7 alarming things a hacker can do when they have your email address
<p><strong>1. Send emails from your address</strong></p>
<p>This is probably the most obvious thing hackers can do with your email address, and it’s a nuisance for sure. Once hackers have your email address, they can use it to target more than just you, sending out email blasts to anyone (maybe even everyone!) in your contact list. As Garry Brownrigg, CEO & Founder of <a href="https://www.quicksilk.com/">QuickSilk</a>, explains, “They can ‘spoof’ an email message with a forged sender address – they don’t even need your password for this.” The things they send can be anything from harmful malware to scams and requests for money; either way, you’d certainly rather they didn’t come from your address.</p>
<p>And although it’s mostly harmless (most savvy internet users are able to catch on when they receive a scam email from a friend’s address), it could still be a problem in some cases. “If a criminal really wanted to hurt someone, they could use this as a way to hook a romantic partner, hack the victim’s employer, get the person in trouble at work, or cause any number of problems in their personal or professional life by impersonating them online,” says Jason Glassberg, co-founder of <a href="https://www.casaba.com/">Casaba Security</a> and former cybersecurity executive at Ernst & Young and Lehman Brothers.</p>
<p><strong>2. Send phishing emails</strong></p>
<p>Since there isn’t a lot that hackers can do with just the email address, they’re not going to stop there. “When a hacker knows your email address, they have half of your confidential information – all they need now is the password,” warns Greg Kelley of <a href="https://www.vestigeltd.com/">Vestige Digital Investigations</a>. They employ a few different methods to access it, the most common being the phishing email. This is an email, in the guise of being a legitimate email from a trusted source, designed to trick you into logging in. “They might create a legitimate-sounding email that appears to be sent from a service such as Amazon, eBay, Paypal or any number of other popular services… Links in phishing emails will always direct the user to a purposefully built website that looks identical to the real service,” explains Ray Walsh, a digital privacy expert at <a href="https://proprivacy.com/">ProPrivacy.com</a>. “However, if people use the login on that fake website, the hacker instantly receives the credential and password for the real account.”</p>
<p>Another way they can do this, ironically, is by sending you an email saying that your account is compromised or has been accessed from a new device, so you need to change your password for security reasons. (You’ve almost definitely had one of those at one point or another!) When you change your password, then your account really is compromised and the hacker has your password. Once hackers have your password, the range of things they can do becomes much greater.</p>
<p><strong>3. Access your online accounts</strong></p>
<p>Nowadays, our emails do double duty as our logins for scores of social media sites, in addition to Google Docs, online retailers, and so on. Internet users also have a very understandable tendency to use the same passwords for all of these accounts. And even if you don’t use the same password, the hacker can click the old ‘forgot password’ button and use the resulting email – which comes to your email address, which they do have the password for – to change the password, and voilà. Your accounts are their accounts, and they have access to anything on them that you do.</p>
<p><strong>4. Access personal information</strong></p>
<p>The things hackers can do with your information seem to be something of a chain reaction. Once a hacker has access to your online accounts, just think about all of the information that is right at their fingertips. Allan Buxton, Director of Forensics at SecureForensics, sums it up: “At a minimum, a search on Facebook can get a public name and, unless privacy protections are in place, the names of friends and possibly pictures,” he says. “Throw that email address into LinkedIn, and they’ll know where you work, who your colleagues are, your responsibilities, plus everywhere you worked or went to school. That’s more than enough to start some real-world stalking. That’s just two sites – we haven’t talked about political views, travel or favourite places they might glean from Twitter or Instagram.”</p>
<p>Glassberg admits that such ‘real-world stalking’ is rare, sure, but anything is possible in an era where people document nearly everything online.</p>
<p><strong>5. Steal financial information</strong></p>
<p>Things start to get really problematic if hackers are able to find your credit or debit card information – which, more likely than not, you’ve sent via email at one point or another. Your online bank accounts can also be a major target for hackers, especially if you use your email address as a login for those, too. And, needless to say, once a hacker has access to those, your money is in serious jeopardy. “This is one of the biggest risks you’ll face from an email hack,” Glassberg says. “Once [hackers] have the email, it’s easy to reset the bank account and begin issuing transactions.” In addition to potentially being devastating of your finances, this can also hurt your credit score, as <a href="https://www.beenverified.com/">BeenVerified</a>’s Chief Communications Officer Justin Lavelle explains: “Cybercriminals can use your credit card details, open bank accounts in your name, and take out loans. It will likely ruin your credit card’s rating and your credit report will take a hit.”</p>
<p><strong>6. Blackmail you</strong></p>
<p>As if things weren’t scary enough, hackers can use your personal info to ruin, or threaten to ruin, your reputation. This is fairly rare, but it can happen, especially if a hacker finds something that the user wouldn’t want to be seen publicly. “[Hackers] can use this access to spy on you and review your most personal emails,” says Daniel Smith, head of security research at <a href="https://www.radware.com/">Radware</a>. “This kind of information could easily be used to blackmail/extort the victim.”</p>
<p><strong>7. Steal your identity</strong></p>
<p>This is definitely a worst-case scenario, but “once the hacker has your personally identifiable information, they can steal your identity,” Brownrigg warns. With information like your tax file number and credit card info, identity theft can sadly be well within reach for hackers. So, if you start noticing signs someone just stole your identity, consider that your email address may have been compromised.</p>
<p><strong>How you can stay safe from hackers</strong></p>
<p>Hopefully, though, you won’t have to encounter any of these problems, and there are some measures you can take to keep your information safe. Avoid using your verbatim email address as a login for other sites, and make sure that your password is strong and difficult to guess. You should also change those passwords every couple of months or so for maximum security. Glassberg also recommends securing your email account with two-factor authentication. This “[requires] a one-time code to be entered alongside the password in order to gain access to the email account,” he told RD. “In most cases, the code will be texted to the person’s phone, but there are also apps you can use, like Google Authenticator.”</p>
<p>And, of course, just use common sense. Don’t share information or type in your email password on public WiFi networks, and be smart about the information you share over email.</p>
<p><strong>What to do if you think you’ve been hacked</strong></p>
<p>Starting to notice some strange online activity? There are a couple of ways you can try to get ahead before it gets too bad. If you hear about spam emails being sent from your address, change your password immediately. You should also tell your contacts so that they know to ignore anything coming from you. Finally, Lavelle offers some other suggestions: “Change your email settings to the highest privacy setting, scan your computer for malware and viruses, and be sure your browsers are updated,” he says.</p>
