  • Can a malicious hacker share Linux distributions which trust bad root certificates?

    - by iamrohitbanga
    Suppose a hacker launches a new Linux distro with firefox provided with it. Now a browser contains the certificates of the root certification authorities of PKI. Because firefox is a free browser anyone can package it with fake root certificates. Thus a fake root certificate would contain a the certification authority that is not actually certified. Can this be used to authenticate some websites. How? Many existing linux distros are mirrored by people. They can easily package software containing certificates that can lead to such attacks. Is the above possible? Has such an attack taken place before?

  • How secure are third party Ubuntu (APT) repository mirrors

    - by bakytn
    Hello! We have locally an Ubuntu mirrors to save a lot of traffic (our external traffic is not free) So whenever I apt-get install "program" it gets from that repository. the question is...basically they can substitute any package with their own? So it's 100% on my own risk and I can be hacked easily on any apt-get upgrade or a-g install or a-g dist-upgrade? for example the very basic ones like "telnet" or any other.

  • fail2ban and denyhosts constantly ban me on Ubuntu

    - by Trey Parkman
    I just got an Ubuntu instance on Linode. To secure the SSH on it, I installed fail2ban (using apt-get), but then had a problem: fail2ban kept banning my IP (for limited durations, thankfully) even though I was entering the correct password. So I removed fail2ban and installed denyhosts instead. Same problem, but more severe: It seems like every time I SSH in, my IP gets banned. I remove it from /etc/hosts.deny, restart denyhosts and log in again, and my IP gets banned again. The only explanation I can think of is that I've been SSH-ing in as root (yes, yes, I know); maybe something is set somewhere that blocks anyone who SSH-es in as root, even if they log in successfully? This seems bizarre to me. Any ideas? (Whitelisting my IP is a temporary fix. I don't want to only be able to log on from one IP.)

  • Start multiple Firefoxes; Xephyr rootless mode

    - by Vi
    How to have multiple independent instances of Mozilla Firefox 3.5 on the same X server, but started from different user accounts (consequently, different profiles)? Limited success was only with Xephyr :1, DISPLAY=:1 /usr/local/bin/firefox, but Xephyr has no Cygwin/X's "rootless" mode so it not comfortable. The idea is to have one Firefox instance for various "Serious Business" things and the other for regular browsing with dozens of add-ons securely isolated. /* Requested tags: xephyr rootless */

  • Where are the Microsoft downloaded app compat updates stored?

    - by Ian Boyd
    Where are the Microsoft application compatibility update settings stored on a Windows XP, Windows Vista, and Windows 7 computer? Microsoft periodically release application compatibility updates (e.g. KB929427), where they list the shims that should be applied to a program in order to workaround known bugs in the software. Where are these app compat flags stored, and how can i see what shims are being applied? i have a feeling that a recent app compat update included a flag to force a particular piece of software, that we use, to require administrator. Because the task is scheduled to run nightly, and the running user does not have administrative privelages, the task is failing to start. The application is requiring to be elevated. It has the UAC shield overlay. The application has no RT_MANIFEST resource, and the compatibility option Run this program as administrator is disabled (per-user and all users). So all that's left is some secret global setting. i know user-specified compat flags are stored in: HKEY_LOCAL_MACHINE \SOFTWARE \Microsoft \Windows NT \CurrentVersion \AppCompatFlags \Layers

  • File auditing software for Windows Server 2003

    - by David Collantes
    I am looking for a program or program suite that will allow the auditing of network shared resources (specifically storage space), and render reports (who created, deleted, moved, modified files, etc). Yes, I know I can turn on auditing on Windows, but the Event Log isn't quite the "charmer" for the job.

  • WEIRD netstat behavior on Windows XP re: www.partypoker.com

    - by tbone
    I really don't know if this is the right place to ask this, but I would really appreciate if someone that is more savvy on Windows XP (Professional) could help me out. For background, I am a 10+ years programmer, so I'm not a total idiot, but I am far from an expert on TCP/IP, etc, and this has me totally confused. When I do a netstat (on Windows XP) I seem to always get a huge amount of www.partypoker.com connections and I can't figure out where they are coming from. A netstat -o shows me that some are coming from PID xxx, which is firefox, but if I kill it, the connections still remain. Some are coming from PID 0, which makes no sense to me. SECOND PROBLEM: One would think you could edit the C:\WINDOWS\system32\drivers\etc\hosts file to block this, but it seems like my machine is ignoring the hosts file! (I have tried with the DNS client service both enabled and disabled, same result). So I just rebooted, killed all my normal programs, and I can't seem to reproduce the problem. If I was a paranoid person, I would think there was some sort of an intelligent trojan running. I am running Windows XP Pro, Kaspersky Antivirus, ccCleaner, and am fully up to date on Windows Update. What gives???? So, I guess my questions are: 1. Is anyone else seeing these wird connections to partypoker.com? 2. Why isn't my hosts filter working? 3. Is there some utility I can run to find out whats happening? I've tried autoruns.exe from sysinternals but don't see anything interesting. Am I the only one with this problem? If there are any additional things you need me to run, let me know.

  • How do I block IP addresses in SuSEFirewall?

    - by Evgeny
    Does SuSEfirewall in OpenSuSE 11 provide an easy way to block all traffic from a list of IP addresses? Ideally just a textfile into which I can put all IP addresses I want blocked, otherwise some configuration option. I've looked through /etc/sysconfig/SuSEfirewall2, but haven't been able to find anything like that.

