Syntax Errors Are the Doom of Us All, Including Botnet Authors
by Peter Reutemann 07 Dec '22

07 Dec '22

'KmsdBot, a cryptomining botnet that could also be used for denial-of-service (DDOS) attacks, broke into systems through weak secure shell credentials. It could remotely control a system, it was hard to reverse-engineer, didn't stay persistent, and could target multiple architectures. KmsdBot was a complex malware with no easy fix. That was the case until researchers at Akamai Security Research witnessed a novel solution: forgetting to put a space between an IP address and a port in a command. And it came from whoever was controlling the botnet. With no error-checking built in, sending KmsdBot a malformed command -- like its controllers did one day while Akamai was watching -- created a panic crash with an "index out of range" error. Because there's no persistence, the bot stays down, and malicious agents would need to reinfect a machine and rebuild the bot's functions. It is, as Akamai notes, "a nice story" and "a strong example of the fickle nature of technology." KmsdBot is an intriguing modern malware. It's written in Golang, partly because Golang is difficult to reverse-engineer. When Akamai's honeypot caught the malware, it defaulted to targeting a company that created private Grand Theft Auto Online servers. It has a cryptomining ability, though it was latent while the DDOS activity was running. At times, it wanted to attack other security companies or luxury car brands.' -- source: https://it.slashdot.org/story/22/12/06/1552228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Company 'Hijacks' Blender's CC BY-Licensed Film, YouTube Strikes User
by Peter Reutemann 06 Dec '22

06 Dec '22

'TorrentFreak: The Blender Institute develops Blender, a free and open source 3D graphics tool used to create animated films. Sintel and Big Buck Bunny are among Blender's most recognizable titles and due to Creative Commons licensing (CC BY), they are widely shared, used, remixed and reshared. According to original Blender creator Ton Roosendaal, "Open licenses are essential for sharing our films and their source material." Right now, a company is claiming that Blender's free content is actually their content and as a result, must be immediately removed from the internet. We're talking about content that was created with Blender's explicit blessing but even after multiple appeals, not even YouTube will see reason. Bruno Fernandez-Ruiz is the co-founder and CTO at AI-focused driver safety company, Nexar. On Sunday he informed TorrentFreak that he's also an independent film composer and producer, working with music production libraries, and distributing to the main music platforms. TorrentFreak contacted Bruno after noticing a post he made on a music production forum. He wrote that after uploading a video containing a clip from the Blender movie Caminandes 3 -- Llamigos, YouTube notified him that a rightsholder had filed a copyright complaint, his video had been taken down, and a copyright strike had been issued to his account. The complaint, sent by Uzbekistan-based media/news company ZO'R TV, was not the result of automatic matching under Content ID. It was filed as a formal DMCA notice, meaning that someone probably reviewed the details before sending the complaint. The notice claimed that Bruno had infringed ZO'R TV's copyrights by reproducing content (6:21 to 8:26) from this YouTube video published in 2018. Since the content in question is obviously from Blender's film Caminandes 3, ZO'R TV was in no position to issue a DMCA notice. On that basis, Bruno followed the recognized procedure by sending a DMCA counternotice to YouTube. It didn't go well. After filing his counternotice with YouTube, Bruno was informed that since he'd provided insufficient information, YouTube could not process it. However, YouTube did inform Bruno of the risks of filing a counternotice, including that his name could be sent to the claimant, ZO'R TV in this case. Determined to have his video restored, Bruno accepted the risks and sent another counternotice to YouTube. This time there was no indication that the counternotice was deficient. YouTube thanked him for filing it -- but still declined to process it. YouTube's email advised Bruno that counternotices should only be filed in case of a mistake or misidentification. Consulting with a lawyer first might be helpful, YouTube added. After three attempts to restore the video and have the copyright strike removed, YouTube responded once again. The message contained yet more disappointment for Bruno. "Based on the information that you have provided, it appears that you do not have the necessary rights to post the content on YouTube. Therefore, we regretfully cannot honor your request," it advised. This signaled the end of the debate as far as YouTube was concerned and by rejecting Bruno's right to send a counternotice, the platform denied him an opportunity to have the video restored, stand up for Blender's rights, and get the strike removed. After notifying Blender of the situation, Blender developed Ton Roosendaal replied, saying the company has "no staff here available to go after situations like this" but suggested they could "escalate it to the Creative Commons organization." "After all, it's their mission," he added.' -- source: https://news.slashdot.org/story/22/12/05/2212216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint 20.2: Mate / GTK issue?
by Peter Reutemann 05 Dec '22

