Living Room / ROCA - 5 year old vulnerability can break RSA
« on: October 17, 2017, 03:39 PM »
A crippling flaw in a widely used code library has fatally undermined the security of millions of encryption keys used in some of the highest-stakes settings, including national identity cards, software- and application-signing, and trusted platform modules protecting government and corporate computers.

The weakness allows attackers to calculate the private portion of any vulnerable key using nothing more than the corresponding public portion. Hackers can then use the private key to impersonate key owners, decrypt sensitive data, sneak malicious code into digitally signed software, and bypass protections that prevent accessing or tampering with stolen PCs. The five-year-old flaw is also troubling because it's located in code that complies with two internationally recognized security certification standards that are binding on many governments, contractors, and companies around the world. The code library was developed by German chipmaker Infineon and has been generating weak keys since 2012 at the latest.

I just discovered, which, with a single command, allows you to set up your Linux installation to block ads.

After that, you can configure your router to use Pi-hole as your DNS to block all ads on every device on your network. Combined with a VPN into your home network, this allows even your mobile device(s) to browse ad-free from anywhere.

I found it super simple to set up on my Odroid C1 (a Raspberry Pi 2-like device) and look forward to seeing it in practice more.

The "base" unit of measurement in Ethereum is called Ether, which can be broken down to the eighteenth decimal place into single units called Wei. While it is useful for machines and programs to be able to deal with such small amounts, it can be difficult for the human mind to deal with such significant differences in terms of numbers. For example, if you were to think of these values in terms of US Dollars, then a Wei is to a penny what an Ether is to 1 Quintillion (1,000,000,000,000,000,000) dollars. Not only that, but these denominations have been named in honor of people whose research and ideas cryptocurrency is built upon, so the names for the denominations are relatively obscure and unintuitive to the average person.

For example: I need to send 300 Finney to someone. The gas cost for the transaction is 2 Shannon (Gwei) (per unit of gas). It will cost 21,000 units of gas. But what does this all mean in terms of Ether?

Additionally, while we like to talk and deal with units such as Ether or Finney since they're closer in value to other currencies we're used to transacting in, Ethereum itself handles all the numbers internally in terms of Wei (as an integer). So if you start to get involved with programming smart contracts for Ethereum, you often need to enter values in Wei.

So I made this app that allows you to type in a value in any of the various Ethereum denominations and it will display the equivalent value in the other denominations.

If you use Ethereum and you find this tool useful, donations of ETH or ERC20 (or similar) Tokens are greatly appreciated: 0xDC201825Cc536b9541734eb975Cd6333840C736d

DC Gamer Club / Outlast + Whistleblower DLC free on Humble Store
« on: September 21, 2017, 08:38 PM »
As the title says, Outlast plus the Whistleblower DLC are free on the Humble Store for the next day or so. And be sure to redeem your keys on Steam before October 7th, too.

In July, the Director of the World Wide Web Consortium overruled dozens of members' objections to publishing a DRM standard without a compromise to protect accessibility, security research, archiving, and competition.

EFF appealed the decision, the first-ever appeal in W3C history, which concluded last week with a deeply divided membership. 58.4% of the group voted to go on with publication, and the W3C did so today, an unprecedented move in a body that has always operated on consensus and compromise. In their public statements about the standard, the W3C executive repeatedly said that they didn't think the DRM advocates would be willing to compromise, and in the absence of such willingness, the exec have given them everything they demanded.


EFF no longer believes that the W3C process is suited to defending the open web. We have resigned from the Consortium, effective today. Below is our resignation letter

General Software Discussion / CCleaner contained malware for one month
« on: September 19, 2017, 12:55 AM »
Around 2.27 million users of Piriform's popular CCleaner security app have been advised to update the application—a result of sophisticated hacker-hidden malware. Discovered by researchers at Cisco's Talos division, hackers are thought to have run code from a remote IP address using a backdoor.

The short of it is that v5.33 contained malware so be sure to update to v5.34 which seems to fix the problem.

N.A.N.Y. 2018 / NANY 2018 Mug/T-Shirt Design Competition
« on: September 12, 2017, 05:53 PM »
Hello all artists and designers!

