Israeli Spy Tech Firm Says It Can Break Into Signal App
by Peter Reutemann 15 Dec '20

15 Dec '20

'Last Thursday, Israeli phone-hacking firm Cellebrite said in a blog post that it can now break into Signal, an encrypted app considered safe from external snooping. Haaretz reports: Cellebrite's flagship product is the UFED (Universal Forensic Extraction Device), a system that allows authorities to unlock and access the data of any phone in their possession. Another product it offers is the Physical Analyzer, which helps organize and process data lifted from the phone. Last Thursday, the company announced that the analyzer has now been updated with a new capability, developed by the firm, that allows clients to decode information and data from Signal. Signal, owned by the Signal Technology Foundation, uses a special open source encryption system called Signal Protocol, which was thought to make it nigh-on impossible for a third party to break into a conversation or access data being shared on the platform. It does so by employing what's called "end-to-end encryption." According to Cellebrite's announcement last week, "Law enforcement agencies are seeing a rapid rise in the adoption of highly encrypted apps like Signal, which incorporate capabilities like image blurring to stop police from reviewing data. "Criminals are using this application to communicate, send attachments, and making [sic] illegal deals that they want to keep discrete [sic] and out of sight from law enforcement," the blog post added. Despite support for the app's encryption capabilities, Cellebrite noted that "Signal is an encrypted communication application designed to keep sent messages and attachments as safe as possible from 3rd-party programs. "Cellebrite Physical Analyzer now allows lawful access to Signal app data. At Cellebrite, we work tirelessly to empower investigators in the public and private sector to find new ways to accelerate justice, protect communities, and save lives." In an earlier, now deleted, version of the blog post, the company went as far as to say: "Decrypting Signal messages and attachments was not an easy task. It required extensive research on many different fronts to create new capabilities from scratch. At Cellebrite, however, finding new ways to help those who make our world a safer place is what we're dedicated to doing every day." The initial post, which was stored on the Internet Archive, also included a detailed explanation of how Cellebrite "cracked the code" by reviewing Signal's own open source protocol and using it against it. The company noted in the deleted blog post that "because [Signal] encrypts virtually all its metadata to protect its users, efforts have been put forward by legal authorities to require developers of encrypted software to enable a 'backdoor' that makes it possible for them to access people's data. Until such agreements are reached, Cellebrite continues to work diligently with law enforcement to enable agencies to decrypt and decode data from the Signal app."' -- source: https://it.slashdot.org/story/20/12/14/2241230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

~18,000 organizations downloaded backdoor planted by Cozy Bear hackers
by Peter Reutemann 14 Dec '20

14 Dec '20

'About 18,000 organizations around the world downloaded network management tools that contained a backdoor that spies believed to be backed by the Russian government could use to install additional malware that stole sensitive data, the tools provider, SolarWinds, said on Monday. The disclosure from Austin, Texas-based software maker SolarWinds, came a day after the US government revealed a major security breach hitting federal agencies and private companies. The US Departments of Treasury, Commerce, and Homeland Security departments were among the federal agencies on the receiving end of attacks that gave access to email and other sensitive resources. Federal agencies using the software were instructed on Sunday to disconnect systems that run the software and perform a forensic analysis of their networks. Premiere security firm FireEye says it was breached by nation-state hackers Security firm FireEye, which last week disclosed a serious breach of its own network, said that hackers backed by a nation state compromised a SolarWinds software update mechanism and then used it to infect selected customers who installed a backdoored version of the company’s Orion network management tool. The backdoor infected customers who installed an update from March to June of this year, SolarWinds said in a document filed on Monday with the Securities and Exchange Commission. SolarWinds, which said SolarWinds has about 300,000 Orion customers, put the number of affected customers at about 18,000.' -- source: https://arstechnica.com/information-technology/2020/12/18000-organizations-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Wormable code-execution flaw in Cisco Jabber has a severity rating of 9.9 out of 10
by Peter Reutemann 13 Dec '20

13 Dec '20

'Cisco has patched its Jabber conferencing and messaging application against a critical vulnerability that made it possible for attackers to execute malicious code that would spread from computer to computer with no user interaction required. Again. A single text is all it took to unleash code-execution worm in Cisco Jabber The vulnerability, which was first disclosed in September, was the result of several flaws discovered by researchers at security firm Watchcom Security. First, the app failed to properly filter potentially malicious elements contained in user-sent messages. The filter was based on an incomplete blocklist that could be bypassed using a programming attribute known as onanimationstart. Messages that contained the attribute passed directly to DOM of an embedded browser. Because the browser was based on the Chromium Embedded Framework, it would execute any scripts that made it through the filter. With the filter bypassed, the researchers still had to find a way to break out of a security sandbox that’s designed to keep user input from reaching sensitive parts of the operating system. The researchers eventually settled on a function called CallCppFunction, which among other things Cisco Jabber uses to open files one user receives from another. [...] The researchers recommended that the updates be installed as soon as possible. Until all employees are patched, organizations should consider disabling all external communications. The vulnerabilities affect all currently supported versions of the Cisco Jabber client (12.1 through 12.9).' -- source: https://arstechnica.com/information-technology/2020/12/wormable-zero-click-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hackers Are Selling More Than 85,000 MySQL Databases On a Dark Web Portal
by Peter Reutemann 13 Dec '20

