    I agree that everyone has something to hide, just as everyone is a target of 'cyber' attacks. However, while I have not yet read the full bill and the linked article is a bit sparse on actual fact, sharing attack data would be tremendously helpful. If private companies are able to share STIX/IOC's (with information deemed private stripped out) that information would be very useful. While I worked for an Amazon sub, we couldn't even get attack data amoungst companies that were, essentially the same. Currently if you were to ask your biggest competitor to share data, you will get a 'No, thanks' at best. Most of this seems to be from lawyers/compliance people that seem to think sharing the data will make the sky fall. There are some private companies attempting to do this but the solutions are immature and not really ready for any sort of meaningful exchange. Facebook is doing their Intel sharing but it hasn't gotten off the ground yet.

    I would agree that the government is probably not the best clearing house for true threat data. Look at infraguard & cert, sure they send out useful data but it's usually late and if you want the really interesting bits, you need a clearance (which working at a private company is practically a non-starter). The security industry needs to figure this out for itself before the fed steps in and makes it the same black hole sharing data with them currently is.

    Sadly this is too true. A lot of the shops out there don't understand mitigating controls or 'we tweaked a configuration so we aren't vulnerable, despite what the banner says and here's output from us actually using the exploit....see not vulnerable'. That's one of the major issues I have with PCI, it's far to common for the auditors to not understand the context of the controls, let alone how the network is configured. I remember having to argue with an auditor about how umask worked and sudo.

    When we evaluate third party companies we request the most recent pentest report (depending on the data being shared) and most of what we get back is simply screenshots from some vuln scanner and clearly it says Apache so it must be vulnerable. I would love for the end customers to be more educated on what the deliverables should be for a pentest.

    Like defenders, pentesters generally need to find all the vulnerabilities (sadly many customers accept the first one which ends up being a scoping issue) and understand how to mitigate anything that was discovered/exploited. That requires an understanding of protocols, networking, applications, web frameworks, etc.. I have found that the best tend to have the capacity to think maliciously. IMO, that is a critical skill. I have seen far too many people that just don't understand why anyone would want to abuse a protocol, which makes them substandard pentesters.

    As for the original question, there are plenty of tools out there that can help you learn. Metasploitable, WebGoat, Kali, SamuraiWTF (disclosure, I am good friends with the lead for that), ZAP, Burp Suite (pro is great and super reasonable). If you have corporate funding, there are some decent trainings out there Offensive Security has their classes (and certs, I have heard mixed results). There is also SANS, which I have been increasing disappointed with but if you want a bunch of knowledge shoved in your head (at a pretty high dollar cost), they tend to do it. Also, some drift more towards network pentesting or application, personally, I think people should be versed in both (leveraging a remote code execution bug in a webserver is great unless you have no clue what to do within the OS).

    For cheaper options there are bunch of books that can teach you a ton of 'tips and tricks' around pentesting (web Hackers Handbook 2nd Edition is particularly good). Having a solid background as a sysadmin makes it much easier IMO (my background is similar), since you are most likely familiar with troubleshooting, networking, multiple OS's and what not.

  17. Re:posting the emails was illegal and unproductive on Republican Aide Tries to Hire Hackers · · Score: 1

    I myself am not a lawyer, but unless I am misunderstanding your statement, it looks like your interpretation of both doctor & patient and attorney & client privilege is a bit off.

    A doctor can decide to alert the police if he knows you are going to endanger yourself, or someone else. Usually this results in a person being committed for some period of time. If you tell your shrink that you had harmed someone in the past, they aren't bound to tell the police about it. In fact, I don't think they can tell even if they wanted to. A patient can decide to allow a doctor, but the doctor is only released after a patient dies (without consent).

    An example (from wikipedia: http://en.wikipedia.org/wiki/Physician-patient_pri vilege):

    For example, let us say a below-age of consent girl came to a doctor with a sexually transmitted disease. The doctor is usually required to obtain a list of the patient's sexual contacts to inform them that they need treatment. This is an important health concern. However, it is likely that the girl might reveal her partners were older, and this could result in a fear that they would be charged with a crime such as statutory rape. In some jurisdictions, the doctor cannot be forced to reveal the information revealed by his patient to anyone except the appropriate health authorities, and they too are required to keep that information confidential. If, in the case, the police become aware of such information, they are not allowed to use it in court as proof of the sexual conduct.

