Calyptix Security Blocks Zero-Day Worm Ahead of Leading Antivirus Makers

September 19, 2006 — CHARLOTTE, NC Internet security firm, Calyptix Security, has successfully identified and blocked a previously unknown and malicious Internet worm from propagating across its network of beta test sites before any of the leading antivirus manufacturers issued an update or removal instructions.

On September 10, 2006, a malicious Internet worm known as WORM_STRATION.BB was detected by the leading antivirus manufacturers. Once discovered, the companies took up to three days to release a "signature-based" update to their clients who remained vulnerable to attack until receiving and activating the fix. The worm was ranked as having high damage and distribution potential by Trend Micro, an industry leader in Internet security. Using the most recent version of its software, version 1.11, released on July 31, 2006, Calyptix Security was immediately able to identify and quarantine the worm so that no damage could be done to the user's workstation or the larger network.

Calyptix Security uses new groundbreaking technology known as DyVax™, which completely eliminates the critical window of vulnerability between virus discovery and deployment of virus signatures. Instead of creating "signature-based" updates, DyVax employs the industry's first dynamic filtering technique to achieve true and unparalleled, zero-day threat protection.

Packaged exclusively with Calyptix Security's AccessEnforcer™ brand product line, DyVax has been deployed to filter email traffic, including POP3, SMTP, and IMAP, and is currently being developed to filter traffic on all major communication channels including Instant Messaging, Web, VoIP, and P2P. In laboratory testing, DyVax has proven more successful than the leading commercial and open source antivirus solutions. To date, customer beta sites have not reported any material problems with false positives.

DyVax was developed and refined by Dr. Yuliang Zheng, a leading international authority in cryptography and network security and Dr. Lawrence Teo, a widely published expert in Internet security and open source technology. DyVax was created as a cornerstone for building a scalable, world-wide Internet Defense Force™.
