Greetings, dear reader! Isn’t it fascinating to observe how our lives have become seamlessly integrated with the digital world? We share, learn, connect, and even unwind on the vast expanse that is the Internet. Yet, this captivating digital frontier is not without its perils. As we delve deeper into the wonders of the World Wide Web, we must also brace ourselves against the threats that lurk within it. One such menace that has been making headlines is “malvertising”—a devious scheme that combines the ubiquity of online advertising with the destructive potential of malware. The threat of malvertising presents a new fork in the road of malicious use of technology for personal benefit.
As we navigate through the intricate maze of this topic, we’ll be looking at how the threat of malvertising works, its impact, and a recent case that has swept across the cybersecurity landscape. Our hope is that by sharing this information, we can empower each other to be more aware and safer as we traverse the digital landscape.
The Menace of Malvertising
First, let’s break down what “malvertising” means. It’s a portmanteau of the words “malicious” and “advertising.” Essentially, it’s the practice of spreading malware through online advertisements. Imagine a simple ad on a website—only this one is injected with a lethal code. Click on it, and you might either be directed to a fraudulent website or, worse, become the unwilling recipient of a nasty malicious payload.
And here’s where it gets scary—the servers displaying these ads might not even know they’ve become unwilling accomplices in these digital crimes. Remember the domains of renowned establishments like The New York Times, BBC, AOL, and MSN? They’ve all fallen victim to malvertising campaigns, with VeryMal being a notable example. The threat of Malvertising still remains at large and it’s a new concern generated by the advancement of our technology.
The Costly Impact and Threat of Malvertising
In 2017 alone, malvertising led to a whopping loss of $1.13 billion for ad networks. And yes, malvertising is very much alive and kicking today, as evidenced by the recent spread of the GreenFlash Sundown exploit kit.
The GreenFlash Sundown Exploit and Its Far Reach
Malwarebytes researcher Jérôme Segura recently highlighted an exploit kit known as GreenFlash Sundown. Once considered elusive and primarily confined to Asia, it is now expanding its reach. Who is a recent victim? The servers of onlinevideoconverter[.]com—a popular service transforming YouTube videos into audio files, boasting over 200 million users per month! The threat of malvertising and its vast reach and use in the internet platforms (especially for sites that let you download online content/service) present a new battle frontier for cyber security.
The Exploit Pathway
If the exploit succeeds, it deploys the Seon ransomware (find out what’s Seon ransomware), first observed back in 2018. This nasty piece of work encrypts a system’s files, demands a Bitcoin-based ransom, and even erases Shadow Volume copies on disk to hinder data recovery.
And it doesn’t stop there! Along with the ransomware, the payload also delivers a cryptocurrency miner and Pony, a notorious data thief.
From Asia to the West: The Expanding Threat
Initial investigations into the exploit kit confined its spread within South Korea. However, recent updates reveal a more global threat, with the campaign now reaching into the US and Europe.
Upon learning of the problem, the team at Online Video Converter responded swiftly. They made themselves clear by saying: “We have only just been made known of the issue, and have currently disabled our ad server while looking further into the issue.”
This tale serves as a stark reminder of the digital dangers lurking behind seemingly innocuous corners of the web. So, what can we do to protect ourselves?
Here’s a start: Keep your software updated, use reliable antivirus programs, enable ad-blockers, and above all, stay informed. The threats may be evolving, but so must our defenses. Remember, in the realm of cybersecurity, knowledge is power!
