  Agent handling - Wikipedia, the free encyclopedia
Agent handler is a generic term common to many intelligence organizations which can be applied to Case Officers, those who aspire to be Case officers, "controllers", contacts, couriers and other assorted trainees.
Agents are typically under the direction of an agent handler or controller.
In some forms of infiltration, the agent may be provided with a false identity, which CIA calls a cover or legend, that might aid in their access and operability in regards to the target.

 netsnmp_handler(3): basic theory goes something ... - Linux man page
Net-SNMP Agent handler and extensibility API - The basic theory goes something like this: In the past, with the original mib module api (which derived from the original CMU SNMP code) the underlying mib modules were passed very little information (only the truly most basic information about a request).
With the rewrite of the agent internals for the net-snmp 5.0 release, we introduce a modular calling scheme that allows agent modules to be written in a very flexible manner, and more importantly allows reuse of code in a decent way (and without the memory and speed overheads of OO languages like C++).
Functionally, the notion of what a handler does is the same as the older api: A handler is created and then registered with the main agent at a given OID in the OID tree and gets called any time a request is made that it should respond to.

 Observer | British 'agent handler' lifts lid on Nelson story
The man, known only as 'Geoff', is the first agent handler to break the official silence surrounding allegations that Britain has waged a 'dirty war' against IRA sympathisers.
Nelson was meant to save lives by passing details of planned 'hits' to his handlers, who were supposed to pass it on so the operation could be thwarted.
Nelson was unmasked as an army agent involved in murder in 1990 after John Stevens, then the Deputy Chief Constable of Cambridgeshire, investigated collusion between the security forces and the loyalist paramilitaries.

The handler resolves the hostname to an IP address and sends the command "mstream/arg1:arg1/arg2" to all agents, where "arg1" is the resolved hosts' IP address twice with a colon between (this simplifies argument parsing in the agent) and "arg2" is the duration in seconds.
The handler sends the command "mstream/arg1/arg2" to all agents, where "arg1" is the list of colon separated IP addresses, and "arg2" is the duration in seconds.
Even though the agent "in the wild" had two options for accepting DDoS commands, namely "stream" and "mstream" as in the published source, only the mstream command is used in the handler to agent protocol.

 CERT Incident Note IN-2000-05: mstream Distributed DoS
The handler can be controlled remotely by one or more intruders using a password-protected interactive login to a running handler.
The communications between intruder and handler, and the handler and agents, are configurable at compile time and have varied significantly from incident to incident.
The apparent intent for 'stream' is to cause the handler to instruct all known agents to launch a TCP ACK flood against a single target IP address for a specified duration.

Whereas the source port spoofing only works if the agent is running as a root privileged process, the author has added provisions for packet flooding using the UDP protocol and with the correct source address in the case the process is running as a simple user process.
A better means of detecting "Shaft" handlers and agents would be to use a program like "rid", which uses a more flexible configuration file mechanism to define ports, protocols, and payloads.

 Answers for the Reverse Challenge
The IP address of the handler is needed when replying to a status report query, or returning the output of an executed command.
Each time the agent is to send a packet to a handler, the packet is sent to each of these 10 IP addresses.
If the agent is performing a slow action, and a request to perform a different slow action arrives, the first action is terminated immediately, before starting the second.

creates a table handler given the netsnmp_table_registration_info object, inserts it into the request chain and then calls netsnmp_register_handler() to register the table into the agent.
By creating a table handler and injecting it into your calling chain, or by using the netsnmp_register_table() function to register your table, you get access to some pre-parsed information.
A netsnmp_table_registeration_info structure that is passed to the table handler should contain the asn index types for the table as well as the minimum and maximum column that should be used.

 Chimera - Details
Chimera is based on a very clean architecture, in which agents react to events and respond by posting further events, and where these events may be generated or posted locally or across a network.
An "agent", so far as Chimera is concerned, is a named software entity which reacts to events, generated both within itself and from elsewhere on a distributed network.
This closes the agent of the given Name (atom), as well as any links that have been set up to or from the agent, and is effectively the reverse action of agent_create/3 with or without automatic calls to agent_close/2 as needed.

Agent Commands ============== The handler communicates to agents using string based commands in the data portion of UDP packets.
Bugs in the source code for both handler and agent result in an increasing number of raw sockets and UDP sockets in the agent (three each are were witnessed on this agent), and an increasing number of open file handles and UDP sockets in the handler (hundreds were shown by Andrew Korty).
If a rootkit is in place (as it was on both handler and agent systems), you cannot trust the standard operating system commands to show you the running handler or agent, or their network connections.

Stacheldraht agents were originally found in binary form on a number of Solaris 2.x systems, which were identified as having been compromised by exploitation of buffer overrun bugs in the RPC services "statd", "cmsd" and "ttdbserverd".
The mass-instrusion phase is followed by the actual denial of service attack phase, in which these compromised systems which constitute the handlers and agents of the distributed attack network are used to wage massive denial of service attacks against one or more sites.
In addition to finding an active handler, the agent performs a test to see if the network on which the agent is running allows packets to exit with forged source addresses.

 Bug ID: 4176736 -Xdebug hangs in 1.2fcs-K
The class loader has thrown an exception (it does this as part of normal processing) so it must send an exception event to the event handler (but to do this it must get an event lock notification, which will never come because the event handler is waiting for the class loader lock).
The traces provided by licensees show this scenario with the event handler and main threads in a variety of states.
Proposed workaround: This problem is the result of an architectural flaw in sun.tools.debug: the back-end agent is written in Java and thus competes with the user program for resources.

 israelinsider: politics: Mossad officer vows to free Pollard, but jailed agent says handler wanted to kill him
Rafi Eitan, a legendary Israeli intelligence officer and the recruiter and handler of imprisoned spy Jonathan Pollard, said here yesterday if elected to a Knesset seat he would work for Pollard's release.
But when Pollard arrived at the embassy, he was received at first then expelled into the custody of FBI agents waiting outside.
Pollard's wife Esther told WND she was "stunned" by Eitan's recent statements about helping her husband, explaining she and attorney Larry Dub previously held a meeting in which Eitan said he would have killed Pollard if he had been present at the Israeli Embassy when Pollard sought sanctuary.

 Analysis of "stacheldraht"
For more information on trinoo and TFN, see: http://staff.washington.edu/dittrich/misc/trinoo.analysis http://staff.washington.edu/dittrich/misc/tfn.analysis In late June and early July of 1999, one or more groups were installing and testing trinoo networks and waging medium to large scale denial of service attacks employing networks of over 2000 compromised systems.
Once the agent has determined a list of potential handlers, it then starts at the beginning of the list of handlers and sends an ICMP ECHO_REPLY packet with an ID field containing the value 666 and data field containing the string "skillz".
Dirty works fine for me. I found three agents when I ran it "live."] The strings "skillz", "spoofworks", "sicken", "niggahbitch", and "ficken" -- all sent in ICMP data segments -- are not encrypted, so are visible in the data portion of ICMP ECHO_REPLY packets.

The prompt shows the number of agents that are believed to be active ("a!") and dead ("d!") at the time.
When each agent starts up, it attempts to read a master server configuration file to learn which handler(s) may control it.
There is also a code in the agent to perform an ID test, sending an ICMP_ECHOREPLY packet with an ID field value of 669, and the string "sicken\n" in the data field.
