Apologies For Interruption! POP-UP Scam (Mac)

What is Apologies For Interruption!?

"Apologies For Interruption!" is a fake error message similar to Phishing/Spyware Were Found On Your Mac, Critical System Error: x679Qs5m, and many others.

This pop-up is delivered by various rogue websites. Most users visit these sites inadvertently - they are redirected by intrusive advertisements or potentially unwanted programs (PUPs), which typically infiltrate systems without users’ permission. In addition to redirects, PUPs gather sensitive information and deliver intrusive advertisements.

   
ShutDownTime Adware

What is ShutDownTime?

ShutDownTime is a rogue application that supposedly allows users to set a time for the computer to shut down. Initially, ShutDownTime may seem legitimate, however, it is categorized as a potentially unwanted program (PUP) and adware.

There are three main reasons for these negative associations: 1) stealth installation without permission; 2) display of intrusive online advertisements, and; 3) monitoring of users' Internet browsing activity.

   
ProxyGate Adware

What is ProxyGate?

ProxyGate is an application that falsely claims to enhance the web browsing experience by providing access to a number of proxy servers. These fake promises often trick users into believing that ProxyGate is a legitimate application, however, it is categorized as adware and a potentially unwanted program (PUP).

There are three main reasons for these negative associations: 1) ProxyGate delivers various intrusive advertisements; 2) this application gathers various data types relating to Internet browsing activity, and; 3) ProxyGates often infiltrates systems without users' consent.

   
Sality Trojan Virus

What is Sality Trojan?

Sality is an old family of various malware. Although it originates from 2003, it is relevant today, since developers continually update these viruses and add new features.

They are proliferated in various ways, but mostly by cyber criminals employing spam email campaigns. They send thousands of deceptive emails encouraging users to open malicious attachments that stealthily infect the system.

   
KEYPASS Ransomware

What is KEYPASS?

KEYPASS is a high-risk ransomware-type virus that stealthily infiltrates the system and encrypts most stored data. We suspect this malware to be an updated variant of another ransomware infection called STOP. During encryption, KEYPASS appends filenames with the ".KEYPASS" extension (e.g., "sample.jpg" is renamed to "sample.jpg.KEYPASS").

Once encrypted, data immediately becomes unusable. Following successful encryption, KEYPASS generates a text file ("!!!KEYPASS_DECRYPTION_INFO!!!.txt") and places a copy in every existing folder.

   
Princess Ransomware

What is Princess?

Princess is a ransomware-type virus that encrypts most data stored on the infiltrated computer. During encryption, Princess appends the names of compromised files with random extensions.

This is quite uncommon, since most of ransomware appends a specific extension (for example, ".locked") or renames files using various patterns (e.g., "[5_random_characters]_[12_random_digits]_[unique_ID].[certain_extension]"). Note that updated variant of this ransomware is named "Princes Evolution".

Following successful encryption, Princess creates two files ("!_HOW_TO_RESTORE_[extension].TXT" and "!_HOW_TO_RESTORE_[extension].html") informing victims of the encryption (newer variants use =_HOW_TO_FIX_[victim's ID].txt and @_USE_TO_FIX_[unique_ID].txt names for the ransom demanding messages), and places them in each folder containing encrypted files.

Note that updated variants of this ransomware add ".*id*" extension to encrypted files. The ransom demanding message in the newer variants of this ransomware is presented in _USE_TO_REPAIR_[victim’s ID].html file.
