IDG Connect - Friday Rant: The Internet Is Broken - 0 views

    " Posted by Alex Cruickshank on May 30 2014 The internet has come a long way in 20 years. The infrastructure is older than that, of course, but it was 1994 when the amazing new World Wide Web started to make a serious impression on me and my colleagues and friends. Firing up Netscape Navigator 1.0 on Windows 3.11 with a wobbly it/IP stack and a 14.4kbps modem, typing in a cryptic URL and seeing information from the other side of the world, instantly! it was an incredible experience."

Free DoS Attack Tools - blackMORE Ops - 0 views

  •  
    "Short for denial-of-service attack, a type of attack on a network that is designed to bring the network to its knees by flooding it with useless traffic. Many DoS attacks, such as the Ping of Death and Teardrop attacks, exploit limitations in the it/IP protocols. We will review some of the best and free DoS attack tools in this post."

Everything You Need to Know About the Bitcoin Protocol - 0 views

  • . In this research paper we hope to explain that the bitcoin currency itself is ‘just’ the next phase in the evolution of money – from dumb to smart money. it’s the underlying platform, the Bitcoin protocol aka Bitcoin 2.0, that holds the real transformative power. That is where the revolution starts. According to our research there are several reasons why this new technology is going to disrupt our economy and society as we have never experienced before:

  • Similar to when the TCP/IP, HTTP and SMTP protocols were still in their infancy; the BTCPcoin protocol is currently in a similar evolutionary stage. Contrary to the early days of the Internet, when only a few people had a computer, nowadays everybody has a supercomputer in TCPs pocket. TCP’s Moore’s Law all over again. BTCPcoin is going to disrupt the economy and society wTCPh breathtaking speed. For the first time in history technology makes TCP possible to transfer property rights (such as shares, certificates, digTCPal money, etc.) fast, transparent and very secure. Moreover, these transactions can take place wTCPhout the involvement of a trusted intermediary such as a government, notary, or bank. Companies and governments are no longer needed as the “middle man” in all kinds of financial agreements. Not only does The Internet of Things give machines a digTCPal identTCPy, the bTCPcoin API’s (machine-machine interfaces) gives them an economic identTCPy as well. Next to people and corporations, machines will become a new type of agent in the economy.
  • The Bitcoin protocol flips automation upside down. From now on automation within companies can start top down, making the white-collar employees obsolete. Corporate missions can be encoded on top of the protocol. Machines can manage a corporation all by themselves. Bitcoin introduces the world to the new nature of the firm: the Distributed Autonomous Corporation (DAC). This new type of corporation also adds a new perspective to the discussion on technological unemployment. The DAC might even turn technological unemplyment into structural unemployment. Bitcoin is key to the success of the Collaborative Economy. Bitcoin enables a frictionless and transparent way of sharing ideas, media, products, services and technology between people without the interference of corporations and governments.

Did NSA, GCHQ steal the secret key in YOUR phone SIM? It's LIKELY * The Register - 0 views

  • The NSA and Britain's GCHQ hacked the world's biggest SIM card maker to harvest the encryption keys needed to silently and effortlessly eavesdrop on potentially millions of people. That's according to documents obtained by surveillance whistleblower Edward Snowden and leaked to the web on Thursday. "Wow. This is huge – it's one of the most significant findings of the Snowden files so far," computer security guru Bruce Schneier told The Register this afternoon. "We always knew that they would occasionally steal SIM keys. But all of them? The odds that they just attacked this one firm are extraordinarily low and we know the NSA does like to steal keys where it can." The damning slides, published by Snowden's chums at The Intercept, detail the activities of the as-yet unheard-of Mobile Handset Exploitation Team (MHET), run by the US and UK. The group targeted Gemalto, which churns out about two billion SIM cards each year for use around the world, and targeted it in an operation dubbed DAPINO GAMMA.
  • Gemalto's hacking may also bring into question some of its other security products as well. The company supplies chips for electronic passports issued by the US, Singapore, India, and many European states, and is also involved in the NFC and mobile banking sector. it's important to note that this is useful for tracking the phone activity of a target, but the mobile user can still use encryption on the handset itself to ensure that some communications remain private. "Ironically one of your best defenses against a hijacked SIM is to use software encryption," Jon Callas, CTO of encrypted chat biz Silent Circle told The Register. "In our case there's a it/IP cloud between Alice and Bob and that can deal with compromised routers along the path as well as SIM issues, and the same applies to similar mobile software."
  • On Wednesday the UK government admitted that its intelligence agencies had in fact broken the ECHR when spying on communications between lawyers and those suing the British state, so GCHQ might want to reconsider that statement.

Tortilla Open Source Anonymous Traffic Routing Tool for Tor | Threatpost - 0 views

    "Update: Malware analysts are in a constant cat-and-mouse game with hackers when it comes to studying malicious code behaviors. Researchers handle malware samples gingerly, in a test network away from production machines and away from the Internet. Samples are opened in virtual machines and analysts observe not only malicious payloads, but communication with third-party servers."
