RollJam, a contraption put together by a security researcher for less than $50 can unlock car and garage doors at will by exploiting digital keys, also known as rolling codes.
Hacker season is officially underway.
A contraption comprising of two radios, a microcontroller and a battery, all put together for less than $50 by an independent researcher can unlock vehicle doors and garage doors at will by taking advantage of a vulnerability in their keyless entry systems, Wired reports.
Samy Kamkar, the independent researcher who devised the radio device is set to reveal details of the gadget at the DefCon hacker conference in Las Vegas.
A Vulnerability the Car Industry Should Take Notice of
“Every garage that has a wireless remote, and virtually every car that has a wireless key can be broken into,” claims Kamkar.
Here’s how RollJam works:
- One-time authentication codes, also known as ‘rolling codes’ are quickly intercepted by RollJam when placed near a vehicle or a garage and the owner hits the button on his key.
- These rolling codes are crucial as they’re the authentication codes transmitted between the car and the key with each lock and unlock. Significantly, there are no timeouts on these codes.
- RollJam capably intercepts and captures the rolling code and jams the signal to ensure the car never receives it.
- The owner will inevitably try the key again and this time, RollJam quickly transmits the first rolling key, unlocking the vehicle.
- This automation happens so quickly that the owner is fooled into thinking that the second key-press worked whereas in actuality, RollJam has also acquired the next one-time rolling key, which a hacker can conveniently use at a later time to unlock the vehicle.
“So when you are walking towards your car, you hit the unlock button — because it’s jammed, the car can’t hear it, however my device is also listening so my device hears your signal (and removes the jamming signal because it knows what to remove). Now I have a rolling code that your car has not yet heard.”
Vehicle security based on “rolling codes’ is used in most modern vehicles including trucks and cars’ keyless entry feature. Moreover, the same mechanism is also used in modern garage door openers, rendering millions of vehicles and garage doors vulnerable to a simple hack.
Kamkar claims he has tested the device successfully on vehicles manufactured by Nissan, Ford, Toyota, Lotus, Volkswagen, Chrysler and Cadillac vehicles.
RollJam is intended to bring attention to outdated security measures used by car manufacturers, Kamkar says.
“This is throwing the gauntlet down and saying, ‘here’s proof this is a problem,’” adds Kamkar. “My own car is fully susceptible to this attack. I don’t think that’s right when we know this is solvable.”
The technology for better security already exists, notes Kamkar. Two-factor authentication with codes that expire in seconds are already in use with consumer technology like Google Authenticator and SecurID by RSA.
Meanwhile, millions of keyless entries use security systems with codes that never expire, making your own car and garage doors (likely!) vulnerable.

The Pirate Bay is Hijacking PCs to Stealth-Mine Cryptocurrency
For the second time in as many months, The Pirate Bay has been caught mining cryptocurrency on your computer without consent. The torrent platform was actually test-driving cryptocurrency mining in your browser – no doubt a lucrative revenue stream.
The Pirates Are At It Again
The news was later confirmed by Bleeping Computer, which reported that,”The Pirate Bay, the internet’s largest torrent portal, is back at running a cryptocurrency miner after it previously ran a short test in mid-September.”
Estimates indicate that the scheme has earned the pirates a total of $43,000 over a three-week period.
Users had no way to opt their computers out of being test-driven by the torrent network. Back in September, The Pirate Bay got away by telling people it was just a test. The site’s owners cannot use the same excuse this time around.
CoinHive advises websites to let their visitors know their browser is being used to mine cryptocurrency.
“We’re a bit saddened to see that some of our customers integrate CoinHive into their pages without disclosing to their users what’s going on, let alone asking for their permission,” the company said.
The good news is most ad-blockers and antivirus programs will block CoinHive, given its recent abuses. That means not all visitors of The Pirate Pay were being used as a conduit for mining Monero.
Monero Joins Global Crypto Rally
The value of Monero (XMR) shot up nearly 8% on Friday, and was last seen trading at $94.17. With more than 15.2 million XMR tokens in circulation, the total market cap for Monero is $1.4 billion, according to CoinMarketCap. That’s enough for ninth on the global cryptocurrency list.
Twelve cryptos have now crossed the $1 billion valuation mark. A handful of others have made their way north of $500 million.
