In March 2020, KrebsOnSecurity alerted Swedish security giant Gunnebo Group that hackers had broken into its network and sold the access to a criminal group which specializes in deploying ransomware. In August, Gunnebo said it had successfully thwarted a ransomware attack, but this week it emerged that the intruders stole and published online tens of thousands of sensitive documents — including schematics of client bank vaults and surveillance systems.
The Gunnebo Group is a Swedish multinational company that provides physical security to a variety of customers globally, including banks, government agencies, airports, casinos, jewelry stores, tax agencies and even nuclear power plants. The company has operations in 25 countries, more than 4,000 employees, and billions in revenue annually.
Acting on a tip from Milwaukee, Wis.-based cyber intelligence firm Hold Security, KrebsOnSecurity in March told Gunnebo about a financial transaction between a malicious hacker and a cybercriminal group which specializes in deploying ransomware. That transaction included credentials to a Remote Desktop Protocol (RDP) account apparently set up by a Gunnebo Group employee who wished to access the company’s internal network remotely.
Larsson quotes Gunnebo CEO Stefan Syrén saying the company never considered paying the ransom the attackers demanded in exchange for not publishing its internal documents. What’s more, Syrén seemed to downplay the severity of the exposure.
“I understand that you can see drawings as sensitive, but we do not consider them as sensitive automatically,” the CEO reportedly said. “When it comes to cameras in a public environment, for example, half the point is that they should be visible, therefore a drawing with camera placements in itself is not very sensitive.”
It remains unclear whether the stolen RDP credentials were a factor in this incident. But the password to the Gunnebo RDP account — “password01” — suggests the security of its IT systems may have been lacking in other areas as well.
