Indian IT services company, Wipro, recently sensed some abnormal activity in a few employee accounts on its network, owing to an advanced phishing campaign. The cyber attack was first reported by a blog. Expressing concern over its employee accounts being compromised, the Company has already begun investigating the issue with the help of a forensic organisation, and is also looking at ways to control any adverse potential impact. A cyber security blog, KrebsOnSecurity, revealed that Wipro's systems had been penetrated and the data was being misused to attack its clients. The blog also stated that not less than a dozen clients' systems were being targeted through the Company's systems. According to the blog Wipro's internal e-mail system had also been compromised, but the Company denies this. The cyber attack was described as a 'zeroday attack', that is, an attack on the very day that a software weakness is detected. Such an attack makes it difficult to fix the breach.
