Researchers Popcorn Time Vulnerable to Significant Hack AttacksPopular file sharing and streaming service Popcorn Time contains critical vulnerabilities leaving it open to XSS attacks, files being read locally and remote code execution attacks, according to a security researcher.

The security researcher has discovered significant vulnerabilities within the popular file streaming service Popcorn Time, potentially allowing attackers to gain complete access and control of a computer connected to the service. The researcher made a comprehensive account of his findings in a blog post.

Popcorn Time has always been a target among anti-privacy companies and the MPAA (Motion Picture Association of America) and now finds itself under threat from a different adversary.

The Vulnerability

Antonios Chariton, aka ‘DaKnOb’, the researcher who discovered the vulnerability, claims to be a security engineer and researcher studying in Greece for his B.Sc. in Computer Science.

“There are two reasons that made me look into Popcorn Time,” said Chariton.

First of all, I know many people who have installed this application on their personal computers and use it, and second of all, by pure accident: I was setting up my computer firewall when I noticed the network traffic initiated by Popcorn Time.

The engineering student notes that initial concerns aside, problems really flare up when Popcorn Time initiates a “really smart” process and technique to bypass the blockades set by ISPs (Internet Service Providers) in the UK. The popular streaming service manages to do this by using the CloudFlare infrastructure as a part of its setup and connectivity process. Due to this, ISPs find it nearly impossible to block Popcorn Time purely by means of a DNS address without banning the CloudFlare website entirely.

Despite being clever in its maneuvering around the blockade, the problems coming from such a move are clear.

“First of all, the request to Cloudflare is initiated over plain HTTP. That means both the request and the response can be changed by someone with a Man in the Middle position (Local Attacker, Network Administrator, ISP, Government, etc.),” explains Charlton.

The second mistake is that there is no input sanitization whatsoever. That means, there are no checks in place to ensure the validity of the data received. The third mistake is that they make the previous two mistakes in a NodeJS application.

Furthermore, Chariton was able to engineer and initiate “content spoofing” attack which enabled him to change the title of a movie. Case in point, he gave the movie Hot Pursuit the title of “Hello World” instead.

It was at this point in time that Chariton launched an XSS attack. By injecting malicious JavaScript, the Popcorn Time client executed the code which gave him complete control of the application. He was only getting started, however.

“This essentially is Remote Code Execution on the computer that runs Popcorn Time. You can do anything the computer user could do.”

    Well into a PopcornTime session today, my computer sounded 3 alerts, and a few seconds later, a private excel file popped open, by itself. I was naturally alarmed, so I proceeded to close my network connection, and check the event log. Noticed an odd SYSTEM logon event dated a few minutes before the incident. A google update error also showed up. No VNC or similar remote-in software running. Popcorntime Desktop service was the only suspicious thing running…

The Pirate Bay is Hijacking PCs to Stealth-Mine Cryptocurrency

Published

on

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 Pirate Bay has been caught using software called Coinhive, a JavaScript library that essentially serves as a cryptocurrency miner. It basically connects to visitors’ computers to mine Monero, one of the world’s most profitable cryptocurrencies.

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

Published

on

hacker extortion bitcoin

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

Published

on

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.

// -- Discuss and ask questions in our community on Workplace.

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.
