4 Most Common Types of Cybersecurity Threats
Advanced phishing attacksPhishing takes place when a hacker tricks an individual into handing over information or exposing sensitive data using a link (with hidden malware) or a false email. These types of security threats are quite common, but in recent months they are becoming even more advanced. Microsoft’s recent survey of business leaders in four countries found that phishing threats are currently the biggest risk to security. Since March, 90% of those polled said that phishing attacks have impacted their organization, and 28% admitted that attackers had successfully phished their users. Recently, phishing emails have targeted enterprises to capture personal data and financial information using one of the following tactics:
- Posing as a provider of information about COVID-19 vaccines, PPE, and other health and sanitation supplies
- Creating false “portals” for business owners to apply for government assistance and stimulus funds during the economic shutdown
- Using download links for platforms and tools that help remote teams communicate, such as video conferencing
- Posing as “critical update” downloads for enterprise collaboration solutions, such as Microsoft OneDrive, and social media applications
- Targeting IT service providers that ask for payment in order to provide tech support.
RansomwareRansomware is a type of security threat that encrypts a victim’s files so they can’t access their information. The hacker then asks for a ransom – usually payment – to restore access and decrypt the user’s data. Perhaps the most notorious recent example of a ransomware attack is that of Garmin. In July, Garmin – a navigation and fitness wearables company – was hit by a ransomware attack that downed service for virtually every Garmin customer. “Hackers deployed the ransomware tool WastedLocker, which encrypts key data on a company’s digital infrastructure,” reported Cyber Security Hub. “In the case of Garmin, website functions, customer support, and user applications were all affected. Unlike typical ransomware software, WastedLocker does not steal identifying information and hold it for ransom. Instead, it renders programs useless until decrypted.” Garmin reportedly paid $10 million for the decryption key to resume services after four days of outages. Garmin isn’t alone, however. There’s been a seven-fold increase in ransomware attacks this year targeting companies of all sizes. So, what can your organization do to protect itself? How to prevent ransomware: First and foremost, it’s important to make sure your security protocols are kept airtight – and apply security patches as quickly as possible to prevent hackers from exploiting vulnerabilities. A tool like Nightfall can make it easier to maintain a strong defense, with AI monitoring your network for any issues. Multi-factor authentication can also prevent hackers from getting too far into your system. And, you should regularly back up your system so if a ransomware attack does happen, you’ll be able to recover some data.
Password-based cyberattacksA password-based cyberattack is one that targets users who have the same password for multiple sites. Research from the World Economic Forum found that 4 out of 5 global data breaches are caused by weak/stolen passwords. There are several different ways a hacker can infiltrate your system using a password-based cyberattack. The most common method is known as a brute force attack. This attack uses a computer program to try to login to a user’s account by trying all possible password combinations, starting with the most common and easiest to guess options – for instance, “1234” or “abcde”. Sensitive data like passwords, credentials and secrets are in constant danger of exposure, especially as more companies conduct the majority of their business in the cloud. The highly collaborative and always-on nature of cloud services make it hard to enforce good password practices. Therefore, organizations need data loss prevention (DLP) to secure essential data from being exposed. How to prevent a password-based attack: make it easy for users and security teams alike to circumvent the risk of password attacks by implementing password-free authentication methods. This is a type of authentication that requires a user to confirm their identity during the login process through a separate channel. This extra step can also protect your workspace in case there’s any account compromised or if a device gets stolen.
IoT and smart medical devicesThe internet of things makes life a lot easier – and also more open to bad actors. Connected devices are an increasingly popular target for cyber threats. In 2019, cyberattacks on IoT devices increased by 300%, according to one report. This includes attacks on everything from laptops and webcams to smart homes (like Google Nest), smart watches, routers, and other home appliances. Our personal devices aren’t the only things that are vulnerable. The Software Engineering Institute of Carnegie Mellon University reported, “As more devices are connected to hospital and clinic networks, patient data and information will be increasingly vulnerable. Even more concerning is the risk of remote compromise of a device directly connected to a patient. An attacker could theoretically increase or decrease dosages, send electrical signals to a patient or disable vital sign monitoring.” Healthcare providers must also contend with protecting patient data. As many healthcare providers shift to remote work, they become an attractive target for hackers. Protected health information (PHI) must be kept safe during all cloud-based activities – yet many SaaS providers, including Slack, are not HIPAA-compliant right out of the box. How to prevent IoT attacks: IoT attacks are sophisticated, and the best ways to protect your devices are to use strong passwords and keep your software up to date. Experts also suggest keeping your devices unlinked from social media. Along with protecting your devices, look for a DLP partner who can protect your patient data while working on SaaS and IaaS platforms. Check out our coverage of instituting and maintaining HIPAA compliance on Slack and schedule a meeting below to learn more about how tools like Nightfall DLP play a role in keeping PHI safe.
