The group also appears robust, bouncing back despite the efforts of U.S. authorities and Twitter to suspend its activities.
And Noman has noted an evolution in the Syrian Electronic Army's methods over time.
Early attacks focused on apparently irrelevant websites, but later efforts shifted first toward compromising the Facebook pages of organizations seen as hostile to the Syrian government, and now high-profile Twitter accounts.
"They demonstrate interest in disrupting the flow of information, especially the flow of information from international media," Noman said of the group.
This is not surprising because it is in line with what the Syrian government itself has tried to do, in accusing the regional and international media of being biased against it, he said.
Tuesday's attack on the AP Twitter feed shows "an escalation in depth but not in scale," Noman said.
While the Syrian Electronic Army has compromised the Twitter accounts of several international media organizations before, the kind of message sent to the AP feed was more disturbing.
The attack on BBC Weather's Twitter feed, for example, was hard to take seriously. "Syrian Electronic Army Was Here," read one tweet. "Saudi weather station down due to head-on collision with camel," said another.
Others were more inflammatory -- "Hazardous fog warning for North Syria: Erdogan orders terrorists to launch chemical weapons at civilian areas" -- but still not credible.
What is worrying about the AP Twitter hack is that next time there is breaking news on Twitter, people will wonder if it's true or just another compromise, Noman said.
It's a warning to everyone to step up their own online security measures -- and be aware that not all they read may be true.
