Email spammers can manipulate email headers, making it difficult to trace the originating internet service provider (ISP) and mail server. Reputable ISPs sometimes face temporary blocks due to spam complaints, which can affect legitimate emails. This issue is not limited to Yahoo; other email providers also implement similar blocking measures. Spammers have developed techniques to bypass these restrictions. Gmail defines email spoofing as messages that falsely appear to come from a legitimate source, referring to incoming spoofed emails as forging. To combat this, Gmail employs Domain-based Message Authentication, Reporting, and Conformance (DMARC) to help prevent spam. The ongoing battle between cyber attackers and defenders mirrors historical efforts to combat theft and fraud, highlighting the persistent challenges in achieving foolproof security measures.

Gmail supports Domain-based Message Authentication, Reporting, and Conformance (DMARC) as a way to prevent this type of spam.

The war between cyber attackers and cyber defenders is endless. Compare it with the war to stop money theft and fraud. Thousands of years of human experience has not produced a foolproof way of preventing that.
 

Thread 'How far will we let AI control us?'

I’ve spent nearly my entire life online, and witnessed AI become integrated into our lives. It’s clear that AI is apart of us now whether we like it or not, unless your a anti tech cabin lover. AI has some form of control over your life. But what I’ve seen very recently is that people are loosing their ingenuity and deciding to use AI. I feel as if it’ll bleed into STEM which is kinda has already and, every idea or thought could become fully reliant on AI. Yeah AI makes life easier but at a...
