A small clarification, I nearly posted this yesterday but it didnt seem appropriate or required at the time... Im one of the helpdesk team at the ISP Lin also works for. Our helpdesk is familiar with Outlook Express but that doesnt mean we're close minded about it. We regularly support clients who use other mailing software and as long as the software is reasonably generic we manage. We dont force our clients to use OE, but we do suggest it to our clients *because its there*. The differentiation is important, and stereotyping against helpdesk types isnt going to help. We all start somewhere. :-) I run Eudora in Sponsored mode and find it more than adequate - never caught anything through that, and I have never run resident antivirus either. (I manually scan my system from time to time using F-Prot for DOS.) Prior to using Eudora I used Netscape Messenger (4.x) and found this was also pretty good, although the limitation to only one mailbox is what forced me to migrate. Now that Netscape 7 is out I may consider switching back soon.... I think most ISP helpdesks crewed by reasonable people will accept that their clients dont *have* to use Outlook Express, and the only reason they may encourage their clients to use it is that especially for the less-than- technically-savvy sort, OE is easy to setup, and provided with all versions of Windows from 98 upward. If you work for an ISP and you dont have support staff familiar with a broader range of email clients than Outlook and Outlook Express, I would seriously suggest some more training is in order: Eudora, Netscape Messenger and Pegasus come to mind as alternatives, but theres obviously a lot more. </end rant> Mark. - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

I'm not really happy that this sort of posting meets the AUP, which talks about discussion between operators. There are cetainly announcements which may be of value to the list, but these seem to me to be characterised by not being present on a routine basis in other forums. I think that to allow announcements of this kind would have an unacceptable effect on the signal to noise ratio of the list. Unless people particularly want to see these here, I intend in future to treat them as outside the AUP. - Donald Neal NZNOG List Administrator > E-Secure-IT has just received this field report: > > While it does all the normal mass mailing stuff, own smtp engine, > harvests address lists etc this one did something really weird that > I've never seen before- it sent a postscript print job to > every printer > it could find. > > The scary thing was it even picked up printers attached to parallel > ports and which were not shared and sent the print job to them too. > I know it tries to access network shares, but looks like it tries to > access print q's also, be interested to see if anyone else has > seen this? > > FYI can confirm that NAV sigs of 30/9 do detect and clean. > > Arjen > www.e-secure-db.us ------------------------------------------------------------------------------ "This communication, including any attachments, is confidential.

E-Secure-IT has just received this field report: While it does all the normal mass mailing stuff, own smtp engine, harvests address lists etc this one did something really weird that I've never seen before- it sent a postscript print job to every printer it could find. The scary thing was it even picked up printers attached to parallel ports and which were not shared and sent the print job to them too. I know it tries to access network shares, but looks like it tries to access print q's also, be interested to see if anyone else has seen this? FYI can confirm that NAV sigs of 30/9 do detect and clean.

Hi Joe, We could state that in our advisories, However, wouldn't it be on the same line as: Avoid car accidents, disable all petrol and diesel? Personally I would love to have the death rate on the road reduced to 0. If this is realistically achievable right now is another question. The reality is that Microsoft and all its products are a very large part of the global business world right now. Just as unsafe cars. We can make them somewhat safer by awareness and vigilance, just as driving a car. That is not to say that we don't agree with you, but the other side of the coin is that there are plenty of "non-windows" threats around; SSL, apache etc also have their own vulnerabilities.

I think ISP and IT helpdesks of the world would do everybody a big favour if they just stopped supporting mail clients which make it so trivial to execute encapsulated scripts.

The same could be said of the Internet, as more and more countries pass legislation on what is and isn't acceptable use of this medium. If nobody took any steps to pass and police these laws then more software vulnerabilities would be discovered and exposed by, what can arguably be explained as the biggest pain in our collective IT butt, Hackers, or did I mean developers that move from the standard to claim their own. >If the most popular car on the road had a defect which routinely caused >people to die, I don't think people would say "the reality is that the >car in question has a large market share, so it's really not practical >to encourage people not to drive it." Fix the defect and do a recall on the car in question, it is not a question of practicality more one of morality, and we all know that practicality and morality are clouded when it comes to the bottom line.

