Wi-Fi Alliance Launches WPA3 Security Standard (securityweek.com) 97

wiredmikey writes: The Wi-Fi Alliance, the organization responsible for maintaining Wi-Fi technology, announced the launch of the WPA3 security standard. The latest version of the Wi-Fi Protected Access (WPA) protocol brings significant improvements in terms of authentication and data protection.

WPA3 has two modes of operation: Personal and Enterprise. WPA3-Personal's key features include enhanced protection against offline dictionary attacks and password guessing attempts. WPA3-Enterprise provides 192-bit encryption for extra security, improved network resiliency, and greater consistency when it comes to the deployment of cryptographic tools.

OpenBSD Chief De Raadt Says No Easy Fix For New Intel CPU Bug 'TLBleed' (itwire.com) 123

Recompiling is unlikely to be a catch-all solution for a recently unveiled Intel CPU vulnerability known as TLBleed, the details of which were leaked on Friday, the head of the OpenBSD project Theo de Raadt says. iTWire reports: The details of TLBleed, which gets its name from the fact that the flaw targets the translation lookaside buffer, a CPU cache, were leaked to the British tech site, The Register; the side-channel vulnerability can be theoretically exploited to extract encryption keys and private information from programs. Former NSA hacker Jake Williams said on Twitter that a fix would probably need changes to the core operating system and were likely to involve "a ton of work to mitigate (mostly app recompile)." But de Raadt was not so sanguine. "There are people saying you can change the kernel's process scheduler," he told iTWire on Monday. "(It's) not so easy."

He said that Williams was lacking all the details and not thinking it through. "They actually have sufficient detail to think it through: the article says the TLB is shared between hyperthreading CPUs, and it is unsafe to share between two different contexts. Basically you can measure evictions against your own mappings, which indicates the other process is touching memory (you can determine the aliasing factors)."
De Raadt said he was still not prepared to say more, saying: "Please wait for the paper [which is due in August]."

EFF Announces STARTTLS Everywhere To Help Make Email Delivery More Secure (betanews.com) 58

Mark Wilson writes: When it comes to messaging tools, people have started to show greater interest in whether encryption is used for security, and the same for websites -- but not so much with email. Thanks to the work of the Electronic Frontier Foundation, however, email security is being placed at the top of the agenda. The privacy group today announces STARTTLS Everywhere, its new initiative to improve the security of the email ecosystem. STARTTLS is an addition to SMTP, and while it does not add end-to-end encryption, it does provide hop-to-hop encryption, which is very much a step in the right direction. In a blog post, EFF elaborates SMARTTLS for the uninitiated, and outlines how it worked around some of the tech's underlying challenges: There are two primary security models for email transmission: end-to-end, and hop-to-hop. Solutions like PGP and S/MIME were developed as end-to-end solutions for encrypted email, which ensure that only the intended recipient can decrypt and read a particular message. Unlike PGP and S/MIME, STARTTLS provides hop-to-hop encryption (TLS for email), not end-to-end. Without requiring configuration on the end-user's part, a mailserver with STARTTLS support can protect email from passive network eavesdroppers. For instance, network observers gobbling up worldwide information from Internet backbone access points (like the NSA or other governments) won't be able to see the contents of messages, and will need more targeted, low-volume methods. In addition, if you are using PGP or S/MIME to encrypt your emails, STARTTLS prevents metadata leakage (like the "Subject" line, which is often not encrypted by either standard) and can negotiate forward secrecy for your emails.

Apple Refutes Hacker's Claim He Could Break iPhone Passcode Limit (cnet.com) 96

A security researcher claimed he had figured out a way to bypass the passcode lock limit on an iPhone or iPad, ZDNet reported. But it turned out the passcodes he tested weren't always counted. From a report: "The recent report about a passcode bypass on iPhone was in error, and a result of incorrect testing," Apple said Saturday in an emailed statement. Since the 2014 release of iOS 8, all iPhones and iPads have come with device encryption protected by a four- or six-digit passcode. If the wrong passcode is entered too many times, the device gets wiped, explained ZDNet's Zack Whittaker. But Hacker House co-founder Matthew Hickey figured out a way "to bypass the 10-time limit and enter as many codes as he wants -- even on iOS 11.3," Whittaker wrote.

