2016 Saw A Massive Increase In Encrypted Web Traffic (eff.org) 91

EFF's "Deeplinks" blog has published nearly two dozen "2016 in Review" posts over the last nine days, one of which applauds 2016 as "a great year for adoption of HTTPS encryption for secure connections to websites." An anonymous reader writes: In 2016 most pages viewed on the web were encrypted. And over 21 million web sites obtained security certificates -- often for the first time -- through Let's Encrypt. But "a sizeable part of the growth in HTTPS came from very large hosting providers that decided to make HTTPS a default for sites that they host, including OVH, Wordpress.com, Shopify, Tumblr, Squarespace, and many others," EFF writes. Other factors included the support of Transport Layer Security (TLS) 1.3 by Firefox, Chrome, and Opera.

Destructive KillDisk Malware Turns Into Ransomware (securityweek.com) 56

wiredmikey writes from a report via SecurityWeek: A recently discovered variant of the KillDisk malware encrypts files and holds them for ransom instead of deleting them. Since KillDisk has been used in attacks aimed at industrial control systems (ICS), experts are concerned that threat actors may be bringing ransomware into the industrial domain. CyberX VP of research David Atch told SecurityWeek that the KillDisk variant they have analyzed is a well-written piece of ransomware, and victims are instructed to pay 222 bitcoins ($210,000) to recover their files, which experts believe suggests that the attackers are targeting "organizations with deep pockets." From the report: "The ransomware is designed to encrypt various types of files, including documents, databases, source code, disk images, emails and media files. Both local partitions and network folders are targeted. The contact email address provided to affected users is associated with Lelantos, a privacy-focused email provider only accessible through the Tor network. The Bitcoin address to which victims are told to send the ransom has so far not made any transactions. Atch pointed out that the same RSA public key is used for all samples, which means that a user who receives a decryptor will likely be able to decrypt files for all victims. According to CyberX, the malware requires elevated privileges and registers itself as a service. The threat terminates various processes, but it avoids critical system processes and ones associated with anti-malware applications, likely to avoid disrupting the system and triggering detection by security products."

US Congressional Committee Concludes Encryption Backdoors Won't Work (betanews.com) 98

"Any measure that weakens encryption works against the national interest," reports a bipartisan committee in the U.S. Congress. Mark Wilson quotes Beta News: The Congressional Encryption Working Group (EWG) was set up in the wake of the Apple vs FBI case in which the FBI wanted to gain access to the encrypted contents of a shooter's iPhone. The group has just published its end-of-year report summarizing months of meetings, analysis and debate. The report makes four key observations, starting off with: "Any measure that weakens encryption works against the national interest".

This is certainly not a new argument against encryption backdoors for the likes of the FBI, but it is an important one... The group says: "Congress should not weaken this vital technology... Cryptography experts and information security professionals believe that it is exceedingly difficult and impractical, if not impossible, to devise and implement a system that gives law enforcement exceptional access to encrypted data without also compromising security against hackers, industrial spies, and other malicious actors...

The report recommends that instead, Congress "should foster cooperation between the law enforcement community and technology companies," adding "there is already substantial cooperation between the private sector and law enforcement." [PDF] It also suggests that analyzing the metadata from "our digital 'footprints'...could play a role in filling in the gap. The technology community leverages this information every day to improve services and target advertisements. There appears to be an opportunity for law enforcement to better leverage this information in criminal investigations."

Russian Authorities Are Trying To Unlock iPhone 4S From Russian Ambassador's Killer (techcrunch.com) 106

The off-duty police officer who killed the Russian ambassador in Turkey was shot by Turkish special forces minutes after the crime. He had an iPhone 4S on him, and now, Haberturk, Turkish authorities asked for Russia's help to unlock the iPhone. From a report: Given that it's an iPhone 4S and it has a 4-digit passcode, it should be quite easy to unlock the device. There are many solutions out there to do this and authorities don't even need to ask for Apple's help. The iPhone 4S is quite old now and it was a much less secure device. First, the iPhone 4S runs iOS 5 to iOS 9, but many iPhone 4S owners didn't update to recent iOS versions. If the device runs iOS 7 or earlier, getting the content of the device is a piece of cake. The content of the device isn't encrypted as Apple started encrypting all data with iOS 8. Authorities can access this data quite easily. Second, if the iPhone is running iOS 8, remember that the iPhone 4S didn't have a Secure Enclave and Touch ID sensor. The Secure Enclave is a coprocessor that utilizes a secure boot process to make sure that it's uncompromized. It has a secret unique ID not accessible by the rest of the phone, Apple or anyone -- it's like a private key. The phone generates ephemeral keys (think public keys) to talk with the Secure Enclave. They only work with the unique ID to encrypt and decrypt the data on the coprocessor.

