Ubuntu Security :: Hotmail And Gmail Accounts Hijacked
Sep 8, 2010
I recently received an email from a friend without subject and just a link. Since we do that a lot, I clicked on it. I was taking to a website that looks like a phishing site and my computer hard drive started working feverishly. I closed it quickly.
First, I want you guys to be aware of this thing since it seems to be fairly new.
Second, I want to know if I have been compromised. I already changed the password on my gmail account and I accessed the site using Ubuntu and Firefox.

I have a lot of emails on hotmail and gmail that I want to store in text or html files on my local Fedora computer for future reference. Is there a way I can download them to my hard drive without doing it one email at a time with the browser's Save Page As feature or some such thing? There has to (?) be a better way.
Every mail program should have an easy-to-use 'mass' export-to-text-file feature so that people are not held hostage to a particular email service or program. The lack of such a feature in email programs I've used is one of my pet peeves. It seems rather tyrannical and abusive. (Now before someone tells me it's a free service, please remember all the advertisements I have to go through to use the service). I do not have an email account through an ISP. I live with my landlord who deals with the ISP. I only use hotmail and gmail (and, rarely, yahoo).

I have been trying to figure out how to keep my company's email from being treated as junk mail by Hotmail, Yahoo & Gmail for over a year.
When I acquired the company its email was hosted by sina.com as its in China. It was being run under a windows server and had issues sending & receiving.
I moved it to a linux server system in Hong Kong that has a US co-host site in Chicago area thinking its got to better than whats running in China.
We are still having problems sending emails to hotmail, yahoo and gmail.
My entire company is about ready to redmond our company email and use their personal webmail accounts.

I have evolution set up to send emails using gmail's smtp server. I've always been able to do it with no problems, but a couple of days ago I stopped being able to send emails to gmail accounts. I can send emails to other addresses but not gmail. The same happens with my wife's laptop with ubuntu. The only thing I can think of is that we recently moved and thus changed ISP, but I don't see how that's preventing us to send mails specifically to gmail accounts...

I tried to get to the logs and then realized that the entre system had been hijacked the remote desktop icon was active there was a message in gnote saying "youve been own3d". The system Is a old mac mini PPC system and i plan on looking at the system log with a netboot cd by running linux rescue at boot. my question is how do i gain access to the system log from a rescue cd to find out how much damage this hacker did?

After reading everything that says you don't need an anti-virus for Linux. OR Linux doesn't get viruses. Guess what I have a Virus. I don't know which one, but it is sending out spam emails from my webmail, MSN, account. I do not have a local client installed. I am guessing it is linking into MSN through Pidgin, getting the addresses there, and sending the spam, somehow, through MSN. Actually one MSN and one Hotmail account. I also have not been able to find an anti-virus program for Ubuntu. There do not seem to be any listed in the software repositories that Ubuntu links into. How do I get rid of it? My contacts are starting to get upset.

I have upgraded to Lucid, but was having the same issues on Karmic. I made a 2nd user acct we'll call X and we'll call the original acct Y. All of these issues only happened after creating X.
On X I have: sound Things wrong with X: I don't have the ability to modify any folders (even ones that are made from X's acct), I can't change the password or even access the Users and Groups, I can't modify any browser settings in Firefox but can on Chromium, the option for wireless is completely gone
On Y I have: the ability to access users and groups, the ability to modify all folders on either acct, the ability to change any settings on anything Things wrong with Y: no sound (doesn't even show the driver, but the driver is there on X's acct), wireless is completely gone (just like X's acct), even though I can access Users and Groups I cannot modify anything about X's acct
My first thought was to completely delete X since that's when all the problems began, but I'm afraid that since X seems to have "stolen" my sound card, that will be lost forever. I am also afraid that since neither account has wireless deleting X might hinder ever getting it back.

allow sftp access to my Ubuntu system (happens to be desktop as it's also my main system) using accounts that are not able to login normally. (I have already managed to create such accounts.) These accounts need to be chrooted (also already accomplished with the openssh daemon settings.) Where I run into problems is that I want to give them (read only) access to files outside the chroot (on another partition in fact) and the matter if made more difficult because the directories to be shared are on NTFS-3G partitions (as they are a shared linux / windows storage drive). Is this possible and if so, what do I need to do?
Edit - Forgot to include versions
Ubuntu 10.10
openssh 1.5.5p1-4ubuntu4 (the one that comes with 10.10)

Once again, nobody seems to understand security properly when they decide to add nifty new features. After upgrading to 10.04 from 9.10, I now have a listing of all the user accounts under "Switch from" when I go the the logout menu at the upper right side of the task bar. This is a terrible security hole that should never have been allowed in the first place, and is just as annoying as the default behavior of listing all the user accounts on the login screen.

