5 Signs Your PC Has Been Hacked (and What to do About it)

Though data on computer hacks is often deemed incomplete based on the number of issues that go unreported, it's estimated that up to 2.5 billion online accounts are hacked per year. That boils down to nearly 7 million hacked accounts every day. What's more is that cyber crooks are always seemingly one step ahead of anti-virus and security software, meaning that anything implemented to prevent hacking is often reactive - and not proactive. Yet, it's important to note that there are still several things that users can do to safeguard their computers and their confidential information. But before we get into some prevention basics, let's take a look at five sure-fire signs that your PC has been hacked.

5 Signs Your PC Has Been Hacked (and What to do About it)

5 Signs You've Been Hacked

1. Data Breaches on Websites You Use

Whether it's a data breach of a website that you often use or a phishing attack that has potentially compromised your log-in credentials, data breaches on websites are fairly common. Often times, the browser you're using will alert you if your password has been potentially compromised, and you should take action immediately if it has. If a website that you use has been hacked, you may have to get a new credit card or you may even want to freeze your credit to prevent unauthorized use or identity theft.

2. Someone is Sending Odd Invitations Impersonating You

This is a typical sign of hacker activity on social media networks, as a hacker pretends to be you and either sends invitations to "be a friend" or attempts to gain confidential information from your contacts under your disguise. If a hacker can't gain access to your profile, it's not unusual for them to try to impersonate your profile. If your account has been hacked, be sure to change your password. You may also want to give your friends list a heads up about the issue and then always report the imposter to the social network.

3. You're Receiving Emails About Failed Log-ins

Oftentimes, you'll receive an email if you've attempted to log in to an account from a new device or if you successfully logged in from a new device. It'll tell you not to do anything if you did and then outline the proper steps to take to safeguard your account if the login was not you. To fend off any hackers, just follow the prompts if the login was not you.

4. Your Online Searches are Redirected

Is your browser taking you to webpages you don't want to visit? It's likely a hacker trying to get you to visit either their website or the website of a client so they can attempt to swipe confidential information from you. Resetting your browser settings or deleting any strange toolbars can help.

5. You Notice Strange Internet Browser Toolbars

Notice a new toolbar when you pull up your internet browser? It was probably installed by a hacker who is now trying to manipulate you. Retrace your downloads and make sure you uninstall it or run a security sweep on anything that you're uncertain about.

Prevention is the Best Medicine

When was the last time you've asked yourself, "Have I been hacked?" The best way to prevent becoming a victim of an online hack is to up your game when it comes to recognizing phishing attempts. Don't open any email attachments from senders you're unfamiliar with and be aware of activity that is unusual. Additionally, try to ensure that you're using different passwords for every site you register with and consider using two-factor authentication to make it harder for anyone other than you to gain access to your accounts. Last but not least, be sure to update your computer software when updates become available, as many times these will include the latest security patches.

Online Threat Alerts Security Tips

Pay the safest way

Credit cards are the safest way to pay for online purchases because you can dispute the charges if you never get the goods or services or if the offer was misrepresented. Federal law limits your liability to $50 if someone makes unauthorized charges to your account, and most credit card issuers will remove them completely if you report the problem promptly.

Guard your personal information

In any transaction you conduct, make sure to check with your state or local consumer protection agency and the Better Business Bureau (BBB) to see if the seller, charity, company, or organization is credible. Be especially wary if the entity is unfamiliar to you. Always call the number found on a website’s contact information to make sure the number legitimately belongs to the entity you are dealing with.

Be careful of the information you share

Never give out your codes, passwords or personal information, unless you are sure of who you're dealing with

Know who you’re dealing with

Crooks pretending to be from companies you do business with may call or send an email, claiming they need to verify your personal information. Don’t provide your credit card or bank account number unless you are actually paying for something and know who you are sending payment to. Your social security number should not be necessary unless you are applying for credit. Be especially suspicious if someone claiming to be from a company with whom you have an account asks for information that the business already has.

Check your accounts

Regularly check your account transactions and report any suspicious or unauthorised transactions.

Don’t believe promises of easy money

If someone claims that you can earn money with little or no work, get a loan or credit card even if you have bad credit, or make money on an investment with little or no risk, it’s probably a scam. Oftentimes, offers that seem too good to be true, actually are too good to be true.

Do not open email from people you don’t know

If you are unsure whether an email you received is legitimate, try contacting the sender directly via other means. Do not click on any links in an email unless you are sure it is safe.

