Are You Handing Over Your Passwords To Hackers?

Written By Sahani Brothers on Sunday, July 7, 2019 | 11:31:00 PM


Are You Handing Over Your Passwords To Hackers?


Tips To Keep Your Passwords Safe

Data theft and hacking is the nightmare that torments all corporate enterprises and entrepreneurs in today’s technology-driven business ecosystem. Therefore, password protection has assumed greater significance than ever. Passwords are the first line of defence against any malicious intent hackers, and it is imperative to use strong passwords to keep your computers and mobile devices safe from falling prey to hacking or identity theft.

Unfortunately, this is where poor password management practices adopted by employees bleed the organizations repeatedly. According to the Verizon Data Breach Investigations Report, more than 70% of employees reuse passwords at their workplace.  The report further states that 81% of hacking-related breaches are either due to stolen and/or weak passwords.

The Dropbox data breach, which resulted in a massive 60 million user credentials being stolen, had started with an employee reusing a password at work.  Ignoring the password security tips not just compromises the security of an individual user’s data but might also result in severe consequences for the organization. This could lead to a financial as well as credibility loss to the company.


To help you address this concern, enumerated below are 7 password protection best practices that enterprises use to defend themselves from cyber-attacks.

1.Don’t choose a weak password:

It’s shocking to see that many people still use passwords such as “123456” or their name 1234. Such passwords make the devices more vulnerable to cyber-attacks. A strong password is a combination of alphabets, numbers, upper case, lower case and special characters. A long password is always considered to be safer by cybersecurity experts.

2.Use multifactor authentication:

With the increasing number of online services emails, internet banking, a lot of sensitive information of users is now stored in the mailbox. Only a password does not prove to be sufficient to secure these accounts, which demands the use of an additional layer of security. Many companies nowadays encourage their users to go for a secondary layer of security, which can be an OTP generated through call or SMS.

3.Create Password Blacklist:

Hacking attempts become successful mostly due to easy to guess passwords.  Hackers use a database containing most frequently used password formats to target online users. Organizations should educate the employees to maintain a password blacklist and avoid using mostly used password format.

4.Different accounts need different passwords:

Keeping the same passwords for multiple accounts may provide convenience to users but it opens the door for hackers. Often, users keep the same password for their personal and official accounts like Outlook, CRM etc. which many times bring the entire organization’s data at risk.

5.Apply Password Encryption:

Encryption provides advanced protection to online accounts even if the password is compromised. Reversible encryption or applying only one-way encryption are common tactics for password security. However, this method will be of no use, if the hackers manage to gain access to the organization’s database. End-to-end password encryption is still regarded as the best technique of password security.

However, these methods are ineffective—if an attacker obtains the password database, it would not be difficult to crack and compromise the passwords it contains. Instead, the best practice is to consider end-to-end encryption that is non-reversible.  Storing a password in plain text is considered to be the most dangerous practice as it’s easily accessible by cybercriminals.

6.Consider a password manager:

A password manager is a most widely used tool these days by users who have multiple accounts to manage and it’s cumbersome on his or her part to do the same. The tool keeps a complete track of the multiple user name and passwords kept. Users just need to load these passwords only once and use a master key to lock the same. So only the master key needs to be remembered by the user.

7.Arrange Regular Employee Training:

Training employees regarding various cybersecurity guidelines reduce data breach incidents considerably. It has been observed that more often data leaks occur in organizations when a curious employee clicks on phishing links received via emails. There is a need to periodically educate employees regarding the latest phishing prevention tips and password best practices.

Hackers May Glean Your Password By Listening To How You Type On Your Phone


Hackers may glean your password by listening to how you type on your phone – The Denver Post

W
hat if scammers could learn your password not from a massive cyberattack or taking control of your device, but from listening in as you type?

That’s the startling premise of a recent study by researchers at Cambridge University and Sweden’s Linköping University who were able to glean passwords by deciphering the sound waves generated by fingers tapping on smartphone touch screens.

Malicious actors can decode what a person is typing by using a spying app that can access the smartphone’s microphone, according to the study, which was first reported by The Wall Street Journal. “We showed that the attack can successfully recover PIN codes, individual letters and whole words,” the researchers wrote.

