iMessage No more Reliable?

According to some reports published this Monday, a team of IT researchers from John Hopkins University has worked out a way to crack open the files sent through the iMessage app. However, it was not at all easy to do so. They spent two whole months in it. The team, under the supervision of Professor Matthew Green made it possible to find out the 64-bit encryption key to open an encrypted image stored on the iCloud.

For stealing the key from the encrypted information carrying it, they developed a software which behaved like an Apple server. By doing so, they were able to get the key from the encrypted transmission.

Once they got the key, they entered it in the iPhone which was able to decrypt the image and it was visible.

Apple’s Action

This process could only target an iPhone with an older version of the iOS running on it but Professor Green said that by modifying the method of attack a little, they could even attack the iPhones with a newer operating system. Apple made immediate efforts and released the iOS 9.3 which is not vulnerable to this sort of attack. According to one of the team members Ian Miers, Apple responded to them very quickly and took serious steps to make the phones safer.

Companies like apple cannot implement the security reforms instantly as they have to put the new systems to test in a number of different expected circumstances. Keeping that in view, the response of Apple towards this research is really appreciable.

Does Apple Have a Weak Security?

The fault that the research team has pointed out is , in no way, a fault with the Apple’s encryption algorithm but just an implementation error, said Bailey, one of the officials of Apple’s security research wing. It just enables you to guess one of the digits in the key and once you do that you can only get the access to a single message, image or a video stored on the phone. To access all the data, you will have to repeat the process for every single item which is virtually not possible. Also, the effort needed to access the data using this process, it is not a viable option for mass-scale hacking.

The iPhones are still way better than the phones which do not use encrypted transmission and this flaw is not something that can affect the routine users as it took two months to crack a single image which means it will require a duration of time longer than the age of universe itself to access all the data on the phone.

Myth of Encryption

Recently, the struggle between Apple and FBI regarding the decryption of some iPhones has gained a lot of public attention. The FBI had declared the encryption on iPhones and Macs to be impenetrable but the Hopkins researchers have shown that it is possible to find flaws in it. Apple has some of the best cryptographic engineers working with them, still the encryption can be broken it makes the other low-end systems totally obsolete when it comes down to encryption.

The New “In Budget” iPhone Se Repair Geekz 

Apple, the California based company is known for manufacturing some of the most high-end phones, tablets and computers. Delivering the best specs and style, the Apple products have always been outrageously expensive and only the elite can afford them. But, March the 21st 2016 marked a change in the history of Apple products when Tim Cook announced a remake of the famous iPhone 5s under the name of iPhone 5 se.

The phone will be available in more than a hundred countries around the globe by the end of March and will be priced at a mere 399 US Dollars. Though this phone is not an absolutely cheap device but when compared to the existing Apple phones, the price is a quite low one. Before this phone no iPhone was ever priced below 900 Dollars as the release price tag.

Even though the phone is priced half as much as the new iPhones generally are, the company has continued its legacy of not compromising the quality. According to Apple,s press release earlier this Monday, the phone will have all the specs of the latest iPhone 6s. It will be equipped with the same camera, touch id, operating system and the same Apple A9 chip. However, it will be in the size of iPhone 5, the 4 inches screen. This is because of two reasons, firstly, the iPhone 5 size was highly appreciated in the global market and the customers loved the design of this phone, secondly, this will help Apple keep the price of the handset lower.

The handset will have the fastest-to-date Apple A9 chip and the latest iOS 9.3. The rear camera will be a 12 mega-pixel unit capable of capturing 4K videos and 12 MP pictures simultaneously. Moreover the resolution and pixel density is also at par with the latest iPhone 6s. The only feature from iPhone 6s not included in this phone (obviously besides the 4.7 inches touch screen of the 6s0 is the pressure sensing touch or the 3D touch of the iPhone 6s. This phone will also be enabled to respond to the famous ‘hey siri’ command even when it is locked. Noise cancellation will also be improved by using a dedicated Mic for canceling any noise of the surroundings and make the voice communication even more clear. One more amazing feature that this device is going to have is the introduction of a new and improved fingerprint sensor which is certified by the mainstream digital currency service providers like PayPal.

Pre-orders for the phone have already begun. It is intended to target the market portion which previously couldn’t afford to have an iPhone.

The phone will be available in gold and rose gold color besides the usual Grey and white colors which were available in the 5s.

We hope this is a good start from Apple in making technology available to all the classes of the society and not only the wealthy.

