What is Anubiscrypt ransomware?

Anubiscrypt ransomware – is a file locking malware that targets Android users

Anubiscrypt ransomwareAnubiscrypt ransomware is a file locking virus that can also steal banking information, intercept SMS service, install RAT and lock the screen

Anubiscrypt ransomware is a file locker that not only locks up personal data by appending .AnubisCrypt file extension on the device, but also incorporates screen-locking functionality. Additionally, it can steal the most sensitive information for the phone or tablet without users noticing. Thus, the malware is exceptionally devastating, as it can lock users out of their Android phones until the threat is terminated. The distribution method of the virus is relatively simple – hackers use Google Play service to insert fake financial, shopping, barcode-scanning or similar apps, that are mainly directed towards Turkish users. Anubiscrypt ransomware removal might be extremely complicated as most users will not be able to access their devices due to screen-locking feature. However, in this article, we will try to bypass this feature and terminate the threat permanently.

Anubiscrypt ransomware stems from Anubis banking trojan that was first spotted around a year ago. It works very similarly to a variety of info-stealers, such as TrickBot, LokiBot, Zeus virus or Gustuff. The initial version of the malware did not possess the screen-locking capability, while the newest version, which was discovered by ESET security researcher Lukas Stefanko,[1] does. Nevertheless, users can bypass the locked screen by entering Safe Mode.

Unlike most ransomware payloads, Anubiscrypt uses a sophisticated infection method – it populates malicious applications on the Google Play. Financial or shopping apps look just like any other applications, so regular users would never notice the difference.

Once one of such programs is installed on Android device, Anubiscrypt starts functioning as a downloader by utilizing REQUEST_PACKAGE_INSTALL function by contacting a Command & Control server controlled by hackers. Nevertheless, before the downloading procedure is executed, the app waits and does not perform any actions for a long time. This allows AnubisCrypt malware to bypass regular Google safety procedures.

Once the malicious payload is downloaded, a variety of information can be lured out of users, including those of PayPal, eBay, or banking app credentials For that, Anubiscrypt uses keylogging feature or takes screenshots of the login information (TrendMicro researchers confirmed that the malware targets 377 banking apps worldwide, including NatWest, Santander, Citibank, and others).[2]

Anubiscrypt virus utilizes a variety of capabilities, including:

  • Works as a RAT for hackers
  • Logs users' keystrokes
  • Steals the information from most banking apps
  • Intercepts SMS service to bypass banking app defenses
  • Locks personal files on external storage
  • Locks the screen

It is unknown which encryption algorithm is used to lock up personal files on the device, but all of them are marked with .AnubisCrypt extension, which prevents users from further use of data. After that, the malware locks up the screen, which might make most users panic. Nevertheless, to AnubisCrypt ransomware removal can be performed after the device is booted into Safe Mode – we explain how to do that in the last section of this article.

After you terminate Anubiscrypt ransomware, experts recommend scanning your Android device with ReimageIntego – it can fix damaged system files and remove virus damage. The only way to restore your data is by recovering them from a backup; hence, you should always enable the backup feature on Google Drive.

Anubiscrypt ranomware virusAnubiscrypt ransomware is one of the most devastating infections that Android users might encounter. However, the removal should be possible with powerful anti-malware software

Beware of suspicious apps – even on Google Play

It is not the first time Google removes malicious apps from the Play Store. For example, the industry giant removed 85 adware apps that infected over 9 million users. In another case, Kotlin-based malware was detected and downloaded up to 5,000 times. The app was called Swift Cleaner – another example of useless Android cleaning utilities that turned out to be malware. In fact, most security apps turned out to be ineffective, based on research done by AV-Comparatives researchers.[3]

Nevertheless, Google tries to tackle the problem by increasing the defenses used by its scanner, which already resulted in a 66% increase in rejected app volume in 2018.[4]

However, the risk of downloading malicious applications from third-party sites is by much higher. For that reason, it is highly advised staying away from unknown sites that host applications and rely on those that are present on the official stores, such as Google Play, Amazon, or similar.

Additionally, to protect your phone from malware, make sure you install reputable security software. Also, make sure you backup all your pictures, videos, and other data of Google Drive, DropBox, or similar cloud services.

Ways to remove and recover from Anubiscrypt ransomware infection

AnubisCrypt ransomware removal might be tricky, as the screen of the device gets locked after the infection. Nevertheless, entering the Safe Mode might temporarily stop this functionality and allow to control the device. To enter Safe Mode on your Android phone, perform these steps:

  • Hold the power button and wait for prompt;
  • Select Power off option;
  • Press Power button again, and wait till startup animation starts;
  • Then, press and gold Volume Up + Volume Down buttons;
  • The phone will ask if you want to access Safe Mode – tap Yes.

Once inside the Safe Mode, download and install a reputable security application that can detect malware. For example, Trend Micro detects it as ANDROIDOS_BANKBOT, while Sophos uses Andr/Banker-GUZ name. After you remove AnubisCrypt file virus, you can recover your data from backups. Otherwise, you might as well say goodbye to your pictures, videos, and other data. Nevertheless, security experts might one day come up with a decryptor, so do not lose hope, and keep backups of locked files.

If Anubiscrypt ransomware removal fails, the only option is to perform a factory reset. Simply use instructions based on your Android phone model. In most cases, the factory reset option is located under System option in the Settings menu.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
