http://www.washtimes.com/national/20021104-81830128.htm Officials attempt to get inside cells of al Qaeda in U.S. By Richard Sale UNITED PRESS INTERNATIONAL Local and federal law-enforcement agencies are attempting to infiltrate al Qaeda sleeper cells operating in the United States and are using disinformation campaigns to expose and neutralize the terror groups that continue to communicate with one another, U.S. intelligence officials say. FBI officials say recent electronic intercepts of communications between some al Qaeda groups show that they are "talking to each other." "The cells are up and active," an FBI official said of the groups believed to be embedded in most U.S. cities with sizable Islamic communities, such as New York, Detroit and Los Angeles. In a review of ongoing U.S. operations, United Press International was briefed on the al Qaeda investigations by several current and former intelligence officers, all of whom asked not to be identified by name. Former CIA and Defense Intelligence Agency officials say the terrorists choose run-down neighborhoods because "in a place like that, you are invisible. People don't care about you; they don't want to look at you and don't look at you," as one put it. A former senior U.S. intelligence official explained: "The members of cells don't think of themselves as raiding parties but as the front end of an invasion." "If they can attack, blow things up and disrupt society, they believe there will be mass defections to Islam and society will collapse. They can then set up an Islamic state." The cells, these sources said, are made up of U.S.-born Muslims and immigrants from Pakistan, Saudi Arabia and the Persian Gulf states, and number in the thousands. Most are thought to have entered the country some time ago and are deeply entrenched in their communities. To root them out, the FBI has been busy developing a network of informers in Muslim neighborhoods, including nightclub owners, waiters and merchants, a federal law-enforcement official said. Intelligence is the chief tool in the war on terror, a senior former Pentagon intelligence official said. "Intelligence is really just a giant research operation where you rely on huge archival files," he said. "It's the most effective weapon you've got." The next and best weapon in the war against the cells is infiltration. A longtime covert operations specialist said law enforcement is using agents who are Arabs and fluent in Arabic, who then look for ways to get inside the community where the cell members worship. Their next goal is "to find out about the social structure: Where do they worship, where do they entertain, what do they talk about?" he said. If it is known where they socialize and there is probable cause, local police might be able to place eavesdropping devices on the premises, he said. The goal is to identify and eliminate leaders, a former CIA official said. As the FBI and other law-enforcement agencies gain knowledge, any rivalries among group members can be exploited, using disinformation to convince some cell members that others are informers or traitors. One FBI official explained that the purpose is to "disrupt" hostile organizations, and that FBI tactics go back to 1956, when the FBI established its Cointelpro (counterintelligence program.) This official said the program pitted one group or even members of a single group against another "like gladiators in ancient Rome." The program has been used successfully against such groups as the Black Panthers and the Ku Klux Klan, he said

RE: What email encryption is actually in use?
by Tyler Durden 04 Nov '02

Peter Trei wrote... "Durden's question was whether a snooper on an IPSEC VPN can tell (for example) an encrypted email packet from an encrypted HTTP request. The answer is no. All Eve can tell is the FW1 sent FW2 a packet of a certain size. The protocol of the encapsulated IP packet, it's true source behind FW1, it's true destination behind FW2, and the true destination port are all hidden." Yes, this was indeed the gist of my question. I was aware that there are actually hard and soft switches that are aware all the way up to the application layer, apparently (I also know that some softswiches have actually been deployed in RBOC/Baby Bell territory.) But from your previous email, you indicated that the secure IPSEC tunnel is created by taking the packets, encrypting S/A, D/A, payload and protocol fields (ie, pretty much everything) and then dumping them into the payload of another packet, and setting the Protocol field of the parent-packet to "IPSEC". All that is now visible are the firewall addresses. That's a lot, methinks! In other words, there's practically a bright red flag sticking up saying "I'm encrypted! Look over here!"...it's child's play (well, if you consider making an ASIC child's play!) to then look at the S/A and D/a to see if they are interesting. If they belong to the IP spaces of two large companies, for instance, then look elsewhere (though I hear rumors that the NSAs of the world are branching out into industrial eavesdropping for their parent companies, ehr, for their parent countries). If a secure VPN tunnel forms between al-Jazeera's firewall and, say, some ISP near Atlantic Avenue in Brooklyn (heavy Arab community), then all sorts of spyglasses could pop up. Thus, I suspect a lot can be gleaned (and is) from communiques without actually de-encrypting...the philosohpy probably is, "why violate civil rights unless we really, really have to? Extract as much as we can without actually de-encrypting, and if the probably of something being "interesting" is high enough, then we'll send it downstairs to be opened" (and even then, determining how hard it is to open the communique might also be of interest...is it legal to open somebody else's email but not read it?) Here's a little quote for ya, since it seems to be the in-thing to do... "The revolution is right where we want it: out of our control."

The whole plaintext IP packet, from start to finish, including headers and checksum, gets treated as data, and encrypted. The encrypted packet is the data for a new packet, which goes from one firewall to another (and has only the firewall IP addresses exposed). The packets visible on the outside only tell Eve that firewall A sent firewall B an IPSEC packet of a certain size, with a particular Security Association. (ie, the protocol field says 'this is an IPSEC packet'). A single SA can be used for many, many, internal connections. Check the IPSEC RFCs for more info. Peter Trei
