For Fuck’s Sake: Yet Another Android Backdoor That’s Practically Fucking Immortal
Just when you thought the Android ecosystem couldn’t get more diseased, some security researchers have gone and discovered “Keenadu” – a backdoor so deeply embedded in cheap phone firmware that removing it requires skills I wouldn’t waste on your sorry ass. This little gem is brought to you by the “Lemon Group,” who used to call themselves “Guerrilla” until they realized that naming your cybercrime outfit after a fucking zoo animal wasn’t subtle enough. These charming bastards claim they’ve infected 8.9 million devices, which is 8.9 million people who deserve exactly what they got for buying a phone that costs less than a decent bottle of whisky.
Here’s the truly hilarious part: this shit is pre-installed in the firmware by those paragons of quality, the no-name Chinese manufacturers. When Grandpa turns on his new “HappyFuntimePhone Pro Max” for the first time, system apps immediately install Keenadu with full root access. A factory reset does precisely fuck-all because the malware lives in the system partition like a tapeworm in your intestine. The only way to truly remove it involves a degree in firmware engineering that you don’t have and a level of give-a-shit that I certainly don’t have.
But wait, there’s more! Some developers – and I use that term as loosely as a wizard’s sleeve – decided to integrate a “free” advertising SDK from a riskware developer called “logan.hkt.” Because nothing says “I care about my users’ security” like adding code from a developer whose previous hits include “Aggressive Ad Spam Deluxe” and “Data Harvester Ultra.” This SDK infected two apps that sailed through Google’s famously rigorous “did you fill out the form correctly” security screening: “Multi SMS Sender” (100,000+ downloads) and “Phone Finder – GPS Location Tracker” (200,000+ downloads). That’s 300,000 naive twats who actually believed the Play Store was safe.
Keenadu’s capabilities are a malware enthusiast’s wet dream: remote plugin loading, data theft, browser URL injection, SMS fraud, relentless ad spam, and installing even more malicious shit. It’s got obfuscation techniques that would make a Russian hacker blush – dynamic API resolution, DEX decryption, emulator detection. The command and control server sits at keenai[.]com on Alibaba Cloud, because if you’re running a global crime operation, you might as well host it on infrastructure with the takedown responsiveness of a sloth on ketamine.
The plugins are where the real fun begins: “Slik” injects URLs into your browser, “Mms” intercepts texts for premium rate fraud, “Cns” hijacks notifications, “Ads” shits ads everywhere, “App” installs more malware, and “Top” overlays UI elements to steal credentials. It’s a full-service digital fuck-you toolkit.
So here’s your takeaway, which you’ll ignore because you’re a mouth-breathing imbecile: Stop buying cheap Android garbage, stop trusting random SDKs, and understand that Google’s app vetting is about as thorough as a TSA agent with a hangover. Your phone is probably infected already, not that you’d notice through the layer of TikTok and Candy Crush.
Anecdote: Some peon from HR staggered into my office yesterday with one of these infected burners, complaining it was “acting funny.” I glanced at the screen for exactly 3.7 seconds, saw seventeen different malware families having an orgy in the process list, and told him the only certified fix was a “thermal recalibration” – which involves placing the phone in a microwave for 90 seconds. The moron actually did it. The device caught fire, destroyed the microwave, and set off the sprinklers. Now he’s demanding IT replace both the phone AND the microwave. I told him to submit his request to the Department of Pie in the Sky, attention: Mr. Go Fuck Yourself. I’m still cleaning up the water damage, but it was worth it.
