Stealing Encryption Keys Just by Touching a Laptop - 0 views

  • A team of computer security experts at Tel Aviv University (Israel) has come up with a new potentially much simpler method that lets you steal data from computers — Just Touch it — literally.
  • In order to victimize any computer, all you need to do is wear a special digitizer wristband and touch the exposed part of the system. The wristband will measure all the tiny changes in the ground electrical potential that can reveal even stronger encryption keys, such as a 4,096-bit RSA key.
  • in some cases, you don't even have to touch the system directly with your bare hands. You can intercept encryption keys from attached network and video cables as well. Researchers called it a side-channel attack.

  • The actual attack can be performed quickly. According to the research, "despite the GHz-scale clock rate of the laptops and numerous noise sources, the full attacks require a few seconds of measurements using medium frequency signals (around 2 MHz), or one hour using low frequency signals (up to 40 kHz)."

NSA paid $10 Million bribe to RSA Security for Keeping Encryption Weak - 0 views

  • According to an exclusive report published by Reuters, there is a secret deal between the NSA and respected encryption company RSA to implement a flawed security standard as the default protocol in its products.
  • Earlier Edward Snowden leaks had revealed that the NSA created a flawed random number generation system (Dual_EC_DRBG), Dual Elliptic Curve, which RSA used in its Bsafe security tool and now Snowden has revealed that RSA received $10 million from NSA for keeping Encryption Weak. So, anyone who knows the right numbers used in Random number generator program, can decipher the resulting cryptotext easily.

UK prime minister wants backdoors into messaging apps or he'll ban them | Ars Technica - 0 views

  • He said the Paris attacks, including the one last week on satirical newspaper Charlie Hebdo, underscored the need for greater access.

      Did they use such encryption in the attack? Would they have been caught even if encryption were not being used? what is up with that, we didn't do any better at catching thugs when they used CBs and many thugs are no smart enough to use encryption and still go uncaught.

Exclusive: Secret contract tied NSA and security industry pioneer | Reuters - 0 views

  • Documents leaked by former NSA contractor Edward Snowden show that the NSA created and promulgated a flawed formula for generating random numbers to create a "back door" in encryption products, the New York Times reported in September. Reuters later reported that RSA became the most important distributor of that formula by rolling it into a software tool called Bsafe that is used to enhance security in personal computers and many other products.Undisclosed until now was that RSA received $10 million in a deal that set the NSA formula as the preferred, or default, method for number generation in the BSafe software, according to two sources familiar with the contract. Although that sum might seem paltry, it represented more than a third of the revenue that the relevant division at RSA had taken in during the entire previous year, securities filings show.
  • RSA, meanwhile, was changing. Bidzos stepped down as CEO in 1999 to concentrate on VeriSign, a security certificate company that had been spun out of RSA. The elite lab Bidzos had founded in Silicon Valley moved east to Massachusetts, and many top engineers left the company, several former employees said.And the BSafe toolkit was becoming a much smaller part of the company. By 2005, BSafe and other tools for developers brought in just $27.5 million of RSA's revenue, less than 9% of the $310 million total."When I joined there were 10 people in the labs, and we were fighting the NSA," said Victor Chan, who rose to lead engineering and the Australian operation before he left in 2005. "It became a very different company later on."By the first half of 2006, RSA was among the many technology companies seeing the U.S. government as a partner against overseas hackers.New RSA Chief Executive Art Coviello and his team still wanted to be seen as part of the technological vanguard, former employees say, and the NSA had just the right pitch. Coviello declined an interview request.An algorithm called Dual Elliptic Curve, developed inside the agency, was on the road to approval by the National Institutes of Standards and Technology as one of four acceptable methods for generating random numbers. NIST's blessing is required for many products sold to the government and often sets a broader de facto standard.RSA adopted the algorithm even before NIST approved it. The NSA then cited the early use of Dual Elliptic Curve inside the government to argue successfully for NIST approval, according to an official familiar with the proceedings.RSA's contract made Dual Elliptic Curve the default option for producing random numbers in the RSA toolkit. No alarms were raised, former employees said, because the deal was handled by business leaders rather than pure technologists.
  • Within a year, major questions were raised about Dual Elliptic Curve. Cryptography authority Bruce Schneier wrote that the weaknesses in the formula "can only be described as a back door."

Dotcom Thanks RIAA and MPAA for Mega's Massive Growth | TorrentFreak - 0 views

  • That’s more than 10,000 files per minute….
  • The continuing debate about the NSA’s mass-surveillance is also likely to have helped Mega. Unlike other popular cloud hosting services, Mega encrypts all stored files so they can’t be snooped on. Similarly, the fact that former U.S. Secretary of State Condoleezza Rice joined Dropbox may have also had an impact according to Dotcom.

Uroburos Rootkit: Most sophisticated 3-year-old Russian Cyber Espionage Campaign - The ... - 0 views

  • The researchers claimed that the malware may have been active for as long as three years before being discovered and appears to have been created by Russian developers.
  • The two main components of Uroburos are - a driver and an encrypted virtual file system, used to disguise its nasty activities and to try to avoid detection. Its driver part is extremely complex and is designed to be very discrete and very difficult to identify.
  • The virtual file system can’t be decrypted without the presence of drivers, according to the Gdata’s analysis explained in the PDF.
  • ...2 more annotations...
  • we assume that the group behind Uroburos is the same group that performed a cyberattack against the United States of America in 2008 with a malware called Agent.BTZ
  • The attacks carried out with Uroburos are targeting government institutions, research institutions, intelligence agencies, nation states, research institutions or companies dealing with sensitive information as well as similar high-profile targets. The oldest drivers identified by the researchers was compiled in 2011 is the evidence that the malware was created around three years ago and was undetected.

Cutting the cord: Brazil's bold plan to combat the NSA | The Verge - 0 views

  • "The real danger [from] the publicity about [NSA surveillance] is that other countries will begin to put very serious encryption – we use the term 'Balkanization' in general – to essentially split the internet and that the internet's going to be much more country specific," Google executive chairman Eric Schmidt said at an event in New York this month. "That would be a very bad thing, it would really break the way the internet works, and I think that's what I worry about."

Acoustic cryptanalysis - 0 views

  • Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA. The attack can extract full 4096-bit RSA decryption keys from laptop computers (of various models), within an hour, using the sound generated by the computer during the decryption of some chosen ciphertexts. We experimentally demonstrate that such attacks can be carried out, using either a plain mobile phone placed next to the computer, or a more sensitive microphone placed 4 meters away.

    When I first read the article, I though it would take some sensitive mics but, quoting the article "Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA.

Kurt Eichenwald Claims Snowden Is A Chinese Spy And Leaks Are Just To Protect Their Cyb... - 0 views

  • And the attempts to tar and feather Ed Snowden continue. The latest is that famed reporter Kurt Eichenwald, who started attacking Ed Snowden months ago, has written up a long speculative article for Newsweek arguing that Ed Snowden has "escalated the cyber war" by giving China the necessary cover it needs to avoid reining in its own cyber attacks
  • That is, if you follow the bizarre logic here, without Snowden, Eichenwald believes that the US would have somehow convinced the Chinese to stop their cyber attack program. And, now because of Snowden, the Chinese can ignore that effort, by pointing out that the US is doing a ton of online hacking too.
  • Again, nearly everything about that statement is ridiculous. He didn't "leave all of the documents in Hong Kong." He provided heavily encrypted versions to a very small number of journalists, and then got rid of the files himself. Eichenwald takes that to mean he "left" them in Hong Kong, based on nothing, and all of this apparently means that Snowden is working for the Chinese (even though he left China pretty quickly).
