Mail Admins be wary of failed AUTH LOGIN attempts on your mail server

August 2007

With the amount of dynamic broadband ips blocked by mail servers, spammers are hacking legit mail server in an attempt to get alternative avenue to send out spam.

Beware of spammers are attempting to authenticate themselves by login as users in your domain. Change all single English word passwords to something illegible or combine it with any special characters like %*+!, etc.

Some the common password that they try;

hr
leader
info
master
manager
super
passwd
password
pass
root
rsb
webmaster
test
!@#$%^&*
%null%
%username%
%username%12
%username%123

Many of the above passwords, I've seen being used by actual users of domains that I've encountered.

Password like %username% / %username%12 and %username%123 are meant to be replaced by the automated script with actual email user names but the brain-dead script written by its likewise programmer doesn't function as it should.

What is phishing? - March 2007

Phishing is basically an attempt by scammers to collect information about your login details to your bank and other financial organization, which has an online presence.

Most of these information phishing are done through spam. If your email client is set to read email in html format, you will see an image with the official logos and layout of the organization that the phishers are phishing information for.

Among the many type of know phishing method, the most popular one is the rock phish.

The url generated by a rock phish is also unique in the sense that the url used although all resolve to the same destination, has a uniquely generated number embedded within the url.

Domaintools.com is a tool to check for number of domains in a particular ip address. If a victim falls for the phishing attempt, the scammer utilizes the information obtained in the following order;

Local banks are targeted as well. Some phishing are specially crafted for Singapore banks like OCBC and DBS.

How to get removed from Spamcop's blacklisting? - 16th Oct 2006

You could have erroneously enable your box trapper or the autoresponder option for your email addresses permanently.

What happen is probably the spammer send emails to your email addresses that are known by them to auto respond with a message and they use Spamcop's known spamtrap addresses as the return addresses for these mails.

Once your autoresponder replied to the spamtraps too often, you will get yourself blacklisted.

This is done by the spammers to firstly generate anger against Spamcop and secondly to cause enough legitimate domains to be blacklisted to generate distrust towards Spamcop as a reliable source for blacklisted ip addresses.

Thus when the law catches up on it, the money mules are the one getting arrested and their bank account frozen while the scammers remain untraceable.

The preferred hosting provider for such fake job sites is Yahoo hosting probably because they are too big to be able to act fast on such sites and also the setup of hosting package is easily done with a credit card with stolen card details.

Sony Distributing Spyware

Sony, in their futile digital rights management efforts, has taken to playing dirty with the music CDs. Multiple security sources are confirming the existence of spyware in the form of rootkits on Sony's music CDs. This behavior is unethical in the eyes of many and the legality may be questionable as well.

This unethical behavior by Sony shows the lengths companies are willing to go to protect the music. Passing around malware in the form of rootkits could create real problems for many computer users and possibly leave them susceptible to other hackers in the future. The whole purpose of this rootkit is to be sneaky and stick stuff in they don't want you to know about.

F-Secure went on to say Sony BMG is using the rootkit-based DRM (*Digital Rights Management Program) on some CDs sold in the U.S. and the system may have been in use since March of 2005.

When a flaw is known, exploits will be available just as quickly.

Stung by continuing criticism, the world's second-largest music label, Sony BMG Music Entertainment, promised Friday to temporarily suspend making music CDs with antipiracy technology that can leave computers vulnerable to hackers.

Sony's announcement came one day after leading security companies disclosed that hackers were distributing malicious programs over the Internet that exploited the antipiracy technology's ability to avoid detection. Hackers discovered they can effectively render their programs invisible by using names for computer files similar to ones cloaked by the Sony technology.

More information about XCP.Sony.Rootkit

The rootkit techniques make Sony's (DRM) program virtually undetectable on Windows systems.

What is rootkit technology? - Rootkits are a technology that can hide any trace of themselves and can hide other software, files, data, etc. that's running on a PC. Therefore, rootkits compromise your PC's security by enabling undetected access to it by intruders.

How does it affect my computer? - Rootkit technologies, like the one deployed by Sony on some of its music CDs, can be abused by malicious hackers to hide their own programs on your computer without your knowledge. This makes it seem as if attacks are coming from your PC not theirs.

This would seems mild as in our opinion rootkits were supposed to not just hide programs but also allow root (administrator) access to the compromised machines.

