Reviews of ISIS cyber capabilities (including its jihad helpdesk and cyber operations manual) continue, with derision from Wired, Krebs, and others. Reviews of ISIS information operations, however, are much less derisive: here, at least, the Caliphate is regarded as displaying considerable marketing savvy (and information operations are essentially marketing in battledress). The messaging is brutal in the extreme — do remember, in the face of the temptation to regard the Internet with the disinhibition appropriate to video games, that actual murder is committed therein — but its appeal to the target demographic seems undeniable. Much of the carnage ISIS commits is done with an eye to messaging (and many observers see rival Al Qaeda's strike in Mali last week as an attempt to regain terrorist mindshare).

It's proving difficult to move ISIS off social media accounts, pace the large claims of Anonymous, which Ars Technica sees as conducting a predictably indiscriminate campaign of account reporting.

Someone claiming to represent Anonymous warned of massive ISIS terror actions Sunday. These didn't materialize, and Anonymous says it doesn't know who issued the warnings. Other adherents of the collective claim to have attacked German media (for showing Anonymous insufficient respect) and Japan's Health Ministry (for unclear reasons). It's only fair to note the difficulty of crediting an anarchist collective with policy or programs, as distinct from shared sympathies, so criticisms of Anonymous for lack of focus may be harshly founded on unreasonably high expectations.
