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.

Monitors are viewed as uninvolved and safe to hacks. Be that as it may, a scientist can't help disagreeing with this basic idea. The main thing a monitor does is get information and transform it into pixels. Yet, to do as such, the monitor requires a little PC. This 'little PC' is powerless to hacks.  A security research bunch figured out how to hack into a monitor and control showed content, not to mention spy on the client. It would be a bad dream if the monitor were betrayed you in such a way. The programmer would have admittance to everything that showcases on your monitor including exceptionally secret stuff, for example, passwords to different locales.  Ang Cui, close by some of his associates displayed the hack amid the Def Con hacking gathering in Las Vegas a week ago.

My Sri Lanka Tour - "Sri Lanka and its Spices"

Sri Lanka is known for its spices. I decided to visit some spices garden during my stay there. I had informed our guide Mr. Sunil Gamage to ensure that visiting spices garden should be in our sightseeing list. He managed a visit to Pinnawela Spices garden on our way to Kandy.   Spices are elements of history. They were one of the chief trades during the period of conquering. In many empires cinnamon and cloves are honoured as currency. Countries like Sri Lanka and Indonesia are long regarded as fertile land for growing spices. Mainly Arab traders controlled this eastern spices trade until the 15th century. Then Europeans reached the shores of Asia, took control of the trade of spices from the Arab’s hands. They changed the socio cultural scenario of Asia for good.   Some pictures of the Pinnawela Spices Garden:      1.   Cardamom   2 .   Peeper      3.  Cocoa    Spices are mainly grown in hilly parts of Sri Lank with major gardens situated around Matale.
