| 11 | +Using the detection IDs below, you can detect and mitigate account takeover attacks. You can monitor the number of login requests for a given software and network combination, as well as the percentage of login errors. When it reaches a suspicious level, you can prevent these attacks by using [custom rules](/waf/custom-rules/), [rate limiting rules](/waf/rate-limiting-rules/), and [Workers](/workers/). |
| 12 | + |
| 13 | +| Detection ID | Description | |
| 14 | +| ------------ | ---------------------------------------- | |
| 15 | +| `201326592` | Observes all login failures to the zone. | |
| 16 | +| `201326593` | Observes all login traffic to the zone. | |
| 17 | +| `201326598` | Sets a dynamic threshold based on the normal traffic that is unique to the zone.<br /><br /> When the ID matches a login failure, Bot Management sets the [bot score](/bots/concepts/bot-score/) to 29 and uses [anomaly detection](/bots/concepts/bot-detection-engines/#anomaly-detection-enterprise) as its score source. | |

| 19 | +### Challenges for account takeover detections |
| 20 | + |
| 21 | +Cloudflare's [Managed Challenge](/cloudflare-challenges/challenge-types/challenge-pages/#managed-challenge-recommended) can limit brute-force attacks on your login endpoints. |
| 22 | + |
| 23 | +To access account takeover detections: |

| 30 | + 3. Under **Custom Rules**, select **Create rule**. |
| 31 | + 4. Fill out the form using **Bot Detection IDs** along with other necessary information. |
| 32 | + 5. Select **Save as draft** to return to it later, or **Deploy** to deploy the rule. |

| 51 | +### Limit logins with account takeover detections |
| 52 | + |
| 53 | +Rate limiting rules can limit the number of logins from a particular IP, JA4 Fingerprint, or country. |
| 54 | + |
| 55 | +To use rate limiting rules with account takeover detections: |

| 61 | + 2. Go to **Security** > **WAF**. |
| 62 | + 3. Under **Rate limiting rules**, select **Create rule**. |
| 63 | + 4. Fill out the form using the **Custom expression builder** and `cf.bot_management_detection_ids` along with other necessary information. |
| 64 | + 5. Select **Save as draft** to return to it later, or **Deploy** to deploy the rule. |

| 79 | +The rule can be enhanced with Leaked Credential Checks. Refer to the [WAF documentation](/waf/detections/leaked-credentials/) for more information on how to include leaked credentials and account takeover detections in a rate limiting rule. |
