Copy paste from that article, excluding screenshots:
"Yesterday, I’ve posted about the Opera Next (Opera 15) which is the first version of the Opera after integrating with Chromium. This new version 15 has so many cuts and shaves. You will certainly feel the direct chromium look and design. However, You can install flood of Chrome extensions in Opera from Chrome Web Store. In addition, You can also install extensions offered by Opera.

Opera said in a Blog post,

At this point, Opera 15 (available as Opera Next) supports a subset of the Chromium extension APIs — with more to come.
According to this statement, Currently you can install Chrome Extensions in Opera but all not going work. You can expect more functionality when stable version released.

Steps Install Chrome Extensions in Opera



1. Go to Chrome web store to install any chrome extensions in opera.(or Visit our 25 best Chrome Extensions and apps page http://www.spicytricks.com/tips/chrome-extensions-apps) For example, I”ve opened the Google URL Shortener extension page. But in Opera there is no Add to Chrome (ie: Download) button.



2. To install extension you need download button. To fix this issue, you have to install “Download Chrome Extension” from Opera add-ons page. When you install that Add-on, Opera will notify you that ” Extension was disabled because it is from unknown source. Go to extensions manger to enable it”. So Go to extension manger (Press CTRL + SHIFT + E), and click install button. Now you can see the Chrome store icon beside the address bar of Opera.

3. Now Visit the Chrome extensions page and click the Chrome Store Icon in the Opera to install any extension.

 
 

4. Also note that same notification will arise for all extension installation, go to extension manger to enable installed extensions from Chrome Web Store..

Note that You can’t download many Of the Extensions. Here (http://www.spicytricks.com/tips/chrome-extensions-apps) is the list of working Chrome Extensions to install in opera."


Karma!

By the way, I'm little bit surprised that AVG resolved this instead of Kaspersky. 

 

A little surprised...?




I was SHOCKED - especially for I really do NOT like AVG! BUT fair is fair... Offline boot scan beats Kaspersky (which, btw, keeps crashing on my Win 7 system... Avast, avast, avast - I keep telling everyone :>)

Karma,

Nice done D., your friend is really lucky.

Confirmed again.

Delving Deeply Into a Bitcoin Botnet

Bitcoin is a virtual decentralized currency that was created in 2009 by developer Satoshi Nakamoto, who described the currency in a paper. Recently Bitcoin has gotten lots of attention. In early 2013, the prices reached a high of US$265 per Bitcoin. The following chart shows the currency’s historical price:

Because Bitcoin is a virtual currency and independent of any financial institution, many vendors accept Bitcoins as payments.

Bitcoins are generated through a process called mining. Every transaction is in the form of block that is broadcasted to all the nodes on the network. Nodes try to find a difficult proof of work that involves finding a value which when hashed with an algorithm such as SHA-256 gives output that contains a number of zero bits. Once a node finds such a hash, the user is rewarded with new Bitcoins.

Because mining requires enormous processing power, the concept of “pooled” mining allows lots of people to work together to find a hash value. They all work together by sharing their resources. Once a hash has been generated by any user, they all split the created Bitcoins.

The current jump in Bitcoin price suggests that cybercriminals are paying attention. With pooled mining, it is easier for botnet owners to install Bitcoin mining clients on various systems working together to generate Bitcoins for the botnet masters.

In our recent analysis of botnets, we found a couple of samples that were communicating to various online Bitcoin mining services over the Stratum protocol:




We also saw a couple of samples using JSON/RPC calls:




And communication with a control server:




It is clear that this bot is sending various information to the control server back and receiving commands from the server.

Our analysis found that this botnet uses ufasoft Bitcoin mining software. All the required files are embedded inside the resource section of the .exe, so unlike other botnets no extra download is required.




The following screenshot shows malicious files getting unpacked in memory and running there.




The botnet also dropped a couple of required files for Bitcoin mining under a temp/{random name} folder:




After that the botnet launches the file responsible for Bitcoin mining:




Note that the file has a fake description: “Malwarebytes Anti-malware.”

This bot can be installed on a victim’s system through various methods: drive-by downloads, download via botnet, etc. Once run, this bot registers with various online pooled mining services with the attacker-supplied user name and password, so the attacker gets Bitcoins credited to his or her own account:




We found one person selling an entire botnet kit on one of the underground forums for just a few dollars:




We also found that the sample we got is the same as shown in the preceding forum post.

Here are couple of screenshots showing the control panel of the bot.

Commands:




Bitcoin settings:




Botnet summary:




Statistics:




Bitcoin has recently gotten lots of media coverage because of the price it has attained during the last few months. We believe that this upward price trend will continue. With this bot, attackers are seeking new sources of income. They are quick to obtain the latest code as soon as it’s available.

McAfee customers are protected against this threat by IPS signature ID:0x4880b300_BOT_Bitbot_Activity_Detected.
