MyTelkomsel Hacked Sends Message “NO SYSTEM IS SAFE!”
The MyTelkomsel app suddenly sent a strange notification with a provocative message. This incident sparked hacking speculation.

Several users of the MyTelkomsel app reported receiving a strange push notification in the early morning containing the message “NO SYSTEM IS SAFE!” The message was accompanied by an image of someone wearing a scary mask. Until now, Telkomsel has not issued an official statement or explanation regarding the incident.
Brief chronology
In the early morning, several MyTelkomsel users (iOS) received push notifications from the official app with the text “NO SYSTEM IS SAFE!” accompanied by an image of a person in a creepy costume/mask. Android users reportedly did not experience the same issue.
These reports appeared on social media, but there has been no further confirmation from Telkomsel about the source or cause of the notification.
What is known (and what is unclear)
Known: The notification was indeed received by some users and contained a provocative message along with a frightening image.
Unclear: Whether this originated from Telkomsel’s official servers (e.g., due to infiltration), from a connected third-party service, or an internal technical error. Telkomsel has not provided a public statement at the time this report was written.
This Incident Not Only Affected Telkomsel but Also Other Popular Applications in Various Countries
Reports of similar attacks have emerged in Turkey, where several popular applications were also impacted.
Case in Turkey: Coordinated Attack
According to Turkish media reports, on Tuesday night, several major applications in the country were infiltrated by hackers:
- Nays (banking app)
- Domino’s Pizza
- LCW (fashion retailer)
- Fenerbahce (football club app)
Users of these applications received push notifications with the same message, indicating a coordinated cyber operation. The message is suspected to reference the 2014 German film “Who Am I: No System Is Safe”, complete with its tagline and iconic masked visuals.
Not a Specific Target on Telkomsel?
Based on the incident patterns, the attack does not appear to be specifically aimed at Telkomsel. Indications show that hackers performed brute force attacks on various applications that happened to use vulnerable code in their push notification systems. This is further supported by the fact that similar incidents occurred simultaneously across multiple countries.
No Party Has Claimed Responsibility Yet
So far, no group or individual has claimed responsibility for the attack. Both Telkomsel and the affected companies in Turkey have yet to issue official statements. Security researchers warn that other applications may also be at risk as investigations continue.
Notifications like this can cause panic, confusion, and doubt about the app’s security. If there is indeed an infiltration, user data or related services could be at risk, but at this point, there is no public evidence confirming any data theft.
