Questo documento descrive un tipo di risultato di minaccia in Security Command Center. I risultati delle minacce vengono generati dai
rilevatori di minacce quando rilevano
una potenziale minaccia nelle tue risorse cloud. Per un elenco completo dei risultati relativi alle minacce disponibili, consulta l'Indice dei risultati relativi alle minacce.
Panoramica
Un processo è iniziato con il reindirizzamento del flusso a un socket connesso remoto. La generazione
di una shell connessa alla rete può consentire a un malintenzionato di eseguire azioni arbitrarie
dopo una compromissione iniziale limitata.
Nome completo del progetto: il progetto Google Cloud interessato
Link correlati, in particolare i seguenti campi:
Indicatore VirusTotal: link alla pagina di analisi di VirusTotal
Nella scheda JSON, prendi nota dei seguenti campi:
resource:
project_display_name: il nome del progetto che contiene l'asset.
sourceProperties:
Reverse_Shell_Stdin_Redirection_Dst_Ip: l'indirizzo IP remoto della
connessione
Reverse_Shell_Stdin_Redirection_Dst_Port: la porta remota
Reverse_Shell_Stdin_Redirection_Src_Ip: l'indirizzo IP locale della
connessione
Reverse_Shell_Stdin_Redirection_Src_Port: la porta locale
Container_Image_Uri: il nome dell'immagine container in esecuzione.
Cerca risultati correlati che si sono verificati in un momento simile per il contenitore interessato. Questi risultati potrebbero indicare che l'attività era dannosa,
anziché un mancato rispetto delle best practice.
Rivedi le impostazioni del contenitore interessato.
Controlla il valore hash SHA-256 del file binario segnalato come dannoso su
VirusTotal facendo clic sul link nell'indicatore VirusTotal. VirusTotal è un servizio di proprietà di Alphabet che
fornisce il contesto di file, URL, domini e indirizzi IP potenzialmente
dannosi.
Per sviluppare un piano di risposta, combina i risultati dell'indagine con la ricerca MITRE e l'analisi di VirusTotal.

Threat findings are generated by\n[threat detectors](/security-command-center/docs/concepts-security-sources#threats) when they detect\na potential threat in your cloud resources. For a full list of available threat findings, see [Threat findings index](/security-command-center/docs/threat-findings-index).\n\nOverview\n\nA process started with stream redirection to a remote connected socket. Spawning\na network-connected shell can allow an attacker to perform arbitrary actions\nafter a limited initial compromise.\n\n[Cloud Run Threat Detection](/security-command-center/docs/cloud-run-threat-detection-overview) is the source\nof this finding.\n\nHow to respond\n\nTo respond to this finding, do the following:\n\nReview finding details\n\n1. Open the `Reverse Shell` finding as directed in [Reviewing\n findings](/security-command-center/docs/how-to-investigate-threats#reviewing_findings).\n Review the details on the **Summary** and **JSON** tabs.\n\n2. On the **Summary** tab, review the information in the following sections:\n\n - **What was detected** , especially the following fields:\n - **Program binary**: the absolute path of the process started with stream redirection to a remote socket\n - **Arguments**: the arguments provided when the process binary was invoked\n - **Affected resource** , especially the following fields:\n - **Resource full name** : the [full resource name](/apis/design/resource_names) of the affected Cloud Run resource\n - **Project full name**: the affected Google Cloud project\n - **Related links** , especially the following fields:\n - **VirusTotal indicator**: link to the VirusTotal analysis page\n3. On the **JSON** tab, note the following fields:\n\n - `resource`:\n - `project_display_name`: the name of the project that contains the asset.\n - `sourceProperties`:\n - `Reverse_Shell_Stdin_Redirection_Dst_Ip`: the remote IP address of the connection\n - `Reverse_Shell_Stdin_Redirection_Dst_Port`: the remote port\n - `Reverse_Shell_Stdin_Redirection_Src_Ip`: the local IP address of the connection\n - `Reverse_Shell_Stdin_Redirection_Src_Port`: the local port\n - `Container_Image_Uri`: the name of the container image being executed.\n4. Look for related findings that occurred at a similar time for the affected\n container. Such findings might indicate that this activity was malicious,\n instead of a failure to follow best practices.\n\n5. Review the settings of the affected container.\n\n6. Check the logs for the affected container.\n\nResearch attack and response methods\n\n1. Review the MITRE ATT\\&CK framework entries for this finding type: [Command and\n Scripting Interpreter](https://attack.mitre.org/techniques/T1059/) and [Ingress Tool Transfer](https://attack.mitre.org/techniques/T1105/).\n2. Check the SHA-256 hash value for the binary flagged as malicious on [VirusTotal](https://www.virustotal.com) by clicking the link in **VirusTotal indicator**. VirusTotal is an Alphabet-owned service that provides context on potentially malicious files, URLs, domains, and IP addresses.\n3. To develop a response plan, combine your investigation results with the MITRE research and VirusTotal analysis.\n\nImplement your response\n\nFor response recommendations, see [Respond to Cloud Run threat\nfindings](/security-command-center/docs/respond-cloud-run-threats).\n\nWhat's next\n\n- Learn [how to work with threat\n findings in Security Command Center](/security-command-center/docs/how-to-investigate-threats).\n- Refer to the [Threat findings index](/security-command-center/docs/threat-findings-index).\n- Learn how to [review a\n finding](/security-command-center/docs/how-to-investigate-threats#reviewing_findings) through the Google Cloud console.\n- Learn about the [services that\n generate threat findings](/security-command-center/docs/concepts-security-sources#threats)."]]
