One day I went to a client site to perform internal penetration test to emulate the insider threat. This testing was designed to help this client understand the damage a rogue employee or an intruder who gained physical access to the network could do. The site that I was visiting was a storefront and had public WiFi. I told the store staff who I was there to meet, and while I waited for the client to become available I connected to the public WiFi just to have a look.
Prior to arriving, I’d received a list of the internal systems that were in scope for testing. So while I waited, I decided to try to scan the store’s systems just to cross this attack vector off my list. Certainly, this client wouldn’t have bridged his public and private networks – this should be just a quick check.
I was startled to see that I was able to see the cash registers and back office server at the location. After this I started to wonder…I know that the locations are connected to the corporate LAN via point-to-point VPN, I couldn’t see beyond this store could I? I went back to my scope document and found the IP addresses for the corporate headquarters. I kicked off another scan and sure enough, I was able to see this company’s domain controller at their corporate headquarters from the public WiFi of one of their many stores. Taking advantage of the lack of segmentation, I was able to launch attacks on the corporate LAN from the comfort of a table, on the patio of this location, all while drinking the soda that they served me.

Security is a team game. If your organization values both independence and security, perhaps we should become partners.
The increased need for cyber security has become a common enterprise priority across the globe. However, industry requirements for effective cyber risk management are as distinct as the individual entities under fire. Enterprises and government organizations need more than an off-the-shelf audit to provide an effective threat assessment. They need industry- and organization-specific insights, tools and processes to protect digital assets and ensure compliance.
Coalfire can help cloud service providers prioritize the cyber risks to the company, and find the right cyber risk management and compliance efforts that keeps customer data secure, and helps differentiate products.
“Success” at a government entity looks different than at a commercial organization. Create cybersecurity solutions to support your mission goals with a team that understands your unique requirements.
The financial services industry was built upon security and privacy. As cyber-attacks become more sophisticated, a strong vault and a guard at the door won’t offer any protection against phishing, DDoS attacks and IT infrastructure breaches.
The continuum of care is a concept involving an integrated system of care that guides and tracks patients over time through a comprehensive array of health services spanning all levels of care. Interoperability is the central idea to this care continuum making it possible to have the right information at the right time for the right people to make the right decisions.
Maintaining network and data security in any large organization is a major challenge for information systems departments. However, in the higher education environment, the protection of IT assets and sensitive information must be balanced with the need for ‘openness’ and academic freedom; making this a more difficult and complex task.
When it comes to cyber threats, the hospitality industry is not a friendly place. Hotels and resorts have proven to be a favorite target for cyber criminals who are looking for high transaction volume, large databases and low barriers to entry.
The payments industry is undergoing rapid changes and unfortunately, an increasing risk for data breaches. Cyber criminals are growing increasingly businesslike, and payments leaders need to move quickly to cover their cyber risk.
The food and beverage industry is under attack from cyber criminals intent on stealing payment information. The food and beverage industry makes up the highest percentage of breach investigations, at nearly 73 percent, according to Visa.
The global retail industry has become the top target for cyber terrorists, and the impact of this onslaught has been staggering to merchants. To secure the complex IT infrastructure of a retail environment, merchants must embrace enterprise-wide cyber risk management practices that reduces risk, minimizes costs and provides security to their customers and their bottom line.
Private enterprises serving government and state agencies need to be upheld to the same information management practices and standards as the organizations they serve. Coalfire has over 16 years of experience helping companies navigate increasing complex governance and risk standards for public institutions and their IT vendors.
Technology innovations are enabling new methods for corporations and governments to operate and driving changes in consumer behavior. The companies delivering these technology products are facilitating business transformation that provides new operating models, increased efficiency and engagement with consumers as businesses seek a competitive advantage.
Cybersecurity has entered the list of the top five concerns for U.S. electric utilities, and with good reason. According to the Department of Homeland Security, attacks on the utilities industry are rising "at an alarming rate."
