Many people spend literally thousands of dollars a month on using proxies, a fact that surprises many. After all if you do a quick google search you’ll find lots of lists of free proxies all over the place. Many are listed as being super secure and elite, so why on earth do people spend lots of money on them.
Well firstly, it’s important to remember that anyone who has the vaguest clue about online privacy, anonymity and the risks of cyber crime would never go anywhere near a free proxy server. At best there badly configured proxies accidentally left open by some overworked networked admin somewhere, which means that you’re potentially stealing bandwidth if you use them. At worst, and it’s an increasingly likely scenario the proxy has been left open on purpose in order to steal user credentials like emails, accounts and passwords. It’s not much of a choice really, so you’d be advised to stay well clear of them.
So there is a big market for safe and legitimate proxies for a variety of uses and one of the most popular is buying sneakers from online web retailers. You see all the big retailers of sneakers (trainers in parts of Europe) release limited edition versions of their sneakers which are very much in demand. You can try and buy them online but it’s very difficult to do and you’d have to be very quick and luck to even grab as single pair.
Obviously because they’re scarce and valuable then some people want to get lots of these – there’s an obvious profit opportunity there even if you don’t want to wear them. So how do people get to buy loads of these sneakers online from palces like Supreme, Footlocker and Nike well they basically use software.
There are lots of automated tools and bots which you can configure to attempt to buy these sneakers when they become available. If you get the right set up you can buy loads of these for whatever purpose you like. The software acts like a human purchaser but with infinite patience repeatedly trying to buy the specified sneakers until they are successful. Lots of people buy up loads of these and indeed run successful businesses simply reselling these shoes at inflated prices.
TO maximise their chances they install the software programs on high availability servers with lots of bandwidth. These can be programmed remotely to leap into action as soon as a new release becomes available.
The issue is that obviously the retailers don’t like this and try and block access to all automated efforts to buy the sneakers. They look for things like multiple connections from the same IP addresses and ban these instantly. Which means even if you have your own server if it tries to often to buy the sneakers then it will get banned and the server and software will be unusable.
The solution is to add another layer of protection by utilizing sneaker proxies to hide your location and allow the software or Bot to rotate it’s identity in order to keep running. It’s not difficult to do but the the essential requirement is that these are sneaker proxies with a special configuration.
The first important component which you’ll never get with free proxies is to ensure it has lots of residential IP addresses. These are actually quite hard to get because these addresses are only normally handed out by ISPs to home users. Most online retailers know that people try to hide their locations and often block all non-residential IP addresses automatically. Normal commercial VPN and proxies will have commercial IP addresses so won’t work in this situation.
This is what makes sneaker proxies so special, they should definitely have residential IP addresses which makes them pretty much undetectable from normal home users. Unfortunately it’s also what makes them so expensive as obtaining, supporting and running these sorts of residential proxies is pretty costly.
There are a few companies around who have managed to obtain and specialize in residential IP proxies but there aren’t many. In our opinion the best and most trusted supplier is a company called Storm Proxies which you can find in the link below.
One of the earliest uses of proxy servers were to add some control over access and bandwidth to the internet from large corporate networks. Instead of having thousands of individual computers accessing the same resources individually, a proxy can request, cache and forward the same information. Firstly this helps reduce network traffic but more importantly allows network administrators to control and check both incoming and outgoing traffic in a single spot.
This is of course, not their only use and nowadays you can find proxies all over the place in all sorts of configurations. The proxy server has found a new lease of life as an effective way of hiding your location and staying anonymous online. In this article we are going to talk about a specialised configuration now commonly used for supporting automated tools and bots that people use online.
It’s easy to hide behind a single proxy to complete a single task, however if you want to use software which performs multiple tasks then it becomes a little more complicated. The main issue is that if a proxy is detected it can be blocked or filtered really easily, adding it’s IP addresses to a black list effectively make that proxy useless with regards that site.
You may have come across this message in some form when using Google for instance –
it’s simply a message triggered when Google receives too many requests from a single IP address. You can actually cause it to happen manually just by searching too quickly but obviously any software will trigger it much more easily. So for example, research tools which send multiple requests to search engines becoming completely useless in this situation.
