The biggest ransomware attacks hits Indian companies - may 2017

More than 45,000 computers in hospitals, IT organizations, railway station networks, ATMs and even universities across 74 countries have been severely affected by the WannaCryptransomware worm also popularly called Wcry. This is the biggest ransomware attack in recorded history.

The WannaCrypt vulnerability blocks windows files and users need to make payments towards the hackers to restore access. A certain worm spread across systems which run on Windows OS and installs this bug.

But it is critical to notice that Microsoft has already sent across patches around a month ago. But this bug has already affected many systems which had not installed the latest security updates.

The bug was earlier abused by National Security Agency (NSA) to spy on their targets across the world. But in April this year, one of their internal tools called Eternalblue was stolen and leaked online. After that it was used to hack many machines across the internet.

"The exploit known as MS17-010 was previously patched by Microsoft. However, Windows XP machines which no longer receive updates are at particular risk. Machines using current Windows operating systems which have not been patched with March 15 updates are also at risk," says Amit Nath, Head of Asia Pacific - Corporate Business at F-Secure Corporation.

In terms of WannaCrypt's impact on India, Saket Modi, CEO, Lucideus Tech says that this worm can have potential impact on the government. "Most government departments don't have specific different OS for its operations and the same risk factor applies to government too."

According to many independent reports, many Indian companies were affected. Amongst those were systems of Andhra Pradesh police department, manufacturing companies in Delhi, 2 sme's in Delhi and one big corporate house in Mumbai. But certain cyber security experts point out that the actual impact of the attack can be ascertained only when people try logging into their systems on Monday.

Similarly, Nath pointed out that no country is safe from this Ransomware as it can lead to data loss, compromise business and organisations efficiency leading to reputation and financial loss.

An official of the Computer Emergency Response Team (CERT-IN) told ET that so far the agency has not received any reports about the impact in India. "'Our researchers are on the job and trying to figure out if there has been any impact in India," the official said. CERT has already issued an advisory alerting people about the spreading ransomware. "We had also issued an advisory in March, those people who would have acted on it, would be safe," said the official.

Meanwhile CERT-IN has also issued a vulnerability note on its website (CERTIn Vulnerability Note CIVN20170032 Multiple vulnerabilities in Windows SMB Original Issue Date: March 15, 2017) with a Severity Rating of HIGH on March 15, 2017 for possible remote exploitation of this vulnerability and to apply the patch released by Microsoft for the same.

Famous whistleblower Edward Snowden pointed out that "This is a special case. Had @NSAGov disclosed the vuln when they discovered it, hospitals would have had years -- not months -- to prepare."
