US charges 60 in connection with the Zeus Trojan Posted: 30 Sep 2010 09:00 AM PDT U.S. authorities have charged more than 60 people in connection with the money-stealing Zeus Trojan program, according to the U.S. Department of Justice.

Microsoft's Security Essentials running on 31 million PCs Posted: 30 Sep 2010 09:00 AM PDT Microsoft's free antivirus software, Security Essentials, has been installed on 31 million PCs in its first year, the company has announced.

E-discovery moves in-house Posted: 30 Sep 2010 09:00 AM PDT When Jonathan Chow, chief information security officer at NBC Universal, found his department's services in increasing demand, that wasn't necessarily a good thing.

MIT system helps companies recover from network intrusion Posted: 30 Sep 2010 09:00 AM PDT MIT Computer Science and Artificial Intelligence Laboratory researchers will next week detail a system they say will make it easier for companies to recover from security intrusions.

ZeuS trojan bank-theft scheme extends to the U.S. Posted: 30 Sep 2010 09:00 AM PDT More than 60 people will be charged in the U.S. with using the Zeus trojan to steal millions of dollars from U.S. banks as part of a scheme that resulted in similar charges in the U.K. earlier this week.

Subnet masking Posted: 30 Sep 2010 06:38 AM PDT Subnetting an IP Network is done primarily for better utilization of available IP address space, and routing purpose. Other reasons include better organization, use of different physical media (such as Ethernet, WAN, etc.),  and securing network resources. A subnet mask enables you to identify the network and node parts of the address. The network bits are represented by the 1s in the mask, and the node bits are represented by the 0s. A logical AND operation between the IP address and the subnet mask provides the Network Address. For example, using our test IP address and the default Class C subnet mask, we get: 192.189.210.078: 1100 0000.1011 1101.1101 0010.0100 1110 Class C IP Address 255.255.255.000: 1111 1111.1111 1111.1111 1111.0000 0000 Default Class C subnet mask  192.189.210.0         1100 0000 1011 1101 1101 0010 0000 0000 As can be seen above, by using and AND operator, we can compute the network portion of an IP address.  The network portion for the IP address given in the above example is 192.189.210.0, and the host portion of the IP address is 078. Given below is a table that provides binary equivalent of decimal values.  For binary conversion, take first octet of a given IP address (in dotted decimal form), and lookup the binary value. Then take the second octet and lookup the binary value, and so on.

Explanation: IP addresses are written using decimal numbers separated by decimal points. This is called dotted decimal notation of expressing IP addresses. The different classes of IP addresses is as below: Class Format  Leading Bit  pattern Network address Range    Maximum  networks Maximum hosts      A N.H.H.H  0  0-126  127  16,777,214 B N.N.H.H     10  128-191  16,384  65,534 C N.N.N.H  110  192-223  2,097,152  254 Network address of all zeros means "This network or segment". Network address of all 1s means " all networks", same as hexadecimal of all Fs. Network number 127 is reserved for loopback tests. Host (Node) address of all zeros mean "This Host (Node)". Host (Node) address of all 1s mean "all Hosts (Nodes) " on the specified network.

IP Addressing Posted: 30 Sep 2010 06:18 AM PDT An IP address is a unique logical identifier for a node or host connection on an IP network. An IP address is a 32 bit binary number, and represented as 4 decimal values of 8 bits each. The decimal values range from 0 to 255. This is known as "dotted decimal" notation. Example: 192.189.210.078 It is sometimes useful to view the values in their binary form. 192     .189     .210     .078 11000000.10111101.11010010.1001110 Every IP address consists of network identifier and node identifier. The IP network is divided based on Class of network. The class of network is determined by the leading bits of the IP address as shown below. Address Classes There are 5 different address classes. You can determine which class any IP address is in by examining the first 4 bits of the IP address. Class A addresses begin with 0xxx, or 1 to 126 decimal. Class B addresses begin with 10xx, or 128 to 191 decimal. Class C addresses begin with 110x, or 192 to 223 decimal. Class D addresses begin with 1110, or 224 to 239 decimal. Class E addresses begin with 1111, or 240 to 254 decimal. Addresses beginning with 01111111, or 127 decimal, are reserved for loopback and for internal testing on a local machine. Class D addresses are reserved for multicasting. Class E addresses are reserved for future use. They should not be used for host addresses. Now we can see how the Class determines, by default, which part of the IP address belongs to the network (N) and which part belongs to the Host/node (H). Class A: NNNNNNNN.HHHHHHHH.HHHHHHHH.HHHHHHHH Class B: NNNNNNNN.NNNNNNNN.HHHHHHHH.HHHHHHHH Class C: NNNNNNNN.NNNNNNNN.NNNNNNNN.HHHHHHHH In the example, 192.189.210.078 is a Class C address so by default the Network part of the address (also known as the Network Address) is defined by the first three octets (192.189.210.XXX) and the node part is defined by the last one octets (XXX.XXX.XXX.078). In order to specify the network address for a given IP address, the node section is set to all "0"s. In our example, 192.189.210.0 specifies the network address for 192.189.210.078. When the node section is set to all "1"s, it specifies a broadcast that is sent to all hosts on the network. 192.189.210.255 specifies the broadcast address. Private Subnets There are three IP network addresses reserved for private networks. The addresses are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. They can be used by anyone setting up internal IP networks, such as an intranet. Internet routers never forward the private addresses over the public Internet.

11 Eastern Europeans charged in UK Zeus bust Posted: 30 Sep 2010 09:00 AM PDT They worked as Web designers, supermarket workers, day laborers, some were unemployed. But U.K. police say that the group of Eastern Europeans,picked up in early morning raids Tuesday also made millions by operating a network of bank-robbing Trojan horse programs.
