DDoS attack tool timeline
May/June, 1998
First primitive DDoS tools developed in the underground -- small
networks, only mildly worse than coordinated point-to-point DoS attacks
July 22, 1999 CERT
releases Incident Note 99-04 mentioning widespread intrusions on Solaris RPC
services
August 5, 1999
First evidence seen at the UW of programs being installed on Solaris
systems in what appeared to be "mass" intrusions.
August 17, 1999
Attack on the University of Minnesota reported to UW network operations
and security teams.
September 2, 1999
Contents of a stolen account used to cache files was recovered
September 27, 1999
CERT provided with first draft of trinoo analysis
Early October 1999
CERT goes through the painful process of reviewing hundreds of Solaris
intrusion reports and finds many match the trinoo analysis. They arrange the
Distributed System Intruder Tools Workshop (the first time they have done
this.)
October 15, 1999
CERT mails out invitations to the DSIT workshop.
October 23, 1999
Final draft of trinoo analysis and TFN analysis finished in preparation
for the DSIT workshop.
November 2-4, 1999
DSIT workshop held in Pittsburgh. It is agreed by attendees that it is
important to not panic people, but instead provide meaningful steps to deal
with this new threat. All attendees are asked to keep information about DDoS
programs private until we all finish a report on how to respond.
November 18, 1999
CERT releases Incident Note 99-07 mentioning DDoS tools. Work is still
continuing on DSIT Workshop report.
November 29, 1999
SANS NewsBytes Vol. 1 Num. 35 mentions trinoo/TFN in the context of
widespread Solaris intrusion reports they were getting that were consistent
with CERT IN-99-07 and involving ICMP_ECHOREPLY packets.
December 7, 1999
ISS releases an advisory on trinoo/TFN after first non-technical mention
of DDoS tools in a USA Today article. CERT rushes out the final report of the
DSIT workshop. I publish my analyses of trinoo and TFN to the BUGTRAQ email
list.
December 8, 1999
(According to USA Today article) NIPC sends a note briefing FBI Director
Louis Freeh for the first time.
December 17, 1999
(According to USA Today article) NIPC director Michael Vatis briefs
Attorney General Janet Reno as part of an overview of preparations being made
for Y2K
December 27, 1999
As final work on analysis of "stacheldraht", a scan of the UW
network was made with "gag" (included in the stacheldraht analysis),
which found three active agents which were traced to a handler in the southern
US. The ISP and their upstream provider were able to identify over 100 agents
in this network.
December 28, 1999
CERT releases Advisory 99-17 on Denial-of-Service Tools (covers TFN2K
and MacOS 9 DoS exploit).
December 30, 1999 I
publish my analysis of stacheldraht to the BUGTRAQ email list. NIPC issues a
press release on DDoS programs and releases Distributed Denial of Service Attack
Information (TRINOO/Tribal Flood Net) (including a tool for scanning local file
systems/memory for DDoS programs.)
January 3, 2000
CERT and FedCIRC jointly publish Advisory 2000-01 on Denial-of-Service
Developments. Discusses stacheldraht and NIPC scanning tool.
January 4, 2000
SANS asks its membership to use published DDoS detection tools to
determine how widely these tools are being used. Reports of successful searches
start coming in within hours.
January 5, 2000 Sun
releases bulletin #00193, "Distributed Denial-of-Service Tools"
January 14, 2000
Attack on OZ.net in Seattle affects Semaphore and UUNET customers
(affecting as much as 70% of Puget Sound Internet users, and possibly other
sites in the US -- no national press attention until January 18.)
January 17, 2000
ICSA.net organizes Birds of a Feather (BOF) session on Distributed
Denial of Service attacks at RSA 2000 conference in San Jose.
February 7, 2000
Talk by Steve Bellovin on Denial of Service attacks, and another ICSA.net
DDoS BOF at NANOG meeting in San Jose. First attacks on eCommerce sites begin.
February 8 - 12, 2000
Attacks on eCommerce sites continue. Media feeding frenzy begins...
Important (in my opinion) points about the timeline
-Technical details of the developing DDoS tools was not
available to federal agencies until late
September and early October.
-It took CERT time to review a large set of intrusions and
determine the best way to respond (without causing a panic reaction by the
general public.)
-CERT announced the DDoS tools in mid November 1999, and
shortly after published an Incident Note and Advisory. Any sites paying
attention to CERT Incident Notes and Advisories learned of trinoo, TFN, and
TFN2K in November and December.
-Anyone reading BUGTRAQ learned of trinoo and TFN on
December 7, 1999 and stacheldraht on December 30, 1999.
-NIPC's advisory and tool came out just after the technical
analyses were published, but because all three commonly used DDoS tools were
discussed publically by late December it seems to me to be overly critical to
say the government "failed" to warn eCommerce sites before February
7, 2000. They could have learned about them from CERT's Incident Note, DSIT
Workshop Report, and postings to BUGTRAQ in November and December.
