Teacher: Now, understand the problem? Solve this instance: SACRAMENTO (CBS13) — Sacramento Regional Transit is the one being taken for a ride on this night, by a computer hacker. 
  
 That hacker forced RT to halt its operating systems that take credit card payments, and assigns buses and trains to their routes. 
  
 The local transit agency alerted federal agents following an attack on their computers that riders may not have noticed Monday. 
  
 “We actually had the hackers get into our system, and systematically start erasing programs and data,” Deputy General Manager Mark Lonergan.

 Inside RT’s headquarters, computer systems were taken down after the hacker deleted 30 million files. 
  
 The hacker also demanded a ransom in bitcoin, and a left a message on the RT website reading “I’m sorry to modify the home page, I’m good hacker, I just want to help you fix these vulnerability.” 
  
 Bitcoin has risen sharply in the last year from around $1,000 in December to more than $8,000 on Monday. 
  
 Ryan Eldridge is the founder of the company called “Nerds on Call.” 
  
 “I would say they’re probably young, because they just want to show off,” Eldridge said.

 Eldridge says the hacker will likely find an online forum to take credit for the hack, and that they may not be local. 
  
 “The person who hacked it may have simply had an exploit that he was running in the background on his machine, and then got a hit, ‘Hey RT is available to be hacked,'” Eldridge said. 
  
 RT claims it managed through the trouble, without a significant slow down for riders, and that no employee or customer identities were stolen. ||||| Click here for the Capitol March for the Dream and Diversity Expo Free Ride Flyer Each year, thousan ..Read More ||||| The secure Sacramento Regional Transit website was still down Tuesday morning, the result of a weekend hack in which ransom reportedly was demanded in the form of bitcoin. 
  
 The agency said in a Facebook post that it was working with the federal Department of Homeland Security to resolve the cyberattack. 
  
 “Fortunately, the damage to our network was limited, and no personal data was compromised,” SacRT said in its social media post. “This was only an attack on our business operations in an effort to extort money. SacRT’s IT team is working to restore the network, but the website will remain off-line until the entire system has been scrubbed for malware. As our IT team verifies applications and services are ‘safe’ they will be brought back online. ... Light rail and bus operations have not been impacted, but passengers will be unable to retrieve schedule information until the website is brought back online. We thank you in advance for your patience as we work through this challenge.” 
  
 The Sacramento Bee reported: “The hackers announced their presence on Saturday when they ‘defaced’ the agency’s main webpage, putting up a note saying, ‘I’m sorry to modify the home page, i’m good hacker, i I just want to help you fix these vulnerability. This is one of the loopholes, modify the home page ...’ 
  
 That message turned out to be a trap, SacRT Chief Operating Officer Mark Lonergan told The Bee. When technicians went into the SacRT system to check out the damage, it unleashed the attack Sunday morning that erased the virtual servers. 
  
 The hacker or hackers sent a Facebook message to SacRT Sunday morning demanding one bitcoin, currency whose worth soared above $8,000 on Monday. SacRT did not respond to that demand. 
  
 Lonergan said light rail and buses continue to run on a normal schedule. The trains and buses are run under control of an operator, with minimal automation, he said. 
  
 He said technicians estimate it could be several days before the agency’s system is fully restored. The agency then plans to bring in an expert “to review our vulnerabilities and make this less likely to happen again,” Lonergan said. 
  
 Some functions were available on the website today. ||||| A hacker has attacked and crippled the Sacramento Regional Transit (SacRT) system for a ransom of 1 Bitcoin, or about $8,000 at today’s market value. The attack erased important programs that are necessary for planning and dispatching bus routes, as well as dispatching employees for service. 
  
 In an odd move, the hacker demanded a single Bitcoin in order to stop making the attacks and to allow the computer team at SacRT to get the system back online. According to a message sent by the hackers: 
  
 “Hello, I will always attack your website, we are hackers. We can do everything. Pay us now to stop attacking.” 
  
 The hack raised awareness and SacRT removed all its credit card payment options until full security can be achieved. It may take several days to get the system back online to complete functionality. 
  
 The hack and ransom are odd in that the demands are so small. Other hacks this year include sizable amounts. HBO, Wipro, and Equifax all faced ransoms anywhere from $250,000 to over $75 mln. It appears the SacRT hacker can be bought off for a relatively small amount, though nevertheless causing much disruption. ||||| Computer hackers directly attacked the Sacramento Regional Transit system computers this weekend, erasing data and threatening to do more harm if SacRT doesn’t pay them one bitcoin, now worth about $8,000. 
  
 The attack erased parts of computer programs on the agency’s servers that affect internal operations, including the ability to use computers to dispatch employees and assign buses for routes, chief operating officer Mark Lonergan said. 
  
 Regional Transit officials said they have determined that no data was stolen and are working to secure their system from further attack. Bus and rail service has not been affected. 
  
 The agency took down its web homepage for customer information and shut down its systems for processing credit card payments on Connect Cards until agency officials can add security to prevent hackers from getting into SacRT’s computer system in the future.

 The agency’s mobile fare app, which is on a separate cloud-based system, remains fully operable, Lonergan said, including allowing users to add fare value to the app. 
  
 Agency technicians were using backed up data to refresh internal systems on Sunday and Monday, Lonergan said. 
  
 SacRT had not yet notified police of the crime Monday morning, but planned to, he said. 
  
 The hackers announced their presence on Saturday when they “defaced” the agency’s main webpage, putting up a note saying, “I’m sorry to modify the home page, i’m good hacker, i I just want to help you fix these vulnerability. This is one of the loopholes, modify the home page ...”

 The hacker or hackers sent a Facebook message to SacRT Sunday morning demanding ransom, with the message, saying, “hello, I will always attack your website, we are hackers. we can do everything. Pay us now to stop attacking.” 
  
 The hackers asked for a bitcoin – whose worth soared above $8,000 on Monday. SacRT did not respond to that demand. Lonergan said the agency’s security systems had already noticed that data was being erased. 
  
 “We caught it early (Sunday) morning,” he said. “We took all our systems offline” and determined what data had been erased. “We are restoring everything now and bringing it up online.” 
  
 Lonergan said the agency was able to track how the hackers entered the system, and what the hack was doing. “That is how we know no data exited,” he said. “This was about destruction.” 
  
 The agency’s system has suffered from virus and malware attacks in the past, but had never suffered an attack that destroyed data. 
  
 Lonergan said light rail and buses continue to run on a normal schedule. The trains and buses are run under control of an operator, with minimal automation, he said.

Riders and officials of the Sacramento Regional Transit system got a surprise over the weekend when the agency's website displayed a message: “I’m sorry to modify the home page, i’m good hacker, i I just want to help you fix these vulnerability," it read in part. But as the Sacramento Bee explains, the hacker wasn't so kind-hearted after all. The message turned out to be a trap, and when technicians dug in to investigate, they inadvertently unleashed an attack that began erasing data and programs. The hackers then sent a Facebook message demanding one bitcoin in ransom to halt the attack. That demand is relatively low as these things go, notes a post at CoinTelegraph, although the cryptocurrency was trading at about $8,100 per coin on Tuesday. The transit agency opted not to pay and instead temporarily shut down its computer systems, including the one for processing credit card payments. The extent of the damage was unclear Tuesday, but CBS Sacramento reports that 30 million files of some kind were deleted. The agency says no personal information was stolen. The website was back online as of Tuesday afternoon and fully operational, per a Facebook post by the agency, which says its defenses were being shored up to prevent a similar hack in the future. It also notified the Department of Homeland Security, notes Techwire.
