Zitmo's new variant targeting Android and Blackberry
As per the sources, Zitmo is not a new thing, it has been in the market for quite long ~ 2 years but this time Blackberry platform has been targetted which seems to be a new thing.
They have got new files of Zitmo, 4 have been found for Blackberry( 3.cod files and 1 .jar files) and 1 for Android (.apk). But this ZeuS-in-the-Mobile for Android has been modified and now looks like a ‘classic’ ZitMo with same commands and logic.
These samples have been found to target users from Germany, Spain and Italy. For android, there has been an app which pretended to be "certificate update" or "security" apps. As the user clicks on the same, it pops up some Text in German language.
More details can be found here .

Replacements for Linux Commands : Part 2
So moving further with our FIRST PART , lets move onwards.
Iwconfig
Deprecated iwconfig commands |
Replacement |
|---|---|
| iwconfig . Displays basic details about wireless interfaces, such as supported protocols (802.11a/b/g/n), Extended Service Set ID (ESSID), mode, and access point. To view these details about a particular interface, use iwconfig [interface] where the interface is the device name, such as wlan0. |
iw dev [interface] link |
| iwconfig [interface] ap [address] . Forces the wireless adapter to register with the access point given by the [address], if possible. This address is the cell identity of the access point (as reported by wireless scanning) which may be different from its MAC address. |
Not apparent |
| iwconfig commit . Some wireless adapters may not apply changes immediately (they may wait to aggregate the changes, or apply them only when the card is brought up via ifconfig). This command (when available) forces the adapter to immediately apply all pending changes. |
Not apparent |
| iwconfig [interface] essid [name] . Connects to the WLAN with the ESSID [name] provided. With some wireless adapters, you can disable the ESSID checking (ESSID promiscuous) with off or any (and on to re-enable it). |
iw [interface] connect [name] |
| iwconfig [interface] frag [num] . Sets the maximum fragment size which is always lower than the maximum packet size. This parameter may also control Frame Bursting available on some wireless adapters (the ability to send multiple IP packets together). This mechanism would be enabled if the fragment size is larger than the maximum packet size. Other valid frag parameters to auto, on, and off. |
Not apparent |
| iwconfig [interface] [freq | channel] . Sets the operating frequency or channel on the wireless device. A value below 1000 indicates a channel number, a value greater than 1000 is a frequency in Hz. You can append the suffix k, M or G to the value (for example, “2.46G” for 2.46 GHz frequency). You may also use off or auto to let the adapter pick up the best channel (when supported). |
iw dev [interface] set freq [freq] [HT20|HT40+|HT40-] . iw dev [interface] set channel [chan] [HT20|HT40+|HT40-] |
| iwconfig [interface] key [key] [mode] [on | off] . To set the current encryption [key], just enter the key in hex digits as XXXX-XXXX-XXXX-XXXX or XXXXXXXX. You can also enter the key as an ASCII string by using the s: prefix. On and off re=enable and disable encryption. The security mode may be open or restricted, and its meaning depends on the card used. With most cards, in open mode no authentication is used and the card may also accept non-encrypted sessions, whereas in restricted mode only encrypted sessions are accepted and the card will use authentication if available. |
iw [interface] connect [name] keys [key] (for WEP) . To connect to an AP with WPA or WPA2 encryption, you must use wpa_supplicant. |
| iwconfig [interface] mode [mode] . Sets the operating mode of the wireless device. The [mode] can be Ad-Hoc, Auto, Managed, Master, Monitor, Repeater, or Secondary. . Ad-Hoc: the network is composed of only one cell and without an access point. Managed: the wireless node connects to a network composed of many access points, with roaming. Master: the wireless node is the synchronization master, or it acts as an access point. Monitor: the wireless node is not associated with any cell and passively monitors all packets on the frequency. Repeater: the wireless node forwards packets between other wireless nodes. Secondary: the wireless node acts as a backup master/repeater. |
