warns that ransomware operators are targeting at least 1,800 large
organizations worldwide in industries such as construction, chemical, healthcare,
food, entertainment and critical infrastructure (energy, water, utilities).

The report
says three ransomware strains are used in attacks worldwide, including many
targeting the Netherlands. Those are LockerGoga, MegaCortex and Ryuk, which have
gained notoriety over the past year in attacks on large infrastructures with
high annual turnover rates.

The NCSC said
it has only identified 1,800 victims, but the actual number of targeted
organizations could be much higher.

branches of multinationals have also been hit, including those of an American

to infect these kinds of infrastructures.
