Cyberpunk Builds Bitcoin Wallet That Even Apple Can’t Ban

Posted on by

“Coinpunk lets you house your Bitcoin wallet on your own server that can then be accessed from any other device, including an iPhone. The mobile web interface comes complete with a QR code scanner — the preferred way to handle Bitcoin transactions here in the real world. You can spend bitcoins not only online but with restaurants or shops that accept the digital currency.  If you can bring yourself to trust them, you do have the option of running a Coinpunk server with a local hosting company or in the Amazon cloud. And Coinpunk does offer its own hosting service for those who are willing to trust Drake himself.”

Bitcoin market price app, ‘Bitcoin Alarm,’ is carefully cloaked malware

Posted on by

“The desktop Windows application sends price alerts by SMS to a mobile phone. But closer examination of its code turned up several suspicious traits that indicate it may try to steal the virtual currency, wrote Kenny MacDermid, a research analyst with security company Arbor Networks.  Tucked inside Bitcoin Alarm is a script that checks whether security software from Avast is running. If so, it stays quiet for 20 seconds.  An encrypted file inside Bitcoin Alarm turned out to be a remote-access Trojan called NetWiredRC, which can be used to steal login credentials and, in this case, bitcoins, he wrote.”

SpareCoins: The Bitcoin Wallet In Your Browser

Posted on by

“Using a Desktop Wallet sucks if you’re sending a small amount of Bitcoins. Opening one in another window feels clunky, and syncing with the Blockchain can take a day. SpareCoins is a Chrome Extension that can be opened with one click, or CTRL+SHIFT+K. This makes sending Bitcoins around the web much easier.  Every week, another online Bitcoin Wallet will get hacked. SpareCoins, however, does not have a central point for attackers to target. Your private keys are encrypted and stored inside your browser, rather than an unsecure remote server. They can be backed up at anytime, and clearing your cache won’t delete your keys.”

BTC-e: Our Recent Issues Were Caused By a Surge In Users

Posted on by

“BTC-e is anything but transparent and it uses third-party banking services, keeping its name out of official records. At least one of the banks involved in the process is located in the Czech Republic, the BTC-e site references Bulgaria in its SEO descriptions, the founders are Russian programmers Aleksey and Alexander who honed their skills at the Skolkovo tech park and the BTC-e managing company is based in Cyprus.  With all that in mind, it is understandable that investors were concerned by the issues.  Luckily BTC-e got in touch with CoinDesk to reassure the public that it is a legitimate operation.”

Don’t Let Amazon Steal Your Data

Posted on by

“Jeff Bezos is happy to take your money even if you buy under a false name, pay via a credit card in the name of a New Mexico LLC with anonymous members and have items delivered to an anonymous mail-drop address.  In other words, there’s no reason you can’t operate online using an alter ego – another ‘self’ or, preferably, more than one. All it takes is a few simple steps: pseudonyms, anonymous LLCs for your credit-card accounts, mail drops and so on. That way, even if the Feds raid Amazon or Google, they won’t be getting your real data.  For the purposes of government snooping on the servers of the Big Data companies, you’ll remain an anonymous alter ego in the crowd.”

Kryptokit Launches as Dark Wallet’s Biggest Rival

Posted on by

“As a Chrome extension, the Kryptokit wallet is an open-source project. Users can create their bitcoin addresses by moving their mouse around the screen. This, along with a random number generator, creates each user’s address.  The system also has another tab, for secure messaging. This uses GPG (the open-source version of the Pretty Good Privacy protocol developed by Phil Zimmerman) to secure messages between its users.  The GPG key can be used to encrypt messages that are sent to other Kryptokit users. There are some key differences between Kryptokit and Dark Wallet. One feature that the Dark Wallet team is reportedly discussing is a trust-less mixing service.”

Bitrated: You Can No Longer Say Bitcoin Has No Consumer Protection

Posted on by

“Bitrated’s solution to consumer protection is in some ways an old one: escrow. Rather than a customer sending a payment to a merchant directly, the customer sends the payment into escrow, and the funds are released from escrow only when the customer confirms that they received the product or service. However, Bitrated makes one major addition to the model: multisignature transactions. Rather than the customer sending money directly to a trusted escrow agent, the customer sends the money to what is called a ‘2-of-3 multisignature address’ constructed using the customer, merchant and escrow agent’s public keys.”

French agency caught minting SSL certificates impersonating Google

Posted on by

“Rekindling concerns about the system millions of websites use to encrypt and authenticate sensitive data, Google caught a French governmental agency spoofing digital certificates for several Google domains.  After Google brought the certificates to the attention of agency officials, the officials said the intermediate certificate was used in a commercial device on a private network to inspect encrypted traffic with the knowledge of end users, Google security engineer Adam Langley wrote in a blog post published over the weekend. Google updated its Chrome browser to reject all certificates signed by the intermediate authority and asked other browser makers to do the same.”

“We cannot trust” Intel and Via’s chip-based crypto: FreeBSD developers

Posted on by

“The revelations are having a direct effect on the way FreeBSD will use hardware-based random number generators to seed the data used to ensure cryptographic systems can’t be easily broken by adversaries. Specifically, ‘RDRAND’ and ‘Padlock’—RNGs provided by Intel and Via respectively—will no longer be the sources FreeBSD uses to directly feed random numbers into the /dev/random engine used to generate random data in Unix-based operating systems. Instead, it will be possible to use the pseudo random output of RDRAND and Padlock to seed /dev/random only after it has passed through a separate RNG algorithm known as ‘Yarrow.'”
