Watch out for these threats to Windows 7 security
As cyber crime is rising at an alarming rate, it is essential to be aware of the security threats to computer users. Windows is one of the most popular operating systems worldwide, so a majority of malicious programs are targeted at users of Windows-based computers. Although Windows 7 is an operating system with advanced security features and tools such as Windows Firewall, BitLocker Drive Encryption, and Microsoft Security Essentials, you need to be aware of new malware and take precautionary measures. Here are some threats to computers with Windows 7.
A “file-less” malware that executes without saving any file on a PC
Recently, security services and software company Kaspersky Lab has reported the discovery of a new malware that is unique in the sense that it is “file-less”. This malicious program runs in the memory without saving a file on a computer’s hard drive. The modus operandi of the malware follows a two stage process. First of all, it disables the Windows User Account Control (UAC) and secondly it sets up a bot. By setting up a bot, the malware communicates with a remote server to execute commands and also uses a Trojan to steal data from a PC.
Trojan.Dropper.UAJ can evade antivirus detection and it makes a copy of the comres.dll file in Windows. It then saves itself in the directory folder of Windows, which results in its execution when Windows searches a DLL required by an application. When the DLL is loaded, the Trojan also gets executed. The operating systems vulnerable to Trojan.Dropper.UAJ include Windows 7, Windows Vista, Windows 2003, Windows 2000, and Windows NT.
Remote Desktop Protocol (RDP) security flaw
Security loopholes were recently detected in Windows Remote Desktop Protocol (RDP). RDP is generally used by administrators to make connections with remote PCs. The flaw could be used by attackers to gain remote access to a computer having Windows operating system. The critical security bug was found in Windows 7, Windows XP Service Pack 3, Windows Vista, Windows Server 2008 R2, and Windows Server 2003. Microsoft has released security patches for these flaws, which can be installed through Windows update.
What can be done to tackle threats to Windows 7 security?
Windows 7 users can check the Action Center to ensure that the firewall and automatic updates are turned on. If you do not install Windows 7 updates that are released by Microsoft from time to time, your PC will become vulnerable to malware. It is recommended that users should regularly perform a complete antivirus scan of their Windows 7 PC. The antivirus should always be up-to-date with the latest virus definitions to avert new security threats. Use a browser with advanced security features that alerts you regarding malicious websites, phishing, and online security risks.
