able to execute arbitrary code with kernel privileges Once we confirmed the presence of what appeared to be iOS zero-days, Citizen Lab and Lookout quickly initiated a responsible disclosure process by notifying Apple and sharing our findings. Apple responded promptly, and notified us that they would be addressing the vulnerabilities. We are releasing this report to coincide with the availability of the iOS 9.3.5 patch, which blocks the Trident exploit chain by closing the vulnerabilities that NSO Group appears to have exploited and sold to remotely compromise iPhones. Recent Citizen Lab research has shown that many state-sponsored spyware campaigns against civil society groups and human rights defenders use “just enough” technical sophistication, coupled with carefully planned deception. This case demonstrates that not all threats follow this pattern.  The iPhone has a well-deserved reputation for security.  As the iPhone platform is tightly controlled by Apple, technically sophisticated exploits are often required to enable the remote installation and operation of iPhone monitoring tools. These exploits are rare and expensive. Firms that specialize in acquiring zero-days often pay handsomely for iPhone exploits.  One such firm, Zerodium, acquired an exploit chain similar to the Trident for one million dollars in November 2015. The high cost of iPhone zero-days, the apparent use of NSO Group’s government-exclusive Pegasus product, and prior known targeting of Mansoor by the UAE government provide indicators that point to the UAE government as the likely operator behind the targeting. Remarkably, this case marks the third commercial “lawful intercept” spyware suite employed in attempts to compromise Mansoor.  In 2011, he was targeted with FinFisher’s FinSpy spyware, and in 2012 he was targeted with Hacking Team’s Remote Control System.  Both Hacking Team and FinFisher have been the object of several years of revelations highlighting the misuse of spyware to compromise civil society groups, journalists, and human rights workers.

Wikileaks Releases "NightSkies 1.2": Proof CIA Bugs "Factory Fresh" iPhones | Zero Hedge - 0 views

  • The latest leaks from WikiLeaks' Vault 7 is titled “Dark Matter” and claims that the CIA has been bugging “factory fresh” iPhones since at least 2008 through suppliers.
  • And here is the full press release from WikiLeaks: Today, March 23rd 2017, WikiLeaks releases Vault 7 "Dark Matter", which contains documentation for several CIA projects that infect Apple Mac Computer firmware (meaning the infection persists even if the operating system is re-installed) developed by the CIA's Embedded Development Branch (EDB). These documents explain the techniques used by CIA to gain 'persistence' on Apple Mac devices, including Macs and iPhones and demonstrate their use of EFI/UEFI and firmware malware.   Among others, these documents reveal the "Sonic Screwdriver" project which, as explained by the CIA, is a "mechanism for executing code on peripheral devices while a Mac laptop or desktop is booting" allowing an attacker to boot its attack software for example from a USB stick "even when a firmware password is enabled". The CIA's "Sonic Screwdriver" infector is stored on the modified firmware of an Apple Thunderbolt-to-Ethernet adapter.   "DarkSeaSkies" is "an implant that persists in the EFI firmware of an Apple MacBook Air computer" and consists of "DarkMatter", "SeaPea" and "NightSkies", respectively EFI, kernel-space and user-space implants.   Documents on the "Triton" MacOSX malware, its infector "Dark Mallet" and its EFI-persistent version "DerStake" are also included in this release. While the DerStake1.4 manual released today dates to 2013, other Vault 7 documents show that as of 2016 the CIA continues to rely on and update these systems and is working on the production of DerStarke2.0.   Also included in this release is the manual for the CIA's "NightSkies 1.2" a "beacon/loader/implant tool" for the Apple iPhone. Noteworthy is that NightSkies had reached 1.2 by 2008, and is expressly designed to be physically installed onto factory fresh iPhones. i.e the CIA has been infecting the iPhone supply chain of its targets since at least 2008.   While CIA assets are sometimes used to physically infect systems in the custody of a target it is likely that many CIA physical access attacks have infected the targeted organization's supply chain including by interdicting mail orders and other shipments (opening, infecting, and resending) leaving the United States or otherwise.

The Digital Hunt for Duqu, a Dangerous and Cunning U.S.-Israeli Spy Virus - The Intercept - 1 views

  • “Is this related to what we talked about before?” Bencsáth said, referring to a previous discussion they’d had about testing new services the company planned to offer customers. “No, something else,” Bartos said. “Can you come now? It’s important. But don’t tell anyone where you’re going.” Bencsáth wolfed down the rest of his lunch and told his colleagues in the lab that he had a “red alert” and had to go. “Don’t ask,” he said as he ran out the door. A while later, he was at Bartos’ office, where a triage team had been assembled to address the problem they wanted to discuss. “We think we’ve been hacked,” Bartos said.
  • They found a suspicious file on a developer’s machine that had been created late at night when no one was working. The file was encrypted and compressed so they had no idea what was inside, but they suspected it was data the attackers had copied from the machine and planned to retrieve later. A search of the company’s network found a few more machines that had been infected as well. The triage team felt confident they had contained the attack but wanted Bencsáth’s help determining how the intruders had broken in and what they were after. The company had all the right protections in place—firewalls, antivirus, intrusion-detection and -prevention systems—and still the attackers got in.
  • Bencsáth was a teacher, not a malware hunter, and had never done such forensic work before. At the CrySyS Lab, where he was one of four advisers working with a handful of grad students, he did academic research for the European Union and occasional hands-on consulting work for other clients, but the latter was mostly run-of-the-mill cleanup work—mopping up and restoring systems after random virus infections. He’d never investigated a targeted hack before, let alone one that was still live, and was thrilled to have the chance. The only catch was, he couldn’t tell anyone what he was doing. Bartos’ company depended on the trust of customers, and if word got out that the company had been hacked, they could lose clients. The triage team had taken mirror images of the infected hard drives, so they and Bencsáth spent the rest of the afternoon poring over the copies in search of anything suspicious. By the end of the day, they’d found what they were looking for—an “infostealer” string of code that was designed to record passwords and other keystrokes on infected machines, as well as steal documents and take screenshots. It also catalogued any devices or systems that were connected to the machines so the attackers could build a blueprint of the company’s network architecture. The malware didn’t immediately siphon the stolen data from infected machines but instead stored it in a temporary file, like the one the triage team had found. The file grew fatter each time the infostealer sucked up data, until at some point the attackers would reach out to the machine to retrieve it from a server in India that served as a command-and-control node for the malware.

  • Bencsáth took the mirror images and the company’s system logs with him, after they had been scrubbed of any sensitive customer data, and over the next few days scoured them for more malicious files, all the while being coy to his colleagues back at the lab about what he was doing. The triage team worked in parallel, and after several more days they had uncovered three additional suspicious files. When Bencsáth examined one of them—a kernel-mode driver, a program that helps the computer communicate with devices such as printers—his heart quickened. It was signed with a valid digital certificate from a company in Taiwan (digital certificates are documents ensuring that a piece of software is legitimate). Wait a minute, he thought. Stuxnet—the cyberweapon that was unleashed on Iran’s uranium-enrichment program—also used a driver that was signed with a certificate from a company in Taiwan. That one came from RealTek Semiconductor, but this certificate belonged to a different company, C-Media Electronics. The driver had been signed with the certificate in August 2009, around the same time Stuxnet had been unleashed on machines in Iran.
