Telecom networks are the backbone of the digital economy. They must deliver secure, always-on connectivity at scale, supporting everything from critical national infrastructure to everyday consumer services. But cyber resilience today is no longer defined by uptime alone. It is about the ability to withstand, detect, and respond to highly targeted cyber threats that are designed to exploit the very fabric of telecom environments.

At this time last year, LevelBlue asked its experts to offer up some thoughts on what the coming year, 2025, would bring. So, with a year of hindsight, let’s keep ourselves honest and take a look to see what we got right and where we were a bit off. December 2025.

If you manage security in an enterprise nowadays the cloud likely seems less, like a fixed goal and more like a shifting aim. New cloud accounts emerge quicker than you can assess them. Various teams select providers. SaaS applications are linked with a few clicks and before you know it vital data is transferring through platforms missing from your risk documentation. You are required to maintain the security of all this demonstrate adherence and yet not hinder the business’s progress.

In 2025, security benchmarks showed that over half of publicly disclosed vulnerabilities can bypass WAF protections when rule updates lag behind real-world exploits. Legacy WAFs were built for stable applications and predictable traffic. Today, frequent releases, API-driven architectures, and rapidly evolving attacks expose the limits of manual tuning and after-the-fact validation, leaving protection out of sync with reality.

According to the Indusface State of Application Security Report, SMBs now experience more attacks per application than large enterprises. Each SMB site facing an average of 2.24 million attacks per quarter, driven largely by malicious bot traffic and automated DDoS attempts. Despite this, many SMBs still operate with minimal security controls or legacy technology stacks, making them extremely vulnerable.

The digital storefront never sleeps, but in the first half of 2025, it has faced unprecedented hostility. According to the State of Application Security report 2025 Report, the threat landscape has shifted dramatically. E-commerce has become a primary target, with DDoS incidents in the retail and e-commerce sector spiking by 420%. Perhaps even more concerning is the vector of these attacks: attacks on APIs rose by 104%, with vulnerability exploitation increasing 13-fold.

Top tips is a weekly column where we highlight what’s trending in the tech world and share ways to stay ahead. This week, as the holiday season rolls in and many of us finally take that much-needed break, let’s talk about something equally important: Stepping away from work safely. The holidays are all about resting–logging off and soaking in all the merry feelings. But to truly switch into that much-needed DND mode, it helps to secure your devices before you head out for the holidays.

Data is not just a strategic asset. It’s the lifeblood of your organization. Losing access to any strategic asset can threaten an organization’s viability; without plants and equipment, manufacturers would find it difficult to succeed, and service providers can’t operate without brand recognition. Similarly, without data, your organization could be left in a state of complete and utter paralysis, unable to function or recover.

For decades, enterprise security strategy revolved around a simple assumption: if you could build a strong enough perimeter around your network, everything inside would remain safe. Firewalls, intrusion prevention systems, and VPNs became the bedrock of corporate defenses. The perimeter was the castle wall, and sensitive data lived safely inside.

During routine threat research and monitoring of Chinese-language underground distribution channels, our team identified a malicious RAR archive. Specifically, this archive abuses a critical WinRAR directory traversal vulnerability to achieve arbitrary file write and persistence on Windows systems. To accomplish this, the archive leverages a combination of NTFS Alternate Data Streams (ADS) and directory traversal logic.
