## Step 1<br />The problem is about identifying the potential red flags of a phishing attack. Phishing is a type of cyber attack where attackers attempt to trick individuals into providing sensitive information such as usernames, passwords, and credit card numbers by pretending to be a trustworthy entity in electronic communications.<br /><br />## Step 2<br />The first option, "Messages that contain bad grammar or spelling mistakes", is a common characteristic of phishing emails. These emails are often hastily crafted and may not be proofread, leading to grammatical or spelling errors.<br /><br />## Step 3<br />The second option, "A demand for urgent action - accompanied by a threat", is another common tactic used in phishing attacks. Attackers often create a sense of urgency to prompt immediate action, and may use threats to instill fear and compel the recipient to act without thinking.<br /><br />## Step 4<br />The third option, "An email sent from a public domain address vs. a corporate email account", is also a potential red flag. Legitimate companies typically use their own domain names in their email addresses, not public ones. If an email appears to be from a company but is sent from a public domain address, it could be a sign of a phishing attack.
