MySQL servers are being targeted by the 'Ddostf' malware botnet to enslave them for a DDoS-as-a-Service platform whose firepower is rented to other cybercriminals. Exploitation of UDF. The attackers are scanning the internet for exposed MySQL servers and, when found, attempt to breach them by brute-forcing administrator credentials.

DDoS attacks are cyber threats aimed at disrupting online services by flooding them with excessive traffic. Layer 7 DDoS attacks are a new breed of DDoS that allows attackers to do much more damage with fewer resources.

Publicly-accessible Docker Engine API instances are being targeted by threat actors as part of a campaign designed to co-opt the machines into a distributed denial-of-service botnet dubbed OracleIV. "Attackers are exploiting this misconfiguration to deliver a malicious Docker container, built from an image named 'oracleiv latest' and containing Python malware compiled as an ELF executable," Cado researchers Nate Bill and Matt Muir said. The malicious activity starts with attackers using an HTTP POST request to Docker's API to retrieve a malicious image from Docker Hub, which, in turn, runs a command to retrieve a shell script from a command-and-control server.

Update November 09, 17:19 EST: A threat group known as Anonymous Sudan claimed that they were the ones who took down Cloudflare's website in a distributed denial-of-service attack. Cloudflare confirmed that the outage resulted from a DDoS attack that only affected the www.

OpenAI has been addressing "Periodic outages" due to DDoS attacks targeting its API and ChatGPT services within the last 24 hours. While the company didn't immediately provide any details on the root cause of these incidents, OpenAI confirmed earlier today that they're linked to ongoing distributed denial-of-service attacks.

Russian financial organization Sberbank states in a press release that two weeks ago it faced the most powerful distributed denial of service attack in recent history. Russian outlet Interfax reports that the attack reached one million requests per second, which the organization said was roughly four times the size of the most powerful DDoS Sberbank had experienced up until then.

Cloudflare on Thursday said it mitigated thousands of hyper-volumetric HTTP distributed denial-of-service (DDoS) attacks that exploited a recently disclosed flaw called HTTP/2 Rapid Reset, 89 of...

Cloudflare says the number of hyper-volumetric HTTP DDoS attacks recorded in the third quarter of 2023 surpasses every previous year, indicating that the threat landscape has entered a new chapter. A Cloudflare report shared with BleepingComputer reveals that, during Q3 2023, the internet company mitigated thousands of hyper volumetric HTTP DDoS attacks.

Find out what security teams should do now, and hear what Cloudflare's CEO has to say about this DDoS. Google, AWS and Cloudflare have reported the exploitation of a zero-day vulnerability named HTTP/2 Rapid Reset and tracked as CVE-2023-44487, which is currently used in the wild to run the largest Distributed Denial of Service attack campaigns ever seen. The HTTP/2 Rapid Reset attack works by leveraging HTTP/2's stream cancellation feature: The attacker sends a request and cancels it immediately.

The method relies on stream multiplexing, a feature of the HTTP/2 protocol that allows multiple HTTP requests to be sent to a server on a single TCP connection. A feature of the protocol's streaming capability is the ability to send a request and soon after cancel that request, an action known as resetting the request's stream.
