ProSpy

ProSpy is an Android spyware family, detected by ESET as Android/Spy.ProSpy, that has been active since at least 2024 and was discovered in June 2025. It was distributed outside official app stores via fake websites and phishing pages, primarily targeting users in the United Arab Emirates. ProSpy impersonated a nonexistent Signal Encryption Plugin and a fake ToTok Pro application; reporting also states it masqueraded as other communications apps including WhatsApp, Zoom, and Botim in related campaigns. Known distribution domains mentioned in the reporting include signal.ct[.]ws, encryption-plug-in-signal.com-ae[.]net, and totok-pro[.]io.

Once installed, ProSpy requests access to contacts, SMS messages, and files stored on the device, then exfiltrates sensitive data including device information, public IP address, SMS messages, contact lists, installed applications, and files such as documents, archives, images, audio, and video. Reported local staging filenames include contacts_list.json, device_info.json, and sms_list.json. In broader reporting on associated espionage activity, ProSpy was described as capable of stealing chats, files, media, SMS messages, contacts, and app backups, and in some accounts as providing full device control.

The malware uses persistence mechanisms including foreground services, AlarmManager restarts, and BOOT_COMPLETED receivers. The Signal-themed variant could change its icon and label to Play Services using Android activity-alias functionality, launch the legitimate Signal app, or redirect users to signal.org if Signal was not installed. The fake ToTok Pro variant redirected users to the official ToTok download page and later launched the real ToTok app to reduce suspicion.

Multiple reports link ProSpy to espionage targeting journalists, activists, opposition figures, and some government-linked individuals across the Middle East and North Africa, with confirmed or likely targeting in the UAE and reporting also naming Egypt, Lebanon, and Bahrain. Lookout attributed malware used in this broader campaign to the South Asian threat group BITTER, also known as T-APT-17 and APT-Q-37, citing code similarities between ProSpy and the earlier Dracarys malware, though ESET stated attribution for the ProSpy campaign itself remained unknown. Researchers assessed the activity as surveillance-oriented and possibly hack-for-hire. CISA later highlighted ProSpy among spyware campaigns abusing trust in messaging applications to target high-value individuals.

This joint research, and an October 2025 report from ESET, reveals that Android users are tricked into downloading any of these malware: ProSpy or ToSpy. Both are spyware... Researchers explain that ProSpy is a feature-rich spyware developed in Kotlin, and out of the 11 ProSpy samples obtained, the earliest was from August 2024.

MITRE ATT&CK

Techniques & procedures

17 distinct techniques documented for this family, organized by ATT&CK tactic.

Initial Access

4 techniques
T1189Drive-by CompromiseEvidence2

The spyware is installed through fake websites and app stores... The apps containing the spyware can only be installed manually via third-party websites, according to ESET researcher Lukáš Štefanko.

T1566PhishingEvidence4

Distribution methods include phishing domains designed to mimic legitimate app marketplaces, including a fake Samsung Galaxy Store.

T1566.002Spearphishing LinkEvidence3

The operator of the spyware campaign distributed the malicious APK files through web pages that impersonated the official Signal website ... and the Samsung Galaxy Store.

T1566.003Spearphishing via ServiceEvidence1

Researchers found that some targets were sent messages on LinkedIn or through iMessage, and some pretended to be from Apple Support.

Execution

3 techniques
T1053Scheduled Task/JobEvidence3

After installation, ProSpy and ToSpy use Android persistence mechanisms, such as AlarmManager and boot receivers, to ensure continued operation even after device reboots.

T1204User ExecutionEvidence2
TacticExecution

Neither app appears in official app stores; victims have to manually install APK files from cloned websites or third-party pages designed to look like legitimate services.

T1204.002Malicious FileEvidence3
TacticExecution

Neither app containing the spyware was available in official app stores; both required manual installation from third-party websites posing as legitimate services.

Persistence

3 techniques
T1053Scheduled Task/JobEvidence3

After installation, ProSpy and ToSpy use Android persistence mechanisms, such as AlarmManager and boot receivers, to ensure continued operation even after device reboots.

T1547Boot or Logon Autostart ExecutionEvidence2

After installation, ProSpy and ToSpy use Android persistence mechanisms, such as AlarmManager and boot receivers, to ensure continued operation even after device reboots.

T1547.001Registry Run Keys / Startup FolderEvidence1

To achieve persistence, both the spyware families run a foreground service that displays a persistent notification, use Android's AlarmManager to repeatedly restart the foreground service if it gets terminated, and automatically launch the necessary background services upon a device reboot.

T1053Scheduled Task/JobEvidence3

After installation, ProSpy and ToSpy use Android persistence mechanisms, such as AlarmManager and boot receivers, to ensure continued operation even after device reboots.

T1547Boot or Logon Autostart ExecutionEvidence2

After installation, ProSpy and ToSpy use Android persistence mechanisms, such as AlarmManager and boot receivers, to ensure continued operation even after device reboots.

T1547.001Registry Run Keys / Startup FolderEvidence1

To achieve persistence, both the spyware families run a foreground service that displays a persistent notification, use Android's AlarmManager to repeatedly restart the foreground service if it gets terminated, and automatically launch the necessary background services upon a device reboot.

Stealth

1 technique
T1036MasqueradingEvidence8
TacticStealth

Cybersecurity researchers have discovered two Android spyware campaigns dubbed ProSpy and ToSpy that impersonate apps like Signal and ToTok to target users in the United Arab Emirates (U.A.E.).

Discovery

TacticDiscovery

It's also capable of exfiltrating device information.

T1518Software DiscoveryEvidence1
TacticDiscovery

If granted, the spyware collects device details, SMS messages, contact lists, installed app lists, and files, including chat backups.

Collection

1 technique
T1005Data from Local SystemEvidence5

The spyware is installed through fake websites and app stores, and it allows sensitive data files, contacts, chat backups and media to be stolen.

All collected data is encrypted with a hardcoded AES key, then sent to command and control servers.

Exfiltration

1 technique
T1041Exfiltration Over C2 ChannelEvidence3

Once installed, they continually exfiltrate sensitive data.

Other

1 technique
T1656ImpersonationEvidence1

The operation features a combination of targeted spearphishing delivered through fake social media accounts and messaging applications leveraging persistent social engineering efforts...
