The question of whether you need antivirus (AV) for Windows devices is always up for debate. The advancements and new technology have made the operating system (OS) more secure and reliable. Nevertheless, the effectiveness and lethality of cyber threats have increased as well. And every year, millions of Windows users fall victim to various digital perils.

In cybersecurity, where information is both an asset and a potential target, various techniques are used to secure data and communications. One such covert art is steganography, which hides information within seemingly innocuous files to avoid detection. This article dives into the fascinating world of steganography, its history, techniques, and applications in the digital age.

Cybercriminals live on the cutting edge of technology, and nothing fits the label more than artificial intelligence. It helps them design sophisticated, evolving malware, pose as higher-ups, and even successfully imitate biometrics like one’s voice. The use of AI in cyber security has developed as a natural response to these new and unpredictable challenges. How are cyber security experts using artificial intelligence to thwart the bad guys?

PCI DSS (Payment Card Industry Data Security Standard) is a set of security controls created to ensure all companies that accept, process, store or transmit credit card data maintain an audit-ready environment. Version 4.0 was published in March 2022; organizations required to be compliant have until March 31, 2024, when compliance must be complete.

Application programming interface (API) security is critical for retailers increasingly reliant on cloud technology. However, they also open potential gateways for cyber threats, making robust security protocols essential to protect sensitive data and maintain customer trust. The complexity of retail systems, which often involve numerous third-party integrations, can create multiple points of vulnerability.

While most end users are well-acquainted with the dangers of traditional phishing attacks, such as those delivered via email or other media, a large proportion are likely unaware that Microsoft Teams chats could be a phishing vector. Most Teams activity is intra-organizational, but Microsoft enables External Access by default, which allows members of one organization to add users outside the organization to their Teams chats.

Network segmentation, software patching, and continual threats monitoring are key cybersecurity best practices for Industrial Control Systems (ICS). Although ICSs significantly improve health and safety by automating dangerous tasks, facilitating remote monitoring and control, and activating safety protocols in the case of emergency, they’re increasingly exposed to cybersecurity threats.

In the ever-evolving cybersecurity landscape, 2023 witnessed a dramatic surge in the sophistication of cyber threats and malware. AT&T Cybersecurity Alien Labs reviewed the big events of 2023 and how malware morphed this year to try new ways to breach and wreak havoc. This year's events kept cybersecurity experts on their toes, from expanding malware variants to introducing new threat actors and attack techniques.

We’re pleased to announce the availability of the 2023 AT&T Cybersecurity Insights Report: Focus on Finance. The report examines the edge ecosystem, surveying finance IT leaders from around the world, and provides benchmarks for assessing your edge computing plans. This is the 12th edition of our vendor-neutral and forward-looking report. Last year’s focus on finance report documented how we secure the data, applications, and endpoints that rely on edge computing (get the 2022 report).