05 Dec '22

Hi everyone Just in case some one else encounters this problem... Last Friday, I installed the latest kernel update on my Linux Mint 20.2 MATE edition and rebooted the first time in a few weeks. After logging back in, I noticed that the Xorg process was using almost one core on my laptop. This wasn't the case when waiting at the login prompt (i.e., lightdm). Starting my file browser of choice, GTK version of double-command, (package: doublecmd-gtk), seemed to grab another core. Downgrading of Xorg or using an older kernel had no impact, unfortunately. When switching to XFCE4 for my session today, I didn't experience that high CPU load problem anymore. I also switched to the QT version of double-commander (package: doublecmd-qt). Not really solving the problem, more like side-stepping it, but at least I get can work done again, without my laptop fan going hard out all day... And I've used XFCE in the past. :-) Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Today’s New Word: “Cyberdeck”
by Lawrence D'Oliveiro 04 Dec '22

04 Dec '22

What is a “cyberdeck”? According to <https://hackaday.com/tag/cyberdeck/>, it’s basically a style of home-built computer with futuristic/sci-fi/cyberpunk overtones. The name comes from (what else) a William Gibson novel. It seems common to use a Raspberry π as the beating heart, with a custom 3D-printed case around it plus other suitably interesting-looking parts. Angles seem preferable to curves, with asymmetrically-inset polygons very popular. Weird and wacky keyboard layouts are a bonus. The diminutive size of the Raspberry π leaves plenty of room for experimentation. We can build the future-that-never-was! We have the technology now.

Web Browsers Drop Mysterious Company With Ties To US Military Contractor
by Peter Reutemann 02 Dec '22

02 Dec '22

'Washington Post: Major web browsers moved Wednesday to stop using a mysterious software company that certified websites were secure, three weeks after The Washington Post reported its connections to a U.S. military contractor. Mozilla's Firefox and Microsoft's Edge said they would stop trusting new certificates from TrustCor Systems that vouched for the legitimacy of sites reached by their users, capping weeks of online arguments among their technology experts, outside researchers and TrustCor, which said it had no ongoing ties of concern. Other tech companies are expected to follow suit. The Post reported on Nov. 8 that TrustCor's Panamanian registration records showed the same slate of officers, agents and partners as a spyware-maker identified this year as an affiliate of Arizona-based Packet Forensics, which has sold communication interception services to U.S. government agencies for more than a decade. One of those contracts listed the "place of performance" as Fort Meade, Md., the home of the National Security Agency and the Pentagon's Cyber Command. The case has put a new spotlight on the obscure systems of trust and checks that allow people to rely on the internet for most purposes. Browsers typically have more than a hundred authorities approved by default, including government-owned ones and small companies, to seamlessly attest that secure websites are what they purport to be. "Certificate Authorities have highly trusted roles in the internet ecosystem and it is unacceptable for a CA to be closely tied, through ownership and operation, to a company engaged in the distribution of malware," Mozilla's Kathleen Wilson wrote to a mailing list for browser security experts. "Trustcor's responses via their Vice President of CA operations further substantiates the factual basis for Mozilla's concerns."' -- source: https://tech.slashdot.org/story/22/12/01/2113209 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla Acquires Team Behind Pulse, an Automated Status Updater for Slack
by Peter Reutemann 02 Dec '22

