Security | Threat Detection | Cyberattacks | DevSecOps | Compliance

UK railway cybersecurity spending is accelerating as ransomware, insider incidents, and IT/OT convergence expose the sector's growing attack surface. Part one of CYJAX's rail security series looks at the numbers behind the trend and what they mean for UK operators.

From a fast-scaling ransomware operator to a Russian state-sponsored espionage group now experimenting with LLM-powered malware, and a data extortion collective that has weathered arrests without slowing down, these three threat actors span the full spectrum of financially and geopolitically motivated cybercrime. CYJAX breaks down what each group does, why they matter, and what security teams should know.

The CLOUD Act compels US-incorporated vendors to hand over data on request, regardless of where it's hosted. Here's why vendor jurisdiction matters for CTI.

The CSRB has cleared the House of Commons and Royal Assent is expected before the end of 2026. CYJAX breaks down scope, reporting timelines, penalties, and how threat intelligence underpins compliance.

Security teams are not short of data; they are short of intelligence they can trust. This piece explains how raw threat data becomes trusted, actionable intelligence through validation, attribution, and enrichment, and why the distinction matters as false positives and threat volumes continue to rise.

The operational risk in threat intelligence is not missing a data source, it is misclassifying what that data means. This piece breaks down where the process fails, why threat actor attribution and dark web intelligence assessment require human analyst judgement, and how validated, attributed intelligence shortens breach lifecycles for CISOs and security teams.

From a fast-growing ransomware affiliate network to a politically motivated DDoS collective and a prolific data extortion group, these three threat actors represent distinct but pressing risks across sectors and regions. CYJAX breaks down what each group does, why they matter, and what security teams should know.

Cyber reporting to the board has a consistency problem: updates arrive regularly but rarely deliver the forward-looking intelligence executives need to act. This piece breaks down why the disconnect exists, how it affects CEOs, CFOs, and CISOs differently, and what decision-ready threat intelligence should actually look like at board level.

SaaS-only platforms are betting everything on automation. But when the threat landscape demands judgement, data volume alone is not the answer. For years, a certain category of threat intelligence vendor has sold the same idea: feed your data into our platform, let the AI process it, and your security team will have everything they need. It is a compelling proposition, particularly for organisations under pressure to demonstrate coverage without expanding headcount.

Detect compromised devices before attackers act. CYJAX’s new alerting identifies stealer malware infections and exposed credentials in near real time. CYJAX today announced the launch of Compromised Device Alerting, a new capability designed to help organisations identify compromised devices within their environment before attackers can act on stolen credentials.