Each year, DonationCoder runs a programming challenge called New Apps for the New Year, or NANY. It's a celebration of programming and encourages coders to provide some new app, tool, utility, game, etc., to the world, free of charge. Anyone who submits an app to NANY is rewarded with a commemorative mug or t-shirt which has a fun design on it. There has always been a standard design, which looks like this:

NANY Standard Design.png
(Click to enlarge)

But there has often been an alternate design to set that NANY's event apart from the others. In addition to seeing all the new apps being released each year, one of my favorite things about NANY is seeing the fun new alternate design each year. As someone who has participated in a few of the past NANY events, I have to admit that having an alternate design I liked has often been a motivator for me to submit something. Sadly, the past couple of years there haven't been alternate designs. So after seeing mouser express his desire for an alternate design this year, I approached him with the idea of holding some kind of competition to solicit submissions. He agreed, and this is the result.

This design competition aims to make sure we have an alternate design to be offered alongside the traditional design. Some of the details are still being hashed out, but here's what we have so far:

  • We want to find one alternate design for the NANY 2018 mug and t-shirt.
  • The design must include:
    • The words "" (without quotes)
    • The words "NANY 2018" (without quotes)
    • Our mascot, Cody (the bird)
  • Artists can submit as many entries as they would like by the deadline (tentatively set for December 1, 2017). These entries can be rough drafts/sketches.
  • We will hold a forum poll, wherein previous NANY coders get to choose the winning design.
  • The winner of the design competition will receive $75, and gives us permission to use the design. (We may require the design to be licensed CC BY-SA 4.0 or similar. Exact license TBD.)
  • If the winning design was just a sketch, the winner must submit a finished design before the end of NANY 2018 (potentially to be used in apps, the website, and of course for the mugs/t-shirts), which is January 1, 2018.
  • We may award $25 as runner-up prizes for other images if they can be used for other website purposes.
  • The father of Cody, nudone, will receive $75 since we have used his images (and the likeness of Cody) for all these years without paying him anything.

The design for the mug must be 1662x600 or larger. We can use the same image for the t-shirt, or a larger, square image. Artists should feel free to make a larger image with the t-shirt in mind which can then have less important parts cropped out to fit the dimensions for the mug.

Some previous designs and other art to give artists ideas:

If you have any questions, comments, submissions, or other feedback, this is the place for it. Please let me know if I left anything out or if I can assist in any way.

DC Gamer Club / Free Game on Humble Store - The Walking Dead: Season 1
« on: September 07, 2017, 08:11 PM »
The Walking Dead: Season 1 (by Telltale Games) is currently 100% off (redeemable on Steam) from the Humble Store for the next day or so.


This was originally a response to the Crashplan thread.

Has anyone here heard of some of the new(ish) decentralized/distributed cloud storage services, such as Storj or Sia?

They're cheaper than, e.g., Amazon S3, Google Cloud, Microsoft Azure, etc., and have additional features such as privacy, since your data is broken up into little chunks, encrypted, and distributed across the drives of many different "storage farmers" who rent out their disk space.

Sia seems to be a lot cheaper, but also seems a bit more convoluted to set up. Storj is more expensive (than Sia, but still cheaper than Amazon S3, etc.) but appears to be fairly simple to set up. They've even partnered with FileZilla so now Storj services are built in to the latest version of FileZilla. Storj also offers 25GB free for 12 months. They might be worth looking into if you need cheap cloud storage.

Full disclosure: I recently learned about these services and decided to allocate some of my HDD space for a Storj farm to get an idea of how it works. So I get paid a few dollars worth of the Storj cryptocurrency each month for renting out some space on my HDD. As far as I know, there's no way to choose which farmer your data gets sent to, so there's no way for me to directly benefit from referring anyone. That said, there's a chance that if you do use Storj, some of your data could end up on my HDD and I will be compensated for renting out my space to you.

I also tried to rent out some space using Sia, but as I said, it is more convoluted. It requires you (as a "farmer") to put up some collateral and I wasn't sure enough that I had things configured correctly to want to risk losing my collateral.

I recently discovered Etcher, which is a nice utility you can use to easily write disc images to USB drives and SD cards. It's great for things such as bootable Linux Live OSes or flashing an SD card for an IoT/SBC device.

Some notable features:

  • It prevents you from overwriting your internal drives.
  • It verifies that the media was flashed correctly.
  • It's cross platform, working on Linux, Windows, and MacOS.
  • It's portable. No need to install.

