Hackers begin targeting VPNs as the world moves remote

Hackers begin targeting VPNs as the world moves remote

A few weeks ago, VPN use was limited, compared to today. Tens of thousands of businesses have moved exclusively to VPNs in the past week posing a unique security vulnerability and opportunity for hackers.

In an alert issued March 13, the Cybersecurity and Infrastructure Security Agency (CISA), a department of Homeland Security, encouraged organizations to adopt a heightened state of cybersecurity during this period.

Security Issues of VPNs

As organizations use VPNs for telework, more vulnerabilities are being found and targeted by malicious cyber actors. Virtual Private Networks or VPNs are a virtual “tunnel” that encrypts your data as it is sent from one point to another. Because VPNs act like a tunnel if one end is not secure (your home network), the other side (your business network) isn’t either. This presents potential vulnerabilities to networks that need to remain secure.

Maintain Your VPN Updates and Patches

Additionally, if VPNs are being used 24/7, organizations without managed services or dedicated IT personnel are less likely to keep them updated with the latest security updates and patches. Patches update known security vulnerabilities to maintain security. The longer your VPN goes without updates, the greater the risk for a breach.

Look Out for Phishing

Malicious cyber actors may increase phishing emails targeting teleworkers to steal their usernames and passwords. With log-in credentials, hackers are able to deploy the malware of their choosing or steal vital information.

The report also stated that organizations that do not use multi-factor authentication (MFA) for remote access are more susceptible to phishing attacks.

VPN Limitations

Organizations may have a limited number of VPN connections, after which point no other employee can telework. With decreased availability, critical business operations may suffer, including IT security personnel’s ability to perform cybersecurity tasks.

Alternative Options

If your staff has a desktop computer in the office, but they are at home and only have access to their personal computers and the internet, we recommend using ScreenConnect.

ScreenConnect provides secure remote access for your staff to work on their office computer, from any computer with an internet connection. Your staff can maintain the same desktop experience as if they were in the office, including line of business applications, filesharing, and most importantly security.

ITonDemand can add this service on a per-user/computer basis for only $5/mo. This service can easily be removed once life returns back to normal.

LookBack Malware Targets Utilities Companies

LookBack Malware Targets Utilities Companies

LookBack looks to shutdown US Utilities

The U.S. utilities sector is starting to see higher levels of spearphishing attacks using “LookBack” malware. 

According to a security researcher, spear phishing email campaigns have been identified containing the malware initially targeting three major US utilities companies. The fraudulent emails impersonate a U.S.-based engineering licensing board, with emails originating from a threat actor-controlled domain.

The emails contain Microsoft Word attachments that use macros to install and run the LookBack malware. The malware specifically contains a remote access Trojan (RAT) module and a proxy mechanism used for command and control (C&C) communication. As soon as the attachment was opened, LookBack was initiated.

What to watch for:

Any email that contains attachments should receive hyper-vigilance and speculation. If you employ advanced email security, emails are scanned for malicious content and attachments but you shouldn’t leave that to chance. 

July’s LookBack attacks on U.S. utilities have not been associated with a known actor, and no infrastructure or code overlaps were identified.

Phishing Emails Disguised as Office365 File Deletion Emails

Phishing Emails Disguised as Office365 File Deletion Emails

Threat Level: High

A recently-discovered phishing scam pretending to be from the “Office 365 Team” is trying to trick users into their log-in credentials.

The alert notifies the user of an unusual volume of file deletions and urges users to review the activity.

When redirected, the users are encouraged to log-in to a page that is hosted on Azure, increasing the perceived legitimacy of the phishing campaign. The hackers have even gone as far as securing the page with a certificate signed by Microsoft.

It’s important to remember that Microsoft login forms will be coming from microsoft.com, live.com, microsoftonline.com, and outlook.com domains only.

If you think you may have been deceived by a phishing scam, it’s important to contact ITonDemand urgently to begin Incident Response.

Ransomware hit a Michigan Doctor’s Office, The Results were Catastrophic

Ransomware hit a Michigan Doctor’s Office, The Results were Catastrophic

In recent months, hackers have begun targeting doctors offices and hospitals, receiving roughly 34% of all ransomware attacks. In an unprecedented incident, it just cost two doctors their practice.

What happened

Last month, the offices of Brookside ENT in Battle Creek, Michigan, experienced a ransomware attack. The hackers encrypted patient information and demanded a ransom in exchange for a password to decode the information. 

Drs William Scalf and John Bizon decided not to pay the ransom.

The hackers then proceeded to delete all medical records for the patients. The doctors had no record of anything from appointments to surgery results.

Some who had just undergone surgery are having difficulty receiving follow up care because there is simply no record of their surgery.

And because there is no patient schedule the doctors have to wait at their practice for someone to show up. There isn’t even a way to call and inform their patients as there are no phone numbers on record.

Rather than try to rebuild their practice from scratch, Brookside ENT will permanently shut their doors on April 30th, 2019.

It could have been worse.

If the hackers would have been able to view the information, not only would that have resulted in a HIPAA violation on the part of the doctors but it also would have compromised the identity security of all the affected patients.

