Apple IOS XML Bug
by Lawrence D'Oliveiro 07 May '20

07 May '20

From <https://www.schneier.com/blog/archives/2020/05/ios_xml_bug.html>: So Siguza's exploit -- which granted an app full access to the entire file system, and more - uses malformed XML comments constructed in a way that one of iOS's XML parsers sees its declaration of entitlements one way, and another XML parser sees it another way. The XML parser used to check whether an application should be allowed to launch doesn't see the fishy entitlements because it thinks they're inside a comment. The XML parser used to determine whether an already running application has permission to do things that require entitlements sees the fishy entitlements and grants permission. Further: Implementing 4 different parsers is just asking for trouble, and the "fix" is of the crappiest sort, bolting on more crap to check they're doing the right thing in this single case. None of this is encouraging. Conway’s Law comes to mind: “any piece of software reflects the organizational structure that produced it”. 3 different XML parsers sounds like 3 different groups working on those parts of the OS, while the addition of a fourth to block the hole suggests that nobody with any responsibility for security was able to get through to any of those groups to fix their parsing.

'A hacker claims to have stolen over 500GB of data from Microsoft's private GitHub repositories, BleepingComputer reports. From the report: This evening, a hacker going by the name Shiny Hunters contacted BleepingComputer to tell us they had hacked into the Microsoft GitHub account, gaining full access to the software giant's 'Private' repositories. The individual told us that they then downloaded 500GB of private projects and initially planned on selling it, but has now decided to leak it for free. Based on the file stamps in the leaked files, the breach may have occurred on March 28th, 2020.' -- source: https://developers.slashdot.org/story/20/05/07/1850248 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/

Google Authenticator's First Android Update in Years Lets You Move Your Account Between Devices
by Peter Reutemann 07 May '20

07 May '20

'Google Authenticator, the company's code-based authentication app, has received its first update in three years, updating the app's interface for larger screens with more modern aspect ratios and delivering one of the platform's most-needed features. From a report: The Android version was last updated on August 22nd, 2017, while the iOS one was updated around a year ago to adjust it for iPhone X screens. Now, for the first time, Authenticator users will be able to easily transfer their account from one device to another without needing to manually transfer each code or disable and reenable two-factor authentication (2FA) on each account. The update introduces this feature through an import / export tool that lets you choose which accounts to include and transfer using a single QR code scan. It's a feature that competitor Authy has provided for quite some time, so it's refreshing to see it come to Authenticator, even if it's years late.' -- source: https://tech.slashdot.org/story/20/05/07/1450227 Finally...

Caddy offers TLS, HTTPS, and more in one dependency-free Go Web server
by Peter Reutemann 06 May '20

06 May '20

'Yesterday, the Caddy Web server reached an important milestone, with its 2.0.0 release. Caddy bills itself as "The Ultimate Server," with no dependencies, automatic TLS certificate obtainment and renewal, and much smaller configuration files than Apache or Nginx. Senior Technology Editor Lee Hutchinson expressed both curiosity about Caddy and his own personal inertia in the Ars slack: Caddy is an app where every time i see it or think of it i say “I should mess with it, it looks neat” and then I never do. I’ve gotten so enmeshed in my haproxy - varnish - nginx stack that breaking out feels like more trouble than it’s worth. I hadn't ever heard of Caddy until Lee mentioned it, but I know a call to action when I hear one.' -- source: https://arstechnica.com/gadgets/2020/05/caddy-offers-tls-https-and-more-in-… 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 76 Arrives With Password Management and Zoom Improvements
by Peter Reutemann 06 May '20

06 May '20

'Mozilla today launched Firefox 76 for Windows, Mac, and Linux. Firefox 76 includes new Firefox Lockwise password functionality, Zoom improvements, and a handful of developer features. From a report: Lockwise, the password management service formerly known as Firefox Lockbox, is getting smarter. The Firefox feature already lets you generate, manage, and protect all those passwords for streaming services, grocery deliveries, and anything else that helps during the pandemic. If you share your device with family or roommates, Lockwise in Firefox 76 can now protect your saved passwords. When you try to view or copy a password from your "Logins and Passwords" page, you will be prompted for your device's account password. [...] Firefox 76 adds support for Audio Worklets, which run custom JavaScript audio processing code for applications like VR and gaming on the web. Unlike their predecessor, ScriptProcessorNode, worklets run off the main thread in a similar way to web workers. Mozilla also notes Audio Worklets are "being adopted by some of your favorite software programs." The company specifically called out Zoom, which has become a phenomenon of its own during the pandemic. In short, you now join Zoom calls in Firefox without having to download or install the Zoom client.' -- source: https://news.slashdot.org/story/20/05/05/160252 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/

Xiaomi Releases Browser Update Amid Accusations It Collects Private Browsing Data
by Peter Reutemann 06 May '20

06 May '20

'Xiaomi released software updates for its browser apps on Monday amid fresh accusations it's been collecting private data from people who use its phones and browser apps. CNET reports: In a blog post, Xiaomi said the update will allow you to switch off aggregated data collection while on incognito mode in its three browser apps: Mi Browser, Mi Browser Pro, and Mint Browser. The software update was rolled out on Google Play. "We believe this functionality, in combination with our approach of maintaining aggregated data in non-identifiable form, goes beyond any legal requirements and demonstrates our company's commitment to user privacy," the company said in its post. The release of the software update comes after a Forbes report published last Thursday raised concerns about the Chinese phone-maker's use of private data. It suggested Xiaomi may be collecting data on the websites users visit as well as granular information about apps used and files opened on devices. In response to the report, Xiaomi defended its practices last week saying it's "fully compliant with user privacy protection laws and regulations in the countries and regions we operate in.' -- source: https://yro.slashdot.org/story/20/05/05/2013244 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/

