The Cisco – a global IT leader that provides cyber intelligence and advanced threat protection portfolio to the organisations – has released their 2017 Annual Cybersecurity Report, that presents research on the most commonly observed malware.
Malware, which a short term for malicious software, is a program that can infiltrate and damage your PC, access sensitive information or disrupt your mobile operations. The general terms for such threats are virus, spyware, adware, ransomware, worms, trojans, toolkit and so on.
As the digital world is expanding, it also expands the surface of such malicious attacks. The strategies of attackers include:
● Taking advantage of lapses in patching and updating
● Luring users into socially engineered traps
● Injecting malware into supposedly legitimate online content such as advertising
According to the Security professionals, Mobile devices, Public cloud, Cloud infrastructure and User behavior are the biggest risk of exposure to a cyber attack.
Most Commonly Observed Malwares
In their report, Cisco has revealed the most commonly observed malwares. Below are the top ten of such malicious attacks.
1. Reconnaissance – an initial step for launching a cyber-attack. In this phase, attackers look for vulnerable spots in internet infrastructure or network weaknesses that will allow them to gain access to users’ computers and, ultimately, to infiltrate organizations.
2. Suspicious Windows Binaries and potentially unwanted applications (PUAs). Suspicious Windows binaries deliver threats such as spyware and adware. Malicious browser extensions are an example of PUAs.
3. Facebook Scams – include fake offers and media content along with survey scams. Facebook has nearly 1.8 billion monthly active users worldwide which makes it a logical territory for cyber criminals.
4. Trojan Downloader – made it to 4th on the list. It is one of the most used way of attacking user’s data. It is installed through opening links in spam emails or an image download which affects victim’s computer.
5. Browser Redirection Malware – The 5th most commonly observed malware of 2016. Browser infections can expose users to malicious advertising (malvertising), which attackers use to set up ransomware and other malware campaigns.
6. Browser Redirection-Downloads – This is also one of the mostly commonly found malware. Internet users counter this every day, and if they aren’t aware they mistakingly click on it and it not only redirect the browser but also download the malicious malware to the computers.
7. Phishing Links are a way of deceiving users by redirecting them to a spoofed website that looks legitimate.
8. Android Trojans – These have been moving steadily up the short tail list over the past 2 years. Loki malware is the example of that. It encrypts users files and then demands ransom in order to give you the key to get them back.
9. Facebook Hijacking – This is also one of the most used way of hacking users data. The malware posses as Chrome extension or Firefox add-on threatens users security.
10. Heuristic Blocks – This Trojan can enter your PC in many ways and harms your data, corrupts your files and even delete them. It also reduces CPU performance.
Users shall be careful and always have an antivirus in their mobiles and personal computers. This way attackers will find it extremely difficult to gain access to valuable information.
