On the malware front, the summer of 2019 was quiet and steady-state. But the end of Q3 saw the infamous Emotet resurface, presaging a malware uptick in Q4. Read all about it in the Cofense Q3 2019 Malware Trends Report.
Maintaining a relative lull when Emotet suspended activity, threat actors in Q3 stuck to tried-and-true practices of intrusion. Phishing emails containing keyloggers (namely ‘Agent Tesla’) slightly rose in popularity, while information stealers like Loki Bot fell. Threat actors continue to seek the easiest, most efficient way of infiltrating users. Agent Tesla, for example, offers customer support and a web interface to develop and manage the keylogger. Similarly, cybercriminals continue to capitalize on known and patched vulnerabilities to deliver malware through phishing campaigns.
When Emotet resurfaced towards the end of Q3, this significant malware player wasted no time in compromising email chains or tricking users with convincing templates. As such, CofenseTM expects Q4 to show more malware activity.