>From www.e-secure-it.us DETAILED DESCRIPTION OF BUGBEAR, HOW TO RECOGNISE AND FIRST AID KIT. Bugbear / Tanatos This virus is written in MSVC and packed with UPX. It shuts down anti-virus and firewall software designed to block out intruders and can spread by dropping copies of itself into folders on shared networks, which are commonly used at corporations and large organizations. The worm's most interesting feature is a Trojan horse component called PWS-Hooker that secretly watches every keystroke on an infected computer, and stores the captured information on the computer in encrypted form. The data can be accessed later by the virus writer or anyone else who happens upon the infected computer, or it can be e-mailed to the author. Bugbear might be spreading because it is cleverly crafted and difficult to spot with the naked eye. It arrives in a victim's e-mail inbox with a subject line chosen randomly from dozens of possibilities, including: Possible message subject lines include the following (however, other random subject lines are also possible): 25 merchants and rising Announcement bad news CALL FOR INFORMATION! click on this! Correction of errors Cows Daily Email Reminder empty account fantastic free shipping! Get 8 FREE issues - no risk! Get a FREE gift! Greets! Hello! Hi! history screen hmm.. I need help about script!!!

Re: $150 FREE Bonus! Report SCAM alert!!! Sponsors needed Stats Today Only Tools For Your Online Business update various Warning! wow! Your Gift Your News Alert The message body varies and may contain fragments of files found on the victim's system. The attachment name also varies, but may contain the following strings: Card Docs image images music news photo pics readme resume Setup song video The actual infected file arrives as an attachment, which also has a random name. And Bugbear's first task, upon infection, is to disable all installed antivirus software. It's throwing a lot of things at people to see if it can find something to slip under the radar. Once activated, the virus shuts down scores of vital processes used by Windows and by antivirus software, records user keystrokes, opens a backdoor to the infected machine for use by attackers, and attempts to mail copies of itself out to other users, randomly generating new subject lines and virus executable names as it does W32/Bugbear-A is an internet worm which spreads via SMTP and also attempts to spread via network shares. The worm copies itself to the Windows system folder as a file with a random four-letter name and an EXE extension and adds to the following registry entry to run this file on the next reboot: HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce W32/Bugbear-A also drops a copy of itself in the Windows start up folder so that is run on system restart. The worm drops a randomly-named DLL file, which is related to logging keystrokes, in the Windows system folder. It can also terminate certain firewall and antivirus programs. How to recognise: The virus file is attached to e-mails with a wide variety of subject lines : Attachment Length: 50,688 bytes (UPXed) or 50,664 bytes The subject line, name of the attachment and text in the body of the message can vary, and the attachment name typically has a double extension, such as .xxx.pif, .xxx.scr etc IF YOU ARE INFECTED: Symptoms: Method Of Infection This virus spreads over the network (via network shares) and by mailing itself (using it's on SMTP engine). It attempts to terminate the process of the following security programs: ACKWIN32.exe F-AGNT95.exe ANTI-TROJAN.exe APVXDWIN.exe AUTODOWN.exe AVCONSOL.exe AVE32.exe AVGCTRL.exe AVKSERV.exe AVNT.exe AVP32.exe AVP32.exe AVPCC.exe AVPCC.exe AVPDOS32.exe AVPM.exe AVPM.exe AVPTC32.exe AVPUPD.exe AVSCHED32.exe AVWIN95.exe AVWUPD32.exe BLACKD.exe BLACKICE.exe CFIADMIN.exe CFIAUDIT.exe CFINET.exe CFINET32.exe CLAW95.exe CLAW95CF.exe CLEANER.exe CLEANER3.exe DVP95_0.exe ECENGINE.exe ESAFE.exe ESPWATCH.exe FINDVIRU.exe FPROT.exe IAMAPP.exe IAMSERV.exe IBMASN.exe IBMAVSP.exe ICLOAD95.exe ICLOADNT.exe ICMON.exe ICSUPP95.exe ICSUPPNT.exe IFACE.exe IOMON98.exe JEDI.exe LOCKDOWN2000.exe LOOKOUT.exe LUALL.exe MOOLIVE.exe MPFTRAY.exe N32SCANW.exe NAVAPW32.exe NAVLU32.exe NAVNT.exe NAVW32.exe