Twitter's account hacking woes aren't about to end any time soon.

Days after a number of prominent Twitter accounts got hacked — including those belonging to musicians Katy Perry and Drake as well as Twitter co-founder Evan Williams — nearly 33 million Twitter usernames and passwords are being sold online.

According to LeakedSource, a site that collects databases of stolen login credentials for a number of sites, the 32,880,300 Twitter credentials are being sold by a person identified by the alias Tessa88. Zdnet reported that the price Tessa88 is asking for the entire database (which allegedly contains 379 million records, but likely has many duplicates) is 10 bitcoins, or about $5,800 at the time of writing.

Each record consists of one or two email addresses, username and password, but what's odd about this leak is that the passwords aren't encrypted at all. While this is bad news for users whose credentials are now available online (Leakedsource says it checked the authenticity of the passwords with 15 users, all of which confirmed they were genuine), this indicates that they were not obtained by hacking Twitter or a third-party site.

"The explanation for this is that tens of millions of people have become infected by malware, and the malware sent every saved username and password from browsers like Chrome and Firefox back to the hackers from all websites including Twitter," Leakedsource wrote in a blog post Wednesday.

Leakedsource lets anyone search through its database of stolen login credentials, but we advise caution, as any email addresses or other info entered into the search field could be harvested for nefarious purposes. You can, however, check Leakedsource's list of the most commonly used passwords from its Twitter database — if your password (on any site, not just Twitter) resembles anything on that list, you should probably change it as soon as possible.

"123456," "qwerty" and "password" are not good passwords. An analogy to using these would be locking your front door, but then leaving keys on your porch. And breaking the lock. And punching a big hole in the door. Image: Leakedsource

On its support account, Twitter said it's taking steps to protect users that may have been affected by the recent password leaks.

To help keep people safe and accounts protected, we've been checking our data against what's been shared from recent password leaks. — Twitter Support (@Support) June 6, 2016

And Twitter security officer Michael Coates tweeted Thursday that the company is confident its systems have not been hacked.

We securely store all passwords w/ bcrypt. We are working with @leakedsource to obtain this info & take additional steps to protect users. — Michael Coates ஃ (@_mwc) June 9, 2016

TechCrunch notes that the passwords Leakedsource has obtained might simply be old passwords that are circulating on the dark web. Be that as it may, you should make sure your Twitter account is safe, your password is hard to break, and turn on two-factor authentication. Here's our advice on how to toughen the security of your online accounts.