A passive, sound-based attack could be executed if a person installs an app infected with such malware. “Many apps ask for this permission and most of us blindly accept the list of demanded permissions anyway,” the researchers wrote. Attackers also could also provide their target with a smartphone to which the malicious app was pre-installed.

The researchers designed a machine-learning algorithm that could decode vibrations for specific keystrokes. Among a test group of 45 people across several tests, the researchers could correctly replicate passwords on smartphones seven times out of 27, within 10 attempts. On tablets, the researchers achieved better results, nailing the password 19 times out of 27 within 10 attempts.

“We found the device’s microphone(s) can recover this wave and ‘hear’ the finger’s touch, and the wave’s distortions are characteristic of the tap’s location on the screen,” the researchers wrote. “Hence, by recording audio through the built-in microphone(s), a malicious app can infer text as the user enters it on their device.”


In this Jan. 17, 2012 file photo, a person tries a smartphone loaded with Google Wallet at the National Retail Federation in New York.



 The experiment ran on an Android application that allowed participants to enter letters and words on two LG Nexus 5 phones and a Nexus 9 tablet, according the paper. As the participants tapped in the passwords, the app recorded audio through the devices’ built-in microphones. To simulate a real-world environment, the researchers had participants enter passwords at three locations at a university, with different levels of background noise: a common room where a coffee machine was used, a reading room with computers and a library.

The study had not yet been peer reviewed, according to the report, or been published, but it is available online through a website maintained by Cornell University for academic research.

To guard against such attacks, the researchers suggested, smartphone makers might consider installing a switch that would allow users to shut off the microphone. Another option, they said, is to simply make it more obvious when the microphone is on, by flashing a light or an icon on the screen.

The research fits into a broader study of security vulnerabilities that exploit a device’s built-in sensors — such as cameras and accelerometers — to extract personal information from users without their knowledge.

Oracle, The Hardware Company

Written By Sahani Brothers on Thursday, November 1, 2018 | 4:25:00 AM

For all of the dazzle of its rapidly evolving software portfolio, which includes a self-monitoring and self-patching database that also configures itself, as well as numerous cloud applications, Oracle has begun showing its credibility as a hardware vendor.
Hardware has commoditized and will not return to the prominence it had in the early days of the tech era. However, commoditization brings new opportunities simply because price-performance numbers work better. Under Oracle's tutelage, hardware has found a disciplined and important niche supporting software's expanding demands.
All of this started well before Oracle became involved in hardware with its purchase of Sun Microsystems. In the very earliest days of computing, the central computer did everything including controlling peripherals, which took up a lot of expensive cycles.
Then slowly the box housing the CPU became crowded with processor and memory-based controllers for everything from disk drives to displays. In the process, computing got faster and more versatile, in part because the CPU was doing less and could stick to its knitting.

Risk Reduction

What Oracle introduced at OpenWorld 2018 is in some ways akin to installing a controller or a graphics engine, but this time the added processing power is outside the box in multiple racks. Just as with those earlier refinements, new requirements have been driving new approaches to IT. In this case, it's all about security.
One of the problems that keeps system architects up at night is maintaining the security of what's going on in memory. Memory operations are the easiest place to disrupt a system's operations because it's only in memory that data is active and changeable. In conventional storage it just sits there. So meeting the security challenges in the market today requires insulating customer data in memory from the outside world.
Oracle has developed a two-tier strategy in its Oracle Cloud Infrastructure of having one computer -- or set of them -- interfacing with the Internet, and another set running customer data. In OCI, the IT perimeter is patrolled by bare metal servers that separate the Internet from operational computers holding and performing operations on customer data. Outsiders can't access customer data to corrupt it.
This ensures that customer data never is exposed on the machine that faces a hostile world. Other aspects of Oracle's autonomous database and its security functions more easily can patrol the control environment as well as the processing environment, while reducing exposure to a variety of risks.

New Form of Enterprise Computing?

