One of the key features in VMRay Analyzer 2.0 is the built-in reputation engine that identifies known malicious or known benign files in milliseconds. The addition of the reputation engine gives Incident Responders and Malware Analysts a powerful “One-Two” combination of rapid threat detection and detailed analysis of malware behavior. To illustrate the benefits of […]Read More "[Video] Analyzing a Malicious Microsoft Word Document"
In boxing, the “One-Two” combination is an essential component of a fighter’s arsenal. A left jab followed by a right cross is one the most effective combinations a fighter can unleash on his opponent. In the fight against malware, it’s just as important for Malware Analysts and Incident Responders to have a “One-Two” combination consisting […]Read More "Malware Detection and Analysis: Delivering a Knockout Blow to Malware"
We have started to see malware authors use embedded Visual Basic (VBA) macros in many unconventional file types to attack hosts. In response to this trend, VMRay Analyzer V 2.0 now supports the analysis of Microsoft Access and Microsoft Publisher files. Support for analysis of new sample types means greater coverage of an attack surface […]Read More "Analyzing Malware Embedded in MS Publisher Files"

This past week, a new Ransomware variant called Spora was spotted in the wild. Currently, Spora only targets Russian-speaking users. What’s interesting about this Ransomware is that its payment site is so well designed, one could think they are running a legitimate business. The dropper for Spora is basically an HTML application (.hta) that executes VBScript. […]Read More "Spora Ransomware Dropper Uses HTA to Infect System"
A new code injection technique is effective in bypassing most analysis and detection methods. Code injection has been a favorite technique of malware authors for many years. Injecting malicious code into an otherwise-benign process is an effective way of masking malware from anti-virus and sandbox detection. It is used to bypass end-host firewalls and to evade sandbox monitoring. […]Read More "AtomBombing Evasion and Detection"
There have been several variants of the Hancitor malware family seen in the wild over the past several months. Recently, Carbon Black, a VMRay integration partner, provided an in-depth analysis of a specific strain of the Hancitor Malware family that uses a Microsoft calendar identifier to deliver malware to unsuspecting users. We did a full analysis in […]Read More "Hancitor Uses Microsoft Word to Deliver Malware"
Sharing is caring. Nowhere is this more true than for defenders that need to be able to quickly and seamlessly share critical information about malware and the attackers behind them. In the jargon of our industry that means using TIPs (Threat Intelligence Platforms) to ingest, export and correlate IOCs (Indicators of Compromise) and the TTPs (Tactics, […]Read More "Threat intelligence sharing with MISP and VMRay"
This is our final post in a series on sandbox evasion techniques used by malware today. We started with a primer, and then covered the two other main categories of sandbox evasion techniques: Sandbox Detection: Detecting the presence of a sandbox (and only showing benign behavior patterns on detection) Exploiting Sandbox Gaps: Exploiting weaknesses or […]Read More "Sandbox Evasion Techniques – Part 4"