Not apparent |
| iwconfig [interface] modu [modulation] . Forces the wireless adapter to use a specific set of modulations. Modern adapters support various modulations, such as 802.11b or 802.11g. The list of available modulations depends on the adapter/driver and can be displayed using iwlist modulation. Some options are 11g, CCK OFDMa, and auto. |
Not apparent |
| iwconfig [interface] nick [name] . Sets the nick name (or station name). |
Not apparent |
| iwconfig [interface] nwid [name] . Sets the Network ID for the WLAN. This parameter is only used for pre-802.11 hardware as the 802.11 protocol uses the ESSID and access point address for this function. With some wireless adapters, you can disable the Network ID checking (NWID promiscuous) with off (and on to re-enable it). |
Not apparent |
| iwconfig [interface] power [option] iwconfig [interface] power min | max [secondsu | secondsm] iwconfig [interface] power mode [mode] iwconfig [interface] power on | off . Configures the power management scheme and mode. Valid [options] are: period [value] (sets the period between wake ups), timeout [value] (sets the timeout before going back to sleep), saving [value] (sets the generic level of power saving). The min and max modifiers are in seconds by default, but append the suffices m or u to specify values in milliseconds or microseconds. Valid [mode] options are: all (receive all packets), unicast (receive unicast packets only, discard multicast and broadcast) and multicast (receive multicast and broadcast only, discard unicast packets). On and off re-enable or disable power management. |
Not apparent; some power commands are: . iw dev [interface] set power_save on . iw dev [interface] get power_save |
| iwconfig [interface] rate/bit [rate] . Sets the bit rate in bits per second for cards supporting multiple bit rates. The bit-rate is the speed at which bits are transmitted over the medium, the user speed of the link is lower due to medium sharing and various overhead.Suffixes k, M or G can be added to the numeric [rate] (decimal multiplier : 10^3, 10^6 and 10^9 b/s), or add ‘0‘ for enough. The [rate] can also be auto to select automatic bit-rate mode (fallback to lower rate on noisy channels), or fixed to revert back to fixed setting. If you specify a bit-rate numeric value and append auto, the driver will use all bit-rates lower and equal than this value. |
iw [interface] set bitrates legacy-2.4 12 18 24 |
| iwconfig [interface] retry [option] [value] . To set the maximum number of retries (MAC retransmissions), enter limit [value]. To set the maximum length of time the MAC should retry, enter lifetime [value]. By default, this value is in seconds; append the suffices m or u to specify values in milliseconds or microseconds. You can also add the short, long, min and max modifiers. |
Not apparent |
| iwconfig [interface] rts [threshold] . Sets the size of the smallest packet for which the node sends RTS; a value equal to the maximum packet size disables the mechanism. You may also set the threshold parameter to auto, fixed or off. |
Not apparent |
| iwconfig [interface] sens [threshold] . Sets the sensitivity threshold (defines how sensitive the wireless adapter is to poor operating conditions such as low signal, signal interference, etc). Modern adapter designs seem to control these thresholds automatically. |
Not apparent |
| iwconfig [interface] txpower [value] . For adapters supporting multiple transmit powers, this sets the transmit power in dBm. If W is the power in Watt, the power in dBm is P = 30 + 10.log(W). If the [value] is postfixed by mW, it will be automatically converted to dBm. In addition, on and off enable and disable the radio, and auto and fixed enable and disable power control (if those features are available). |
iw dev [interface] set txpower [auto | fixed | |limit] [tx power in mBm] . iw phy [phyname] set txpower [auto | fixed | limit] [tx power in mBm] |
| iwconfig –help . Displays the iwconfig help message. |

