This week in cybersecurity, we’re seeing major developments across government policy, corporate security, and new hacking tactics. A newly discovered attack method exploits trusted system files to bypass security defenses, while Hewlett Packard Enterprise (HPE) disclosed a breach linked to a Russian-backed Office 365 compromise. Meanwhile, Canada is investing $38 million in its cybersecurity infrastructure, and Mastercard is teaming up with VikingCloud to provide cybersecurity solutions for SMBs.

Additionally, a staggering 28 million devices have been hijacked in a new cyber attack, and the FBI has issued an urgent warning about a phishing campaign using fake texts and messages. Finally, Ukraine has officially launched a project to bolster its cyber defense capabilities amid ongoing cyber warfare threats.

Here’s what you need to know.

In this week's Weekly Round-Up, AI vulnerabilities are being exposed and law enforcement is striking back against underground hacking forums. This week, we’re looking at a massive data breach at China-based AI firm DeepSeek, a malware campaign targeting Android devices, a critical vulnerability in Cisco Webex, and much more.

With cyberattacks targeting everything from social media platforms to enterprise collaboration tools, the risks to businesses and individuals continue to grow. Understanding these threats is the first step in protecting against them.

Here’s everything you need to know from this week in cybersecurity.

Cybersecurity developments this week highlight the growing complexity of cyber threats, regulatory shifts, and emerging security risks that businesses must navigate. Canada is launching a national cybersecurity strategy, Microsoft vulnerabilities are actively exploited, and AI security concerns are prompting government action. Meanwhile, major data breaches continue to expose millions of records, raising alarms across industries.

Let’s explore the most important cybersecurity updates of the week.

Artificial intelligence is no longer just a tool for automation—it’s evolving into an autonomous agent capable of perceiving, reasoning, and acting without human intervention. In cybersecurity, this shift is enabling faster threat detection, improved incident response, and proactive defense mechanisms that were previously impossible at scale.

Agentic AI refers to systems that go beyond simple automation. These AI-driven solutions are not just following pre-defined rules; they are actively learning from new threats, making independent decisions, and executing security actions autonomously.

With cyberattacks becoming more sophisticated and attackers leveraging AI to automate their attacks, security teams must leverage agentic AI to stay ahead. Below, we explore ten critical applications of agentic AI in cybersecurity, showcasing how these technologies are reshaping digital defense strategies.

This week, cybersecurity threats have once again made headlines, with major incidents affecting financial institutions, healthcare systems, cloud storage platforms, and even maritime operations. A data breach at TD Bank exposed sensitive customer information, while a critical vulnerability in Alibaba Cloud put business data at risk. Meanwhile, a backdoor in Contec patient monitors has raised concerns about the security of medical devices.

On a regulatory front, the U.S. Coast Guard has implemented new cybersecurity mandates for the maritime industry, signaling a growing focus on securing critical infrastructure. At the same time, businesses worldwide are facing increasing cyber risks, as seen in breaches affecting Kenya’s Companies Registry.

With cybercriminals constantly refining their tactics, organizations must stay ahead of the latest threats. Here’s a deep dive into this week’s most pressing cybersecurity developments.

Every January 28th, Data Privacy Day reminds us of the crucial role privacy plays in our digital lives. In a world where technology permeates every facet of existence, safeguarding personal and organizational data isn’t just about compliance—it’s about trust, security, and responsibility.

Today, let’s reflect on the most pressing questions individuals and organizations should ask themselves about data privacy. Answering these questions honestly can help uncover gaps and guide actionable steps to strengthen data protection.
