Protecting Cryptocurrency from Threats

Protecting Cryptocurrency from Threats

As of March 2018 there were more than 1,000 cryptocurrencies in circulation, with a total value of over $400 billion – up from $19 billion just a year earlier. While the underlying blockchain technology of the cryptocurrency is in most cases natively secure, with this rapidly growing adoption it is important to examine where the cryptocurrency is vulnerable and how the various players of the ecosystem can secure their investments.

Q4 2017 Global DDoS Threat Landscape

Q4 2017 Global DDoS Threat Landscape

In Q4 2017, the bitcoin industry continued to draw significant attack traffic, this time making it onto the most attacked industry list according to number of attacks and number of targets. While there was a drop in the number of network layer attacks this quarter, which fell by 50 percent, application layer assaults nearly doubled. At the same time, there was a spike in both network and application attack persistence.

Q3 2017 Global DDoS Threat Landscape

In Q3 2017, amidst a cryptocurrency price spike, bitcoin came in as one of the top-10 most attacked industries. There was also a notable increase in network layer attack persistence, with nearly a third of targets being hit ten or more time. Lastly, we saw high packet rate attacks grow more common this quarter, as an alarming number of assaults escalated over 100 Mpps.

Q2 2017 Global DDoS Threat Landscape

Q2 2017 Global DDoS Threat Landscape

In Q2 2017, for the fifth time in a row, we saw a decrease in the number of network layer assaults and an increase in the frequency of repeat application layer attacks. Q2 2017 also saw the emergence of a new attack tactic, which we nicknamed “pulse wave DDoS” due to the traffic pattern it generates—a rapid succession of attack bursts that split a botnet’s attack output.

Understanding Pulse Wave DDoS Attacks

Understanding Pulse Wave DDoS Attacks

Comprised of a series of short-lived bursts occurring in clockwork-like succession, pulse wave assaults accounted for some of the most ferocious DDoS attacks Imperva Incapsula has ever mitigated. This paper explains the nature of these attacks, how they are used and which soft spots they look to exploit.

Q1 2017 Global DDoS Threat Landscape

Q1 2017 Global DDoS Threat Landscape

In Q1 2017, the number of network layer assaults decreased for the fourth quarter in a row, while the number of application layer attacks hit an all-time high. This quarter was notable, both for the spike in repeat assaults and the uptick in multi-vector attacks, which accounted for 40.5 percent of all network layer DDoS attacks.

Q4 2016 Global DDoS Threat Landscape

Q4 2016 Global DDoS Threat Landscape

Driven by the emergence of powerful IoT botnets and the declining cost of DDoS-for-hire services, DDoS attacks in Q4 2016 continued to escalate in size and persistence. This trend was highlighted by a massive 650Gbps network layer assault – the largest ever mitigated by our service. Discover the latest developments in network and application layer attacks as well as new hubs of botnet activity in this report.

Q3 2016 Global DDoS Threat Landscape

Q3 2016 Global DDoS Threat Landscape

In Q3 2016, application layer DDoS attacks reached record-breaking numbers across several metrics including size, number and frequency of attacks. The number of application layer assaults increased 22.6 percent over Q2, while a record-high 11.6 percent of websites were targeted more than 10 times. Attack data also highlighted the widespread use of botnet-for-hire services (aka booters and stressers). Learn more about the latest DDoS trends and botnet activity in this report.
