Q2 2015

malicious activity key trends

• In both Q1 and Q2 of 2015, the number of DDoS
  attacks recorded hit a new record
• For the last three quarters, year-over-year
  DDoS activity has doubled
• Since Q2 of 2014, the profile of the typical
  attack has shifted from high-bandwidth,
  short-duration attacks to less powerful, longer
  duration attacks
• Mega attacks are getting larger and more
  frequent
• The largest attack measured 249 Gbps
• Five attacks in Q2 2015 peaked at over 50 Mpps
• SYN and Simple Service Discovery Protocol
  (SSDP) were the most common attack vectors
• Though infrastructure attacks are most common,
  application layer DDoS attacks continue to grow
  rapidly

• Dramatic increase in DDoS attack frequency
• Compared to Q2 2014, a 132 increase in total
  DDoS attacks
• Longer, less powerful attacks persist
• Average peak volume of attacks decreased by 77
  percent compared to Q2 2014
• Average peak bandwidth decreased 11
• Average attack duration increased 19
• Mega attacks double year-over-year

DDoS attack makeup

• Infrastructure-layer attacks dominated DDoS
  methodologies, accounting for 90 of all recorded
  attacks
• SYN floods were the most common attack vector,
  at 16 of all DDoS Attacks
• SYN floods played a significant role in mega
  attacks
• Largely due to the rise of SSDP attacks, the
  percentage of SYN floods has declined since Q2
  2014, when it was 26
• SSDP attacks were just under 16 of total DDoS
  attacks
• Slight decline from Q1 2015, when SSDP attacks
  were 21 of total
• SSDP attacks are more difficult to mitigate
  because they often use unsecured, home-based
  Internet devices
• Most-common application-layer attack was HTTP
  GET , accounting for 7.5 of DDoS activity,
  consistent with Q1 2015 and Q4 2014 observations

mega attacks in Q2 2015

• In Q2 2015, 12 DDoS attacks registered more
  than 100 Gbps
• The largest attack measured 249 Gbps, a
  significant increase from the largest (170 Gbps)
  attack of Q1 2015
• Gaming sites were the primary target of the
  attacks
• Two of 12 mega attacks target gaming sites
  directly
• The 10 attacks recorded against Internet and
  telecom were actually targeting gaming sites
  hosted on the customer network
• 50 Mpps attacks threatened significant damage
  in Q2
• Attacks of this volume can exhaust ternary
  content addressable memory (TCAM) resources and
  take out tier 1 routers, such as those used by
  Internet service providers (ISPs)
• A 214 Mpps attack on June 12 was one of the
  three largest DDoS attacks ever recorded across
  the Prolexic Routed network
• Attack was based on a UDP flood with 1-byte
  packets
• Generated 70 Gbps of attack traffic

targeted industries

• Gaming has been the most targeted industry since
  Q2 2014
• Online gaming networks suffered 35 of DDoS
  attacks, as in Q1 2015
• Software and Technology, including
  Software-as-a-Service and cloud-based
  technologies, was the second most common target
• Suffered 28 of attacks, a slight increase of 2
  from Q1 2015
• Internet and Telecoms suffered 13
• Slight decrease of 1 from last quarter
• Media and Entertainment surpassed Financial
  Services
• Attacks on media and entertainment businesses
  increased by 2 percent.

source countries

• China remained the leading source of
  non-spoofed DDoS attack traffic
• Accounted for 37 of DDoS traffic, up from 23
  last quarter
• US rose to second place
• 18 of recorded DDoS traffic originated from the
  US
• A shift from Q2 2014, when the US was the number
  one source at 20
• UK was the third most common source country
• Accounted 10 of DDoS traffic
• In Q2 2014, the UK was not in the top 10
• Decreases in percentages do not represent a
  drop in DDoS traffic from these countries
• DDoS traffic sources have increasingly
  diversified other countries are producing more
  DDoS traffic, rather than the US producing less
