Businesses are being warned of a new malware that infects networks by masquerading as a legitimate email from BlackBerry, which has been uncovered by the Websense ThreatSeeker Network.
The malware is reportedly spread via fake emails claiming that the recipient has successfully created a BlackBerry ID.
The email includes a message urging the recipient to download a malicious file housing the malware.
Downloading and running the attachment reportedly allows the hackers to drop other executable files and modifies the system registry, making it automatically run malware programs when the system starts.
"This email is piggybacking on BlackBerry's reputation, knowing that many corporate users will be targeted," Websense researcher Elad Sharf told V3.
"Like any malware, this puts any compromised machine out of the sole control of its lawful users and under the additional control of cyber criminals, putting corporate data at risk."
The cyber scam is particularly clever as its uses a message that is a copy-and-pasted version of a legitimate email from BlackBerry.
The full impact of the BlackBerry scam is not known and there are currently no firm numbers regarding how many machines it has successfully infected.
Research in Motion's BlackBerry ecosystem is favoured by many businesses for its strong security software.
The new malware doesn't actually target the BlackBerry OS itself, unlike the recently discovered Zeus variant plaguing the ecosystem.
