For several months I’ve been poking at a decent-sized spam botnet that appears to be used mainly for promoting adult dating sites. Having hit a wall in my research, I decided it might be good to publish what I’ve unearthed so far to see if this dovetails with any other research out there. In late October 2016, an anonymous source shared with KrebsOnSecurity.com a list of nearly 100 URLs that — when loaded into a Firefox browser — each displayed what appeared to be a crude but otherwise effective “counter” designed to report in real time how many “bots” were reporting in for duty. Here’s a set of archived screenshots of those counters illustrating how these various botnet controllers keep a running tab of how many “activebots” — hacked servers set up to relay spam — are sitting idly by and waiting for instructions.

Researchers have created a device using off-the-shelf components that can sniff out controversial cell phone surveillance devices, known as IMSI-catchers or StingRays, used by federal and state law enforcement as well as hackers.

The International Mobile Subscriber Identity-catchers have not only been used to locate mobile devices but also to sometimes eavesdrop on users, send spam or upload malware, according to University of Washington (UW) security researchers.

“The threats remain the same when looking at enterprises: tracking and, under certain circumstances, eavesdropping are possible through this attack,” said Dionisio Zumerle, a Gartner research director for Mobile Security. “The attack requires technical expertise and equipment that was once hard to find; today it is easier and that is the main source of concern.”
