Anonymous and several other hacking groups are planning to attack the US Government and Banking Infrastructure on May 7, 2013.
I added a threat briefing on OpUSA, what's being targeted, and by who, to my Threat Watch site.
Currently, the only named targets of this attack are Whitehouse.gov, FBI, and Bank of America. However, I'm sure other targets will be included.
If you work for a government agency, or in the banking agency, be vigilant, and be on the lookout for highly targeted phishing attacks.
You can read the full briefing at my Threat Watch site.