Leaked Files Reveal Scope of Cellebrite's Smartphone-Cracking Technology (zdnet.com) 37

An anonymous reader quotes a report from ZDNet: Earlier this year, we were sent a series of large, encrypted files purportedly belonging to a U.S. police department as a result of a leak at a law firm, which was insecurely synchronizing its backup systems across the internet without a password. Among the files was a series of phone dumps created by the police department with specialist equipment, which was created by Cellebrite, an Israeli firm that provides phone-cracking technology. We obtained a number of these so-called extraction reports. One of the more interesting reports by far was from an iPhone 5 running iOS 8. The phone's owner didn't use a passcode, meaning the phone was entirely unencrypted. The phone was plugged into a Cellebrite UFED device, which in this case was a dedicated computer in the police department. The police officer carried out a logical extraction, which downloads what's in the phone's memory at the time. (Motherboard has more on how Cellebrite's extraction process works.) In some cases, it also contained data the user had recently deleted. To our knowledge, there are a few sample reports out there floating on the web, but it's rare to see a real-world example of how much data can be siphoned off from a fairly modern device. We're publishing some snippets from the report, with sensitive or identifiable information redacted.

Encrypted Messaging App Signal Uses Google To Bypass Censorship (pcworld.com) 87

Developers of the popular Signal secure messaging app have started to use Google's domain as a front to hide traffic to their service and to sidestep blocking attempts. Bypassing online censorship in countries where internet access is controlled by the government can be very hard for users. It typically requires the use of virtual private networking (VPN) services or complex solutions like Tor, which can be banned too. From a report on PCWorld: Open Whisper Systems, the company that develops Signal -- a free, open-source app -- faced this problem recently when access to its service started being censored in Egypt and the United Arab Emirates. Some users reported that VPNs, Apple's FaceTime and other voice-over-IP apps were also being blocked. The solution from Signal's developers was to implement a censorship circumvention technique known as domain fronting that was described in a 2015 paper by researchers from University of California, Berkeley, the Brave New Software project and Psiphon. The technique involves sending requests to a "front domain" and using the HTTP Host header to trigger a redirect to a different domain. If done over HTTPS, such redirection would be invisible to someone monitoring the traffic, because the HTTP Host header is sent after the HTTPS connection is negotiated and is therefore part of the encrypted traffic.

NIST Asks Public For Help With Quantum-Proof Cryptography (securityledger.com) 138

chicksdaddy quotes a report from The Security Ledger: With functional, quantum computers on the (distant?) horizon, The National Institute of Standards and Technology (NIST) is asking the public for help heading off what it calls "a looming threat to information security:" powerful quantum computers capable of breaking even the strongest encryption codes used to protect the privacy of digital information. In a statement Tuesday, NIST asked the public to submit ideas for "post-quantum cryptography" algorithms that will be "less susceptible to a quantum computer's attack." NIST formally announced its quest in a publication on The Federal Register. Dustin Moody, a mathematician at NIST said the Institute's main focus is developing new public key cryptography algorithms, which are used today to protect both stored and transmitted information. "We're looking to replace three NIST cryptographic standards and guidelines that would be the most vulnerable to quantum computers," Moody said. They are FIPS 186-4, NIST SP 800-56A and NIST SP 800-56B. Researchers have until November, 2017 to submit their ideas. After the deadline, NIST will review the submissions. Proposals that meet the "post-quantum crypto" standards set up by NIST will be invited to present their algorithms at an open workshop in early 2018.

