Email Hacks South Africa: Business Email Compromise BEC.

Business Email Compromise BEC What to do:

If in doubt delete. Zero Trust Policy.

Users to be trained in security best practices and simulations like not to open attachments before verifying.
Ensure the domain visible in the received email is associated with the business it was emailed from.
Make sure the address to:field section in the email client email matches your email address.
Do not open if the senders and to:field emails are the same.
Do not open emails with attachments and invoices addressed to undisclosed recipients.
Do not follow drive links, like Google Drive or Dropbox links, to download invoices or other content from unrecognized, undisclosed recipients or non-first-tier friend contacts.
Be aware of colleagues or clients informing you of mysterious emails coming from your accounts.
Turn off links and images in the email client. If in doubt drop the email in the junk mail to check links.
Link hover, use the mouse and hover over the links in the email to check if they match the sender’s domain.
Latest patches and updates to all software. Most attacks are not detectable by anti-virus software at the home user level nor at the Corporate level.
Do not list the accounting or admin emails online. Use a generic info@ for websites and social media.
Question all marked as urgent payment emails and unplanned payment instructions as suspicious. Contact, preferably face to face, the co-worker or line manager that issued the directive. Social engineering exploits our compliance when issued with a directive from an authority figure. Any changes to Beneficiary Banking details must be verified if possible, using traditional methods or original contact details. If in doubt check with your line manager.
