Our SNOC group leveraged the operational excellence honed at these occasions, mixing state-of-the-art safety instruments with real-time community monitoring to make sure seamless occasion operations.
The Splunk Cloud was used as the info platform, including Apps for information ingestion:
With these integrations, our SOC group was capable of construct a CISO degree SNOC dashboard for crucial telemetry from all community and safety sources.
We additionally had SOC Supervisor degree dashboards for XDR Incidents, Firewall Occasions and DNS Safety.
We additionally related the integrations with Cisco XDR, for Dashboard visibility and Incident investigation.
We had XDR Automate workflows to advertise menace detections in Splunk to XDR Incidents, and the XDR integration again into Splunk.
The Incidents empowered the SNOC group to prioritize investigations.
Moreover, at this yr’s Cellular World Congress in Barcelona, Cisco’s ThousandEyes dashboard was instrumental in offering strong community assurance. Attendees benefited from real-time monitoring and insights into community efficiency, guaranteeing a seamless expertise from begin to end. With the aptitude to trace crucial elements just like the occasion homepage and login processes, ThousandEyes ensured that contributors might entry important sources swiftly and with out interruption. This degree of detailed visibility and management helped preserve the integrity and reliability of the community all through the occasion.
Day 1: A Check of Scale
Day 1 was all about dealing with large community exercise seamlessly. From only some workers gadgets to 1000’s of gadgets connecting concurrently, our firewall and community monitoring techniques carried out flawlessly, processing a excessive quantity of site visitors whereas sustaining pinpoint visibility. The strong efficiency of our Cisco safety options reaffirmed that, whether or not in a managed lab setting or amidst a vibrant convention, community resilience is just not negotiable.
Day 2: When a Russian Menace Tried to Crash the Social gathering
Simply as you suppose the one surprises at MWC 2025 are the revolutionary tech and spontaneous demos, our firewall logs gave us an surprising twist. On Day 2, our vigilant monitoring detected an anomalous occasion: a privilege escalation occasion coming from a Russian supply.
Our technical maestro, Jorge Quintero, instantly flagged this as a possible high-risk occasion – a scenario the place an endpoint could be compromised. The logs confirmed a sample according to C2 communications, prompting a fast investigation and swift remediation measures. In true SNOC model, we ensured that any unwelcome visitor was proven the door earlier than it might wreak havoc. (It appears even at MWC, cyber adversaries can’t resist the attract of the get together!)
What actually stood out on this IDS occasion was a crafted plain-text script working on port 80 with Web Explorer (sure – nonetheless in use).
The Snort signature that was triggered additionally highlighted two principal methods getting used:
Utilizing public generative AI instruments, the evaluation of the payload yielded the next outcomes, revealing constant patterns of malicious exercise — together with makes an attempt to establish anti-malware instruments (possible for elimination to keep up persistence) and probably escalate privileges additional.
Lastly, what confirmed our suspicions (in the event that they weren’t already) got here from Talos and AlienVault menace intelligence. This IP deal with (belonging to the Russian Federation) had already been flagged for malicious exercise.
Day 3: Cryptomining — The Story of the Good and the Evil
Day 3 introduced an fascinating matter to our consideration — cryptomining. From its humble beginnings to the multi-billion-dollar business, it’s at the moment, we’ve got witnessed the rise of crypto — now extending past simply cryptocurrency to revolutionary makes use of within the fintech area, together with NFTs and extra.
Nevertheless, we’ve got additionally seen how this expertise has been leveraged by malicious actors, particularly to compromise endpoints and hijack computing sources for cryptomining.
Utilizing public generative AI instruments to decode plain textual content, we recognized mining software program (XMRig) making RPC calls to the Monero cryptocurrency community. Now, it’s price highlighting that, though suspicious, this might nonetheless be a legit case of an endpoint working mining software program.
Nevertheless, the illegitimate nature of this exercise was confirmed once more by Talos and AlienVault intelligence. The general public IP deal with in use had already been flagged for involvement in malicious cryptomining operations.
Day 4: Slowdown and Occasion Wrap-Up!
Day 4 confirmed a slowdown in exercise, making it a threat-free day and giving us time to research and combination your complete dataset from the occasion. Listed below are a few key takeaways from the firewall evaluation:
1. EVE (Encrypted Visibility Engine): Paving the best way for encrypted site visitors evaluation.
Cisco’s Encrypted Visibility Engine (EVE) has confirmed that the innovation of latest years is important. Monitoring at Fira was performed completely utilizing IDS (Intrusion Detection System) with passive evaluation. Even with out decryption capabilities, we have been capable of establish threats inside encrypted site visitors, in addition to the processes producing these site visitors stream.
2. Occasion-driven analytics, powered by Splunk
The Cisco + Splunk story is a match made in heaven. With Cisco’s depth and breadth in safety and a powerful portfolio, mixed with Splunk’s world-class observability and adaptability, we have been capable of construct highly effective, actionable dashboards for simple consumption by the SNOC group.
Under is the aggregated information for your complete occasion — protecting the whole lot from connection occasions, file occasions, and intrusion occasions to a prioritized set of incidents recognized all through the conference.
This included DNS safety blocks, defending Fira’s Community attendees at MWC, from malicious web sites. Over 14,400 apps have been seen on the MWC community.
Wanting Forward
The surprising incident on Day 2 solely bolstered one important lesson: in at the moment’s hyper-connected world, innovation should at all times be matched with rigorous safety. As we replicate on the successes of MWC 2025, we’re already planning enhancements to our menace detection and incident response capabilities, drawing on each our MWC, Black Hat, and NFL experiences.
Cisco’s SNOC Workforce stays dedicated to staying one step forward, turning each problem into a chance to innovate and defend. Whether or not it’s managing tens of 1000’s of connections or intercepting a rogue C2 sign, we’re prepared to make sure that the digital future is as safe as it’s sensible.
