Real Information is always strong and powerful. Everyone wants to real not reality, you can not convince anyone of anything. You can only give them the Real Information, so that they convince themselves
Mobile security is the protection of smart phones, tablets, laptops and other portable computing devices and the networks they connect to from threats and vulnerabilities associated with wireless computing Mobiles security is also known as wireless security.
The block chain is a database of information. This information is not stored in a single place, but across a variety of data servers that participate in the network, this is what is meant by “decentralized” there is no central point. Identities are kept completely private, through the cryptography, however all transactions that happen on the block chain are open to viewing by anyone at any tie for always.
Trust in the block chain is enough to transact with anyone. Every record that’s written on a block chain is secured by a unique cryptographic key, making the block chain and it’s information immutable.
How Does a Block chain Work
A user requests for a transaction
A block representing the transaction is created
The block is broadcast-ed to all the nodes of the network
All the nodes validate the block and the transaction
The block chain is added to the chain
The transaction gets verified and executed
How to create a blockchain transaction?
When 2 parties initiate a transaction, blockchain assigns an encryption
Blockchain verifies the transaction and creates a block
The new block is appended to the blockchain
The blockchain transaction is now complete and the ledger is updated
Database: Block chain is a unique shared database technology. A block chain project must use a structured data repository
Mistrust: Block chain implies multiple non-trusting writers. They don’t allow other users to modify their entries.
Interaction: The block chain transactions often depend on another writer’s transactions created collaboratively without exposing the parties to risks
Writers: Block chain relies on multiple writers who generate transactions modifying the database
Disinter Mediation: No central gatekeeper needed to verify transactions and authenticate their sources
Rules: The database is modified by various non-trusting writers. It must contain integrated rules that restrain the transactions and define legitimate transactions.
7 Ways the blockchain can help the environment
Environmental treaties: Track real impact and compliance of environmental treaties decrease fraud and manipulation
Non-Profits: Track where donations are going decrease inefficiency and bureaucracy in charities
Carbon Tax: Calculate tax for products based on carbon footprint create a reputation system for companies based on emissions
Changing Incentives: Align incentives with sustainable practices create incentives for people to act in sustainable ways
Supply Chains: Transparently track products from origin to store shelf reduce carbon footprint and unsustainable practices.
Recycling: Encourage recycling by providing tokenized reward track and evaluate efficacy of recycling programs
Energy: Increase efficiency with P2P electrical grids improve access to power in areas with poverty or natural disasters.

An attack or a hack through which the attacker users social skills via human interaction to obtain or compromise information about an organization or its computer systems is known as a social engineering attacks. Your data is at risk everyday through social engineering attacks because hacking a human is much easier than hacking a business.
What motivates social engineers?
Obtaining personal information.
Gaining unauthorized access.
Circumventing established procedures.
Because they can.
Personal Approach :- In personal approaches, the social engineering may directly ask for approach in general meeting or gathering and get personal or critical information directly or indirectly about you.
Telephone :- Request information usually through the imitation of a legitimate bank/company through system to get critical information such as bank/credit card data.
Online :- Internet connectivity enables attackers to approach individuals or employee an anonymous internet source and convince them to provide information through a believable user.

Ransomware is an attack that installs covertly on a company’s computer, blocking or limiting user access and demanding a ransom payment to restore it. This is one of the fastest growing cyber threats and is expected to increase 400% every years.
The state of ransomware
25% of organizations had to cease business operations immediately because of ransomware.
81% of business have experienced a cyber attack.
66% have suffered a data breach
35% were victims of ransomware
72% of companies affected by ransomware that could not access data for at least 2 days following the attack.
32% that lost access to their data for
$10-$50 million estimated monthly income for cyber criminals from ransomware
Ways to Stop Social Engineering Attack
Walk through company and make sure employees are not leaving personal or sensitive information in plain view of passing people such as e-mail accounts, login information, passwords etc.
Use dummy accounts to monitor networks, and also use the admin account as a dummy as well and monitor who attempts to access it and trap them in the act.
Make a security policy that enforces that passwords must contain a certain combination of words,numbers and characters.
Never allow an employee to leave their terminal or desk without first logging out of their respected machine or workstation
Tips for Avoiding a Social Engineering Attack
Limit public information:- Limit the amount of personal information that you share online.
Be a skeptical:- Always question requests for sensitive information.
Trust but verify:- Don’t share information with people you don’t know unless you can verify their identity.
Call them back:- Through the main switchboard if possible.
No password over the phone:- Never share your password with anyone over the phone
Spot Fake E-mails and Stay Safe
In June 2015, famous company Ubiquiti networks Inc. willing wired $46.7 million to fake bank accounts in china. Why? Because the company CEO asked them to an email. Of course, the actual CEO never made any such request a group of hackers did.

Spelling and grammar errors:- The email contains clear spelling or grammatical errors or emails from legitimate companies are normally proof read extensively before sending.
Requests personal information:- The email requests that you follow a link to log in, or request personal information such as a credit card pin number or password.
High urgency or threats:- The email creates a high sense of urgency, or threatens consequences for inaction.
Fake web links:- The sender’s displayed name and email address do not match the purported company the email represents, or the links send the recipient to other websites not associated with the purported company
Notes : 80% of attacks are phishing
Social engineering exploits the goodwill of unwitting victims. Here’s how….
Website Spoofing:- Bogus websites masquerade as the real thing, tricking victims into sharing sensitive information.

