Recently, Adobe released security update for Flash Media Server and Flash Player. The first update resolves critical vulnerabilities, which affect Flash Media Server (FMS) 4.0.1 and prior versions, and FMS 3.5.5 and prior versions for Windows and Linux. The vendor has recommended users to install FMS 4.0.2 and FMS 3.5.6 to prevent exploitation of critical vulnerabilities. The latest update mitigates memory corruption and data corruption issues. The memory corruption issue could allow attackers to execute arbitrary code, whereas data corruption issue could cause denial of service vulnerability.
The second update resolves critical vulnerabilities in Adobe Flash Player, which affect 10.2.159.1 and prior versions for Windows, Macintosh, Linux and Solaris users, Flash Player 10.2.154.28 and prior for Chrome users, and 10.2.157.51 for Linux users. Windows, Macintosh, Linux and Solaris users must upgrade to 10.3.181.14, Chrome users to version 11.0.696.68 of Chrome and Android users to 10.3.185.21. The latest Flash Player mitigates design flow, integer overflow issue, several memory corruption and bounds checking vulnerabilities. The flaws may crash the application and allow attackers to gain control of the compromised computers. The vendor has alerted users of attempts by attackers to exploit the vulnerabilities through malicious .swf file embedded in Microsoft Word and Microsoft Excel. The malicious documents are sent as attachments with cleverly crafted e-mails. Unscrupulous users, who fall prey to the enticing e-mails and open attachments, inadvertently install malware in their computers. The malware could be used to extract, delete or modify information stored in computers. Attackers may use the stolen information to launch phishing attacks, dispatch spam e-mails and extract more sensitive information from Internet users.
Adobe products are popular targets of cybercriminals as they are widely used by Internet users. Attackers may also target employees to compromise an organization’s computers and gain access to privileged business information. Hiring professionals qualified in IT degree programs may aid organizations in timely identification and application of necessary security updates to software applications.Online IT courses may help IT professionals to update themselves on latest developments in the field of IT security.
Employees must be trained on safe computing practices through e-learning programs, and encouraged to undertake online IT degree programs to create IT security conscious culture in organizations. Internet users must avoid opening attachments from strangers and unknown sources. Installing latest updates to software applications, and anti-malware solutions may help users in safeguarding their computers from malicious attacks.

Recently, the website of Pravda (The Truth), a major Russian newspaper suffered security breach. Cybercriminals allegedly inserted malicious scripts on the site. The malicious scripts are designed to compromise vulnerable computer systems. Security researchers at F-Secure have detected that the webpage surreptitiously load malicious scripts to exploit Java vulnerabilities and installs malware in a user’s computer. Usually, cybercriminals alter the home page of the site, leave a message or insert pictures. However, in case of stealth attacks such as the one on Pravda website, the attackers make silent alterations on the site to remain undetected to infect computer systems of large number of visitors. Websites continue to be the favorite target of cybercriminals. Attackers attempt to take advantage of the traffic generated by the websites. Recently, some webpages of NASA, Stanford University and some other American Universities were reportedly rigged by cybercriminals to sell fake software. Attackers allegedly used search engine poisoning to exploit the traffic generated to NASA website before the upcoming launch of the Space Shuttle Endeavor.
Attackers may gain remote access to the compromised computers by executing malicious code. They may modify, delete or extract sensitive data from the affected systems. Attackers may also use compromised computers to launch spam campaigns. They may also use the systems to launch simultaneous attacks on a target web resource. Internet users must avoid visiting reported forged sites, adhere to the warnings from the vendors and Internet security firms. They must install and regularly update security software to safeguard their systems. They may also adjust the browser settings to avoid automatic execution of malicious scripts. Internet users must use genuine software applications and constantly update their browsers.
Attackers constantly scan websites to exploit vulnerabilities. Cybercriminals may not only target Internet users, but also attempt to gain unauthorized access to the databases associated with the webpages. The extract information could be misused for fraudulent purposes. For instance, attackers target University websites to steal personally identifiable information related to students, faculty members and employees such as names, mailing addresses, e-mail address, contact numbers, course details, enrolment numbers, provident fund details and social security numbers. The stolen information could be misused for applying fake student loans, claim fraudulent tax refunds, redirect mail, identity theft and other fraudulent activities. Websites are susceptible to SQL injection, Cross-site scripting and other forms of attacks. Regular in-depth evaluation through professionals qualified in IT masters degree and penetration testing may help organizations in weeding out security flaws. Organizations may also benefit from the services of Internet security firms to understand weaknesses and initiate mitigating measures. Hiring employees qualified in online computer degree programs may help in safe online computing practices and adherence to security policies of the organization.
Internet security professionals must constantly upgrade their skills to deal with the vibrant challenges in the cyberspace. Online technology degree programs may help professionals in understanding latest threats and security mechanisms. Proactive approach is crucial to strengthen the defenses of the IT infrastructure and improve the IT security environment.
