Mundane or Malicious? Cloudflare Debunks Cyber-Strike Theory in Venezuela

What originated as a compelling narrative of “pre-emptive cyber-strike” has concluded in a far more pedestrian fashion: Cloudflare maintains that the disruptions within Venezuelan networks were likely the result of mere digital negligence rather than a clandestine operation.

The catalyst for this discourse was an analysis by red-team engineer Graham Helton. He took note of Donald Trump’s assertions that the United States had deployed “specific competencies” to extinguish the lights in Caracas prior to military engagement, alongside remarks from General Dan Kane, Chairman of the Joint Chiefs of Staff, regarding the involvement of US Cyber Command. Helton endeavored to scrutinize infrastructure records for digital footprints, delving into Cloudflare Radar to identify traffic anomalies.

His investigation centered on AS8048, the autonomous system of the state-owned provider CANTV. He observed that on January 2nd—the eve of the military operation—certain network prefixes were suddenly diverted through erratic paths involving the Italian transit provider Sparkle and Colombia’s GlobeNet. By cross-referencing this with RIPE NCC data, Helton postulated that such routing could theoretically facilitate a man-in-the-middle (MITM) attack, allowing for the surreptitious interception or surveillance of traffic.

This week, Cloudflare undertook a granular deconstruction of the episode. The company’s Principal Network Engineer, Brighton Herdes, corroborated Helton’s primary observation: a BGP route leak had indeed occurred. This phenomenon resembles a scenario where a network participant erroneously propagates incorrect routing information to its neighbors, causing traffic to traverse a circuitous, sluggish, and unreliable path. However, Cloudflare’s conclusions diverge from the narrative of malicious intent; BGP leaks are a perpetual occurrence, typically born of routine configuration blunders rather than offensive maneuvers.

Herdes specifically elucidated why the observed pattern was ill-suited for a MITM operation. The leak resulted in a “worse” route, whereas a sophisticated interloper would strive for the opposite: appearing as the most “efficient” path to entice traffic. Furthermore, the affected prefixes belonged to Dayco Telecom (AS21980), for which CANTV (AS8048) already serves as a legitimate provider. Consequently, CANTV already resides “on the path” legally, obviating the need for a theatrical routing deception.

Cloudflare posits that the most plausible explanation is excessively broad route export policies at CANTV directed toward one of its upstreams. The firm also noted that such leaks are commonplace within the region, with AS8048 experiencing numerous similar incidents in recent weeks. To mitigate such occurrences, Herdes advocated for more rigorous route validation mechanisms, including those outlined in RFC 9234 and the continued maturation of the RPKI ecosystem.

The ultimate takeaway is that while public metrics do reflect a network anomaly prior to the U.S. operation, Cloudflare perceives no convincing evidence of a deliberate assault. The precise methods by which the lights were extinguished in Caracas remain shrouded in secrecy, while the primary suspect in the digital realm appears to be the temperamental and often misconfigured BGP protocol.
