New Tools Help You Limit Your Social Media Time

by

Facebook and Instagram are rolling out new tools designed to help manage how much time you’re spending on those two social media platforms.

On Facebook, the new feature is called “your time on Facebook,” and on Instagram, it’s called “Your Activity,” but both features do essentially the same thing.

They monitor and report on how much time you’re spending on the platform and can be fine-tuned by users to temporarily mute your push notifications.

The changes are being rolled out in an effort to address concerns that a number of groups are now raising. The concerns are about the addictive feedback loops built into social media apps. These feedback loops have been demonstrated to have a negative effect on the well being of users who get sucked in too deeply.

The new features will be rolled out to 99 percent of the users on each platform.  The company is withholding the new features from 1 percent to allow for comparative testing.

Once they become available, the new features can be found under the “Hamburger Menu,” which is the nickname for the three vertical lines at the top right-hand corner of the Facebook app.  On Instagram, the new feature can be found under the settings menu, accessible by tapping the gear icon on your Instagram profile.

It remains to be seen whether these new features will have the desired effect.  Since they have to be manually activated, odds are that the impact will be minimal. For a certain subset of users who seem not to be able to control their social media addiction on their own, it might provide just enough of a boost to make a difference.

Even if that proves not to be the case, it’s clear that the company takes the matter seriously, so we can expect to see more from them on this front in the months ahead.

Automatic Mobile Picture Sync Coming To Windows 10

by

Microsoft has made numerous ventures into the smartphone ecosystem, but so far, they’ve only been met with limited success.  This time, they’re trying something a little different.

Instead of making their own Windows-based phones, they’ve created a “Your Phone” app that syncs your phone with your PC.  The app is still in testing and is slated to be released sometime in October.

At present, while there are two versions (Android and iOS), the Android version is currently more limited than the iOS version.  The Android version works like this:  If you take a picture with your Android smartphone, it will sync automatically to your PC, allowing you to access or edit the image in something close to real time.

With the iOS version, you can surf the web on your phone, send the web page to your phone and pick up surfing where you left off.  That’s much handier, because among other things, it allows you to start watching a streaming video on your phone, then switch to a bigger screen for a better viewing experience.

In addition to the development of this new app, Microsoft is taking steps to try and bolster the popularity of its Edge browser.  Coming soon will be a biometric sign-in for Edge, which gives users a password-free method of signing into websites in hopes of keeping at least some percentage of users from switching their default browsers to Chrome, Firefox, or some other option.

At present, the changes are interesting, but not compelling.  We expect that Microsoft will continue heavily investing in integration, however, in a bid to increase its presence in the market.  Whether their latest efforts will bear fruit remains to be seen, but from what we’ve seen so far, the early versions of the Your Phone app show promise.  Kudos to Microsoft, and here’s hoping these first steps lead to even greater integration and an improvement to the overall experience down the road.

Twitter Is Getting Tough On Apps

by

Twitter has long had a reputation for being at the mercy of bots that have been used to sway public discourse and opinion.

Often, these bots are controlled via Twitter API apps that allow the authors to automate most of their actions, such as tweets, follows, and likes.

In the face of Facebook’s recent grilling before congress, Twitter has decided to take a more proactive stance, and has recently announced major changes to their policies.

The first part of the company’s statement to that effect reads as follows:

“Starting today, all new requests for access to Twitter’s standard and premium APIs are required to go through a new individual approval process.”

In addition to the newly announced approval process, the company moved decisively to cut off more than 143,000 apps they deemed to be in violation of the company’s terms of service.

The more robust approval process requires app developers to provide more information about themselves and the ultimate purpose of the apps they design.  Additionally, Twitter has put a hard cap on the number of apps that developers can create and manage, which tops out at ten.  If developers need to run more than that, they’ll need special permission from Twitter, and they’ll have to provide a compelling reason to justify the need.

Beginning September 10th, 2018, the company will be placing additional restrictions on every Twitter App which will control their use rates.

The new rate limits (per app) will be:

300 Tweets and Retweets per hour

1,000 likes per 24 hours

1,000 follows per 24 hours

15,000 direct messages per 24 hours

The company reserves the right to either remove or further restrict these limits for legitimate reasons.

