Exclusive: Brazilian DDoS Mitigation Firm Huge Networks Linked to Vicious Botnet Attacks on Domestic ISPs

Breaking: Huge Networks CEO Blames Breach as Evidence Emerges

A Brazilian firm that sells distributed denial-of-service (DDoS) protection actively powered the very botnet battering local Internet service providers, according to an investigation. The company’s CEO insists malicious code found in an exposed online archive stems from a security breach—and that a rival is framing his business.

"This was a targeted attack to destroy our reputation," said the CEO of Huge Networks, speaking on condition of anonymity due to ongoing legal concerns. "A competitor likely exploited a vulnerability in our infrastructure to stage the campaign."

Exposed Archive Reveals SSH Keys and Python Malware

Earlier this month, a trusted source who requested anonymity shared a file archive left exposed in an open directory. The archive contained Portuguese-language Python scripts and private SSH authentication keys belonging to Huge Networks' chief executive.

The material (see background) shows the threat actor maintained root access to the company’s internal systems for at least two years. Using that foothold, they built a massive botnet by scanning the internet for insecure home routers and misconfigured DNS servers.

How the Botnet Works: DNS Reflection and Amplification

The botnet predominantly used DNS reflection attacks, exploiting servers configured to respond to queries from any IP address. By spoofing the target’s address, attackers made the DNS replies flood the victim’s network.

Amplification was key: an attacker could send a 100-byte request that triggers a 6,000-byte response. With tens of thousands of compromised devices and open resolvers, the combined bandwidth overwhelmed even large ISPs.

Background: Huge Networks’ Rise and Fall from Grace

Huge Networks was founded in Miami, Florida, in 2014 but operates primarily in Brazil. It began by protecting gaming servers and later pivoted to ISP-focused DDoS mitigation.

Despite its anti-DDoS mission, the company had no public abuse complaints and no links to known DDoS-for-hire services. The CEO’s statement suggests the recent attacks are not sanctioned by the firm. However, the evidence of a persistent compromise raises serious questions about network security.

What This Means for Brazilian ISPs and the Industry

The revelation undermines trust in one of Brazil’s few local DDoS mitigation providers. If a boutique security firm can be turned into a weapon, every ISP must re-evaluate its third-party defenses.

"This shows no company is immune," a senior security researcher told us. "Even DDoS protectors can be co-opted to attack the very clients they claim to shield."

For Brazilian ISPs that have suffered years of relentless attacks, the news offers a suspect but little solace. The botnet remains active, and attribution may not stop the bandwidth-crippling floods.

Security Experts Call for Audits

Industry observers urge all Brazilian network operators to audit their upstream providers for vulnerabilities. The threat actor’s ability to abuse Huge Networks’ infrastructure for years indicates systemic weaknesses.

"We’re talking about root access to a DDoS mitigation company’s core—that’s like giving the thief the keys to the safe," said a cybersecurity analyst at a major university.

What Huge Networks Must Do Next

The CEO has pledged a full forensic investigation and cooperation with law enforcement. But regaining the trust of clients will require transparent disclosure of how the breach occurred and how future incidents will be prevented.

For now, the race is on to identify the botnet’s command-and-control infrastructure and dismantle it before the next wave of attacks.
