Two-factor authentication can seem very useful for securing your essential accounts from intruders. However, more and more hackers have been getting into accounts that use text messages for two-factor authentication. Look into these reasons why you should switch over the type of two-factor authentication you operate away from text messaging.

Routing Messages

When you’re holding your phone close to you, you might be thinking that an intruder will have to get into your phone by getting you to install malware. For the past couple of years, though, intruders have been more clever into how they get into mobile phones. They can do this by going directly to your mobile phone carrier.

The way they do this is by first finding some personal details about you. These can be as complicated as your social security number or as simple as the address you live on. From there, they call up your phone carrier.

Depending on the phone carrier, they can be easily convinced that you’re locked out of your mobile device, and you need your number transferred to a separate phone. Intruders can accomplish this by giving up their details and paying a small fee. If it goes successfully, an intruder will have full access to any phone calls or text messages coming your way, with no way to stop them until you’re able to call your phone carrier again. This all is why you shouldn’t ever use text messaging for your two-factor authentication.

Notifications

Sometimes, an intruder might not even be far away to the point where they can be looking at your phone screen in public. Depending on your mobile device settings, you might have notifications popping up with security codes on any screen of your device. Intruders can come up with a plan to get a security code this way.

For example, you might be live-streaming a game on your phone to the internet. Intruders will use this to their advantage by logging into your account online and checking your stream for when the phone notification appears. After that, they can log in to your account and do enough damage before you even have the chance to change the passwords on your accounts. Notifications are just another reason why you shouldn’t be using text messaging linked to your two-factor authentication.

Understanding if Your Device Has Been Hacked

From social sites to banking, smart devices are increasingly becoming part of most people’s daily lives. Unfortunately, they are also exposing them to data snatchers, popularly known as hackers. The hackers may gain access to a device in many ways, but we will discuss how to know when that happens.

Receiving Random Pop-ups

Random pop-ups are not annoying, but they are among the most popular signs that a device got hacked. If one is getting random pop-ups from their browser, something has compromised their device with adware. Adware is popular with hackers when trying to force someone to view certain websites to drive revenues through viewership.

Draining Battery without Any Reason

If one notices that a device battery is quickly losing power for no reason, that is a sign that it has malware. This sudden loss of battery power is due to malware or spy-app that is operating from the background. The spy-app uses a lot of battery power to scan the device and transmit it to the hacker.

Poor Performance

One may notice that their device is suddenly crashing all the time or loading web pages much slower. When such happens, first try shutting down the machine, and take notice of what happens. If the device has gotten hacked, it may fail to shut down correctly or not shut down at all.

One can also notice slowed functionality of some operations, such as making calls or receiving text messages. Such things shouldn’t take long unless the device has a spy-app.

Increased Data Usage

Another indication of a compromised device is the exceptionally high data usage. The usage may be a result of a background running app communicating to a third-party.

Contact List Gets Call and Tests That the Owner Didn’t Make

When a device gets hacked, the hacker leaves the malware in the gadget and may use the contact list to spread it. One’s email list, text messages, or instant messages may transmit the malware to his contact through messages with links or attached files. Check out for complaints from the contact list about notifications that they supposedly received.

The Device’s Settings Change

If the hacker physically accesses a device, they may manually change its settings. For instance, one may notice that their device Bluetooth is on, despite them not switching it on. Such settings change maybe a sign of malware interfering with the device settings to spread it to other devices.

There are many ways to know when a device has gotten hacked. To prevent losing data or money, always take preventive measures. For example, one can run a malware scanner on their device.

Technology’s Impact on Hiring and Recruitment

Burgeoning tech has been laying claim to multiple industries from real estate to insurance, and more recently technology began to disrupt our hiring and recruitment tactics. In the digital age, it’s no surprise that how people find openings and apply for jobs changed. Now the vast majority start their searches online with sites like Linkedin and Indeed, but the actual interview process itself is also changing. Portfolios all take place online, interviews originally happen via video and personality diagnostics are standard.

One Way Interviews

Interviews are typically two-sided. A few business representatives interview a potential hiree, and while the hiree wants to impress the business, it’s also a chance to field questions and get to know each other.

Tech poses to change that with the rise of video interviews. As Dave Lee describes, “Traditional interviews with an interviewer and interviewee could go by the wayside, too. Rather than a two-way interaction, job candidates will upload video responses to interview questions. New technology will detect non-verbal cues such as those facial expressions and tone while eliminating human bias.” Brands like Red Bull already hopped on board with video interviews. This added step tests the applicant’s ability to think on their feet while also working through potential red flags or false starts eliminating wasted time for recruiters. Then, once the cream rises, formal interviews can take place. As Rajpreet Heir highlights, “Not only does digital interviewing allow candidates and employers to connect earlier in the interviewing process, it also saves time and money. A study by OfficeTeam revealed that 63% of companies are using video interviews vs. 13% from 2011.”

Analytics and Diagnostics

Personality diagnostics are also increasingly popular as an inexpensive means to gauge fit and placement within a larger company. As Chamanpreet Singh says, “Data is critical in the digitisation of recruitment. It allows you to determine the effectiveness of any strategy implemented and will enable HRs to develop future recruitment strategies based on the metrics and measurements received. This data will give an insight into channels that can work for your company which means cutting down on time and expenditure.”

