About Ransomware !!!!
What Is Ransomware?
Ransomware is the fastest-growing malware threat today and is already an epidemic. According to a U.S. government interagency report, an average of more than 4,000 ransomware attacks have occurred daily since January 2016.
Cryptocurrency is an alternative digital currency that uses encryption to regulate the “printing” of units of currency (such as bitcoins) and to verify the transfer of funds between parties, without an intermediary or central bank.
Ransom amounts are typically high, but not exorbitant. For example, demands for individuals typically range from $300 to $600, while larger organizations will typically pay more. In 2016, a South Carolina school district paid an estimated $10,000 ransom and a California hospital paid approximately $17,000 to cybercriminals.
These amounts quickly add up — more than $200 million in the first three months of 2016, according to the U.S. Federal Bureau of Investigation (FBI). This characteristic of ransomware is by design, in an effort to get victims to simply pay the ransom as quickly as possible, instead of contacting law enforcement and potentially incurring far greater direct and indirect costs due to the loss of their data and negative publicity.
Understanding How Ransomware Operates:
Ransomware is commonly delivered through exploit kits, waterhole attacks (in which one or more websites that an organization frequently visits is infected with malware), malvertising (malicious advertising), or email phishing campaigns.

Once delivered, ransomware typically identifies user files and data to be encrypted through some sort of an embedded file extension list. It’s also programmed to avoid interacting with certain system directories (such as the WINDOWS system directory, or certain program files directories) to ensure system stability for delivery of the ransom after the payload finishes running. Files in specific locations that match one of the listed file extensions are then encrypted. Otherwise, the file(s) are left alone. After the files have been encrypted, the ransomware typically leaves a notification for the user, with
instructions on how to pay the ransom
There is no honor among thieves. Although an attacker will usually provide the decryption key for your files if you pay the ransom, there is no guarantee that the attacker hasn’t already installed other malware and exploit kits on your endpoint or other networked systems, or that they won’t steal your data for other criminal purposes or to extort more payments in the future.
During an Attack: Detect, Block, and Defend:
If your organization is under attack, fast and effective incident response is required to limit any potential damage. The specific action steps and remediation efforts to be undertaken will be different for each unique situation. However, the time to learn the breadth and extent of your organization’s incident response capabilities is not during an attack! Your incident response efforts
should be well understood and coordinated — which is accomplished before an attack — and well documented and repeatable, so that you can reconstruct an incident after an attack and identify lessons learned and potential areas for improvement.
A key component of effective incident response that is often overlooked is information sharing, which includes the following:
» » Communicating timely and accurate information to all stakeholders: Pertinent information needs to be provided to executives in order to ensure adequate resources are committed to response and remediation, critical and
informed business decisions can be made, and appropriate information is, in turn, communicated to employees, law enforcement, customers, shareholders, and the general public.
» » Automatically sharing new security intelligence throughout the architecture: Bringing together critical data from disparate systems, such as security information and event management (SIEM), threat intelligence, and sandboxing
tools, enables the incident response team to quickly surface and effectively triage high-impact security incidents. For example, if a new malware payload is detected on an endpoint, it should automatically be sent to a cloud-based threat intelligence platform for analysis in order to find and extract any indicators of compromise (IoCs). Then new countermeasures should automatically be deployed and enforced.
After an Attack: Scope, Contain and Remediate
Important actions after an attack has ended include the following:
» » Resuming normal business operations, including restoring backups and reimaging systems, as necessary
» » Collecting and preserving evidence for law enforcement and auditing purposes
» » Analyzing forensic data to predict and prevent future attacks, for example, by identifying related domains and malware with the associated IP addresses, file hashes, and domains
» » Performing root cause analysis, identifying lessons learned, and redeploying security assets, as necessary Predictive threat intelligence enables a proactive security posture by enabling your organization to see the C2 infrastructure that attackers are leveraging for current and future attacks, and thereby always stay ahead of the threat.

Ransomware is the fastest-growing malware threat today and is already an epidemic. According to a U.S. government interagency report, an average of more than 4,000 ransomware attacks have occurred daily since January 2016.
Ransomware is malicious software (malware) used in a cyberattack to encrypt the victim’s data with an encryption key that is known only to the attacker, thereby rendering the data unusable until a ransom payment (usually cryptocurrency, such as Bitcoin) is made by the victim.
Cryptocurrency is an alternative digital currency that uses encryption to regulate the “printing” of units of currency (such as bitcoins) and to verify the transfer of funds between parties, without an intermediary or central bank.
Ransom amounts are typically high, but not exorbitant. For example, demands for individuals typically range from $300 to $600, while larger organizations will typically pay more.

