The game servers of Battle game have been taken offline over the weekend. The reason: Distributed Denial of Service (DDoS) attack.

The DDoS attack began at 5:30 a.m. when some of the players said they were unable to log in to the servers and play.

Even downdetector was also down, accordingly because Blizzard is monitoring the ongoing attack.

The recent outage is not the first time for Blizzard. Their servers have gone offline for three times already, including the recent incident.

Blizzard's latest issue have caused the problems for gamers playing Overwatch, Hearthstone: Heroes of Warcraft, and Diablo 3

"We are currently monitoring a DDoS attack against network providers which is affecting latency/connections to our games," confirmed the hacking group PoodleCorp who claimed responsibility for the attack.

PoodleCorp stopped the DDoS attack as soon as their tweets have been shared 3,000 times.

Battle.net  also experienced a number of technical issues on Sept. 13 and 16. This caused difficulty in people logging into the game servers.

The condition was same as before: The hackers will only stop the attack if their tweets will be retweeted 2,000 times.

The gamers did as instructed, and the attacks have stopped.

PoodleCorp confirmed that the next attack will be on servers running Battlefield on Oct. 21.

"Increasingly these are extortion-related, but this is somewhat irrelevant when an attack actually strikes. Whether for financial gain, or purely for notoriety, the end result is still the same and the unlucky target just wants to get back online as soon as possible," said Sean Newman, Director of Corero Network Security

According to Newman, more organizations, especially the ones relying on high levels of online availability, are now being subjected to DDoS attacks for different reasons.

It is still unclear why the hacking groups is repeatedly attacking Blizzard. One thing is for sure, the gaming world is not happy about it.
