“These APKs proceed the group’s trend of embedding spyware into curated video browsing purposes, with a new growth targeting cellular gamers, weapons lovers, and TikTok followers,” SentinelOne security researcher Alex Delamotte explained in a new report shared with The Hacker Information.

The marketing campaign, dubbed CapraTube, was initial outlined by the cybersecurity enterprise in September 2023, with the hacking crew utilizing weaponized Android apps impersonating genuine apps like YouTube to provide a spy ware called CapraRAT, a modified edition of AndroRAT with capabilities to capture a extensive array of delicate info.

Clear Tribe, suspected to be of Pakistan origin, has leveraged CapraRAT for in excess of two several years in attacks concentrating on the Indian govt and armed service personnel. The group has a heritage of leaning into spear-phishing and watering hole attacks to deliver a wide range of Windows and Android spy ware.

“The exercise highlighted in this report demonstrates the continuation of this technique with updates to the social engineering pretexts as properly as efforts to improve the spyware’s compatibility with older versions of the Android running method even though expanding the attack floor to involve contemporary versions of Android,” Delamotte stated.

“Apparently, FjordPhantom and Snowblind concentrate on applications from Southeast Asia and leverage potent new attack techniques. That looks to suggest that malware authors in that area have become incredibly complex.”

“The updates to the CapraRAT code in between the September 2023 marketing campaign and the current marketing campaign are minimal, but advise the developers are focused on creating the software much more trusted and secure,” Delamotte reported.

“The final decision to transfer to more recent variations of the Android OS are rational, and most likely align with the group’s sustained concentrating on of folks in the Indian authorities or armed forces place, who are unlikely to use products running more mature variations of Android, these kinds of as Lollipop which was unveiled 8 several years in the past.”
