Are you ready, as an organisation?

As COVID-19 restrictions are gradually relaxed, businesses, workers and other duty holders must work together to adapt and promote safe work practices.

COVID portal is designed to provide organisations with a compliant and protective approach to prevent introduction of COVID-19 to your workplace.

Care and protection for all employees.

The care and protection of your employees, the continuity of business operations and of your brand are paramount. COVID Portal incorporates a daily baseline 2-Stage Work Status Check consisting of an employee Health Declaration and Thermal Scanning. This may be directed towards your entire workforce or to specific groups within your employee base who require more attention:

  • Your Executive team
  • Critical and Essential employees
  • Medically vulnerable employees

COVID Portal provides reassurance that your employees are screened daily to attend work or can be tailored with a customised offering to specific groups within your business.

Hashcat Compressed Wordlist High Quality

zstd -o wordlist.zst wordlist.txt

While there isn't a single "academic paper" exclusively dedicated to the specific feature of compressed wordlists in Hashcat, the functionality is a core technical feature documented in Hashcat's official source code and discussed in professional recovery contexts. Technical Overview

Use zcat or 7z -so to stream compressed text without extracting it.

Rather than generic compression, Hashcat offers its own highly optimized and markov files. These are not wordlists but probabilistic tables generated from training data. While not compressed wordlists per se, they represent a complementary approach: use a compressed traditional wordlist for targeted attacks, and a .hcstat2 file for brute-force/mask attacks based on character distribution. Advanced users often combine both: a small, highly curated compressed wordlist (e.g., company-specific-words.gz ) fed through a rule engine, alongside a Markov-generated mask.

For truly massive wordlists, the compression ratio can be astonishing. One Hashcat user reported successfully working with a 2.5TB uncompressed wordlist that was compressed to just 250GB using GZIP. While the initial load time was approximately three hours on a mechanical hard drive, once the dictionary cache was built, subsequent operations proceeded normally. This demonstrates that while compressed wordlists add some overhead during initialization, the storage savings often justify the wait.