This is a problem suffered by all sorts of tools which need to process multiple connections to specific websites. Things like SEO tools, automated posters, Sneaker and Twitter bots and hundreds of other automated tools that people use online to make money online. None of them will work properly without using a significant number of proxies to support these requests.
Using Residential Proxies with Rotating IPs for Automated Tools
There are several important things to remember about using proxies in this way, including the type of IP addresses that are assigned to them. There are two major classifications of available IP addresses, commercial and residential.
Commercial IP Addresses – are assigned to private companies and datacentres.
Residential IP Addresses – are assigned to individuals and home users usually through their ISP (Internet Service Providers)
By far the most valuable are residential IP addresses simply because commercial addresses are mostly detected and blocked automatically. Most commercial sites want to allow ordinary users, who will almost always originate from a residential IP address. Unfortunately most commonly available addresses are commercial as they usually are assigned to servers in datacentres.
If you sign up for a web site, hire a dedicated server or even just subscribe to a VPN service – all the IP addresses will be classified as commercial ones. These addresses are actually very simple to get, however the home user addresses needed for dedicated residential proxies are much, much harder to obtain. If you try and search you’ll find there are not many residential IP providers online. The primary source of these addresses is ISPs however these are only allocated to individuals at specific locations. It’s impossible to simply buy a range of residential IP addresses and assign them to some high powered servers stored in a datacentre unfortunately. They can be obtained but the process requires contacts, expertise and lots of hardware to support them.
Private residential proxies and their addresses are therefore extremely valuable and it’s vital that they do not become banned or blocked from overuse. Although the classification of these addresses won’t cause them to be blocked, they will be banned if too many concurrent connections originate from them.
A simple proxy server with a few residential IP addresses, isn’t going to cut it – a few automated tools running on a high bandwidth connection is going to burn through them pretty quickly. People running all sorts of tools like Twitter Bots, Sneaker Bots and high end SEO tools need thousands of these addresses in order operate. Even if you buy rotating proxies there’s no guarantee that this will be sufficient to support many of these tools.
Fortunately a couple of companies, and it’s no more than this have built something much more sophisticated. These networks consist of residential IPs backconnect rotating proxies which can support thousands of IP addresses and allow all these tools and bots to run without issues. These backconnect proxy servers aren’t single servers which simply forward and receive data like traditional proxies. They are actually a gateway to a mesh of different machines supporting thousands of IP addresses and configurations networked together. Every request is filtered through a different proxy and rotated through a a unique configuration with varying referrer data.
These networks allow you to point at the network and switch through thousands of IP addresses, they even switch the referrer data. They’re obviously extremely difficult to assemble and take ongoing development however they allow thousands of users to run these high powered automated applications. The only company who own and run their own hardware to support these residential backconnect proxies is called Storm Proxies.
You can buy residential proxies and other specialised servers on the link below. they include a 48 money back trial as standard.
HTTP Authentication Since the reverse proxy server masquerades as a Web server, the authentication required by the reverse proxy is Web server authentication. That is, the challenge status code is 401, not 407. See elsewhere in this blog for HTTP authentication, and differences between Web server and proxy server authentication.
Dynamic Content and Reverse Proxying
Dynamic content poses a problem With reverse proxies. If the content is dynamically generated, it cannot be cached efﬁciently. Rather, each request must be forwarded to the origin server. This defeats the benefits of caching in the proxy server, and may in fact impede performance. A common misconception relates to the way CGI scripts are handled. CGI scripts are always executed by the origin server; they are never trans- ferred in their source code/program language form to the proxy server and executed there. Only the result of the CGI execution is passed to the proxy server, and, if marked cacheable, it may be cached by the proxy. As long as the number of dynamic pages is fairly small compared to the total number of requests, reverse proxying can be beneﬁcial as in this case – http://bbciplayerabroad.co.uk/how-to-watch-bbc-iplayer-in-the-usa/. If there are many dynamic pages, they may be duplicated on multiple origin servers, and DNS round robin used to distribute the load among them. The static content may still be handled by reverse proxy servers.