Think before you click

If an email or text message looks suspicious, don’t open any attachments or click on the links.

Verify urgent requests or unsolicited emails, messages or phone calls before you respond

If you receive a message or a phone call asking for immediate action and don't know the sender, it could be a phishing message.

Be careful with links and new website addresses

Malicious website addresses may appear almost identical to legitimate sites. Scammers often use a slight variation in spelling or logo to lure you. Malicious links can also come from friends whose email has unknowingly been compromised, so be careful.

Secure your personal information

Before providing any personal information, such as your date of birth, Social Security number, account numbers, and passwords, be sure the website is secure.

Stay informed on the latest cyber threats

Keep yourself up to date on current scams by visiting this website daily.

Use Strong Passwords

Strong passwords are critical to online security.

Keep your software up to date and maintain preventative software programs

Keep all of your software applications up to date on your computers and mobile devices. Install software that provides antivirus, firewall, and email filter services.

Update the operating systems on your electronic devices

Make sure your operating systems (OSs) and applications are up to date on all of your electronic devices. Older and unpatched versions of OSs and software are the target of many hacks. Read the CISA security tip on Understanding Patches and Software Updates for more information.

What if You Got Scammed?

Stop Contact With The Scammer

Hang up the phone. Do not reply to emails, messages, or letters that the scammer sends. Do not make any more payments to the scammer. Beware of additional scammers who may contact you claiming they can help you get your lost money back.

Secure Your Finances

  • Report potentially compromised bank account, credit or debit card information to your financial institution(s) immediately. They may be able to cancel or reverse fraudulent transactions.
  • Notify the three major credit bureaus. They can add a fraud alert to warn potential credit grantors that you may be a victim of identity theft. You may also want to consider placing a free security freeze on your credit report. Doing so prevents lenders and others from accessing your credit report entirely, which will prevent them from extending credit:

Check Your Computer

If your computer was accessed or otherwise affected by a scam, check to make sure that your anti-virus is up-to-date and running and that your system is free of malware and keylogging software. You may also need to seek the help of a computer repair company. Consider utilizing the Better Business Bureau’s website to find a reputable company.

Change Your Account Passwords

Update your bank, credit card, social media, and email account passwords to try to limit further unauthorized access. Make sure to choose strong passwords when changing account passwords.

Report The Scam

Reporting helps protect others. While agencies can’t always track down perpetrators of crimes against scammers, they can utilize the information gathered to record patterns of abuse which may lead to action being taken against a company or industry.

Report your issue to the following agencies based on the nature of the scam:

  • Local Law Enforcement: Consumers are encouraged to report scams to their local police department or sheriff’s office, especially if you lost money or property or had your identity compromised.
  • Federal Trade Commission: Contact the Federal Trade Commission (FTC) at 1-877-FTC-HELP (1-877-382-4357) or use the Online Complaint Assistant to report various types of fraud, including counterfeit checks, lottery or sweepstakes scams, and more.
  • Identitytheft.gov: If someone is using your personal information, like your Social Security, credit card, or bank account number, to open new accounts, make purchases, or get a tax refund, report it at www.identitytheft.gov. This federal government site will also help you create your Identity Theft Report and a personal recovery plan based on your situation. Questions can be directed to 877-ID THEFT.

How To Recognize a Phishing Scam

Scammers use email or text messages to try to steal your passwords, account numbers, or Social Security numbers. If they get that information, they could get access to your email, bank, or other accounts. Or they could sell your information to other scammers. Scammers launch thousands of phishing attacks like these every day — and they’re often successful.

Scammers often update their tactics to keep up with the latest news or trends, but here are some common tactics used in phishing emails or text messages:

Phishing emails and text messages often tell a story to trick you into clicking on a link or opening an attachment. You might get an unexpected email or text message that looks like it’s from a company you know or trust, like a bank or a credit card or utility company. Or maybe it’s from an online payment website or app. The message could be from a scammer, who might

  • say they’ve noticed some suspicious activity or log-in attempts — they haven’t
  • claim there’s a problem with your account or your payment information — there isn’t
  • say you need to confirm some personal or financial information — you don’t
  • include an invoice you don’t recognize — it’s fake
  • want you to click on a link to make a payment — but the link has malware
  • say you’re eligible to register for a government refund — it’s a scam
  • offer a coupon for free stuff — it’s not real
