DDoS Attacks Jump 542% from Q4 2019 to Q1 2020

The shift to remote work and heavy reliance on online services has driven an increase in attacks intended to overwhelm ISPs.

In the first quarter of 2020, distributed denial-of-service (DDoS) attacks jumped more than 542% compared with the last quarter of 2019 and more than 278% year-over-year. NexusGuard researchers suggest the spike may be linked to a parallel increase in malicious cyber activity during the COVID-19 pandemic.

Cybercriminals have responded to the work-from-home shift with a series of long DDoS attacks aimed at hosting providers and businesses. The Akamai team recently mitigated the largest packet-per-second DDoS attack recorded on the company's platform — double the volume of its previous record. Researchers see attackers shifting toward attacks with lower bits-per-second and higher packets-per-second, likely seeking weak spots in DDoS mitigation techniques.

In addition to traditional DDoS attacks, NexusGuard researchers detected abnormal traffic patterns from ISPs such as traffic generated from infected devices, and traffic generated by exploiting open resolvers (DNS, DLAP, etc.) to create small, short attacks they call "invisible killers." ISPs often overlook these threats, the researchers explain in a new DDoS threat report. 

Data shows 67% of DDoS attacks fall in the size range of 1 Gbit/s and 5 Gbit/s. These typically are shorter than 15 minutes and create fewer than 200 events per day. Because these attacks are smaller and are overlooked compared with overall traffic, it normalizes the traffic activity and gives the "invisible killer" access to networks of websites and online services to cause damage. 

NexusGuard found these "bits-and-pieces attacks" result from slowly bringing doses of junk traffic into a large IP pool, which can clog the target system when pieces start to accumulate from different IPs. Ninety percent of attacks used a single-vector approach, a shift from the multivector attacks commonly used in the past.

Re: Ease of Execution
Very much agreed. It just amazes me to what degree people are willing to go.

COVID
NexusGuard researchers suggest the spike may be linked to a parallel increase in malicious cyber activity during the COVID-19 pandemic. Obviously COVID had more impact in our lives more than we could even imagine.

DNS
traffic generated by exploiting open resolvers (DNS, DLAP, etc.) to create small, short attacks they call "invisible killers." ISPs often overlook these threats, the researchers explain in a new DDoS threat report. This makes sense. It is not that difficult to flood DNS for forward and reverse lookups.

Re: Ease of Execution
The reason being its ease of execution and for the past few years it has even been sold as a service for relatively cheap. It really makes sense. DDoS is always possible as long as you can do it with mass scale you would have great impact.

Re: Ease of Execution
For a few years now we've started to DDoS attacks occur even in as something as trivial as taking down a persons service while playing a video game. Agree. If you repeat that to good number of cases than they achieve Daniel of service.

DDoS?
In the first quarter of 2020, distributed denial-of-service (DDoS) attacks jumped more than 542% compared with the last quarter of 2019 and more than 278% year-over-year This makes sense, most of us are working from home and home technology more.

Ease of Execution
Considering the ease of execution I would think this trend will continue. For a few years now we've started to DDoS attacks occur even in as something as trivial as taking down a persons service while playing a video game.

The reason being its ease of execution and for the past few years it has even been sold as a service for relatively cheap.

CVE-2020-27348
PUBLISHED: 2020-12-04
In some conditions, a snap package built by snapcraft includes the current directory in LD_LIBRARY_PATH, allowing a malicious snap to gain code execution within the context of another snap if both plug the home interface or similar. This issue affects snapcraft versions prior to 4.4.4, prior to 2.43...
CVE-2020-16123
PUBLISHED: 2020-12-04
An Ubuntu-specific patch in PulseAudio created a race condition where the snap policy module would fail to identify a client connection from a snap as coming from a snap if SCM_CREDENTIALS were missing, allowing the snap to connect to PulseAudio without proper confinement. This could be exploited by...
