Since last year, a growing number of reports targeting high ranking officials from small to medium businesses have been recorded linking to Perswaysion hacking attack. Executive Monitoring did by a group of cyber researcher name Group-IB confirmed at least 156 officials from the US, Germany, the UK, Netherlands, Hong Kong, and Singapore had their email accounts been compromised of this hideous act.

As a 3-layered email phishing scam, targeted officials are being sent an email with a file-sharing attachment that once open, will redirect them to the phishing site where they need to fill up information to initiate the sharing.

However, they warned that to only use this resolution if they highly suspect that they are infected as this will ask for sensitive information of the user.