Ubuntu 20.04: Welcome to the future, Linux LTS disciples
by Peter Reutemann 05 May '20

05 May '20

'This is most definitely the strangest spring in a very long time, with all sorts of event and hardware delays or outright cancellations. But one thing that has arrived right on schedule? The latest version of Ubuntu Linux. Ubuntu 20.04 (Focal Fossa, as this release is known) is a Long Term Support (LTS) release, which means Ubuntu's parent company, Canonical, will provide support through 2025. The LTS releases are what Canonical calls "enterprise grade," and these tend to be conservative when it comes to adopting new technologies. The interim releases, like last year's Ubuntu 19.10, are instead where the company tends to experiment. Perhaps not surprisingly, Canonical estimates that 95 percent of all Ubuntu installations are LTS releases. Which is to say, this is a big update that the bulk of Ubuntu's user base will be upgrading to eventually. The good news for Ubuntu fans is that 20.04 has been a fantastic release in our testing. This update has been very solid in day-to-day use, and it still manages to (optionally!) include support for some cutting-edge new features, like the beginnings of a tool to manage ZFS snapshots. There's also a major kernel bump, and considerable work has gone into improving and polishing the default Yaru theme. That's a running theme in Ubuntu, where much of what makes it great are small changes and new features that individually might not be remarkable but all together create a system that is fast, stable, and hard to beat. The security improvements offered this time around almost alone make Ubuntu 20.04 a must-have upgrade. But the Ubuntu 20.04 update has plenty of new stuff for all the various Ubuntu flavors as well. So even if the default GNOME desktop doesn't excite you, there's big news in Kubuntu, Lubuntu, Ubuntu Mate, and more. There's also some good news for Raspberry Pi users, who get first-class support for the Pi 4 platform out of the box (and when I say first class, I mean, frankly, better than the official Pi distro, Raspian).' -- source: https://arstechnica.com/information-technology/2020/05/ubuntu-20-04-welcome… 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/

Academics Turn PC Power Units Into Speakers To Leak Secrets From Air-Gapped Systems
by Peter Reutemann 04 May '20

04 May '20

'Academics from an Israeli university have published new research last week showing how an attacker could turn a computer's power supply unit into a rudimentary speaker that can secretly transmit data from an infected host using audio waves. From a report: The technique, named POWER-SUPPLaY, is the work of Mordechai Guri, the head of R&D at the Ben-Gurion University of the Negev, in Israel. Over the last half-decade, Guri has been pioneering research into new covert data exfiltration channels. The techniques Guri has been developing can be used for stealing data through unconventional means. Guri has been developing these techniques specifically for extracting data from air-gapped systems -- computers isolated on local networks with no internet access. Such computers are often used on government or corporate networks to store sensitive data, such as classified files or intellectual property. Air-gapped systems are protected by several layers of defenses, on top of the "air gap," and you need novel data transmission techniques to go around these defenses. For example, some air-gapped systems don't have speakers, because it's been proven in the past that speakers could be abused to leak information from a secure system using inaudible sound waves.' -- source: https://it.slashdot.org/story/20/05/04/176208 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/

Google Purged Almost 1,000 Abusive 'Creeperware' Apps. Now Some Are Coming Back.
by Peter Reutemann 04 May '20

04 May '20

'In June 2019, a group of cybersecurity researchers notified Google of more than 1,000 potentially malicious apps on the company's Play Store that can be used to surveil, monitor, and harass users. Their findings, which have not previously been reported, eventually led to one of the largest ever mass removals of Android apps. Less than a year later, there are signs that the "creeperware," as the researchers called it, is returning. From a report: The label comprises a broad category of abusable apps, including tools for spying, spoofing phone numbers, and secretly recording video and audio. Some of those programs banned by Google have now rebranded or added disclaimers and returned to the Play Store. Meanwhile, new programs with overtly abusive purposes have slipped through the company's automated monitoring systems. The initial 1,095 apps flagged by researchers came in a variety of forms. Catch Cheating Spouse and its ilk offered stalkerware packages: Once installed on a victim's phone, the user could track the device's location, read messages, listen to calls, remotely record through the microphone, or log passwords. Many of the programs had innocuous names but hostile purposes. Spoof Text Message, for example, advertised itself with a video using the tagline "Don't like your buddy's girlfriend? Well, break them up!" Others, like GirlFriend Cell Tracker, were more explicit in their motivation. "When we reported these apps to Google initially, it felt like they didn't really know what to do with them," said Kevin Roundy, the technical director of NortonLifeLock's research group, and one of the lead members of the team that uncovered the malicious apps last June.' -- source: https://tech.slashdot.org/story/20/05/04/1528219 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/

Hackers Breach LineageOS Servers Via Unpatched Vulnerability
by Peter Reutemann 04 May '20

04 May '20

'Hackers have gained access to the core infrastructure of LineageOS, a mobile operating system based on Android, used for smartphones, tablets, and set-top boxes. The intrusion took place on Saturday night at around 8 pm (US Pacific coast), and was detected before the attackers could do any harm, the LineageOS team said in a statement published less than three hours after the incident. The LineageOS team said the operating system's source code was unaffected, and so were any operating system builds, which had been already paused since April 30, because of an unrelated issue. Signing keys, used to authenticate official OS distributions, were also unaffected, as these hosts were stored separately from the LineageOS main infrastructure. LineageOS developers said the hack took place after the attacker used an unpatched vulnerability to breach its Salt installation.' -- source: https://it.slashdot.org/story/20/05/04/0341202 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/
