In November 2022, researchers at Google’s Project Zero warned about lively assaults on Samsung cell phones which chained collectively three safety vulnerabilities that Samsung patched in March 2021, and which might have allowed an app so as to add or learn any information on the gadget.
Google mentioned it believes the exploit chain for Samsung gadgets belonged to a “commercial surveillance vendor,” with out elaborating additional. The extremely technical writeup additionally didn’t identify the malicious app in query.
On Feb. 28, 2023, researchers on the Chinese safety agency DarkNavy revealed a weblog submit purporting to indicate proof {that a} main Chinese ecommerce firm’s app was utilizing this identical three-exploit chain to learn consumer information saved by different apps on the affected gadget, and to make its app practically not possible to take away.
The three Samsung exploits that DarkNavy says have been utilized by the malicious app. In November 2022, Google documented these three identical vulnerabilities getting used collectively to compromise Samsung gadgets.
DarkNavy likewise didn’t identify the app they mentioned was answerable for the assaults. In truth, the researchers took care to redact the identify of the app from a number of code screenshots revealed of their writeup. DarkNavy didn’t reply to requests for clarification.
“At present, a large number of end users have complained on multiple social platforms,” reads a translated model of the DarkNavy weblog submit. “The app has problems such as inexplicable installation, privacy leakage, and inability to uninstall.”
On March 3, 2023, a denizen of the now-defunct cybercrime group BreachForums posted a thread which famous {that a} distinctive element of the malicious app code highlighted by DarkNavy additionally was discovered within the ecommerce software whose identify was apparently redacted from the DarkNavy evaluation: Pinduoduo.
A Mar. 3, 2023 submit on BreachForums, evaluating the redacted code from the DarkNavy evaluation with the identical operate within the Pinduoduo app out there for obtain on the time.

That evaluation consists of hyperlinks to archived variations of Pinduoduo’s app launched earlier than March 5 (model 6.50 and decrease), which is when Davinci1010 says a brand new model of the app eliminated the malicious code.
Pinduoduo has not but responded to requests for remark. Pinduoduo mother or father firm PDD Holdings informed Reuters Google has not shared particulars about why it suspended the app.
The firm informed CNN that it strongly rejects “the speculation and accusation that Pinduoduo app is malicious just from a generic and non-conclusive response from Google,” and mentioned there have been “several apps that have been suspended from Google Play at the same time.”
