Experts Find Serious Problems With Switzerland's Online Voting System
by Peter Reutemann 22 Feb '19

22 Feb '19

'Switzerland made headlines this month for the transparency of its internet voting system when it launched a public penetration test and bug bounty program to test the resiliency of the system to attack. But after source code for the software and technical documentation describing its architecture were leaked online last week, critics are already expressing concern about the system's design and about the transparency around the public test. Cryptography experts who spent just a few hours examining the leaked code say the system is a poorly constructed and convoluted maze that makes it difficult to follow what's going on and effectively evaluate whether the cryptography and other security measures deployed in the system are done properly. "Most of the system is split across hundreds of different files, each configured at various levels," Sarah Jamie Lewis, a former security engineer for Amazon as well as a former computer scientist for England's GCHQ intelligence agency, told Motherboard. "I'm used to dealing with Java code that runs across different packages and different teams, and this code somewhat defeats even my understanding." She said the system uses cryptographic solutions that are fairly new to the field and that have to be implemented in very specific ways to make the system auditable, but the design the programmers chose thwarts this. "It is simply not the standard we would expect," she told Motherboard. [...] It isn't just outside attackers that are a concern; the system raises the possibility for an insider to intentionally misconfigure the system to make it easier to manipulate, while maintaining plausible deniability that the misconfiguration was unintentional. "Someone could wire the thing in the wrong place and suddenly the system is compromised," said Lewis, who is currently executive director of the Open Privacy Research Society, a Canadian nonprofit that develops secure and privacy-enhancing software for marginalized communities. "And when you're talking about code that is supposed to be protecting a national election, that is not a statement someone should be able to make." "You expect secure code to be defensively written that would prevent the implementers of the code from wiring it up incorrectly," Lewis told Motherboard. But instead of building a system that doesn't allow for this, the programmers simply added a comment to their source code telling anyone who compiles and implements it to take care to configure it properly, she said. The online voting system was developed by Swiss Post, the country's national postal service, and the Barcelona-based company Scytl. "Scytl claims the system uses end-to-end encryption that only the Swiss Electoral Board would be able to decrypt," reports Motherboard. "But there are reasons to be concerned about such claims."' -- source: https://developers.slashdot.org/story/19/02/21/2227234 At least they had a public test to figure that out, rather than an actual election...

Millions of websites threatened by highly critical code-execution bug in Drupal
by Peter Reutemann 22 Feb '19

22 Feb '19

'Millions of sites that run the Drupal content management system run the risk of being hijacked until they're patched against a vulnerability that allows hackers to remotely execute malicious code, managers of the open source project warned Wednesday. CVE-2019-6340, as the flaw is tracked, stems from a failure to sufficiently validate user input, managers said in an advisory. Hackers who exploited the vulnerability could, in some cases, run code of their choice on vulnerable websites. The flaw is rated highly critical. "Some field types do not properly sanitize data from non-form sources," the advisory stated. "This can lead to arbitrary PHP code execution in some cases."' -- source: https://arstechnica.com/information-technology/2019/02/millions-of-websites… 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/

Severe Vulnerabilities Uncovered In Popular Password Managers
by Peter Reutemann 21 Feb '19

21 Feb '19

Not sure whether this also applies to the Linux/cross-platform versions... 'Independent Security Evaluators (ISE) published an assessment on Tuesday with the results of testing with several popular password managers, including LastPass and KeePass. The team said that each password management solution "failed to provide the security to safeguard a user's passwords as advertised" and "fundamental flaws" were found that "exposed the data they are designed to protect." The vulnerabilities were found in software operating on Windows 10 systems. In one example, the master password which users need to use to access their cache of credentials was stored in PC RAM in a plaintext, readable format. ISE was able to extract these passwords and other login credentials from memory while the password manager in question was locked. It may be possible that malicious programs downloaded to the same machine by threat actors could do the same. The report has summarized the main findings based on each password management solution. Here's what ISE had to say about LastPass and KeePass -- two of the most popular password managers available: "LastPass obfuscates the master password while users are typing in the entry, and when the password manager enters an unlocked state, database entries are only decrypted into memory when there is user interaction. However, ISE reported that these entries persist in memory after the software enters a locked state. It was also possible for the researchers to extract the master password and interacted-with password entries due to a memory leak." "KeePass scrubs the master password from memory and is not recoverable. However, errors in workflows permitted the researchers from extracting credential entries which have been interacted with. In the case of Windows APIs, sometimes, various memory buffers which contain decrypted entries may not be scrubbed correctly."' -- source: https://it.slashdot.org/story/19/02/21/070204 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/

