The Beers with Talos B team (that’s Hazel, Bill, Joe and Dave) break down (sometimes in the literal sense) the 2025 Talos Year in Review which is available now at blog.talosintelligence.com/2025yearinreview

The team dives into the biggest cybersecurity trends of the year, including:

·       The rapid weaponization of new vulnerabilities

·       Why identity abuse showed up everywhere 

·       Ransomware trends

·       A rise in APT investigations

·       What defenders should prioritize heading into the year ahead

Before that, we discuss the cyber activity tied to the situation in the Middle East (full details on our blog https://blog.talosintelligence.com/talos-developing-situation-in-the-middle-east).

There’s also an alarming amount of discussion about glutes. And gravy. Listen here:

The 2025 Talos Year in Review is now available to view online.

The pace and scale of adversary activity in 2025 placed sustained pressure on security teams across industries. As with each annual report, our goal at Talos is to provide the security community with a clear analysis of the tactics, techniques, and procedures that shaped adversary operations, and to help organizations prioritize the actions that reduce exposure and strengthen defenses.

What defined 2025

Three themes emerged consistently across Talos’ threat research, telemetry, and incident response engagements:

1. Exploitation at both extremes

New large-scale vulnerabilities were operationalized almost immediately, but adversaries also continued to exploit CVEs that have been exposed for years. This rapid operationalization of new vulnerabilities reflects a rise in automated exploit development, public proof-of-concept code, and mature adversary coordination.

React2Shell, released in December, ranked first by year’s end only three weeks after disclosure, while a vulnerability disclosed 12 years ago ranked seventh. That range tells a story about organizational technical debt: Long-standing exposure continues to be reliably and successfully exploited.

2. The architecture of trust

In 2025, adversaries focused on the systems that manage authentication, authorization, and device trust.

Attackers who gained access through compromised credentials stealthily extended that access through internal phishing and abuse of identity controls within network infrastructure. Control of identity often meant control of the environment.

3. Targeting centralized systems for more leverage

Threat actors targeted centralized infrastructure, management platforms, and shared frameworks to expand the impact of a single compromise.

Approximately 25% of the vulnerabilities in the Top 100 targeted list affected widely used frameworks and libraries that are embedded deep within the software stack. Because these components underpin applications and network appliances across vendors, a single CVE can create mass exploitation potential across industries. Compromising these shared foundations enabled lateral movement across environments.
