In this article, we will consider the top 5 cybersecurity threats you need to know in 2021. Read on to know more.
Cybersecurity 2021 and Beyond
Every day, experts discover more than 550,000 new malware samples. With this in mind, organizations should prioritize closing the security gaps.
Unfortunately, many of them are still at risk that enables hackers to access their systems.
Today, one of the most common exploits is zero-day attacks. These occur when the patches to security gaps are not yet available. Zero-day vulnerabilities are so common that attackers exploited 24 of them in 2020 alone.
Many software uses advanced memory manipulation techniques. As a result, they are tricky to identify if you count on basic security measures.
While dozens to thousands of new malware copies happen each day, a criminal can only employ a limited number of tactics.
One typical method involves a kind of random access memory (RAM) modification. But, there are measures you can take to defend yourself.
Modern, next-generation security solutions can safeguard your data and systems against the five most prevalent attack tactics listed below.
Popular Cybersecurity Risks in 2021
Return-oriented programming protection
Data execution restriction is a memory-protection mechanism at the system level. It is included with Windows os from Windows XP.
DEP enables the process to designate one or more memory pages as non-executable. Hackers would then be likely to dodge DEP.
They have been doing so efficiently for some time. They apply different approaches, such as return-oriented programming (ROP).
Memory manipulation
Criminals evade defenses such as DEP by using stack pivoting. This works by stacking ROP devices in return-oriented programming exploit.
Attacks can also pivot from the real stack to a new false stack via stack pivoting. It could also be a buffer accessible by the attacker, such as the heap.
Then, hackers will use the heap to influence the flow of program execution in the future.
Code injection protection
Process hollowing is a technique in which a legitimate program is put into the system in a delayed condition to function as containment for malicious code.
Because it creates a suspended hollow process, its memory is unmapped and overwritten with malicious code.
Reflective dynamic link library (DLL) loading also occurs when a DLL is imported from memory instead of from drive.
On the other hand, the Early Bird code injection technique utilizes the program threading method. It arises while a program is running on a device.
Then, it runs the malicious code early in the thread’s startup before many security controls put their traps. So, intrusion detection can’t identify the suspicious code.
Defense evasion protection
Criminals can use the assumption that only critical tasks are controlled to their advantage.
Triggers on critical API functions are common to modern cybersecurity systems. As a result, it can detect and conduct tests.
Yet, hackers could frequently bypass antivirus software. How?
They can enter through an unregulated, non-sensitive function. As a result, next-generation security technologies stop users from exploiting crucial neural networks. These systems are better capable of dealing with complex attacks.
