DYN DDOS Timeline
This morning at 7am ET a DDoS attack was launched at Dyn (the site is still down at the minute), an Internet infrastructure company whose headquarters are in New Hampshire. So far the attack has come in 2 waves, the first at 11.10 UTC and the second at around 16.00 UTC. So far details have been vague, though there are a number of theories starting to surface in the aftermath of the attack. The attack took down numerous websites including Twitter, Amazon, Spotify and Reddit for a period – you can find the full list of affected sites here. PSN and Xbox live apps have also been affected!
The timeline of events according to the DYN updates is as follows:
11:10 UTC- We began monitoring and mitigating a DDoS attack against our Dyn Managed DNS infrastructure. Some customers may experience increased DNS query latency and delayed zone propagation during this time.
12:45 UTC – This attack is mainly impacting US East and is impacting Managed DNS customers in this region. Our Engineers are continuing to work on mitigating this issue.
13:36 UTC – Services have been restored to normal as of 13:20 UTC.
16:06 UTC – As of 15:52 UTC, we have begun monitoring and mitigating a DDoS attack against our Dyn Managed DNS infrastructure. Our Engineers are continuing to work on mitigating this issue.
16:48 UTC – This DDoS attack may also be impacting Dyn Managed DNS advanced services with possible delays in monitoring. Our Engineers are continuing to work on mitigating this issue.
17:53 UTC – Our engineers continue to investigate and mitigate several attacks aimed against the Dyn Managed DNS infrastructure.
18:23 UTC – Dyn Managed DNS advanced service monitoring is currently experiencing issues. Customers may notice incorrect probe alerts on their advanced DNS services. Our engineers continue to monitor and investigate the issue.
18:52 UTC – At this time, the advanced service monitoring issue has been resolved. Our engineers are still investigating and mitigating the attacks on our infrastructure.
20:37 UTC – Our engineers continue to investigate and mitigate several attacks aimed against the Dyn Managed DNS infrastructure.
The attack has come only a few hours after Doug Madory, DYN researcher, presented a talk (you can watch it here) on DDoS attacks in Dallas at a meeting of the North American Network Operators Group (NANOG). Krebs on Security has also drawn links between reports of extortion threats posted on this thread, with the threats clearly referencing DDoS attacks – “If you will not pay in time, DDoS attack will start, your web-services will go down permanently. After that, price to stop will be increased to 5 BTC with further increment of 5 BTC for every day of attack.”
They do however, distance themselves from making any actual claims of extortion, “Let me be clear: I have no data to indicate that the attack on Dyn is related to extortion, to Mirai or to any of the companies or individuals Madory referenced in his talk this week in Dallas”
However, this isn’t the only theory circulating at the moment. Dillon Townsel from IBM security has tweeted:
Heavy.com has reported that hacking group PoodleCorp are being blamed for the attack by Product-reviews.net because of the cryptic tweet that they posted 2 days ago, “October 21st #PoodleCorp will be putting @Battlefield in the oven”
PoodleCorp famously took down the Pokemon Go servers in July. Homeland Security and the FBI are investigating the attack and are yet to deem who was responsible.
Today’s attack is very different to the DDoS style that Anonymous rose to fame with. Instead of attacking and taking out an individual website for short periods of time, hackers took down a massive piece of the internet backbone for an entire morning, not once but twice with new reports of a potential 3rd wave. At the moment there have been no claims of ownership for the attack nor has there been any concrete evidence of who perpetrated the attack.
Dyn are well known for publishing detailed reports on attacks of this nature so we can only hope they will do the same for their own servers.
Until then you can follow any updates that Dyn are releasing here.
(Update: Report of Wikileaks supporters involvement in the DDoS, but nothing definitive at the moment as to which supporting group. Until then we will wait and see…)