    As for Lawyers, they are bound by not only privilege, but by ethic constraints as well. There are some interesting distinctions between Washington state law (which only allows privilege protection for the extent that a conversation contains or reveals client communications). Where California law protects all communications between a client and attorney (again wiki: http://en.wikipedia.org/wiki/Attorney-client_privi lege). At the same time, an attorney cannot let you testify that you are innocent of something, if you have divulged your guilt to him. This explains why some lawyers don't want to know the exact details, since not knowing leaves more options open. At the same time, if a lawyer steps over the bounds and gets caught they can be disbarred or worse.

    There is also a privilege for accountant-client and for clergy-parishioner.

    Though I have only found one http://www.eff.org/news/archives/2006_11.php#00501 7article that is directly on point (after a quick google search). The article specifically mentions a 2006 reversal by the California Supreme Court, (original case Barrett v. Rosenthal http://www.eff.org/legal/cases/Barrett_v_Rosenthal /ruling.pdf) which upholds that blogs, websites, listservs, etc. are protected under the Communications Decency Act (CDA 1996) Section 230. This section explicitly states that "[n]o provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider."

    Other relevant portions of the article:

    "The issue raised in Barrett v. Rosenthal was whether Section 230's protection applies to individuals who frequently use the internet to pass on information obtained elsewhere, whether by forwarding an email written by someone else or, as was the case in Barrett, posting an email from someone else to a newsgroup."

    The CDA basically covers anyone from being sued, prosecuted {in my non-legal opinion) for posting forwarding emails from other sources. It is unclear from the article, and I don't have time to reread the CDA at the moment, if this also covers emails that include the 'privacy' footer. However, email is a public method of passing data around, there isn't any expectation of privacy in this form of communication. Finding and ferreting out a private email, either from a mail server, or while it is traveling through a network, isn't a very tough thing to do. You just have to know where to look.

People would notice someone walking around the office taking pictures of sensitive data. Have you ever tried to photograph a piece of paper? It's not like in the movies where you just lay it flat and start snapping pictures. If you are using a regular digital camera, you have to get the document in focus, if you are trying to get the whole document you have to make sure that all of it can be read from the shot (also make sure that the flash doesn't go off - nothing like attracting attention). If you are taking the picture in sections, you need to make sure that you get the whole thing with enough overlap that you can reasemble the document.

So it is doubtful that the rest of the world and researchers in the states, haven't closed that gap significantly. But the fact that it took researchers outside of Ft. Meade two decades to discover that the 'tweaks' made to DES by the NSA, actually made it stronger to an attack that didn't even exist (again, to anyone outside of Ft. Meade) means that the NSA had to be ahead of the curve (about 20 years ahead).

So what I do is use the Cantenna (yes, see lazy comment above) and point it in the direction that I want it to. If the network is encrypted I use the wireless card that came in my original airport base station (an Orinoco silver card), since the Airport Extreme one has closed source drivers (that have not been reversed yet), too sniff and collect packets. Kismac is an excellent wireless tool for the Mac. It supports several different cards and supports Wordlist, Brute Force, and Scheduling Attacks (which I find usually get me into most networks). The Dlink Bridge has a pretty simple web interface that allows you to set it up to join a specific network. It also supports scanning for networks, though I find that it doesn't seem to pick up everything that maybe out there. I set this up on top of those ridiculously tall TV cabinets and I can kick back on the bed without those pesky ethernet cables. This can also be useful if you have a large house (or a small house with interferance) to connect up in rooms that were previously spotty.

    The pre-made Can Antenna can be purchased for $49.99 (via CompUSA or the web), the Dlink Bridge is $109 from Fry's, Airport Express for $199 (various vendors).

    I have found that some hotels have pretty crappy coverage in the outer rooms, so they let you 'barrow' (for a deposit) one of the Dlink Bridges, preconfigured to join their networks.

Also the San Diego and San Fransico airports have approaches over water, so a wacko can sit in a boat and try this. Even the military base in Las Vegas has a flight path that puts them over the vast majority of the town, and we house one of the larger fighter wings (at least I think we do).
