Mike SmithLicking County, a county east of Columbus, Ohio, recently experienced a bad ransomware attack on its IT systems. Ransomware is a specialized virus that encrypts files—making them nearly impossible to access unless you pay criminals a ransom. Cybercriminals use ransomware to extort money in return for unlocking your files. Many organizations pay the ransom despite the FBI and other law enforcement agencies recommending against it.

Luckily, Licking County managed to mostly survive the attack based on implementing some important best practices. Let’s look at the good, bad, and ugly of this situation to extract some important lessons.

The Good

Data backups

The difference between getting crippled and devastated by a ransomware attack versus surviving it relatively unscathed all comes down to data backups. Licking County ended up losing only about one day’s worth of data for most systems. Another county referenced in the article ended up paying a ransom of $2,500 to cybercriminals because they did not invest in data backup.

Activating a plan to shut down the network

To stop the spread of the ransomware, Licking County shut down its network. Clearly, the county had a plan in place and enacted it when the ransomware virus hit. By planning ahead, they were best prepared for what to do to keep the virus contained and to minimize impact.

Rebuilding systems based on highest priority data

As part of its disaster recovery plan, the county rebuilt its systems based on the highest priority data first. The article references data such as “servers that house felony-case tracking for the prosecutor's office and the auditor's property-records database.” Any disaster recovery plan needs to have a clear plan as to how data will be restored—and in what order of priority.

The Bad

Rebuilding systems will take a lot of time

Licking County is a big county and so it needs to reformat about 1,000 computers as part of its rebuild. That takes a lot of time. Even smaller organizations will need to spend significant time rebuilding servers and reformatting computers.

Direct and indirect costs

Directly, the costs of billable IT time and possibly enhancing networking equipment and cyber protection software can present a big hit to your budget. Indirectly, lost productivity wastes expensive employee salaries and potentially delays major projects when time is ticking.

Impacts to citizen service

After a disaster, a crippled government entity will not be able to serve citizens at full capacity. The mission of government gets impacted when ransomware hits. County Commissioner Tim Bubb says, “We have lost a large part of our focus on serving the people of Licking County. What price do you put on that?"

Potentially weak firewall and network connections

A Columbus Dispatch article mentions that the county needs to shore up its “firewall and network connections.” An improperly configured firewall can leave ports open that allow hackers to easily gain access to servers and steal information. Setup of switches, routers, and other networking equipment also impacts security.

Potentially weak passwords

The same article mentions that the county needs to encourage employees to change passwords more frequently. In a recent blog post, we said, “The longer a password is in use, the more likely that hackers will be able to crack it. The more you change passwords, the more difficult you make a hacker’s job.”

The Ugly

911 dispatching affected

An article published in the Newark Advocate the day after the incident stated “...the 911 Center has been operating in manual mode since late Tuesday night. The 911 Center phones and radios work, but dispatchers do not have access to their computers. The public can still call 911 for emergency police, fire or medical response.”

While not completely shut down, any impact to 911 or other critical emergency services can literally affect lives in the wake of a ransomware attack.

Employees click on too many suspicious emails

One of the biggest cybersecurity threats is people. No matter how great your data backups, antivirus, firewalls, and security measures, hackers and cybercriminals still often break into a government entity through people clicking on suspicious websites and email attachments.

Note this paragraph in the Columbus Dispatch story:

Fairfield County started working last year to tighten procedures to guard against the type of cyberattack that occurred in Licking County, said Fairfield County IT Administrator Randy Carter. He said he was dismayed when he sent a test phishing email to county employees in September and more than 25 percent clicked on it. Carter plans to provide training to employees on what emails to avoid.

25 percent! One in four people got fooled by these dangerous emails. Each click on one of these emails opens you up to the threat of a virus or ransomware.

Cybercriminals targeting government more and more

Cyberattacks grow more numerous and targeted. Government entities are ripe for these attacks. That includes cities.

Are you prepared?

  • Like Licking County, do you have data backups to recover from a ransomware attack?
  • Do you have the right network equipment and modernized technology to protect yourself?
  • Are your employees trained about the dangers of clicking on malicious emails and websites?
