Cybercrime tactics and techniques Q1 2019

Enterprises, beware. Threat actors are continuing to eye businesses for high returns on investment in Q1 2019, breaching infrastructure, exfiltrating or holding data hostage, and abusing weak credentials for continued, targeted monitoring. From a steadfast increase of pervasive Trojans, such as Emotet, to a resurgence of ransomware lodged against corporate targets, cybercriminals are going after organizations with a vengeance.

Yet every cloud has a silver lining, and for all the additional effort thrown at businesses, consumer threats are now on the decline. Ransomware against consumers has slowed down to a trickle and cryptomining, at a fever pitch against consumers this time last year, has all but died. Interestingly, this has resulted in an overall decline in the volume of malware detections from Q4 2018 to Q1 2019.

So how did we draw our conclusions for this report? As we’ve done for the last several quarterly reports, we combined intel and statistics gathered from January 1 through March 31, 2019, from our Intelligence, Research, and Data Science teams with telemetry from both our consumer and business products on the PC, Mac, and mobile devices, which are deployed on millions of machines. Here’s what we learned about cybercrime in the first quarter of 2019.
