Want to outfox the NSA? Generate memorizable passphrases even they can’t guess

 

Rolling dice

 

 

27 March 2015 – Micah Lee writes at The Intercept that coming up with a good passphrase by just thinking of one is incredibly hard, and if your adversary really is capable of one trillion guesses per second, you’ll probably do a bad job of it. It turns out humans are a species of patterns, and they are incapable of doing anything in a truly random fashion. But there is a method for generating passphrases that are both impossible for even the most powerful attackers to guess, yet very possible for humans to memorize. First, grab a copy of the Diceware word list, which contains 7,776 English words — 37 pages for those of you printing at home. You’ll notice that next to each word is a five-digit number, with each digit being between 1 and 6. Now grab some six-sided dice (yes, actual real physical dice), and roll them several times, writing down the numbers that you get. You’ll need a total of five dice rolls to come up with each word in your … Read more

The Sony hack is different: this time its extortion, threats and shooting the hostages. Leon Paneta’s “cyber Pearl Harbor”?

Sony hacked again
 

 Eric De Grasse, Chief Technology Officer / Gregory P Bufithis, Founder

12 December 2014 – Poor Sony. On 25 November the hackers paralyzed Sony Pictures’ computer systems, forcing the company to send some staff home while others had to use pen, paper and fax machines across its international offices. The studio could only watch while films such as musical remake Annie, scheduled for a Christmas cinema release, were leaked to file-sharing networks.

Now the hack is causing more collateral damage than just a few movies leaked onto the internet. Amongst a batch of emails made public by the hackers were several racially tinged emails about President Obama’s imagined movie tastes. And references to “a minimally talented spoiled brat” and a “rampaging ego” and a “bipolar 28-year-old lunatic”. Such language! You’d only hear that in … well, a movie.

All these things are the sort of stuff which most corporate networks have. But they just prefer they were not made public, which is exactly why the Sony hack was so embarrassing. And teams of lawyers are going through all … Read more

Those mysterious, fake cellphone towers popping up all over the U.S. : how they work

 

Fake cell towers

 

18 November 2014 – Back in August, reports started emerging of mysterious fake cellphone towers popping up all over the US. It led many to assume that there were actually strange towers of unknown purpose dotting the nation. The truth is these weren’t physical towers of any sort, but devices that were being made to trick your cellphone into thinking it was a tower.

Why would such a thing exist? There haven’t been any definitive answers, but the Wall Street Journal has reported that the answer may lie in a 7-year-old US Department of Justice program to track criminals via their cellphone, using devices attached to airplanes. The publication reported that sources wouldn’t confirm or discuss specifics about the program but did say these surveillance flights take place on a regular basis. The purpose is to track criminals and fugitives, but doing so requires a sweep that captures a lot of cellphone data from a given area. Once a suspect’s phone is found, the device releases the non-suspect phones.

Certainly news like this is going to fuel … Read more

81% of Tor users can be de-anonymized by analyzing router information, says researcher

15 November 2014 – A former researcher at Columbia University’s Network Security Lab has conducted research since 2008 indicating that traffic flow software included in network routers, notably Cisco’s ‘Netflow’ package, can be exploited to deanonymize 81.4% of Tor clients.

Professor Sambuddho Chakravarty, currently researching Network Anonymity and Privacy at the Indraprastha Institute of Information Technology, uses a technique which injects a repeating traffic pattern into the TCP connection associated with an exit node, and then compares subsequent aberrations in network timing with the traffic flow records generated by Netflow (or equivalent packages from other router manufacturers) to individuate the ‘victim’ client. In laboratory conditions the success rate of this traffic analysis attack is 100%, with network noise and variations reducing efficiency to 81% in a live Tor environment. Chakravarty says: “it is not even essential to be a global adversary to launch such traffic analysis attacks. A powerful, yet non- global adversary could use traffic analysis methods to determine the various relays participating in a Tor circuit and directly monitor the traffic entering the entry node of … Read more

What’s next, a gift shop? The National Security Agency has a side business licensing its technology

Dollar sign on keyboard with magnifying glass

 

30 September 2014 – We were at the “Defense Labs Tech Transfer” trade show in Maryland last week and stumbled across a company called TechLink, which is a US Department of Defense (DoD) Partnership Intermediary. These partnership entities are all done via government statute (check out 15 USC 3715). TechLink is based at Montana State University. The company brokers licensing agreements between DoD labs and US industry for manufacture and use of DoD inventions. These inventions involve virtually all technology fields, including medicine, software, electronics, communications, advanced materials, and energy-related technologies. There are between 100 and 150 research labs that participate under the DoD’s umbrella.