Oracle introduced the Gen2 Cloud with these features and the name should be taken seriously; it's not simply marketing hype. Now the real question becomes whether or how fast the industry will adopt this strategy.
On the plus side, OCI is an oasis in a time of drought, but on the minus side it comes from a vendor that makes no bones about wanting to integrate solutions vertically, thus locking out competition. How comfortable do you feel with all your eggs in that basket?
The answers to these issues are several and admittedly idiosyncratic. Oracle loves standards and is involved in more than 200 standards-setting bodies. Standards involve multiple vendors and their products and provide an amount of openness.
At first blush, much of the strategy for Gen2 Cloud looks to come from an assemblage of off-the-shelf parts. Of course, it also involves Oracle's standards-based, but still proprietary, autonomous database. That database runs on proprietary hardware such as Exadata -- a specialized device that keeps databases in memory for optimum performance.
Controller board makers all built to the standards of the greater architecture -- the CPU instruction set, bus, and operating system, for instance. If the analogy holds, there's no reason we can't expect that a new form of enterprise computing can't support a similar approach with OCI or some variant of it.

My Two Bits

For much of IT's history, compute power was expensive and users went to great lengths to optimize its use. However, expense has ceased being an issue with Moore's Law playing out over the last half-century, and the question of adding a layer of computing simply to protect the system, or adding a layer of computing to support in-memory database activities, should not be much of an issue any more.
Significantly, cloud computing can make this approach to security affordable to smaller businesses, and Oracle announced an offering that can place OCI on premises in more well-heeled organizations.
As with any disruptive innovation, which is what OCI really is, there will be a lag phase as organizations come up to speed. My general observation is that as the cost of a new disruption increases, so does the time to full deployment.
However, Oracle's two-pronged approach -- delivering OCI to big firms and placing OCI in the hands of most cloud users as part of a recurring charge -- could accelerate adoption and leave us with a vastly different IT landscape in the next five years.

What The Color Of Your Urine Says About Your Health

Written By Sahani Brothers on Tuesday, October 30, 2018 | 10:53:00 AM


The color of your urine can vary every time you go. Sometimes it will be clear, other times it will be more yellow or even a dark amber color. What most people ignore, or don’t realize, is that every time you pee, you have the chance to learn something about yourself. Your urine is a good indicator for everything from how your vital organs are functioning to basic health indications, like how hydrated your body is.



The Cleveland Clinic in Ohio has published some informative information detailing what the different colors of urine may indicate about a person’s health. For the most part, your change in urine reverts back to how hydrated your body is at that moment. Dr. Daniel Shoskes, a urologist at the Cleveland Clinic, states, “A lot of changes simply come from the state of hydration, which is affected by a whole bunch of things you’re doing,” he also notes, “the various shades of yellow to white to dark can just be a sign of how much fluid you are taking in versus how much you’re putting out.”

However, hydration is not the only thing our urine can indicate. When the color starts to stray from the more traditional hues of yellow is when your urine starts to indicate there may be concern for a bigger health condition. Two conditions to take extra note of are red colored urine and brown colored urine. These colors are indicators that your kidneys and liver, respectively, may be experiencing some problems.

It is important to note that normal urine color ranges from pale yellow to deep amber. The range is a caused by both the concentration of your urine and a pigment called urochrome. Normal urine color varies, depending on how much fluids, particularly water, you drink during the day. Fluids dilute the concentration of your urine. As you drink more fluids your urine becomes clearer.

In addition, pigments and other compounds found in the foods, supplements, medications or other things your body intakes may change the color of your urine.

BELOW ARE THE RANGES OF COLOR YOUR URINE MIGHT BE AND THE CORRESPONDING HEALTH INDICATION(S) FOR EACH COLOR.
Clear/Transparent– You are over-hydrated. This usually is a sign that you are drinking too much water. This is rarely harmful to your body; rather, it’s an indication you can cut back on how much water you are drinking.

Transparent Yellow– You are normal. A transparent yellow is the optimal color you want your urine to be. It indicates that your body is both functioning properly and that your body is hydrated.

Dark Yellow– This is another normal color for your urine. This indicates that your body is functioning properly, but it is an indication your body is slightly dehydrated. This is where you want to start thinking about drinking some more water.

