When investigating people connected to companies, @BelarusFiles' Alina Yanchur, recommends looking at other business records in an individual’s name — to find, for example, phone numbers — as well as using @OCCRP's @alephdata & the OSINT.industries. buff.ly/4belh0t

Very cool analysis linking up company ownership, procurement contracts and our extended sanctions lists to find where supporters of the Russian dictatorship benefit from EU budget monies.
Despite sanctions, firms with Russian influence keep winning public tenders in the EU. We show that public institutions might have difficulties in following the sanction rules. datlab.eu/blog/mapping-russi…

Enormously excited about this: we're weaving a tapestry of compliance open data by linking from sanctioned companies to their @opencorporates profiles.
Our company identifiers are now in @open_sanctions so you can explore more detail about sanctioned entities more easily – a win for the open data ecosystem. Find out more bit.ly/3AZjQV8