This characteristic of ransomware is by design, in an effort to get victims to simply pay the ransom as quickly as possible, instead of contacting law enforcement and potentially incurring far greater direct and indirect costs due to the loss of their data and negative publicity.
Ransom amounts may also increase significantly the longer a victim waits. Again, this is by design, in an effort to limit a victim’s options and get the victim to pay the ransom as quickly as possible.
Ransomware is not new virus.

Oh! no something has gone wrong, A problem has occurred and system can't recover. Please contact a system administrator.
Oh! no something has gone wrong, A problem has occurred and system can't recover. Please contact a system administrator.
There are many reason for that problem. When you have to use VMware (kali linux) then check your storage space.....
If storage space is not enough then this problem face by many people.
But if you have base system (kali linux) then check your log of the system and you have to identify the issue
How that problem occured ????
1. Not enough space and you forcefully try to install the package any one.
2. This issue is occured when your gnome package having some problem or gnome session problem.
So, try some steps to recover this problem like,
Whenever you get this screen....................
Then you have to type " CTRL + ALTR + F1 "
You got root screen(You get the everything!!!!!!). Which is useful to recover the system.
Firstly, Connect with wifi network or ethernet
using some commands......
1.type in terminal "iw dev" // this command is find the available wifi adapters
2.type "ip link show wlan0 " // check device status
3.type "ip link set wlan0 up" //Bring up the wifi interface
4.type "iw wlan0 scan" // Scan to find wifi networks
5.type "wpa_passphrase blackMOREOps >> /etc/wpa_supplicant.conf" //generate a wpa/wpa2 configuration file
6.type "cat /etc/wpa_supplicant.conf" // you got the username and password from this file
7.type " wpa_supplicant -B -D wext -i wlan0 -c /etc/wpa_supplicant.conf " // connect to WPA/WPA2 network
8.type "dhclient wlan0" // Get an ip using this command
"I think!!!!!!!!! you are bored!!!!!!" and you think about ethernet cable RJ45 to get the internet..hahaha!!
after getting connectivity
firstly ,
try this basic command to solve that problem
"apt-get clean && apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y"
if some package missing error got then
check your repository
/etc/apt/sources.list
and try using some diffrent...............
for kali linux 1.x user try this
"
# Regular repositories
deb http://http.kali.org/kali kali main non-free contrib
deb http://security.kali.org/kali-security kali/updates main contrib non-free
# Source repositories
deb-src http://http.kali.org/kali kali main non-free contrib
deb-src http://security.kali.org/kali-security kali/updates main contrib non-free
"
for kali linux 2.x user try this
"
# Regular repositories
deb http://http.kali.org/kali sana main non-free contrib
deb http://security.kali.org/kali-security sana/updates main contrib non-free
# Source repositories
deb-src http://http.kali.org/kali sana main non-free contrib
deb-src http://security.kali.org/kali-security sana/updates main contrib non-free
"
Then type " startx " which is not working in kali linux. but working in backtrack.
So You have to install
"apt-get install x-window-system"
or
"apt-get install x-windows-system"
and then try "startx"...
If you are lucky then got it graphical manner linux
If not then wait for some time to do some steps
"apt-get install xorg"
then try "startx"
If not working .....
then you have gnome problem I think so
You have to try some steps like...
" apt-get remove gnome-core "
and then
reinstall using below step
" apt-get install gnome-core kali-defaults kali-root-login desktop-base "
and then try this steps
" dbus-launch gsettings set org.gnome.desktop.session session-name 'gnome' "
and then
" gsettings get org.gnome.desktop.session session-name 'gnome' "
I think you got graphical manner desktop
If you have some problem then it is gnome session problem
so you try below step
remove gnome-session and
and then
"apt-get install gnome-session-common"
and
"apt-get install gnome-session-fallback"
and then
"reboot"
finally, you have to solved that problem
thank you for visit my blog..........

Futuristic Cicret Bracelet Works Like A Touch-Screen Smart Phone On Your Skin..!!!!
This Cicret bracelet lets you do everything you do on a tablet on your skin with the help of a picture projector or picoprojector.
The picoprojector projects the interface on your arm and when you put your finger on the interface, you stop one of eight long range proximity sensor which sends back information to the processor in the bracelet.
