Stinger Ransomware

Posted: March 20, 2018

Stinger Ransomware Description

The Stinger Ransomware is a file-locker Trojan that blocks your opening of different media kinds, including documents and pictures, with the intention of collecting ransoms for its unlocking service. While malware experts always suggest keeping backups that reduce any harm from attacks by threats of this category, users also may contact an experienced cyber-security specialist for decryption help that could restore their files. Most anti-malware products are eliminating the Stinger Ransomware as a threat by default, without any further issues.

Feeling the Sting of Bad ASCII Art

A new type of file-locking threat is observable in the wild, with no evidence of a relationship to growing families like the free Hidden Tear or the RaaS-focused Globe Ransomware. Whether the Stinger Ransomware's administrators are running it with a portion of the profits going to its programmer or the Trojan is an entirely independent program, this threat is deploying with full-fledged features oriented towards blocking data for money. Malware experts can't identify its currently in-use infection techniques, although the Stinger Ransomware only runs on Windows software-compatible systems.

The Stinger Ransomware's executable is, like those of most, file-locking threats, under a megabyte, and uses an initial Mutex registration for preventing multiple installations and running instances. Its payload uses an encryption attack that malware experts estimate as basing itself off of AES-128, AES-192, or AES-256, which converts every file it targets into a non-opening, enciphered equivalent. The formats having confirmation for this attack include DOC and PDF documents, MP3 audio and JPG and PNG images. No evidence is available for the Stinger Ransomware's harming the operating system or other files that are integral to your PC's basic operations, but it may delete any default backups or restore points.

Other, traditional features that malware experts are citing as present within the Stinger Ransomware's payload are as follows:

  • A simple, extension-appending function adds the superficial format of '.Stinger' to all the filenames of any media that the Stinger Ransomware is blocking.
  • The Stinger Ransomware also places a TXT file inside of any locations containing the encrypted data. The message inside displays a simple ASCII artwork of a skull and crossbones, a ransom demand for 100 USD, and the threat actor's e-mail address for acquiring the other payment details. the Stinger Ransomware provides translations of its text in several languages, including English, German and French.

The Ointment for a Trojan's Touch on Your Files

The Stinger Ransomware campaign is using unknown infection strategies. Attacks deploying threats in its category can abuse corrupted e-mail content, document macros, brute-force hacks against weak passwords, RDP vulnerabilities, and exploit kits that can load via your Web browser. Installing updates as appropriate, scanning downloads before opening them, and avoiding piracy-related sites and file-sharing networks are meaningful ways of preventing these attacks from occurring.

Encryption is not always reversible, and malware experts recommend against assuming that any media that the Stinger Ransomware locks are recoverable via a free decryption program necessarily. Users should save regular backups to devices that this Trojan can't compromise, such as a cloud or USB storage, instead of allowing the Trojan to extort money after damaging the only copies of their work. However, well over half of most brands of anti-malware products are deleting the Stinger Ransomware before it can encrypt any files.

The Stinger Ransomware seems most likely of being a Trojan with intentions of harming casual PC owners, rather than companies. Whether you're a 'small fry' or a multinational corporation, there's an extortionist, encryption-abusing Trojan for you.