What other practices can learn

Protect Your Email

91% of all malware originates in an email. Because each email account is a potential vulnerability, it’s important to employ a spam filter as well as provide training to your employees on identifying threats.

“…Education about the risks and preparedness are as important as IT security measures for protecting individuals and assets from cyber attacks,” said Katherine Keefe, Beazley Breach Response Services Head in response to the Brookside Ransomware attack.

Use Endpoint Malware Security

In the event of a ransomware attack, endpoint malware security can block lateral movement. This isolates the attack to a single device rather than encrypting every device on a network.

Endpoint security can also block the ransomware’s download of encryption keys.

Small Business, Big Target

Repeatedly, hackers are targeting small business because they are viewed as easy targets.

61% of all cyber attacks target small business.

This doesn’t have to be the case for your business. ITonDemand offers affordable and scalable IT solutions to partner in the prevention of these types of attacks.

Beware of TrickBot

Beware of TrickBot

Malware attacks are on the rise, but thankfully, so is the vigilance of individuals and IT MSPs.  

However the next big threat is on the horizon. On March 14th, the Cybersecurity and Infrastructure Security Agency, a unit of the Department of Homeland Security, released a report on malware called TrickBot.

What is TrickBot?

“TrickBot is a modular banking trojan that targets user financial information and acts as a dropper for other malware”, said the report. It is using man-in-the-browser attacks to steal the log-in credentials for finance-related sessions.

How it’s working

This malspam is embedding itself in email attachments in familiar formats like Word or Excel documents disguised as accounting reports or invoices. Once opened, the attachment will “prompt the user to enable macros, which executes a VBScript to run a PowerShell script to download the malware.”

It makes sure it is not running in a “sandbox environment” and then attempts to disable your antivirus programs.

Once it has established itself on a device, TrickBot will begin two different attacks.

Redirection attacks send victims to fraudulent banking site replicas when they navigate to certain banking websites. This fake website is hosted on the cyber threat actor’s (CTA) malicious server and harvests the victim’s login information.

A server-side injection intercepts the response from a bank’s server, injects additional client-side code into the webpage, and can steal the victim’s banking credentials through form grabbing. Form grabbing records sensitive information typed into HTML forms, rather than capturing all keystrokes as with a keylogger.

TrickBot is also using the Server Message Block Protocol to spread itself laterally across networks.

What you should do

Prevention
Familiarize yourself and your staff with common phishing tactics. Education is the ultimate end-user security practice. This is a necessity for network security.

For ITonDemand clients, spam filtering and endpoint malware security are in place to secure you from the majority of cyber attacks.

For more information on phishing, download our infographic below.

Incident Recovery

  1. If you think you have been infected, take the device offline as soon as possible. This protects you from any further data loss or further system/network corruption.
  2. Change all passwords from the infected device from a secure device.
  3. Contact the ITonDemand HelpDesk to see what further damage mitigation needs to be done.

Does this email smell phishy to you?

Does this email smell phishy to you?

How to identify if an email is a phishing attack

91% of all cyber attacks are delivered through an email. A company of 5,000 employees will receive an estimated 14,400 malicious emails per year.

It’s not abnormal to receive phishing emails. It’s only dangerous if you fall for the bait.  So how can you tell a phishing scam apart from a task that needs attention?

  • Look at the email address
  • Urgency
  • Hover, Don’t Click
  • Vague Pronouns
  • It’s Better to be Safe than Sorry

Look at the email address

This step usually begins by checking for spelling mistakes. They will usually appear as something related to the account they trying to gain access to. A few of my favorites are Oatlook, Paiypal, and Faceboook. Clearly, these aren’t correct but upon delivery in the context of your inbox, you tend to glaze over small pieces like that. Generally, they are small, subtle mistakes.

But even the from field can be manipulated; fairly easily might I add. Using open source software such as PHP Mailer, phishing attackers can manually type in both To and From addresses. When the email is delivered, the recipient will see an email that looks like it’s from the email account listed in the ‘From’ field, regardless of where it came from. It’s really that easy. That is how emails avoid spam filters and end up in your inbox.

Urgency

Phishing uses a false sense of urgency. This is intended to make users take action quickly without much thought to any inconsistencies in the email.

This can often look like “There was unusual activity detected on your account,” or “Your password is expiring today”.

The hope is that you are so concerned with losing access to an account that you make a decision (or mistake), that you wouldn’t normally.

PHISHING

Download our infographic and learn how to identify a phishing scam when you see one.

Hover, Don’t Click

You can examine the URL in question by hovering over a link rather than clicking directly. It will appear in your browser window in the bottom left corner. You can see in the photo to the right.

If it looks questionable, don’t click it and forward it to your security provider or response team.

Vague Pronouns

Mass Phishing Attacks will generally use vague pronouns such as “Valued Customer”. Even mass corporate communications will use your full/correct name.

In more direct, high-value attacks, known as spearphishing, hackers may do deep research to create a seemingly trustworthy email. In this instance, hyper-vigilance is necessary and a trustworthy IT partner to monitor breach detection and incident recovery.

Better Safe than Sorry

If you are worried about something, forward it to your IT team for threat detection. Worst case scenario, we send it back to you saying everything’s fine. If it is malicious, not only will we have secured this threat but also helped to identify any future threats.
