In, a, cybercrime, ecosystem, dominated, by, malicious, software, releases, cybercriminals, continue, actively, populating, their, botnet's, infected, population, further, spreading, malicious, software, potentially, exposing, the, confidentiality, integrity, and, availability, of, the, affected, hosts, further, spreading, malicious, software, while, monetizing, access, to, malware-infected, hosts, largely, relying, on, the, utilization, of, affiliate-based, type, of, monetizing, scheme.

We've, recently, intercepted, a, currently, circulating, malicious, spam, campaign, enticing, users, into, executing, a, malicious, software, largely, relying, on, basic, visual, social, engineering, enticing, users, into, executing, a, rogue, application, potentially, exposing, the, confidentiality, integrity, and, availability, of, the, affected, host.

In, this, post, we'll, profile, the, campaign, provide, actionable, intelligence, on, the, infrastructure, behind, it, and, discuss, in-depth, the, tactics, techniques, and, procedures, of, the, cybercriminals, behind, it.
