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).

The exponential rise of ransomware attacks in recent times has become a critical concern for organizations across various industries. Ransomware, a malicious software that encrypts data and demands a ransom for its release, can wreak havoc on an organization's operations, finances, and reputation. This comprehensive guide delves into the intricate landscape of ransomware, exploring sophisticated attack vectors, common vulnerabilities, and providing detailed strategies for prevention.

Organizations face a constant challenge to balance transparency and security in today's rapidly evolving digital landscape. One emerging concept that has gained traction in recent years is the practice of "self-doxxing." This seemingly counterintuitive term refers to the deliberate and controlled sharing of an organization's information, often sensitive, to enhance transparency, accountability, and trust.

This is part three of a three-part series written by AT&T Cybersecurity evangelist Theresa Lanowitz. It’s intended to be future-looking, provocative, and encourage discussion. The author wants to assure you that no generative AI was used in any part of this blog.

With the democratization of computing comes attack surface expansion. According to Gartner, 91% of businesses are engaged in some form of digital initiative, and 87% of senior business leaders say digitalization is a priority. 89% of all companies have already adopted a digital-first business strategy or are planning to do so.

Do you recall how tentatively and maybe naively we approached the year 2000, otherwise known as Y2K? We stressed over two bytes in COBOL programs and regression tested every line of code to ensure our systems were ready to go at midnight on January 1, 2000. The clock struck 12, and the world breathed a collective sigh of relief – we survived the predicted digital disaster.

Artificial intelligence (AI) has seamlessly woven itself into the fabric of our digital landscape, revolutionizing industries from healthcare to finance. As AI applications proliferate, the shadow of privacy concerns looms large. The convergence of AI and privacy gives rise to a complex interplay where innovative technologies and individual privacy rights collide.

BlackCat is and has been one of the more prolific malware strains in recent years. Believed to be the successor of REvil, which has links to operators in Russia, it first was observed in the wild back in 2021, according to researchers. BlackCat is written in the Rust language, which offers better performance and efficiencies than other languages previously used. BlackCat is indiscriminate in how it targets its victims, which range from healthcare to entertainment industries.

In the ever-evolving landscape of cybersecurity threats, social engineering remains a potent and insidious method employed by cybercriminals. Unlike traditional hacking techniques that exploit software vulnerabilities, social engineering manipulates human psychology to gain unauthorized access to sensitive information.