Coders Safeguard Vulnerable Ethereum Wallets Following Security Breach
Ethereum suffered large-scale security breaches last week after anonymous hackers targeted vulnerable wallets in the network, resulting in the loss of tens of millions of dollars. However, it didn’t take long for a volunteer group of coders to “rescue” the funds in 500 at-risk wallets before the same attackers could get to them too.
White Hat Group Takes Charge
The so-called White Hat Group showed initiative by “rescuing” the funds using the same techniques the thieves employed to compromise $32 million USD worth of ether from three multi-signature wallets. As of Monday, the White Hat Group of ethical hackers was in possession of $86 million worth of ether and an additional $122 million in tokens.
Tokens are digital assets that are sold during an Initial Coin Offering (ICO) fundraising event. They have proven to be extremely popular.
Tens of millions of dollars worth of ether and tokens have already been returned to their owners. The White Hat Group says it will issue full refunds by the end of July.
Blockchain-based trading platform Coindash was also breached last week, resulting in the loss of more than $7 million worth of ether.
Security Breaches Nothing New in Crypto World
For all its benefits, cryptocurrency has been vulnerable to several high-profile security breaches. Last summer, Hong Kong-based Bitfinex was the target of a major attack that resulted in the theft of around $70 million worth of bitcoins. In response, the exchange announced a controversial plans to “socialize” its losses among all users. Each Bitfinex trader was docked 36% as a result.
Bitcoin prices declined sharply following the attack, stopping what had been a blistering summer of gains.
Ethereum Enterprise Alliance
For anyone doubting the potential of the ether, take a look at the list of companies participating in the Enterprise Ethereum Alliance (EEA). The EEA is a forum that connects Fortune 500 companies, startups and academics with ethereum subject matter experts. The EEA is made up of multinational banks and some of the world’s biggest technology companies.
The forum has made cyber security a top priority, according to a May 22 press release. In the release, companies like Infosys, Mitsubishi UFJ Financial Group, Synechron and others expressed their intent to contribute to the future of ethereum’s security.
Hackers Only Need Seconds to Figure Out Card Details
Experts from Newcastle University in England has found that hackers only need six seconds to figure out the card number, expiry date, and security code for a Visa debit or credit card by simple guesswork, according to a report from The Telegraph.
According to figures from the Office of National Statistics, in the U.K. the number of bank account fraud cases reported up to June 2016, from the beginning of the year, amounted to over 2.3 million.
The researchers found that all that a hacker needs is a computer and an Internet connection. It is believed that hackers simply utilize what is known as a Distributed Guessing Attack enabling them to get around security features that help prevent online fraud.
By using the Distributed Guessing Attack, the system was unable to detect multiple attempts made by hackers.
Process of Elimination
As such, within a matter of seconds hackers were able to determine the correct information on a person’s card by a process of elimination.
Only recently Tesco bank account customers were subjected to hacking after criminals were able to gain access to their accounts. It is believed that these hackers may have used the Distributed Guessing Attack to siphon money from peoples’ accounts.
Payment Cards Remain Vulnerable
Unfortunately, even though Visa debit and credit cards remain popular and convenient forms of payment, they remain vulnerable as well.
And hackers know this, which is why reports of online card fraud are becoming more prevalent in today’s technologically-advanced world.
Visa states though:
The research does not take into account the multiple layers of fraud prevention that exist within the payments system, each of which must be met in order to make a transaction possible in the real world.
However, while this may be the case, it seems something is amiss if cybercriminals can simply determine a person’s card details in six seconds through guesswork.
Bitcoin to the Rescue?
The digital currency bitcoin, however, may provide an answer to this problem.
As a type of digital currency that is held and created electronically with no central bank governing it, bitcoin is considered the cash of the Internet.
Due to its popularity more people are turning to it instead of fiat currency.
It was recently reported that Sweden is considering the issuance of its own digital currency, ekrona, in an effort to address the significant decline of the use of cash in the country.
Whereas India has announced that digital currency will become the new normal in the country as it attempts to reduce the amount of cash transactions with the banning of its biggest banknotes, the Rs 500 and Rs 1,000.
While these are just a few instances of how bitcoin is revolutionizing how we see money, many are quickly catching on to how safe and effective bitcoin is as a form of payment in a world where hackers are gaining easy access to a person’s Visa debit and credit cards.
