On January 30th, Peek, Inc (getpeek.com), providers of the Peek9 mobile email device, similar to a Blackberry, terminated service to all clients with no warning, possibly as a result of being hacked. (Their website was redirected to a Russian porn (?) forum.)
On Wednesday, they sent users the following email:
Dear Peek user,
Since we launched Peek in September 2008, we received amazing accolades for the
product and the support of many, many Peeksters like you.
Since 2010 the business has been taking off in a direction that moved us away from
these devices -- putting our cloud platform and software to work bringing smart apps
to simple devices made by other mobile phone makers.
We have been winding down the US service since late 2010, and at the end of 2011
this email address was connected to one of a few Peek devices still operating in the
US. At the end of January, this last batch of devices was decommissioned.
This was the first hint that they were "winding down" anything, and devices and service were still being sold on their website roughly one week ago.
As of this morning, February 3rd, their servers at Amazon continue to poll mailboxes formerly associated with the service.
I'd recommend all hosts check their mail logs for POP3 access from:
...and check any affected user accounts for suspicious activity.
I do not believe they are being honest about their reason for ceasing business, but in any event, with the termination of their service, I consider ongoing access from their servers (which may no longer be under their control) unauthorized, suspicious, and a security risk.
