How to Avoid the Stagefright Vulnerability in Android

Published

on

Android phones occupy the biggest share of cell phones in the market. At around 80%, Android devices are the most widely used phones worldwide. However, Android is susceptible to an appalling vulnerability that could cause serious damage to a user’s data as well as his device.

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

There is a minor but albeit dangerous glitch in the Android system installed on all Android devices, which grants attackers and hackers an easy passage into a user’s device. This small yet utterly dangerous vulnerability is called Stagefright.

What is Stagefright?

Stagefright is a component in Android devices which is used in multimedia handling. The component is granted system permissions in most Android running devices, which is only one level below root access. This fact alone is enough to open peoples’ eyes about the dangerous threat of Stagefright on Android devices.

All it requires is a little exploitation on the attacker’s behalf, and the user’s Android device is left hanging in the balance. The most astounding fact about the reality of Stagefright’s seriousness is the simplicity and effortlessness of the method to exploit it.

How does a Stagefright Attack Works?

Stagefright component of Android devices is generally exploited via MMS or multimedia messages. 95% of Android devices download incoming multimedia messages automatically in the user’s inbox without prompting him or her for the download. Upon downloading of the multimedia, all it takes for the attack to take effect is that the user opens the message. It is that simple to exploit the vulnerability.

What’s more is that there are other, equally simple, ways to go about triggering Stagefright attacks in Android devices. The fact that Stagefright is a multimedia handling component makes even web pages, that have multimedia looking to exploit Stagefright, viable entry points into the user’s device. If the user simply visits the web page that has that particular multimedia file, it’s game over.

How to Avoid Stagefright Vulnerability in Android

Although it is really simple to trigger a Stagefright attack, there are no fool-proof strategies to guard your device against it. Nevertheless, there are a couple of methods which can help you with defending yourself to a certain degree. They are:

  1. Disable the auto-download multimedia option in your device to ensure that multimedia messages containing Stagefright isn’t downloaded to your device automatically. It is also smart to check the receipt of all multimedia messages. You never know if a friend’s phone has been compromised by Stagefright.
  1. Developers could come up with a security patch to tackle this problem. Although this seems a straightforward and long-term solution, it is hardly so. Google Play Store does not host or allow anti-virus applications to run with system permissions. Coming up with an app or security patch that could help prevent Stagefright would mean revamping the policies and structure of the Google Play Store. Although this has been done on some occasions for necessary security patches, it just might prove to be too much work. There are reports, however, that high-end devices can expect a security patch release for Stagefright soon.

Conclusion: What can you do?

Stagefright is a really dangerous threat to all Android devices. The first thing you need to do is to be aware of the threat. The two ways discussed above can help you in preventing your device from Stagefright to a certain extent. There are applications which can test whether your device is at risk of Stagefright. You can simply run the tests and then decide whether to go for the methods discussed above.

Spectre And Meltdown Madness: What It Means For Ethereum

Published

on

To anyone who talks in terms of a cryptocurrency bubble, consider the following fun facts. In the short period of a few days following the bombshell announcement of Meltdown and Spectre, crypto prices responded in the following manner:

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

Bitcoin +18%

ETH +41%

Litecoin +30%

// -- Become a yearly Platinum Member and save 69 USD and get access to our secret group on Workplace. Click here to change your current membership -- //

In my view, this is clear evidence of a market that is responding rationally to information coming from responsible sources. To appreciate what all the noise is about you must appreciate what Meltdown and Spectre are and why they present a danger to the big companies providing cloud storage for the corporate world.

Once this is clear, then you will better appreciate why Ether’s 41%+ short-term price spike left the others in the dust. But first lets dig into the Meltdown and Spectre situation.

The Secret Got Out

 On January 3 the secret about a new class of security vulnerabilities leaked out to the public. Not only was this seriously bad news but the leak also gave hackers advanced notice before anyone could begin to fix the twin problems.

The degree of seriousness is in the fact that almost all major microprocessor chips are vulnerable. This opens the door to hackers stealing information from personal as well as cloud services.

Researchers claim that Meltdown can be fixed with a patch. Shortly thereafter about every major player announced their patch. But there are two issues here. Will the patches fully solve they problem?

Casting A Cloud Over The Cloud

When a corporation becomes a cloud customer, even the largest share machines with other customers. This is the basic flaw in the centralized structure of cloud storage. Contrast this with the decentralized structure of blockchain technology and you begin to appreciate the force behind the sudden price spike in cryptocurrencies that we highlighted above.

Even though security tools and protocols are designed to separate customers date, the recently discovered Meltdown and Spectre flaws still leave serious vulnerabilities.

Meltdown, hackers could rent space on a cloud service, just like any other business customer. Once they were on the service, the flaw would allow them to grab information like passwords from other customers.

Secondly, reports on cloud services like Amazon, Google and Microsoft claim that it creates as much as 30% slower computation speeds. That clearly won’t make for happy customers.

Jerky NetFlix

Virtually everyone reviewing the situation believes individual computer users are the least vulnerable. That may be true. Hackers are in the hunt for the biggest prize and that would be the big three cloud companies. But how do you think families are going to react if their Netflix stalls and buffers every few minutes?

In the final analysis, the Meltdown flaw affects virtually every computer chip fabricated by Intel in use today. You are talking about 90% of the Internet and business world. But Meltdown is just one flaw.

Spectre is the other flaw and this one is the more insidious of the two. There is no known fix. Intel, AMD and others have claimed how complex a project it would be for hackers to breech the Spectre vulnerability. That is pretty hollow comfort. After all, hasn’t the FBI security been breeched. Those guys were supposed to be airtight.

Boom Days For Blockchain

In so many ways, last year marked a tipping point in the spread and acceptance of blockchain technology. The uses for Bitcoin are probably best gauged by its record $20,000 price in December. For Ethereum, it may have been marked by the formation of the Enterprise Ethereum Alliance (EEA) in February and rise to over 300 members at year-end.

No sooner has 2018 begun that the Meltdown and Spectre flaws created unexpected excitement for investors in cryptocurrencies. If I were a software salesman out of work, I would be sending my resume to every crypto company offering to peddle their blockchain. It could be the easiest job since selling web design services in 1995.

The Ethereum platform with its smart contracts is not the only crypto capable of addressing this newly uncovered opportunity created by Meltdown and Spectre. You can safely bet this will attract many players and for good reason, today’s blockchain technology is a long way from fast enough for mass adoption. Blockchain security may be a step or two better in it present form than cloud storage, but it has its security issues as well.

Building the Ethereum Moat

 EEA founder Jeremy Millar is clearly a brand ambassador for Ethereum. He believes that CEOs hear the chatter about blockchain and are pre sold not having a clear picture what can be accomplished or the money saved using this technology. The important thing is for IT departments to have a respected brand to attach to their recommendations.

The EEA seeks to connect and inform and through this pioneering process spread the gospel of Ethereum. So far this is beginning to build a brand franchise for Ethereum.

The EEA is the largest blockchain body and is committed to using open-source Ethereum technology for enterprise blockchain solutions. EEA expects to see great advances in these areas in 2018 with Ethereum technologies.

It also helps when Wall Street banks uncover the potential for billions in savings on the trading desks through the applications of the Ethereum platform.

So, if you though the last year held plenty of excitement, the Meltdown and Spectre flaws promise to make this year every bit as much fun.

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.

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

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.

Breaches

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.
