snydeq writes "A new breed of 'spear phishing' aimed at IT admins
is making the rounds. The emails, containing no obvious malicious
links, are fooling even the savviest of users into opening up holes in
their company's network defenses. The authentic-looking emails, which
often include the admin's complete name or refer to a real project they
are working on, are the product of tactical research or database hacks
and appear as if having been sent by the company's hosting provider.
'In each case, the victim remembered getting a similar sort of email
message when they first signed on with a service and, thus, thought the
bogus message was legitimate — especially because their cloud/hosting
providers keep bragging about all the new data centers they're
continuing to bring online.' The phishing messages often include
instructions for opening up mail servers to enable spam relaying, to
disable their host-based firewalls, and to open up unprotected network
shares. Certainly fodder for some bone-headed mistakes on the part of admins,
the new attack 'makes the old days of hoax messages that caused users
to delete legitimate operating system files seem relatively harmless.'"
