Eset security specialists are warning of a new malware sling for Android and iOS devices. Hackers use web address shortening services, so-called URL shorteners, and calendar entries to distribute malware.
According to researchers at security specialist Eset, aggressive advertising that downloads dangerous malware is currently up to mischief. “Android / FakeAdBlocker”, as the malware is called, usually hides its launcher icon and distributes unwanted scareware or pornographic advertisements. With Android, there is a risk of banking and SMS Trojans or malicious applications getting onto the devices. Some cases have happened in German-speaking countries. According to the Eset researchers, the Android / FakeAdBlocker alone was downloaded more than 150,000 times on Android devices from January 1 to July 1, 2021. Hundreds of other malicious apps were also installed.
Cyber criminals play with victims’ fear
“Our telemetry data shows that many users download Android apps outside of Google Play. Often they get to malicious apps that are distributed through aggressive advertising practices and generate income for the cybercriminals, ”explains Lukas Stefanko, the Eset researcher who analyzed Android / FakeAdBlocker. The current campaign is particularly dangerous for Android users, he adds.
“There are 18 events in the calendars that take place every day and each last ten minutes. Their names and descriptions suggest that the victim’s smartphone is infected with malware, that personal data has been published or that virus protection apps have expired, ”Stefanko reports on the scam. “The descriptions of the events each contain a link that leads the victim to a scareware advertising website. This website again claims that the device has been infected and offers the user the opportunity to download dubious cleaning applications from Google Play, ”said the specialist.