Linux 4.18 Preparing Many New Features While Dropping 100k+ Lines of Code (phoronix.com) 105

An anonymous reader writes: Linux 4.18 development is going strong with recent 4.18-rc1 release. This kernel cycle has dropped 107,210 lines of code so far but Linux 4.18 is adding many new features. The kernel is coming in lighter as a result of the LustreFS code being removed and other code cleanups. On the feature front, Phoronix reports, "ew AMDGPU support improvements, mainlining of the V3D DRM driver, initial open-source work on NVIDIA Volta GV100 hardware, merging of the Valve Steam Controller kernel driver, merging of the BPFILTER framework, ARM Spectre mitigation work, Speck file-system encryption support, removal of the Lustre file-system, the exciting restartable sequences system call was merged, the new DM writecache target, and much more."

Another Day, Another Intel CPU Security Hole: Lazy State (zdnet.com) 110

Steven J. Vaughan-Nichols, writing for ZDNet: The latest Intel revelation, Lazy FP state restore, can theoretically pull data from your programs, including encryption software, from your computer regardless of your operating system. Like its forebears, this is a speculative execution vulnerability. In an interview, Red Hat Computer Architect Jon Masters explained: "It affects Intel designs similar to variant 3-a of the previous stuff, but it's NOT Meltdown." Still, "it allows the floating point registers to be leaked from another process, but alas that means the same registers as used for crypto, etc." Lazy State does not affect AMD processors.

This vulnerability exists because modern CPUs include many registers (internal memory) that represent the state of each running application. Saving and restoring this state when switching from one application to another takes time. As a performance optimization, this may be done "lazily" (i.e., when needed) and that is where the problem hides. This vulnerability exploits "lazy state restore" by allowing an attacker to obtain information about the activity of other applications, including encryption operations.

Digital IDs Needed To End 'Mob Rule' Online, Says UK's Security Minister (independent.co.uk) 517

Digital IDs should be brought in to end online anonymity that permits "mob rule" and lawlessness online, the security minister of United Kingdom has said. From a report: Ben Wallace said authentication used by banks could also by employed by internet firms to crack down on bullying and grooming, as he warned that people had to make a choice between "the wild west or a civilised society" online. He also took aim at the "phoniness" of Silicon Valley billionaires, and called for companies such as WhatsApp to contribute to society over the negative costs of their technology, such as end-to-end encryption. It comes after Theresa May took another step against tech giants, saying they would be ordered to clamp down on vile attacks against women on their platforms. The prime minister will target firms such as Facebook and Twitter as she makes the pitch at the G7 summit this weekend, where she will urge social media firms to treat violent misogyny with the same urgency as they do terror threats. Mr Wallace told The Times: "A lot of the bullying on social media and the grooming is because those people know you cannot identify them. It is mob rule on the internet. You shouldn't be able to hide behind anonymity."

Russia Demands Apple Remove Telegram From Russian App Store (macrumors.com) 113

The Russian government is asking Apple to help it block Telegram by removing it from the country's App Store. Mac Rumors reports: A Russian court in April ordered carriers and internet providers in the country to block Telegram back in April, after Telegram refused to provide Russia with backdoor access to user messages. Despite issuing the block order back in April, Russia has only been able to disrupt Telegram's operations in the country by 15 to 30 percent. Given the government's inability to block the app, Roskomnadzor, the division of the government that controls media and telecommunications, has demanded that Apple remove the Telegram app from the Russian App Store. The group first asked Apple to remove the app in April, but is appealing to Apple again.

"In order to avoid possible action by Roskomnadzor for violations of the functioning of the above-mentioned Apple Inc. service, we ask you to inform us as soon as possible about your company's further actions to resolve the problematic issue," the regulator wrote. Roskomnadzor has given Apple one month to remove the Telegram app from the App Store. Roskomnadzor's director Alexander Zharov said he did not want to "forecast further actions" should Apple not comply with the request following the 30 day period.

How WIRED lost $100,000 in Bitcoin (wired.com) 127

An anonymous reader writes: Back in 2013, the halcyon days of at-home Bitcoin mining, staffers in the WIRED San Francisco office turned on one of Butterfly Labs' mining machines and let it whir away, amassing a horde of 13 bitcoins -- now worth $100,000. But today we have nothing to show for our efforts. What happened to our loot?

The same thing that has happened to millions of other unfortunate miners, actually: We lost our private key, a 64-digit string of random numbers that not one of us remembers. And we've got basically no chance of recovering it: "Originally I was going to say that the closest metaphor I have is that we dropped a car key somewhere in the Atlantic," says Stefan Antonowicz, WIRED's then-head of engineering. "But I think it's closer for me to say we dropped the key somewhere between here and the Alpha Centauri."

