Cloudflare on Monday said it blocked the largest distributed denial-of-service (DDoS) attack ever recorded, at 11.5 Tbps (Terabits per second).
In a short message on X, Cloudflare only shared that the attack was a UDP flood mainly sourced from Google Cloud infrastructure, which lasted approximately 35 seconds.
“Cloudflare’s defenses have been working overtime. Over the past few weeks, we’ve autonomously blocked hundreds of hyper-volumetric DDoS attacks, with the largest reaching peaks of 5.1 Bpps and 11.5 Tbps. The 11.5 Tbps attack was a UDP flood that mainly came from Google Cloud,” the company said.
In a Tuesday update, Cloudflare said that Google Cloud was one source of attack, but not the majority, and that several IoT and cloud providers were used to launch the assault.
“Defending against this class of attack is an ongoing priority for us, and we’ve deployed numerous strong defenses to keep users safe, including robust DDoS detection and mitigation capabilities,” a Google Cloud spokesperson told SecurityWeek.
“Our abuse defenses detected the attack, and we followed proper protocol in customer notification and response. Initial reports suggesting that the majority of traffic came from Google Cloud are not accurate,” the spokesperson said.
A UDP flood attack consists of a high volume of UDP (User Datagram Protocol) packets being sent to a target, which becomes overwhelmed and unresponsive when attempting to process and respond to them.
Because UDP packets are small and the receiver spends resources trying to process them, the attackers also increased the packet rate to 5.1 Bpps (billion packets per second) to deplete those resources and take down the target.
This record-setting DDoS attack takes the lead as the largest in history roughly three months after Cloudflare blocked a 7.3 Tbps DDoS attack.
Seen in mid-May, the assault targeted a hosting provider and lasted for only 45 seconds. Approximately 37.4 Tb of traffic, or the equivalent of over 9,000 HD movies, was delivered in the timeframe.
The same as the newly observed attack, the May DDoS assault mainly consisted of UDP floods. It originated from over 122,000 IP addresses.
Cloudflare mitigated 27.8 million DDoS attacks in the first half of 2025, a number that surpassed the total observed in 2024 (21.3 million HTTP and Layer 3/4 DDoS attacks).

The Israeli spyware maker now faces the dilemma of whether to continue its relationship with U.S. Immigration and Customs Enforcement and help fuel its mass deportations program.
U.S. Immigration and Customs Enforcement (ICE) signed a contract last year with Israeli spyware maker Paragon worth $2 million.
Shortly after, the Biden administration put the contract under review, issuing a “stop work order,” to determine whether the contract complied with an executive order on commercial spyware, which restricts U.S. government agencies from using spyware that could violate human rights or target Americans abroad.
Almost a year later, when it looked like the contract would just run out and never become active, ICE lifted the stop work order, according to public records.
“This contract is for a fully configured proprietary solution including license, hardware, warranty, maintenance, and training. This modification is to lift the stop work order,” read an update dated August 30 on the U.S. government’s Federal Procurement Data System, a database of government contracts.
Independent journalist Jack Poulson was the first to report the news in his newsletter.
Paragon has for years cultivated the image of being an “ethical” and responsible spyware maker, in contrast with controversial spyware purveyors such as Hacking Team, Intellexa, and NSO Group. On its official website, Paragon claims to provide its customers with “ethically based tools, teams, and insights.”
The spyware maker faces an ethical dilemma. Now that the contract with ICE’s Information Technology Division is active, it’s up to Paragon to decide whether it wants to continue its relationship with ICE, an agency that has dramatically ramped up mass deportations and expanded its surveillance powers since Donald Trump took over the White House.
Emily Horne, a spokesperson for Paragon, as well as executive chairman John Fleming, did not respond to a request for comment.
In an attempt to show its good faith, in February of this year, Fleming told TechCrunch that the company only sells to the U.S. government and other unspecified allied countries.
Paragon has already had to face a thorny ethical dilemma. In January, WhatsApp revealed that around 90 of its users, including journalists and human rights workers, had been targeted with Paragon’s spyware, called Graphite. In the following days and weeks, Italian journalist Francesco Cancellato and several local pro-immigration activists came forward saying they were among the victims.
In response to this scandal, Paragon cut ties with the Italian government, which had in the meantime launched an inquiry to determine what happened. Then, in June, digital rights research group Citizen Lab confirmed that two other journalists, an unnamed European and a colleague of Cancellato, had been hacked with Paragon’s spyware.
An Italian parliament committee concluded that the spying of the pro-immigration activists was legal, but it also claimed that there was no evidence that Italy’s intelligence agencies, former Paragon customers, had targeted Cancellato.
John Scott-Railton, a senior researcher at Citizen Lab, who has investigated cases of spyware abuse for more than a decade, told TechCrunch that “these tools were designed for dictatorships, not democracies built on liberty and protection of individual rights.”
The researcher said that even spyware is “corrupting,” which is why “there’s a growing pile of spyware scandals in democracies, including with Paragon’s Graphite. Worse, Paragon is still shielding spyware abusers. Just look at the still-unexplained hacks of Italian journalists.”

