The risk actor often called Clear Tribe has continued to unleash malware-laced Android apps as a part of a social engineering marketing campaign to focus on people of curiosity.
“These APKs proceed the group’s pattern of embedding spy ware into curated video shopping purposes, with a brand new enlargement concentrating on cellular avid gamers, weapons fanatics, and TikTok followers,” SentinelOne safety researcher Alex Delamotte mentioned in a brand new report shared with The Hacker Information.
The marketing campaign, dubbed CapraTube, was first outlined by the cybersecurity firm in September 2023, with the hacking crew using weaponized Android apps impersonating professional apps like YouTube to ship a spy ware known as CapraRAT, a modified model of AndroRAT with capabilities to seize a variety of delicate information.

The group has a historical past of leaning into spear-phishing and watering gap assaults to ship a wide range of Home windows and Android spy ware.
“The exercise highlighted on this report exhibits the continuation of this method with updates to the social engineering pretexts in addition to efforts to maximise the spy ware’s compatibility with older variations of the Android working system whereas increasing the assault floor to incorporate fashionable variations of Android,” Delamotte defined.
The checklist of recent malicious APK recordsdata recognized by SentinelOne is as follows –
- Loopy Sport (com.maeps.crygms.tktols)
- Horny Movies (com.nobra.crygms.tktols)
