What's up with the Anonymous hackfest?

"Security of our customers' data is the top priority at PayPal. We're aggressively investigating this but to date we have been unable to find any evidence that validates this claim," a PayPal spokesperson said.

In a blog post on Sunday, VMware said it became aware of ESX source code that had been published online, which it says dated back to 2004 and is related to source code that had been leaked in April.

The leak was officially announced on Twitter by user STUN, who links Anonymous to the breach when announcing the leak.

VMware said more related files could be released as well. "As a matter of best practices with respect to security, VMware strongly encourages all customers to apply the latest product updates and security patches made available for their specific environment," wrote VMware Director of Platform Security Iain Mulholland, adding a recommendation for customers to review security hardening guidelines posted by VMware. Additional requests for comment form VMware on Monday regarding the situation were not responded to.

Jon Oltsik, an ESG senior principal analyst, says the newest release of ESX code raises the risk exposure for customers. Patches and service bulletins should be monitored closely in the coming days by concerned users. "Even though the source code is old, some of it is likely the foundation of modern day ESX," he says. "Cybercriminals now have a recipe for potential vulnerabilities to research and exploit. I would imagine a spike in VMware-focused malware as a result."

Oltsik recommends that customers assess their data center securities at both the network and host-based levels for things like network segmentation and ACLs, and ensure that security controls such as firewalls, IDS/IPS and WAF are all up to date. As a precaution, customers can also block access to data center VMs that don't need to be accessed over public networks.

VMware, meanwhile, needs to do its due diligence as well. "VMware needs to be extremely visible with security even if this turns out to be a non-issue," Oltsik says. "There are a lot of nervous folks out there."
