Question 1

What is phone flood and how does it work on a technical level?

Accepted Answer

Phone flood is automatic generation of mass calls to a target number using VoIP gateways (SIP) or physical GSM devices. The system creates a continuous call queue using multithreading: each thread is one line, generating up to 3 calls per minute. With 20 threads – up to 600 calls/min, completely paralyzing even multi-channel lines.

Question 2

What is the difference between GSM flood and SIP flood in terms of network stack?

Accepted Answer

GSM flood works on the physical level of cellular networks through real SIM cards and our GSM gateways – this provides maximum anonymity and stability. SIP flood works on the application level (VoIP) using internet channels, which gives flexibility in configuring SIP headers and codecs.

Question 3

How is multi-layer anonymity and protection against tracking ensured?

Accepted Answer

We use a chain of proxy servers with IP rotation, our own GSM gateways with different SIM cards, and spoofing technology with dynamic Caller ID change. Logs are not stored, payment is accepted in cryptocurrency (BTC, USDT) through anonymous wallets. Even if one element is compromised, it is impossible to identify the customer.

Question 4

What protocols and codecs are supported for SIP flood?

Accepted Answer

Supported: SIP (UDP/TCP/TLS), RTP/RTCP, WebRTC. Codecs: G.711 (PCMA/PCMU), G.729, G.722, OPUS, iLBC, AMR. We can force transcoding to test DSP load and voice quality.

Question 5

Can I integrate your service with my own API for automation?

Accepted Answer

Yes, for corporate clients we provide REST API with Swagger documentation. You can programmatically start/stop attacks, change thread count, get metrics (CPS, ASR, PDD) in real-time via WebSocket.

Question 6

What is a "thread" and how does it affect intensity?

Accepted Answer

A thread is one simultaneous call line. One thread generates roughly 1–3 calls per minute (with a timeout between calls of 25–35 seconds). Accordingly, 10 threads give 10–30 calls per minute. We can use up to 50 threads on one number.

Question 7

What technologies do you use for anonymity?

Accepted Answer

We don't store logs, we don't require personal data, we accept crypto (BTC, USDT). All calls go through proxy chains and our own GSM gateways.

Question 8

Do you work with numbers from other countries?

Accepted Answer

Yes, global coverage: Russia, Ukraine, Belarus, Kazakhstan, all of Europe, USA, Canada, Asia, Middle East and more.

Question 10

What report do I get after the attack?

Accepted Answer

Upon request we send screenshots from the monitoring system: call counts, successful answers, average duration, time load graphs.

Question 11

What if the target number doesn't answer?

Accepted Answer

The attack is still effective. The line will be constantly busy with long beeps or busy signals, blocking incoming calls.

Question 12

Can you flood a multi-channel call center number?

Accepted Answer

Yes, we use multithreading several times the number of lines. For example, 30–40 threads for a 10-line call center.

Question 13

Are your calls distinguishable from normal ones?

Accepted Answer

Absolutely indistinguishable. Calls look like regular incoming calls from real numbers. You can show any number on the screen.

Question 14

What payment methods are available?

Accepted Answer

Mainly crypto: Bitcoin (BTC), USDT (TRC20/ERC20). Bank cards (Sber, Tinkoff, Alfa) are possible with extra fee for anonymity.

Question 15

Are there discounts for regular customers?

Accepted Answer

Yes, individual discounts for orders from $300 or from 7 days. Referral program: 10% of the referred client's order.

Question 16

How reliable is the service? Does the connection drop?

Accepted Answer

We use our own fault-tolerant GSM gateways and several backup SIP providers. We've achieved 99.9% uptime over 15 years.

Question 17

What is TDoS and how do you protect against it?

Accepted Answer

TDoS (Telephony Denial of Service) is an attack on telephony infrastructure. We conduct such tests for clients to find vulnerabilities.

Question 18

Can a blacklist block the attack?

Accepted Answer

Practically impossible. We use thousands of constantly changing number masks and Caller ID substitution. Each call can come from a unique number.

Question 19
