Ransomware Attacks Disrupt School Reopenings

Published

on

A flurry of recent attacks is complicating attempts to deliver classes online at some schools in different parts of the country.

School reopenings — already bogged down by concerns over the COVID-19 pandemic — are being further complicated by targeted ransomware and denial-of-service attacks.

This week, Hartford Public Schools (HPS) in Connecticut became the latest to announce a ransomware attack that in its case forced school reopening to be delayed by one day. School officials said multiple critical systems had been knocked offline by the attack, including one used to communicate transportation routes to the district’s bus company. That prevented the district’s ability to operate schools on Tuesday as scheduled, HPS said.

Multiple other school districts have reported similar incidents in recent days. On Tuesday, the Clark County School District in Las Vegas said some of its systems had been infected with ransomware on Aug. 27. The incident impacted systems containing current and former employee data, according to the school district.

Last month, Hayward County Schools in North Carolina was forced to discontinue online classes for students for several days — including opening day — following a ransomware attack. More than a week after the intrusion, many services remained unavailable, and school officials warned that restoration work could take several weeks. They later announced the attack had also resulted in sensitive data potentially belonging to employees and students being compromised in the incident. Similarly, school reopening at Oklahoma’s Ponca City School system was delayed by a week last month after a ransomware attack crippled the district’s ability to deliver online classes.

The flurry of ransomware attacks — like almost every other cyber threat over the past several months — is being driven by the hasty switch to remote learning triggered by the COVID-19 pandemic. School systems, which even before the pandemic had to contend with tight IT budgets, have just not had the time or resources to implement defenses for countering new cyber threats tied to the pandemic, security experts say.

“[The pandemic] has forced the use of many technologies the schools have never used before. Most of the services and systems making remote learning are completely brand new to them,” says Curtis Preston, chief technical evangelist at Druva. “So the already existent problems presented by underfunding and the ability to only deliver basic IT services have increased by an order of magnitude in light of the pandemic.”

Scott Gordon, chief marketing officer at Pulse Secure, likens the heightened threat that schools face to the increased threat that most organizations in general have experienced in the past several months. He points to a recent study conducted by Pulse that showed 80% of organizations have experienced greater malware issues with the recent expansion of remote computing.

“The move to a digital classroom mimics the increase in threats that other industries are coping [with] as they enable a hybrid and flexible workplace,” Gordon says.

According to Gordon, while many schools have defenses aligned to monitor, protect, and prepare for recovery of their critical assets, others don’t because of budget and resource considerations. As a result, “remote access exposures have grown due to vulnerable endpoints, phishing, and at-risk connectivity,” he notes.

The surge in attacks on schools is not entirely unexpected. A study that Armor conducted back in April showed at least 284 entities across 17 school districts and colleges were hit in ransomware attacks between Jan. 1 and April 8 alone. At the time, the security vendor had predicted an increase in such attacks in the following months. A previous Armor study found over 1,000 schools were hit in ransomware attacks last year.

Druva’s Preston says the attacks heighten the need for better data backup practices at schools.

“The one thing they all must do is to back up anything they are doing to a system that separates backups from any attacks,” he says.

The DDoS Threat
Ransomware is not the only concern that schools face as they prepare for an academic year where most courses will be delivered online. Distributed denial-of-service (DDoS) attacks are another major concern. According to security vendor Kaspersky, DDoS attacks targeting schools and other educational institutions surged between 350% and 500% each month between February and June 2020 compared with the same period last year.

“For the last half a year, we have seen the number of attacks on educational and government resources grow faster than on other kind of resources,” says Alexander Gutnikov, a DDoS expert at Kaspersky.

So far, at least most of the attacks on these organizations have been politically motivated or plain acts of hooliganism, he says. But that could soon change as well.

Late last month, the FBI warned about criminals claiming to belong to the Russia-based Fancy Bear cyber espionage group conducting ransom DoS attacks on financial institutions and organizations in other sectors. In many of the attacks — which started last month — the threat actors have asked targeted organizations to pay a demanded ransom amount within one week or face the prospect of a major DoS attack. Most of those targeted in these attacks did not report any additional activity after the deadline passed, or they successfully mitigated the threat, the FBI said.

There is some concern that similar attacks could be directed at school systems, which are far less prepared to deal with DoS attacks than financial organizations.

Barrett Lyon, CEO of security vendor Netography, says the rushed move to remote learning and the comparative lack of preparedness among schools to deal with related cyber threats has left many vulnerable to cyberattack. 

“Schools are sitting ducks” for cybercriminals, he says. Because any attack that disrupts a school’s ability to deliver classes online would be chaotic in present circumstances, criminals know it is easy to shake them down, Barrett says.

Significantly, it’s not just criminals who schools need to contend with. Almost anyone — including students — who wants to disrupt online course delivery are a threat, he says.

One example is a 16-year-old student in Florida who launched eight DDoS attacks on networks belonging to the Miami-Dade Public Schools system. The August attacks were designed to overwhelm the school district network and disrupt its ability to deliver classes online. Florida law-enforcement authorities arrested the student earlier this month and charged him with a third-degree felony count and a second-degree misdemeanor charge.

Barrett says he expects such attacks will continue.

“A lot of schools are not equipped to deal even with basic DDoS attacks,” he says.

Bitdefender Ransomware Vaccine

Published

on

The “Bitdefender ransomware vaccine” can be seen here.

To address the escalating ransomware menace, Bitdefender is distributing a ‘vaccine.’

