Hackers Dropping Malware via Free WinZip Trial Popup Vulnerability


Researchers have discovered a critical security flaw in WinZip 24 that targets users with malware. WinZip trial popup vulnerability allows hackers to perform arbitrary code execution and DNS poisoning.
When WinZip displays prompt informing about the expiry of the free trial and sends requests for checking updates, it communicates in plaintext over HTTP instead of HTTPS; the vulnerability has been reported to exist in the way WinZip communicated with its servers, making it susceptible to exploits by malicious actors who delivered malware through the same. 

WinZip is free to download ZIP tool program that is used to compress and decompress files easily. It enables users to zip and unzip almost all file formats including zip, tar, rar, and etc. However, the tool is available online free for a trial period, and to continue availing its services fully, users need to purchase a license for which the tool checks software status for users over a period of time, repeatedly. Once it detects the trial period being expired, the software displays a prompt using the abovementioned way of communication: That is where the bug was found.
It was in between that attackers could intercept the traffic and intervene in the communicated text and added an infected WinZip version. Furthermore, the users' concerns are aggravated by the fact that the update request also contains personal data of the user such as 'registered username', 'registration code', and other required information for the processing of the request. This information could also be accessed by the attacker meddling with the trial popup.
"WinZip 24 opens pop-up windows time to time when running in Trial mode. Since the content of these popups is HTML with JavaScript that is also retrieved via HTTP, it makes manipulation of that content easy for a network adjacent attacker," as told by Researchers from Trustwave.
"The application sends out potentially sensitive information like the registered username, registration code and some other information in query string as a part of the update request. Since this is over an unencrypted channel this information is fully visible to the attacker."
"This means anyone on the same network as user running a vulnerable version of WinZip can use techniques like DNS poisoning to trick the application to fetch “update” files from malicious web server instead of legitimate WinZip update host. As a result, unsuspecting user can launch arbitrary code as if it is a valid update," the researchers further added.

Romanian Google , Yahoo, Microsoft, Paypal, Kaspersky hacked By Algerian Hacker MCA-CRB

Google Romania hacked

Here is another DNS poison attack.  we can call this month as 'Month of DNS posion attack'. The report says hackers compromised the RoTLD - The Romanian Top Level Domain Registry and poisoned the DNS Records.

An Algerian Hacker group called MCA-CRB allegedly hijacked the domain registrar and change the DNS record such that it points to defacement page.

The list of affected Top Level Domains:

Hackers modified the DNS records such that it points to an IP address located in the Netherlands: ( .

The mirror of the defacement can be found here:

At the time of writing, the affected sites are back to online and working properly.

According to the Zone-H record, the hacker group MCA-DRB, has defaced 5,530 site websites so far, many of them appearing to cover government and public services sites from countries across Asia, Africa, Europe, Australia and the Americas.

Few days back, hackers break into the PKNIC site using SQL Injection vulnerability and changed the DNS records that results in hundreds of Top level pakistani domains hijack which includes Google , Microsoft, paypal and more domains.
