Mitigating the Impacts of Doxing on Critical Infrastructure

CISA has produced an insight designed to help mitigate the impact of doxing: Mitigating the Impacts of Doxing on Critical Infrastructure:
Doxing refers to the internet-based practice of gathering an individual’s personally identifiable information (PII)—or an organization’s sensitive information— from open source or compromised material and publishing it online for malicious purposes. Although doxing can be carried out by anyone with the ability to query and combine publicly available information, it is often attributed to state actors, hacktivists, and extremists.
Doxers compile sensitive information from compromises of personal and professional accounts and a wide range of publicly available data sources to craft invasive profiles of targets, which are then published online with the intent to harm, harass, or intimidate victims.
Like many other businesses, critical infrastructure organizations maintain digital databases of PII and organizationally sensitive information, making them ripe targets for doxing attacks. Threat actors may target critical infrastructure organizations and personnel with doxing attacks as a result of grievances related to organizational activities or policies. Incidents of doxing that target personnel and facilities often serve to harass, intimidate, or inflict financial damages, and can potentially escalate to physical violence.
Doxing also poses a threat to senior leadership of critical infrastructure organizations, who may be targeted due to their elevated position with the organization or stance on a particular issue. Doxing attacks targeting senior leaders often serve as “reputation attacks” and could lead to activities seeking to embarrass, harass, or undermine confidence in an official.