Alternatives to Using Reverse Proxies:
There are a couple of alternatives to reverse proxies. One is the 3 05 Use Proxy status code in HTTP/ 1.1 that is intended for redirecting the client [or an intermediate (forward) proxy] that directly connects to the origin server to go through a proxy server. This releases the proxy in question from having to be a reverse proxy, since the client is now aware of the proxy’s existence in between. The 305 status code is intended as a mechanism for associating a one-site—only proxy server that will not be used for anything else. Note that if a (forward) proxy server is already used by the client, the client will not receive the 305 response. Instead, it is intercepted and handled by the last (forward) proxy in the proxy chain (that’s the proxy that attempted a direct connection to the origin server to begin with).
At the time of this writing, the support for the 305 status code is not widespread, either by client software or proxy servers. Once HTTP/1 becomes more widespread, the use of 305 proxy redirection may be viable option to reverse proxying. Another alternative to reverse proxying is to handle replication ~ ‘ server content by other means.
This can be accomplished by a plugin, the Web server, or by copying content between servers by other too such as FTP or secure rdist. At this time, copying content between servers using out-of-band mechanisms is the most common way of ting up large server pools. As reverse proxy server technology advance» may become an easier mechanism for setting up server pools. SUMMARY Reverse proxying provides an alternative to moving the server from ‘ internal network to the ﬁrewall. As the performance of proxy server \ ” ware increases, they may become a viable solution for synchronizing among multiple replicated servers in a large origin server pool.
One of the problems with using VPN services is that they are difficult to use with devices other than computers. It’s fairly simple to set up a VPN on a computer, laptop or even on tablets.
However nowadays people use things like Smart TVs and media streamers such as the Roku which are difficult to configure to use VPNs even those simpler ones. This configuration issue lies at the heart of the puzzle – which is the best Smart DNS Vs VPN.
Probably the most common uses for a flash router is to act like a VPN service gateway. As you can see from a fast glance from the many sites which deal with Flash Routers, most encourage using one of the many VPN services and are frequently adding new ones. Subscribing to the VPN service is an extremely beneficial way to get access to unblocked content, so if you’re attempting to see US Netflix in Mexico or see BBC Sport on your Roku, employing a subscription service like Identity Cloaker, IPVanish or similar with your router will definitely a fantastic option.
Nevertheless, a VPN service isn’t the only way to unblock popular streaming video & music content. While utilizing a VPN support with your router can permit you to unblock content on devices such as Roku and Apple Television that may Usually not be flashed for VPN usage, you will find other services that could be utilized. The most outstanding is the, easy Smart DNS. Should I Be Using A VPN service or a Smart DNS Router Setup? Smart DNS is a protocol which may be utilized to re route traffic required for determining your geographical location.
Nevertheless, unlike a VPN, Smart DNS doesn’t provide encryption or conceal your IP address. The VPN service creates a tube which change or mask your IP to do it look you’re accessing the website from another location. Smart DNS works like more of a trick, by changing your DNS so sites think you’re qualified to access their content. The reason why SmartD NS differs enormously from a VPN with a better user rate is that it doesn’t require traveling through a remote server location. So a Smart DNS router configuration gives you a number Of the benefits a VPN service may provide without the possible disadvantage of slower speeds from heavy VPNs encryption.
Using SmartDNS is really hard to beat for ease and setup, particularly when utilizing a router upgraded with increased DD WRT firmware. When this Smart DNS router setup is complete, all system that runs throughout The FlashRouter will be using SmartDNS. So with one setup, all devices device on your network like Roku 3, AppleTV, iPads, iPhones may All access SmartDNS enabled content with no person setup. One installment and you’re ready to go!.
So what is a proxy, well the definition actually changes slightly depending on who you are talking to. The origin of the term goes back to the beginning of the web in around 1990 when proxy servers were actually referred to as ‘gateways’. These were simply devices which forwarded packets between different networks, sometimes even converting the different protocols that were being used.
However a simple up to date definition could be as follows:
A proxy server is a computer or system that acts as an intermediary between a client and a server.
They have all sorts of uses within corporate networks but in reality their real popularity has come outside that from ordinary computer users. You see the proxy sits between the computer you are using and the server you are contacting. It relays all information between the two sides and effectively protects the anonymity of the client computer.