Update September 04, 06:27 EDT: Updated the list of cybersecurity companies whose Salesforce instances were breached in the Salesloft supply chain attack.
Workiva, a leading cloud-based SaaS (Software as a Service) provider, notified its customers that attackers who gained access to a third-party customer relationship management (CRM) system stole some of their data.
The company's cloud software helps collect, connect, and share data for financial reports, compliance, and audits. It had 6,305 customers at the end of last year and reported revenues of $739 million in 2024.
Its customer list includes 85% of the Fortune 500 companies and high-profile clients such as Google, T-Mobile, Delta Air Lines, Wayfair, Hershey, Slack, Cognizant, Santander, Nokia, Kraft Heinz, Wendy's, Paramount, Air France KLM, Mercedes-Benz, and more.
According to a private email notification sent to affected Workiva customers last week and seen by BleepingComputer, the threat actors exfiltrated a limited set of business contact information, including names, email addresses, phone numbers, and support ticket content.
"This is similar to recent events that have targeted several large organizations. Importantly, the Workiva platform and any data within it were not accessed or compromised," the company explained. "Our CRM vendor notified us of unauthorized access via a connected third-party application."
Workiva also warned impacted customers to remain vigilant, as the stolen information could be used in spear-phishing attacks.
"Workiva will never contact anyone by text or phone to request a password or any other secure details. All communications from Workiva come through our trusted official support channels," it said.
Salesforce data breaches
While Workiva didn't share more details regarding this attack, BleepingComputer has learned that this incident was part of the recent wave of Salesforce data breaches linked to the ShinyHunters extortion group that impacted many high-profile companies.
Most recently, Cloudflare disclosed that it was forced to rotate 104 Cloudflare platform-issued tokens stolen by ShinyHunters threat actors, who gained access to the Salesforce instance used for customer support and internal customer case management in mid-August.
ShinyHunters has been targeting Salesforce customers in data theft attacks using voice phishing (vishing) since the start of the year, impacting companies such as Google, Cisco, Allianz Life, Farmers Insurance, Workday, Qantas, Adidas, and LVMH subsidiaries, including Dior, Louis Vuitton, and Tiffany & Co.
More recently, the extortion group has shifted to using stolen OAuth tokens for Salesloft's Drift AI chat integration with Salesforce to gain access to customer Salesforce instances and extract sensitive information, such as passwords, AWS access keys, and Snowflake tokens, from customer messages and support tickets.
Using this method, ShinyHunters also gained access to a small number of Google Workspace accounts in addition to stealing Salesforce CRM data and breaching the Salesforce instances of multiple cybersecurity companies, including Zscaler, Tenable, CyberArk, Elastic, BeyondTrust, Proofpoint, JFrog, Rubrik, Cato Networks, and Palo Alto Networks.
Huawei has already ‘built an ecosystem entirely independent of the United States’, according to a senior executive.

China has virtually overcome crippling US tech restrictions, according to a senior executive at Huawei Technologies, as mainland-developed computing infrastructure, AI systems and other software now rival those from the world’s largest economy.
Shenzhen-based Huawei, which was added to Washington’s trade blacklist in May 2019, has already “built an ecosystem entirely independent of the United States”, said Tao Jingwen, president of the firm’s quality, business process and information technology management department, at an event on Wednesday in Guiyang, capital of southwestern Guizhou province.
Tao highlighted the privately held company’s resilience at the event, as he discussed some of the latest milestones in its journey towards tech self-sufficiency.
That industry-wide commitment to tech self-reliance would enable China to “surpass the US in terms of artificial intelligence applications” on the back of the country’s “extensive economy and business scenarios”, he said.
His remarks reflected Huawei’s efforts to surmount tightened US control measures and heightened geopolitical tensions, as the company pushes the boundaries in semiconductors, computing power, cloud services, AI and operating systems.
Tao’s presentation was made on the same day that Huawei said users of token services on its cloud platform had access to its CloudMatrix 384 system, which is a cluster of 384 Ascend AI processors – spread across 12 computing cabinets and four bus cabinets – that delivers 300 petaflops of computing power and 48 terabytes of high-bandwidth memory. A petaflop is 1,000 trillion calculations per second.