And lo and behold … the National Security Agency (NSA) is in the program (the DoD includes the NSA under its umbrella) and has been making money on the side by licensing its technology to private businesses for more than two decades. It’s called the Technology Transfer Program, under which the NSA declassifies some of its technologies that it developed for previous operations, patents them, and, if they’re swayed by an American … Read more

Snowden used TAILS, designed for internet anonymity, to protect his communications. Journalists and (certain) corporates love it.

 

Tails anonimity

He likes TAILS!

 

 

By: Eric De Grasse / Chief Technology Officer

17 April 2014 – An interesting piece from Hugh Pickens over at Dot.com on how Snowden protected his communications, using The Amnesic Incognito Live System (TAILS). I talked about TAILS in my client wrap-up post after attending the Black Hat and DEF CON hacker conferences last year in Las Vegas. TAILS is a live system that aims to preserve your privacy and anonymity. It helps you to use the Internet anonymously and circumvent censorship almost anywhere you go and on any computer but leaving no trace unless you ask it to explicitly. It is a complete operating system designed to be used from a DVD, USB stick, or SD card independently of the computer’s original operating system. It is free software and based on Debian GNU/Linux.

Here is Hugh’s piece with my comments following:

“When Edward Snowden first emailed Glenn Greenwald, he insisted on using email encryption software called PGP for all communications. Now Klint Finley reports that Snowden also used The Amnesic Incognito Live System Read more

Sochi Olympics is a cyber war zone, a master class in espionage

Sochi cyber

Sochi is “the most connected Olympics ever”

By: Eric DeGrasse, Chief Technology Officer and Gregory P. Bufithis, Founder and CEO

 

13 February 2014 – NBC took a few hits last week for a report that turned out to be almost entirely bogus on Sochi malware, Wi-Fi honeypots and sinister auto-downloads.

But as it turns out, foreign visitors to the Winter Olympics in Sochi are unknowingly wading into a cyber battlefield, say U.S. government and security experts. Large international events – packed with diplomats, business leaders and celebrities – have become honeypots for computer hackers, while Russia is home to some of the most feared cyber criminals in the world.

The Sochi games have already been plagued by fears of a potential terrorist attack and U.S. officials have warned American supporters and athletes about the dangers of attending the games, which began on Friday. But in a sign of the mounting worries over the cyber threat, the U.S. government issued guidance advising American visitors to Sochi to remove all important information from their computers and devices before they travel. They … Read more

Developer loses his single-letter Twitter handle through extortion by a hacker: the horror side of social media

 

Hackers

30 January 2014 –  Naoki Hiroshima, creator of Cocoyon and a developer for Echofon, writes at Medium that he had a rare one-letter Twitter username – @N – and had been offered as much as $50,000 for its purchase. “People have tried to steal it. Password reset instructions are a regular sight in my email inbox” he writes Hiroshima. “As of today, I no longer control @N. I was extorted into giving it up.” 

Hiroshima writes that a hacker used social engineering with Paypal to get the last four digits of his credit card number over the phone then used that information to gain control of his GoDaddy account. Most websites use email as a method of verification. If your email account is compromised, an attacker can easily reset your password on many other websites: “By taking control of my domain name at GoDaddy, my attacker was able to control my email.” 

Hiroshima received a message from his extortionist: “Your GoDaddy domains are in my possession, one fake purchase and they can be repossessed by godaddy and never seen Read more

German TV: Edward Snowden says NSA is also involved in industrial sabotage

NSA industrial espionage

 

26 January 2014 – The National Security Agency is involved in industrial espionage and will take intelligence regardless of its value to national security, Edward Snowden has told a German television network. A lengthy interview was broadcast tonight by German public broadcaster ARD TV. It quotes Snowden as saying the NSA does not limit its espionage to issues of national security and citing the German engineering firm Siemens as one target.

“If there’s information at Siemens that’s beneficial to US national interests – even if it doesn’t have anything to do with national security – then they’ll take that information nevertheless”, Snowden said. The interview was recorded in Russia where Snowden has claimed asylum. Snowden also told the German public broadcasting network he no longer has possession of any documents or information on NSA activities and has turned everything he had over to select journalists. He said he did not have any control over the publication of the information, ARD said.

Reports that the NSA monitored Chancellor Angela Merkel’s mobile phone have added to anger in Germany, which … Read more
