While the concept of archiving chats is benign, searching for and downloading a pre-packaged "Telegram-csv.rar" file from the internet—especially from forums, file-sharing sites, or the dark web—carries severe risks.
In the vast ecosystem of file sharing, encryption, and data management, certain filenames begin to circulate in niche communities, often causing a mix of curiosity and concern. One such filename that has recently gained attention is .
When you request a data export from Telegram Desktop (Settings > Advanced > Export Telegram Data), the application may generate one or several CSV files containing your contact list—names, phone numbers, and user IDs.

Once a user extracts and runs the contents, the malware—often a variant of or similar info-stealers—performs several tasks: Session Hijacking
Security researchers have flagged archives with similar naming conventions (e.g., Telegram-csv.rar ) as carriers for . Once the victim runs the malicious content, the malware:
: Attackers often frame the file as a "contact list," "leak," "crypto database," or a "backup" of a specific group's members. By using the label inside a : Frequently, the first thing a hijacked account
Therefore, a file is essentially a compressed archive containing a structured text database of Telegram messages or user data. It turns a fluid, real-time chat interface into a static, analyzable dataset.
: It scans the system for sensitive information, including saved browser passwords, cookies, and Steam credentials. Self-Propagation
If the archive contains a script (like .py ), review it for malicious calls to external servers. One such filename that has recently gained attention is
Developers building Telegram Bots often export user data (with consent) to CSV files for analytics. For example, a poll bot might record votes in a CSV, or a customer support bot might export chat transcripts. Those developers may package multiple CSV exports into a RAR archive, naming it Telegram-csv.rar for organization.
