What are Malvertisers?

Malvertisers are malicious actors who exploit online advertising to spread malware. They skillfully conceal their harmful intentions within ads that seem legitimate. When users unknowingly click on these deceptive ads, they expose themselves to malicious software. This could range from adware to more severe forms like ransomware or spyware, which can steal personal information or lock users out of their devices. As reported by The Hacker News, these malvertisers have become alarmingly sophisticated, using platforms like Google Ads to specifically target individuals searching for well-known software, greatly increasing the risk of harm.

DNS Filtering

To combat the growing malvertising and other malicious threats, Domain Name Service (DNS) filtering has become an essential tool. This method, which leverages the DNS, is crucial for blocking access to malicious, harmful, or inappropriate websites, thereby playing a vital role in safeguarding company data and strengthening security against various online threats. The need for robust DNS filtering solutions like Cisco Umbrella is especially important in the face of sophisticated cyber threats, such as those involving malvertising campaigns that manipulate Google Ads to mislead users or even traditional phishing attempts. These campaigns demonstrate the bad actors advanced evasion techniques, which make the implementation of effective DNS filtering more crucial than ever.

Cisco Umbrella

At Network Thinking Solutions, we understand the importance of robust cybersecurity. This is why Cisco Umbrella is a fundamental part of our security measures. It serves as more than just a tool, it’s a proactive defense against the constantly evolving cyber threats. With its DNS filtering capabilities, Cisco Umbrella doesn’t just block known malicious sites but also adeptly identifies and restricts access to emerging threats and content deemed inappropriate for business environments.

Responding to Advanced Threats

Leveraging Cisco’s Talos team for its core intelligence, Cisco Umbrella stands as a comprehensive threat detection tool. At Network Thinking Solutions, we’ve taken this a step further by integrating URLhaus malware data into Cisco Umbrella through a SOAR workflow. With URLhaus’s extensive database of malicious URLs, our use of Cisco Umbrella’s blocking features becomes even more effective. Integrating URLhaus’s extensive database of malicious URLs ensures Cisco Umbrella’s blocking features stay ahead of new threats, providing real-time protection against the constantly evolving malvertising threat environment. This is a first step to a proactive approach that is especially crucial for dealing with sophisticated campaigns.
