Some Spyware Cases Recorded
Here are a few recent notable Syoware cases recorded:
1. Furball
Iranian citizens were targeted by another version of the FurBall Android spyware in mobile surveillance operations carried out by the Domestic Kitten hacking group, also known as APT-C-50 in 2022. The spyware was implemented in a large-scale surveillance operation that has been ongoing since at least 2016.
Researchers recently examined the latest version of the FurBall malware and found that it shared several characteristics with previous iterations and some new obfuscation techniques. The latest version of FurBall is spread through phony websites that mimic legitimate ones. Individuals fall into the trap of clicking on links in various forms of communication or through unethical SEO methods.
2. RatMilad – 2022
In 2022, researchers in the Middle East uncovered a new kind of Android spyware called RatMilad. This spyware targeted mobile devices and stole data from its victims. According to researchers, cyber espionage, extortion, and conversation eavesdropping were all possible uses for this software.
A phony social network account activation tool, “NumRent” was used to disseminate the spyware. After installation, the software asked for rights that could be harmful, and it leveraged those permissions to its advantage by sideloading the RatMilad malware.
Since the Google Play Store and third-party platforms do not host apps like NumRent or any other Trojans that contain RatMilador, Telegram became the primary means of distribution for the fraudulent app.
In order to make the mobile remote access trojan (RAT) app look more realistic, the RatMilad threat actors also established a dedicated website. Many social media networks, including Telegram, helped spread the word about this website.
3. PhoneSpy – 2021
A South Korean spyware program that infected Android devices was discovered by researchers in 2021. This malware, which went by the name of PhoneSpy, pretended to be a legitimate app in order to infiltrate the infected device, steal data, and exert remote control over it. The number of Android smartphones infected by this spyware is believed to exceed 1,000.
Yoga, movie streaming, and messaging apps were among the legitimate-looking apps found to contain PhoneSpy. Since these applications weren’t found in the Google Play Store, experts think the hackers used social engineering and phishing to spread the malware to other third-party platforms.