Nameif
Deprecated nameif commands |
Replacement |
|---|---|
| nameif [name] [mac_address] . If no name and MAC address are provided, it attempts to read addresses from /etc/mactab. Each line of mactab should contain an interface name and MAC address (or comments starting with #). |

Replacements for Linux Commands : Part 1
From so long we have been using many of the Linux commands, which can however can be replaced with some optional commands, which sounds damn easy and small as compared to old ones. Specifically, the commands which can be ignored while using Linux networking are: arp, ifconfig, iptunnel, iwconfig,nameif, netstat, and route. These programs (except iwconfig) are included in the net-tools package that has been unmaintained for years. The functionality provided by several of these utilities has been reproduced and improved in the new iproute2 suite, primarily by using its new ip command. The iproute2 software code and documentation are available from the Linux Foundation.
Now let’s take a closer look at these commands and their replacements.
This article will not focus on iproute2 or the ip command in detail; instead it will simply give one-to-one mappings between the deprecated commands and their new counterparts. For replacement commands that are listed as ‘not apparent’, please contact me if you know otherwise.

This article will not focus on iproute2 or the ip command in detail; instead it will simply give one-to-one mappings between the deprecated commands and their new counterparts. For replacement commands that are listed as ‘not apparent’, please contact me if you know otherwise.
.
Some ip neighbor examples are as follows:
# ip n del 10.1.2.3 dev eth0
Invalidates the ARP cache entry for host 10.1.2.3 on device eth0.
# ip neighbor show dev eth0
Shows the ARP cache for interface eth0.
# ip n add 10.1.2.3 lladdr 1:2:3:4:5:6 dev eth0 nud perm
Adds a “permanent” ARP cache entry for host 10.1.2.3 device eth0. The Neighbor Unreachability Detection (nud) state can be one of the following:
.
Some examples illustrating the ip command are as follows; using the table above you should be able to figure out what they do.
# ip link show dev eth0
# ip a add 10.11.12.13/8 dev eth0
# ip link set dev eth0 up
# ip link set dev eth0 mtu 1500
# ip link set dev eth0 address 00:70:b7:d6:cd:ef
.
The syntax between iptunnel and ip tunnel is very similar as these examples show.
# [iptunnel | ip tunnel] add ipip-tunl1 mode ipip remote 83.240.67.86 (ipip-tunl1 is the name of the tunnel, 83.240.67.86 is the IP address of the remote endpoint).
# [iptunnel | ip tunnel] add ipi-tunl2 mode ipip remote 104.137.4.160 local 104.137.4.150 ttl 1
# [iptunnel | ip tunnel] add gre-tunl1 mode gre remote 192.168.22.17 local 192.168.10.21 ttl 255

.
Now let’s take a closer look at these deprecated commands and their replacements.
This article will not focus on iproute2 or the ip command in detail; instead it will simply give one-to-one mappings between the deprecated commands and their new counterparts. For replacement commands that are listed as ‘not apparent’, please contact me if you know otherwise.
Arp
Deprecated arp commands |
Replacement |
|---|---|
| arp -a [host] or –all [host] . Shows the entries of the specified host name or IP address. If the [host] parameter is not used, all entries will be displayed. |
ip n (or ip neighbor), or ip n show |
| arp -d [ip_addr] or –delete [ip_addr] . Removes the ARP cache entry for the specified host. |
ip n del [ip_addr] (this “invalidates” neighbor entries) . ip n f [ip_addr] (or ip n flush [ip_addr]) |
| arp -D or –use-device . Uses the hardware address associated with the specified interface. |
Not apparent |
| arp -e . Shows the entries in default (Linux) style. |
Not apparent |
| arp -f [filename] or –file [filename] . Similar to the -s option, only this time the address info is taken from the file that [filename] set up. If no [filename] is specified, /etc/ethers is used as default. |
Not apparent |
| arp -H or –hw-type [type] or -t [type] . When setting or reading the ARP cache, this optional parameter tells arp which class of entries it should check for. The default value of this parameter is ether (i.e. hardware code 0×01 for IEEE 802.3 10Mbps Ethernet). |
Not apparent |
| arp -i [int] or –device [int] . Selects an interface. When dumping the ARP cache only entries matching the specified interface will be printed. For example, arp -i eth0 -s 10.21.31.41 A321.ABCF.321A creates a static ARP entry associating IP address 10.21.31.41 with MAC address A321.ABCF.321A on eth0. |
ip n [add | chg | del | repl] dev [name] |
| arp -n or –numeric . Shows IP addresses instead of trying to determine domain names. |
Not apparent |
| arp -s [ip_addr] [hw_addr] or –set [ip_addr] . Manually creates a static ARP address mapping entry for host [ip_addr] with the hardware address set to [hw_addr]. |
ip n add [ip_addr] lladdr [mac_address] dev [device] nud [nud_state] (see example below) |
| arp -v . Uses verbose mode to provide more details. |
ip -s n (or ip -stats n) |
Some ip neighbor examples are as follows:
# ip n del 10.1.2.3 dev eth0
Invalidates the ARP cache entry for host 10.1.2.3 on device eth0.
# ip neighbor show dev eth0
Shows the ARP cache for interface eth0.
# ip n add 10.1.2.3 lladdr 1:2:3:4:5:6 dev eth0 nud perm
Adds a “permanent” ARP cache entry for host 10.1.2.3 device eth0. The Neighbor Unreachability Detection (nud) state can be one of the following:
- noarp – entry is valid. No attempts to validate this entry will be made but it can be removed when its lifetime expires.
- permanent – entry is valid forever and can be only be removed administratively.
- reachable – entry is valid until the reachability timeout expires.
- stale – entry is valid but suspicious.
Ifconfig
Deprecated ifconfig commands
|
Replacement |
|---|---|
| ifconfig . Displays details on all network interfaces. |
ip a (or ip addr) |

ip mr iif [name] or ip mroute iif [name], where [name] is the interface on which multicast packets are received. |
| ifconfig [interface] arp or -arp . Enables or disables the use of the ARP protocol on this [interface]. |
ip link set arp on or arp off |
| ifconfig [interface] broadcast [address] . Specifies the address to use to use for broadcast transmissions. By default, the broadcast address for a subnet is the IP address with all ones in the host portion of the subnet address (i.e., a.b.c.255 for a /24 subnet). |