Check it out at

Discovered by Joern Schneeweisz, a security researcher for Recurity Labs, the flaw relies on tricking users into cloning (copying) a source code project via an "ssh://" link.

Social engineering not necessary to exploit the flaw

Schneeweisz says that a URL in the form of "ssh://-oProxyCommand=some-command" allows an attacker to execute commands on the computer of the user performing the clone operation.

"While it might be tricky to convince a user to clone a repository with a rather shady looking ssh:// URL, this attack vector is exploitable in a more sneaky way when it comes to Git submodules," Schneeweisz explains.

"It is possible to create a Git repository that contains a crafted ssh:// submodule URL. When such a repository is cloned recursively, or the submodule is updated, the ssh:// payload will trigger," the researcher added.

Patches to fix the vulnerability should already have been released, so be sure to update your version control to protect yourself from this vulnerability.

An interesting article on how trivial it is to link "anonymized" data to real people, and how Web of Trust probably shouldn't be trusted.

In August 2016, a data broker received a phone call from a woman named Anna Rosenberg, who worked for a small startup in Tel Aviv. Rosenberg claimed she was training a neural network, a type of computing architecture inspired by the human brain, and needed a large set of browsing data to do so. The startup she was working for was well-funded and purchasing the data wouldn't be a problem. But given the number of brokers out there, Rosenberg wasn't going to purchase the browsing data from just anyone. She wanted a free trial.


After receiving her free trial data [...] Eckert's first task with the data was to find out if her browsing data was included in the dataset. To do this, she queried the data for the URL linked with her company's login page, which generates a unique ID for each employee.


Although it turned out her browser history wasn't in the data set, by querying the data for her company's login page Eckert discovered that a number of her colleagues were in the data by matching the unique login IDs from the company's page to the individuals.

With this information, Eckert would've been able to see her colleagues' entire browsing history for the last month. One of the colleagues included in the dataset was a close friend of hers, and she reached out to him to let him know that she had his browsing history. The question she had was which browser plugin was collecting and selling this data.

To answer this question, Eckert had her colleague delete one browser plugin every hour until he disappeared from the live data. On the seventh plugin, he disappeared. This suggested that the plugin collecting and selling his browser data was, ironically enough, called Web of Trust, which offers "free tools for safe search and web browsing."

DC Gamer Club / Jotun: Valhalla Edition free on Steam & GOG
« on: July 14, 2017, 03:36 PM »
For a limited time you can claim Jotun to your Steam account or to your GOG account.

I've never played it so I can't attest to whether or not it's any good. But at this price, it's worth looking into (or just claiming "just in case").

You can now download the Ubuntu command-line interface (AKA shell) from the Windows Store, with some caveats.

The store listing appears, but it says it's only compatible with Windows 10 version 16190.0 or higher, which is only available as part of the Windows Insiders program at the moment.

Even still. This is an interesting and useful development for anyone who ever fired up a VM just to run a few Linux commands.

DC Gamer Club / Steam Summer Sale 2017 - June 22 through July 5
« on: June 24, 2017, 08:54 PM »
It's summer, and that means another Steam summer sale!

Aside from the nice discounts on many games, Steam is also running a promotion where you can do a few "quests" each days to earn sticker packs. I don't really see the point of the stickers or sticker packs, but I guess they know all about how driven people are by worthless digital collections.

Speaking of worthless digital collections, you can also earn Steam Summer Sale Trading Cards through various activities on your Steam account during the sale.

But anyway, I've been using Steam less and less over the past few years, mostly because of the glut of crap that has gotten on the storefront through Greenlight (which has recently been discontinued), and also because I've begun to appreciate the value in DRM-free games more and more (hooray for GOG!). That said, it might be fun if people use this thread as an opportunity to recommend good games to each other that are worth picking up during the sale.

DC Gamer Club / Extra Copy Giveaway: Wasted
« on: June 13, 2017, 01:57 PM »
DC member p3lb0x has an extra game key for Wasted and is willing to give it away to someone who would make use of it.

I have the key to hand out to the first person to ask for it, under the following conditions:

  • You must be an established member of DonationCoder.

That's it, really.

It's a humble bundle key, which I believe is redeemable on Steam.

