Week 7: Google Begins Using Quantum Encryption

 The Hacker News reported, in February, that Google's cloud service Key Management Systems would begin using quantum encryption for its digital signature. This is the future of a technological process we have been studying this week, digital encryption. A long standing problem in not just cyber work but communication in general. It is often pointed to Roman times that encryption first came about. A code called the "Caesar Cypher" was nothing more than a means of shifting the alphabet--the exact shift would be called the key. Today we use modern standard of encryption for most of our digital communication such as AES-256 and RSA. These methods utilize large prime number multiplication and remainder math to create a key which is virtually impossible to crack with a classic computer. However, the advancement of mathematical equations (specifically Shor's algorithm) and quantum computing have lead to the research of "post quantum encryption" PQE. This is what Google aim to get a head of today.

Week 1: HTB

      Hack the Box is a wonderful cite for anyone trying to gain both knowledge and hands-on experience in Cyber Security and red/blue team activities. The only downside is the amount of time you have to spend to "get good". HtB is an internationally recognized cite and proving yourself in its various "boxes" will also look very good on a resume.      There are two main ways I would suggest using HtB. One, start in their academy and complete modules and skills on different tools like "nmap", "nc", "sql injections", etc. Once you feel pretty comfertable on your abilities to manage a red team job try out hacking the box. There are hundreds of different puzzles called "boxes" where you will need to use your new skills to exploit the machine. It is incredibly educational and I cannot recommend enough. Charlie

Week 5: Confidentiality and Privacy: do we need new privacy laws?

I am taking mostly historical information here on the various laws enacted between the 1970's and 2000's which have governed the use of Private Identifiable Information by the federal government and private companies in the US. Most of these laws: like HIPAA and the GLBA are incredibly relevant today to safeguarding our most personal data from people who would do use harm. For a long time this meant keep our data out of the hands of hackers and thieves and while that is still relevant today, there is seemingly a large gap between the US's privacy laws concerning private companies, and those of Europe.  The stark difference is in the EU's General Data Protection Regulation (GDPR) and California's Consumer Privacy Act (CCPA) which were adopted in 2018 and 2020 respectively. The GDPR has a government oversight board by which all private companies must abide by. This creates an active participation in holding private companies responsible for consumer data. It is the jo...

Week 10: Spear Finishing in Turkey with LNK Files

  Phishing has taken on a new dimension in the last few years: using LNK files (Microsoft specific files that can provide a shortcut from one file to another). The purpose of these files is specifically to open PowerShell and run a command to download more malware from an online server. The group Patchwork has been associated with the recent LNK spear phishing attacks against defense contractors in Turkey specifically. Since 2009 the malware group has been suspected of associating with the State of India making them a formattable threat.
