Hackers aligned with Anonymous claim to be carrying out numerous cyberattacks against North Korean websites, urging North Korean citizens to rise up against their "oppressive" government.

Hackers also claim to have seized over 15,000 passwords belonging to accounts on Uriminzokkiri.com, an outward-facing North Korean website hosted on China-based servers.

The hackers, calling themselves Anonymous Korea, say they have launched numerous distributed denial of service (DDoS) attacks against North Korean websites — including www.airkoryo.com.kp, www.naenara.com.kp, www.korea-dpr.com and www.friend.com.kp — since Saturday. However, a prominent hacker known as The Jester has also claimed responsibility for the attack.

Anonymous Korea’s Twitter and Facebook logos both include a South Korean flag.

US bank Wells Fargo suffered online service interruptions Tuesday during periods of unusually high web traffic volumes originating from a denial-of-service (DoS) cyberattack.

Wells Fargo spokeswoman Bridget Braxton confirmed to Reuters that the bank’s website and online banking services were disrupted but did not specify where the attacks came from.

"The vast majority of customers are not impacted and customer information remains safe," Braxton said. 

Muslim hackers, part of a group known as the Izz ad-Din al-Qassam Cyber Fighters, claimed responsibility for the attack as part of the group’s ongoing campaign against US-based financial institutions. 

On Syria’s digital battlefield, hackers loyal to Syrian President Bashar al-Assad are defeating the rebels' cyber militias.

Just as the Syrian opposition leans on the West to supply weapons and other military aid, rebel hackers depend on the international community to help bolster their tactics.

But even as the conflict reaches new stages of violence – more than 70,000 people have been killed so far – support among international hacker communities is waning.

Last year, rebels enjoyed massive support from international hacker collectives like Anonymous, which launched several attacks on the Assad government. Early in 2012, Anonymous said it accessed several regime email accounts, including an account belonging to the Syrian president. Anonymous renewed their pledge to support Syrian hackers last November as the Assad regime threatened to shut down internet access across the country.

But after several arrests and convictions, Anonymous’ OpSyria seems to have ground to a halt. Without wider international support, Assad's Syrian Electronic Army’s dominion in the Syrian internet war is all but unchallenged.

In recent weeks, the Syrian Electronic Army has launched a number of successful campaigns, seizing control of social media accounts belonging to a broad range of news organizations and nonprofit foundations. The Syrian Electronic Army says western news organizations are outlets for Syrian rebel propaganda.

Reuters deputy social media editor Matthew Keys, who could be facing up to 25 years in prison for helping the hacker collective Anonymous, has gained the sympathy of online activists who say he is another victim (like online activist Aaron Swartz) of legal bullying by federal prosecutors.

Keys was indicted on Thursday afternoon, with the Department of Justice alleging that Keys handed over log in credentials for administrator access KTXL Fox 40 in Sacramento to Anonymous. The credentials had been provided to him while working for Fox 40, which is owned by Los Angeles Times parent company Tribune Co.

The indictment alleges that using the name “AESCracked” in an Anonymous internet relay chat (IRC), Keys handed over user names and passwords to hackers, granting them access to administrator accounts for LAtimes.com.
