ELF_SSHSCAN.A and ELF_PORTSCAN.A

Found two files, elf_sshscan.a and elf_portscan.a, compressed in a *.tgz 
file on a Red Hat box.  Exported the file to a MS box, Trend Micro 
OfficeSacn detected them as viruses, but did not provide any information 
other than the names in its knowledgebase.

Searched TM site, no information was available today.

Any information of these two viruses, such as how the virus getting on to 
the Red Hat box, etc. are appreciated.

Thanks,