How do I uninstall it? - Even sophisticated PC professionals have a hard time removing Sony's rootkit manually. Fortunately, CA's eTrust(r) PestPatrol(r) detects and removes Sony's rootkit technology upon normal software installation process.

Does eTrust PestPatrol remove Sony's entire rootkit? - eTrust PestPatrol detects and removes the harmful elements of Sony's rootkit technology including:

  • The Rootkit itself (that's the part that hides files)
  • The installer
  • The patch installer
  • The media player

CA is actively working towards giving PestPatrol the ability to safely remove the entire rootkit including the XCP.Sony.Rootkit portion. This remaining feature of Sony's rootkit protects them against music piracy. While this feature limits your ability to share your Sony music, it does not compromise your PCs security.

New Worm Hits Windows

August, 2005

Affects: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows XP, but Windows 2000 most seriously

The worm hits at an security hole in the follwing critical update released last week, which may have not been rolled out by administrators on their network.

Security Update for Windows 2000 (KB899588) Overview A security issue has been identified in the Plug and Play service that could allow an attacker to compromise your Microsoft Windows-based system and gain control over it. You can help protect your computer by installing this update from Microsoft. After you install this item, you may have to restart your computer.

Download the update here

Zotob.a and Zotob.b are the first variants of a new worm which uses the MS05-039 vulnerability as a means of propagation.

Zotob.a then makes a copy of itself on the system named %System%\botzor.exe. Zotob.b copies itself as %System%\csm.exe. Then it adds the appropriate value to the

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run and HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices registry keys:

"WINDOWS SYSTEM" = "botzor.exe" or "csm Win Updates" = "csm.exe"

It then sets the value:

"Start" = "4" in the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess in order to disable Windows Shared Access service.

Update your Windows 2000,
restart in Safe Mode remove the above registry entries,
search for and remove botzor.exe or csm.exe,
restart system,
press Ctrl-Alt-Del and look for suspicious process,
terminate it,
update your virus definitions and
do a throrough scan of your system.

The worm spread via TCP 445 which is by default blocked from WAN port except those with leased lines and public IPs. Thus it won't affect most companies (even those that may not have patched their systems) that does not allows

  • remote access to users,
  • guest users from outside the network,
  • no mobile users on the network,
  • no unsecured wireless network,

This worm hits at machines in the local subnet, so once a single node is infected, all the rest within the network will be infected as well unless they are firewalled on their port 445.

Home users are likely to be affected if they connect to the Internet directly via their cable modems or ADSL modems without a firewall, as all ports on their system will be open to attacks.



libsysmgr

(libsysmgr.exe) A spyware that takes control of your system and restrict access to system tools like regedit.exe, etc. It starts up as a service thus can be quite difficult to remove.
Remove by deleting the file libsysmgr.exe after going into command prompt in safe mode. Then run regedit and clear off any traces of it from the registry.

Other spyware programs that launch at startup;

winstat.exe - spyware (ID 453075918)
system32win32.exe, winstat.exe, winstatkeep.exe - spyware (ID 453076082)
nhksrv.exe - spyware
snapple.exe - virus ??
autoexe.exe - virus/trojan
sysformat.* - virus
winnep.exe - virus ??
SahAgent.exe, SahDownloader.exe, WEBinstaller.dll - spyware (ID 453076082)
winsync.exe or winsync - spyware (ID 453077096)
y! blue stat 4.exe and y_blue_stat.exe - spyware (ID 453079583)
dialler.exe - spyware (ID 453073355)

It is getting difficult to tell spywares from viruses as spywares are getting more and more like viruses and vice versa. Today's viruses are becoming tools for spammers to collect your email addresses and even those addresses that you rarely use are harvested once anyone of the people you are corresponding with gets infected with a virus.

Microsoft's very own anti-spyware software. It has rated as better than those free spyware removal tools (spybot search & destroy/Adaware from Lavasoft) currently available.

Download the Anti-Spyware software here

Like any typical Microsoft product, when it starts, it refuses to go away and stays in the background. This present beta version is free but you may need to purchase it in order to use once the full version is available.

Beware of so-called anti-spyware softwares that are spywares themselves;

Spy Wiper, AdWare Remover Gold, BPS Spyware Remover, Online PC-Fix SpyFerret, SpyBan, SpyBlast, SpyGone, SpyHunter, SpyKiller, SpyKiller Pro, SpywareNuker, TZ Spyware-Adware Remover, xp-AntiSpy, SpyAssault, InternetAntiSpy, Virtual Bouncer, AdProtector.
