SonicWall Cyber Threat Report – Fileless Malware Spikes in Q3

Fileless malware is a type of malicious software
that exists exclusively as a memory based artifact
(i.e., RAM).

Fileless malware does not write any part of its
activity to the computer’s hard drive, making it
very resistant to existing computer forensic
strategies that incorporate file-based whitelisting,
signature detection, hardware verification,
pattern-analysis, time-stamping, etc.

SonicWall Cyber Threat Report – Ransomware Targets Pt. 2

In Australia, the head of the local intelligence
agency was recruited to inform universities about
cyber threats and ways of prevention. This was
one of the initiatives put in place after an
extremely sophisticated threat actor
compromised the Australian National University

network for months at a time.

SonicWall Cyber Threat Report – Ransomware Targets

In 2019, there was an increase in ransomware
used in targeted attacks toward state, provincial
and local governments, as well as large
corporations.

Attacks have ranged from hospitals, police
stations and educational institutions to
aluminum factories (Norsk Hydro, Norway) and
power grids (City Power, Johannesburg).

“In a modern, citizen-centric environment,
successful ransomware attacks are highly
disruptive,” SonicWall President and CEO Bill
Conner wrote for Forbes.

SonicWall Cyber Threat Report – Momentum of Perimeter-less Security

For decades, protecting networks was entirely focused
on defining perimeters and setting up defense layers to
keep threats out. And for years, this approach served
businesses well, with finite exposure points and attack
vectors that were guarded with some investment and
adherence to established best practices and frameworks.

PDFs, Microsoft Office files among top new file types
In 2019, SonicWall observed that most new threats are
based on malicious PDFs or Office files, followed by Archives.

PDF files are popular because they are searchable, can be viewed on any device, are easy to create and may be encrypted for security, password-protected and/or digitally signed for authentication.
