Report: Beazley breach insights - January 2017
Ransomware attacks soar in 2016, projected to double again 2017.
Ransomware attacks handled by Beazley more than quadrupled in 2016, with nearly half of these attacks in the healthcare sector, and Beazley projects these attacks will double again in 2017. Organizations appear to be particularly vulnerable to attacks during IT system freezes, at the end of financial quarters and during busy shopping periods. Evolving ransomware variants enable hackers to methodically investigate a company's system, selectively lock the most critical files, and demand higher ransoms to get the more valuable files unencrypted.
The rise of unintended disclosure as a breach cause indicates that formerly small mistakes now have the potential to quickly lead to large data breaches. Employee education and training, up to date IT system protections and an incident response plan for when a breach occurs continue to be the best defenses against these attacks.
