Windows 10: Is this a form of ddos attack?

Declan McGowan · Nov 17, 2024 at 1:18 PM

I've been getting hacked and my discord and face book names changed . They don't change my password tho so I kick them out and it's just happens again and again. Can someone take on a challenge and see who's behind this ?. Sure there using a bot net from some London vm machine website

Multi-Vector DDoS Attacks Are Becoming the Norm

Multi-Vector DDoS Attacks Are Becoming the Norm
47% of all multi-vector DDoS attacks were launched in Q4 '15

Statistics gathered by Neustar, Inc., a provider of real-time information services, shows that in the past year, and especially in the last quarter of 2015, multi-vector DDoS attacks have started to become a regular occurrence.

Details from the 2016 Neustar Security Operations Center Report reveals that attackers are starting to chain together different methods for launching DDoS attacks, either for reconnaissance, or for diverting company IT resources in different areas, so they can launch other types of attacks later on.

Multi-vector DDoS attacks are when an attacker quickly transitions from launching DDoS attacks from one form of DDoS attack (e.g.: SYN packets) to another one (Layer 7), and so on. These attacks are either launched one vector at a time, or in parallel, in order to confuse a company's IT department, strain their resources, and keep their attention on the wrong spot.

Today's leading causes of DDoS attacks

Distributed denial of service attacks are growing ever bigger. Here's what's causing them.
Last fall, we saw the biggest distibuted denial of service (DDoS) attack ever. This year we'll see even bigger ones. According to Akamai's latest State of the Internet Security report, here's what's behind them.

Behind today's DDoS attacks you'll find botnets and they're using the same old techniques hackers have always used to bring down your servers.

Akamai

First, you should know that while the total DDoS attacks only increased by 4 percent from Q4 2015 to Q4 2016, there was a 140 percent increase in attacks greater than 100 gigabits per second (Gbps). In short, we're not seeing that many more DDoS assaults, but they are getting much worse.

Of the most recent mega 100Gbps attacks in the last quarter, most of them were directly attributed to the Mirai botnet. The Mirai botnet works by exploiting the weak security on many Internet of Things (IoT) devices. The program finds its victims by constantly scanning the internet for IoT devices, which use factory default or hard coded usernames and passwords...

Microsoft response to early June outage from Layer 7 DDoS attacks

Summary Beginning in early June 2023, Microsoft identified surges in traffic against some services that temporarily impacted availability. Microsoft promptly opened an investigation and subsequently began tracking ongoing DDoS activity by the threat actor that Microsoft tracks as Storm-1359. These attacks likely rely on access to multiple virtual private servers (VPS) in conjunction with rented cloud infrastructure, open proxies, and DDoS tools. We have seen no evidence that customer data has been accessed or compromised. This recent DDoS activity targeted layer 7 rather than layer 3 or 4. Microsoft hardened layer 7 protections including tuning Azure Web Application Firewall (WAF) to better protect customers from the impact of similar DDoS attacks. While these tools and techniques are highly effective at mitigating the majority of disruptions, Microsoft consistently reviews the performance of its hardening capabilities and incorporates learnings into refining and improving their effectiveness. Customers should review the technical details and recommended actions section of this blog to increase the resilience of their environments to help mitigate similar attacks. Technical Details Microsoft assessed that Storm-1359 has access to a collection of botnets and tools that could enable the threat actor to launch DDoS attacks from multiple cloud services and open proxy infrastructures. Storm-1359 appears to be focused on disruption and publicity. Storm-1359 has been observed launching several types of layer 7 DDoS attack traffic:

HTTP(S) flood attack – This attack aims to exhaust the system resources with a high load of SSL/TLS handshakes and HTTP(S) requests processing. In this case, the attacker sends a high load (in the millions) of HTTP(S) requests that are well distributed across the globe from different source IPs. This causes the application backend to run out of compute resources (CPU and memory).

Cache bypass – This attack attempts to bypass the CDN layer and can result in overloading the origin servers. In this case, the attacker sends a series of queries against generated URLs that force the frontend layer to forward all the requests to the origin rather serving from cached contents.

Slowloris – This attack is where the client opens a connection to a web server, requests a resource (e.g., an image), and then fails to acknowledge the download (or accepts it slowly). This forces the web server to keep the connection open and the requested resource in memory.

Recommendations – Layer 7 DDoS Protection Tips Microsoft recommends customers review the following mitigations to reduce their impact to layer 7 DDoS attacks:

Use layer 7 protection services such as Azure Web Application Firewall (WAF) (available with Azure Front Door, Azure Application Gateway) to protect web applications.

If using Azure WAF:

Use the bot protection managed rule set provides protection against known bad bots. For more information, see Configuring bot protection.

IP addresses and ranges that you identify as malicious should be blocked. For more information, see examples at Create and use custom rules.

Traffic from outside a defined geographic region, or within a defined region, should be blocked, rate limited or redirected to a static webpage. For more information, examples at Create and use custom rules.

Create custom WAF rules to automatically block and rate limit HTTP or HTTPS attacks that have known signatures.
