New Mobile Malware Spotted in the Wild, Hundreds of Users Affected

We’ve recently, intercepted, a
currently, circulating, malicious, spam, campaign, affecting,
hundreds, of users, globally, potentially, exposing, the,
confidentiality, availability, and, integrity, of, their, devices,
to, a, multi-tude, of, malicious, software. Largely, relying, on, a,
multi-tude, of social engineering, vectors, the, cybercriminals,
behind, the, campaign, have, managed, to, successfully, impersonate,
Adobe Flash Player, users, into, thinking, that, they’re, visiting,
a, legitimate, Web
site, on, their, way, to, infect,
their, devices, relying, on, bogus “Please update Flash on
your device
“, messages.
Over, the, last, couple, of, years,
we’ve, been, monitoring, an, increase, in rogue Google Play, type,
of, Android, applications, capable, rogue online Web sites, tricking,
tens, of, thousands, of, users, on, a, daily, basis, into,
installation, rogue, applications, largely, relying, on, a,
multi-tude, of, social engineering, vectors. Next, to, rogue, online,
Web, sites, we’ve, been, also, actively, monitoring, an, increase,
in, compromised, Web sites, serving, malicious, software,
potentially, exposing, the, confidentiality, availability, and,
integrity, of, their, devices, to, a, multi-tude, of, malicious,
software. We’ve, been, also, busy, monitoring, an, increase, in,
ongoing, monetizing, of, hijacked, traffic, type, of, underground,
market, traffic, exchanges, with, more, cybercriminals, successfully,
monetizing, the, hijacked, traffic, while, earning, fraudulent,
revenue, in the, process.
In, this, post, we’ll, profile, the,
malicious, campaign, provide, actionable, intelligence, on, the,
infrastructure, behind, it, and, discuss, in-depth, the, tactics,
techniques, and, procedures, of, the, cybercriminals, behind, it.