Amber or Honey– Again, this is normal. Your body is still functioning properly, but at this point it has become dehydrated and you should start to intake more fluids to replenish your body. Lighter shades of yellow typically indicate a well-hydrated body.

Orange– This is another sign you may be dehydrated. In some instances food dyes can cause this discoloration as well as some medications. Some laxatives, and certain chemotherapy drugs can lead to orange urine.


However, orange urine could also be a liver or bile duct condition. This condition is typically coupled with light-colored stools and it is important to consult a health care practitioner if the color does not change.

Blue or Green– Blue or green urine, for most people, would certainly cause a double take and give you quite the shock. However, it is important to note that blue or green urine is extremely rare and would not be the first indicator that you are suffering from a serious condition. Dyes are often associated with blue or green urine, such as brightly colored food dyes (although most dyes do not affect people). Hypercalcemia, a rarely inherited disorder, can cause blue urine and some urinary tract infections can cause green urine.

Cloudy or Murky– If this persists it may be the sign of kidney problems or a urinary tract infection and you should consult your healthcare practitioner. However, if this only happens rarely or occasionally, it is not an alarming health condition. The occasional cloudy or murky urine can indicate you have excess protein in your diet or be an indication of the force you are peeing with.



Syrup or Brown Ale– This can be an indication of either severe dehydration or a liver disease. Some foods and medication can change your urine dark brown. A diet rich in fava beans (in large amounts), rhubarb or aloe can cause dark brown urine. Some medications can also be responsible for dark brown urine.

If you have dark brown urine it is important to increase your water intake. If there are not any changes in the color of your urine you should consult your healthcare practitioner. Dark brown urine can be an indication of liver disease.

Red or Pink– This is undoubtedly alarming to see, but it is not always an indication of a serious health condition. There are four things that can cause your urine to be pink or red. Blood, food, medications, or toxins, may cause your urine to be red or pink. A diet heavy in beets, blueberries, blackberries, or rhubarb can cause this discoloration. Toxins, lead or mercury, in high amounts can cause red or pink urine as well. These toxins should be carefully monitored to prevent lead or mercury poisoning.

The last factor that can cause red or pink urine is a condition where blood is in the urine. When urine is discolored from blood it is often an indication of an underlying health condition. Blood in your urine can be from a variety of different health conditions, such as, urinary tract infections, tumors (both cancerous and noncancerous), prostate problems (i.e. an enlarged prostate), kidney stones or disease, and bladder stones.

FACTORS THAT PUT YOU AT RISK OF MEDICAL CONDITIONS THAT CAN CAUSE BLOOD IN YOUR URINE INCLUDE THE FOLLOWING:
Age. Tumors of the bladder and kidney are more common in older people. Men over 50 have a higher probability of an enlarged prostate, which can cause blood in your urine.

Your sex. Men are more likely to contract kidney stones or bladder stones resulting in blood in their urine. Whereas, women are more likely to contact a urinary tract infection (more than 50% of women will contract a urinary tract infection at some point in their life), which can cause blood in their urine.

Family history. A family history of kidney disease or kidney stones makes it more likely that you’ll develop these problems. Both can cause blood in the urine.

Strenuous exercise. Distance runners are most at risk, but anyone who exercises vigorously can have urinary bleeding.

What Can We Expect From AI?



This story was originally published on April 12, 2018, and is brought to you today as part of our Best of ECT News series.
Fear mongering about killer robots and the recent deaths connected with Uber and Tesla autonomous vehicles have rekindled concerns about artificial intelligence in the machines around us. We are well beyond answering Alan Turing's question, "can machines think?" There is now good reason to ask how we should think of AI, and what we should expect from it.
There have been phenomenal advances in AI in just the past few years. They are due in part to advances in processor technology that have increased exponentially the compute performance for artificial neural networks, the development of deep learning software frameworks, and the massive amounts of data mined directly from the Internet and the world around us.
We now can train artificial neural networks in the time it would take to make a cup of coffee. Should that scare people? Not really.

