How to Protect Yourself From Facebook Hackers Who Contact You As Friends!

I was connected to Facebook the other day, and I received a chat message from an old friend of mine, someone I knew at the university, and to whom I never talked since that time, that is some 19 years ago.After some chat about how each one was doing, he asked me if I could do him a favor: He needed a recharge card for a cell phone for someone in Paris, and he told me that he will transfer money to me via a money transfer service.I was feeling that it was strange to receive a favor request from a friend to whom I haven't talked for ages, but it was maybe logical since his country of residence was not the same as mine. Thus, I asked him when he wanted the card, and he said "right now, today".

Then he added "I don't like to ask anything from anyone, but I really need it, and because you're like a brother to me, I am asking you... "I was never like a brother to that person! Was there a secret virtual bond between him and me without me realizing?Still, since the favor he asked for was not a big deal to me, and since I like to serve friends, I was going to follow. I enquired further, and he told me to get him a 3 months recharge card or 2 cards of 1 month, which is not very familiar to me because I don't know how the recharge cards process works.All that happened through Facebook chat. Right after, and while I was preparing myself to go get the card, I started reasoning:-What was the eventuality of a friend to whom I haven't talked for 19 years contact me suddenly and ask for a favor?-Why would a friend to whom I was never very close tell me I am like a brother to him?And then it came to me that it was not him, that it couldn't be him.

It was someone using his account to request recharge cards from his contacts or other favors.There was no doubt to me anymore that my friend's account was hacked, and that the person who contacted me was a hacker trying to take advantage of the bonds and relationships of my friend. Maybe if I asked him a question about my friend or how I knew him, etc. he could even answer because Facebook contains a lot of personal information.I looked in my friend's Facebook page if any information about his mobile number or email was found (even though email is not even secure because the hacker may have reached his Facebook account from hacking his email, or he may have also hacked his email account) to contact him and tell him that his account was hacked, but I couldn't find any.I then told the hacker that I will contact him to give him the card number, and as expected he told me that his mobile was not with him (under repair): actually I didn't even know the number, I was just bluffing. I told him that I couldn't give him the card if I couldn't call him, he first asked why, then he said that he will contact me.

In my case, and even though the friend that contacted me was someone that I haven't talked to for years, I believed at first that it was him. But the hacker could have done better, and read in the hacked account past chats or in the hacked account contact friends walls how the hacked account holder used to interact which what friends in particular, when, in which way, etc. and thus the possibility is there.This is why I decided to write this post, so that:- If a friend (even a close one) contacts you via email or Facebook or whatever electronic means (chat software, small messages, etc.), you do not communicate personal information to him or her until you make sure in a way or another that it is him or her- If you feel someone is asking you for something strange or unusual, do not hesitate to be suspicious, because it is the right attitude.- Most importantly, use different complicated passwords for all your electronic email and social accounts with a lot of special characters and a combination of numbers and letters both upper and lower case.To get more information click here free facebook hack

Some Properties Related to the Valve

It is pleasant to see that the development of the valve industry has been bringing in benefits to all aspects. And it is appreciated to choose a proper one to make good use of it. Generally speaking, there are some properties that should be kept in mind while selecting the required valve. So, what are the major properties when people manufacture or select the valve?Firstly, the seal performance should be taken into account which refers to the ability to prevent the leakage. It is important. Otherwise, the leakage would lead the machine to fail to work, even lead to some industrial accidents. Especially, there are three points that need much more attention. They are the attachment between the opening and closing device and the two seal surfaces of the valve seat, the space between the valve stem and stuffing and the joint between the valve body and the valve cover. The previous one would influence the ability of cutting off the medium and the latter two ones would cause the industrial pollution or some worse consequences. No matter what, the seal performance rises to be important when evaluating and selecting the valve.And as we all know that the valve is used to control the medium, the effects caused by the medium need our attention. When the medium comes across the valve, the resistance would occur. Then, the medium would consume the energy more or less to overcome the resistance. As a result, a better valve should take this factor into consideration to reduce the resistance as much as possible.Then, the force which is also needed to open or close the valve should be driven attention to. The force is expected to endure the pressure caused by the sealing surfaces and the resistance caused valve stem and the stuffing and other attachments. And it should be mentioned that the force is changeable when opening and closing the device. To reduce the moment would be a good choice. And the speed to open and close the valve should be designed according to the specific specifications.Besides, there are some other properties which are significant to the performance of the valve. The sensitivity and reliability refer to the abilities related to the reflection of the changeable medium. They are especially important to the throttle valve, reducing valve, control valve and security valve.In words, there are many aspects related to the designing, manufacturing and selecting of the various valve. Moreover, the service life is also important from the economic consideration. Above all, do choose a good and proper valve would do great favors.To get more information click here Valve repair in USA or you can also click here Valve Modification company in Texas

