Foreign powers, ransomware gangs and AI threats are driving a surge in incidents affecting British businesses and government systems, [the British Intelligence Agency] GCHQ has warned.

Britain has suffered double the number of “nationally significant” cyberattacks in recent months compared with the year before, according to GCHQ.

Richard Horne, chief executive of the National Cyber Security Centre (NCSC), said that the GCHQ unit has managed 200 cyberattacks since September, which includes “twice as many nationally significant incidents as the same period last year”.

...

Referencing the recent attacks on Marks & Spencer, Co-op and Harrods, Horne told the CyberUK conference in Manchester that “the threat picture is diverse and dramatic” and called ransomware “a persistent threat”.

...

Rod Latham, director of cybersecurity at the Department for Science, Innovation and Technology, said: “Our statistics indicate that four in ten businesses are attacked in a year, three in ten charities — millions of cybercrimes in a year.”

...

Horne called China “the pacing threat in the cyber-realm” and “a cause for profound and profuse concern”.

...

On Russia he said that “we see a direct connection between Russian cyberattacks and physical threats to our security” and warned that amid talks on Ukraine, “it is almost certain that Russia will continue its wider cyber espionage activity … against Ukraine and supporting countries”.

...

Today we released Vulnerability-Lookup 2.9.0 with new features, enhancements, and bug fixes.

What's New

Adversarial Techniques from MITRE EMB3D

The Adversarial Techniques from MITRE EMB3D are now integrated into Vulnerability-Lookup as a new source and are correlated with existing security advisories.

This feature was contributed by Piotr Kaminski during the last Hack.lu hackathon. (#129)

Global CVE Allocation System (GCVE)

GCVE identifiers are now supported in HTML templates and URL parameters,
thanks to the GCVE Python client.
These identifiers can now be used when disclosing a new vulnerability as part of the Coordinated Vulnerability Disclosure (CVD) process, in alignment with NIS 2 requirements. (8bb3d84, 58c394a)

Trustworthy Level for Members

Members of a Vulnerability-Lookup instance now have a dynamically calculated
trustworthy level based on profile completeness and verification.
Members affiliated with FIRST.org or European CSIRTs (CNW) are automatically
trusted for operations that would otherwise require administrator approval
(e.g., creating comments).

Changes

• New API endpoint for MITRE EMB3D. (c0d6b44)
• Improved the vulnerability disclosure page. (ccfb6b1)
• Added page arguments to the vulnerability/last endpoint. (ce75a7a)
• Notification emails now include a random signoff. (#119)
• Various graphical enhancements. (0878a31)

Fixes

• Fixed editing of notifications for Organization/Product. (#124)

Changelog

• Under the new rules, tenders will award bonus scores to offers that deploy cybersecurity technologies manufactured in Italy, EU member states, NATO countries, or other like-minded partners.
• The legislation follows high‑profile incidents of Chinese technology infiltrating sensitive sites, ranging from surveillance cameras in courts and ministries to thermoscanners at the prime minister’s office, and the award of customs‑scanner contracts to China’s Nuctech.
• Products include: video surveillance and access‑control systems (including baggage and cargo scanners); VPN‑capable digital networking products, routers, modems (including satellite types), and switches; firewalls, intrusion detection and prevention systems; network storage and backup solutions; cloud services; drone‑control software
• Preference is extended to suppliers from the EU, NATO members, and “like‑minded” countries with collaboration agreements—namely Australia, South Korea, Japan, Israel, New Zealand, and Switzerland.
• The government retains authority to update the list of covered categories and beneficiary states, based on recommendations from public administrations and intelligence agencies, ensuring the framework evolves alongside emerging security needs.

Blogged a bit about Kidflix login credentials and tried to make some basic password analysis. Originally the bulk of the post was written in the beginning of April, but I forgot and it was just sitting there in my drafts directory.

[This is an op-ed by Tin Pak, visiting academic at the National Defense University and a researcher at the Institute for National Defense and Security Research in Taiwan, and Chen Yu-cheng, an associate professor at the National Defense University.

The term “assassin’s mace” originates from Chinese folklore, describing a concealed weapon used by a weaker hero to defeat a stronger adversary with an unexpected strike. In more general military parlance, the concept refers to an asymmetric capability that targets a critical vulnerability of an adversary. China has found its modern equivalent of the assassin’s mace with its high-altitude electromagnetic pulse (HEMP) weapons, which are nuclear warheads detonated at a high altitude, emitting intense electromagnetic radiation capable of disabling and destroying electronics.

An assassin’s mace weapon possesses two essential characteristics: strategic surprise and the ability to neutralize a core dependency. HEMP weapons fit both criteria. In nanoseconds, a single HEMP detonation at an altitude between 20km and 50km can disable electronic infrastructure across large swathes of Taiwan. There would be little warning, as the Chinese People’s Liberation Army (PLA) fields DF-17 hypersonic missiles, capable of delivering a HEMP warhead above Taiwan in a matter of minutes.

HEMPs strike at the foundation of modern society, its electronic systems. Every critical infrastructure uses electronics, from telecommunications, hospitals, energy production and distribution facilities, and even water purification systems.

The Global CVE (GCVE) allocation system is a new, decentralized approach to vulnerability identification and numbering, designed to improve flexibility, scalability, and autonomy for participating entities.

This client can be integrated into software such as Vulnerability-Lookup to provide core GCVE functionalities by adhering to the Best Current Practices.
It can also be used as a standalone command-line tool.

Examples of usage

As a command line tool

First install the gcve client:

$ python -m pip install --user pipx
$ python -m pipx ensurepath

$ pipx install gcve
  installed package gcve 0.6.0, installed using Python 3.13.0
  These apps are now globally available
    - gcve
done! ✨ 🌟 ✨
