Speed is the most effective defense against cyber threats: CrowdStrike survey

Reports offers insight into how fast companies need to be at detecting, investigating and remediating intrusions.

February 21, 2019 / 08:27 PM IST

CrowdStrike, the cloud-delivered endpoint protection company, announced the release of the 2019 CrowdStrike Global Threat Report: Adversary Tradecraft and The Importance of Speed.

Key findings in the report point to the escalating activities of nation-state actors and global eCrime actors across all targeted industries, and offer lessons learned from real-life intrusions.

In today’s ever-evolving cyber landscape, speed is essential for effective cyber defense. CrowdStrike’s Global Threat Report reveals “breakout time” – the critical window between when an intruder compromises the first machine and when they can move laterally to other systems on the network – for top cyber adversaries.

This ranking offers organizations unprecedented insight into how fast they need to be at detecting, investigating and remediating intrusions (also known as the 1-10-60 rule) to thwart adversaries they are most likely to face targeting their networks.

According to CrowdStrike’s visibility, based on more than 30,000 breach attempts stopped in 2018:

  • Russian nation-state actors, tracked by CrowdStrike as “Bears,” are the fastest adversaries with an average breakout time of 18:49 minutes.

  • North Korean nation-state actors, tracked as “Chollimas,” are the second fastest with an average breakout time of 2:20:14 hours.

  • Chinese nation-state actors, or “Pandas,” average 4:00:26 hours.

  • Iranian nation-state actors, or “Kittens,” average 5:09:04 hours.

  • eCrime actors, or “Spiders,” have the slowest average breakout time of all adversaries: 9:42:23 hours, although some of the eCrime actors can move very rapidly and rival even the fastest nation-states.

Dmitri Alperovitch, CrowdStrike’s chief technology officer and co-founder, said, “This year’s report underscores the importance of speed of response in cybersecurity and provides valuable insights into how to defeat some of the most destructive and capable nation-state and eCrime threat actors.”

Notable Highlights of the Global Threat Report:

One of the most significant trends in eCrime for 2018 was the continued rise of “Big Game Hunting,” the practice of combining targeted, intrusion-style tactics for the deployment of ransomware across large organizations.

Another trend identified by CrowdStrike Intelligence was the increased collaboration between highly sophisticated eCrime threat actors. The use of geo-targeting to support multiple eCrime families was observed through a variety of tactics.

The industries at the top of the target list for malware-free intrusions include media, technology and academia, highlighting the need to aggressively strengthen their defenses against more sophisticated, modern attacks.

CrowdStrike identified several targeted intrusion campaigns by China, Iran and Russia, focused on the telecommunications sector and likely supporting state-sponsored espionage activities. Subsequent lures to drive more effective social engineering campaigns resulted in compromising telecom customers, including government entities.

CrowdStrike observed an increasing operational tempo from China-based adversaries, which is only likely to accelerate as US-China relations continue to be strained.
