- The CHRISTMA exec did NOT destroy itself after sending copies. I
- erased several from our users minidisks. Also, I did not have to
- shutdown our system. I just listed all the reader files in the system
- and purged any CHRISTMA exec I found. But, there weren't many - I
- forget exactly how many there were but it was less than a hundred.
- Other sites merely drained their RSCS links (software that delivers
- mail and files to other computers) while they cleaned up. There may
- have been some sites that found it necessary to shutdown but I have
- not heard of any. What really stopped the explosion of files was the
- BITNET sites that installed a trap in RSCS to erase any CHRISTMA file
- sent to it. When installed in a few strategic nodes, this trap is
- very effective at stopping this type of trojan horse. Two more
- attempts at distributing CHRISTMA were stopped as well as a couple of
- others whose names I forget. The defense is good enough that most
- people aren't aware of the subsequent attacks. I haven't seen any
- attempts to distribute such trojans in a couple years.
