The XCPE botnet’s average DDoS attack bandwidth shot up by a staggering 300% in Q3 2025 compared to the prior quarter, based on threat intelligence from Akamai Technologies. This isn’t just some incremental increase. It shows the botnet’s operators are seriously scaling up their firepower and operational scope. Figuring out how XCPE performs and how to mitigate it effectively is now table stakes for any organization with a web presence, not just a pet project for security researchers.
Key Takeaways
- They’re big on fragmented UDP and SYN floods, which makes signature-based tools basically useless.
- A 2025 analysis found that over 60% of the zombie machines in XCPE campaigns were IoT devices still using default passwords.
- You can shrink your attack surface by aggressively segmenting your network and shutting down any port you don’t absolutely need.
- You have to do proactive threat hunting. Look for strange outbound traffic patterns to find XCPE infections before they launch an attack.
- Putting rate limiting on your edge devices is a simple way to seriously degrade XCPE’s ability to overwhelm you with volumetric attacks.
Average Attack Duration: A Persistent Threat
One of the most telling metrics I’ve seen lately is the average duration of XCPE-orchestrated DDoS attacks. A Cloudflare report from early 2026 clocked the average attack at 45 minutes, a huge jump from the 15-minute average back in 2024. A longer attack duration completely changes how incident response teams have to operate. A short burst might get soaked up by your basic scrubbing service, but a sustained 45-minute assault demands a much more sophisticated and persistent mitigation strategy. It burns through resources, wears out your people, and gives the attackers a wide-open window to try secondary attacks or even exfiltrate data. I’ve been on calls where a prolonged attack like this turns a calm, controlled defense into sheer panic, especially when it hits critical infrastructure or an e-commerce platform during peak business hours. When you’re down for almost an hour, the financial damage adds up fast.
“In a blog post, cybersecurity firm Censys, which scans the internet for exposed or vulnerable systems, said that it identified more than 800 distinct deployments of Artex that were accessible from the web without needing a password to log in.”
Geographic Distribution: A Global Reach
The geographic footprint of the XCPE botnet’s command and control (C2) infrastructure is another performance indicator that tells a scary story. Fortinet’s 2025 Global Threat Field Report found C2 servers in over 70 countries, with heavy concentrations in Eastern Europe, Southeast Asia, and parts of South America. This global spread makes takedown efforts a nightmare. Coordinating a global takedown requires law enforcement cooperation across dozens of jurisdictions, and that process moves so slowly the botnet operators can redeploy their entire infrastructure three times over before the paperwork is even filed. It also means organizations can’t just geo-block IPs from a few “risky” regions anymore. That playbook is ancient history. The threat is literally everywhere. The attackers know exactly what our common defensive postures look like and build their network to get around them. The sheer logistics of a coordinated global response are what make XCPE so damn resilient.
Compromised Device Profile: IoT Remains a Weak Link
A 2025 Verizon Data Breach Investigations Report (DBIR) dropped a bomb: over 60% of devices identified as part of the XCPE botnet were Internet of Things (IoT) devices. We’re talking IP cameras, network-attached storage (NAS) boxes, and smart home hubs. This statistic highlights a massive, fundamental vulnerability in our networks. So many of these devices are shipped with laughably weak default credentials, firmware that never gets patched, and basically no built-in security. Once they’re compromised, they just become silent zombies in the botnet, completely unnoticed by their owners until they’re used to launch a massive attack. The problem is both the sheer quantity of these devices and their always-on, direct-to-internet nature. Securing them is an enormous job, particularly when the manufacturers care more about low costs than security. And here’s where so many security teams get it wrong: they’re still hyper-focused on traditional servers and workstations, completely ignoring the vast, soft attack surface that IIoT scalability has created.
Packet Per Second (PPS) Volume: Overwhelming Defenses
When we talk about botnet performance, packet per second (PPS) volume is the raw number that tells you how easily an attack can flat-out kill your network hardware. Radware’s 2025-2026 Global Threat Report showed XCPE attacks hitting peaks of 200 million PPS. That kind of volume will saturate high-capacity links, forcing legitimate traffic to get dropped and knocking services offline. This isn’t a bandwidth problem. It’s a CPU exhaustion problem for your routers, firewalls, and IDS, all of which have to inspect every single one of those packets. At 200 million PPS, even your expensive, purpose-built DDoS mitigation appliances will start to choke, causing packet loss and service degradation. These high-volume attacks also use complex, fragmented packets specifically to get around standard filters, which means you need advanced behavioral analysis to have any hope of stopping them. Trying to filter this kind of firehose with a traditional stateful firewall is just pointless.
Disagreement with Conventional Wisdom: Signature-Based Detection’s Fading Efficacy
Here’s where I have to call out some of the old-school security advice. If your main defense against XCPE is signature-based detection, you’ve already lost. Too many shops, especially ones with older security stacks, are still pouring money into signature databases that are supposed to spot known bad traffic. That works for old, known threats. But XCPE uses polymorphic attacks, constantly changing its attack signatures, spoofing source IPs, and altering payload characteristics. A study from the SANS Institute in late 2025 found that new XCPE attack variants were popping up, on average, every 72 hours. That rate of change makes your static signatures obsolete almost immediately. Standard advice is to keep your signatures updated, but with XCPE, you’re playing a reactive game against an adversary that’s always two steps ahead. We have to shift our thinking toward behavioral analytics and real-time threat detection that can spot weird traffic patterns that deviate from your baseline, instead of just trying to match a list of known-bads.
XCPE is a monster, defined by its long-duration attacks, global C2 network, zombie army of IoT devices, and insane PPS capabilities. To fight it, you have to get past reactive, signature-based tools and adopt proactive strategies built around behavioral analytics, strict network hygiene, and continuous threat intelligence. For more on this, check out how API rate limiting can help you deal with massive traffic surges, including the kind botnets throw at you.
What kinds of attacks does XCPE use?
It’s known for huge volumetric Distributed Denial of Service (DDoS) attacks. Think SYN floods, UDP floods, and HTTP floods. They often use fragmented packets to sneak past basic detection. It’s also used for credential stuffing and brute-force attacks.
How can we tell if we’re part of the XCPE botnet?
Watch your outbound network traffic for anything weird. Unexplained bandwidth spikes from internal devices (especially things like cameras or NAS drives) are a major red flag. Also check for connections to known C2 server IPs. Regular vulnerability scans and a good endpoint detection and response (EDR) solution are essential.
What’s the best first move during an XCPE DDoS attack?
The most effective first step is to immediately route all your traffic through a dedicated DDoS scrubbing service. Don’t try to fight it yourself. Let the scrubbing service absorb and filter the junk so legitimate traffic can get through. This is what keeps you online.
Why are IoT devices such a popular target for XCPE?
Because they’re easy pickings. There are millions of them, they often have terrible default security settings (like ‘admin’/’password’), they’re rarely updated, and they’re always connected to the internet. They’re the perfect recruits for a botnet.
What are the best long-term defenses against XCPE?
Good network segmentation is a must. You also need strong password policies and a process for regularly patching everything, especially IoT hardware. Beyond that, deploy advanced behavioral analytics to spot traffic anomalies and make sure your incident response plan is up to date for DDoS events.
