  13. Afternoon Everyone,
  14.  
  15. As you can guess from the subject line, I've not had what many would
  16. consider a "good" day.  Earlier today discovered a trojan existing on
  17. HPA's personal colo machine, as well as hera.  Upon some investigation
  18. there are a couple of kernel.org boxes, specifically hera and odin1,
  19. with potential pre-cursors on demeter2, zeus1 and zeus2, that have been
  20. hit by this.
  21.  
  22. As it stands right now, HPA is working on cleaning his box, and
  23. I'm working on hera (odin1 and zeus1 are out of rotation still for other
  24. reasons), mainly so that if one of us finds something of interest, we
  25. can deal with it and compare notes on the other box.
  26.  
  27. Points of interest:
  28.  
  29. - - Break-in seems to have initially occurred no later than August 12th
  30.  
  31. - - Files belonging to ssh (openssh, openssh-server and openssh-clients)
  32. were modified and running live.  These have been uninstalled and
  33. removed, all processes were killed and known good copies were
  34. reinstalled.  That said all users may wish to consider taking this
  35. opportunity to change their passwords and update ssh keys (particularly
  36. if you had an ssh private key on hera).  This seems to have occurred on
  37. or around August 19th.
  38.  
  39. - - A trojan startup file was added to rc3.d
  40.  
  41. - - User interactions were logged, as well as some exploit code.  We have
  42. retained this for now.
  43.  
  44. - - Trojan initially discovered due to the Xnest /dev/mem error message
  45. w/o Xnest installed; have been seen on other systems.  It is unclear if
  46. systems that exhibit this message are susceptible, compromised or not.
  47. If you see this, and you don't have Xnest installed, please investigate.
  48.  
  49. - - It *appears* that 3.1-rc2 might have blocked the exploit injector, we
  50. don't know if this is intentional or a side affect of another bugfix or
  51. change.
  52.  
  53. - - System is being verified from backups, signatures, etc.  As of right
  54. now things look correct, however we may take the system down soon to do
  55. a full reinstall and for more invasive checking.
  56.  
  57. - - As a precaution a number of packages have been removed from the
  58. system, if something was removed that you were using please let us know
  59. so we can put it back.
  60.  
  61. - - At this time we do not know the vector that was used to get into the
  62. systems, but the attackers had gained root access level privileges.
  63.  
  64. That's what we know right now, some of the recent instabilities may have
  65. been caused by these intrusions, and we are looking into everything.
  66.  
  67. If you are on the box, keep an eye out, and if you see something please
  68. let us know immediately.
  69.  
  70. Beyond that, verify your git trees and make sure things are correct.
  71.