Egypt Has Blocked Encrypted Messaging App Signal (engadget.com) 44

An anonymous reader writes: Egypt has blocked its residents from accessing encrypted messaging app Signal, according to the application's developer. Mada Masr, an Egypt-based media organization, reported yesterday that several users took to Twitter over the weekend to report that they could no longer send or receive messages while on Egyptian IP addresses. Open Whisper Systems, the team behind the app, told a user asking about a situation that everything was working just as intended on their end. Now that the company has confirmed that the country is blocking access to Edward Snowden's preferred messaging app, it has begun working on a way to circumvent the ban. They intend to deploy their solution over the next few weeks.

Aircraft Entertainment Systems Hacks Are Back (threatpost.com) 56

Reader msm1267 writes: Researchers at IOActive today disclosed vulnerabilities in Panasonic Avionics In-Flight Entertainment Systems that were reported to the manufacturer close to two years ago. The flaws could be abused to manipulate in-flight data shown to passengers, or access personal information and credit card data swiped at the seat for premium entertainment or Internet access. Given that the firmware is customizable and used by dozens airlines in hundreds of aircraft models, the researchers said it's almost impossible to determine whether the vulnerabilities no longer exist across the board. IOActive said that segmentation between aircraft control and information services that oversee avionics and operational control of a plane should isolate these vulnerabilities to passenger entertainment domains. Whether an attacker could cross those domains and affect critical avionics systems would depend on specific devices and configurations, IOActive said, given that a physical path could exist that connects those systems through satellite communications terminals that provide in-flight updates to critical systems. The concern is that whether in some configurations, IFEs would share access to these devices and provide the physical path an attacker would need to reach critical systems. As for the vulnerabilities in passenger systems, IOActive said there is a lack of authentication and encryption between an on-board server and clients at passenger seats. This could allow an attacker on board to send commands to the IFE system to manipulate what's displayed to passengers, or read payment card data swiped at seats.

Google Releases Tool To Find Common Crypto Bugs (onthewire.io) 22

Trailrunner7 quotes a report from On the Wire: Google has released a new set of tests it uses to probe cryptographic libraries for vulnerabilities to known attacks. The tests can be used against most kinds of crypto algorithms and the company already has found 40 new weaknesses in existing algorithms. The tests are called Project Wycheproof, and Google's engineers designed them to help developers implement crypto libraries without having to become experts. Cryptographic libraries can be quite difficult to implement and making errors can lead to serious security problems. Attackers often will look for weak crypto implementations as a means of circumventing strong encryption in a target app. Among the issues that Google's engineers found with the Project Wycheproof tests is one in ECDH that allows an attacker to recover the private key in some circumstances. The bug is the result of some libraries not checking the elliptic curve points that they get from outside sources. "In cryptography, subtle mistakes can have catastrophic consequences, and mistakes in open source cryptographic software libraries repeat too often and remain undiscovered for too long. Good implementation guidelines, however, are hard to come by: understanding how to implement cryptography securely requires digesting decades' worth of academic literature. We recognize that software engineers fix and prevent bugs with unit testing, and we found that many cryptographic issues can be resolved by the same means," Daniel Bleichenbacher and Thai Duong, security engineers at Google, said in a post announcing the tool release. "Encodings of public keys typically contain the curve for the public key point. If such an encoding is used in the key exchange then it is important to check that the public and secret key used to compute the shared ECDH secret are using the same curve. Some libraries fail to do this check," Google's documentation says.

Evernote Reverses Course On Opt-out Privacy Policy That Would've Exposed Users' Content To Employees (venturebeat.com) 52

Evernote has withdrawn planned changes to its privacy policy that would have permitted some employees to view the content of users' note, as the company works on new features that rely on machine-learning technology. From a report on VentureBeat: The company caused an uproar earlier this week when news emerged of the pending changes, which were due to take effect on January 23. Even if users were to opt out of allowing their information to be viewed by employees, the planned changes drew attention to the company's existing policy that permitted employees to look at users' content "for other reasons stated in our Privacy Policy," which included quite a few vague reasons, including "to maintain and improve the service." Evernote CEO Chris O'Neill issued an apology of sorts yesterday for the company's "poor communication" around the policy, and pointed out that users' information would be anonymized. But today the company has gone one step further by announcing that it's no longer implementing the planned changes in their current form .

