Citrix Devices Are Being Abused as DDoS Attack Vectors
by Peter Reutemann 26 Dec '20

26 Dec '20

'Threat actors have discovered a way to bounce and amplify junk web traffic against Citrix ADC networking equipment to launch DDoS attacks. From a report: While details about the attackers are still unknown, victims of these Citrix-based DDoS attacks have mostly included online gaming services, such as Steam and Xbox, sources have told ZDNet earlier today. The first of these attacks have been detected last week and documented by German IT systems administrator Marco Hofmann. Hofmann tracked the issue to the DTLS interface on Citrix ADC devices. DTLS, or Datagram Transport Layer Security, is a more version of the TLS protocol implemented on the stream-friendly UDP transfer protocol, rather than the more reliable TCP. Just like all UDP-based protocols, DTLS is spoofable and can be used as a DDoS amplification vector.

Up To 3 Million Devices Infected By Malware-Laced Chrome and Edge Add-Ons
by Peter Reutemann 17 Dec '20

17 Dec '20

'As many as 3 million people have been infected by Chrome and Edge browser extensions that steal personal data and redirect users to ad or phishing sites, a security firm said on Wednesday. Ars Technica reports: In all, researchers from Prague-based Avast said they found 28 extensions for the Google Chrome and Microsoft Edge browsers that contained malware. The add-ons billed themselves as a way to download pictures, videos, or other content from sites including Facebook, Instagram, Vimeo, and Spotify. At the time this post went live, some, but not all, of the malicious extensions remained available for download from Google and Microsoft. Avast researchers found malicious code in the JavaScript-based extensions that allows them to download malware onto an infected computer. In a post, the researchers wrote: "Users have also reported that these extensions are manipulating their internet experience and redirecting them to other websites. Anytime a user clicks on a link, the extensions send information about the click to the attacker's control server, which can optionally send a command to redirect the victim from the real link target to a new hijacked URL before later redirecting them to the actual website they wanted to visit. User's privacy is compromised by this procedure since a log of all clicks is being sent to these third party intermediary websites. The actors also exfiltrate and collect the user's birth dates, email addresses, and device information, including first sign in time, last login time, name of the device, operating system, used browser and its version, even IP addresses (which could be used to find the approximate geographical location history of the user)." The researchers don't yet know if the extensions came with the malicious code preinstalled or if the developers waited for the extensions to gain a critical mass of users and only then pushed a malicious update. It's also possible that legitimate developers created the add-ons and then unknowingly sold them to someone who intended to use them maliciously. [...] The list Avast provides in its blog post includes links to download locations for both Chrome and Edge. Anyone who has downloaded one of these add-ons should remove it immediately and run a virus scan.

Google Will Officially Support Running Chrome OS On Old PCs
by Peter Reutemann 16 Dec '20

16 Dec '20

'This week, Google acquired a company called Neverware that allows users to turn their old PCs and Macs into a Chromebook with its CloudReady software. Now, Google is planning to make CloudReady into an official Chrome OS release. Engadget reports: When that happens, Neverware says its existing users will be able to seamlessly upgrade to the updated software. Moreover, once that transition is complete, Google will support CloudReady in the same way that it currently does Chrome OS. In the immediate future, Neverware says it's business as usual. The Home Edition of CloudReady isn't changing, and the company says it's committed to supporting its existing education and enterprise customers. Moreover, there's no plan to change pricing at the moment, and Google will honor any current multi-year licenses. Not only does this acquisition make a lot of sense from Google's perspective, but it's hard to see a downside for CloudReady users. The fact the operating system wasn't officially supported by Google was one of the few downsides to the software. It meant you couldn't install Android apps on CloudReady devices, even though it's based on Chromium OS. With this acquisition, support for Android apps becomes much more likely. Direct support from Google will also make the software more appealing to schools and businesses since they can get help directly from the company if they have any technical issues.' -- source: https://tech.slashdot.org/story/20/12/16/219202 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/

Australia Sues Facebook Over Its Use of Onavo To Snoop
by Peter Reutemann 16 Dec '20

16 Dec '20

'Australia's Competition and Consumer Commission (ACCC) is suing Facebook over its use, in 2016 and 2017, of the Onavo VPN app to spy on users for commercial purposes. From a report: The ACCC's case accuses Facebook of false, misleading or deceptive conduct toward thousands of Australian consumers, after it had promoted the Onavo Protect app -- saying it would keep users personal activity data private, protected and secret and not use it for any other purpose, when it was being used to gather data to help Facebook's business. "Through Onavo Protect, Facebook was collecting and using the very detailed and valuable personal activity data of thousands of Australian consumers for its own commercial purposes, which we believe is completely contrary to the promise of protection, secrecy and privacy that was central to Facebook's promotion of this app," said ACCC chair Rod Sims in a statement. "Consumers often use VPN services because they care about their online privacy, and that is what this Facebook product claimed to offer. In fact, Onavo Protect channelled significant volumes of their personal activity data straight back to Facebook."' -- source: https://yro.slashdot.org/story/20/12/16/1652247 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/

Gmail Is Broken Right Now, One Day After a Massive Outage
by Peter Reutemann 16 Dec '20

