Troj/JSRedir-HY is a JavaScript Trojan that is included in a Blackhole malware attack, which spreads on Twitter using 'It's you on photo?' trickery. However, versions of the malicious spam attack using the wording 'It's about you?' have also been spotted on Twitter. An example of the dangerous tweets is '@[Username] It's you on photo? [Domain]/#[Username].html'. Malicious links on Twitter state that you are pictured in an online photo. The accounts that are spreading the messages have either been hijacked by cybercriminals or have been created with the aim of spreading dangerous links. The malware at the end of the link is detected as Troj/JSRedir-HY. The script diverts to an IP address that itself diverts to a .CU.CC domain, to load an executable code, which is detected as Troj/Agent-XES, and finally reroute to a .SU domain that includes the Blackhole exploit kit.
