Counterfeit Cisco equipment were powering the failure of an IT company’s network switches past slide after a software upgrade, an investigation has discovered.
Underscoring the security troubles posed by counterfeit hardware, the authentic-lifetime anecdote prompted the victimized purchaser to fee F-Secure’s hardware security crew to conduct a extensive evaluation of the components.
The enterprise found out that two variations of Cisco Catalyst 2960-X series switches turned out to be fake and not authentic gadgets manufactured by Cisco. The counterfeits did not have any backdoor-like functionality, but were made to idiot security controls, F-Secure, said in a report introduced these days.

“We found that the counterfeits had been developed to bypass authentication measures, but we didn’t come across proof suggesting the models posed any other risks,” said Dmitry Janushkevich, a senior consultant with F-Safe Consulting’s Components Security staff, and direct writer of the report. “The counterfeiters’ motives were likely limited to building funds by selling the devices. But we see motivated attackers use the exact type of approach to stealthily backdoor companies, which is why it is vital to thoroughly check out any modified hardware.”
The counterfeits ended up physically and operationally similar to an reliable Cisco swap. One unit’s engineering suggests that the counterfeiters both invested closely in replicating Cisco’s original design or had accessibility to proprietary engineering documentation to help them generate a convincing copy.
Typically, copies are marketed at a fraction of the price tag of the serious matter to unsuspecting consumers wondering they received a wonderful deal, but in performing so, could compromise the organization’s general security posture.
The F-Safe report observed that Cisco employs a dedicated Brand name Safety group, whose objective is to protect towards counterfeit and gray sector activities. The crew partners with customs teams and regional governments all more than the planet. In April 2019, they seized $626,880 worth of counterfeit Cisco solutions in a single working day. Nevertheless, regardless of prosperous operations, Cisco has not been able to end fraud entirely, F-Secure pointed out. One unit dissected by F-Protected exploited what the investigate workforce thinks to be a beforehand undiscovered computer software vulnerability to undermine secure boot procedures that provide security against firmware tampering.
“Security departments can not pay for to overlook components that is been tampered with or modified, which is why they need to have to investigate any counterfeits that they’ve been tricked into applying,” claimed Andrea Barisani, F-Safe Consulting’s Head of Hardware Security.
“Security departments just cannot manage to ignore components that is been tampered with or modified, which is why they have to have to examine any counterfeits that they’ve been tricked into making use of,” Barisani described. “Without tearing down the components and examining it from the floor up, companies can not know if a modified machine experienced a larger sized security affect,” she extra.
Dependent on the situation, the impression can be key plenty of to fully undermine security steps intended to secure an organization’s security, procedures, infrastructure.
F-Protected delivered the following advice to assistance corporations reduce by themselves from applying counterfeit devices:
- Supply all your devices from approved resellers.
- Have crystal clear interior procedures and guidelines that govern procurement processes.
- Guarantee all devices run the most recent available software program offered by vendors.
- Make note of even actual physical variances involving diverse models of the same merchandise, no make a difference how refined they may possibly be.
