Don’t take legal advice from a blog post. I was researching the requirement to disclose under UK law and I thought it was interesting so here are some (probably incomplete) notes to explain (my interpretation of) the current UK Law.
A follower sent me a suspicious looking file recently to get my opinion on its behavior and to see if I could pull out a little detail on how it’s working. “Suspicious looking” because at the time, it was getting a zero score on VirusTotal but it appeared to be doing something just a little dodgy in the background. I wanted to post some notes around my quick tear down of the malware show that since so much malware is poorly written and obfuscated you can often do a large amount of analysis of a file’s behaviour in a short period of time.
There’s no doubt that domain accounts with weak passwords can be a serious concern for companies, there are a few ways you can protect yourself against issues like this. The first is to set a domain and local account lockout policy and the second is to enforce password complexity. However if your users are using “Password1” as their password, neither of these steps will protect you.
