• Architecture diagram of a computer virus

  - by Shiraz Bhaiji

  I am looking for an architecture diagram of a computer virus. Does anyone have a link to a good example? Edit Looks like I am getting hammered with downvotes. I agree that there is no single architecture for a virus. But somethings must be included for a program to be a virus. Example for components in the SAD: Replication method Trigger Payload Hosts targeted Vulnerabilities targeted Anti detection method

• Pourquoi ne pas laisser les développeurs et le public choisir ? Le PDG d'Adobe répond à la lettre ou

  Mise à jour du 30/04/10 NB : Les commentaires sur cette mise à jour commencent ici dans le topic Pourquoi ne pas laisser les développeurs et le public choisir ? Le PDG d'Adobe répond à la lettre ouverte anti-flash de Steve Jobs C'est en substance la réponse de Shantanu Narayen : si notre technologie est si mauvaise et si « inadaptée à l'iPhone » (comme l'écrit noir sur blanc Steve Jobs - lire ci-avant), les développeurs ne l'utiliseront pas et les consommateurs s'en détourneront.

• what kind of certificate needed for my application ?

  - by e e

  I am releasing free C# softwares I've created using Visual Studio. In the future, some of these softwares might become Paid. I was wondering if I need to purchase any kind of license for them ? I understand that it's good to have a certificate for your website (SSL?), if your trying to sell your software but what about your applications ? I just don't want anti-virus/browsers flagging my application as not trusted. Any suggestion is appreciated.

• Legal Applications of Metamorphic Code

  - by V_P

  Firstly, I would like to state that I already understand the 'vx' applications for Metamorphic code. I am not here to ask a question related to any of those topics as that would be inappropriate in this context. I would like to know if anyone has ever used 'Metamorphic' code in practice, for purposes other than those previously stated, if so, what was the reasoning for using said concept. In essence I am trying to discover a purpose for this concept, if any, other than circumventing anti-virus scanners and the like.

• Is Windows Server 2008R2 NAP solution for NAC (endpoint security) valuable enough to be worth the hassles?

  - by Warren P

  I'm learning about Windows Server 2008 R2's NAP features. I understand what network access control (NAC) is and what role NAP plays in that, but I would like to know what limitations and problems it has, that people wish they knew before they rolled it out. Secondly, I'd like to know if anyone has had success rolling it out in a mid-size (multi-city corporate network with around 15 servers, 200 desktops) environment with most (99%) Windows XP SP3 and newer Windows clients (Vista, and Win7). Did it work with your anti-virus? (I'm guessing NAP works well with the big name anti-virus products, but we're using Trend micro.). Let's assume that the servers are all Windows Server 2008 R2. Our VPNs are cisco stuff, and have their own NAC features. Has NAP actually benefitted your organization, and was it wise to roll it out, or is it yet another in the long list of things that Windows Server 2008 R2 does, but that if you do move your servers up to it, you're probably not going to want to use. In what particular ways might the built-in NAP solution be the best one, and in what particular ways might no solution at all (the status quo pre-NAP) or a third-party endpoint security or NAC solution be considered a better fit? I found an article where a panel of security experts in 2007 say NAC is maybe "not worth it". Are things better now in 2010 with Win Server 2008 R2?

• Spammer relaying via Postfix mail server

  - by Paddington

  I have a Plesk 9.5 mail server (cm.snowbarre.co.za) on Ubuntu 8.04 LTS which forwards all SMTP traffic to an anti-spam server cacti.snowbarre.co.za. Many times I see the headers on the anti-spam server to contain from addresses not hosted on the mail server and I have checked and confirmed that my server is not an open relay server. How can a spammer be using my server to relay spam traffic? How can I stop this? Open relay test: paddington@paddington-MS-7387:~$ telnet cm 25 Trying 196.201.x.x... Connected to cm.

• Preferred mail system/server for a company?

  - by Trevoke

  Say you are responsible for setting up an email solution at a company. Which would be your choice? I know of the following options, but many of them not well: Gordano Mail System Exchange Exim Postfix Qmail Zimbra For having used it a little over two years, I really, really like Gordano Mail System. They offer a whole bunch of things, like calendaring, anti-spam, anti-virus, extremely complete and filterable logging options, aliases, a customizable webmail interface... And their software can be installed on both a Windows or Linux OS. In addition, their support is top-notch, their knowledgebase comprehensive (and, I will admit with a touch of pride, I have contributed, with my questions, to the addition of a few articles in there). Of course, they're not free, which can be a problem, but they're not Exchange, and they do offer pretty much everything that Exchange offers -- which is great if you want to stay away from that, but need all the features. Although, if you need a Blackberry Exchange Server, or something similar, I'm not sure what you should go for. So.. What would your choice be? Why? I've never played with a more DIY email solution, but I'm sure many people here have and wouldn't trade their setup for the world :)