13 Dec '20

'For the past year, hackers have been breaking into MySQL databases, downloading tables, deleting the originals, and leaving ransom notes behind, telling server owners to contact the attackers to get their data back. If database owners don't respond and ransom their data back in nine days, the databases are then put up on auction on a dark web portal. "More than 85,000 MySQL databases are currently on sale on a dark web portal for a price of only $550/database," reports ZDNet: This suggests that both the DB intrusions and the ransom/auction web pages are automated and that attackers don't analyze the hacked databases for data that could contain a higher concentration of personal or financial information. Signs of these ransom attacks have been piling up over the course of 2020, with the number of complaints from server owners finding the ransom note inside their databases popping up on Reddit, the MySQL forums, tech support forums, Medium posts, and private blogs.' -- source: https://developers.slashdot.org/story/20/12/12/1943216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Open Source Developers Say Securing Their Code Is 'Insufferably Boring' and 'Soul-Withering'
by Peter Reutemann 13 Dec '20

13 Dec '20

'"A new survey of the free and open-source software (FOSS) community conducted by the Linux Foundation suggests that contributors spend less than 3% of their time on security issues and have little desire to increase this," reports TechRepublic: Moreover, responses indicated that many respondents had little interest in increasing time and effort on security. One respondent commented that they "find the enterprise of security a soul-withering chore and a subject best left for the lawyers and process freaks," while another said: "I find security an insufferably boring procedural hindrance." The researchers concluded that a new approach to the security and auditing of FOSS would be needed to improve security practices, while limiting the burden on contributors. Some of the most requested tools from contributors were bug and security fixes, free security audits, and simplified ways to add security-related tools to their continuous integration (CI) pipelines. "There is a clear need to dedicate more effort to the security of FOSS, but the burden should not fall solely on contributors," read the report. "Developers generally do not want to become security auditors; they want to receive the results of audits..." The researchers continued: "One way to improve a rewrite's security is to switch from memory-unsafe languages (such as C or C++ ) into memory-safe languages (such as nearly all other languages)," researchers said. "This would eliminate entire classes of vulnerabilities such as buffer overflows and double-frees." Also interesting: money "scored very low in developers' motivations for contributing to open-source projects, as did a desire for recognition amongst peers," according to TechRepublic. "Instead, developers said they were purely interested in finding features, fixes and solutions to the open-source projects they were working on. Other top motivations included were enjoyment and a desire to contribute back to the FOSS projects that they used."' -- source: https://news.slashdot.org/story/20/12/12/205206 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Here Comes the Google Chrome Change that Worries Ad-Blocker Creators
by Peter Reutemann 13 Dec '20

13 Dec '20

'CNET reports: With the next version of Chrome, Google is moving ahead with a plan to improve privacy and security by reining in some abilities of extensions used to customize the browser. The move had angered some developers who expected earlier it would cripple ad blockers. Manifest v3, the programming interface behind Google's security plans, will arrive with Chrome 88 in mid-January, Google said Wednesday at the Chrome Dev Summit. Extensions using the earlier Manifest v2 will still work for at least a year... Among other things, Manifest v3 limits the number of "rules" that extensions may apply to a web page as it loads. Rules are used, for example, to check if a website element comes from an advertiser's server and should therefore be blocked. Google announced the changes two years ago. Reducing the number of rules allowed angered creators of extensions like the uBlock Origin ad blocker and the Ghostery tracking blocker. They said the rules limits will stop their extensions from running their full lists of actions to screen ads or block tracking. That could let websites bypass extensions — and the preferences of people who installed them... The shift brought on by Manifest V3 will spread to all browsers, to the detriment of ad blocking software, predicted Andrey Meshkov, co-founder and chief technology officer of AdGuard, an ad-blocking extension... Ghostery is working to update its extension for Manifest V3 but would rather spend its time on "real privacy innovations," President Jeremy Tillman said in a statement Wednesday. "We still have real misgivings that these changes have more to do with Google protecting its bottom line than it does with improving security for Chrome users...." The importance of the Chrome team's choices are magnified by the fact that other browsers, including Microsoft Edge, Vivaldi , Opera and Brave, are built on its Chromium open-source foundation. Microsoft said it will embrace Manifest v3, too. "Another Manifest v3 change is that extensions no longer may update their abilities by downloading code from third-party sites. "The entire extension now must be distributed through the Chrome Web Store, a measure Google says improves security screens and speeds reviews."' -- source: https://tech.slashdot.org/story/20/12/13/0012217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Accessing Judicial Records Online
by Lawrence D'Oliveiro 12 Dec '20

