\nThe following is according to my understanding.<\/p>\n
\nI mention, back in my post from January 19, 2026,<\/a> a situation in which an email server detected a phishing attempt as spam. Lately I’ve been busy, so I left an email account unchecked since about a week. The spam box – aka, Junk – had some new arrivals that were almost funny, except for being potentially dangerous.<\/p>\n \nOne said I had received some bitcoin – an obvious scam, since I don’t have a crypto wallet. The other one suggested my password to a hosting service had expired. In each case, I was directed to click a link. (Not happening.)<\/p>\n \nThe email sender, in each case, was the same. That was odd, since the two emails referred to services that would be unrelated. I looked up the domain registration of the sender, which I finally found – that’s another story, for a different post.<\/p>\n \nIn each email, the suggested link to follow was to a domain different from the sender’s. Once again, for both emails, the link leads to the same domain, which starts with a v, then has four more characters, then dot sbs.<\/p>\n I looked up the domain registration behind the suggested link. It contained an error that, to me, seemed obvious. More about that situation, hopefully, in a future post.<\/p>\n \nLikely, the spam checker knew the two emails were scams because of their subject lines. An expiring password warning is typically suspicious; even moreso, a message of receipt of bitcoin. The two unrelated services being referred to from the same email sender, to me, was a big red flag as well.<\/p>\n \nSource:<\/p>\n apache.org: SPAMASSASSIN: WritingRules<\/a><\/p>\nJack of Oracle Tutoring by Jack and Diane,<\/a> Campbell River, BC. \n","protected":false},"excerpt":{"rendered":" Self-tutoring about email and computer security: the tutor mentions some recent arrivals.