What To Expect From iPhone 7, Repair and Fix in Elmhurst, villa park, oak brook, lombard

What To Expect From iPhone 7 

We’re just few months away from the Apple’s next phone. Probably, this is going to be the most important smartphone Apple has ever released. Like many other people, you must be wondering what plans Apple has for iPhone 7 and what you can expect. Even though rumors have suggested so many things, here are some of the most feasible ones that you should expect. iPhone 7 will be a piece of cake to repair in elmhurst il

  1. The iPhone 7 release is going to be in September 2016

If you’ve been keen enough, you must have noticed that apart from iPhone SE, every remaining iPhone is often released in September. For this reason, we don’t think it’s going to be different with iPhone 7. In fact, many companies that will be supplying components of this phone are already ramping up production that fits in the release date in September. Oak Brook will be the place to take your iPhone Repair Geekz

  1. The iPhone 7 will not have a 16GB storage option

Of course, 16 GB is not enough space for a smartphone especially when you take into account all the apps you use and all the content you create. With the introduction of iPhone 7, it can be very surprising if Apple offers a 16GB version as they did with the current version iPhone 6s. Apple knows that it will only make sense to you and other users if iPhone 7 comes with a minimum 32GB of memory. In fact, many analysts have concluded that with the high-res content this phone will generate and many more apps that users will install, iPhone 7 can only have a minimum of 32GB of storage.

  1. The price of the iPhone 7 is likely to stay the same

Over the years, the cost of iphones has remained relatively consistent. Therefore, you should expect the new Apple’s handset to launch at around the same price as their current handset – iPhone 6s. This therefore means that the asking price for the iPhone 7 will likely start at around £500 to £550, while its Plus variety will likely sell at around £600 to £650.

  1. The iPhone 7 will give you slightly a longer battery life

According to the images leaked by the Chinese site Digi.tech.qq.com of what the battery of Apple’s new handset could be, we can conclude that the phone will have a better battery life. Precisely, the image shows what could be the battery of this new smartphone and it has a capacity of 7.04 watt-hours (Wh), which is in fact, larger than the current Apple’s iPhone 6s with a battery capacity of 6.61Wh.

  1. The iPhone 7’s specs will be very good

Reports from reliable sources suggest that the Apple’s next smartphone could come with 3GB of RAM, which is actually the largest amount ever shipped in any iPhone. Concerning processor, rumors suggest that the new handset will use an A10 chip and most likely, it will be made by TSMC, Samsung or even a combination of the two.

Best Upcoming Smartphones That You’ll Want To Wait For In 2016

Are you about to commit to a 24-month smartphone contract? Well, before you invest in any of the handsets you see in the market, you should first read this list of 2016’s best upcoming phones to ensure that you won’t regret later why you didn’t wait. So, if you’re ready to splash out right now, this list of Android smartphones might convince you to wait.

  1. Galaxy Note 6

The release date of the amazing Samsung’s Galaxy Note 6 will be officially announced very soon. Right now, rumors have reached fever pitch. With rumors of Android N, USB Type-C, a massive 6GB of RAM and a frankly shocking 256GB of storage, the Samsung’s Galaxy Note 6 is set to be nothing less than a beast. In case that doesn’t tickle your fancy, then the whispers of a 5.77in, 2K Super AMOLD display should actually do. These are just but some of the most juicy details about the Galaxy Note 6.

  1. Apple iPhone 7

According to many analysts, the Apples  new handset is going to be more revolution than evolution. You should expect iPhone 7 to be a totally redefined handset and come with a raft of new amazing features.

Even though Apple has managed to keep most of their new handset details, we have also managed to uncover more details about the phone. For instance, chances are that there would be an iPhone 7 Pro, which might actually mean that the Pencil is making its way to an iPhone.

  1. Sony Xperia X and Xperia X Performance

Just like many other people and companies, we never expected Sony to kill off the Xperia Z completely and I bet this news has actually shocked you too. It’s interesting to note that Sony is replacing its flagship phone with a pair of new ones. The new handsets look millimeter-identical but they use different Qualcomm processors. Precisely, the Sony Xperia X uses a mid-range Qualcomm Snapdragon 650 and because we have managed to get hold of one, we’ve tested and found out that the performance of this handset is more than what you can ask for.

  1. OnePlus 3

If you’re on budget and you want a premium smartphone, you would want to wait for few months for the OnePlus 3 to be released. We have actually confirmed that it will be released in September 2016.

By the look of things, OnePlus 3 is going to be special. With a Snapdragon 820 processor, 4GB of RAM, 64GB storage and 5.5 –inch display, this handset might just be the most affordable flagship you’ve been waiting for because rumors suggest that it will sell at around £215.
