HTTP/2 - What is it and what is new?

9 Things To Expect

1. Same HTTP APIs
Making HTTP/2 succeed means that it has to work with the existing Web. So, this effort is about getting the HTTP we know on the wire in a better way, not changing what the protocol means.


2. Cheaper Requests
The Web performance community’s mantra is “avoid HTTP requests” because HTTP/1 make them expensive. This has given rise to techniques like inlining, concatenation and spriting to reduce the number of requests on a page.

With HTTP/2, these techniques shouldn’t be necessary


3. Network- and Server-Friendliness
HTTP/2 allows the use of a single connection per host, and encourages sites to consolidate their content on one host where possible.


4. Cache Pushing
HTTP/2’s “server push” allows a server to proactively send things to the client’s cache for future use.

5. Being Able to Change Your Mind
HTTP/2 adds the RST_STREAM frame to allow a client to change its mind; if the browser navigates away from a page, or the user cancels a download, it can avoid having to open a new connection without wasting all of that bandwidth.

6. More Encryption
HTTP/2 doesn’t require you to use TLS (the standard form of SSL, the Web’s encryption layer), but its higher performance makes using encryption easier, since it reduces the impact on how fast your site seems.

7. No More Text
One of the nice things about HTTP/1 is the ability to open up telnet, type in a request (if the server doesn’t time out!) and then look at the response. This won’t be practical in HTTP/2, because it’s a binary protocol. Why?

While binary protocols have lower overhead to parse, as well as a slightly lighter network footprint, the real reason for this big change is that binary protocols are simpler, and therefore less error-prone.

8. It’ll Take Some Time to Get it Right
HTTP/2 isn’t magic Web performance pixie dust; you can’t drop it in and expect your page load times to decrease by 50%.

It’s more accurate to view the new protocol as removing some key impediments to performance; once browsers and servers learn how and when to take advantage of that, performance should start incrementally improving.

9. HTTP/3 and Beyond
HTTP/1.x has lasted for more than fifteen years; why would we be even considering HTTP/3 before HTTP/2 is done?

One of the big reasons that HTTP/2 took so long to get to is that upgrading the protocol in the deployed infrastructure is really hard; there are lots of boxes out there that assume HTTP/1 will never change.

So, if the transition from HTTP/1 to HTTP/2 goes well, it should be a lot easier to introduce the next version, because we can use the same mechanism that we used for the first big hop.

Ever heard of EQUATIONDRUG? - It has nothing to do with Drugs, it is an attack platform to control compromised computers.


We need to install software from a valid install CD but, if that is compromised then how can we protect.

Researchers at Kaspersky Lab have uncovered a cyberespionage group that has been operating for at least 15 years and has worked with and supported the attackers behind Stuxnet, Flame and other highly sophisticated operations. 


Once a PC is compromised, the attackers install the EQUATIONDRUG attack platform, which is the main component from which further operations run. The platform includes a variety of modules and has an analog in another platform called GRAYFISH, which is an updated version of the attack framework.

Countries targeted by this group include Russia, Syria, Iran, Pakistan, China, Yemen, Afghanistan, India but also US and UK, between and several others.

GRAYFISH is the most highly evolved version of its attack infrastructure. The attackers began using this platform about seven years ago and have been improving it as they go. - See more at: 


The trump card for the Equation Group attackers is their ability to inject an infected machine’s hard drive firmware. This module, known only by a cryptic name – “nls_933w.dll”, essentially allows the attackers to reprogram the HDD or SSD firmware with a custom payload of their own creation. 


Fanny creates a hidden storage area on the stick. If it infects a computer without an internet connection, it will collect basic system information and save it into the hidden area of the stick. Later, which a stick containing hidden information is plugged into a computer infected by Fanny having an Internet connection, the data will be scooped from the hidden area and sent to the C&C. 


Another incident included an installation CD for Oracle software that included a Trojan dropper for the Equation Group’s malware. This is a tactic that, through the Edward Snowden documents, has been attributed to operations conducted in the past by the National Security Agency.

The C&C infrastructure includes hundreds of domains in a number of countries, including the United States, the UK, Italy and Germany. 

“The scariest thing about them is that we don’t have any samples from 2014. So somewhere in 2013 these guys went off the radar,” he said. “We have no idea what they did in 2014, which is very, very scary.” -

After Paypal , it is GoDaddy - CSRF Vulnerability



In OWASP top 10 list - CSFT was #8

In December, a CSRF vulnerability that would have enabled a hacker to completely bypass the authentication system in PayPal was patched.  Now it is GoDaddy.

What surprises is websites belonging to companies that either rely  on eBusiness or play a crucial role seem to have these vulnerabilities


From the Article

Security researcher Dylan Saccomanni, while managing an old domain in GoDaddy, noticed that there was absolutely no CSRF protection at all on many GoDaddy DNS management actions.

While Saccomanni said that it was “somewhat difficult” to reach GoDaddy’s security, he eventually got through via Twitter from @GoDaddyHelp. Once notification was made, it only took one day for the web hosting giant to fix the flaw.

The bottom line is that an attacker could use the CSRF vulnerability to de facto take over a domain from a victim.

“They don’t need sensitive information about the victim’s account, either—for auto-renew and nameservers, you don’t need to know anything,” Saccomanni said. “For DNS record management, all you need to know is the domain name of the DNS records.”

A chain is only as strong as its weakest link, - You (Example :- JP Morgan) will get hacked even if you spend $250 Million every year


There are two thinks I always remember


  1. A chain is only as strong as its weakest link (So, know what you want to protect and then find the the right method (simple is always best) to protect it)
  2. Security is Part philosophy (Sometimes what you think and believe may not be the best method of protection so, listen well and adapt quickly)


From the Article

Big corporations like JPMorgan spend millions — $250 million in the bank’s case — on computer security every year to guard against increasingly sophisticated attacks like the one on Sony Pictures. But the weak spot at JPMorgan appears to have been a very basic one.


JPMorgan’s security team had apparently neglected to upgrade one of its network servers with the dual password scheme (2 Factor) , the people briefed on the matter said. That left the bank vulnerable to intrusion.

If you shopped in STAPLES - Keep an eye on your credit card activity



Target is old news - STAPLES is the latest - 1.2Million Credit Card information lost



From the Article

“At 113 stores, the malware may have allowed access to this data for purchases made from August 10, 2014 through September 16, 2014,” 


While the Staples breach is dwarfed in the number of lost records by Home Depot and Target, the common link is poorly secured point-of-sale systems and effective malware targeting those platforms and stealing payment card data before it is encrypted.

SS7 Vulnerability - Be careful about what you say on your Cell Phone,






From the Article

The German researchers found two distinct ways to eavesdrop on calls using SS7 technology. 


  • In the first, commands sent over SS7 could be used to hijack a cell phone’s “forwarding” function -- a service offered by many carriers. Hackers would redirect calls to themselves, for listening or recording, and then onward to the intended recipient of a call. Once that system was in place, the hackers could eavesdrop on all incoming and outgoing calls indefinitely, from anywhere in the world.

  • The second technique requires physical proximity but could be deployed on a much wider scale. Hackers would use radio antennas to collect all the calls and texts passing through the airwaves in an area. For calls or texts transmitted using strong encryption, such as is commonly used for advanced 3G connections, hackers could request through SS7 that each caller’s carrier release a temporary encryption key to unlock the communication after it has been recorded.
