Currently, the most feared form of malware is ransomware - a program designed to encrypt a victim's files and then demand a ransom in order to receive the decryption key 2021 saw an 82% increase from 2020 in ransomware-related attacks with some of the biggest attacks in history hitting critical Infrastructures and facilities. Here are some of the most common types of malware:

There are various types of malware, but they all use evasion and obfuscation techniques designed to not only fool users, but also evade security controls so they can install themselves on a system or device surreptitiously without permission. Malware, or malicious software, is an umbrella term used to refer to a hostile or intrusive program or file that is designed to exploit devices at the expense of the user and to the benefit of the attacker. So, which are the most damaging cyber attacks, and how do they work? Here are the 13 most damaging types of cyber attacks. Not only large organizations are at risk of cyber attacks cybercriminals will use any internet-connected device as a weapon, a target or both, and SMBs tend to deploy less sophisticated cybersecurity measures. This asymmetry highly favors any attacker, with the result that even large enterprises struggle to prevent cybercriminals from monetizing access to their networks - networks that typically must maintain open access and connectivity while trying to protect enterprise resources. These costs are both tangible and intangible, including not only direct loss of assets, revenue and productivity, but also loss of business confidence, trust and reputational damage.Ĭybercrime is built around the efficient exploitation of vulnerabilities, and security teams are always at a disadvantage because they must defend all possible entry points, while an attacker only needs to find and exploit one weakness or vulnerability. Cyber attacks are launched against organizations every day: According to Check Point Research, in the fourth quarter of 2021, there was an all-time peak in weekly cyber attacks, reaching over 900 attacks per organization, while IT Governance reported 34.9 million records breached in June 2022 alone.Ī RiskIQ study estimated that cybercrime costs organizations $1.79 million every minute.
