Academics Steal Data From Air-Gapped Systems Via a Keyboard's LEDs
by Peter Reutemann 11 Jul '19

11 Jul '19

'The Caps Lock, Num Lock, and Scroll Lock LEDs on a keyboard can be used to exfiltrate data from a secure air-gapped system, academics from an Israeli university have proved. From a report: The attack, which they named CTRL-ALT-LED, is nothing that regular users should worry about but is a danger for highly secure environments such as government networks that store top-secret documents or enterprise networks dedicated to storing non-public proprietary information. he attack requires some pre-requisites, such as the malicious actor finding a way to infect an air-gapped system with malware beforehand. CTRL-ALT-LED is only an exfiltration method. But once these prerequisites are met, the malware running on a system can make the LEDs of an USB-connected keyboard blink at rapid speeds, using a custom transmission protocol and modulation scheme to encode the transmitted data. A nearby attacker can record these tiny light flickers, which they can decode at a later point, using the same modulation scheme used to encode it.' -- source: https://it.slashdot.org/story/19/07/10/1836232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Samba 4.11 Removes SMB1 File-Sharing Protocol Version By Default
by Peter Reutemann 11 Jul '19

11 Jul '19

'Samba says version 4.11.0 will switch off previously on-by-default support for the aging and easily subverted SMB1 protocol. Slashdot reader Jeremy Allison - Sam shares a report from The Register detailing the new changes: The open-source SMB toolkit's developers say the Samba 4.11 build, currently in preview, will by default set SMB2_02 as the earliest supported version of the Windows file-sharing protocol. Admins will still have the option to allow SMB1 on their servers if they so choose, but support will be turned off by default. The move by Samba to drop SMB1 can be seen as long overdue, given that Microsoft has been moving to get rid of the file-server protocol version from its operating systems for several years now, even before it was revealed to be one of the NSA's favorite weak points to exploit.

Google Contractors Are Secretly Listening To Your Assistant Recordings
by Peter Reutemann 11 Jul '19

11 Jul '19

'A new report from Belgian broadcaster VRT News describes the process by which Google Home recordings end up being listened to by contractors -- and the scary part is that it apparently doesn't take much, if anything, to start a recording. While the recordings are not listened to live, audio clips are sent to subcontractors. The Next Web reports: VRT, with the help of a whistleblower, was able to listen to some of these clips and subsequently heard enough to discern the addresses of several Dutch and Belgian people using Google Home -- in spite of the fact some hadn't even uttered the words "Hey Google," which are supposed to be the device's listening trigger. The person who leaked the recordings was working as a subcontractor to Google, transcribing the audio files for subsequent use in improving its speech recognition. They got in touch with VRT after reading about Amazon Alexa keeping recordings indefinitely. According to the whistleblower, the recordings presented to them are meant to be carefully annotated, with notes included about the speakers presumed identity and age. From the sound of the report, these transcribers have heard just about everything. Personal information? Bedroom activities? Domestic violence? Yes, yes, and yes. While VRT only listened to recordings from Dutch and Belgian users, the platform the whistleblower showed them had recordings from all over the world -- which means there are probably thousands of other contractors listening to Assistant recordings. The VRT report states that the Google Home Terms of Service don't mention that recordings might be listened to by other humans. The report says that the recordings are identified by numbers rather than user names, but VRT "was able to pick up enough data from the recordings to find the addresses of the users in question, and even confront some of the users in the recordings -- to their great dismay," reports The Next Web. What does Google have to say about all this? That they only transcribe and use "about 0.2% of all audio clips" to improve their voice recognition technology.' -- source: https://yro.slashdot.org/story/19/07/10/2153210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Internet group brands Mozilla ‘internet villain’ for supporting DNS privacy feature
by Peter Reutemann 10 Jul '19