Researchers Crack Open AMD's Server VM Encryption (theregister.co.uk) 50

Shaun Nichols, reporting for The Register: A group of German researchers have devised a method to thwart the VM security in AMD's server chips. Dubbed SEVered (PDF), the attack would potentially allow an attacker, or malicious admin who had access to the hypervisor, the ability to bypass AMD's Secure Encrypted Virtualization (SEV) protections.

The problem, say Fraunhofer AISEC researchers Mathias Morbitzer, Manuel Huber, Julian Horsch and Sascha Wessel, is that SEV, which is designed to isolate VMs from the prying eyes of the hypervisor, doesn't fully isolate and encrypt the VM data within the physical memory itself.

In Apple Mail, There's No Protecting PGP-Encrypted Messages (theintercept.com) 25

It has been nearly two weeks since researchers unveiled "EFAIL," a set of critical software vulnerabilities that allow encrypted email messages to be stolen from within the inbox. The Intercept reports that developers of email clients and encryption plugins are still scrambling to come up with a permanent fix. From the report: Apple Mail is the email client that comes free with every Mac computer, and an open source project called GPGTools allows Apple Mail to smoothly encrypt and decrypt messages using the 23-year-old PGP standard. The day the EFAIL paper was published, GPGTools instructed users to workaround EFAIL by changing a setting in Apple Mail to disable loading remote content. Similarly, the creator of PGP, Phil Zimmermann, co-signed a blog post Thursday stating that EFAIL was "easy to mitigate" by disabling the loading of remote content in GPGTools. But even if you follow this advice and disable remote content, Apple Mail and GPGTools are still vulnerable to EFAIL.

I developed a proof-of-concept exploit that works against Apple Mail and GPGTools even when remote content loading is disabled (German security researcher Hanno Bock also deserves much of the credit for this exploit, more on that below). I have reported the vulnerability to the GPGTools developers, and they are actively working on an update that they plan on releasing soon.

FBI Repeatedly Overstated Encryption Threat Figures To Congress, Public (techcrunch.com) 160

mi shares a report from The Washington Post (Warning: source may be paywalled; alternative source): The FBI has repeatedly provided grossly inflated statistics to Congress and the public about the extent of problems posed by encrypted cellphones, claiming investigators were locked out of nearly 7,800 devices connected to crimes last year when the correct number was much smaller, probably between 1,000 and 2,000.

Over a period of seven months, FBI Director Christopher A. Wray cited the inflated figure as the most compelling evidence for the need to address what the FBI calls "Going Dark" -- the spread of encrypted software that can block investigators' access to digital data even with a court order. "The FBI's initial assessment is that programming errors resulted in significant over-counting of mobile devices reported,'' the FBI said in a statement Tuesday. The bureau said the problem stemmed from the use of three distinct databases that led to repeated counting of phones. Tests of the methodology conducted in April 2016 failed to detect the flaw, according to people familiar with the work.

IBM Warns Quantum Computing Will Break Encryption (zdnet.com) 197

Long-time Slashdot reader CrtxReavr shares a report from ZDNet: Quantum computers will be able to instantly break the encryption of sensitive data protected by today's strongest security, warns the head of IBM Research. This could happen in a little more than five years because of advances in quantum computer technologies. "Anyone that wants to make sure that their data is protected for longer than 10 years should move to alternate forms of encryption now," said Arvind Krishna, director of IBM Research... Quantum computers can solve some types of problems near-instantaneously compared with billions of years of processing using conventional computers... Advances in novel materials and in low-temperature physics have led to many breakthroughs in the quantum computing field in recent years, and large commercial quantum computer systems will soon be viable and available within five years...

In addition to solving tough computing problems, quantum computers could save huge amounts of energy, as server farms proliferate and applications such as bitcoin grow in their compute needs. Each computation takes just a few watts, yet it could take several server farms to accomplish if it were run on conventional systems.

The original submission raises another possibility. "What I wonder is, if encryption can be 'instantly broken,' does this also mean that remaining crypto-coins can be instantly discovered?"

