Fixing Your Weakest Link: Your Employees

Fixing Your Weakest Link: Your Employees

You can have every piece of security hardware in the books: firewall, backup disaster recovery device, anti-virus; but your employees will still be the biggest vulnerability in your organization when it comes to phishing attacks. How do you mitigate as much risk as possible?
 

  1. Create and Strictly Enforce a Password Policy: Passwords should be complex, randomly generated, and replaced regularly. In order to test the strength of your password go to this site. (This is a perfectly safe service sponsored by a password protection platform that tells you how long it would take a hacker to decode your password.) When creating a password policy, bear in mind that the most prevalent attacks are Dictionary attacks. Most people utilize real words for their passwords. Hackers will typically try all words before trying a brute force attack. Instead of words, use a combination of letters, numbers, and symbols. The longer the password, the stronger it is. While it’s difficult to remember passwords across different platforms, try not to repeat passwords. This will protect all other accounts in the event of a breach on one of your accounts.
  2. Train and Test Your Employees Regularly: Educate your employees on how they can spot a phishing attack. Then, utilize penetration testing (a safe phishing attack orchestrated by your IT company to see how employees respond) to see how well they do. If employees fall for phishing attempts, send them through training again. We recommend doing this on a quarterly basis to ensure that your employees stay on their toes, and you always provide education on the latest attacks.
  3. Create a Bring Your Own Device Policy and Protect all Mobile Phones: You can safeguard as much as humanly possible on your network, but your employees are all walking in with a cell phone. Are they allowed to get emails on these phones? What about gaining access to the network remotely? Cell phones create a big black hole in security without proper mobile device management and mobile security.
  4. Perform Software Updates Regularly: Make sure that your software is up-to-date with all the latest security patches. Holding off on updates means that you’re leaving yourself open to vulnerabilities that have been discovered and addressed.
  5. Invest in Security: Security is not something for cost savings. Home-based hardware is not sufficient, and you at the very least need a quality firewall and backup device. Invest in your employee’s training, ongoing security updates, and maintaining a full crisis/breach plan.

There are two things that aren’t going away in any business, employees and security threats. Make sure that you’ve taken care of everything you can to avoid falling victim.

How To Spot A Phishing Attack

How To Spot A Phishing Attack

Would you know if you were the subject of a phishing attack? Many people claim that they’d be able to tell right away if they received an email from an illegitimate source. If that were the case, there wouldn’t be 1.5 million new phishing sites every month, a 65% increase in attacks in the last year, and hackers would have moved on to their next idea for swindling people out of their identities and money.  How do you spot a phishing attack and avoid falling victim yourself?

Look for these red flags:

  1. Sender Email Address: Always check to make sure that the email address is legitimate. Amateur hackers will send things from Gmail or Hotmail accounts and hope you don’t notice. More sophisticated hackers will closely mimic an actual email domain, like amazonprime.com rather than amazon.com. Double check the email address before responding, clicking, or opening, even if the from name appears correct.
  2. Discrepancies in Writing Format: If the attack is coming from overseas, you’re likely to notice some small issues in writing format, like writing a date as 4th April, 2018 rather than April 4, 2018. While this is subtle, it should be a red flag.
  3. Grammar Issues: We all fall victim to the occasional typo, but if you receive an email riddled with grammar and spelling mistakes, consider the source. It’s likely a hacker, especially if the email supposedly comes from a major organization.
  4. Sender Name: This one is also difficult to track, but phishing emails will typically close with a very generic name to avoid raising suspicion. You should recognize the people that send you emails, or at the very least, clearly understand their role at the organization.
  5. Link Destination: Before you click on any link in an email, hover over it. The destination URL should pop up. Check out the domain name of this URL. Similar to the sender email address, make sure that this address is legitimate before clicking.
  6. Attachments: Is it realistic to expect an attachment from this sender? Rule of thumb, don’t open any attachment you don’t expect to receive, whether it’s a Zip file, PDF or otherwise. The payload for a ransomware attack often hides inside.
  7. Email Design: A cooky font like Comic Sans should immediately raise red flags if you don’t clearly recognize the sender.
  8. Links to Verify Information: Never, ever click on a link to verify information. Instead, if you think the information does need updating, go directly to the website. Type in your email and password, and update your information from the Account tab. Always go directly to the source.
  9. Odd Logo Use: Hackers try their best to mimic the site’s look and feel. Oftentimes, they get very close; but they won’t be perfect. If something feels off, it probably is.

While there is no fool-proof method for avoiding falling victim to a phishing attack, knowing how to spot likely culprits is one step in the right direction. We’ll cover other protective measures to reduce your risk of falling victim to phishing attacks in our next blog.