How to Launch a 65Gbps DDoS, and How to Stop One

Yesterday I posted a post mortem on an outage we had Saturday. The outage was caused when we applied an overly aggressive rate limit to traffic on our network while battling a determined DDoS attacker. In the process of writing it I mentioned that we'd seen a 65Gbps DDoS earlier on Saturday. I've received several questions since that all go something like: "65Gbps DDoS!? Who launches such an attack and how do you defend yourself against it?!" So I thought I'd give a bit more detail.
What Constitutes a Big DDoS?
A 65Gbps DDoS is a big attack, easily in the top 5% of the biggest attacks we see. The graph below shows the volume of the attack hitting our EU data centers (the green line represents inbound traffic). When an attack is 65Gbps that means every second 65 Gigabits of data is sent to our network. That's the equivalent data volume of watching 3,400 HD TV channels all at the same time. It's a ton of data. Most network connections are measured in 100Mbps, 1Gbps or 10Gbps so attacks like this would quickly saturate even a large Internet connection.
At CloudFlare, an attack needs to get over about 5Gbps to set off alarms with our ops team. Even then, our automated network defenses usually stop attacks without the need of any manual intervention. When an attack gets up in the tens of Gigabits of data per second, our ops team starts monitoring the attack: applying filters and shifting traffic to ensure the attacked customer's site stays online and none of the rest of our network is affected.
So You Want to Launch a DDoS
So how does an attacker generate 65Gbps of traffic? It is highly unlikely that the attacker has a single machine with a big enough Internet connection to generate that much traffic on its own. One way to generate that much traffic is through a botnet. A botnet is a collection of PCs that have been compromised with a virus and can be controlled by what is known as a botnet herder.
Botnet herders will often rent out access to their botnets, often billing in 15 minute increments (just like lawyers). Rental prices depend on the size of the botnets. Traditionally, email spammers purchased time on botnets in order to send their messages to appear to come from a large number of sources. As email spam has become less profitable with the rise of better spam filters, botnet herders have increasingly turned to renting out their networks of compromised machines to attackers wanting to launch a DDoS attack.
To launch a 65Gbps attack, you'd need a botnet with at least 65,000 compromised machines each capable of sending 1Mbps of upstream data. Given that many of these compromised computers are in the developing world where connections are slower, and many of the machines that make up part of a botnet may not be online at any given time, the actual size of the botnet necessary to launch that attack would likely need to be at least 10x that size. While by no means unheard of, that's a large botnet and using all its resources to launch a DDoS risks ISPs detecting many of the compromised machines and taking them offline.
Amplifying the Attacks
Since renting a large botnet can be expensive and unwieldy, attackers typically look for additional ways to amplify the size of their attacks. The attack on Saturday used one such amplification technique called DNS reflection. To understand how these work, you need to understand a bit about how DNS works.
When you first sign up for an Internet connection, your ISP will provide you with a recursive DNS server, also known as a DNS resolver. When you click on a link, your computer sends a lookup to your ISP's DNS resolver. The lookup is asking a question, like: what is the IP address of the server for cloudflare.com? If the DNS resolver you query knows the answer, because someone has already asked it recently and the answer is cached, it responds. If it doesn't, it passes the request on to the authoritative DNS for the domain.
Typically, an ISP's DNS resolvers are setup to only answer requests from the ISP's clients. Unfortunately, there are a large number of misconfigured DNS resolvers that will accept queries from anyone on the Internet. These are known as "open resolvers" and they are a sort of latent landmine on the Internet just waiting to explode when misused.
DNS queries are usually sent via the UDP protocol. UDP is a fire-and-forget protocol, meaning that there is no handshake to establish that where a packet says it is coming from actually is where it is coming from. This means, if you're an attacker, you can forge the header of a UDP packet to say it is coming from a particular IP you want to attack and send that forged packet to an open DNS resolver. The DNS resolver will reply back with a response to the forged IP address with an answer to whatever question was asked.

Why Online Dating Is The Opium Of The Masses

With two out of every five singletons in Europe and the USA now turning to the internet to find a partner, it would be safe to say that the phenomenon of online dating has changed the social and dating habits of tens of millions of people from Newcastle to New York. But why has an activity that could only be classed as an amusing diversion five years ago become such an addictive and central part of so many people's everyday lives? The answer to this question can be encapsulated in the ten short paragraphs:-

1. No more smokey bars and clubs. In the bad old days, single people on the prowl would trawl the local hostelries in their towns and cities looking for that special connection with someone who takes their fancy. Well, now you can prowl the internet from the comfort of your armchair or office and if you happen to be having a bad hair day, who cares?

2. You don't have to be a teccy. Most online dating sites are simple to navigate and deliberately don't incorporate features which are difficult to understand. Even your average internet virgin can master the art of using a dating site.

3. There's a site that's just right for you. There are global sites, country specific sites, city specific sites and niche sites for seniors, bikers, single parents, gay guys and girls and just about everything else you can think of. If you can't find an online service that exactly suits your location and lifestyle, you're not looking hard enough.

4. A choice of thousands. Most successful sites have thousands of active members on their databases. When you walk into a party or a club, how many single people will you see who might be right for you? Probably only a handful. Well now you can switch on your computer and be completely spoilt for choice.

5. Find just your type. A good dating site will present you with a series of options when you start browsing through the profiles of other members. As well as finding people who you'll find physically attractive, you'll also be able to refine your search to people who you'll also find compatible in terms of personality and lifestyle choices.

