A new report released on Tuesday by the email analytics platform 250ok found that more global law firms are adopting domain-based message authentication, reporting and conformance, or DMARC, solutions designed to help authenticate emails and protect against spoofing. The report analyzed 100 parent domains belonging to the top 100 accredited law firms internationally.

The rising popularity of DMARC tools could be attributable to the evolution of spear-phishing attacks, which more often places a heavier emphasis on strategically selecting targets with lucrative relationships to exploit rather than relying on widespread and haphazard email campaigns.
