Talos ThreatSource is a regular intelligence update from Cisco Talos, highlighting the biggest threats each week and other security news.
Welcome to this week’s Threat Source newsletter — the perfect place to get caught up on all things Talos from the past week.
If you haven’t yet, there’s still time to register for this year’s Talos Threat Research Summit — our second annual conference by defenders, for defenders. This year’s Summit will take place on June 9 in San Diego — the same day Cisco Live kicks off in the same city. We sold out last year, so hurry to register!
Weeks after our initial DNSpionage post, we published an update to the malware, including outlining new malware the actors are distributing and a growth in the number of targets.
Finally, we also have our weekly Threat Roundup, which you can find on the blog every Friday afternoon. There, we go over the most prominent threats we’ve seen (and blocked) over the past week.
Location: Salt Lake City, Utah
Synopsis: Join Nick Biasini as he takes part in a day-long education event on all things Cisco. Nick will be specifically highlighting the work that Talos does as one part of the many breakout sessions offered at Cisco Connect. This session will cover a brief overview of what Talos does and how we operate. Additionally, he'll discuss the threats that are top-of-mind for our researchers and the trends that you, as defenders, should be most concerned about.
Description: Cisco Talos discovered a new cyber threat campaign called "Sea Turtle," which is targeting public and private entities, including national security organizations, located primarily in the Middle East and North Africa. The ongoing operation likely began as early as January 2017 and has continued through the first quarter of 2019. The investigation revealed that at least 40 different organizations across 13 different countries were compromised during this campaign. Talos assesses with high confidence that this activity is being carried out by an advanced, state-sponsored actor that seeks to obtain persistent access to sensitive networks and systems.
