Endpoint Detection

Joe Sandbox Mail Discontinued

Joe Sandbox Mail 1.9 has been discontinued and is replaced by Joe Sandbox Detect. Joe Sandbox Detect covers the same functionalities as Joe Sandbox Mail plus some great additional features.

Joe Sandbox Detect in a Nutshell

Joe Security offers an Endpoint Protection called Joe Sandbox Detect. Joe Sandbox Detect is a powerful endpoint detection tool with three main functionalities:

  • Automatic analysis of suspicious files with Joe Sandbox Cloud or Joe Sandbox On-Premise
  • Manual analysis of suspicious e-Mails, attachments and files with Joe Sandbox Cloud and Joe Sandbox On-Premise
  • Alert the security team (SOC, CERT, CIRT) as well as the user about malicious detection

Automatic Analysis of suspicious Files

Joe Sandbox Detect monitors the following browsers and e-Mail applications:

  • Google Chrome
  • Microsoft Internet Explorer
  • Mozilla Firefox
  • Microsoft Edge
  • Microsoft Outlook
  • Mozilla Thunderbird

If one of those applications creates a suspicious file e.g. through an exploit or user interaction Joe Sandbox Detect uploads the file to Joe Sandbox Cloud or Joe Sandbox On-Premise:


The following files are considered suspicious:

  • Exe, dll, sys, doc, docx, docm, dot, dotm, rtf, xls, xlsx, xlsm, xltx, xlt, xltm, ppt, pptx, mht, hta, cmd, scf, lnk, pot, potx, pptm, bat, pif, sct, com, cpl, js, jse, vbs, vbe, jar, rar, zip, iso, 7z, bzip, bzip2, tar, gzip, lzh, chm, msi and sfx

Joe Sandbox analyzes the file and informs the security team (CERT, CIRT, SOC etc) as well as the user.

Manual Analysis of interesting Files

In addition, users can manually check an e-Mail or file for malware. To do this, select the appropriate e-Mail / file and drag it to the analysis area.


Since the analysis is very comprehensive, it can take up to 6 minutes. Once the analysis is complete the security team as well as the user are alerted:


Joe Sandbox Detect classifies your submission into clean, suspicious and malicious:



The suspicious verdict can also have the attribute expert knowledge needed. In that case Joe Sandbox is not sure about the detection. An experienced malware analyst should have a look at the analysis report.

If the user clicks on Open Analysis Report Joe Sandbox Detect will download and show the PDF analysis report.


Joe Sandbox Detect directly connects to your Joe Sandbox Cloud or Joe Sandbox On-Premise web user account. Therefore you can access all analysis via the Joe Sandbox web interface. You can also download all IOCs, detailed analysis report etc.

Create custom Alerts

Alerts are e-Mail messages about a malicious or suspicious detection which are send by Joe Sandbox to the security team. In order to create an alert login into the Joe Sandbox Web interface. Then click on your account and then Alerts. Next click Create New and fill the fields according to the screenshot below:


The XPATH filter /analysis/signaturedetections/strategy[@name=’empiric’]/detection[text()=’MAL’] triggers on all malicious detections. /analysis/signaturedetections/strategy[@name=’empiric’]/detection[text()=’SUS’] on all suspicious analyses. You can extend the filter to only trigger on Microsoft Office documents or PDF. To do so have a look at the Filter Guide which you find on account - Filters. Once saved Joe Sandbox will send e-Mail alerts to all e-Mail addresses specified.

Data encryption

Joe Sandbox Detect offers the option to encrypt all the analysis data permanently. See the option “ENCRYPTCONFIDENTIALDATA” in the Installation section below.

Data encryption means that:

  • All the analysis data is encrypted on our server at the end of an analysis.
  • The encryption key is exclusively stored on the endpoint, i.e. nobody else can decrypt these files except for the endpoint user. Even Joe Security staff cannot decrypt the files!
  • If you download a report in Joe Sandbox Detect, it is decrypted on the fly, so the password does not have to be entered explicitly.
  • We use AES-256 encryption with a random 256-bit password for each analysis. You can pre-define a password for each endpoint which is used to encrypt all analyses instead, so that your SOC has the possibility to decrypt the analyses as well.
  • Please note that meta information (i.e. sample hash, filename, detection status) is not encrypted.

View Analysis

Right click on Joe Sandbox Detect tray icon in your task bar. Then select Show Analysis:


The Analysis Overview will open. You can download the report from there, and also copy the password to the clipboard to be able to decrypt further data (if encryption is used).

Security disclaimer


Joe Sandbox Detect detects malicious e-mails, attachments and files, however does not delete or remove them. You are responsible for deleting and removing malicious files and e-mails. Also be aware that Joe Sandbox is not perfect. An e-mail, attachment or file detected as clean does not warrant that there is no maliciousness!