Living Room / RESOLVED: Please help me figure out this CD
« on: June 07, 2017, 10:38 PM »
UPDATE: I've come to the conclusion that the CD is corrupt (Cyclic Redundancy Check errors), and have told the owner to try to get a new copy from the original source. Original message below.

Someone handed me a CD, telling me it contains photos of her 5-year old daughter's ballet class. She says her computer won't read it and asked if I could get the photos off of it for her.

When I put it in my computer it tries to read it for several seconds but then gives up. It doesn't show up as having anything inserted in it.  Here's the mystery: I opened up the Disk manager to see what it would reveal, and it's showing this:

Big CD.png

Media: CD-ROM Disc
Size: 1.1GB (1,073,741,312 bytes)
Volumes: 1.1 GB Unknown

The CD itself is labeled as a Philips 700 MB/80 min 52x speed CD-R. I'm sure most of those details about the CD itself are unimportant, but I included them just in case.

So... how can a 700 MB CD have a 1.1 GB partition on it? Is there any way I can salvage the data from the disc, or is it a lost cause? Any suggestions or troubleshooting steps I should take to try to get the disc to read properly?


The man was ordered to give his iPhone password to police. He insists that he did. But the password he gave them doesn't work. So the judge is holding him in criminal contempt.

A Hollywood man must serve 180 days in jail for refusing to give up his iPhone password to police, a Broward judge ruled Tuesday — the latest salvo in intensifying legal battles over law-enforcement access to smart phones.

Christopher Wheeler, 41, was taken into custody in a Broward Circuit Court, insisting he had already provided the pass code to police investigating him for child abuse, although the number did not work.

“I swear, under oath, I’ve given them the password,” a distraught Wheeler, his hands handcuffed behind his back, told Circuit Judge Michael Rothschild, who earlier in May found the man guilty of contempt of court.

While the headline does sound scary, maybe it's a technicality. Maybe the case is that since he provided a password that didn't work, the judge thinks he's lying and holds him in contempt. Perhaps if he had simply refused to provide any password at all, citing the 5th amendmentw, the judge would not have held him in contempt of court.

DC Gamer Club / Mount & Blade - 48 hour giveaway on GOG
« on: May 19, 2017, 11:43 AM »
For the next ~44 hours from the time of this post, you can get Mount & Blade for free (and DRM free!) on GOG. And all the other Mount & Blade games are 75% off as well.

Supposedly M&B: Warband is the best of the bunch.

I've played quite a bit of M&B (the original) but haven't really played any of the expansions/sequels.

And here's a roundup of some mods for the game which should give you plenty to do:


Dungeons 2 is free on the Humble Store for the next 2 days as part of their Spring Sale. Note that this purchase has to be redeemed to a Steam account within a couple of weeks. I don't remember the exact timeframe.

Eador: Genesis is free on GOG for the next 2 days to celebrate the launch of Gremlins, Inc from the same company.

I think this is a pretty clever new email service.

First of all, Lemon features end-to-end encryption so that no one--not even Lemon engineers--can read the content of your emails, except of course you and the intended recipient. No scraping the content of your emails to better advertise to you or gather personal/private information. In fact, there are no ads in your email period. "The way it works is that the passphrase you use to unlock your emails is not saved anywhere / on our server and therefore even our engineers cannot read your emails. (Don't forget your passphrase!)"

Secondly, Lemon is powered via IPFS[1] and Ethereum's blockchain technology. This allows Lemon to be decentralized. Meaning there is no central server to be hacked. No single point of failure that can prevent you from being able to access your email. In fact, there is no server at all. "Your emails are safe in pretty much any scenario you can imagine, from natural disaster to alien invasion."

Thirdly, you can still use it to email your mom. Lemon will translate your email from the IPFS version and communicate with the recipient's SMTP server (or vice versa for incoming email from non-Lemon accounts). "When emailing people that are outside of Lemon Email service, we have [an] additional security layer so that third party email services cannot read or decrypt your emails."

The future of the internet, using P2P/distributed technologies such as IPFS and Ethereum, is developing into something really amazing. :Thmbsup:

More info about Lemon:

The one thing that puzzles me is they claim it's all "at the price of one cappuccino a month" but the pricing plans page says it's $20/mo. That sounds like one expensive cappuccino to me!
