The U.S. is preparing for a possible wave of computer attacks targeting banks and companies by hackers connected to the regimes in Syria or Iran. The interference is expected in retaliation for any military strike against the government of Bashar al-Assad. Banks have been a main target for hackers since last September, causing them to heighten their security, according to Bloomberg:

While U.S. intelligence reports say the capability of the Syrian hackers is limited, state-linked hackers in Iran, an Assad ally, have been probing U.S. critical infrastructure companies in recent months, finding vulnerabilities to be exploited later, said James Lewis, a fellow in cybersecurity at the Center for Strategic and International Studies.

The Homeland Security Department “is closely following the situation and actively collaborates and shares information” with companies and other agencies in response to evolving cyberthreats, Peter Boogaard, a DHS spokesman, said in an e-mailed statement.
