Researchers at Kaspersky have identified a new cyber threat disguised as torrents, with the notorious Efimer trojan at its core. This malicious software is actively attempting to infiltrate users' cryptocurrency wallets by disguising itself as legitimate torrent downloads. The criminals behind Efimer exploit inadequately protected websites, particularly those powered by WordPress, to distribute these dangerous files.
These files often present themselves as newly released movies. However, once downloaded, the torrent contains a malicious file, camouflaged as a media player executable named
Phishing Campaigns Targeting Companies
In addition to individual users, companies have also become targets of this cyberattack. The perpetrators dispatch phishing emails filled with false accusations of copyright infringement. Included in these emails is an archive file claiming to contain details about these supposed violations. In reality, however, it harbors the Efimer trojan, ready to execute once opened.
Upon activation, Efimer begins searching through the victim's device for strings that resemble seed phrases, which are critical for accessing cryptocurrency wallets. The trojan manipulates these transactions, redirecting funds to the attackers' own cryptocurrency addresses instead.
Global Reach and Growing Threat
The impact of Efimer has already been felt on an international scale, with Kaspersky reporting victims in Russia, India, Spain, Italy, and Germany. The number of affected users continues to rise as the distribution of this malware spreads. This global reach underscores the need for increased vigilance and robust cybersecurity measures.
This incident is reminiscent of previous attacks, such as SparkKitty, which targeted iOS and Android platforms in Southeast Asia and China to similarly pilfer cryptocurrency from unsuspecting users. These threats underline the ongoing efforts by cybercriminals to exploit digital financial systems, highlighting the importance of security awareness and proactive measures to safeguard against such activities.
