Data breaches bring cyber security into focus

Mega cyber attacks such as “WanCrypt” and “Petya” this year forced governments and enterprises globally, including in India, to focus and invest more on bolstering their security networks. In the first major attack of the year, the world reeled under “WanCrypt” that locked files on computers. Hundreds of thousands of computers were infected with the malware in May.

The primary reason for this attack being successful was not the software but human error. On March 14 this year, Microsoft released a security update which addressed the vulnerability in the 16-year-old Windows XP operating system.

Once the patch for the vulnerability was released, hacker group “Shadow Brokers” exploited this loophole and wreaked havoc in 150 countries. Those who installed the update were saved, while several who did not, fell prey to the attack.

Soon after the “WaCrypt” attack, tens of thousands of computers globally were affected by the “Adylkuzz attack” that shut down SMB networking to prevent further infections with other malware (including the WanCrypt worm).

While Europe and major parts of the world struggled with another big ransomware attack called “Petya”, India also bore the brunt. Some Indian servers were down owing to the Petya attack.

The Shipping Ministry said operations at one of the container termils at Mumbai’s Jawaharlal Nehru Port Trust (JNPT) was affected by Petya. Companies like Genesis BM, a public relations firm, had to shut down systems in India after their intertiol servers were attacked.

In May, a malware called “Judy” hit over 36.5 million Android-based phones, making its way through Google Play Store. In August, the “Locky” ransomware sent over 23 million emails with the malware to the US workforce in just 24 hours. It scrambled the contents of millions of computers and demanded payment to unlock it.

A group of hackers leaked the “Game of Thrones” script, along with 1.5TB of HBO data that included other popular TV shows. Hackers also penetrated Equifax — one of the largest credit bureaus in the world — and stole persol data of 145 million people. Accountancy firm Deloitte was also targeted by a sophisticated hack that compromised the confidential emails and plans of some of its blue-chip clients and the attack went unnoticed for months.

In November, Yahoo agreed that it was attacked in 2013 wherein crimils had information about all three billion accounts. In another massive attack, hackers stole the persol data of 57 million customers and drivers from Uber Technologies. The breach was concealed for more than a year.

Most companies fall victim to cyber attackers either because of unpatched software with known vulnerabilities or because of the human factor like people falling victim to phishing emails, cyber security firm F-Secure said. Cyber security company FireEye said Chinese advanced persistent threat (APT) groups that have allegedly been creating cyber havoc intertiolly will shift their focus in 2018 to countries like India and Hong Kong and groups seen as a threat to Beijing’s influence over global markets. Slowly becoming aware of emerging cyber threats, organisations worldwide will spend $96.3 billion on security in 2018 — an increase of eight per cent from 2017, according to a Gartner forecast. More than 60 per cent of organisations globally will invest in multiple data security tools by 2020 — up from 35 per cent today, it added. To ward off future attacks, the Indian government set up NIC-CERT centre to monitor, detect and prevent cyber attacks on government networks. NIC-CERT will work in close coordition and collaboration with sectoral CERTs and CERT-In. (IANS)
