(*): ISC rating
  • We use 4 levels:
    • PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
    • Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
    • Important: Things where more testing and other measures can help.
    • Less Urgent: Typically we expect the impact if left unpatched to be not that big a deal in the short term. Do not forget them however.
  • The difference between the client and server rating is based on how you use the affected machine. We take into account the typical client and server deployment in the usage of the machine and the common measures people typically have in place already. Measures we presume are simple best practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
  • The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threat for affected systems. The rating does not account for the number of affected systems there are. It is for an affected system in a typical worst-case role.
  • Only the organization itself is in a position to do a full risk analysis involving the presence (or lack of) affected systems, the actually implemented measures, the impact on their operation and the value of the assets involved.
  • All patches released by a vendor are important enough to have a close look if you use the affected systems. There is little incentive for vendors to publicize patches that do not have some form of risk to them.
(**)Further clarification from the more generic text above: Windows XP is used in a server role (like it or not), just as Windows 2003 server is used on laptops. The difference between client and server is not how the OS is marketed, not even what it is best suited for, but how its users are using it.

AOL's IM clients are getting attention from the security researchers: following ".." while deposing a file and/or not displaying the same filename as the actually used filename.
  • ICQ: should have updated itself by now, if not, make sure it did.
  • AIM: make sure to upgrade to the latest greatest

Pump and Dump spams are part of a financial fraud scheme. . Aside of the usual spam reporting one can also report the practice to the appropriate official contacts.

Due to the global nature of this spam one needs to have a list of which address to report to.

  • SEC wants your stock related spam
  • Forward the spam to enforcement(AT)
  • You get a standardized reply for every report, typically during the next business day
Germany: Bafin
  • poststelle-ffm(AT)
Australia: ASIC (oversight) and ASX (stock exchange)
  • ASIC has a form, way too impractical for dealing with individual spam messages
  • info(AT)

If you have confirmed and working responsive addresses for other stock exchanges, please let us know.


Thanks to our readers Axel and more for reporting in on this.