Not apparent; possibly ethtool. |
| ifconfig [interface] media [type] . Sets physical port or medium type. Examples of [type] are 10baseT, 10base2, and AUI. A [type] value of auto will tell the interface driver to automatically determine the media type (driver support for this command varies). |
Not apparent; possibly ethtool. |
| ifconfig [interface] mtu [n] . Sets the Maximum Transfer Unit (MTU) of an interface to [n]. |
ip link set dev [interface] mtu [n] |

ip link set dev [interface] multicast on or off |
| ifconfig [interface] netmask [mask_address] . Sets the subnet mask (not the IP address) for this [interface]. This value defaults to the standard Class A, B, or C subnet masks (based on the interface IP address) but can be changed with this command. |
Not apparent |

ip link set dev [interface] promisc on or off |
| ifconfig [interface] txquelen [n] . Sets the transmit queue length on the [interface]. Smaller values are recommended for connections with high latency (i.e., dial-up modems, ISDN, etc). |
ip link set dev [interface] txqueuelen [n] or txqlen [n] |
| ifconfig [interface] tunnel [address] . Creates a Simple Internet Transition (IPv6-in-IPv4) device which tunnels to the IPv4 [address] provided. |
ip tunnel mode sit (other possible modes are ipip and gre). |
| ifconfig [interface] up . Activates (enables) the [interface] specified. |
ip link set [interface] up |
Some examples illustrating the ip command are as follows; using the table above you should be able to figure out what they do.
# ip link show dev eth0
# ip a add 10.11.12.13/8 dev eth0
# ip link set dev eth0 up
# ip link set dev eth0 mtu 1500
# ip link set dev eth0 address 00:70:b7:d6:cd:ef

| iptunnel add [name] [mode {ipip | gre | sit} ] remote [remote_addr] local [local_addr] | ip tunnel add [name] [mode {ipip | gre | sit | isatap | ip6in6 | ipip6 | any }] remote [remote_addr] local [local_addr] |
| iptunnel -V or –version | not apparent |
The syntax between iptunnel and ip tunnel is very similar as these examples show.
# [iptunnel | ip tunnel] add ipip-tunl1 mode ipip remote 83.240.67.86 (ipip-tunl1 is the name of the tunnel, 83.240.67.86 is the IP address of the remote endpoint).
# [iptunnel | ip tunnel] add ipi-tunl2 mode ipip remote 104.137.4.160 local 104.137.4.150 ttl 1
# [iptunnel | ip tunnel] add gre-tunl1 mode gre remote 192.168.22.17 local 192.168.10.21 ttl 255

9 Suggestions which Apple gave to Samsung
Saturday, The Verge reported that Apple, in their usual arrogant way, felt they needed to tell Samsung how to design their devices. The list is quite humorous and completely outrageous.
Apple has told Samsung that, in order not to infringe on their design, Samsung should create a design with:
- Display screens that aren't centered on the front face and have substantial lateral borders.
- No front bezel at all.
- Non-horizontal speaker slots.
- Thick frames rather than a thin rim around the front surface.
- Profiles that aren't thin.
- Front surface that isn't black.
- Overall shape that isn't rectangular, or doesn't have rounded corner.
- Front surfaces with substantial adornment.
- Cluttered appearance.
Instead of improving their work, they are suggesting Samsung people. LOL. :D

World's First Android 4.0 Launched from China Market : Ice Cream Sandwich Tablet
There is no shortage of cheap Android tablets from Chinese manufacturers that can be found for under $200 online, most of which are running an older version of Android and don’t have Google’s blessing (meaning no Google services and Market). MIPS Technologies and Ingenic Semiconductor announced today availability of the world’s first Ice Cream Sandwich, Android 4.0-powered tablet, and it just so happens to a $99 budget-friendly tab with decent specs.
The tablet will pack in a 1GHz MIPS-based ‘XBurst” CPU, 7-inch capacitive touchscreen, microSD, HDMI 1.3, WiFi 802.11 b/g/n, USB 2.0, 2-megapixel main cam, front-facing cam, and bluetooth. Ainovo, the company offering up the tablet to the Chinese market, is promising 30 hours standby and 8 hours video playback for battery.
The Novo7 will become available to the US market (likely with different branding) through other companies including OMG Electronics Ltd. and Leader International Inc. at a later date. There will also be 8 and 9-inch variants released in the future, mostly likely depending on the success of the 7-inch model. You might have to pay a little more than the US $99 price tag to get it shipped from a Chinese supplier before it lands stateside, but it will probably be your first chance to get your hands on an ICS tablet if you do.
