San Francisco Metro System Hacked with Ransomware; Resulting in Free Rides
Nothing is immune to being hacked when hackers are motivated.
The same proved by hackers on Friday, when more than 2,000 computer systems at San Francisco's public transit agency were apparently got hacked.
San Francisco's Municipal Transportation Agency, also known as MUNI, offered free rides on November 26th after MUNI station payment systems and schedule monitors got hacked by ransomware and station screens across the city started displaying a message that reads:
"
You Hacked, ALL Data Encrypted. Contact For Key(cryptom27@yandex.com)ID:681 ,Enter."
According to the San Francisco Examiner, MUNI
confirmeda Ransomware attack against the station fare systems, which caused them to shut down ticket kiosks and make rides free this weekend.
As you can see, the above message delivered by the malware followed by an email address and ID number, which can then be used to arrange ransom payments.
MUNI Spokesman Paul Rose said his agency was investigating the matter and "working to resolve the situation," but did not provide details as of how MUNI got hacked.
"
We are currently working to resolve the situation," said Rose.
"There is an ongoing investigation, and it wouldn’t be appropriate to provide additional details."
Trains themselves were not affected by the malware attack, and the MUNI claimed that the payments were resumed on the morning of November 27th. The MUNI looks after trains, trams and buses around the city, including San Francisco's iconic cable cars.
It is yet not clear exactly who was responsible for the attack (besides a pseudonym "Andy Saolis"), but according to local media reports, the agency's computers were being held by ransomware until the MUNI paid the equivalent of more than $73,000 in Bitcoin.
Andy Saolis is a pseudonym commonly used in
HDDCryptor ransom attacks, which uses commercial tools to encrypt hard drives and network shares on Windows machines using randomly generated keys and then overwrite the hard disks' MBRs to prevent systems from booting up properly.
The target machine is typically infected by accidentally opening a malicious executable in an email or download, and then the malware spreads out across the network.
The email address, cryptom27@yandex.com, used by anonymous criminal points the city to a Russian email address to arrange payment and has been linked to other cyber attacks as well.
When reaching at the provided email, the hacker provided a statement in broken English, which read:
"We don't attention to interview and propagate news! Our software working completely automatically and we don't have targeted attack to anywhere! SFMTA network was Very Open and 2000 Server/PC infected by software! So we are waiting for contact any responsible person in SFMTA but I think they don't want deal ! so we close this email tomorrow!"
The same email address, cryptom27@yandex.com, was linked to a ransomware strain called
Mambain September. The ransomware employs tactics similar to those demonstrated against the MUNI systems.
Not much about the hack is known; the extent of the hack and hacker's identity remain a mystery for now, but the incident once again reminds us that how vulnerable our critical infrastructure remains.
