You may have heard about the recent phishing scam that targeted Google Docs users. People received emails with what looked almost exactly like shared Google Docs, tricking them into granting access to a not-particularly-nice piece of software. From there, the attack could spread to other inboxes.
It's far from the first time users have been attacked through their inboxes and it certainly won't be the last—sending emails is an easy and low-cost way to fool people into letting their guard down. With that in mind, we're here to make sure your inbox is tightly buttoned up against phishing attempts, malicious attachments, and more. While we can't guarantee your safety, these precautions will certainly minimize your risk.
Your email of choice, whether Gmail's web portal or a desktop program like Outlook, already comes with a decent set of security tools. For example, it can snag suspicious emails and automatically toss them into your spam folder. To help out your email client, report spam whenever you find it, which will make it easier for the program to spot something untoward next time.
Be wary of any email asking you to click a link, especially if it comes out of the blue without any context—and particularly if it comes from someone you don't know. Phishing emails can appear to come from trusted contacts, but they often arrive from bizarre-sounding email addresses. To double-check the identity of the sender, and pull up the full header information for suspicious emails. To do this in Gmail, for instance, open the drop-down menu for the message then choose Show original.
Unfortunately, even a message that comes from a known contact with the correct email address isn't necessarily safe. As we've said, if one of your friends or family members is hit by a phishing attack, then their valid email address can be used to send you a dangerous message. This means that context is key. Were you expecting a message with a link in it? Does the message make sense? If you're unsure, it's worth a quick phone call or message over social media to check the email is what it purports to be. Ask the same questions before opening attachments: Were you expecting them? What's the context?
Hackers are getting better with their craft, but spelling errors and awkward layouts are still tell-tale signs of emails you should steer clear of (the spelling errors are often intentionally left in to evade spam detectors). Another check you can do is to hover over any links or attachments, which might bring up a preview, and alert you to potential problems before you click.
If you do click on a link, check that the URL in your browser's address bar is the one you were expecting, and look for the green padlock symbol that shows the site is secure and trusted. If a sign-in page pops up—or if you're in any doubt—open a new window and directly type in the URL of the site you think you should be going to, rather than following any embedded links.
Browser extensions can also help protect you from phishing attacks. Gmail Sender Icons makes it easier to identify where a message has come from, while Google's own Password Alert warns you if you're about to enter your Google account password into a site that isn't made by Google. Both extensions are well worth installing if you have a Gmail account and use the Chrome browser. Not a Gmail or Chrome user? Look for add-ons for your own email client.
Take safety beyond your inbox
Protecting against shady links and malicious attachments goes beyond your inbox. For example, most modern-day browsers come with built-in security measures designed to thwart phishing attempts. For best results, make sure your browser of choice is kept up to date at all times (thankfully, browsers usually update automatically).
Keep your operating system and your antivirus package up to date as well. If you're using an antivirus program on Windows, then it probably features extra security measures to protect against dangerous attachments that want to do your computer harm, as well as fraudulent links that lead your browser somewhere it shouldn't go.
You should also take precautions when using public Wi-Fi, because unsecured networks give hackers more elbow room when it comes to spoofing sites and stealing your information. If you want to be as safe as possible when using the web away from home, we'd recommend sticking to sites that don't deal in sensitive information and installing a VPN package to encrypt any data you do send.
Remember standard email security measures
As we've mentioned before, it's a good idea to regularly check the plug-ins and add-ons connected to your email inbox. This will reveal any third-party programs that have access to your Gmail or Yahoo or Outlook account. This is actually the recommended clean-up method for the phishing attack we referred to at the start of this article—removing the app's permissions means it will no longer have control of your inbox.
The place to find these add-on tools varies depending on your setup. For Gmail, head to your Google account page and click the link labelled Connected apps & sites. After that, select Manage apps and get rid of anything you don't use regularly or simply don't recognize. To be clear, many of these add-ons are useful and perfectly safe. But from a security point of view, it's a good idea to keep the number of these tools to a minimum.
Finally, stay informed: Keep an eye on the tech headlines to track the new types of attack that appear on a regular basis. While Google, Microsoft, and other companies usually deal with the latest dangers quite quickly, you're better off hearing about a dangerous scam before it hits your inbox rather than after.