A $300 Device Can Steal Mac FileVault2 Passwords (bleepingcomputer.com) 88

An anonymous reader writes: Swedish hardware hacker Ulf Frisk has created a device that can extract Mac FileVault2 (Apple's disk encryption utility) passwords from a device's memory before macOS boots and anti-DMA protections kick in. The extracted passwords are in cleartext, and they also double as the macOS logon passwords. The attack requires physical access, but it takes less than 30 seconds to carry out. A special device is needed, which runs custom software (available on GitHub), and uses hardware parts that cost around $300. Apple fixed the attack in macOS 10.12.2. The device is similar to what Samy Kamker created with Poison Tap.

Malvertising Campaign Infects Your Router Instead of Your Browser (bleepingcomputer.com) 137

An anonymous reader quotes a report from BleepingComputer: Malicious ads are serving exploit code to infect routers, instead of browsers, in order to insert ads in every site users are visiting. Unlike previous malvertising campaigns that targeted users of old Flash or Internet Explorer versions, this campaign focused on Chrome users, on both desktop and mobile devices. The malicious ads included in this malvertising campaign contain exploit code for 166 router models, which allow attackers to take over the device and insert ads on websites that didn't feature ads, or replace original ads with the attackers' own. Researchers haven't yet managed to determine an exact list of affected router models, but some of the brands targeted by the attackers include Linksys, Netgear, D-Link, Comtrend, Pirelli, and Zyxel. Because the attack is carried out via the user's browser, using strong router passwords or disabling the administration interface is not enough. The only way users can stay safe is if they update their router's firmware to the most recent versions, which most likely includes protection against the vulnerabilities used by this campaign. The "campaign" is called DNSChanger EK and works when attackers buy ads on legitimate websites and insert malicious JavaScript in these ads, "which use a WebRTC request to a Mozilla STUN server to determine the user's local IP address," according to BleepingComputer. "Based on this local IP address, the malicious code can determine if the user is on a local network managed by a small home router, and continue the attack. If this check fails, the attackers just show a random legitimate ad and move on. For the victims the crooks deem valuable, the attack chain continues. These users receive a tainted ad which redirects them to the DNSChanger EK home, where the actual exploitation begins. The next step is for the attackers to send an image file to the user's browser, which contains an AES (encryption algorithm) key embedded inside the photo using the technique of steganography. The malicious ad uses this AES key to decrypt further traffic it receives from the DNSChanger exploit kit. Crooks encrypt their operations to avoid the prying eyes of security researchers."

150 Filmmakers and Photojournalists Call On Nikon, Sony, and Canon To Build in Encryption (zdnet.com) 229

Some of the world's leading photojournalists and filmmakers are calling on the manufacturers of the cameras they use to add encryption to their products, as the number of threats they face from having their devices seized is "literally too high to count." From a ZDNet report: Over 150 documentary makers and reporters signed an open letter by the Freedom of the Press Foundation, asking for camera makers -- including Nikon, Sony, and Canon -- to ensure that their work is protected while often "attempting to uncover wrongdoing in the interests of justice." "Documentary filmmakers and photojournalists work in some of the most dangerous parts of the world, often risking their lives to get footage of newsworthy events to the public," said Trevor Timm, the foundation's executive director. But, he said, "they face a variety of threats from border security guards, local police, intelligence agents, terrorists, and criminals when attempting to safely return their footage so that it can be edited and published." The filmmakers say that camera security has lagged behind the rest of the industry, leaving their work "dangerously vulnerable."

HP Shutting Down Default FTP, Telnet Access To Network Printers (pcworld.com) 83

Security experts consider the aging FTP and Telnet protocols unsafe, and HP has decided to clamp down on access to networked printers through the remote-access tools. From a report on PCWorld: Some of HP's new business printers will, by default, be closed to remote access via protocols like FTP and Telnet. However, customers can activate remote printing access through those protocols if needed. "HP has started the process of closing older, less-maintained interfaces including ports, protocols and cipher suites" identified by the U.S. National Institute of Standards and Technology as less than secure, the company said in a statement. In addition, HP also announced firmware updates to existing business printers with improved password and encryption settings, so hackers can't easily break into the devices.

China's New 'Social Credit Score' Law Means Full Access To Customer Data (insurancejournal.com) 83

AnonymousCube shares this quote about China's new 'Social Credit Score' law from an insurance industry magazine: "Companies are also required to give government investigators complete access to their data if there is suspected wrong-doing, and Internet operators must cooperate in any national security or crime-related investigation."

