As the world contends with the COVID-19 pandemic, organizations are being forced to rapidly adapt to novel methods of working. They are grappling with the challenges of working from home and business continuity sites, under highly restricted conditions. In response to the disruption, many companies across the region have enabled remote access solutions, remote collaboration tools, and cloud services. Several are allowing employees to use personal devices and have enabled the use of home networks for an extended period of time.

Some organized crime groups have recognized an opportunity to exploit the seeds of fear and uncertainty sown by COVID-19, and take advantage of the control deficiencies associated with remote working conditions, to target individuals and businesses in a variety of ways. KPMG Lower Gulf identifies key controls across ten risk areas.
