Hackers spreading Locky ransomware by uploading infected .SVG images on Facebook Messenger

What is Locky Ransomware ?

The name of this ransomware is LOCKY. What is Locky ? it actually denotes one of the today’s prevalent ransomware families. It was discovered in the mid-February 2016. This file-encrypting epidemic proved to be sophisticated enough to fly under the radar of conventional anti-malware defense. However, Locky is one of the most preferred malicious software used by hackers. 

Who Discovered ?

Bart Blaze, a very well known reputed security researcher first discovered this type of ransomware attack which is being conducted via Facebook Messenger. Later, Peter Kurse, another security researcher with extensive experience in investigating cyber-crimes confirmed the news to reporters.
Bart Blaze wrote in his personal blog :
 “As always, be wary when someone sends you just an ‘image’ – especially when it is not how he or she would usually behave”. 
And Facebook has released the following statement in response to the discovery:
 “We maintain a number of automated systems to help stop harmful links and files from appearing on Facebook, and we are already blocking these ones from our platform. In our investigation, we determined that these were not, in fact, installing Locky malware—rather, they were associated with Chrome extensions. We have reported the bad browser extensions to the appropriate parties”. 

How does it spread ?

To spread Locky ransomware hackers are using a downloader software called Nemucod. This downloader is being used by hackers to help the ransomware bypass Facebook security by pretending to be a .svg image file. Hackers is now delivering this downloader software Nemucod through Facebook Messenger. 
What is .svg image file ? How hackers spread ransomware through it ? SVG extension file is scalable vector graphics file. It’s based on XML (Extensible Markup Language). So, it’s very easy to implement a set of codes of any harmful programs in it.
However, in this case hackers has embedded JavaScript. When you access this infected vector image file (SVG) then this java-script directs you to a site that seems to be YouTube’s landing page. But, actually it is not real Youtube’s homepage. It’s a clone site developed by hackers. If you look in the url then you will find that it’s 100% different.
However, after loading the fishing site you’ll be requested to download & install a codec so that the desired video could be played. This codec is presented in Chrome extension. If you install this codec chrome extension then the attack shall be distributed to other friends of you via Facebook Messenger. And at the same time this chrome extension will install Nemucod downloader, and instantly Locky will be installed into your system via Nemucod downloader. After that your all personal files on PC will be encrypted (locked) by Locky & it’ll demand some money via Bitcoin to decrypt them.

mathematics behind chess

Is there any relationship between supposing numerically and supposing in the round of Chess? At the end of the day, should a man having a dynamic personality in Mathematics turned out to be essentially a decent Chess player have aptitudes in Mathematics?  It is important to call attention to that because of the subject intricacy, our endeavors will be to clarify essential attributes of both  Science and Chess which have been postured by surely understood Mathematicians and Chess players. In like manner, we are not keen on uncovering truths, for instance, from the Theory of Knowledge, Psychology, Epistemology or going further into the specialized and complex parts of Chess.  In the first place, let us analyze a few characteristics of Mathernatics.  Individuals having poor involvement in Mathematics trust that knowing how to include, subtract, increase or separation empowers them to say that they could ace Mathematics. Others having some aptitude in performing fa

The ganges dolphins & crocodiles are also living in the canals of Sundarbans. Chital is a one kind of spotted deer living in this forest.