  • Problem with testsaslauthd and kerberos5 ("saslauthd internal error")

    - by danorton
    The error message “saslauthd internal error” seems like a catch-all for saslauthd, so I’m not sure if it’s a red herring, but here’s the brief description of my problem: This Kerberos command works fine: $ echo getprivs | kadmin -p username -w password Authenticating as principal username with password. kadmin: getprivs current privileges: GET ADD MODIFY DELETE But this SASL test command fails: $ testsaslauthd -u username -p password 0: NO "authentication failed" saslauthd works fine with "-a sasldb", but the above is with "-a kerberos5" This is the most detail I seem to be able to get from saslauthd: saslauthd[]: auth_krb5: krb5_get_init_creds_password: -1765328353 saslauthd[]: do_auth : auth failure: [user=username] [service=imap] [realm=] [mech=kerberos5] [reason=saslauthd internal error] Kerberos seems happy: krb5kdc[](info): AS_REQ (4 etypes {18 17 16 23}) 127.0.0.1: ISSUE: authtime 1298779891, etypes {rep=18 tkt=18 ses=18}, username at REALM for krbtgt/DOMAIN at REALM I’m running Ubuntu 10.04 (lucid) with the latest updates, namely: Kerberos 5 release 1.8.1 saslauthd 2.1.23 Thanks for any clues.

  • Reviewing firewall rules

    - by chmeee
    I need to review firewall rules of a CheckPoint firewall for a customer (with 200+ rules). I have used FWDoc in the past to extract the rules and convert them to other formats but there was some errors with exclusions. I then analyze them manually to produce an improved version of the rules (usually in OOo Calc) with comments. I know there are several visualization techniques but they all go down to analyzing the traffic and I want static analysis. So I was wondering, what process do you follow to analyze firewall rules? What tools do you use (not only for Checkpoint)?

  • XP Suddenly asking for password

    - by ProfKaos
    Is there any sane explanation for a client's Acer Aspire 1 netbook, running XP Home SP 2, suddenly starting to ask for a login password at boot? He has a strict policy of not using passwords, and I removed his login password weeks ago. The story is that suddenly this morning, for the first time, it is asking for a login password.

Any ideas? Thank you for ahead.

  • How is my password sent across when I check gmails/access bank site [closed]

    - by learnerforever
    What encryption is used when my password is sent across in gmails/when I do online banking? RSA? DSA? Public-private key encryption?. In key encryption, which entity is assigned a public/private key? Does each unique machine with unique MAC address has a unique public/private key? Does each instance of browser have unique key? Does each user have unique private/public key? How does session key come into picture? How do machines receive their keys?

  • Why do we need Hash by key? [migrated]

    - by Royi Namir
    (i'm just trying to find what am I missing...) Assuming John have a clear text message , he can create a regular hash ( like md5 , or sha256) and then encrypt the message. John can now send Paul the message + its (clear text)hash and Paul can know if the message was altered. ( decrypt and then compare hashes). Even if an attacker can change the encrpyted data ( without decrypt) - - when paul will open the message - and recalc the hash - it wont generate the same hash as the one john sent him. so why do we need hash by key ?

  • How do I securely execute commands as root via a web control panel?

    - by Chris J
    I would like to build a very simple PHP based web based control panel to add and remove users to/from and add and remove sections to/from nginx config files on my linode vps (Ubuntu 8.04 LTS). What is the most secure way of executing commands as root based on input from a web based control panel? I am loathe to run PHP as root (even if behind an IP tables firewall) for the obvious reasons. Suggestions welcome. It must be possible as several commercial (and bloated, for my needs) control panels offer similar functionality. Thanks

  • Is there an SSL equivelent to an ssh agent?

    - by Matthew J Morrison
    Here is my situation: There are a number of developers who all need to have access to be able to install ruby gems and python eggs from a remote source. Currently, we have a server inside our firewall that hosts the gems and eggs. We now want the ability to be able to install things hosted on that server outside of our firewall. Since some of the gems and eggs that we host are proprietary I would like to somewhat lock access to that machine down, as unobtrusively as possible to the developers. My first thought was using something like ssh keys. So, I spent some time looking at SSL mutual authentication. I was able to get everything set up and working correctly, testing with curl, but the unfortunate thing was that I had to pass extra arguments to curl so it knows about the certificate, key and certificate authority. I was wondering if there is anything like the ssh agent that I can set up to provide that information automatically so that I can push the certificates and keys to the developer's machines so the developers don't have to log in or provide keys each time they try to install something. Another thing that I want to avoid is having to modify the 'gem' command and the 'pip' command to provide keys when they make the http connection. Any other suggestions that may solve this problem (not related to ssl mutual auth) are also welcome. EDIT: I've been continuing to research this and I came across stunnel. I think this may be what I'm looking for, any feedback regarding stunnel would also be great!

  • Open ports in Windows 7, firewall, public network, port 445

    - by chris
    I selected "public network" in Windows 7. Windows is listening on TCP port 445: TCP 0.0.0.0:445 WIN7TEST:0 ABHÖREN The corresponding incoming firewall rule isn't activated (4th column): When I choose "workplace network" the SMB incoming port 445 rule is still disabled in the advanced windows firewall configuration. I thought "public network" / "workplace network" and so on is influencing the windows firewall rules!? Where's the difference between workplace and public network then? http://www.abload.de/image.php?img=winfire2nxku0.png

  • zip password crack possible?

    - by tm1rbrt
    I have a piece of software i have to install on company laptops. The installer needs a serial to work properly, but i don't have it (my manager isn't here so i cant ask him). The installer tells me to ring a phone number which doesnt appear to be connected anymore. I would download win32dasm and ollydbg and have a go at cracking the installer but i dont really have time and i havnt done it in years. There is a zip file on the disc that looks like it contains all the program files but it is passworded. Is it feasible to crack this or will it take ages?
