Berlin city administration has confirmed data theft following a ransomware attack by the Rhysida group. Rhysida claims to have exfiltrated over 5TB of data, including personal information and credentials, and is attempting to extort the city. Berlin authorities have stated they will not pay the ransom ^[11]^[29].
Manchester Airports Group is the subject of a data breach claim by the extortion group FulcrumSec, which alleges theft of over 80GB of data and plans to leak it online ^[27]^[31].

The China-linked cyber espionage group Fire Ant has expanded operations to compromise Cisco IOS XR routers, using them to steal credentials and blind security logs. Fire Ant has also been observed creating unexplained GRE tunnel interfaces on compromised routers, turning them into spying platforms ^[7]^[9].

Trends, Tools, or Tactics of Interest

There is increased use of AI-powered tools and agents in cyberattacks, as demonstrated by Aurora ransomware’s use of Cursor and the need for security teams to treat AI agents as highly privileged identities following incidents involving Hugging Face and Claude ^[5]^[23]^[24].
Offensive security toolkits such as Praetorian are consolidating established workflows into portable Go-based tools, supporting direct pipelines and shared SDKs for red team operations ^[19].
JSCeal, a stealer targeting cryptocurrency applications, is being delivered as compiled V8 bytecode executed by a bundled Node.js runtime, representing a novel malware delivery technique ^[30].

Regulatory or Policy Developments Affecting the Security Industry

A judge has ruled that the Pentagon’s measures against Anthropic, which labeled the company as a supply chain risk, were illegal and baseless. This decision is part of an ongoing legal dispute between Anthropic and the US government ^[28].
The US Department of Justice has corrected a previous statement regarding Chinese cyberattacks, clarifying that US agencies were targets but not confirmed victims ^[8].
