Massive 7.3 Tbps DDoS Attack Delivers 37.4 TB in 45 Seconds, Targeting Hosting Provider

Massive 7.3 Tbps DDoS Attack Delivers 37.4 TB in 45 Seconds, Targeting Hosting Provider

Jun 20, 2025 Cyber Attack / Botnet
Cloudflare on Thursday said it autonomously blocked the largest distributed denial-of-service (DDoS) attack ever recorded, which hit a peak of 7.3 terabits per second (Tbps). The attack, which was detected in mid-May 2025, targeted an unnamed hosting provider. "Hosting providers and critical Internet infrastructure have increasingly become targets of DDoS attacks," Cloudflare's Omer Yoachimik said . "The 7.3 Tbps attack delivered 37.4 terabytes in 45 seconds." Earlier this January, the web infrastructure and security company said it had mitigated a 5.6 Tbps DDoS attack aimed at an unnamed internet service provider (ISP) from Eastern Asia. The attack originated from a Mirai-variant botnet in October 2024. Then in April 2025, Cloudflare revealed it defended against a massive 6.5 Tbps flood that likely emanated from Eleven11bot, a botnet comprising roughly 30,000 webcams and video recorders. The hyper-volumetric attack lasted about 49 seconds. The 7.3 Tbps...
Hackers Abuse Russian Bulletproof Host Proton66 for Global Attacks and Malware Delivery

Hackers Abuse Russian Bulletproof Host Proton66 for Global Attacks and Malware Delivery

Apr 21, 2025 Vulnerability / Threat Intelligence
Cybersecurity researchers have disclosed a surge in "mass scanning, credential brute-forcing, and exploitation attempts" originating from IP addresses associated with a Russian bulletproof hosting service provider named Proton66 . The activity, detected since January 8, 2025, targeted organizations worldwide, according to a two-part analysis published by Trustwave SpiderLabs last week.  "Net blocks 45.135.232.0/24 and 45.140.17.0/24 were particularly active in terms of mass scanning and brute-force attempts," security researchers Pawel Knapczyk and Dawid Nesterowicz said . "Several of the offending IP addresses were not previously seen to be involved in malicious activity or were inactive for over two years." The Russian autonomous system Proton66 is assessed to be linked to another autonomous system named PROSPERO. Last year, French security firm Intrinsec detailed their connections to bulletproof services marketed on Russian cybercrime forums under ...
OPSEC Failure Exposes Coquettte’s Malware Campaigns on Bulletproof Hosting Servers

OPSEC Failure Exposes Coquettte's Malware Campaigns on Bulletproof Hosting Servers

Apr 04, 2025 Threat Intelligence / Malware
A novice cybercrime actor has been observed leveraging the services of a Russian bulletproof hosting ( BPH ) provider called Proton66 to facilitate their operations. The findings come from DomainTools, which detected the activity after it discovered a phony website named cybersecureprotect[.]com hosted on Proton66 that masqueraded as an antivirus service. The threat intelligence firm said it identified an operational security (OPSEC) failure in the domain that left its malicious infrastructure exposed, thereby revealing the malicious payloads staged on the server.  "This revelation led us down a rabbit hole into the operations of an emerging threat actor known as Coquettte – an amateur cybercriminal leveraging Proton66's bulletproof hosting to distribute malware and engage in other illicit activities," it said in a report shared with The Hacker News. Proton66, also linked to another BPH service known as PROSPERO, has been attributed to several campaigns distribut...

Between Buzz and Reality: The CTEM Conversation We All Need

Between Buzz and Reality: The CTEM Conversation We All Need

Jun 24, 2025Threat Exposure Management
I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...