This is the main benefit of using a proxy in this context, the proxy hides your location, your computer and identity from the web server you are using.
So Why all Secret Squirrel? UK Proxy Buy or Not?
Most proxy users aren’t looking for total anonymity (although some are), but people have been using proxies for years in order to bypass the various blocks and filters that exist online. For example one of the most popular uses of a proxy server was in order to access British TV Online and blocked media sites such as the BBC iPlayer or Hulu.
The BBC’s wonderful website and application is only accessible if you’re physically located in the United Kingdom – everyone else get’s blocked. However if you connect through a UK proxy first, then the BBC website only sees the location of the proxy and allows access.
It is how millions of people across the world could watch the BBC News or Match of the Day from outside the United Kingdom. As long as their proxy server was located in the UK, their actual location didn’t matter. Exactly the same situation from US sites like Hulu, to access from outside the USA you needed to channel your connection through a proxy server based in the United States.
So does a UK Proxy Unlock Every UK TV site?
Unfortunately no, in fact the reality is that nowadays a proxy is pretty much useless as far as bypassing geographical blocks. The reason is that the inbound connection from a proxy server is actually fairly easy to detect which is what most large scale media sites do. If they detect a connection from a proxy server then access is blocked automatically.
Here’s a example of the message you get when trying to access Netflix through a proxy, it simply won’t let you use the site.
The reality is that there’s little point in buying a UK proxy or indeed one based anywhere in the world. They can still obscure your identity a little, and they stop every website you visit being logged at your ISP but for watching UK TV you need something else.
That something else is a UK VPN service, which in many ways operates in a very similar way. A VPN is a virtual private network connection between your computer and a VPN server. Exactly like a proxy this server acts as an intermediary between you and the web resource you’re trying to access – relaying information both ways. Yet there are important differences, firstly the entire connection is encrypted which means that no-one can access or intercept your data at any point. The second is that a VPN connection is virtually impossible to detect, so none of the media sites are able to block or disconnect the connection.
Here we can see one such VPN service in action, it’s called Identity Cloaker.
As you can see it’s quite straight forward especially on a computer or laptop. You merely click on the country you require and it establishes a connection to that specific VPN server. From that point any website you connect to will only the address of the VPN server not yours, which means that you can access whatever you like irrespective of your location.
Literally millions of people use these VPN services now to bypass blocks and filters of all descriptions. Some use them to bypass state controlled filters such as in China and Turkey where the internet is heavily censored. While many others simply use them to access things like UK or US television, or to switch the version of Netflix they are using.
If you want to try the VPN service illustrated here, which is one of the few that still works with all the British TV sites it’s called Identity Cloaker.
Depending on the environment and the purpose of a proxy then protocol verification is not always necessary. Indeed this was mostly ignored by earlier proxies and gateways as information was simply tunneled through transparently. Nowadays though there is normally some requirement to identify the protocol being transmitted through the proxy server.
Generic (circuit-level) tunneling, such as SOCKS and (SSL) tunneling, allows any protocol to be passed through the proxy server gateway. This implies that the proxy server does not necessarily understand the protocol and cannot verify what is happening at the protocol level. For example, the SSL tunneling protocol, despite its name, can tunnel /my TCP-based protocol, for example the telnet protocol.
A short-term solution to this is to allow only well-known ports to be tunneled, such as 445 for HTTPS, 563 for SNEWS, and 636 for secure LDAP. See Table 7-1 on page 135 for a list of well-known Web-related protocol ports. A longer-term solution is to be provided by proxy servers that verify the spoken protocol. More intelligence will need to be built into proxy servers to understand even protocols that are merely tunneled, not proxied. This enables proxies to notice misuse, such as exploiting the SSL tunneling to establish a telnet session.
Note that protocols that are proxied at the application level by the proxy server, such as HTTP, FTP, and Gopher, cannot be exploited as above because no direct “tunnel” is established through the proxy server. Instead, the proxy will fully re-perform the request on behalf of the client and then pass the response back. This is important as it may be necessary for the function to be completed properly. For example it’s common now to stream multimedia or video through the servers and these need to function on the specific ports. You won’t be able to stream things like the BBC TV output through this site without some sort of protocol verification taking place.
