Targeted Attacks on the Rise; Companies Must Be on the Defensive

Posted on 6.25.2015

Vectra Networks, a real-time website security firm, has announced the results of its second edition Post-Intrusion Report, which details threats to evade perimeter defenses and what attackers do once they get in a network.

Collecting data over six months form 40 current and prospective customers, the report includes trends in malware behavior, attacker communication techniques, data exfiltration and more. According to the report, there was a 97 percent increase in overall detections when compared to the previous year as well as a 1000 percent jump in Tor detections when compared to the previous year. Furthermore, ad click fraud was the most commonly observed botnet monetization behavior, representing 85 percent of all botnet detections.

Other findings from the study include an increase in lateral movement (580 percent) and reconnaissance detections (270 percent) when compared to the year prior.

“The increase in lateral movement and reconnaissance detections shows that attempts at pulling off targeted attacks continue to be on the rise," said Oliver Tavakoli, Vectra Networks CTO. "The attackers' batting average hasn't changed much, but more at-bats invariably has translated into more hits."