I have an encrypted /home partition but would like to set up a guest account for my brother. Obviously, encryption doesn't work so well when you give out the key so what I'd like to do is specify a different, unencrypted location as a home directory for the guest account so he doesn't need access to that partition. Is there a way of doing this?
I've got fedora 10, dual boot with windows, 2 hard drives, 1st is NTFS windows. 2nd is split into a swap, ext3 for the OS, and an encrypted partition for /home.

fedora 10 and im trying to set up some user accounts on a computer. My current problem is that we set up 2 root accounts and we need both to be able to authenticate. So far this works on the command line but whenever i'm on the GUI it seems that it only allows root to give its password for things. How do i enable the second account to do that as well.as a note, i am doing this for someone else so i have little to no control how this is set up, so please, i am not looking for reasons why this is not a good idea i would just like to figure this out

I am looking at creating two user accounts for "contract system admins"..These guys will be performing sys admin duties for a sever -- however, I am still concerned about security of data. For example, the server contains password information for our database, etc.Besides making them sign an NDA, etc. what other security mechanisms could I put in place to ensure that they don't just go buck wild. For example, when someone makes a sudo command, is this logged?
what are some recommendations for general security practices?

I want to use AD sys accounts to logon to linux servers. What is the best and most secure way to do this. This because we want to ensure it is tracable when a server administrator makes changes to a linux server. Now we use root to make changes to the servers.

way to automate adding and removing users from 10 different Fedora 7 servers. We use them as print servers and our users have a user name and password to authenticate with when printing. We also use Samba to talk to a W2k3 server that tracks and charges the users for what they print. The set up was done by a vendor and after 6 months of being in production the scripts they created has flaws.
I need a way for a script to run as often as possible that will remove, change, or delete user accounts from the servers and from Samba. how to most effectively achieve this?
It would be ideal to have a file that gets written to when a change needs to be made then a script to make these changes?

My Linux is Fedora release 13. I found there are a few users created not by me. I am not sure if the system got hacked somehow. Then the hackers created these users, i.e. (1) oracle, (2) exim, (3) test, (4) cox. I tried to delete all of these four users by using "usrdel" command but the system said "I cannot delete these users as the users are logging in". If my system got hacked ?? or these users are created by the system itself?

I would like to restrict a few selected accounts to minimum of 15 characters passwords. Other accounts,however, should still be able to login with 8 character passwords. This is in RHEL 5. Does anyone know how to go about it? I have checked PAM documentation and pam_cracklib.so has an option minlen. As per its documentation, minlen can force users to use 15 characters, but it forces every account on the system. I might be wrong too.

I am trying to disable accounts after 5 unsuccessful login attempts. I am following the guidelines in this article:
[URL]
This is on an Oracle Enterprise 5.4 box, which is essentially RHEL 5.4 Here is what my /etc/pam.d/system-auth looks like:
--------
#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
[code]....
Unfortunately, the account does not seem to be locked or disabled. As root, runninng 'su test2 -c <some-command>' always sucessfully runs <some-command>, and leaves the failed attempt count at 6. /etc/shadow does not have an * or ! anywhere in the encrypted password for the 'test1' user.
What am I doing wrong? I thought that with the max attempts set to 0 in faillog, that the deny= parameter would be used. I thought I should be using su <user> -c <command> from the root account to test if the disable feature is working.

The problem is here:When I was open gmail in my system Certificate Error is coming. The error details:
This Connection is Untrusted You have asked Firefox to connect securely to url, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do? If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

We have 4 servers having rhel 5.2. We have several users logged in on one of them. We have nis server/client running on them and have common home area mounted on all of them. Now we want to disable/block the accounts of the users who have not accessed our servers in last 2 months from today.What logic should we apply to do so? We were checking stat of .bashrc of each user but is not correct logic. We are going to write shell script for the same. We dont want to do anything in users home area or their files.

This used to work in Fedora < 15. Whenever I want to send an e-mail using Gmail's SMTP server for the first time in a given session, the KWallet system asks if I would not rather migrate the password and store it encrypted inside a wallet. Every time I concur and every time an error message pops-up, as soon as I try and send another e-mail. The attached snapshot shows the error message I get. It doesn't matter how many times I select "Store Password". Every time the ordeal is the same. Up to Fedora 14 this method worked all right, but now it fails.

Problem: My Email Address is spamming Situation Chronology: 1. I received an email (spam) on Yahoo Mail from someone who was not intending to send it. (While it did go to spam folder, I did 'open' the email (since it came from a trusted sender) but it only contained a link (which because of WOT) I assumed was spam.) I did NOT click the link. 2. I then informed him that his email addy was spamming.3 Shortly thereafter, i noticed in Ubuntu (firefox) whenever I clicked "reply" to email back to someone, there was a quick flash of letters/numbers in the slot where I would normally write. This instantly disappears and goes blank so I can write something, so I just figured it was a bug.
