The person claiming responsibility for the attack on San Francisco’s MUNI says the SFMTA has lax security, and warns that if the ransom isn’t paid, they’ll release 30GB of compromised data.
The demands follow a weekend of headaches for SFMTA, after MUNI was targeted shortly before the Thanksgiving holiday, resulting in systems that were encrypted and held for a $73,000 ransom.
On Sunday, Salted Hash revealed that 2,112 MUNI systems were infected with hard drive encrypting malware. The person responsible for the attack, who maintains a Yandex email account that has been linked to similar incidents, demanded 100 Bitcoins for the decryption keys, or just over $73,000 USD.
While more than 2,000 systems were compromised by the malware, 8,656 systems were exposed to the attacker, and it still isn’t clear why they were not compromised as well.
Shortly after the attack, SFMTA started allowing passengers to ride light rail free of charge, in order to minimize customer impact, as the malware impacted desktops, laptops, servers, and other critical systems.
SFMTA hasn’t responded to questions about the incident, and there are mixed reports of systems being restored to working order in some areas.
Given that ransom hasn’t been paid, and hard drive encrypting malware such as this can’t be defeated by basic restoration from backups (in most cases you'll have to re-image the drive), it is possible SFMTA / MUNI administrators have begun replacing or imaging hard drives.
On Monday afternoon, the owner of the Yandex email account reached out to Salted Hash and expressed frustration over the lack of payment, given how much money MUNI earns each day from passengers. The email also expressed frustration over what is considered to be a poor stance on network security by SFMTA.
The message, printed in full below with no edits, goes on to warn that if payment isn’t made, such inaction will trigger the release of 30GBs of compromised data, allegedly taken during the hack that exposed the MUNI network to the cryptor malware.
