What exactly is resilience? According to the U.S. National Institute of Standards and Technology, the goal of cyber resilience is to “enable mission or business objectives that depend on cyber resources to be achieved in a contested cyber environment.” In other words, when you’re at odds with cybercriminals and nation-state actors, can you still get your job done? If not, how quickly can you get back up and running?

On April 21st, 2023, AT&T Managed Extended Detection and Response (MXDR) investigated an attempted ransomware attack on one of our clients, a home improvement business. The investigation revealed the attacker used AuKill malware on the client's print server to disable the server's installed EDR solution, SentinelOne, by brute forcing an administrator account and downgrading a driver to a vulnerable version.

AT&T Alien Labs researchers recently discovered a massive campaign of threats delivering a proxy server application to Windows machines. A company is charging for proxy service on traffic that goes through those machines. This is a continuation of research described in our blog on Mac systems turned into proxy exit nodes by AdLoad.

APIs, formally known as application programming interfaces, occupy a significant position in modern software development. They revolutionized how web applications work by facilitating applications, containers, and microservices to exchange data and information smoothly. Developers can link APIs with multiple software or other internal systems that help businesses to interact with their clients and make informed decisions.

The supply chain, already fragile in the USA, is at severe and significant risk of damage by cyberattacks. According to research analyzed by Forbes, supply chain attacks now account for a huge 62% of all commercial attacks, a clear indication of the scale of the challenge faced by the supply chain and the logistics industry as a whole.

In the realm of information security and covert communication, image steganography serves as a powerful technique for hiding sensitive data within innocent-looking images. By embedding secret messages or files within the pixels of an image, steganography enables covert transmission without arousing suspicion. This article aims to delve into the world of image steganography, exploring its principles, techniques, and real-world applications.

AdLoad malware is still infecting Mac systems years after its first appearance in 2017. AdLoad, a package bundler, has been observed delivering a wide range of payloads throughout its existence. During AT&T Alien Labs’ investigation of its most recent payload, it was discovered that the most common component dropped by AdLoad during the past year has been a proxy application turning MacOS AdLoad victims into a giant, residential proxy botnet.

Where do vulnerabilities fit with respect to security standards and guidelines? Was it a coverage issue or an interpretation and implementation issue? Where does a product, environment, organization, or business vertical fail the most in terms of standards requirements? These questions are usually left unanswered because of the gap between standards or regulations on the one hand, and requirements interpretation and implementation, on the other.

Many industries are experiencing rapid growth thanks to the seemingly overnight advancement of new technologies. Artificial intelligence, for example, has swiftly gone from a vague possibility to being a major component in numerous digital systems and processes. Another technology that has somewhat snuck up on us is blockchain.

As we go about our daily lives, whether that be shopping with the family, enjoying dinner at a restaurant, finding our gate at the airport, or even watching TV, we find ourselves more and more often encountering the QR code.