It Won't Be Perfect

You have to remember that these solutions are being trained for a specific function. They do not think out of the box, do not ponder the meaning of life, and do not have feelings. In most cases, especially today, both the initial training and continued training are limited to large server systems in cloud data centers.
As a result, public interaction with AI is limited to cloud-related services like Web browsers or trained models that then are passed down to what we call "edge devices" (referring to the edge of the network) such as smart speakers, smartphones or even cars.
Eventually, continued training or even initial training may be done at the edge, but that may take a revolutionary change in processor technology -- such as neuromorphic computing, which is only in the research stages.
"AI" is exactly as the name implies -- the ability to acquire and apply knowledge and skills -- meaning that it learns over time and, more importantly, learns with additional data. The more data a system utilizes for training in the form of files or even live sensors, the more accurate it will be in performing a specific task.
However, as a form of intelligence, it never will be perfect. Just as humans learn through new information and interactions, so do machines. New teenage drivers may be caught by surprise the first time they drive on ice, but they learn from the experience and get better with time. So too will AI-based systems, but there always will be uncertainty with new data or circumstances.

We'll All Be Safer

The potential for AI to enhance people's lives and change society are endless, but the areas where we'll see the greatest short-term impact are healthcare and transportation. Consider the possibility of having genetically engineered prescriptions for each person, or the ability to find cures for an infectious disease in days, or even hours, because of the abilities of AI systems.
Also think about autonomous trucks and cars being able to ferry people and goods around the world with no need for stop lights. This is all possible, and it's coming sooner than you think.
AI already is used in a wide variety of scientific, financial, Web applications, user interfaces, manufacturing, and more. This is one of the most enabling advances in technology ever -- and like other major advances, it will change the world dramatically. However, it won't be perfect.
With autonomous vehicles, for example, the only way to eliminate any possibility of a human death is to separate pedestrian and vehicular traffic completely. That might happen, but it will require significant infrastructure changes that could take from decades to a century.
As a result, there will be more accidents that may result in more deaths from cars and other autonomous machines enabled by AI. However, the number of deaths and injuries will be drastically lower compared to human-operated machines. Just as airline accidents have become uncommon, so too will auto and other accidents, due to the use of AI. The rarity of such accidents, however, will result in spectacular headlines when they do occur.
AI also will be used in defense applications, another case in which it should improve systems to reduce or prevent virtual and physical attacks, as well as loss of human life.
So, what should we expect from AI? We should expect a safer world with significant advances enabled through intelligent systems. How should we think about AI? We should consider it a breakthrough technology that already is changing the world around us for the better.

This Is Why Your Phone Battery Goes Flat So Soon. Some Helpful Advice

Written By Sahani Brothers on Monday, July 17, 2017 | 4:22:00 AM

This Is Why Your Phone Battery Goes Flat So Soon. 
Some Helpful Advice

Today’s smartphones are more than just means of communication. We also use them to surf in the Internet, watch videos, read news and play games. No wonder, it is so frustrating, when the smartphone battery goes flat. But more often than not, it is the result of battery misuse.

img src: 


Here are some reasons why your phone battery runs down too soon.

1. You charge your smartphone to 100%

It is believed that a phone should be fully charged. According to experts, it is better to maintain the charge level between 30 and 80%, with periodic short recharges.

2. You let your phone discharge completely

This habit kills the battery. It is better to recharge it before the low battery message. The phone should be completely discharged only once in two months to calibrate the battery.


3. You let the battery overheat

Smartphone batteries react very negatively to high temperatures. Their optimal temperature range is between 1 and 35°C.

4. You use wireless charger too often

Wireless chargers can cause battery overheat too.


5. You charge your phone with the case still on

When your smartphone becomes warm while charging, the case won’t let the heat out and cause the battery overheat.

6. You store your spare phone uncharged

Many people have a spare phone in case their first phone goes flat. Remember, that the spare phone will run down soon too, if you don’t keep it half-charged, at least.

7. You use the unsuitable charging cable

Each phone model has its own charging cable. Sometimes, cables of other brands may overcharge or undercharge smartphone batteries.