On top of all that, Twitter has also modified its Twitter API support page to include an option for reporting “bad apps” that break one of the company’s policies.  According to the company, the combined effect of all of these changes should “help cut down on the ability of bad actors to create spam on Twitter via their APIs.”

While it remains to be seen how effective these changes will be, kudos to Twitter for taking action.

Bluetooth Vulnerability Allows Hackers To Access Devices

by

There’s a new Bluetooth security vulnerability to be aware of, tracked as CVE-2018-5383, and it’s a nasty one.

It’s a cryptographic vulnerability that affects firmware or operating system software drivers from a number of major vendors, including Qualcomm, Broadcom, Intel and Apple. At this point, the implication of the bug on Linux, Android, and Google are unknown.

The flaw is related to two important Bluetooth features: BR/EDR implementations of Secure Simple Pairing in device firmware and Bluetooth Low Energy (BLE) of Secure Connections Pairing in OS system software.

It was discovered by researchers operating out of Israel’s Institute of Technology. They discovered that the Bluetooth specification recommends (but critically does not mandate) that devices supporting the two features make any effort to validate the public encryption key received during secure pairing.

Since the specification is optional, it’s hardly a surprise that some vendors producing Bluetooth products do not take sufficient steps to validate the parameters used to generate public keys during the exchange.

This allows a would-be hacker the possibility of executing a man-in-the-middle attack to obtain the cryptographic key used by the device. This would give them the opportunity to not only spy on the device’s owner, but also to inject malware that could allow the hacker to take full control over the device.

SIG (the Bluetooth Special Interest Group which maintains the technology), had this to say about the flaw:

“For an attack to be successful, an attacking device would need to be within wireless range of two vulnerable Bluetooth devices that were going through a pairing procedure.

The attacking device would need to intercept the public key exchange by blocking each transmission, sending an acknowledgement to the sending device, and then injecting the malicious packet to the receiving device within a narrow time window. If only one device had the vulnerability, the attack would not be successful.”

Bluetooth SIG has now updated the specification to require products to validate public keys received as part of the public key-based security procedures. Of the manufacturers mentioned above, Apple and Intel have both released patches. Broadcom has made fixes available to its OEM customers who are responsible for providing them to end-users. There has been no word yet from Qualcomm.

Hackers May Set Their Sights On Your GPS Next

by

If you’re like most people, you probably rely heavily on the GPS function of your phone. Type in an address and your phone helpfully guides you, turn by turn, to your destination. It’s one of the most often utilized features of a smartphone, and of course, the hackers are very interested in interfering with it.

Until now though, hackers have been unable to fool humans into driving to the wrong destination by hacking their GPS, because their instructions often make no sense given the prevailing terrain features the humans are seeing on the road. For instance, nobody is going to turn left into a Jiffy Lube parking lot or a corn field just because GPS says to (unless your destination was Jiffy Lube, of course).

That’s changing, thanks to researchers from Virginia Tech and the University of Electronic Science and Technology of China.

The team has devised a way to hack into a GPS system and spoof the results well enough to fool humans, giving bogus driving directions that seem to make sense given local conditions, and as such, don’t raise red flags.

Accomplishing the task was no small feat, involving the creation of an algorithm that works in something close to real time. This along with a portable device for spoofing GPS that can be attached to the car of your target or placed in a trailing car. Its effective range is about fifty meters.

Once the equipment is in place, the algorithm crafts GPS inputs that follow the real world road network, allaying suspicion in 95 percent of the team’s test cases, while still ultimately sending the target to the wrong destination.

There are any number of ways this exotic type of attack could be used, but the two primary use cases would be to intentionally steer the target into hazardous road conditions, or to lure them to an isolated area where a physical attack could be carried out.

Unfortunately, in the months and years ahead, we can probably count on seeing both.

LTE Networks May Be Vulnerable To Hacking

by

Researchers from Ruhr-Universität Bochum and New York University in Abu Dhabi have discovered serious security flaws in 4G LTE networks that allow hackers to spy on, listen in on, intercept, and disrupt phone calls and text messages.

Given that billions of people rely on 4G LTE networks for cellphone communications, it’s a serious issue, and there are no easy fixes. So, don’t expect these flaws to be patched out of existence any time soon.  Worse still, the planned 5G networks currently in development may well suffer from the same (or similar) flaws.

