    A new Android bug, Strandhogg 2.0, lets malware pose as real apps and steal user data


    Protection researchers have found a main vulnerability in nearly just about every edition of Android, which lets malware imitate authentic apps to steal application passwords and other delicate info.

    The vulnerability, dubbed Strandhogg 2. (named immediately after the Norse expression for a hostile takeover) impacts all products operating Android 9. and earlier. It’s the “evil twin” to an previously bug of the exact same identify, according to Norwegian protection business Promon, which identified both equally vulnerabilities six months aside. Strandhogg 2. functions by tricking a sufferer into pondering they’re getting into their passwords on a respectable application though as a substitute interacting with a destructive overlay. Strandhogg 2. can also hijack other app permissions to siphon off delicate person knowledge, like contacts, shots, and track a victim’s real-time spot.

    The bug is stated to be more perilous than its predecessor because it is “nearly undetectable,” Tom Lysemose Hansen, founder and chief technologies officer at Promon, advised TechCrunch.

    The good news is that Promon mentioned it has no evidence that hackers have made use of the bug in lively hacking strategies. The caveat is that there are “no excellent ways” to detect an attack. Fearing the bug could continue to be abused by hackers, Promon delayed releasing information of the bug until Google could resolve the “critical”-rated vulnerability.

    A spokesperson for Google explained to TechCrunch that the organization also observed no proof of active exploitation. “We take pleasure in the operate of the scientists, and have unveiled a deal with for the issue they recognized.” The spokesperson claimed Google Enjoy Shield, an application screening assistance crafted-in to Android units, blocks apps that exploit the Strandhogg 2. vulnerability.

    Standhogg 2. will work by abusing Android’s multitasking process, which keeps tabs on each individual a short while ago opened app so that the consumer can immediately swap back and forth. A sufferer would have to download a destructive app — disguised as a normal application — that can exploit the Strandhogg 2. vulnerability. As soon as put in and when a victim opens a reputable application, the malicious application immediately hijacks the application and injects destructive written content in its spot, these types of as a fake login window.

    When a target enters their password on the phony overlay, their passwords are siphoned off to the hacker’s servers. The real app then seems as though the login was actual.

    Strandhogg 2. does not want any Android permissions to operate, but it can also hijack the permissions of other applications that have entry to a victim’s contacts, shots, and messages by triggering a permissions request.

    “If the authorization is granted, then the malware now has this harmful authorization,” reported Hansen.

    As soon as that permission is granted, the malicious application can upload information from a user’s telephone. The malware can upload complete text information discussions, claimed Hansen, permitting the hackers to defeat two-issue authentication protections.

    The risk to buyers is probable very low, but not zero. Promon claimed updating Android gadgets with the most up-to-date safety updates — out now — will fix the vulnerability. Consumers are recommended to update their Android products as shortly as attainable.
