A security researcher Eric Romang has found a Internet Explorer 0-day exploit in the wild of CVE-2012-4969 where a malicious flash file uses Adobe Flash Player to conduct a "heap spray" to bypass the ASLR (Address Space Layout Randomization) protection in Windows.
This could allow the installation of a backdoor allowing remote access to a fully patched Windows PC.
Detecting this Threat using RSA NetWitness:
- Customers who wish to alert on this Malware may create a custom feed to tag sessions that have the following filenames:
Protect.html (This filename may produce false positives as seen in Google advanced search of: allinurl: Protect.html)
Please refer to Primus Article A59743 for information on creating custom feeds
There's a diagram which shows the relationship between the files.
- At present only one IP address has been detected as supplying the payload. A custom feed or App Rule could be used to alert on accesses to IP: 188.8.131.52
- Future 3rd party feeds may include compromised websites that have this Malware.
- Spectrum should detect 111.exe if it is transferred over the network (if the VirusTotal service is enabled through the Spectrum Cloud)
