Do you know?-More than 360 Million accounts credentials and around 1.25 billion email addresses are put up on sale on the online Black Market by Hackers worldwide.

This is the world’s biggest cyber attack ever.

A company in London named ‘Hold Security’ researched and found this huge size of data .

Only one of the hacker attack stole more than 105 million records, which is a single largest data breach in the history.

“These credentials can be stolen directly from your company but also from services in which you and your employees entrust data. In October 2013, Hold Security identified the biggest ever public disclosure of 153 million stolen credentials from Adobe Systems. One month later we identified another large breach of 42 million credentials from Cupid Media,” the firm said.

The firm took three weeks to collect the data. Firm tracked over 300 million abused credentials that were not disclosed publicly (that is over 450 million credentials if one counts the Adobe find).

“But this month we exceeded all expectations. In the first three weeks of February we identified nearly 360 million stolen and abused credentials and 1.25 billion records containing only email addresses. These mind boggling numbers are not meant to scare you and they are a product of multiple breaches which we are independently investigating. This is a call to action,” it added.

“The sheer volume is overwhelming,” said Alix Holden, chief information security officer of Hold Security.

Email addresses include all the major providers like Google, Microsoft and Yahoo. Many non-profit organizations and all Fortune companies had been affected.

This is the biggest data breach after the Adobe one.

Number of Malvertising attacks are appeared to be increasing day by day, even top websites fall victim to such kind of attacks - YouTube is to be the latest popular organization affected by malicious ads.

Security experts from Bromium have discovered that the cyber criminals were distributing a malware via YouTube ads.

According to researchers,  malicious ads attempt to exploit vulnerabilities in outdated Java.  It loads different malicious jar file, to ensure the exploit is compatible with the installed java version.

The Exploit kit used in this attack "Styx Exploit Kit" which was the same one used by cybercriminals to infect users of toy maker Hasbro.com.

If the user's machine is having vulnerable plugins, it will exploit the vulnerability and drops a Banking Trojan known as "Caphaw".  Researchers say they are working with Google Security team.

ABSTRACT

Readers, there are numerous reasons... It is well known that the Internet is an unmanaged a decentralized network, running under a set of protocols, which are not designed to ensure the integrity and confidentiality of information and access controls.

There are several ways to breach a network, but these ways do nothing more than take advantage of flaws within network protocols and services.

CONCEPTS

IPTABLES is an editing tool for packet filtering, with it you can analyze the header and make decisions about the destinations of these packets, it is not the only existing solution to control this filtering. We still have the old ipfwadm and ipchains, etc.

It is important to note that in Gnu / Linux, packet filtering is built into the kernel. Why not configure your installation in accordance with this article, since most distributions come with it enabled as a module or compiled directly into the kernel.

CONCLUSION

I hope to help you in configuring your network security and remind you to choose only the best options available.

Allow me to add a few Advantages of using your firewall. Be sure to Block unknown and unauthorized connections. You can specify what types of network protocols and services to be provided and you may control the packets from any untrusted services... Your firewall also allows blocking websites with URL filters, access control, access logs for reports by user, protecting the corporate network through proxies, and Network Address Translation (NAT). Control services that can either be executed or not, on the network allowing for high performance in their duties with easy administration and reliability.

A hacker who calls himself "Eugene Belford" (A character from the movie "Hackers" )has hacked the EC-Council website - an organization that offers Certified Ethical Hacker(CEH)

"Owned by certified unethical software security professional" The defacement message reads.

He has also put in the deface page documents proving that "Edward Snowden" attended the CEH classes in India.

A spokesman from CSPF (Cyber Security and Privacy Foundation) says, it appears to be hackers used DNS hijacking attack to deface the website and possible gain access to their email.

Another CEH certified professional says he was not satisfied with EC Coucil  Training. He says though the course material is good and certification is recognised worldwide, the trainers from francisees of EC Coucil do not know hacking and they are not competent to take CEH classes.