'An industry group of internet service providers has branded Firefox browser maker Mozilla an “internet villain” for supporting a DNS security standard. The U.K.’s Internet Services Providers’ Association (ISPA), the trade group for U.K. internet service providers, nominated the browser maker for its proposed effort to roll out the security feature, which they say will allow users to “bypass UK filtering obligations and parental controls, undermining internet safety standards in the UK.” Mozilla said late last year it was planning to test DNS-over-HTTPS to a small number of users.' -- source: https://techcrunch.com/2019/07/05/isp-group-mozilla-internet-villain-dns-pr… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Skype Snap App Remains Hopelessly Outdated
by Peter Reutemann 10 Jul '19

10 Jul '19

'The official Skype Snap app for Linux has not been updated in nearly six months, and Microsoft is yet to say why. When introducing the cross-distro build in early 2018, the company said the Skype Snap app would give it the "... ability to push the latest features straight to our users, no matter which device or distribution they happen to use." Clearly, not. Because at the time of writing this post the Skype Snap app sits on version 8.34.0.78, which the Snapcraft store reports was 'last updated' in November 2018. However, the "regular" Linux version available to download from the Skype website is on version 8.47.0.73, released June 2019.' -- source: https://linux.slashdot.org/story/19/07/09/2014250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

IBM Closes Its $34 Billion Acquisition of Red Hat
by Peter Reutemann 09 Jul '19

09 Jul '19

'IBM closed its $34 billion acquisition of Red Hat, the companies announced Tuesday. From a report: The deal was originally announced in October, when the companies said IBM would buy all shares in Red Hat for $190 each in cash. The acquisition of Red Hat, an open-source, enterprise software maker, marks the close of IBM's largest deal ever. It's one of the biggest in U.S. tech history. Excluding the AOL-Time Warner merger, it follows the $67 billion deal between Dell and EMC in 2016 and JDS Uniphase's $41 billion acquisition of optical-component supplier SDL in 2000. Under the deal, Red Hat will now be a unit of IBM's hybrid cloud division, according to the original announcement. The companies said Red Hat's CEO, Jim Whitehurst, would join IBM's senior management team and report to CEO Ginni Rometty. IBM previously said it hoped its acquisition of Red Hat will help it do more work in the cloud, one of its four key growth drivers, which are also social, mobile and analytics. The company lags behind Amazon and Microsoft in the cloud infrastructure business. IBM has seen three consecutive quarters of declining year-over-year revenue. But some analysts are hopeful about the Red Hat deal's opportunity to bring in new business.' -- source: https://linux.slashdot.org/story/19/07/09/1740223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Logitech Wireless USB Dongles Vulnerable To New Hijacking Flaws
by Peter Reutemann 09 Jul '19

09 Jul '19

'A security researcher has publicly disclosed new vulnerabilities in the USB dongles (receivers) used by Logitech wireless keyboards, mice, and presentation clickers. New submitter raikoseagle shares a report: The vulnerabilities allow attackers to sniff on keyboard traffic, but also inject keystrokes (even into dongles not connected to a wireless keyboard) and take over the computer to which a dongle has been connected. When encryption is used to protect the connection between the dongle and its paired device, the vulnerabilities also allow attackers to recover the encryption key. Furthermore, if the USB dongle uses a "key blacklist" to prevent the paired device from injecting keystrokes, the vulnerabilities allow the bypassing of this security protection system. Marcus Mengs, the researcher who discovered these vulnerabilities, said he notified Logitech about his findings, and the vendor plans to patch some of the reported issues, but not all.' -- source: https://it.slashdot.org/story/19/07/09/182246 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Raspberry Pi Admits To Faulty USB-C Design On the Pi 4
by Peter Reutemann 09 Jul '19

