General Details SolarWinds is a publicly traded company worth $5.4B dollars that developing IT infrastructure management software products for small and medium-sized enterprises.

The malware known as SUNBURST potentially allows an attacker to compromise the server on which the Orion products run. The manner in which SUNBURST malware was used against its victims resulted in it being labelled a “supply chain attack,” a technique in which an adversary uses malware to disrupt a companies ability to produce or deliver it’s products to customers.

IT Security and Stocks

Futuristic Graphic logo of two people eating a cookie.

Session cookies constitute one of the main attack targets against client authentication on the Web. To counter these attacks, modern web browsers implement native cookie protection mechanisms based on the HttpOnly and Secure flags. … Our analysis of the Alexa-ranked top 1000 popular websites gives clear evidence that such risks are far from remote, as the HttpOnly and Secure flags appear as yet to be largely ignored by web developers. – CookiExt: Patching the Browser Against Session Hijacking, Journal of Computer Security (2015).   Summary of Session-hijacking attacks When you login into a website, the web-server creates a “session” to identify your identity by sending the client browser a session cookie.

To summarize, the browser bar is considered the only reliable security indicator to validate the authenticity of the website. Looking at the browser URL bar at the top of your browser, and checking that the domain contained in the URL matches the domain of the site you expect to be visiting. If it says “” or “” you should be able to reliably tell that you are on the correct website.