Update: Sometime after this news was posted the hacker edited the deface page with this extra text.

"Defaced again? Yep, good job reusing your passwords morons jack67834#

 owned by certified unethical software security professional

Obligatory link: http://attrition.org/errata/charlatan/ec-council/

-Eugene Belford

P.S It seems like lots of you are missing the point here, I'm sitting on thousands of passports belonging to LE (and .mil) officials "

It might be that the attacker has gotten access to the emails of EC Council and hence all the email correspondence of the Law Enforcements and Military officials might be compromised also.

In this Modern Era everyone knows that his/her latest mobile can be hacked by hackers but now The sim card hacking flaw was discovered by German programmer Karsten Nohl, who has informed mobile operators of the potential danger.

After that all the Mobile phone users have been put on an alert that their sim cards can be hacked anytime which leads to fraud and soaring premium rate bills.

On the other hands, if we talk about the mobile operators then they says that they already aware about this flaw and taking steps to patch the flaw before customers are hit.

Worldwide Mobile Phones are Major source to be used in accessing online banking and other sensitive personal information and if the discovered flaw will be used by Hackers can make a privacy disaster, this flaw also makes some noise for the mobile customers who use their smartphones to pay bills and transfer money.

The security flaw is due to aging sim card security technology, which has struggled to keep up with high-tech smartphones such as the iPhone and Samsung’s Galaxy S4.

Flaw Researcher (Karsten Nohl) says something about his Flaw:

“Give me any phone number and there is some chance I will, a few minutes later, be able to remotely control this SIM card and even make a copy of it,”

The hack works by manipulating a coding technology used by operators to update sim cards. Properly equipped, a hacker can send a code to a sim card to gain access to a phone’s systems, from where fraudulent activity can be perpetrated.

Nohl said that a quarter of all sim cards he tested could be hacked.

However, the international umbrella mobile operator organisation, the GSMA, said that the flaw was limited to a minority of sim cards and that newer sim cards may not be affected.. It said that it had advised operators of the security risks involved.

Lightbeam is a Firefox add-on that enables you to see the first and third party sites you interact with on the Web. Using interactive visualizations, Lightbeam shows you the relationships between these third parties and the sites you visit.

Using interactive visualizations, Lightbeam enables you to see the first and third party sites you interact with on the Web. As you browse, Lightbeam reveals the full depth of the Web today, including parts that are not transparent to the average user. Using three distinct interactive graphic representations — Graph, Clock and List — Lightbeam enables you to examine individual third parties over time and space, identify where they connect to your online activity and provides ways for you to engage with this unique view of the Web.

How Lightbeam Works ::

When you activate Lightbeam and visit a website, sometimes called the first party, the add-on creates a real time visualization of all the third parties that are active on that page. The default visualization is called the Graph view. As you then browse to a second site, the add-on highlights the third parties that are also active there and shows which third parties have seen you at both sites. The visualization grows with every site you visit and every request made from your browser. In addition to the Graph view, you can also see your data in a Clock view to examine connections over a 24-hour period or in a List view to drill down into individual sites.

How You Can Use Lightbeam to Help Us Illuminate the Inner Workings of the Web ::

As a part of Lightbeam, we're creating a big-picture view of how tracking works on the Internet, and how third-party sites are connected to multiple other sites. You may contribute your data to our crowdsourced directory by simply turning on the share switch within the add-on. To disable crowdsourcing, you can turn it off at any time. You can view your local data stored within Lightbeam at any time, or save your data by clicking the "Save" button under the data section on the left side of the add-on.

How is my information stored? ::

As a default, all info generated and used for Lightbeam’s visualizations and features are only stored locally on your computer. You can save a copy of your connection history at any time, which is also where you can see the specific data collected by the add-on. You may also reset Lightbeam to erase your locally stored connection history, disable it to stop data collection or uninstall it to instantly remove all locally stored data related to Lightbeam.
