[6] In 2020, with the increase of remote work as an effect of the COVID-19 global pandemic, cybersecurity statistics reveal a huge increase in hacked and breached data. [ 7 ]
This result was the first to show that computational complexity theory can be used to devise malware that is robust against reverse-engineering. A growing area of computer virus research is to mathematically model the infection behavior of worms using models such as Lotka–Volterra equations, which has been applied in the study of biological ...
Malware analysis is the study or process of determining the functionality, origin and potential impact of a given malware sample such as a virus, worm, trojan horse, rootkit, or backdoor. [1] Malware or malicious software is any computer software intended to harm the host operating system or to steal sensitive data from users, organizations or ...
On 17 December 2016, a year after the previous power grid attack, hackers again disrupted the Ukrainian power grid with a cyber attack. About one fifth of Kyiv lost power for an hour. While the outage was ultimately short, a report released 3 years after the attack by security firm Dragos outlines a theory that the malware, known as Industroyer ...
Malicious code is a broad category that encompasses a number of threats to cyber-security. In essence it is any “hardware, software, or firmware that is intentionally included or inserted in a system for a harmful purpose.” [6] Commonly referred to as malware it includes computer viruses, worms, Trojan horses, keyloggers, BOTs, Rootkits, and any software security exploits.
Unlike malware used by script kiddies to organize botnets, where the ownership, physical location, and normal role of the machines attacked is largely irrelevant, cyberweapons show high selectivity in either or both of their employment and their operation. Before the attack, cyberweapons usually identify the target using different methods. [3]
DURI - the DURI HEAT attack was discovered in 2020. Duri's payload was malware that had been previously detected. [9] However the delivery method evolved to use a HEAT attack technique, HTML smuggling, to increase its infection rate of targeted endpoints [10]:. Qakbot - Qakbot is a banking trojan that has been in use since at least 2007. Qakbot ...
Recently, the world has seen a rise in the number and severity of cyber attacks, data breaches, malware infections, and online fraud incidents. According to cyber security and ai company SonicWall, the number of ransomware attacks grew by 105% globally.
