The WVOASIS Twitter account usually posts links to the group's Facebook account, which mostly includes photos and videos of employees training to use the new computer system.
Neither account is very popular. The Facebook page has only 130 likes, while the Twitter page had only 16 followers as of Monday evening.
A quick Google search turned up multiple, apparently unrelated Twitter accounts posting identical jokes and links as the ones featured in the WVOASIS tweets, which could point to hackers.
Chris Vance, a digital forensics specialist at Marshall University's Forensic Science Center, said it's difficult to guess how or why WVOASIS's account would be hacked.
"It's hard to say, because there's a lot of ways it could happen. In most cases, when a Twitter account is compromised, it's probably due to a weak password," he said.
Accounts also can be hacked by viruses or other malicious software, which could have invaded a user's computer or smart phone and snaked its way to the Twitter account.
"Say you have 20 people that can post to this Twitter feed. If one of these people's phones are compromised, that password is known," he said.
He said the best way to avoid being hacked is to limit access to accounts, and keep track of who is authorized to post on them. Vance also recommends using strong passwords that do not include any biographical information, and changing those passwords often.
Attacks on Twitter accounts are not uncommon. In late April, The Associated Press's official account was compromised and tweeted a fraudulent breaking news alert claiming there had been explosions at the White House and President Barack Obama was injured.
The account was shut down moments later, and The AP confirmed it had been hacked.