Encrypted Email Has a Major, Divisive Flaw (wired.com) 116

An anonymous reader quotes a report from Wired: The ubiquitous email encryption schemes PGP and S/MIME are vulnerable to attack, according to a group of German and Belgian researchers who posted their findings on Monday. The weakness could allow a hacker to expose plaintext versions of encrypted messages -- a nightmare scenario for users who rely on encrypted email to protect their privacy, security, and safety. The weakness, dubbed eFail, emerges when an attacker who has already managed to intercept your encrypted emails manipulates how the message will process its HTML elements, like images and multimedia styling. When the recipient gets the altered message and their email client -- like Outlook or Apple Mail -- decrypts it, the email program will also load the external multimedia components through the maliciously altered channel, allowing the attacker to grab the plaintext of the message.

The eFail attack requires hackers to have a high level of access in the first place that, in itself, is difficult to achieve. They need to already be able to intercept encrypted messages, before they begin waylaying messages to alter them. PGP is a classic end-to-end encryption scheme that has been a go-to for secure consumer email since the late 1990s because of the free, open-source standard known as OpenPGP. But the whole point of doing the extra work to keep data encrypted from the time it leaves the sender to the time it displays for the receiver is to reduce the risk of access attacks -- even if someone can tap into your encrypted messages, the data will still be unreadable. eFail is an example of these secondary protections failing.

AMD Integrates Ryzen PRO and Radeon Vega Graphics In Next-Gen APUs (zdnet.com) 76

The three biggest PC OEMs -- Dell, HP, and Lenovo -- are now offering AMD Ryzen PRO mobile and desktop accelerated processing units (APUs) with built-in Radeon Vega graphics in a variety of commercial systems. There are a total of seven new APUs -- three for the mobile space and four for the desktop. As AMD notes in its press release, the first desktops to ship with these latest chips include: the HP Elitedesk G4 and 285 Desktop, the Lenovo ThinkCentre M715, and the Dell Optiplex 5055. ZDNet's Adrian Kingsley-Hughes writes about what makes Ryzen PRO so appealing: Ryzen PRO has been built from the ground up to focus on three pillars -- power, security and reliability. Built-in security means integrated GuardMI technology, an AES 128-bit encryption engine, Windows 10 Enterprise Security support, and support for fTPM/TPM 2.0 Trusted Platform Module. One of the features of Ryzen PRO that AMD hopes will appeal to commercial users is the enterprise-grade reliability that the chips come backed with, everything from 18-moths of planned software availability, 24-months processor availability, a commercial-grade QA process, 36-moth warranty, and enterprise-class manageability.

There are no worries on the performance front either, with the Ryzen PRO with Vega Graphics being the world's fastest processor currently available for ultrathin commercial notebooks, with the AMD Ryzen 7 PRO 2700U offering up to 22 percent more productivity performance than Intel's 8th-generation Core i7-8550U in testing carried out by AMD. AMD has also designed the Ryzen PRO processors to be energy-efficient, enabling up to 16 hours of battery life in devices, or 10.5 hours of video playback. The Ryzen PRO with Vega Graphics desktop processors are also no slouches, opening up a significant performance gap when compared to Intel Core i5 8400 and Core i3 8100 parts.
AMD also announced that it is sampling its second-generation Threadripper 2900X, 2920X and 2950X products. "For Threadripper Gen2 you can expect a refresh of the current line-up; an 8-core Threadripper 2900X, a 12-core Threadripper 2920X and of course a 16-core Threadripper 2950X," reports Guru3D.com. "AMD will apply the same Zen+ tweaks to the processors; including memory latency optimizations and higher clock speeds."

AMD has something for the datacenter enthusiasts out there too. Epyc, AMD's x86 server processor line based on the company's Zen microarchitecture, has a new promo video, claiming more performance, more security features, and more value than Intel Xeon. The company plans to market Epyc in an aggressive head-to-head format similar to how T-Mobile campaigns against Verizon and AT&T. Given Intel Xeon's 99% market share, they sort of have to...

Lawmakers Move To Block Government From Ordering Digital 'Back Doors' (thehill.com) 87

A bipartisan group of House lawmakers have introduced legislation that would block the federal government from requiring technology companies to design devices with so-called "back doors" to allow law enforcement to access them. From a report: The bill represents the latest effort by lawmakers in Congress to wade into the battle between federal law enforcement officials and tech companies over encryption, which reached a boiling point in 2015 as the FBI tussled with Apple over a locked iPhone linked to the San Bernardino terror attack case.

Top FBI and Justice Department officials have repeatedly complained that they have been unable to access devices for ongoing criminal investigations because of encryption. FBI Director Christopher Wray has suggested that devices could be designed to allow investigators to access them, though he insists the bureau is not looking for a "back door." The bipartisan bill introduced Thursday would prohibit federal agencies from requiring or requesting that firms "design or alter the security functions in its product or service to allow the surveillance of any user of such product or service, or to allow the physical search of such product" by the government.

