Spot the SFYL
Happy Friday afternoon. this week on the SFYL channel we present the following (compressed) image of some derp from twitter showing off his new "secure" Nano Ledger Bitcoin wallet.
Simon the smacktard forgot, however, to obscure the paper containing his device's seed phrase, conveniently demonstrating that some people just aren't ready to use Bitcoin yet. (archived)

Persistent Packeting Problems Plague Pizarro
An apparent DDoS attack on Pizarro ISP has left the TMSR without a portion of it's infrastructure. Affected services include Qntra, nosuchlabs, Eulora, and several blogs and logbots. The solution will likely be an amalgamation of more pythonshit and berating Republican vassals, so that services aren't brought down by a bash script while learning the finer points of systems administration ever again.

Yet another Zcash bug
Zcash is urging it's userbase to immediately upgrade their wallets and node software to apply an "important security fix". A bulletin issued by the developers released no details, but stated:
"Version 2.0.7-3 of Zcashd includes an important security fix in response to an issue that was reported to us on Friday September 13th 2019 by Florian Tramèr, Dan Boneh, and Kenneth G. Paterson. Users should upgrade their nodes to this version immediately and discontinue use of older versions. Please note that the issue does not put funds at risk of theft or counterfeiting. More details of the issue will be released in coordination with the reporters of the issue at a future date."
This latest undisclosed issue is the second reported flaw in Zcash this year alone, the first being a bug that was found that allowed one to print unlimited monies which the developers kept secret for 8 months.
UPDATE: The bug was disclosed by KMD developer Duke Leto, who stated:
“A bug has existed for all shielded addresses since the inception of Zcash and Zcash Protocol. It is present in all Zcash source code forks. It is possible to find the IP address of full nodes who own a shielded address (zaddr). That is, Alice giving Bob a zaddr to be paid, could actually allow Bob to discover Alice’s IP address. This is drastically against the design of Zcash Protocol.”

Shinohai's Saturday Shitcoin Selections 4
The lulz in this story begin in a thread for the XJO cryptocuurency on bitcointalk. This guy suggests you can "run an entire 'DNM' on the XJO blockchain" and links to a javascript page (archived) that will happily eat your private keyz and encrypt and decrypt thingz for you!
Why this is incredibly stupid:
- iGolder.com should be all you need to know, but you can also google search it if you wish.
- No mention is made of airgap setups, and the joulecoin.info site is connected to the internet when performing crypto functions.
- No mention made of layering (see above), and why you should be using 4096-bit or higher rsa keys for any comms, period.
- Cost of 51% attacks and other lulz would be near nothing for interested 3-letter agencies.
- Point #1 is honestly enough to end this discussion.
"But it's so luser friendly, everyone can do it!"
There is no scenario that exists, or shall ever exist, where "paste your key here" ever becomes proper handling of cryptographic keys, and certainly not in situations that require proper OPSEC and associated sanitation procedures. This is seriously the most retarded post I've read all year, and tardstalk produces some very brain-damaged threads.
TL;DR OP is an utter moron and you should seek advice elsewhere if you use crypto in any high-risk situations.

Official Alpine Linux Docker image found to allow NULL password for root users
Docker woes continue as security researchers discover that all "Official images" of Alpine linux (since v3.3) allow NULL passwords for the root user. This event, along with Docker Hub being hacked serve as a wonderful reminder of only running code from trusted sources and personal libraries.

McAfee flees U.S. after tax fraud allegations
John McAfee announced earlier this week that the U.S. Internal Revenue Service is allegedly charging him with felony tax evasion for 8 years non-payment of taxes, and that he will be "running his Presidential campaign from exile on a vessel dubbed "The Freedom Boat".
McAfee assured his followers on twitter that he would be releasing videos every day as long as the exile lasts, which leads the author to the conclusion that ample supplies of tinned penis, Xanax, and electronic equipment were provisioned in the freedom boat's hold before casting off. (archived)

Chinese Ethereum vulnerable to ancient bug
The NEO platform (Chinese Ethereum) was discovered to be vulnerable to the same default settings bug that caused mETH tards to have funds liberated from their nodes back in June. Chinese tech company Tencent first reported the bug, and encouraged all users to update their nodes as soon as possible, instead of correctly advising users to simply abandon the platform, and anything else remotely resembling Ethereum. Coinmarket cap lists an imaginary valuation of $532 million USD for this corn riddled steamy pile of Asian shit.

Malicious GasToken Minting in mETHereum disclosed
Quoted from the public disclosure by Level K:
This is a public disclosure of a newly discovered vulnerability. Some affected parties have already been notified in a private disclosure that was sent out on November 13th. When ETH is sent to an address, that address is able to perform arbitrary computations paid for by the originator of the transaction. This is a known vector for griefing. However, in some cases, at-risk systems such as exchanges did not put proper protections in place. GasToken, which takes advantage of the refund mechanism on storage in Ethereum, allows users to store gas when the gas price is low and receive a gas refund when the gas price is high. By minting large amounts of GasToken when receiving ETH, the griefing vector mentioned above can now be a profitable attack. Because it was unknown which exchanges did and did not have the protections in place, the private disclosure was made to as many exchanges as possible, many of which were not at risk. To our knowledge, all affected exchanges that received the disclosure have patched the vulnerability. For more information the full disclosure can be found here.
As has been documented on this blog, and formerly on Qntra (Now pretty much the BingoBoingo blog), Ethereum is a flaming tire in a shitpit that should not be used for any purpose.

Buffer overflow bug discovered in segshit address scheme.
A buffer overflow vulnerability has been discovered by satoshi labs in the bech32 address scheme, used by Segshit and introduced into Bitcoin by "Core" developer Pieter Wuille. Satoshi labs assures users of their already pwnd Trezor devices that the risk is minimal and can only result in denial of service attacks, but released a firmware update immediately after the bug was confirmed.

Eliminating malicious TLDs with regex
A discussion on Telegram this morning led to this post, I decided to preserve this handy list of regular expressions for filtering out mostly dumb and malicious TLD's. I am personally using an EdgeRouter Lite with dnsmasq for this purpose, so your mileage may vary - feel free to modify and make these better. Suggestions for changes may be sent to my email listed on the contact page, as usual non-encrypted content will be ignored.

Static address bug discovered in Ledger app
The Ledger hardware wallet team announced a serious "bug" in the Ledger Wallet Ethereum Chrome application, telling lusers to avoid using it as it generates a static address for everyone. But "Engineering is working on it" so they recommend using more Webshit, like MyEtherWallet, in the meantime while the company tries to figure out why webpages generate static addresses and bikeshed a solution.

Enumerating geth nodes for fun and profit
Step 1: Download GETH and build it inside a chroot.
Step 2: Fire up geth and wait for the ethereum database to load.
Step 3: Enumerate peers running misconfigured clients and rpc consoles by running an insecure instance yourself:
dibbuk# ./geth --rpc --rpcaddr 0.0.0.0 --rpcapi, db,eth,net,web3 --dev console
Step 4: Profit. I quickly found 22 nodes listening for the entire world on port 8545, ~60% of these were located on Chinese and other South Asian mining farms. For bonus lulz you can leverage the power of virtual shrimp mining to disrupt the network whilst you pilfer the funds from vulnerable wallets.
At the time of this post, the addresses below are confirmed to have received around $22 million USD in ETH liberated by enterprising crypto pirates, and the figures still climb despite warnings not to do this shit since March:
