Businesses are now targeted by advanced persistent threat actors looking for proprietary data, financially motivated threat actors looking to steal sensitive data and conduct extortion attacks, and hacktivist groups that aim to disrupt business operations.

Many of these attacks see initial access to internal networks and accounts gained via email. Credential phishing and malware phishing attempts serve a similar purpose and allow threat actors to obtain initial access to allow them to achieve their objectives, whether that is to gain persistent access for espionage purposes, to steal data, use ransomware, or wipe devices.

Email techniques such as phishing and spear phishing for credential theft or the use of malspam emails for delivering malware can be sophisticated and difficult for end users to detect. Further, advances in artificial intelligence have led to generative AI solutions that are capable of producing flawless phishing emails and generating novel social engineering techniques to trick users into taking the required actions – following a link, disclosing sensitive data, or downloading and executing malware.

Spam filters and secure email gateways have long protected businesses against these threats, but increasingly sophisticated techniques are now used that can bypass the protections of traditional email security solutions and reach end users. To combat these threats email security solutions have had to adapt. Cutting-edge email security solutions such as SpamTitan Email Security have AI and machine learning capabilities that are capable of detecting advanced and sophisticated attacks, in addition to DMARC, SPK, and DKIM reputation checks, and blacklists of known malicious IP addresses and domains.

One of the biggest threats comes from malware, either attached to emails or downloaded from URLs that are linked in email messages. For many years, antivirus engines have been effective at detecting and blocking malware threats, and while they still provide a degree of protection, AV engines are signature-based. When a new malware sample is detected, a unique signature is detected and added to a malware definition list. When a new file is received, it will be checked against all known signatures. If that signature is detected, the file will be quarantined or deleted.

New malware samples, which are being released at an incredible rate, will not be detected as malicious, as their signature has yet to be created and added to the list. These files will therefore not be detected as malicious and will be delivered to inboxes. To protect against this, advanced email security solutions use email sandboxing.

Email sandboxing involves creating an isolated, protected environment for analyzing suspicious emails. If front-end checks are passed, the email is sent to the sandbox for deep analysis. The sandbox is a protected environment where no harm can be caused, and files can be safely analyzed for malicious behavior.

TitanHQ’s Email Sandbox Service

In response to growing threats, TitanHQ added a next-generation email sandbox to its SpamTitan Email Security solution in 2019 to better protect users against malware, spear-phishing, advanced persistent threats (APTs), and to provide security teams with insights into new threats.

TitanHQ’s email sandbox service incorporates award-winning machine learning and behavioral analysis technologies, allowing security teams to safely detonate suspicious files in a secure environment that mirrors production endpoints. Malicious actors are tricked into thinking their malicious payloads have reached their intended target, and the malicious activities are detected. The sandbox analyzes documents, spreadsheets, application files, and executable files, and can detect malware, including polymorphic malware, and other sophisticated threats that have been developed for use in undetectable targeted attacks.

The TitanHQ email sandbox service leverages purpose-built, advanced machine learning algorithms, decoys and anti-evasion techniques, anti-exploit, and aggressive behavior analysis, and all results are checked against an extensive array of online repositories. The analysis takes from a few seconds to a few minutes, and if a malicious file is detected, the results will be uploaded to a cloud threat intelligence service and all users will be protected. If that threat is detected on any device globally, it will not need to be sent to the sandbox again and will be instantly neutralized.

SpamTitan email sandbox service greatly increases the detection rate of elusive threats in the pre-execution stage, including APTs, targeted attacks, evasion techniques, obfuscated malware, custom malware, and ransomware, allows security teams to quickly integrate advanced emulation-based malware analysis, and protects against a rapidly evolving threat landscape.

You can put the SpamTitan email sandbox service to the test today by signing up for a 100% free trial and instantly start protecting your business with sandbox technology.
