According to the infographic above:
- IoT attack volume increase
In 2019, SonicWall discovered a 5% increase in IoT malware, with total volume reaching 34.3 million attacks. But with a deluge of new IoT devices connecting each day, increases in IoT malware attacks should not only be expected, but planned for.
- malware attacks although decreased, they became more targeted and evasive.
SonicWall reported of 9.9 billion malware attacks in 2019, meaning a 6% declines, in comparison to the 10.52 million attacks reported in 2018.
- ransomware found a new target
Now, ransomware is being used to surgically target victims that are more likely to pay given the sensitive data they possess or funds at their disposal (or both).
In 2019, this meant that many of the 187.9 million ransomware attacks were against state, provincial and local governments, as well as education systems.
- cryptojacking crumbles
The price of bitcoin and complementary cryptocurrencies created an untenable situation between Coinhive-based cryptojacking malware and the legitimate Coinhive mining service.
After the shuttering of Coinhive, the volume of cryptojacking hits dropped 78% during the second half of 2019.
- fileless malware peaks in Q3 2019
Fileless malware exists exclusively as a memory-based artifact and does not write any part of its malicious activity to the computer's hard drive, making it very resistant to forensic strategies. Volume peaked in the third quarter, with more than 570,000 attacks recorded by SonicWall in September 2019 alone.
- encrypted threats rise
Savvy cybercriminals continue to use TLS/SSL encryption to mask their attacks from inspection by traditional security controls. In 2019, SonicWall Capture Labs threat researchers recorded a 27.3% year-over-year increase of malware sent over TLS/SSL traffic.
