The Iranian risk actor referred to as Domestic Kitten has been attributed to a brand new cellular marketing campaign that masquerades as a translation app to distribute an up to date variant of an Android malware referred to as FurBall.
“Since June 2021, it has been distributed as a translation app by way of a copycat of an Iranian web site that gives translated articles, journals, and books,” ESET researcher Lukas Stefanko stated in a report shared with The Hacker News.
The updates, whereas retaining the identical surveillance performance as earlier variations, are designed to evade detection by safety options, the Slovak cybersecurity agency added.
Domestic Kitten, additionally known as APT-C-50, is an Iranian risk exercise cluster that has been beforehand recognized as focusing on people of curiosity with the purpose of harvesting delicate data from compromised cellular gadgets. It’s been recognized to be energetic since at the very least 2016.
A tactical evaluation carried out by Trend Micro in 2019 revealed Domestic Kitten’s potential connections to a different group known as Bouncing Golf, a cyber espionage marketing campaign focusing on Middle Eastern international locations.
APT-C-50 has primarily singled out “Iranian residents that might pose a risk to the steadiness of the Iranian regime, together with inside dissidents, opposition forces, ISIS advocates, the Kurdish minority in Iran, and extra,” based on Check Point.
Campaigns undertaken by the group have historically relied on luring potential victims into putting in a rogue utility by way of completely different assault vectors, together with Iranian weblog websites, Telegram channels, and SMS messages.
Irrespective of the tactic employed, the apps act as a conduit to ship a bit of malware codenamed by the Israeli cybersecurity firm as FurBall, a custom-made model of KidLogger which comes with capabilities to collect and exfiltrate private information from the gadgets.
The newest iteration of the marketing campaign uncovered by ESET entails the app working underneath the guise of a translation service. Previous covers used to hide malicious conduct span completely different classes reminiscent of safety, information, video games, and wallpaper apps.
The app (“sarayemaghale.apk“) is delivered by way of a faux web site mimicking downloadmaghaleh[.]com, a respectable website that gives articles and books translated from English to Persian.
What’s notable in regards to the newest model is that whereas the core spy ware capabilities are retained, the artifact requests just one permission to entry contacts, limiting it from accessing SMS messages, system location, name logs, and clipboard information.
“The purpose may very well be its intention to remain underneath the radar; alternatively, we additionally assume it’d sign it’s simply the previous part of a spear-phishing assault carried out by way of textual content messages,” Stefanko identified.
Despite this handicap, the FurBall malware, in its current kind, can retrieve instructions from a distant server that enables it to collect contacts, recordsdata from exterior storage, an inventory of put in apps, primary system metadata, and synced consumer accounts.
The discount in energetic app performance however, the pattern additional stands out for implementing an elementary code obfuscation scheme that is seen as an try and get previous safety limitations.
“The Domestic Kitten marketing campaign continues to be energetic, utilizing copycat web sites to focus on Iranian residents,” Stefanko stated. “The operator’s purpose has modified barely from distributing full-featured Android spy ware to a lighter variant.”