Oracle Claims a Fighter of Pirated Apps is a Front For Ad Fraud
by Peter Reutemann 21 Feb '19

21 Feb '19

'A company that claims to combat app piracy is a pirate itself, according to a report Oracle released this week. From a report: Oracle claims the company, Tapcore, has been perpetrating a massive ad fraud on Android devices by infecting apps with software that ring up fake ad impressions and drain people's data. Based in The Netherlands, Tapcore works with developers to identify when apps are pirated and then enables developers to make money from those bootleg copies by serving ads. Oracle says that Tapcore's anti-piracy code was a Trojan horse that was generating fake mobile websites to trick ad serving platforms into paying them for non-existent ad inventory. "The code is delivering a steady stream of invisible video ads and spoofing domains," Dan Fichter, VP of software development at Oracle Data Cloud, tells Ad Age. "On all those impressions it looked like the advertiser was running ads on legitimate mobile websites. Not only were they not on a website, they were on an invisible web browser." On its website, Tapcore says it works with more than 3,000 apps, serving 150 million ad impressions a day. The apps whose pirated versions it has worked with include titles like "Perfect 365," "Draw Clash of Clans," "Vertex" and "Solitaire: Season 4," according to Oracle's report.' -- source: https://yro.slashdot.org/story/19/02/21/1238254 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 Researchers Say Software Alone Can't Mitigate Spectre Chip Flaws
by Peter Reutemann 21 Feb '19

21 Feb '19

'A group of researchers say that it will be difficult to avoid Spectre bugs in the future unless CPUs are dramatically overhauled. From a report: Google researchers say that software alone is not enough to prevent the exploitation of the Spectre flaws present in a variety of CPUs. The team of researchers -- including Ross McIlroy, Jaroslav Sevcik, Tobias Tebbi, Ben L Titzer and Toon Verwaest -- work on Chrome's V8 JavaScript engine. The researchers presented their findings in a paper distributed through ArXiv and came to the conclusion that all processors that perform speculative execution will always remain susceptible to various side-channel attacks, despite mitigations that may be discovered in future.

A Psion Palmtop Successor Has Arrived and It Runs Android and Linux
by Peter Reutemann 21 Feb '19

21 Feb '19

'A lot of people probably remember the 1990s palmtop computers made by Psion fondly. The clamshell-design palmtops were pocketable, black and white, but had a working stylus and a fantastic tactile foldout QWERTY keyboard that you could type pretty substantial documents on or even write code with. A different company -- Planet Computers -- has now produced a spiritual successor to the old Psion palmtops called the Gemini PDA that is much like an old Psion but with the latest Android smartphone hardware in it and a virtually identical tactile keyboard. It can also dual boot to Linux (Debian, Ubuntu, Sailfish) alongside Android. The technical specs are a MediaTek deca-core processor, 4GB RAM, 64GB storage (plus microSD slot), 4G, 802.11c Wi-Fi, GPS, Bluetooth, eSIM support, and 4,220mAh battery. The screen measures in at 5.99-inches with a 2,160 x 1,080 (403ppi) resolution. The only thing missing seems to be the stylus -- but perhaps that would have complicated manufacturing of this niche-device in its first production r' -- source: https://hardware.slashdot.org/story/19/02/20/2241216 Yes, it's back! :-) 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/

Blu-Ray On The Way Out?
by Lawrence D'Oliveiro 20 Feb '19

20 Feb '19

Samsung has given up developing new Blu-Ray players, and is going to stop selling them in the US altogether <https://arstechnica.com/gadgets/2019/02/samsung-says-it-will-stop-making-ne…>. Seems like downloads and streaming are taking over from physical discs, and UHD was never a big part of the latter anyway. One surprising fact is that DVD-Video still accounts for over half of such sales, at least in the US.
