Cybersecurity incident

Zephyr Energy plc (AIM: ZPHR) (OTCQB: ZPHRF) reports that one of its U.S.
subsidiary companies has been targeted in a cybersecurity incident.

 

The highly sophisticated incident involved the diversion of a single payment
to a contractor and resulted in funds of circa £0.7 million being transferred
to a third-party account. Upon discovery of the incident, the Company
immediately notified the relevant law enforcement authorities and is working
with the corresponding banks and consultants to attempt to recover the
diverted funds.

 

The Company's IT systems have been thoroughly assessed by a leading
cybersecurity consultant, the incident is contained, and the Company's
operations and corporate activity are continuing as normal.  The Company's IT
consultants continue to monitor the Company's systems.

 

While Zephyr uses industry standard practices in relation to its technology
and payment systems, additional layers of security have been implemented as a
result of this attack.

 

The Company's board of directors can confirm that the Company has more than
sufficient working capital to ensure that this isolated matter will not impact
the Company's ability to perform its ongoing operations.
