After several weeks of quiet, especially during the Christmas holidays, the Emotet malware bot is up and running again, and it seems stronger and smarter. Several IT security firms have reported seeing phishing emails delivering Emotet via malicious Word documents and even delayed holiday e-greetings. Cyber-attackers using Emotet seem to have used this brief hiatus to improve the malware’s social engineering abilities, with almost a fourth of infected emails being sent as replies to existing email threads. Designed initially as a banking malware, the Emotet Trojan was first identified by security researchers in 2014. The malware delivery botnet spreads itself…

Server Message Block or SMB is a protocol used extensively by windows. It allows windows computers to communicate, locate file servers, locate and communicate with windows networks services and even communicate with other operating systems that understand the SMB protocol.

Versa Security Lab recently analyzed couple of malware samples which arrives on a computer through phishing emails containing documents with embedded link which eventually leads to the download of the malware.

Part 2 of a 3 part series (read part 1 and part 3) Now, my journey.

The Advanced security license provides routing, SD-WAN, NGFW, URL Filtering, AV and NG-IPS [for those who are…

Part 1 of a 3 part series (read part 2 and part 3) Throughout my entire career of 20+ years I predominately have been a work-from-home employee through various roles I have held. As part of #WFH the need for secure and either on-demand or constant connectivity to corporate resources is a hard requirement in order to do my job effectively. Over the last 20+ years how, where and what I need access to have changed quite dramatically. In summary a lot of these resources are now off-net [ e.g. email, SharePoint, Skype, CRM, PRM, collaboration and communication applications [conferencing…

The Wave of Reality

February 14, 2020
After a successful exit with one of the top SD-WAN companies some have asked why I joined Versa Networks. History has shown us that industry disruptions often occur in waves. The first SD-WAN wave of infancy was made up of a number of pure-play startups (including Versa) who entered and helped form the market. The second wave could be referred to as the wave of insanity. The market exploded to nearly 80 vendors many of which were jumping in to “pivot” some or all of their business to SD-WAN. There were quite a few others who simply put an SD-WAN…
