In the tumultuous world of cybersecurity, where relentless storms of cyber threats constantly loom on the horizon, Distributed Denial of Service (DDoS) attacks have emerged as the fiercest tempests. As we approach 2024, the DDoS battleground is more ferocious than ever, especially in the Asian region, where the thunderclouds of cyber warfare gather ominously. In this gripping narrative, we plunge into the heart-pounding saga of how Nexusguard, the valiant guardian of digital fortresses, fearlessly thwarted one of the most colossal and malevolent DDoS attacks ever witnessed, unleashing unprecedented drama and heroism in the process.
The Target: A Desperate E-commerce Citadel
The epic tale begins with a Singapore-registered e-commerce empire, its digital realm hosted upon a mighty cloud provider's celestial stronghold, firmly anchored in the heart of Singapore. This fortress thrived on the lifeblood of its APIs (Application Programming Interfaces), the very heart and soul of its commerce dominion, leaving it perilously exposed to the malicious storms of DDoS attacks.
Attack Autopsy: The Relentless Prologue
The storm's ominous rumblings began with a relentless reconnaissance phase, spanning from the 5th to the 7th of September. These were no ordinary attacks but a calculated probing, akin to shadowy spies skulking in the night, seeking chinks in the fortress's digital armor. A barrage of minor application-layer skirmishes rained down upon various domains and IP addresses of the target, their eerily similar signatures whispering secrets of sinister intent. The attackers, like masterful tacticians, gauged the fortress's strengths, identifying assets and assessing security postures.
Suddenly, the storm's ferocity intensified. The probing transitioned into frenzied volumetric attacks, each unleashing a tempest of chaos that raged for a brief but blistering 27 minutes. The attackers, relentless in their quest for vulnerability, seemed to be masters of deception, cloaking their intentions in the shroud of Asian time zones, launching their raids in the afternoon and always ceasing just before the strike of the Singapore midnight .
In a shocking crescendo, the attackers unleashed their final volley before retreating into the night. It was a series of request-based application DDoS attacks, a frenetic torrent of 100-160 thousand requests per second. This was their dark dance, testing their tools and gauging the abyss of their resources.
The morning of the 8th of September dawned with a sinister calm, shrouding the e-commerce realm in eerie silence. But, unbeknownst to the fortress, the storm was brewing on the horizon. In the languid mid-afternoon, the first cannonball struck: a 120Gbps TCP Ack flood attack. The very earth quaked as this ominous harbinger sought to drown the fortress in a torrent of malicious acknowledgments.
However, this was but the first act in the saga. As the midnight hour chimed, the storm unleashed its true fury. A cataclysmic 700Gbps volumetric DDoS tempest descended upon the fortress, unleashing a torrential deluge of 79 million packets per second. This marked the darkest hour, an epoch-defining moment as the largest DDoS attack ever launched and subsequently mitigated within the storied annals of Singaporean business.
Throughout the day, the tempest's relentless wrath continued, launching several 30-to-60 minute squalls, each ranging from 500 to 700Gbps. The storm's origins were shrouded in mystery, launching attacks from networks across the world. It was as if the attackers were orchestrating a symphony of mayhem, testing different battalions of their botnet army, strategically distributing their assaults to preserve their formidable might.
Attack Phase 2 - Sustained Attacks: The Fortress Holds
As the sun dipped below the horizon, the attackers paused, weary from their relentless assault. But they were not defeated, merely regrouping for the next dark chapter of their assault. On the 10th of September, they returned, like a hurricane reinvigorated, launching sustained attacks that would test the fortress's resilience to the core.
For the next 36 grueling hours, the tempest raged unabated. Attacks, each surging between 500 to 700 Gbps, rained down upon the fortress, with packets swirling at a frenzied pace of 40 to over 60 million packets per second. It was a relentless siege, a storm of unparalleled intensity, designed to shatter the fortress's defenses through sheer brute force.
But amidst this chaos, Nexusguard stood as the unwavering guardian, determined to hold the line against the relentless tempest. The tempest may have been unyielding, but the fortress's defenses held steadfast, a testament to the resilience and indomitable spirit of those who dared to defy the storm.
Attack Phase 3 - Application Layer Attacks: The Storm's Ingenious Fury
As the battle raged on, a curious pattern emerged. With the discipline only displayed by elite combat units, the attackers transitioned from strategy to strategy with precision. At the stroke of midnight, the volumetric onslaught ceased, to be immediately replaced by an insidious tactic: application-layer attacks.
These request-based attacks were a cunning ploy, utilizing compromised machines to send what appeared to be legitimate requests, a treacherous deluge aimed at overwhelming the fortress's API gateways and servers. It was a devious strategy, one that threatened to breach the fortress's inner sanctum.
But Nexusguard, armed with the power of artificial intelligence, rose to the occasion. The API service, under relentless assault, stood defiant, its defenses bolstered by Nexusguard's cutting-edge detection and authentication capabilities. At its zenith, the onslaught reached a staggering 294 thousand requests per second, a testament to the attackers' vast and formidable botnet army.
As the storm's fury raged on, Nexusguard delved deeper, peering into the abyss of the attackers' operations. It was a chilling revelation, unveiling a complex web of botnets, each a dark instrument of destruction. The battle was far from over; it was a struggle for the very soul of the fortress.
The Aftermath: Unveiling the Dark Secrets
During and after the tempestuous battle, Nexusguard's engineers received a barrage of emails from networks across the globe. These messages were no ordinary communiques; they were a cacophony of alarms, a chorus of digital sirens heralding an unprecedented threat. The storm's reach extended far and wide, far beyond anything ever witnessed.
This was no ordinary storm; it was a harbinger of a new breed of botnet. The sheer volume of abuse emails from across the world was a chilling testament to the storm's global reach. It was a harbinger of doom, a harbinger of Pandora and Moobot, a dark alliance of botnets unseen in their scale and ferocity.
The storm had unleashed its fury not just upon the fortress but upon the very infrastructure of the digital realm. Nexusguard's internet exchange links, some as vast as the ocean, were pushed to the brink of saturation, a testament to the tempest's potency and breadth.
