SpiderPery Ransomware

SpiderPery is a newly identified ransomware strain discovered in early July 2025. It belongs to the crypto‑virus family and encrypts victim files by appending the .SpiderPery extension. Once encryption is complete, it delivers a ransom note instructing victims to contact the attackers via Telegram at @spiderPrey or SpiderPery.

Threat Evaluation

How I Got Infected

SpiderPery ransomware typically spreads through malicious attachments in phishing emails, pirated software downloads, and deceptive ads that push users to install infected files. If you recently downloaded or opened a suspicious file, that is likely how the infection occurred.

---

What Does It Do

After execution, SpiderPery silently encrypts user files and changes their extensions to .SpiderPery. The malware then drops a file named ReadMe.txt in multiple directories. This ransom note contains instructions for reaching out to the threat actors via Telegram. The ransomware may also delete shadow copies and disable system recovery tools to prevent easy restoration.

---

Should You Be Worried?

Yes. SpiderPery is a high-severity ransomware threat that renders your data inaccessible without a decryptor. There is no known public decryption tool at the time of writing. Paying the ransom is strongly discouraged as it may not result in file recovery and only fuels further criminal activity.