Note that China has an extremely flexible definition of "national security". Additionally computer equipment will need to undergo mandatory certification, that could involve giving up source code, encryption keys, or even proprietary intellectual data, as Microsoft has been doing for some time.

The article suggests businesses like insurers "will likely see the cost of complying with this new action as a disincentive to conducting business in China."

Encryption Backdoor Sneaks Into UK Law (theregister.co.uk) 137

Coisiche found a disturbing article from The Register about the U.K.'s new "Snoopers' Charter" law that has implications for tech companies around the world: Among the many unpleasant things in the Investigatory Powers Act that was officially signed into law this week, one that has not gained as much attention is the apparent ability for the U.K. government to undermine encryption and demand surveillance backdoors... As per the final wording of the law, comms providers on the receiving end of a "technical capacity notice" will be obliged to do various things on demand for government snoops -- such as disclosing details of any system upgrades and removing "electronic protection" on encrypted communications. Thus, by "technical capability," the government really means backdoors and deliberate security weaknesses so citizens' encrypted online activities can be intercepted, deciphered and monitored... At the end of the day, will the U.K. security services be able to read your email, your messages, your posts and private tweets, and your communications if they believe you pose a threat to national security? Yes, they will.
The bill added the Secretaries of State as a required signatory to the "technical capacity" notices, which "introduces a minor choke-point and a degree of accountability." But the article argues the law ultimately anticipates the breaking of encryption, and without customer notification. "The U.K. government can certainly insist that a company not based in the U.K. carry out its orders -- that situation is specifically included in the new law -- but as to whether it can realistically impose such a requirement, well, that will come down to how far those companies are willing to push back and how much they are willing to walk away from the U.K. market."

Mozilla Puts New Money To Use Fighting For 'Internet Health' (cnet.com) 110

Stephen Shankland, writing for CNET: Mozilla is marshaling public support for political positions, like backing net neutrality, defending encryption and keeping government surveillance from getting out of hand, says Denelle Dixon-Thayer, Mozilla's chief legal and business officer. The organization is funding the efforts with revenue from Firefox searches, which has jumped since 2014 when it switched from a global deal with Google to a set of regional deals. Mozilla brought in $421 million in revenue last year largely through partnerships with Yahoo in the US, Yandex in Russia and Baidu in China, according to tax documents released alongside Mozilla's 2015 annual report on Thursday. Pushing policy work brings new challenges well beyond traditional Mozilla work competing against Google's Chrome browser and Microsoft's Internet Explorer. They include squaring off against the incoming administration of Donald Trump.

Holding Shift + F10 During Windows 10 Updates Opens Root CLI, Bypasses BitLocker (bleepingcomputer.com) 138

An anonymous reader quotes a report from BleepingComputer: Windows security expert and infrastructure trainer Sami Laiho says that by holding SHIFT + F10 while a Windows 10 computer is installing a new OS build, an attacker can open a command-line interface with SYSTEM privileges. This CLI debugging interface also grants the attacker full access to the computer's hard drive data, despite the presence of BitLocker. The CLI debugging interface is present when updating to new Windows 10 and Windows 10 Insiders builds. The most obvious exploitation scenario is when a user leaves his computer unattended during the update procedure. A malicious insider can open the CLI debugger and perform malicious operations under a root user, despite BitLocker's presence. But there are other scenarios where Laiho's SHIFT + F10 trick can come in handy. For example when police have seized computers from users who deployed BitLocker or when someone steals your laptop. Windows 10 defaults help police/thieves in this case because these defaults forcibly update computers, even if the user hasn't logged on for weeks or months. This CLI debugging interface grants the attacker full access to the computer's hard drive, despite the presence of BitLocker. The reason is that during the Windows 10 update procedure, the OS disables BitLocker while the Windows PE (Preinstallation Environment) installs a new image of the main Windows 10 operating system. "This [update procedure] has a feature for troubleshooting that allows you to press SHIFT + F10 to get a Command Prompt," Laiho writes on his blog. "The real issue here is the Elevation of Privilege that takes a non-admin to SYSTEM (the root of Windows) even on a BitLocker (Microsoft's hard disk encryption) protected machine." Laiho informed Microsoft of the issue and the company is apparently working on a fix.