6. Instant gratification. Now you don't have to stand in the corner nursing your beer or glass of wine vainly hoping that the good-looking guy or girl across the room will come over and talk to you. When you spot someone you like on an online dating site - you can just send them a message and introduce yourself. And when you do so, your real email address is never revealed so you don't have to worry about giving out personal contact details to complete strangers.

7. You control the pace. You can message people as and when you want to and respond to other people's mails at your leisure. It's completely up to you how frequently you use your chosen site and who you want to make contact with. Take it fast or take it slow - it's your choice to make.

8. There's always someone else. If any member you contact doesn't respond or you decide that someone you've been exchanging mails with isn't quite suitable, you can just move on to someone else. Good dating sites attract hundreds and in many cases, thousands of new members every day so why put all your eggs in one basket when you have many more baskets at your finger-tips?

9. Widen your social network. Yes, the majority of people join dating sites to put some fizz and sparkle into their love lives; but many people do so to make new friends as well. Maybe you've just arrived in a town or city to take up a new job and what better and quicker way is there to start making new friends than to join an online community of like-minded singles in your own age group?

10. It's great fun. Let's face it, we could all do with injecting a little more of the fun factor into our lives from time to time and surfing the net for attractive compatible dates is a great way to do just that. And it doesn't cost any more than a round of drinks so it isn't really much of a risk in financial terms. There's very little to lose and everything to gain.

So there you have it; the delights of online dating are available to anyone who has access to a computer screen and if you're single yourself and you've yet to take the plunge, why are you waiting? It's what the internet is for!

Medicine Vaporizers And How Do They Work?

Depending on your specific need for your health you may or may not have needed to use a vaporizer. In the medical device field a vaporizer is typically referred to as a nebulizer. A nebulizer is a medical device that is used to take prescription respiratory medication and to transform that into vapor form. The way that this occurs is quite complex but can be explained here in simple terms. Essentially, when the medicine is placed inside the product and the activation button is turned on the product begins to work. The nebulizer shoots high compressed air through the liquid prescription medicine and then subsequently that liquid is transformed into a vapor form that can be easily breathed in through the body.

The reason why you would need to do this is because when the medicine is in actual vapor form then it can be taken in by the body in a much easier fashion.In addition, by using a vaporizer or in other words a nebulizer the medicine begins to go to work at a much faster rate that it would have if it was taken via the normal method of ingestion. Some of the most common types of prescriptions that are used with a vaporizer is Albuterol which in essence is the leading asthma medication in the market. The most impressive aspect of the device is the fact that it provides the complete functionality of providing medication in vapor form while doing all of this on the go. The product is completely portable which means that you can take it with you wherever you go with the comfort that you know you will have access to it whenever you need. The compressed air is only but one variety of the devices and there are other ways of transforming the medication in order to be administered to the body.To get more information click here Smoke Shops or you can also click here Vaporizers

Choosing A Quality Accident Lawyer

Hiring an accident lawyer should be a thorough process. If individuals have been injured quite seriously, they should rely on family members to help them begin the process of finding good legal representation. If they have been less severely hurt, they can embark on the search themselves. Ultimately, they should choose someone who is qualified to handle a wide range of legal situations.Men and women who have just recently come out of an unexpected accident will in many cases be shaken up.

Lawyers can help to take care of this, and are especially good at securing the appropriate financial compensation, especially for medical bills. Legal representatives are equipped with a range of knowledge and skills and can usually assist victims in getting what they need from the court system.People who are unfamiliar with the actual process of finding a good lawyer would do well to rely on respected members of the community for advice. In fact, if a close family member or friend has been through the same process, he/she might be able to personally recommend someone. The solid, firsthand advice of trusted loved ones should always be explored. It may very well lead them to a good hire.Whenever a legal representative is found, he/she will most likely want to sit down with the client for a formal discussion of the general situation.

Lawyers in these cases will offer some standard advice about what can be expected going forward. The client can also use this meeting as an opportunity to ask pertinent questions that directly relate to his/her own case.If the person is unfamiliar with how the court system works, lawyers can also help out in this regard. Court cases themselves can take weeks and even months to be heard, and clients should be prepared to wait quite a bit to have their particular issues solved. Lawyers can usually help to form a general estimation of when things will be ultimately taken care of.Most good lawyers will employ a team of qualified staff members to assist them with the larger cases. This is important, as it ensures that all bases are covered and that a client is getting all the help he/she deserves.

A dedicated support team means that the client will have a better chance of gaining any needed financial compensation.Family members and friends of the accident victim should come together and offer moral support whenever and wherever it is needed. Medical ailments and legal matters can combine to create quite a bit of stress, and knowing that loved ones are there to help out can be a significant psychological victory.Ultimately, those men and women who are looking around their local areas for an accident lawyer should be sure to do enough research prior to making a decision. When they've scoped out the situation and chosen someone who is eminently qualified, they should get the outcome that they want. That lawyer should have the knowledge, skill, and experience that is needed for the accident victim to win the day.To get more information click here accident lawyer or you can also click here car accident lawyer
