Researchers Uncover Spying Tool Used by Governments to Hijack all Types of Smartphones #Hacking #Privacy #Spying #Hijacking #Surveillance



Purchasing malware to victimize people is illegal by laws but if the same thing any government official do, then its not!! Yes, the police forces around the World are following the footsteps of U.S. National Security Agency (NSA) and FBI.

Researchers from the Citizen Lab at the Munk School of Global Affairs at the University of Toronto and computer security firm Kaspersky Lab have unearthed a broad network of controversial spyware which is specially designed to give law enforcement agencies complete access to a suspect's phone for the purpose of surveillance.


The malware, dubbed as Remote Control System (RCS), also known as Da Vinci and Galileo, is developed by an Italian company known as Hacking Team, available for desktop computers, laptops, and mobile devices. The latest version of the malware works for all phone including Android, iOS, Windows Mobile, Symbian and BlackBerry devices, but best on Android devices, and can also be installed on jailbroken iOS devices. But even if the targeted iOS device is not jailbroken, the malware uses the famous Evasi0n jailbreaking tool to install the malware easily.

The team of researchers from both Citizen Lab and Kaspersky Lab in collaboration has presented their findings during an event in London. According to the report published, the diameter of the command infrastructure supporting Hacking Team, which sells the RCS to governments and law enforcement, is very vast with 326 command-and-control (C&C) servers running in more than 40 countries.

MALWARE DEVELOPERS - ‘HACKING TEAM’
Hacking Team is a Milan-based IT company with more than 50 employees that has made a totally different place for itself selling "offensive" intrusion and surveillance software to governments and law enforcement agencies in "several dozen countries" on "six continents."

It was a well-known fact for quite some time that the HackingTeam products included malware for mobile phones. However, these were rarely seen,” said Kaspersky Lab experts on the blog post. “In particular, the Android and iOS Trojans have never been identified before and represented one of the remaining blank spots in the story.”


Kaspersky Lab researchers have used a fingerprinting method to scan the entire IPv4 space and to identify the IP addresses of RCS Command & Control servers around the world and found the biggest host in United States with 64 counts of C&C servers. Next on the list was Kazakhstan with 49, Ecuador has 35, UK which hosts 32 control systems and many other countries with a grand total of 326 Command & Control servers.
"The presence of these servers in a given country doesn't mean to say they are used by that particular country's law enforcement agencies," said Sergey Golovanov, principal security researcher at Kaspersky Lab. "However, it makes sense for the users of RCS to deploy C&Cs in locations they control – where there are minimal risks of cross-border legal issues or server seizures."
RCS can be physically implanted on the victim’s device through a USB or SD card, and remotely it can be installed through spear phishing, exploit kits, drive-by downloads or network traffic injection.

Once installed on Apple iOS and Android device, the new module enable governments and law enforcement officers with larger capabilities to monitor victim devices, including the ability to:
  • control phone network
  • steal data from their device
  • record voice E-mail
  • intercept SMS and MMS messages
  • obtain call history
  • report on their location
  • use the device’s microphone in real time
  • intercept voice and SMS messages sent via applications such as Skype, WhatsApp, Viber, and much more.
"Secretly activating the microphone and taking regular camera shots provides constant surveillance of the target—which is much more powerful than traditional cloak and dagger operations," Golovanov wrote.
While, the Android module is protected by an optimizer for Android called DexGuard that made the it extremely difficult to analyze. However, most of the iOS capabilities mentioned above are also available for Android, along with the support for hijacking applications such Facebook, Google Talk, Tencent of China and many more.

The mobile modules for each are custom-built for each target, researchers said. From previous disclosures we have seen that RCS is currently being used to spy on political dissidents, journalists, human rights advocates, and opposing political figures.

The Working of Firewalls





If you have been using Internet on a regular basis or working in a large company and surf the Internet while you are at work, you must have surely come across the term firewall.
You might have also heard of people saying firewalls protect their computer from web attacks and hackers or certain website has been blocked by firewall in their work .place If you have ever wondered to know what exactly is this firewall and how it works, here we go. In this post I will try to explain How firewalls work in a layman terms.

