Beware of strange requests from an 'acquaintance'
Sometimes hackers try to impersonate an acquaintance (e.g. a colleague), asking the addressee to share certain information. This is a form of social engineering.
A typical example of this is a request to make emergency payments or buy gift cards for someone who is unable to do so themselves.
When in doubt, always contact the person in question (preferably by telephone) to verify that the request is indeed from that person. And if you are asked for (confidential) information, always consider whether you are allowed/able to give it. If in doubt: don't do it!
