Ariomex, Iran-based crypto exchange, suffers data leak

Resecurity says Iran’s Ariomex crypto exchange suffered a data leak exposing user and transaction data from 2022 to 2025.

Resecurity (USA) reports that Ariomex’s database, one of Iran’s cryptocurrency exchange platforms, suffered a data leak. The report published by the cybersecurity company presents the findings of a structured analysis of the leaked database, which contains information about end users, their transactions, and the context surrounding their operations, covering the period from 2022 to 2025.

For example, in one of the intercepted communications, Resecurity identified an individual named Seyyed Younes Shokori Bilankouhi requesting to deposit 3 million USD “with the help of the Iranian embassy.” In another case, an individual named Ramin Lak wanted to exchange 5 million USD. Notably, some users used Ariomex as a “bank”—purchasing crypto and storing it there for future use, similar to a traditional bank account. For example, user Eyraj Jaafari bought digital assets worth 100,000 USD multiple times but preferred to “cash out later.”

The experts highlighted that some of the observed records with substantial balances lacked KYC, or the provided information was modified. Resecurity identified multiple suspicious transactions involving large amounts exceeding millions of USD in value.

The data highlights the footprint of Iranian cryptocurrency holders in other geographies, including the US, the UK, Germany, France, the Netherlands, Romania, Russia, Sweden, Turkey, and many others. This intelligence could help block Iranian moneylenders and criminals from entering foreign markets.

A total of 11,826 records were identified, of which around 7,710 originate from Iran, based on IP address data and associated network intelligence. Ariomex data reveals substantial details about the user profiles, their identities, e-mails, IP addresses, and associated cryptocurrency operations.

Example:

  • Asking to buy (exchange) $19 Million USD
  • Email: [email protected]
  • FirstName: Zahra
  • Surname: Khazaei
  • IP: 5.126.48.39
  • OS: Android 8.0.0
  • Browser: Chrome 106.0.0.0
  • Country: Iran

Resecurity identified a stolen Ariomex database circulating on the Dark Web. The root cause of the breach was likely a compromised customer support (helpdesk), leading to the exposure of customer information. The company was able to reproduce missing fields, as well as to apply translation and AI to build profiles of each user with the associated information.

Notably, last year, another prominent cryptocurrency exchange platform in Iran, Nobitex, was hit by a major cyberattack that resulted in the destruction of approximately USD 90 million in digital assets.

Resecurity interprets Ariomex as a shadow financial institution aligned with the Iranian regime. The company emphasizes that disrupting the financial flows linked to the Iranian regime and taking control of crypto exchanges serving malign interests should be among the strategic priorities to identify threat actors and their activity.

Spotify aims to provide a consistent listening experience that uses minimal data. As a result, your audio quality might be less than ideal, especially if you’re using a pair of high-fidelity headphones or high-end speakers. Here’s how to fix that.

Switch audio streaming quality to Very High or Lossless

The default audio streaming quality in both the mobile and desktop Spotify apps is set to Automatic, which usually keeps the audio quality at Normal, which is only 96 Kbps. Even though Spotify uses the Ogg Vorbis codec, which is superior to MP3, OGG files exhibit slight (but noticeable) digital noise, poor bass detail, dull treble, and a narrow soundstage at 96 Kbps.

Even worse, Spotify is aggressive about adjusting the automatic bitrate. Even though 4G is more than fast enough to stream high-quality OGG files, even with a weak signal, Spotify may still drop the quality to Low, which has a bitrate of just 24 Kb/s. You will notice such a sharp drop in quality, even on a pair of bottom-of-the-barrel headphones.

To rectify this, open the Spotify app, tap your user image, open “Settings and privacy,” and tap the “Media Quality” menu. Once there, set Wi-Fi streaming quality and cellular streaming quality to “Very high” or “Lossless.”

I recommend setting cellular streaming quality to Very high and reserving Lossless for Wi-Fi, since lossless streaming is very data-intensive. One hour of streaming lossless files can take up to 1GB of data, as well as a good chunk of your phone’s storage, because Spotify caches files you’re frequently streaming. Besides, you’ll struggle to notice the difference unless you’re listening to music on a wired pair of high-end headphones or speakers; wireless connection just doesn’t have the bandwidth needed to convey the full fidelity of Spotify lossless audio.

You might opt for High quality if you have a capped data plan, but I recommend doing so only if you stream hours upon hours’ worth of music every single day over a cellular network. For instance, I burn through about 8 GB of data per month on average while streaming about two hours of very high-quality music over a cellular network each day.

How Audio Compression Works and Why It Can Affect Your Music Quality

Feeling the squeeze when listening to your favorite song?

Set audio download quality to Very high or Lossless

If you tend to download songs and albums for offline listening, you should also set the audio download quality to “Very high” or “Lossless.” This setting is located just under the audio streaming quality section.

If you’ve got enough free storage on your phone, opt for the latter, but if you’d rather save storage space, set it to Very high. You’ll hardly hear the difference, but lossless files are about five times larger than the 320 Kb/s OGG files Spotify offers at its Very high quality setting, and they can quickly fill up your phone’s storage.

Adjust video streaming quality at your discretion

The last section of the Media quality menu is Video streaming quality. This sets the quality of video podcasts and music videos available for certain songs. Since I care about neither, I set it to “Very high” on Wi-Fi and “Normal” on cellular, but you should tweak the two options at your discretion because songs sound notably better at higher video streaming quality levels.

If you often watch videos over cellular and have unlimited data, feel free to toggle video quality to very high.

Make sure Data Saver mode is disabled

Even if your audio quality is set to Very high or Lossless, Spotify will switch to low-quality streaming if the app’s Data saver mode is enabled. This option is located in the Data saving and offline menu. Open the menu, then set it to “Always off,” or choose “Automatic” to have Spotify’s Data Saver mode kick in alongside your phone’s Data Saver mode.

You can also enable volume normalization and play around with the built-in equalizer

Last but not least, there are two additional features you can play with to improve your listening experience. The first is volume normalization, which sets the same loudness for every track you’re listening to. This can be handy because different albums are mastered at different loudness levels, with newer music usually being louder.

Since I’m an album-oriented listener, I keep the option disabled. I can just play an album and set the audio volume accordingly, and I don’t really mind louder songs when listening to playlists, artists, or song radios.

But if you can’t stand one song being quiet and the next rattling the windows, visit the Playback menu, enable “Volume normalization,” and set it to “Quiet” or “Normal.” The “Loud” option can digitally compress files, and neither Spotify nor I recommend using it. This also happens with “Quiet” and “Normal,” since both adjust the decibel level of the master recording for each song, but the compression level is much lower and extremely hard to notice.

Before I end this, I should also mention that you can access the equalizer directly from the Spotify app, where you can fine-tune your music listening experience or pick one of the available equalizer presets. If your phone has a built-in equalizer, Spotify will open it; if it doesn’t, you can use Spotify’s. On my phone (a Samsung Galaxy S21 FE), I can only use One UI’s built-in equalizer.

To open the equalizer, open “Playback,” then hit the “Equalizer” button. Now you can equalize your audio to your heart’s content.


Adjusting just a few settings can have a drastic impact on your Spotify listening experience. If you aren’t satisfied with Spotify’s sound quality, make sure to adjust the audio before jumping ship. You should also check the sound quality settings from time to time, as Spotify can reset them during app updates.​​​​​​​