09 Jul '19

'The Raspberry Pi 4 was announced two weeks ago as a major new upgrade to the line of cheap single-board hobbyist computers. The Pi 4 featured a faster CPU, options for up to 4GB of RAM, and a new, modern USB-C port for power delivery. The Pi 4 was the Raspberry Pi Foundation's first ever USB-C device, and, well, they screwed it up. As detailed by Tyler Ward, the Raspberry Pi 4 has a non-compliant USB-C charging port and doesn't work with as many chargers as it should. Thanks to the open nature of Raspberry Pi (even the schematics are online!), Ward was able to discover that Raspberry Pi just didn't design its USB-C port correctly. Two "CC" pins on a USB-C port are supposed to each get their own 5.1K ohms resistor, but Raspberry Pi came up with its own circuit design that allows them to share a single resistor. This is not a compliant design and breaks compatibility with some of the more powerful USB-C chargers out there. Whether your USB-C charger works with the Pi 4 has to do with whether it uses an "e-marked" cable. E-marked cables are fully featured USB-C cables with chips inside that negotiate power management, accessory modes, data rates, and other communication specs. Since the Pi 4 USB-C port is wired incorrectly, these smart cables will detect the Pi 4 as an "Audio Adaptor Accessory" and refuse to charge them. Usually, e-marked cables are more expensive and come with larger, higher-powered items, like a USB-C laptop. After reports started popping up on the Internet, Raspberry Pi cofounder Eben Upton admitted to TechRepublic that "A smart charger with an e-marked cable will incorrectly identify the Raspberry Pi 4 as an audio adapter accessory and refuse to provide power." Upton went on to say, "I expect this will be fixed in a future board revision, but for now users will need to apply one of the suggested workarounds. It's surprising this didn't show up in our (quite extensive) field testing program."' -- source: https://hardware.slashdot.org/story/19/07/09/1934205 I'll stick with my RPi3 for the time being...

Mozilla Blocks UAE Bid To Become an Internet Security Guardian After Hacking Reports
by Peter Reutemann 09 Jul '19

09 Jul '19

'Firefox browser maker Mozilla is blocking the United Arab Emirates' government from serving as one of its internet security gatekeepers, citing Reuters reports on a UAE cyber espionage program. From a report: Mozilla said in a statement on Tuesday it was rejecting the UAE's bid to become a globally recognized internet security watchdog, empowered to certify the safety of websites for Firefox users. Mozilla said it made the decision because cybersecurity firm DarkMatter would have administered the gatekeeper role and it had been linked by Reuters and other reports to a state-run hacking program. Reuters reported in January that Abu Dhabi-based DarkMatter provided staff for a secret hacking operation, codenamed Project Raven, on behalf of an Emirati intelligence agency. The unit was largely comprised of former U.S. intelligence officials who conducted offensive cyber operations for the UAE government. Former Raven operatives told Reuters that many DarkMatter executives were unaware of the secretive program, which operated from a converted Abu Dhabi mansion away from DarkMatter's headquarters.' -- source: https://tech.slashdot.org/story/19/07/09/1945241 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox 68 Arrives With Darker Reader View, Recommended Extensions, and IT Customizations
by Peter Reutemann 09 Jul '19

09 Jul '19

'Mozilla today launched Firefox 68 for Windows, Mac, Linux, Android, and iOS. Firefox 68 includes a darker reader view, recommended extensions, IT Pro customizations, and more. From a report: As part of this release, Mozilla has curated a list of recommended extensions "that have been thoroughly reviewed for security, usability, and usefulness." You can find the list on the Get Add-ons page in the Firefox Add-ons Manager (about:addons). While Firefox has had dark mode for months, the Reader View's dark contrast only covered the text area. Now, when you change the contrast to dark, all sections of the site (including sidebars and toolbars) will be immersed in dark mode. With Firefox 60, Mozilla introduced an enterprise version of the browser that employers can customize. This let IT professionals configure Firefox for their organization, either using Group Policy on Windows or a JSON file that works across Windows, Mac, and Linux. With Firefox 68, Mozilla has added more enterprise policies -- to configure or remove the new tab page, turn off search suggestions, and so on.' -- source: https://news.slashdot.org/story/19/07/09/1959238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