Poser :- Attackers poses as a vendor, client or employee and sends email from what links like a reputable source.
How to Spot a Phishing
Phishing is a technique used to fraudulently obtain usernames, passwords, credit card numbers and other sensitive information.
Fraudulent emails typically ask you to:
Open an attachment
Click on link, redirecting you to a malicious website.
You may be prompted to enter personal information.
Types of Phishing Attacks
Spear Phishing: A highly targeted form of phishing that hones in on a specific group of individuals or organization.
Whaling: A form of phishing, targeted at executive level individuals.
Cloning: Whereby a legitimate email is duplicated but, the content is replaced with malicious links or attachments.
Social networks are websites or apps that allow people to connect with friends and even make new fiends, virtually, and share content, interact, create communities of similar interests such as Working, games reading friendship relationships etc.
A social network has always existed, but the way in which it connects has changed dramatically .Some most popular social networks or social media apps are Facebook, Twitter, Yahoo, Blogger and LinkedIn.

According to some studies made by “the telegraph”, exposure to wireless waves interfere with the human body and can create problems such as: Short term memory loss, Lethargy, Cardiac problems, Sleep disturbance.
Wireless Internet routers or WiFi modems use dangerous electromagnetic radiation to send their signals to your computer through walls. If you have a wireless internet router set up in your home or office you are receiving massive EMF exposure, and living or working in a dangerous soup of radiation.
Not only atmospheric + ve charges, the wireless WiFi devices + cell phone radiation and the static electricity but also other pollutants.
Reduce your WiFi Radiation
We know that some people can’t quite bring themselves to surrender their wireless devices so here are some tips on reducing Wifi radiation.
Keep your distance : WiFi radiation drops off significantly with distance. many routers have a strong enough signal to maintain a connection up to 100m from the router.
Switch off at Night : Studies tell us that the biggest danger with WiFi radiation comes from nighttime exposures; cellular regeneration, rejuvenation, and detoxification is impeded and notably melatonin production can be significantly reduced.
Use USB Adaptors wisely: If you are use a USB WiFi adapter use it on a USB extension cable. The same goes if you use a 3G USB dongle to connect to the internet wile you are traveling, an extension cable will significantly reduce your exposure.
The dangers of WiFi are real. Use the above tips to eliminate or reduce your exposure to WiFi radiation.

Yes –> 61%
No –> 24%
Don’t know –> 15%
Risk to Pregnant Women
There are radiation related risks throughout pregnancy which are related to the stage of pregnancy and absorbed dose and also radiation risks are most significant during organogenesis and in the early fetal period somewhat less in the 2nd trimester and least in the third trimester.
A pregnant woman and the fetus both are vulnerable a RF radiations pass placental barrier and continuously react with the developing embryo and increasing cells. Use of WiFi during pregnancy can lead to greater likelihood for behavioral problems in their children. It is believed that the eggs, which form the embryo can be affected and the damage will become apparent after the child reaches puberty.

Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the both two! You might not believe, but there are human clones among us right now. They’re identical twins, created naturally not made in lab.
There are many types of cloning, some are given below:
Man is not God and shall not play God. Imagine yourself a clone and the only reason you have entered this world is to provide spare organs. What is the purpose of you life?
Purpose of cloning:
The production of babies for those such as infertile couples, single women, gays and couples whose children have died.
With cloning, doctors who perform plastic surgeries instead of using silicon and others materials which are foreign to the body, will be able to manufacture bone, fat and connective tissue that matches the patient’s tissue exactly
The goal of cloning is to take control of the reproductive process.
You are able to select the specific combination of genes to get what you want.
That’s appealing to people who breed animals
Plants are easy to clone- gardeners often take cutting to grow new plants which are clones
Cloning is an example of asexual reproduction where genetic information comes from just one parent
Potato plants reproduce vegetatively by growing tubers, from which the new plant will grow these are clones
Now we discuss more interesting topics:
SIM or Subscriber identification Module is
a smart card that is include in every cellphone of the GSM family of networks
How to Clone SIM Card?
Scan the SIM to extract IMSI and KI, the 128 bit key.
Now put the IMSI and Ki into some card software.
And then copy it into a new SIM card
We now have a cloned SIM
How is a Phone Cloned?
Capture the ESN/MIN pair or SIM/IMEI pair.
Clone the ESN/MIN pair using electronic scanning devices.
The cloner reprograms or alters the microchip of any wireless phone.
The ESN/MINs are transferred using a computer to a device.
These devices are connected to handsets.
New information is legitimate phone into the phone.
Thus a clone of the legitimate phone is thus obtained.
What is the purpose of cloning?
Making fraudulent phone calls
Getting owner messages.
Using internet on owners bill
Using phone to commit a crime.
Getting personal information of owner.
Listening owner calls.
To tease anybody etc.
Cloning Laws Around the World
No federal law banning cloning , but several states have passed their own laws to ban the practice. The U.S. Food and Drug Administration has also said that anyone in the United States attempting human cloning must first get its permission.
In Japan Human cloning is a crime that is punishable by up 10 years in prison
UK has allowed cloning human embryos, but is working to pass legislation to stop total human cloning.
Cloning, Good or Bad
People can get an animal that looks the same as the pet they had
Scientists can clone organs and help people live longer
Scientists can also clone body parts such as ears to surgically attach to a person
Cloned animals are safe to eat
The offspring of cloned animals are often born deformed
It is against religious beliefs
Pets that are cloned often do not come out having the same personality and can look different
Why Cloning is Bad for Society
It will contradict the religious beliefs
It may build a new world of fraud and unethical practices