This ensures that the protocol is a legitimately allowed protocol. ‘ However, the Gopher protocol, or rather Gopher URLs, can be used to fool the proxy to make requests using other protocols by crafting special malicious URLs that convert to the language used by some other protocol.
Common Security Holes in Server Software can be read about on this blog and particularly there are Trojan horses disguised as Gopher URLs. If limiting to well-known ports is not acceptable (there are a number of servers out there running on non-standard ports), it is recommended to at least [9106/e ports that deﬁnitely should not be allowed an SSL tunnel to. Among these are ports known to be dedicated for other purposes, such as the telnet and SMTP ports (23, 25, respectively). Some proxy server software may in fact have a built-in ﬁlter for these ports and automatically disallow Gopher requests to them.
When most network administrators talk about network attacks most are referring to those from outside their networks. However the reality is that those originating inside the network are not only more common but potentially much more damaging too. Internal attacks represent the vast majority of attacks on network infrastructure. They certainly can be extremely damaging and often much more challenging to find. One factor that aggravates the situation are company insiders having extensive working knowledge of security controls and considerable time to plan an assault. There is less chance to detect those initial scanning and fingerprinting phases that outside attackers need to do. The insiders can leverage the valid access they already have to gain additional access to systems. There’s huge potential for both social engineering and gaining additional information and privileges from within.
There is no doubt that internal attacks are more challenging to detect than those which originate from outside the network. It is also surprising that company’s often underpay these attacks and in many cases simply ignore them until it’s too late.
This occurs when organizations aren’t monitoring the interior as significantly as the outside. An internal assault might be the consequence of an employee progressively accumulating privileged accessibility and info over a time period of years or even decades.
The internal infrastructure may be opened up to threats from uned ucated or unsuspecting employees. Users could compromise internal security via the installation of firewall beating Peer to Peer file sharing and instant messenger applications. Some P2P applications are packed with spyware or attributes that silently allow the sharing of the whole hard drive. There are also many threats from the many proxies and VPNs that can be installed. Even if these VPNs are simply being used for a relatively benign activity like watching the BBC – check this post, it still represents a huge drain on available bandwidth and speed of the network.
Plus there are of course many network aware instant messengers, like AOL Instant Messenger, may be utilized to cut through any open port on a corporate firewall. Modern viruses are accompanied by many attack payloads that may open a system for the carrying. L/lost non technical customers might be unaware they’re creating a gaping security hole by going about their daily activity.
An IDS on the internal side may be utilized to discover both intentional domestic intentions and corporate policy violations. They can discover the signature of the majority of PZP tools, improper Internet use, and instant messengers. This is in addition to the anticipated intrusion monitoring capacity. These capabilities make an IDS an extremely strong security application. You can even make sure that you keep updating the system to spot known threats more easily. For instance if you detect a large number of attacks coming from a specific country – say Germany then configure alerts when connections are attempted from a German IP address or proxy.
The line between external and internal is increasingly obscured by corporate partner- ships as well as extranets that enable them. An attacker can jump through one part of the extranet to another, which makes the origin of an attack difficult to differentiate. As increasingly more internal security breaches are discovered, organizations will seek to enhance internal security in the future.
Orchestrating an Attack This section serves as a concise introduction to the kinds of suspicious traffic that you may encounter when using Snort. It’s by no means an effort to be all inclusive or detailed. There are many resources, both in print and on-line related to suspicious traffic analysis. In case you’ve however to develop an intensive signature analysis expertise, this section Will assist you concerning know the various genres of assault and also their associated intent. A number of phases in orchestrating an assault are generic enough that they employ to many network based attacks. If hackers are randomly looking for systems or targeting a specic firm. They follow the tried and true methodology.
Following the first planning and reconnaissance legwork is complete, the upcoming logical step is to make use of accumulated info and assault the network. The traffic generated by strikes may take numerous different forms. Everything from the remote exploitation code into questionable normal traffic may signify an attempted assault which needs action. Denial of Service A Denial of Service assault is any attack that disrupts the use of a system in order that legitimate users can no longer access it. DoS attacks are possible on most network equipment, including routers, servers, firewalls, remote access machines, and almost every other network source. A DOS attack may be specific to the service, like in a FTP assault, or even an entire machine. Many times the attacks are against commercial targets or to access useful resources. Many attacks are simply to enable installation of rogue services such as VPNs or FTP which are then used to either store data or to access resources like UK TV abroad like this.
