Dokumen ini menjelaskan jenis temuan ancaman di Security Command Center. Temuan ancaman dibuat oleh
pendeteksi ancaman saat mendeteksi
potensi ancaman di resource cloud Anda. Untuk daftar lengkap temuan ancaman yang tersedia, lihat Indeks temuan ancaman.
Ringkasan
Model machine learning mengidentifikasi kode Python yang dieksekusi sebagai berbahaya. Penyerang
dapat menggunakan Python untuk mentransfer alat dan menjalankan perintah tanpa biner. Menjaga container Anda tetap tidak dapat diubah adalah praktik yang penting.
Penggunaan skrip untuk mentransfer alat meniru teknik penyerang dalam transfer alat masuk dan dapat menyebabkan deteksi yang tidak diinginkan.
Buka temuan Execution: Malicious Python executed seperti yang diarahkan dalam Meninjau temuan.
Tinjau detail di tab Ringkasan dan JSON.
Di tab Summary, tinjau informasi di bagian berikut:
Apa yang terdeteksi, terutama kolom berikut:
Biner program: detail tentang interpreter yang memanggil skrip
Script: jalur absolut nama skrip di disk; atribut ini hanya muncul untuk skrip yang ditulis ke disk, bukan untuk eksekusi skrip literal—misalnya, python3 -c
Argumen: argumen yang diberikan saat memanggil skrip
Resource yang terpengaruh, terutama kolom berikut:
Nama lengkap resource: nama lengkap resource
dari resource Cloud Run yang terpengaruh
Link terkait, terutama kolom berikut:
Indikator VirusTotal: link ke halaman analisis VirusTotal
Di tab JSON, perhatikan kolom berikut:
finding:
processes:
script:
contents: konten skrip yang dieksekusi, yang mungkin dipangkas
karena alasan performa; hal ini dapat membantu penyelidikan Anda
sha256: hash SHA-256 dari script.contents
resource:
project_display_name: nama project yang berisi aset.
Cari temuan terkait yang terjadi pada waktu yang serupa untuk penampung yang terpengaruh. Misalnya, jika skrip menjatuhkan biner, periksa temuan yang terkait dengan biner tersebut. Temuan tersebut mungkin menunjukkan bahwa aktivitas ini bersifat berbahaya, bukan karena tidak mengikuti praktik terbaik.
Periksa nilai hash SHA-256 untuk file biner yang ditandai sebagai berbahaya di
VirusTotal dengan mengklik link di
Indikator VirusTotal. VirusTotal adalah layanan milik Alphabet yang memberikan konteks tentang file, URL, domain, dan alamat IP yang berpotensi berbahaya.
Untuk mengembangkan rencana respons, gabungkan hasil penyelidikan Anda dengan riset MITRE dan analisis 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 machine learning model identified executed Python code as malicious. Attackers\ncan use Python to transfer tools and execute commands without binaries. Keeping\nyour containers immutable is an important\n[practice](https://kubernetes.io/docs/concepts/containers/#container-images).\nUsing scripts to transfer tools mimics the attacker technique of [ingress tool\ntransfer](https://attack.mitre.org/techniques/T1105/) and can result in unwanted\ndetections.\n\nDetection service\n\n[Cloud Run Threat Detection](/security-command-center/docs/cloud-run-threat-detection-overview)\n\nHow to respond\n\nTo respond to this finding, do the following:\n\nReview finding details\n\n1. Open the `Execution: Malicious Python executed` 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**: details about the interpreter that invoked the script\n - **Script** : absolute path of the name of the script on disk; this attribute only appears for scripts written to disk, not for literal script execution---for example, `python3 -c`\n - **Arguments**: the arguments provided when invoking the script\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 - **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 - `finding`:\n - `processes`:\n - `script`:\n - `contents`: contents of the executed script, which might be truncated for performance reasons; this can aid in your investigation\n - `sha256`: the SHA-256 hash of `script.contents`\n - `resource`:\n - `project_display_name`: the name of the project that contains the asset.\n4. Look for related findings that occurred at a similar time for the affected\n container. For example, if the script drops a binary, check for findings\n related to the binary. Such findings might indicate that this activity was\n malicious, 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 Scripting\n 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)."]]
