Google Promises To Play Nice With Ad Blockers (Again)
by Peter Reutemann 13 Jun '19

13 Jun '19

'After being ripped to shreds by angry users, Google engineers have promised this week that the upcoming changes to Chrome's extensions system won't cripple ad blockers, as everyone is fearing. Instead, the company claims that the new extension API changes will actually improve user privacy and bring speed improvements. Furthermore, Google also promised to raise a maximum limit in one of the upcoming APIs that should address and lay to rest the primary criticism brought against the new extensions API by developers of ad blockers during the last six months.' -- source: https://tech.slashdot.org/story/19/06/13/1522245 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/

System76's Supercharged Linux-powered Gazelle Laptop is Finally Available
by Peter Reutemann 13 Jun '19

13 Jun '19

'The System76 Gazelle laptop is finally available. From a report: What makes this laptop so special (besides its pre-installed Linux-based operating System), is its impressive specifications. You see, System76 has supercharged it with a 9th generation Intel Core i7 Processor (9750H) and NVIDIA GTX 16-Series Graphics. It even has something the pricey MacBook Pro doesn't -- the ability to be configure with up to 64GB. Yeah, Apple's laptop can only have a maximum of 32GB. The Gazelle can be configured with additional top specs, such as an NVMe SSD up to 2TB. Actually, it can accommodate two such drives, so you can theoretically have 4TB of speedy storage. You can opt for either a 15 or 17-inch display, both of which have a 1080p resolution. Regardless of screen size, you get a full keyboard too, meaning it has a number pad on the right. It ships with Ubuntu or Pop!_OS pre-installed and starts at $1099.' -- source: https://hardware.slashdot.org/story/19/06/13/189249 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/

Yubico To Replace Vulnerable YubiKey FIPS Security Keys
by Peter Reutemann 13 Jun '19

13 Jun '19

'Yubico said today it plans to replace certain hardware security keys because of a firmware flaw that reduces the randomness of cryptographic keys generated by its devices. From a report: Affected products include models part of the YubiKey FIPS Series, a line of YubiKey authentication keys certified for use on US government networks (and others) according to the US government's Federal Information Processing Standards (FIPS). According to a Yubico security advisory published today, YubiKey FIPS Series devices that run firmware version 4.4.2 and 4.4.4 contain a bug that keeps "some predictable content" inside the device's data buffer after the power-up operation. This "predictable content" will influence the randomness of cryptographic keys generated on the device for a short period after the boot-up, until the "predictable content" is all used up, and true random data is present in the buffer. This means that for a short period after booting up YubiKey FIPS Series devices with the affected 4.4.2 and 4.4.4 versions will generate keys that can be either recovered partially, or in full, depending on the cryptographic algorithm the key is working with for a particular authentication operation.' -- source: https://tech.slashdot.org/story/19/06/13/1844232 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/

If you haven’t patched Vim or NeoVim text editors, you really, really should
by Peter Reutemann 13 Jun '19

13 Jun '19

'A recently patched vulnerability in text editors preinstalled in a variety of Linux distributions allows hackers to take control of computers when users open a malicious text file. The latest version of Apple’s macOS is continuing to use a vulnerable version, although attacks only work when users have changed a default setting that enables a feature called modelines. Vim and its forked derivative, NeoVim, contained a flaw that resided in modelines. This feature lets users specify window dimensions and other custom options near the start or end of a text file. While modelines restricts the commands available and runs them inside a sandbox that’s cordoned off from the operating system, researcher Armin Razmjou noticed the source! command (including the bang on the end) bypassed that protection.' -- source: https://arstechnica.com/information-technology/2019/06/if-you-havent-patche… 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/

'RAMBleed' Rowhammer Attack Can Now Steal Data, Not Just Alter It
by Peter Reutemann 12 Jun '19

12 Jun '19

' A team of academics from the US, Austria, and Australia, has published new research today detailing yet another variation of the Rowhammer attack. From a report: The novelty in this new Rowhammer variety -- which the research team has named RAMBleed -- is that it can be used to steal information from a targeted device, as opposed to altering existing data or to elevate an attacker's privileges, like all previous Rowhammer attacks, have done in the past. [...] In a research paper [PDF] published today, academics unveiled RAMBleed, the first Rowhammer attack that can actively deduce and steal data from a RAM card. To do this, researchers had to come up and combine different techniques, which, when assembled, would permit a RAMBleed attack to take place.' -- source: https://tech.slashdot.org/story/19/06/11/1931214 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/

The Biggest Data Breach Archive On the Internet Is For Sale
by Peter Reutemann 12 Jun '19

12 Jun '19

'Troy Hunt, the owner and founder of the well-known and respected data breach notification website "Have I Been Pwned," announced today that he's actively looking for a buyer. "To date, every line of code, every configuration and every breached record has been handled by me alone. There is no 'HIBP team,' there's one guy keeping the whole thing afloat," Hunt wrote. "It's time for HIBP to grow up. It's time to go from that one guy doing what he can in his available time to a better-resourced and better-funded structure that's able to do way more than what I ever could on my own." Motherboard reports: Over the years, Have I Been Pwned has become the repository for data breaches on the internet, a place where users can search for their email address and see whether they have been part of a data breach. It's now also a service where people can sign up to get notified whenever their accounts get breached. It's perhaps the most useful, free, cybersecurity service in the world. Hunt said he's already had informal conversations with some organizations that might be interested in buying the service. Hunt said he's engaged the financial consulting firm KPMG to look for a buyer. In the post, Hunt shared some staggering numbers that explain just how big Have I Been Pwned has become: 8 billion breached records, nearly 3 million people subscribed to notifications, who have been emailed about a breach 7 million times, 150,000 unique visitors to the site on a normal day, 10 million on an abnormal day. Regardless of who buys the site, Hunt made a series of commitments on the future of Have I Been Pwned: searches should remain free for consumers, the platform should expand and grow, and, finally, he wants to stay involved in some capacity.

Security Is Always Down To The Weakest Link
by Lawrence D'Oliveiro 11 Jun '19

11 Jun '19

Nice non-paywalled report <https://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=12235615> into how the National Party (and others) were able to obtain supposedly-confidential details of today’s Budget announcements. In summary, a “clone” was made of the Treasury website, containing the Budget info, that was supposed to be swapped for the current production site later today. It was not publicly accessible, at least directly. However, the search function on the public site was inadvertently sucking up the confidential info from the clone server as well, and carefully-worded searches would reveal bits of such info as search context, even if the actual documents being indexed were not accessible in full. The Police have decided that, even though such leaks are considered a serious matter, the accesses were “not unlawful”. Which seems a refreshing change from, say, the UK, where someone was prosecuted and jailed some years ago just for putting “../” into a URL ...