How Firewalls Work?
Firewalls are basically a barrier between your computer (or a network) and the Internet (outside world). A firewall can be simply compared to a security guard who stands at the entrance of your house and filters the visitors coming to your place. He may allow some visitors to enter while denying others whom he suspects of being intruders. Similarly a firewall is a software program or a hardware device that filters the information (packets) coming through the Internet to your personal computer or a computer network.
The working of a Firewall Firewalls may decide to allow or block network traffic between devices based on the rules that are pre-configured or set by the firewall administrator. Most personal firewalls such as Windows firewall operate on a set of pre-configured rules that are most suitable under normal circumstances so that, the user need not worry much about configuring the firewall.
Personal firewalls are easy to install and use and hence preferred by end-users for use on their personal computers. However, large networks and companies prefer those firewalls that have plenty of options to configure so as to meet their customized needs. For example, a company may set up different firewall rules for FTP servers, Telnet servers and Web servers. In addition, the company can even control how the employees connect to the Internet by blocking access to certain websites or restricting the transfer of files to other networks. Thus, in addition to security, a firewall can give the company a tremendous control over how people use the network. Firewalls use one or more of the following methods to control the incoming and outgoing traffic in a network:

Packet Filtering: In this method, packets (small chunks of data) are analyzed against a set of filters. Packet filters has a set of rules that come with accept and deny actions which are pre-configured or can be configured manually by the firewall administrator. If the packet manages to make it through these filters then it is allowed to reach the destination; otherwise it is discarded.

Stateful Inspection: This is a newer method that doesnt analyze the contents of the packets. Instead, it compares certain key aspects of each packet to a database of trusted source. Both incoming and outgoing packets are compared against this database and if the comparison yields a reasonable match, then the packets are allowed to travel further. Otherwise they are discarded.



Firewall Configuration:
Firewalls can be configured by adding one or more filters based on several conditions as mentioned below:

--IP addresses: In any case, if an IP address outside the network is said to be unfavorable, then it is possible to set filter to block all the traffic to and from that IP address. For example, if a certain IP address is found to be making too many connections to a server, the administrator may decide to block traffic from this IP using the firewall.

--Domain names: Since it is difficult to remember the IP addresses, it is an easier and smarter way to configure the firewalls by adding filters based on domain names. By setting up a domain filter, a company may decide to block all access to certain domain names, or may provide access only to a list of selected domain names.

--Ports/Protocols: Every service running on a server is made available to the Internet using numbered ports, one for each service. In simple words, ports can be compared to virtual doors of the server through which services are made available.

--For example, if a server is running a Web (HTTP) service then it will be typically available on port 80. In order to avail this service, the client needs to connect to the server via port 80. Similarly, different services such as Telnet (Port 23), FTP (port 21) and SMTP (port 25) services may be running on the server.

--If the services are intended for the public, they are usually kept open. Otherwise they are blocked using the firewall so as to prevent intruders from using the open ports for making unauthorized connections.

--Specific words or phrases: A firewall can be configured to filter one or more specific words or phrases so that, both the incoming and outgoing packets are scanned for the words in the filter. For example, you may set up a firewall rule to filter any packet that contains an offensive term or a phrase that you may decide to block from entering or leaving your network.

Hardware vs. Software Firewall:
Hardware firewalls provide higher level of security and hence preferred for servers where security has the top most priority. The software firewalls on the other hand are less expensive and hence preferred in home computers and laptops.
Hardware firewalls usually come as an in-built unit of a router and provide maximum security as it filters each packet in the hardware level itself even before it manages to enter your computer.
A good example is the Linksys Cable/DSL router.

Why Firewall?
Firewalls provide security over a number of online threats such as Remote login, Trojan backdoors, Session hijacking, DOS & DDOS attacks, viruses, cookie stealing and many more. The effectiveness of the security depends on the way you configure the firewall and how you set up the filter rules.
However, major threats such as DOS and DDOS attacks may sometimes manage to bypass the firewalls and do the damage to the server. Even though firewall is not a complete answer to online threats, it can most effectively handle the attacks and provide security to the computer up to the maximum possible extent.