12 Dec '20

This article <https://arstechnica.com/tech-policy/2020/12/us-house-passes-bill-to-tear-do…> about the ongoing can of worms that is the PACER online judicial records system in the US prompted me to take a look at our own. I found this page <https://www.courtsofnz.govt.nz/judgments/>, which links conveniently to separate areas for the Supreme Court, Court of Appeal and High Courts at the Ministry of Justice <https://forms.justice.govt.nz/jdo/Introduction.jsp>, District Courts <https://www.districtcourts.govt.nz/> and the Legal Information Institute <http://www.nzlii.org/>. In terms of copyright and redistribution, there is this note on the MoJ page: No copyright exists in respect of judgments or decisions of any New Zealand Court or Tribunal. See Copyright Act 1994 s27(g). Also, I like this note on the help page for the nzlii.org site: Emulated Search Languages If you have used one of the popular online legal database systems (or even if you haven't) you probably do not need to learn anything new. Most Lexis, Status, Info-One, (and for the non-lawyers, even C and agrep) style searches are recognised.

CentOS 8 Ending Next Year To Focus Shift On CentOS Stream
by Peter Reutemann 12 Dec '20

12 Dec '20

'Well here is a surprise for those that have long used CentOS as the community-supported rebuild of Red Hat Enterprise Linux... CentOS 8 will end in 2021 and moving forward CentOS 7 will remain supported until the end of its lifecycle but CentOS Stream will be the focus as the future upstream of RHEL. From a report: For those relying on CentOS 8 to enjoy the reliability and features of Red Hat Enterprise Linux 8 but without the licensing costs, etc, that will end in 2021. At the end of 2021, CentOS 8 will no longer be maintained but CentOS 7 will stick around in a supported maintenance state until 2024. The CentOS Project will be focused moving forward just on CentOS Stream as the upstream/development branch of Red Hat Enterprise Linux. CentOS 8 users are encouraged to begin transitioning to CentOS Stream 8. The CentOS Project announced this shift in focus today via the CentOS Blog. Red Hat's announcement meanwhile is promoting the change as beneficial to CentOS Stream.' -- source: https://linux.slashdot.org/story/20/12/08/2010236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Random Firefox Tweaks
by Lawrence D'Oliveiro 12 Dec '20

12 Dec '20

Been looking at various settings changes you can make in the “about:config” page in Firefox. Here are a couple I have found useful: * keyword.enabled -- set to false to stop Firefox trying to do a search on the contents of the address box if it doesn’t match a URL. This is why I have a search box separate from the address box. * browser.fixup.alternate.enabled -- set to false to stop it helpfully tacking on “www.” and “.com” if the original URL you type doesn’t work. I have occasionally been confused by it complaining about not finding a URL, but showing a different one from the one I typed. By the way, when you first try to view this page, Firefox shows you a warning to ensure you understand the consequences of messing about with settings at this level. It remembers it has shown you this warning by adding the following line to the prefs.js file in your profile: user_pref("browser.aboutConfig.showWarning", false); Firefox seems to overwrite this file when it quits, and reloads it when it is launched again.

Google Says It is Expanding Fuchsia's Open Source Model
by Peter Reutemann 11 Dec '20

11 Dec '20

'Fuchsia is a long-term project to create a general-purpose, open source operating system, and today we are expanding Fuchsia's open source model to welcome contributions from the public. Fuchsia is designed to prioritize security, updatability, and performance, and is currently under active development by the Fuchsia team. We have been developing Fuchsia in the open, in our git repository for the last four years. You can browse the repository history at fuchsia.googlesource.com to see how Fuchsia has evolved over time. We are laying this foundation from the kernel up to make it easier to create long-lasting, secure products and experiences. Starting today, we are expanding Fuchsia's open source model to make it easier for the public to engage with the project. We have created new public mailing lists for project discussions, added a governance model to clarify how strategic decisions are made, and opened up the issue tracker for public contributors to see what's being worked on. As an open source effort, we welcome high-quality, well-tested contributions from all. There is now a process to become a member to submit patches, or a committer with full write access. In addition, we are also publishing a technical roadmap for Fuchsia to provide better insights for project direction and priorities. Some of the highlights of the roadmap are working on a driver framework for updating the kernel independently of the drivers, improving file systems for performance, and expanding the input pipeline for accessibility.' -- source: https://news.slashdot.org/story/20/12/08/2048257 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