The types of Denial of service attacks are indeed varied and operate on a wide range of targets. However they might be separated into two unique categories that relate to intrusion detection: source depletion and malicious packet strikes. Malicious packet DoS attacks work by sending abnormal visitors to the host to call the service or host to crash. Crafted packet DoS attacks happen when applications isn’t correctly coded to handle abnormal or irregular traffic. Frequently out, of spectrum traffic may cause applications to respond unexpectedly and crash. Attackers may utilize DoS attacks of crafted packages to bring down Intrusion Detection Systems too, even well developed ones like Snort. Additionally to out, of specific range traffic, malicious programs can contain payloads which create a system to crash. A packet payload is input to a service.
In any circumstance whether it’s an application or network enabled device if the input isn’t correctly checked, the application can be DoS’ed. The Microsoft FTP DOS attack demonstrates the broad selection of DoS attacks available to black hats from the wild. The initial step in the assault is to initiate a legitimate FTP link. The attacker then issues a command with a wildcard sequence. Inside the FTP Server, a function that processes wildcard sequences in FTP controls doesn’t allocate enough memory when performing pattern matching. It’s possible for the attackers command containing a wildcard order to cause the FTP service to crash. This particular attack like many including the Snort lCl/lP DoS, are just two samples of the countless thousands of potential Denial of service attacks which are possible and accessible for attackers. The service can then be used to install malware or other code which are then used for other purposes. As mentioned above they are often used as hosts for VPN services which are used to watch British TV overseas or other video streaming functions.
The other means to deny service is through source depletion. A source depletion DoS attack functions by flooding a service with so much regular traffic that legitimate users can’t access the service. An attacker inundating an agency with regular traffic may exhaust finite resources like bandwidth, memory, and processor cycles.A classic memory resource exhaustion attack which will bring down a device is a SYN flood. A SYN flood takes advantage of the Transmission Control Protocol 3, way handshake. The handshake starts off with the customer sending a Transmission Control Protocol SYN pack- et. The host then sends the SYN ACK in response. The handshake is finished when the customer responds with an ACK.
In case the host doesn’t get returned by the ACK, the host sits idle and waits with a session available. Every open session consumes a certain quantity of memory. If enough three, manner handshakes are initiated, the host consumes all available memory waiting for ACKs. The traffic created from the SYN stream is normal in all other respects.
Overall ICMP has been viewed as quite a harmless and perhaps even trivial protocol. However that all changed with the rather nasty Loki. In case you didn’t know Loki is from Norse mythology and he was the god of trickery and mischief. The Loki exploit is well named and seeks to exploit the hither to benign ICMP protocol. ICMP is intended mainly to inform users of error conditions and to make very simple requests. It’s one of the reasons intrusion analysts and malware students tended to ignore the protocol. Of course it could be used in rather obvious denial of service attacks but they were easily tracked and blocked.
However Loki changed that situation as it used ICMP as a tunneling protocol as a covert channel. The definition of a covert channel in these circumstances is a transport method used in either a secret or unexpected way. The transport vehicle is ICMP but Loki acts much more like a client/server application. Any compromised host that gets a Loki server instance installed can respond to traffic and requests from a Loki client. Which would also work if the client was spoofing their IP address to watch something like Netflix for instance – see this. So for instance a Loki server could respond to a request to display the password file to screen or file. That could then be possibly captured and cracked by the owener of the Loki client application.
Many intrusion detection analysts would have simply ignored ICMP traffic passing through their logs. Mainly because it’s such a common protocol but also an such an innocuous one. Of course well read analysts will know treat such traffic with heightened suspicion, Loki really has changed the game for protocols like ICMP.
For those of us who spend many hours watching traffic Loki was a real eye opener. You had to check those logs a little more carefully especially to watch out for those strange protocols being used in a different context. There’s some more information on these attacks hidden on this technology blog – http://www.iplayerabroad.com/using-a-proxy-to-watch-the-bbc/. It can take some finding though !!
