The Web site of IndiaTimes, the online news site of the Times Group, one of India's large news and entertainment groups, exposed visitors to malware, according to an advisory by ScanSafe.
In her blog, Mary Landesman, a researcher at ScanSafe, said that the company had contacted IndiaTimes by email and by phone on Thursday.
"Unfortunately, the person we spoke with indicated that it was a holiday in India and they would be unlikely to fix the problem until Monday," she said.
Most of India was on holiday from Thursday because of the Diwali festival. The IndiaTimes Web site was however updated through the week. It is not clear at this point whether the site still contains malware.
IndiaTimes, a part of Times Internet in Gurgaon, was not available for comment Monday.
ScanSafe first detected and blocked malware on the site on October 25. ScanSafe is still investigating the reach of this attack, but given the popularity of the site and the amount of malware involved, the company is urging caution, it said in its advisory. Only certain pages of the Indiatimes.com are infected, the advisory added.
In September, the site of the Bank of India, a large Indian bank in Mumbai, was hacked into and was dispensing malicious code. The bank site had to be brought down before the malware could be removed.