NAVWNT.exe NISUM.exe NMAIN.exe NORMIST.exe NUPGRADE.exe NVC95.exe OUTPOST.exe PADMIN.exe PAVCL.exe PAVSCHED.exe PAVW.exe PCCWIN98.exe PCFWALLICON.exe PERSFW.exe F-PROT.exe F-PROT95.exe RAV7.exe RAV7WIN.exe RESCUE.exe SAFEWEB.exe SCAN32.exe SCAN95.exe SCANPM.exe SCRSCAN.exe SERV95.exe SPHINX.exe F-STOPW.exe SWEEP95.exe TBSCAN.exe TDS2-98.exe TDS2-NT.exe VET95.exe VETTRAY.exe VSCAN40.exe VSECOMR.exe VSHWIN32.exe VSSTAT.exe WEBSCANX.exe WFINDV32.exe ZONEALARM.exe TROJAN: Port 36974 open Existence of the following files (* represents any character): %WinDir%\System\****.EXE (50,688 or 50,684 bytes) %WinDir%\******.DAT %WinDir%\******.DAT %WinDir%\System\******.DLL %WinDir%\System\*******.DLL %WinDir%\System\*******.DLL This worm emails itself to addresses found on the local system. The worm copies itself to the Windows system folder as a file with a random four-letter name and an EXE extension and adds to the following registry entry to run this file on the next reboot: HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce When run on the victim machine it copies itself to %WinDir%\System as ****.EXE (where * represents random character). For example in testing: Win98 : C:\WINDOWS\SYSTEM\FYFA.EXE 2k Pro : C:\WINNT\SYSTEM32\FVFA.EXE The following Registry key is set in order to hook next system startup: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion RunOnce "%random letters%" = %random filename%.EXE (Win9x) The worm copies itself to the Startup folder on the victim machine as ***.EXE (where * represents random character), for example: Win98 : C:\WINDOWS\Start Menu\Programs\Startup\CUK.EXE 2k Pro : C:\Documents and Settings\(username)\Start Menu\Programs\Startup\CYC.EXE Trojan component The worm opens a port on the victim machine - port 36794 and searches for various running processes, stopping them if found. The list of processes includes many popular AV and personal firewall products. This remote access server allows an attacker to upload, and download files, run executes, and terminate processes. It drops a DLL on the victim machine - keylogger related. This DLL is detected as PWS-Hooker.dll. Network share propagation The worm attempts to copy itself to the Startup folder of remote machines on the network (as ***.EXE - described above). Outgoing messages look to make use of the Incorrect MIME Header Can Cause IE to Execute E-mail Attachment vulnerability (MS01-020) in Microsoft Internet Explorer (ver 5.01 or 5.5 without SP2). FIRST AID KIT: AS EMERGENCY MEASURE - Remove, Disable or encrypt all local email addresses (addressbook etc) TO PREVENT FROM SPREADING (BEFORE YOU ARE INFECTED) INCOMING EMAILS: Filter on attachment length 50,688 bytes (UPXed) or 50,664 bytes Filter out attachments, especially .pif, .scr (By the way, you should filter out all attachments anyway) Nail down your Network shares - it replicates itself through them. Make sure all USER PC's have IE updated with latest security patches It takes advantage of a known vulnerability in Microsoft's Internet Explorer versions 5.01 and 5.5 that allows attackers to embed malicious code in the header of an improperly formatted HTML message that could cause e-mail clients such as Outlook to automatically launch attached executable files. Microsoft addressed the issue in Service Bulletin MS01-020 and issued a patch for the vulnerability in March of 2001. Trojan: Port 36974 open - CHECK ON THIS PORT!!!!

The Trojan sends this encrypted file and the IP address of the compromised computer to email addresses that are defined by the hacker. The following is a description of a specific PWS.Hooker.Trojan variant that can be dropped by the W32.Badtrans.gen(a)mm worm. When the Trojan runs, it does the following: It copies itself as C:\%System%\Kern32.exe. NOTE: %System% is a variable. The Trojan locates the \Windows\System folder (by default this is C:\Windows\System or C:\Winnt\System32) and copies itself to that location. It also drops C:\%System%\Hksdll.dll. This file is a component of, and is detected as W32.Badtrans.gen(a)mm. The Trojan adds the value kernel32 C:\%System%\kern32.exe to the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce This causes the Trojan to run then next time that you start Windows.