What Is Phishing & How Are Hackers Using It?

What Is Phishing & How Are Hackers Using It?

While the number of people falling for sending personal information to the crown prince of Nigeria in hopes of receiving his promised wealth and riches seems to be dropping, phishing remains a major issue. In fact, the number of phishing campaigns pursued by hackers around the world increased 65% in the last year.

What exactly is phishing? Hackers mimic the emails, forms, and websites of legitimate companies in an effort to lure people into providing their private, personal information, like credit cards numbers, social security information, account logins, and personal identifiers. The victim typically doesn’t realize they’ve been compromised until long after the event, and oftentimes only after their identify or finances are affected. In the past, an attack was carried out relatively quickly. As soon as the victim gave up their information, the hacker moved in and stole money from the compromised bank account. Today, it’s often more lucrative for hackers to sell that information on the Dark Web, resulting in longer-lasting, even more devastating attacks

3 Types Of Phishing Attacks

Spear phishing

Phishing attempts directed at specific individuals or companies have been termed spear phishing. Attackers may gather personal information about their target to increase their probability of success. This technique is by far the most successful on the Internet today, accounting for 91% of attacks.

Threat Group-4127 used spear phishing tactics to target email accounts linked to Hillary Clinton‘s 2016 presidential campaign. They attacked more than 1,800 Google accounts and implemented accounts-google.com domain to threaten targeted users.

Clone phishing

Clone phishing is a type of phishing attack whereby a legitimate, and previously delivered, email containing an attachment or link has had its content and recipient address(es) taken and used to create an almost identical or cloned email. The attachment or link within the email is replaced with a malicious version and then sent from an email address spoofed to appear to come from the original sender. It may claim to be a resend of the original or an updated version to the original. This technique could be used to pivot (indirectly) from a previously infected machine and gain a foothold on another machine, by exploiting the social trust associated with the inferred connection due to both parties receiving the original email.

Whaling

Several phishing attacks have been directed specifically at senior executives and other high-profile targets within businesses, and the term whaling has been coined for these kinds of attacks. In the case of whaling, the masquerading web page/email will take a more serious executive-level form. The content will be crafted to target an upper manager and the person’s role in the company. The content of a whaling attack email is often written as a legal subpoena, customer complaint, or executive issue. Whaling scam emails are designed to masquerade as a critical business email, sent from a legitimate business authority. The content is meant to be tailored for upper management, and usually involves some kind of falsified company-wide concern. Whaling phishers have also forged official-looking FBI subpoena emails, and claimed that the manager needs to click a link and install special software to view the subpoena.

Have you ever gotten an email from your bank or medical office asking you to update your information online or confirm your username and password? Maybe a suspicious email from your boss asking you to execute some wire transfer. That is most likely a spear phishing attempt, and you’re among the 76% of businesses that were victims of a phishing attack in the last year.

Method of Delivery

Phishing scams are not always received through email and hackers are getting trickier and trickier with their preferred method of execution. Last year, in 2017, officials caught on to attacks using SMS texting (smishing)Voice phishing (vishing) or social engineering, a method in which users can be encouraged to click on various kinds of unexpected content for a variety of technical and social reasons.

Ransomware: The Consequence

Phishing is the most widely used method for spreading ransomware, and has increased significantly since the birth of major ransomware viruses like Petya and Wannacry. Anyone can become a victim of phishing, and, in turn, ransomware attacks; however, hackers have begun targeting organizations that are more likely to pay the ransoms. Small businesses, education, government, and healthcare often, unfortunately, don’t have valid data backups, so they are unable to roll back to a pre-ransomed version of their data. Instead, they have to pay their way out or cease to exist. Outside of ransom costs, victims of phishing campaigns are often branded as untrustworthy, and many of their customers turn to their competitors, resulting in even greater financial loss.

Why are effective phishing campaigns so rampant despite public awareness from media coverage?

  1. Volume: There are nearly 5 million new phishing sites created every month, according to Webroot Threat Report. There are now even Phishing as a Service companies, offering phishing attacks in exchange for payment. One Russian website, “Fake Game,” claims over 61,000 subscribers and 680,000 credentials stolen.

  2. They Work: Over 30% of phishing messages get opened, and 12% of targets click on the embedded attachments or links, according to the Verizon Data Breach Investigations Report. In short, these hackers have gotten really good at looking really legitimate.

  3. They’re simple to Execute: New phishing campaigns and sites can be built by sophisticated hackers in a matter of minutes. While we think there are far more legitimate ways to be earning money, these individuals have made a living out of duplicating their successful campaigns.
