“Dirty stream” attack: Discovering and mitigating a common vulnerability pattern in Android apps
Microsoft discovered a vulnerability pattern in multiple popular Android applications that could enable a malicious application to overwrite files in the vulnerable application’s internal data storage directory, which could lead to arbitrary code execution and token theft, among other impacts. We have shared our findings with Google’s Android Application Security Research team, as well as the developers of apps found vulnerable to this issue. We anticipate that the vulnerability pattern could be found in other applications. We’re sharing this research more broadly so developers and publishers can check their apps for similar issues, fix as appropriate, and prevent them from being introduced into new apps or releases.

In late August 2023, we observed an intrusion that started with a phishing campaign using PrometheusTDS to distribute IcedID. IcedID dropped and executed a Cobalt Strike beacon, which was then used through-out the intrusion. The threat actor leveraged a bespoke PowerShell tool known as AWScollector to facilitate a range of malicious activities including discovery, lateral movement, data exfiltration, and ransomware deployment. Group Policy was used to distribute Cobalt Strike beacons at login to a specific privileged user group. The threat actor utilized a suite of tools to support their activities, deploying Rclone, Netscan, Nbtscan, AnyDesk, Seatbelt, Sharefinder, and AdFind. * This case had a TTR (time to ransomware) of 29 days.