Based on their research, the team was able to develop a trio of new attacks that specifically target weaknesses in the 4G LTE architecture.

One of these, dubbed “aLTEr” is a DNS spoofing attack that allows a hacker to become the “man in the middle,” intercepting communications, and gives them the ability to spoof alerts, texts, and other messages.

All three of the attacks developed by the team take advantage of weaknesses found in “Layer Two” of the LTE network.

This is the data layer that rests atop the physical channel.  Its function is to maintain wireless communication between users and the network itself, and has an organizational function that (among other things) manages how users access various resources on the network, helping to protect data via encryption and to correct errors in transmission.  Obviously, a hack that can exploit this layer could be devastating indeed.

If there’s a silver lining, it lies in the fact that these three attacks are exotic. It would be difficult for a casual or even a fairly determined hacker to execute to any real effect.  Unfortunately, it would be a much easier task for a state-sponsored group to pull off, and that’s the big fear here.

Hopefully, since 5G networks are still in the planning stages, something can be done before they’re rolled out to limit the effectiveness, or perhaps even negate these new types of attacks, but that remains to be seen.

Microsoft Edge Mobile Browser Blocks Android And iOS Ads

by

As most people know, Microsoft Edge was the company’s “reboot.”  After trying for years to patch and update their beleaguered Internet Explorer, Microsoft ultimately decided to scrap it and start fresh.  Since Edge’s launch, it has struggled to gain traction with users.

Recently, Microsoft has upped the ante, at least where Edge for iOS and Android devices are concerned.  A recent update sees the browser outfitted with a built-in ad blocker.  Prior to the update, if you wanted an ad blocking solution, you’d have to download and install it separately.  This move saves users a step, and gives you one less thing to think or worry about.

It’s a good move, but that alone is unlikely to give Edge the surge in popularity it needs to catch up with other browsers.

To provide some perspective, currently, Microsoft Edge is installed on about five million Android devices, based on stats from the Google Play Store.  Contrast that with 100 million installs of Mozilla’s Firefox, and more than a billion Chrome installations.

Those are sobering numbers that underscore just how much ground Edge needs to cover to even be playing in the same league as other popular web browsers on mobile devices.  While we don’t have statistics for installs from the Apple Store, it’s hard to imagine that they’d be any better, and, are probably a fair bit lower.

That’s not to say that Microsoft’s move wasn’t good, because it definitely was.  Anything that a company can do to cut down the number of unwanted, annoying, and potentially dangerous ads is a very good thing. Odds are that the company’s recently move will be copied by the major players in the browser world.  Even if it doesn’t boost Edge’s numbers much, that’s a win for anybody who uses the internet.  Kudos to Microsoft for making the change.

Vulnerability In Mac OS Went Unnoticed For Years

by

Researchers at Okta Security have stumbled across something big.  Recently, they discovered a flaw in Apple’s OS that would have allowed hackers to completely undermine Apple’s code signing process.

While at first glance that doesn’t sound so bad, the implications are terrifying.  In a nutshell, code signing uses cryptographic “signatures” to verify and validate code.  If code bears the digital signature, it is considered trusted.  If it’s trusted, then it’s given an automatic free pass, straight into the heart of any system.

Unfortunately, this flaw in Apple’s code signing process dates back more than a decade. It was only recently discovered, and purely by chance at that.

An extensive forensic analysis has turned up no evidence suggesting that this exploit was ever used for nefarious purposes, which is the one silver lining in all of this.

Upon discovering the flaw, Okta personnel reached out to Apple and other vendors who could have been impacted by the flaw, including tech giants like Google, Facebook and also smaller players like VirusTotal, Objective Development, Yelp, and Carbon Black.

Apple moved swiftly and has since fixed the issue, so this one can be considered a bullet dodged.

Josh Pitts, an Okta engineer, sums the issue up:

“Different types of tools and products use code signing to implement actionable security; this includes whitelisting, antivirus, incident response and threat hunting products.  To undermine a code signing implementation for a major OS would break a core security construct that many depend on for day to day security operations.”

A completely fair assessment.  Thankfully (at least in this particular case), although the issue was hiding in plain sight, it does not appear to have been exploited before being fixed.  We won’t always be so lucky.
