Five Types of Cyberattacks You Need to Know
The threat of cyberattacks on organizations is greater than ever before. Organizations are rapidly adopting cloud services, work from home policies, and IoT, leaving their data in disparate locations, in different workloads, and at the hands of more users than ever before. In this threat landscape, it means they are leaving themselves exposed to vulnerabilities they don’t even know exist.
While cyberattacks have been around for years, they are now evolving at a faster pace, and new types of attacks are entering the scene every day. I’ll describe five types of cyberattacks that you might not be aware of, but you certainly should be.
Credential reuse attack
This is not a new threat. Simply put, credential reuse or ‘stuffing’ is when a cybercriminal gains access to valid credentials and uses them to gain access and compromise other accounts and systems. Although this is not a novel idea, organizations, and their users (even critical employees), continue to re-use credentials and place themselves and their organization at risk.
As long as there are individuals in organizations, there will always be a risk of an insider threat. This may come in the form of a current or former employee, contractor, or even a partner. There are several types of insider threats:
- Employees stealing information for personal use
- Theft of intellectual property or credentials that are sold to a foreign government or organization
- A disgruntled employee sabotaging data, network, or production systems
As the 2022 Cost of Insider Threats: Global Report reveals, insider threat incidents have risen 44% over the past two years, with costs per incident up more than a third to $15.38 million.
Phishing attacks are social engineering attacks designed to steal data, credentials, and/or gain access to a system. These attacks are usually coupled with other attacks like ransomware. In the past, these spoofed emails, messages, or even calls were easy to identify. Cybercriminals have become much more skilled at sending emails with valid design and verbiage to appear legitimate for any institution.
Man-in-the-middle attack (MiTM)
TechTarget defines a MiTM attack as “a type of cyberattack in which the attacker secretly intercepts and relays messages between two parties who believe they are communicating directly with each other. The attack is a type of eavesdropping in which the attacker intercepts and then controls the entire conversation.”
Although there are other types of attacks like Denial-of-service (DDoS) and SQL injections that happen at a higher rate, we believe double-extortion ransomware attacks are especially terrifying.
Double-extortion ransomware functions the same way as a traditional ransomware cyber-attack, the only difference is that instead of simply encrypting data and demanding a ransom, attackers will threaten to leak or delete critical data. This situation can be devastating to an organization, financially and in terms of reputation and consumer trust.
Cybersecurity is one of the few industries where innovation is on the side of a criminal. Hackers will find exploits, open opportunities, and even zero-day vulnerabilities. Once exposed, cybersecurity professionals and vendors work hard to address these threats, but novel attacks will continue, and the threat will grow.
