VirusTotal += SecureAge

We welcome SecureAge APEX scanner to VirusTotal. In the words of the company:

“SecureAge APEX is an anti-malware scanning engine powered by artificial intelligence, designed to extend the detection capabilities of the SecureAge SecureAPlus endpoint protection platform (EPP). The APEX engine provides next-generation endpoint detection as part of the SecureAPlus layered approach to security which includes Application Control & Application Whitelisting, multi-cloud anti-virus, fileless attack protection and more. To deal with advanced threats like zero-day malware, the APEX engine goes beyond traditional scanners by reliably identifying unseen and mutated malware types and variants from day one of their release. The APEX engine that runs in VirusTotal targets Windows PE files; with integration into the VirusTotal ecosystem, SecureAge looks forward to further enhancing APEX's capabilities, and above that, adding value to VirusTotal's cybersecurity services.”

SecureAge has expressed its commitment to follow the recommendations of AMTSO and, in compliance with our policy, facilitates this review by AV-Comparatives, an AMTSO-member tester.

VirusTotal MultiSandbox += Yoroi: Yomi sandbox

We are excited to welcome Yomi: The Malware Hunter from Yoroi to the mutisandbox project. This brings VirusTotal upl to seven integrated sandboxes, in addition to VT’s own sandboxes for Windows, MacOS, and Android.


In their own words:
Yomi engine implements a multi-analysis approach able to exploit both static analysis and behavioral analysis, providing ad hoc analysis path for each kind of files. The static analysis section includes document and macro code extraction, imports, dependencies and trust chain analysis. The behavioral detection engine is weaponized to recognize suspicious actions the malware silently does, giving a powerful insight on command and control, exfiltration and lateral movement activities over the network, including encrypted channels. Each analysis is reported in an intuitive aggregated view to spot interesting patterns at a glance.


Some recent samples on VirusTotal with reports from Yoroi:


To see the full details click on the “Full report” within the behavior tab.

Interesting features


 Executed commands
Within the Yomi Hunter report, additional information on executed commands can be seen. In this case, we see obfuscated powershell commands being run.


To search other behaviour reports for the string “zgohmskxd” we can use the behavior_processes:zgohmskxd search query to find another sample with the same variable name. Check out the other search modifiers that can be used to find similar samples.


Mutexes

Within the Additional information tab, we can also find the mutexes used by the sample under analysis. behaviour:AversSucksForever

 To search other sandbox behavior reports with the same string we can search

behavior:AversSucksForever


Mitre ATT&CK™ tab

On the MITRE ATT&CK™ tab you can see how the specific behaviour is behavior is tagged

Relationships

With the emotet sample we can see the SMB and HTTP traffic. Next you can click on the relationships tab to see other related IP Addresses, Domains, URLs and files.

 You can visually see these relationships from within VirusTotal Graph:

VirusTotal Multisandbox += NSFOCUS POMA

We are pleased to announce that the multisandbox project has partnered with NSFOCUS POMA. This brings VirusTotal up to six integrated sandboxes. The NSFOCUS sandbox gives us insight into the behaviour of samples that run on Windows 7 and XP SP3.

In their own words:

NSFOCUS POMA, as an integral part of the NSFOCUS Threat Intelligence (NTI) system, is a cloud‐based malware analysis engine built by the NSFOCUS Security Lab. It can take various types of files and perform both static and dynamic analysis on them to detect potentially malicious behavior, and produce analytic reports in many formats (including STIX). This service can help a user to protect his environment from various threats, such as 0‐day attacks, advanced persistent threats (APTs), ransomware, botnets, cryptocurrency mining and other malware.


We are very honored and proud to bring such values to the VirusTotal users and community.

Here are a few examples:

You can find the sandbox behaviour reports on the behavior tab.

Threat Summary

At the top of the detailed report, right away we can see a summary of the detection.

Threat Detail


Within the threat detail section we can see the behavior in both Windows XP SP3 and Windows 7 SP1 ordered by risk, most important at the top.






Registry actions:
Within the behaviour report we can see an interesting UUID


Using  a behavior search in VT Intelligence, we can find other samples that also use this same UUID




Connecting the dots

In the sample we can see the relationship with the IP address 185[.]45[.]252[.]36







Within VTGraph we can visually see the relationships between this sample, the IP address, domains and URLS that we know about