02 Dec '22

'Firefox developer Mozilla is making a rare foray into the world of mergers and acquisitions, with news that it has snapped up recently-shuttered California-based productivity startup Pulse. From a report: Terms of the deal haven't been disclosed, but the deal is tantamount to an "acqui-hire," with Mozilla looking to deploy the Pulse team across an array of machine learning (ML) projects. "We're acquiring Pulse for the incredible team they have built," Mozilla chief product officer Steve Teixeira told TechCrunch. "As we look to continue to improve user experiences across all of our products, ML will be a core part of that." Founded out of Menlo Park in 2019, Pulse in its initial guise was a "virtual office" platform called Loop Team, but after honing the idea for a couple of years it pivoted and rebranded last November. Pulse, essentially, was an automated status-updating tool that used signals based on pre-configured integrations and preferences set by the user. For example, users could synchronize Pulse with their calendar and Slack, setting rules to stipulate what their status and corresponding emoji should be based on keywords in their calendar event title. If their schedule for a particular time says "hair appointment" from 12-1pm, then the person's Slack status update might display a scissors emoji alongside the word "haircut." Or, it might say "birthday" alongside a cake emoji if that's what is in their calendar.' -- source: https://tech.slashdot.org/story/22/12/01/1644245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Used thin client PCs are an unsexy, readily available Raspberry Pi alternative
by Peter Reutemann 30 Nov '22

30 Nov '22

'"Raspberry Pi boards are hard to get, probably also next year," says Andreas Spiess, single-board enthusiast and YouTuber, in his distinctive Swiss accent. He's not wrong. Spiess says he and his fellow Pi devotees need "a strategy to survive" without new boards, so he suggests looking in one of the least captivating, most overlooked areas of computing: used, corporate-minded thin client PCs. Spiess' Pi replacements, suggested and refined by many of his YouTube commenters and Patreon subscribers, are Fujitsu Futros, Lenovo ThinkCentres, and other small systems (some or all of which could be semantically considered "thick clients" or simply "mini PCs," depending on your tastes and retro-grouch sensibilities). They're the kind of systems you can easily find used on eBay, refurbished on Amazon Renewed, or through other enterprise and IT asset disposition sources. They're typically in good shape, given their use and environment. And compared to single-board enthusiast systems, many more are being made and replaced each year.' -- source: https://arstechnica.com/gadgets/2022/11/used-thin-client-pcs-are-an-unsexy-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Anker's Eufy Cameras Caught Uploading Content To the Cloud Without User Consent
by Peter Reutemann 30 Nov '22

30 Nov '22

'Anker's popular Eufy-branded security cameras appear to be sending some data to the cloud, even when cloud storage is disabled and local only storage settings are turned on. MacRumors reports: The information comes from security consultant Paul Moore, who last week published a video outlining the issue. According to Moore, he purchased a Eufy Doorbell Dual, which was meant to be a device that stored video recording on device. He found that Eufy is uploading thumbnail images of faces and user information to its cloud service when cloud functionality is not enabled. Moore demonstrates the unauthorized cloud uploading by allowing his camera to capture his image and turning off the Eufy HomeBase. The website is still able to access the content through cloud integration, though he had not signed up for cloud service, and it remains accessible even when the footage is removed from the Eufy app. It's important to note that Eufy does not appear to be automatically uploading full streaming video to the cloud, but rather taking captures of the video as thumbnails. The thumbnails are used in the Eufy app to activate streaming video from the Eufy base station, allowing Eufy users to watch their videos when away from home, as well as for sending rich notifications. The problem is the thumbnails are uploaded to the cloud automatically even when the cloud functionality is not active, and Eufy also seems to be using facial recognition on the uploads. Some users have taken issue with the unauthorized cloud uploads because Eufy advertises local-only service and has been popular among those who want a more private camera solution. "No Clouds or Costs," reads the Eufy website. Moore suggests that Eufy is also able to link facial recognition data collected from two separate cameras and two separate apps to users, all without camera owners being aware. Moore received a response from Eufy in which Eufy confirmed that it is uploading event lists and thumbnails to AWS, but said the data is not able to "leak to the public" because the URL is restricted, time limited, and requires account login. There is also another issue that Moore has highlighted, suggesting Eufy camera streams can be watched live using an app like VLC, but little information on the exploit is available at this time. Moore said that unencrypted Eufy camera content can be accessed without authentication, which is alarming for Eufy users. There's a dedicated Reddit thread where other Eufy users are reporting the same thing happening.' -- source: https://yro.slashdot.org/story/22/11/29/2148250 Eufy products are for sale here in NZ as well.
