Second Look®: Advanced Linux Malware Detection & Investigation

Linux is everywhere in the modern enterprise—in cloud deployments, web infrastructure, and many business-critical back-end services. And it is increasingly attacked—at mass scale by cybercriminals and in targeted operations by motivated attackers.

The "Shellshock" bash bug was just the latest in a series of events this year that have shown that Linux systems are vulnerable to a number of different exploit vectors, and are being actively targeted and compromised. The "Windigo" and "Mayhem" malware campaigns have affected tens of thousands of Linux servers, and are ongoing. The "Evanescent Bat" case demonstrated a high level of sophistication in a targeted attack. Vulnerabilities due to the "Shellshock" bug are leading to many thousands more systems being infected with these and other strains of malware. The attacks are highly differentiated and constantly evolving.

Second Look can be particularly useful for detecting artifacts of malware in memory such as [code] injection and system call manipulation...

Promoting verifiable Linux-based IT infrastructure

Combating modern cyber adversaries with backward-looking signatures (indicators of their past activity) is a losing proposition. When an attack hasn't yet been uncovered by researchers and the malware involved hasn't yet been analyzed, signature-based detection isn't possible. Malware is virtually guaranteed an extended dwell time when you rely on signatures to detect it.

Malware detection based on verifying code and data in memory is a far more effective approach. With Second Look, you can ensure that Linux systems are running exactly the software they're supposed to be running, and nothing more. The power of memory forensics uncovers stealth malware and alerts on unknown or unexpectedly modified software. Second Look provides assurance that the programs and libraries in memory on Linux servers and workstations, from the kernel to system services and applications, are of known origin and have not been tampered with. Integrity verification detects both known and never-seen-before rootkits, backdoors, and other unauthorized processes.

Architected for scalable deployment and ease of integration

Whether you are investigating an incident now, or want to have the best shot at catching intrusions going foward: if you run Linux, Second Look is your tool. Use Second Look to minimize attacker dwell time, ascertain the scope of a compromise, gauge the success of remediation, and ensure that Linux systems throughout the enterprise are running the correct software load.

Our customers include the IT security teams of major corporations, firms which have investigated numerous high-profile security breaches, and government agencies responsible for protecting extraordinarily sensitive data. We support all Linux distributions, with extensive reference data collections to support the analysis and verification of systems running Amazon Linux, CentOS, Debian, Fedora, Oracle Linux, Red Hat Enterprise Linux (RHEL), and Ubuntu.

Tabs within Second Look provide easy access to the extracted information associated with each process...

See Second Look in action!

The demo video below shows Second Look using live memory analysis of a remote target system to detect an unauthorized process running there. After the process is hidden with a rootkit, not only can Second Look still see the suspect process, it also produces additional alerts on the rootkit itself.


Product Editions

The Incident Response edition provides memory acquisition and analysis tools to help you get right to the root of the problem when you're investigating a suspect system.

The Enterprise Security edition has all the features of the IR edition, plus provides memory forensics of remote systems that scales across large deployments for instant investigation and automated scanning and alerting. It produces highly-actionable alerts that can easily feed into any security event management system.
