Online criminals are abusing Google search results to trick users into downloading fake app installers.
At the center of the crime is SEO poisoning, in which attackers manipulate search algorithms using SEO plugins, lookalike domains, and sometimes paid ads so that malicious sites appear among the top results for popular apps such as Signal, WhatsApp, Deepl, Chrome, Telegram, Line, VPN services, and WPS Office. These websites closely imitate genuine vendor pages, right down to branding and layout, so users believe they are downloading official installers.
Instead, these installers are "trojanized". This means they contain a real application so it appears normal post-installation, but they also deploy malware with some with advanced remote?access and surveillance tools. These malware families can log keystrokes, capture clipboard data and screenshots, monitor or hijack messaging apps, exfiltrate personal and financial information and, in some documented chains, even interfere with, or disable, antivirus products.
These malware campaigns have also targeted productivity tools favored by employers and employees. Ransomware and other malware have been distributed via fake installers for AI tools such as ChatGPT and InVideo or spoofed sites impersonating PayPal, Microsoft, Netflix, Apple, and major banks.
In many cases, attackers also purchase sponsored Google ads so their poisoned links appear above organic results, increasing the chance that cautious users who deliberately choose "top" results are still funneled into malicious downloads.

Commentary
Criminals exploit a false belief that "top results" from Google equate to safe or even vetted results. For employees searching popular productivity apps like messaging tools, browsers, or VPNs, fake websites can appear near the top of the results that appear identical to real providers.
From a loss prevention standpoint, this is not just an "IT issue"; it is a direct pathway to fraud, data breaches, regulatory violations, and reputational damage that starts with a single careless download.
Prevention starts with training employees to stop using search results as a shortcut to download software. Instead of typing an app name into a search engine and clicking whatever appears at the top, go directly to known official sources of the app.
Employers should provide and employees should use an approved software portal, store, or list.
Another prevention step is to slow down and look closely at any website before downloading anything. Many malicious sites rely on tiny visual tricks, such as a domain name that is off by one letter, an extra word, or an unusual ending that is not normally used by that company.
A legitimate brand page that suddenly looks slightly "off," contains poor spelling, aggressive pop?ups, or pushes unexpected toolbars or "system cleaners" is a warning sign. If anything feels wrong or rushed, employees should stop immediately and ask for help rather than guessing.
Keep devices and security tools up to date. When operating systems, browsers, and security software are updated regularly, many known threats are blocked before they can do damage. Employees should never disable or ignore antivirus, browser warnings, or security prompts just to "get something installed faster." If a download suddenly asks for unusual permissions, administrator rights, or insists on disabling protections, that should be treated as a red flag and reported.
Password and account hygiene also matter when dealing with this type of threat. If a fake installer manages to capture passwords, it can only do limited damage if employees use strong, unique passwords for each account and, where available, turn on multi?factor authentication.
Using a safe, proven, and reputable password manager makes it easier to avoid reusing passwords and to change them quickly if there is a concern that something may have been compromised.
The final takeaway is that employees should be encouraged to speak up promptly if they think they may have installed something suspicious. Early reporting allows security staff to contain the issue before it becomes a major loss.
