Threat actors have been using Google Ads to promote fake websites that distribute malware to users looking to download the popular Notepad++ text editor. Malwarebytes spotted the campaign, which has been live for several months and targets users with malicious HTA scripts. When suspicious activity is detected, the campaign redirects users to a decoy site. To avoid downloading malware, only download software from official websites.
Security Report
Google Ads Exploited for Malicious Purposes: Malicious threat actors have been leveraging Google Ads to spread malware to unsuspecting users. This campaign focuses on distributing malware to individuals who are seeking to download the widely-used Notepad++ text editor.
Campaign Identified by Malwarebytes: The malvertising campaign came to the attention of cybersecurity experts at Malwarebytes, who detected its activities.
Extended Duration: This campaign has been operational for an extended period, spanning several months. Despite its longevity, it remained largely unnoticed, making it a notable cybersecurity threat.
Focus on Notepad++ Users: The campaign specifically targets individuals interested in downloading Notepad++. It takes advantage of users' trust in the software and their eagerness to obtain it.
Distribution of Malicious HTA Scripts: The attack mechanism employed in this campaign involves the distribution of malicious HTA (HTML Application) scripts to victims. These scripts can execute arbitrary code on a user's system and potentially download and install malware.
Deceptive Redirection: To avoid detection and suspicion, the campaign employs a redirection mechanism when it identifies suspicious behavior from users. If a user's actions indicate that they might be a security researcher, bot, or otherwise not the intended target, they are redirected to a decoy website to prevent them from analyzing the malicious payload.
Preventing Malware Downloads: The primary recommendation from cybersecurity experts is to download software only from official and trusted sources. In the case of Notepad++ or any other software, it's crucial to obtain it from the official website or reputable software repositories to reduce the risk of downloading malware.
This news underscores the continuous efforts of cybercriminals to exploit popular software and platforms to spread malware. It also highlights the importance of user vigilance and cybersecurity best practices to mitigate these threats.
Key Learnings
Sophisticated Google Search Malvertizing: This campaign targets users seeking to download Notepad++, a popular text editor, using advanced techniques to avoid detection.
Google Ads Abused for Malvertising: Cyber threat actors have increasingly used Google Ads to promote fake software websites distributing malware in their campaigns.
Long-Lasting Campaign: The Notepad++ malvertizing campaign identified by Malwarebytes had been running for several months without drawing attention.
Uncertain Final Payload: While the exact malware delivered is unknown, it's highly likely to be Cobalt Strike, a precursor to severe ransomware attacks.
Misleading URL Promotions: The campaign promotes URLs that are unrelated to Notepad++ but use misleading titles in Google Search result advertisements to deceive users.
Deceptive SEO Strategy: The campaign manipulates SEO by making the misleading titles more prominent than the actual URLs to lure victims into clicking on the ads.
Redirection and IP Filtering: Upon clicking the ads, users' IP addresses are checked to filter out crawlers, VPN users, and bots, while genuine users are redirected to a decoy site or the official Notepad++ site.
Second System Fingerprint Check: A JavaScript snippet performs a second system fingerprint check on users landing on the official Notepad++ site to ensure there are no anomalies indicating a sandbox environment.
Unique HTA Script for Suitable Targets: Victims who pass these checks receive an HTA script, assigned a unique ID for potential infection tracking. This payload is served only once per victim.
Cobalt Strike Connection: Analysis of the HTA script suggested a likely connection to Cobalt Strike, a well-known tool used in cyberattacks.
Precautions for Safe Downloads: To avoid downloading malware while seeking specific software tools, users should avoid clicking on promoted Google Search results and verify they are on the official domain.
Verify Software Authenticity: If unsure about the legitimacy of a project's website, users should check the "About" page, documentation, Wikipedia page, and official social media channels.
This highlights the importance of staying vigilant when downloading software and being cautious about the sources, especially when search engines like Google are manipulated for malicious purposes.
Diverse Perspectives
The Concerned User As a regular software user, this news is alarming. It's unsettling to think that while searching for legitimate software like Notepad++, one could unknowingly stumble upon malicious websites. It makes you question the safety of every download. The best advice here is to stick to official sources to avoid any unpleasant surprises.
The Cybersecurity Expert's View: Analytical From a cybersecurity perspective, this campaign is a prime example of how cybercriminals continue to exploit advertising platforms. Malwarebytes' identification of this campaign is commendable, but it also shows how such activities can go undetected for an extended period. To stay safe, always verify the source of the software you're downloading.
The Skeptical User's Take This isn't the first time we've heard about malware distribution through legitimate-looking websites. It's a reminder to be cautious while searching for software. Trusting only official sources is a start, but it also emphasizes the need for robust antivirus software to catch anything that might slip through.
The Cybercriminal's Defense I don't support cybercrime, but I have to say, this campaign's tactics are quite clever. It shows how even the most cautious users can be led to potentially harmful sites. Still, let's remember, the best defense against this is to download software only from the official website. So, in a way, these campaigns might make users more security-aware.
The Conspiracy Theorist's Stance You know, it's not just about downloading from official sites. Who's to say the official site itself isn't compromised? We're talking about big money and powerful interests. Who's watching the watchers? Stay vigilant out there.
The Technophobe's Worries This is exactly why I'm scared of downloading anything online. It's a minefield out there, and I don't want to risk infecting my computer. I'll stick to my old ways and avoid downloading software from the internet. It's safer.
The Apathetic User's Response Well, I guess it's a risk we take when we use the internet. I'll keep doing what I do, and if something goes wrong, I'll figure it out. It's not like I have anything super confidential on my computer anyway.
Security Perspective
Factual Analysis: Threat actors have cleverly used Google Ads to promote malicious websites, exploiting users seeking to download Notepad++. Malwarebytes identified this campaign, which has been active for months, and it employs malicious HTA scripts. When suspicious actions are detected, it redirects users to decoy sites. The key takeaway: sticking to official software sources is the safest approach.

Additionally, user education on recognizing deceptive practices and ensuring the source's authenticity could be a valuable approach. An integrated effort between users, security experts, and ad platforms is necessary.
Overall Understanding and Next Steps: This situation highlights the continuous need for vigilance in the digital realm. Users must exercise caution and refrain from downloading software from unofficial sources. Meanwhile, ad platforms should intensify their efforts in improving their screening processes. This collective approach will contribute to a safer online environment and better protection against threats like these.