16 Dec '20

'TechCrunch: While it doesn't appear to be completely down like it was yesterday morning, we're hearing many reports from Gmail users that the email service is having major issues right now. Some users are reporting that Gmail is particularly slow, while others are reporting constant error messages. One TechCrunch writer, meanwhile, noticed that emails he was sending to Gmail accounts appeared to immediately bounce, with Gmail's server responding with an error reading "550-5.1.1 The email account that you tried to reach does not exist." Google confirms the issues on its services dashboard, writing at 1:30 PM Pacific that they're impacting a "significant" number of users: "We're aware of a problem with Gmail affecting a significant subset of users. The affected users are able to access Gmail, but are seeing error messages, high latency, and/or other unexpected behavior." In a second update at 2:30 PM, Google says its teams are "continuing to investigate this issue"; as of 3:30 PM, the company says it expects the issues to be fixed by 4:00 PM while noting that time may change. Google says the problems have been resolved, although encrypted email service ProtonMail tweets that the email bouncing issue is widespread, with many emails sent to Gmail users bouncing permanently.' -- source: https://tech.slashdot.org/story/20/12/16/0231237 Yeah, I'm one of those affected by this outage. Haven't been receiving a bunch of emails (but really random, some come through whilst others don't)... In Gmail's defence, I haven't had many problems over all these years!

Microsoft and Industry Partners Seize Key Domain Used In SolarWinds Hack
by Peter Reutemann 15 Dec '20

15 Dec '20

'ZDNet: Microsoft and a coalition of tech companies have intervened today to seize and sinkhole a domain that played a central role in the SolarWinds hack, ZDNet has learned from sources familiar with the matter. The domain in question is avsvmcloud[.]com, which served as command and control (C&C) server for malware delivered to around 18,000 SolarWinds customers via a trojanized update for the company's Orion app. SolarWinds Orion updates versions 2019.4 through 2020.2.1, released between March 2020 and June 2020, contained a strain of malware named SUNBURST (also known as Solorigate). Once installed on a computer, the malware would sit dormant for 12 to 14 days and then ping a subdomain of avsvmcloud[.]com. According to analysis from security firm FireEye, the C&C domain would reply with a DNS response that contained a CNAME field with information on another domain from where the SUNBURST malware would obtain further instructions and additional payloads to execute on an infected company's network. Earlier today, a coalition of tech companies seized and sinkholed avsvmcloud[.]com, transferring the domain into Microsoft's possession. Sources familiar with today's actions described the takedown as "protective work" done to prevent the threat actor behind the SolarWinds hack from delivering new orders to infected computers.' -- source: https://it.slashdot.org/story/20/12/15/2117255 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/

CloudLinux To Invest More Than a Million Dollars a Year Into CentOS Clone
by Peter Reutemann 15 Dec '20

15 Dec '20

'ZDNet: When Red Hat, CentOS's Linux parent company, announced it was "shifting focus from CentOS Linux, the rebuild of Red Hat Enterprise Linux (RHEL), to CentOS Stream, which tracks just ahead of a current RHEL release," it lost a lot of friends. CentOS co-founder, Gregory Kurtzer, immediately announced he'd create his own RHEL clone and CentOS replacement: Rocky Linux. He wasn't the only one. CloudLinux also proclaimed it would create a new CentOS clone Lenix. And, CloudLinux will be putting over a million dollars a year behind it. Why? Igor Seletskiy, CloudLinux CEO and founder, explained, "Red Hat's announcement has left users looking for an alternative with all that CentOS provides and without the disruption of having to move to alternative distributions. We promise to dedicate the resources required to Project Lenix that will ensure impartiality and a not-for-profit community initiative. CloudLinux already has the assets, infrastructure, and experience to carry out the mission, and we promise to be open about the process of developing Project Lenix." [...] Project Lenix will be a free, open-source, community-driven, 1:1 binary compatible fork of RHEL 8 (and future releases). For CentOS users, the company promises Lenix will provide an uninterrupted way to convert existing CentOS servers with absolutely zero downtime or need to reinstall anything. The company even claims you'll be able to port entire CentOS server fleets with a single command with no reinstallation or reboots required. That's a bold claim. But CloudLinux already does that trick with its commercial Linux distribution. If the company says it can do it, I think it can. Lenix is only a placeholder name, notes ZDNet. "[A] yet to be formed governing board will decide on a permanent name for the distribution. If all goes well, the first software release will appear in the first quarter of 2021."' -- source: https://linux.slashdot.org/story/20/12/15/0218245 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/

Group that hacked SolarWinds can bypass MFA account protections
by Peter Reutemann 15 Dec '20

15 Dec '20

'The hackers behind the supply chain attack that compromised public and private organizations have devised a clever way to bypass multi-factor-authentication systems protecting the networks they target. Researchers from security firm Volexity said on Monday that it had encountered the same attackers in late 2019 and early 2020 as they penetrated deep inside of a think tank organization no fewer than three times. During one of the intrusions, Volexity researchers noticed the hackers using a novel technique to bypass MFA protections provided by Duo. After having gained administrator privileges on the infected network, the hackers used those unfettered rights to steal a Duo secret known as an akey from a server running Outlook Web App, which enterprises use to provide account authentication for various network services.' -- source: https://arstechnica.com/information-technology/2020/12/solarwinds-hackers-h… 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/
