Watch Out for Google Searches – “Malvertising” Is on the Rise!

Understanding the Growing Threat of Malvertising

In today’s digital landscape, malware comes in various forms, with malvertising being one of the most prevalent. These malicious ads infiltrate numerous platforms, including social media sites, commercially popular websites, and even appear in Google searches.

The Rising Danger of Malvertising

Two significant factors are escalating the threat of malvertising:

1. Advanced AI Techniques: Cybercriminals are leveraging artificial intelligence to create highly convincing malicious ads, making them harder to detect.
2. Increasing Incidence: According to Malwarebytes, malvertising incidents surged by 42% month over month in Autumn 2023.

Staying informed about such online threats is crucial. Knowledge empowers you to protect your business from sophisticated cybercriminals. Below, we delve into what malvertising entails and provide essential tips to identify and avoid it.

What Is “Malvertising?”

Malvertising involves the use of online advertisements to conduct malicious activities. A classic example occurred during the launch of the PlayStation 5. The high demand and limited availability created an ideal opportunity for hackers. Numerous deceptive ads appeared in Google searches, mimicking official websites. These counterfeit sites were designed to steal user credentials and credit card information.

While Google strives to regulate its ads, malicious ads can often remain active for hours or even days before being identified and removed. These ads blend seamlessly with legitimate sponsored search ads, making them difficult to distinguish.

However, Google isn’t the only platform vulnerable to malvertising. Compromised well-known websites and social media feeds are also common places where these malicious ads appear.

Tips for Protecting Your Business from Malicious Online Ads

Safeguarding your business from malvertising is essential. Here are some effective strategies:

Review URLs Carefully

Malvertising often relies on slightly misspelled URLs to trick users into visiting copycat websites. Always scrutinize links for any inconsistencies or unusual characters before clicking.

Visit Websites Directly

Avoid clicking on ads altogether. Instead, navigate to the official website directly. For instance, if a legitimate company is having a big sale, this information will be available on their official site. This practice helps prevent falling victim to phishing scams and malvertising.

Use a DNS Filter

A DNS filter can safeguard your business by redirecting your browser to a warning page if a dangerous site is detected. These filters identify potential threats and block access, ensuring your employees remain safe even if they accidentally click on a malicious link.

Do Not Log in After Clicking an Ad

Malvertising can redirect you to imitation login pages that look identical to the real ones. These fraudulent sites aim to steal login credentials for services like banking, streaming, and more. If you accidentally click an ad, refrain from entering your login details. Instead, access the legitimate website through a different browser tab.

Don’t Call Ad Phone Numbers

Some malicious ads include phone numbers, tricking users into calling fake representatives who then extract personal information. This tactic often targets vulnerable groups, such as seniors. Always avoid calling numbers provided in online ads. If contacted, do not disclose any personal data and hang up immediately.

Don’t Download from Ads

Ads promising free software downloads, such as “Get a free copy of MS Word” or “Free PC Cleaner,” are common malvertising scams. These links often install malware on your system, allowing hackers to cause further damage. Never download anything directly from an online ad. If you need software, always download it from the official website.

Warn Others When You See Malvertising

If you encounter a suspicious ad, inform your colleagues, friends, and family. Raising awareness helps create a cyber-aware community, enhancing overall online security and alerting others to new scams.