Bitdefender, a Romanian security software provider, has released a free replacement programme to prevent your machine from being infected by ransomware.

Table of Contents

Bitdefender Ransomware Vaccine

The Bitdefender Antiransomware vaccine protects your system from crypto-ransomware such as CTB-Locker, Locky, and TeslaCrypt by making it appear as though it has already been infected with malware.

Various ransomware strains, such as variants of Locky and TeslaCrypt, frequently employ a mechanism that detects if a computer has already been infected with the malware and had its files encrypted. Bitdefender’s new software, on the other hand, claims to be able to mimic these checks, meaning that if your computer is ever infected with ransomware, the virus will bypass it.

“In some ways, the new technology is an offshoot of the Cryptowall vaccine programme,” said Catalin Cosoi, Bitdefender’s senior security strategist. “We had been looking for a solution to prevent this ransomware from encrypting files even on PCs that were not covered by Bitdefender antivirus, and we recognised we could expand the thought.”

Dell informed customers that updates released patch to fix critical vulnerabilities

The original Cryptowall vaccine tool functioned similarly, but it may soon become obsolete and in need of an upgrade to keep up with how ransomware evolves and becomes more complex.

Bitdefender’s latest tool covers many more ransomware variants than before, but it’s not an all-in-one solution or blatant prevention tool.

Ransomware has recently taken on new forms, including a strain that targets WordPress sites rather than computers. As a result, this new anti-ransomware vaccine should not be viewed as a long-term solution, as more sophisticated threats may arise sooner rather than later.

Bitdefender isn’t the only company working on a ransomware vaccination. Sean Williams, a developer, is working on a tool called Cryptostalker to prevent ransomware from infecting Linux systems, while researcher Sylvain Sarméjeanne is working on a Locky-fighting tool.

Windows Firewall Allow Ping

Published

on

Table of Contents

Using Group Policy, enable ICMP (PING) over the Windows Firewall with Advanced Security

Prerequisites

On Windows 7, Windows 8, Windows Server 2008, Windows, or Server 2012, you’ll need the Group Policy Management Tools. These are part of the Remote Server Administration Tools (RSAT), which may be downloaded from Microsoft’s website.

Instructions

Please follow these instructions to activate ICMP on devices using Windows Firewall with Advanced Security (Windows Vista, Windows 7, Windows 8, Windows Server 2008, Windows Server 2012).

  1. Using the Group Policy Management Tool, you can edit an existing Group Policy object or create a new one.
  2. Expand the node pc Configuration/Policies/Windows Settings/Security Settings/Windows Firewall with Advanced Security/Windows Firewall with Advanced Security/Inbound Rules in the pc Configuration/Policies/Windows Settings/Security Settings/Windows Firewall with Advanced Security/Windows Firewall with Advanced Security/Windows Firewall with Advanced Security/Windows Firewall with Advanced Security/
  3. Click Next after selecting the Custom radio button.
  4. Select the radio box for All Programs and then click Next.
  5. Select ICMPv4 from the Protocol Type: sink list and click Customize…
  6. Check the radio selection for All ICMP types and then click OK.
  7. Note: If you want to limit ICMP to specific types, you need allow at least Echo Request.
  8. You can either limit which IP addresses ICMP can and cannot communicate with, or tick the Any IP address radio buttons to allow all, then click Next.
  9. Click Next after checking the Allow Connection radio option.
  10. Select which profiles will be affected by the rule. At the very least, tick the Domain profile checkbox and then click Next.
  11. Remove the Name: field from the rule and give it a relevant name. If desired, create an outline and then click Finish to depart and save the new law.
  12. Using the Group Policy Management Tool, verify that the Group Policy Object is applied to the appropriate computers.
    Allow pings over the Windows firewall.

Overview

Ping requests are prohibited by default if you have the Windows Firewall Allow Ping option activated. The University Information Security Office’s (ISO) vulnerability scanners are unable to work as a result of this. Follow the procedures below to configure your firewall to allow pings.

To complete these tasks, you may be asked for administrator access.

Firewall in Windows

  1. Open Windows Firewall by searching for it and clicking on it.
  2. On the left, select Advanced Settings.
  3. Click Inbound Rules in the left pane of the resultant window.
  4. File and Printer Sharing (Echo Request – ICMPv4-In) is one of the fundamentals.
  5. Enable each rule by right-clicking it and selecting Enable Rule.

Firewalls from third parties

See Vulnerability Scanners if you use a third-party firewall application or appliance.

It’s difficult to hide all conceivable ways of enabling ping on all possible firewalls because each third-party firewall is set differently.

However, to fill out the form to configure your firewall, you’ll need the following information:

  • Many firewalls allow you to whitelist specific IP addresses or ranges. Vulnerability Scanners has the IP ranges for UISO scanners.
  • Some firewalls allow specified protocols or services to pass through. You should enable ping in certain instances. The setting is known as “ping” or “incoming ping” on some firewalls. Others inquire about it using the technical term “ICMP Echo Reply.” Allow this protocol in either case.
  • Many firewalls also include options for allowing specific ports to communicate (do not confuse networking TCP ports with the physical serial, parallel, USB, or Ethernet ports). Don’t worry about those settings for the UISO scanner; only “ping” (ICMP Echo Reply), which doesn’t require ports, has to be enabled. With other reasons, you’ll want to allow or disallow specific ports, but it’s pointless to try to do so for the UISO scanner.
