Fake installers of the Telegram messaging app are being distributed online that injects Windows-based ¡®Purple Fox¡¯ backdoor on compromised systems.
According to researcher Natalie Zaragov, they've come across a large number of malicious installers delivering the same ¡®Purple Fox¡¯ rootkit version using the same kind of attack chain. The file has been distributed via email, or from phishing websites.
Zaragov explains, "The beauty of this attack is that every stage is separated to a different file which is useless without the entire file set. This helps the attacker protect his files from AV (anti-virus) detection."
During the investigation, researchers saw the infected file was able to leave most parts of the attack under the radar by separating the attack into several small files, most of which possessed low detection rates by antivirus software and the final stage progressing to Purple Fox rootkit infection.