Tech Giants Hit by NSA Spying Slam Encryption Backdoors (zdnet.com) 129

A coalition of Silicon Valley tech giants has doubled down on its criticism of encryption backdoors following a proposal that would give law enforcement access to locked and encrypted devices. From a report: The group, which focuses on efforts to reform government surveillance, said in a statement that it continues to advocate for strong encryption, and decried attempts to undermine the technology. "Recent reports have described new proposals to engineer vulnerabilities into devices and services -- but they appear to suffer from the same technical and design concerns that security researchers have identified for years," the statement read. The renewed criticism follows a lengthy Wired article, in which former Microsoft software chief Ray Ozzie proposed a new spin on key escrow. Device encryption has hampered police investigations, and law enforcement officials have pushed tech companies to fix the problem -- even by way of suing them.

GitHub Accidentally Exposes Some Plaintext Passwords In Its Internal Logs (zdnet.com) 151

GitHub has sent an email to some of its 27 million users alerting them of a bug that exposed some user passwords in plaintext. "During the course of regular auditing, GitHub discovered that a recently introduced bug exposed a small number of users' passwords to our internal logging system," said the email. "We have corrected this, but you'll need to reset your password to regain access to your account." ZDNet reports: The email said that a handful of GitHub staff could have seen those passwords -- and that it's "unlikely" that any GitHub staff accessed the site's internal logs. It's unclear exactly how this bug occurred. GitHub's explanation was that it stores user passwords with bcrypt, a stronger password hashing algorithm, but that the bug "resulted in our secure internal logs recording plaintext user passwords when users initiated a password reset." "Rest assured, these passwords were not accessible to the public or other GitHub users at any time," the email said. GitHub said it "has not been hacked or compromised in any way."

Amazon Tells Signal's Creators To Stop Using Anti-Censorship Tool (theverge.com) 99

An anonymous reader quotes a report from The Verge: The team behind secure messaging app Signal says Amazon has threatened to kick the app off its CloudFront web service unless Signal drops the anti-censorship practice known as domain-fronting. Google recently banned the practice, which lets developers disguise web traffic to look like it's coming from a different source, allowing apps like Signal to evade country-level bans. As a result, Signal moved from Google to the Amazon-owned Souq content delivery network. But Amazon implemented its own ban on Friday. In an email that Moxie Marlinspike -- founder of Signal developer Open Whisper Systems -- posted today, Amazon orders the organization to immediately stop using domain-fronting or find another web services provider. Signal used the system to provide service in Egypt, Oman, and the United Arab Emirates (UAE), where it's officially banned. It got around filters by making traffic appear to come from a huge platform, since countries weren't willing to ban the entirety of a site like Google to shut down Signal. "The idea behind domain fronting was that to block a single site, you'd have to block the rest of the internet as well. In the end, the rest of the internet didn't like that plan," Marlinspike writes. "We are considering ideas for a more robust system, but these ecosystem changes have happened very suddenly. [...] In the meantime, the censors in these countries will have (at least temporarily) achieved their goals. Sadly, they didn't have to do anything but wait."

WhatsApp Founder Plans To Leave After Broad Clashes With Parent Facebook (washingtonpost.com) 29

Elizabeth Dwoskin, reporting for Washington Post: The billionaire chief executive of WhatsApp, Jan Koum, is planning to leave the company after clashing with its parent, Facebook, over the popular messaging service's strategy and Facebook's attempts to use its personal data and weaken its encryption, according to people familiar with internal discussions. Koum, who sold WhatsApp to Facebook for more than $19 billion in 2014, also plans to step down from Facebook's board of directors, according to these people. The date of his departure isn't known. He has been informing senior executives at Facebook and WhatsApp of his decision, and in recent months has been showing up less frequently to WhatsApp's offices on Facebook's campus in Silicon Valley, according to the people. The independence and protection of its users' data is a core tenet of WhatsApp that Koum and his co-founder, Brian Acton, promised to preserve when they sold their tiny startup to Facebook. It doubled down on its pledge by adding encryption in 2016. The data clash took on additional significance in the wake of revelations in March that Facebook had allowed third parties to mishandle its users' personal information. The move comes weeks after Brian Acton, the other co-founder of WhatsApp, urged people to delete their Facebook accounts.
