Cyber law experts asks why CERT-In removed advisory warning about WhatsApp vulnerability

Cyber law experts have asked the government to explain why the Indian computer emergency response team (CERT-In) removed from its website two days ago an advisory it had put out in May warning users of a vulnerability that could be used to exploit WhatsApp on their smartphones.

“This is merely further evidence that the explanation is to be provided by GoI (Government of India) instead of blame shifting and politicizing the issue,” said Mishi Choudhary, the legal director of the New York-based Software Freedom Law Center. “India is a surveillance state with no judicial oversight.”

On the missing web page note, CERT-In had provided a detailed explanation of the vulnerability, which could be exploited by an attacker by making a decoy voice call to a target.

It had warned WhatsApp users that the vulnerability could allow an attacker to access information on the system, such as logs, messages and photos, and could further compromise it. CERT-In rated the severity “high” and asked users to upgrade to the latest version of the app.

It also listed links to hackernews and cyber security firm Check Point Software that pointed to the alleged involvement of Israeli cyber software firm NSO Group in the hacking of WhatsApp messenger.

CERT-In Director-General Sanjay Bahl did not respond to ET’s mails or calls seeking clarity on why the advisory was pulled from its website.

The Times of India reported first the development.

The government had blamed WhatsApp for not informing it about the attack and asked the Facebook-owned company to respond by November 4.

In response, WhatsApp sources pointed out that it had informed CERT-in in May about the vulnerability and updated in September that 121 Indian nationals were targeted using the exploit, ET reported on Sunday.

“We should not read too much into it. It could just be bad website management. The vulnerability was public knowledge. It was reported by the Common Vulnerabilities and Exposures (CVE) organization in May,” said Pranesh Prakash, fellow at the Centre of Internet and Society, a non-profit organisation.

The government has also questioned the timing of the disclosure, as it comes amid a request by it to the Supreme Court seeking three months to frame rules to curb misuse of social media in the country.

The government has categorically told WhatsApp that it wants the platform to bring in a mechanism that would enable tracing of the origin of messages, a demand that the instant messaging platform has resisted citing privacy concerns.
