PWNED

Misaligned incentives led to an intractable argument

Welcome back to PWNED, the column where we talk about companies and organizations that leave the doors wide open to attackers. This week’s sad story involves a major American pharmacy chain that couldn’t fill a prescription for password security.

Our tale comes courtesy of red team and pen testing specialist Dahvid Schloss, who currently serves as COO of Suzu Labs , a cybersecurity company that boasts “we break your systems before adversaries do.” Over a career spanning more than 15 years, Schloss has assessed the security of numerous businesses, including a large US pharmacy retailer that he asked us not to name. He wasn’t asked to break in, just to do an audit on all of the org’s corporate switches, routers, and firewalls.

“So, I come across this firewall,” Schloss said. “That is an edge firewall, meaning this is what touches the internet. This part will add its enable password, which is the term Cisco uses for administrator. It had the enable password as 'password.' Just p-a-s-s-w-o-r-d.”

As Schloss noted, the enable command on Cisco devices allows the user to gain administrative rights to the firewall, controlling network traffic. If someone connected to that firewall, either via SSH or through an exploit, and got normal user privileges, they could then elevate those privileges to admin and do something like shut off all traffic from the intranet to the outside world.

Schloss actually didn’t guess that the password was “password,” but instead was able to decrypt the file holding the passwords by breaking Cisco’s own protection, something he said is easy to do.

“That enable password was stored as Cisco IOS type 7, which isn’t really a hash,” he said. “It’s more of a reversible encoding with a publicly known key. Even back then, it was best practice not to use it.”

But even if the password were stored in a secure place, it would be very easy for a threat actor to guess. So he marked the password failure down as a “high find,” a bad type of vuln that needs to be fixed right away.

When he brought the password to the company’s auditing department, they put him on a phone call with the auditing team, the entire IT team, his own manager, and others. On the packed call, the auditing team, who had commissioned Schloss’s work, was very concerned about the firewall password, but the IT team didn’t think it was a very serious problem. The two sides screamed at each other for more than an hour while Schloss and his colleagues sat there quietly, staring at their cameras.

“The audit team is like ‘yeah, we gotta fix this.’ And the directors were really harping on ‘this needs to be done’ and the IT team starts firing back,” Schloss explained. “It’s like ‘Why? Who’s gonna? What does it matter? No, this isn’t a high-priority find. This is maybe a medium. Yeah, it’s bad, but it’s not that bad.’”

The call dragged on so long that Schloss was unable to finish presenting his findings and recommendations. The conflict was so severe that the client continued to follow up and ask him to explain what he found again for the next three years – long after he had moved on to other projects.

He later learned that the auditing department controlled the bonuses for the IT team and there was a stipulation that any “high finding” would eliminate those bonuses. So they weren’t just arguing about “password” - they were really talking about the compensation for an entire division.

The lesson here is more than “don’t use the word ‘password’ as a password.” It's also about misaligned incentives. Tying security posture to compensation seems like a good way to incentivize workers to follow best practices, but it also leads them to deny responsibility and minimize mistakes when they're found. ®