Building a Business-Savvy Brand

It’s important to remember that if you can find them, potential recruits can also find you. As a result, recruiting in the digital age requires a larger emphasis on companies’ online brands. People want to understand the company culture they throw themselves into. Show personality, but also be sure the image you portray is accurate. Top talent is going to do their research, and if your digital presence is non-existent or inaccurate, they won’t want to work with you. As Rachit Jain says, “Building a healthy working culture and employer brand is getting more important day by day. But most importantly, employers and recruiters have to adapt and move to the modern recruiting technology faster.”

Pro Tips for Keeping Your Crypto Safe

Staying safe online is harder than ever, and the stakes are even higher when there’s money involved. Someone can easily make a fake Twitter account using your profile image and copied bio, and in the time it takes you to report the account, another person might have mistaken it as you and already transferred money to them. It’s an easy mistake to make if you’re not being vigilant, and unfortunately, as soon as you report one account, another can pop up in its place. To keep your cryptocurrency safely in your possession, these suggestions will help you do that:

Know the attack vectors.

You can’t protect yourself if you don’t know what you’re up against. Fake sites have gotten very good at mimicking their targets – so good that if you don’t double check the URL, you might not even know the difference.

Use strong passwords.

This might seem like a no-brainer for digital natives, but it’s worth repeating. Don’t use words like street names, birthdays, or song lyrics. But don’t randomly keyboard smash, either, because a) you’re not as random as a computer generator and b) you want to be able to keep track of your keystrokes, or else risk not being able to sign into your account anymore.

Use cold storage.

All “cold storage” means is offline and unattached or “air gapped,” which is to say, unconnected to your home network in any capacity. You can do this by removing the network card from your computer, or by buying a hardware wallet. If you’re feeling really cautious, you can cover your computer’s camera and microphone, and even remove all electronic devices from that room.

Test everything.

Make small transactions beforehand to make sure everything works. Never manually type in a url – it’s too easy to make a mistake that way, and could cost you a lot of money in errors. Copy/paste and QR codes are your best friends, though make sure your scanning app is reliable! Test your seed phrase on your hardware wallet; test the MD5 checksum before and after you load the SD card on your air gapped computer. Check everything. You can never been too careful.

Store your seed phrases in multiple places.

Your seed phrase is the string of 24 words that you can derive a private key from. You want to make sure your seed phrase stays secure at all times. For some, this means writing the seed phrase down on paper, in which case, it is recommended you make two copies and store them in separate places. SD cards are also an option, though they don’t tend to last more than five years and can be wiped by an EMP bomb. A combination of analog and digital methods is the best option. For the most cautious, they will split the seed phrase in parts and store those parts separately. If you do this, be sure to remember the order they go in, or else lose access to seed phrase altogether.

Plausible deniability.

Most simply, this means be able to keep some of the data hidden. Like in the physical world, you don’t want to advertise how much money is in your bank account, so don’t do it in the digital world, either. Also look into using multiple wallets rather than storing all of your currency in the same place.

Keep your environment safe.

Require two-factor authentication, and educate others on how to stay safe. Help the community at large by reporting fake sites and teaching the less tech-literate about why strong passwords are important. Not only are you keeping yourself protected, but you are also protecting others and paying that forward.

Is Blockchain the Face of the Next Google?

When we discuss blockchain, conversations usually surround the tech’s association with cryptocurrency, security and investing. In reality, this new tech is multifaceted and shows major implications for nearly every industry. When it comes to blockchain and cryptocurrency, news outlets can’t stop reporting on the potential promise. That being said, now people are asking big questions like could blockchain actually be the developments needed to create a search engine capable of overtaking google?

Google dictates much of our online searches with “nearly 80 percent of desktop and 95 percent of mobile searches” taking place on the program. That being said, a plethora of alternatives exist. The problem, of course, is that while some people use these tools, most cater to specific niche audiences, because Google has become a Goliath that many of the Davids of search engines aren’t ready to conquer. Enter blockchain. Given its clout in the tech field, many think it could be the answer to building a search engine capable of overcoming Google.

In terms of basic rising user trends, more people results in more reported problems, and Google users experience their fair share of flaws. Privacy remains the primary point of contention with centralized search engines. As BitClave describes, “With centralized search engines, your search data is recorded, your IP address is logged, and tracking cookies are used by centralized search engines to create a digital profile of you so they can target you with ads. Even worse, there’s no way to voluntarily opt out of this invasion of your privacy, and every time you type a keyword into a centralized search engine, you’re giving up information that puts you at risk.” Blockchain acts as the poster-child for privacy and discretion though. While heavily regulated given its infrastructure, the system manages to maintain a level of anonymity for its users.

Now the question becomes, how do we combine blockchain’s private network with a computing system that has the strength of Google? One program still in beta testing called Presearch, thinks they may have found the answer. As Shivdeep Dhaliwal explains, “Using Blockchain technology, Presearch plans to enable users to personalize their experience while staying in control of their data.” The company also incentivizes the switch, rewarding users who change from Google to their program with cryptocurrency coins based on their use. Of course, this still isn’t a perfect system. Questions have arisen about whether hackers may take advantage of the rewards and hack into other user profiles in order to gain more coins once they max out since users are limited to 8 coins a day.

The Presearch program focuses on decentralizing the search engine model, rewarding users for their contribution. As a result, they hope to build a more transparent and unbiased ranking, a problem that Google has made headlines for, for years. Of course, the idea of using blockchain to create a more effective model is one thing and actually doing it another thing.