• I cannot access Windows Update at all

  - by Cardinal fang

  I have been unable to access the Windows update site for a couple of weeks now. I just get a message saying "Internet Explorer cannot display the webpage" and saying I have connection problems. Same thing is replicated with any other Microsoft site I try to access. The Automatic Updates also do not work. I can access every other wesbite I've surfed to. I've tried Googling the problem and based on what other site have suggested I have cleared my cache and temp files. I've scanning my hard drive with my antivirus in case I have a virus (nada). I've tried turning off my firewall and anti-virus (I run Zone Alarm). I've downloaded SpyBot and scanned my drive with that in case something was missed by Zone Alarm (again nada). Based on suggestions from the smart cookies on the Bad Science forum, I've used nslookup to check my translation isn't wonky (got all the info they said I should get). I've also tried navigating there directly using the IP address I was given (nope). I normally access the internet through a 3 mobile broadband connection, but have also tried connecting using a mate's wi-fi connection in case it was something on my mobile modem interferring. I run Windows XP SP3 with Internet Explorer 7 and Zone Alarm Internet Security Suite as my anti-virus/ firewall. Any suggestions?

• Why are certain folders in my XP network share really, really slow?

  - by bikefixxer

  I have a workgroup set up with Windows XP. My file "server" is running XP Pro and the clients are running XP home. I've turned simple file sharing off on the server because certain clients need access to certain folders and not to others, and I want to keep it that way. Therefore, I've used the granular sharing/security settings to enable certain clients access to certain folders. I'm using the net use command in a batch file on the clients to add the share when they logon so it's always available via a mapped drive or a shortcut. On some clients "My Documents" points to the mapped drive, but all of the local and application settings stay local. Everything works well except for accessing a certain folder on the network. It contains a lot of random batch files and self-executable programs I use for diagnostics and what not, and nearly every time I open the folder the computer hangs for 15-60 seconds. This happens on every machine, including the server (but not nearly as often as the clients). I've searched high and low and cannot figure it out and it's driving me crazy. Here are all the things I've tried to no avail: Disabled firewall (XP) and anti-virus (ESET NOD32) Deleted any desktop.ini file I can find in the share Disabled "automatically search for network folders and printers" Disabled "remember each folder's view settings" Set HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer NoRecentDocsNetHood = 1 Tried with mapped drives and with UNC shortcuts Ran CHKDSK Removed Read-Only attribute from all folders (well, tried to remove, it always came back on with a half check) Added the server's static IP to the hosts file on the clients I've tried monitoring the server's performance to see if anything makes sense. Occasionally the issue coincides with a spike in pages/sec (memory) but not always. Other than that, everything else seems normal. The anti-virus would seem to be the most likely cause to me considering the batch files and what not, but it still hangs when it is completely disabled. I'm at a loss and if anyone can help me with this I'd greatly appreciate it!

• Using sed to Download ComboFix automatically

  - by user901398

  I'm trying to write a shell script to grab the dynamic URL which ComboFix is located at at BleepingComputer.com/download/combofix However, for some reason I can't seem to get my regex to match the download link of the "click here" if the download doesn't work. I used a regex tester and it said I matched the link, but I can't seem to get it to work when I execute it, it turns up an empty result. Here's my entire script: #!/bin/bash # Download latest ComboFix from BleepingComputer wget -O Listing.html "http://www.bleepingcomputer.com/download/combofix/" -nv downloadpage=$(sed -ne 's@^.*<a href="\(http://www[.]bleepingcomputer[.]com/download/combofix/dl/[0-9]\+/\)" class="goodurl">.*$@\1@p' Listing.html) echo "DL Page: $downloadpage" secondpage="$downloadpage" wget -O Download.html $secondpage -nv file=$(sed -ne 's@^.*<a href="\(http://download[.]bleepingcomputer[.]com/dl/[0-9A-Fa-f]\+/[0-9A-Fa-f]\+/windows/security/anti[-]virus/c/combofix/ComboFix[.]exe\)">.*$@\1@p' Download.html) echo "File: $file" wget -O "ComboFix.exe" "$file" -nv rm Listing.html rm Download.html mkdir Tools mv "ComboFix.exe" "Tools/ComboFix.exe" -f The first two downloads work successfully, and I end up with: http://www.bleepingcomputer.com/download/combofix/dl/12/ But it fails to match the final sed that will give me the download link. The code it's supposed to match is: <a href="http://download.bleepingcomputer.com/dl/6c497ccbaff8226ec84c97dcdfc3ce9a/5058d931/windows/security/anti-virus/c/combofix/ComboFix.exe">click here</a>
