Ransomware threat: Get patched, find a firewall or upgrade fast

May 15, 2017

New Delhi, May 15: It was coming. On March 14 this year, Microsoft released a security update which addressed the vulnerability in the 16-year-old Windows XP operating system that the hackers behind the massive ransomware attack exploited and created havoc in 150 countries.

The vulnerability in the Microsoft Windows software — exploited by “WannaCrypt” — crippled computers from hospitals in Britain to police stations in India, with hackers demanding hundreds of dollars from the users for them to regain control over their data.

Once Microsoft released the patch for the vulnerability — exploited by hacker group “Shadow Brokers” after stealing a software from the US National Security Agency (NSA) — some Window XP users installed the update called “Microsoft Security Bulletin MS17-010” on their desktops and laptops.

But several didn"t.

There are nearly 150 million computers running Windows XP operation system globally. Those who didn"t pay heed to the Windows XP patch are the ones who have fallen prey to the world"s biggest ransomware attack.

Microsoft which had discontiued security updates to its out-of-date software, has also provided a security update for all customers using Windows 8 and Windows Server 2003, anticipating further attacks on these earlier platforms being used by millions.

According to the company, “customers who are running supported versions of the operating system (Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2012 R2, Windows Server 2016) will have received the security update MS17-010 in March.

“If customers have automatic updates enabled or have installed the update, they are protected. For other customers, we encourage them to install the update as soon as possible,” said Phillip Misner, Principal Security Group Manager, Microsoft Security Response Centre, in a statement.

Meanwhile, “WannaCrypt” locked up machines, encrypted files and demanded approximately $600 in Bitcoin for a recovery key.

According to global cyber security firms, paying heed to updates can only save your data from being put to ransom.

“Install the official patch from Microsoft that closes the vulnerability used in the attack. Ensure that security solutions are switched on all nodes of the network. If Kaspersky Lab"s solution is used, ensure that it includes the "System Watcher", a behavioural proactive detection component and that it is switched on,” Altaf Halde, Managing Director of Kaspersky Lab (South Asia), told.

“Run the "Critical Area Scan" task in Kaspersky Lab"s solution to detect possible infection as soon as possible (otherwise it will be detected automatically, if not switched off, within 24 hours),” he added.

According to Subhendu Sahu, Acting Country Manager for India, FireEye, the ransomware poses high risks to organisations using potentially vulnerable Windows machines.

“We can certainly expect follow-on attacks. Organisations seeking to take risk management steps related to this campaign should install the latest Windows patches. They should also use the indicators of compromise which are associated with this activity. FireEye has also taken steps to help secure its customers,” Sahu told.

As investigators were working to track down those responsible for the ransomware attack, Microsoft President and Chief Legal Officer Brad Smith said the governments should treat this attack as a “wake-up call”.

The news led software security providers to ramp up anti-malware software.

“Upon learning of these incidents, McAfee quickly began working to analyse samples of the ransomware and develop mitigation guidance and detection updates for its customers. McAfee has subsequently provided DAT (that contain data in text or binary format) updates to all its customers and provided them and the public further analysis on the attacks,” Ian Yip, Chief Technology Officer, Asia Pacific, McAfee, told.

If you are a home Windows XP user, patch immediately follow up with an upgrade. If you are running a vulnerable system and cannot install the patch for some reason, try doing the following:

“Disable SMBv1 (a server component) with the steps documented at "Microsoft Knowledge Base Article 2696547" and as recommended previously. Consider adding a rule on your router or firewall to block incoming Server Message Block (SMB) traffic on port 445,” said a report in the technology website Engadget.

“This is big and set to get bigger. We haven"t seen anything like this since Conficker in 2008,” Amit Nath, Head of Asia Pacific-Corporate Business at cyber security firm F-Secure Corporation, told IANS.

The Conficker worm infected millions of computers including government, business and home computers in over 190 countries.
Always make sure your files are backed up.

“That way, if they become compromised in a ransomware attack, you can wipe your disk drive clean and restore the data from the backup. Using Cloud storage with anti-virus scanning abilities to share files will help users to mitigate any possible threats,” suggested Anand Ramamoorthy, Managing Director, South Asia, McAfee.

Remember this: “WannaCrypt” probably won"t work across the internet for PCs behind a firewall or router.

“But if a server is connected directly to the internet or a PC is on the same network as an infected computer, it can spread quickly — which is exactly what has happened,” the Engadget report added.

Paris, Jun 16: Increasing numbers of readers are paying for online news around the world even if the level of trust in the media, in general, remains very low, according to a report published Tuesday.

Around 20 percent of Americans questioned said they subscribed to an online news provider (up to four points over the previous year) and 42 percent of Norwegians (up eight points), along with 13 percent of the Dutch (up to three points), compared with 10 percent in France and Germany.

But between a third and a half of all news subscriptions go to just a few major media organisations, such as the New York Times, according to the annual Digital News Report by the Reuters Institute.

Some readers, however, are also beginning to take out more than one subscription, paying for a local or specialist title in addition to a national news source, the study's authors said.

But a large proportion of internet users say nothing could convince them to pay for online news, around 40 percent in the United States and 50 percent in Britain.

YouGov conducted the online surveys of 40 countries for the Reuters Institute in January, with 2,000 respondents in each.

Further surveys were carried out in six countries in April to analyse the initial effects of COVID-19.

The health crisis brought a revival of interest in television news -- with the audience rising five percent on average -- establishing itself as the main source of information along with online media.

Conversely, newspaper circulation was hard-hit by coronavirus lockdown measures.

The survey found trust in the news had fallen to its lowest level since the first report in 2012, with just 38 percent saying they trusted most news most of the time.

However, confidence in the news media varied considerably by country, ranging from 56 percent in Finland and Portugal to 23 percent in France and 21 percent in South Korea.

In Hong Kong, which has been hit by months of sometimes violent street protests against an extradition law, trust in the news fell 16 points to 30 percent over the year.

Chile, which has had regular demonstrations against inequality, saw trust in the media fall 15 percent while in Britain, where society has been polarised by issues such as Brexit, it was down 12 points.

In an unprecedented crisis despite Prime Minister Narendra Modi assuring the continuation of essential services like food and groceries, online marketplaces like Flipkart and Amazon along with delivery platforms like Bigbasket, Grofers and FreshToHomes hit a major blockade on Wednesday as local authorities shut warehouses and sent delivery boys back, even harassed them.

Millions of people across cities were left helpless at homes as essential items like fruits and vegetables, dairy and milk, meat and fish etc did not reach their doors despite placing orders well in advance. Later, the orders went dry.

While Grofers' warehouse in Faridabad was closed by the local law enforcement agencies, Bigbasket complained that the police stopped its delivery partners and "some of them were even beaten up by for no fault of theirs".

"We are not operational due to restrictions imposed by local authorities on movement of goods in spite of clear guidelines provided by central authorities to enable essential services. We are working with the authorities to be back soon,' Bigbasket tweeted.

In a statement to IANS, Bigbasket said that it will help to have better coordination between the Centre and state, and between the state and local police to "ensure that our delivery vans and bikes don't get stopped by the police. Bigbasket and bb daily are not taking new orders".

Furious people stormed the social media platforms, writing their plight to NITI Aayog CEO Amitabh Kant on Twitter.

"Sir, all e-commerce are down. Believe me I tried everything (Grofers, Bigbasket, Flipkart, Amazon, Big Bazaar), no delivery till 31st March or Server Down or No Service. Need to think how we can enable them through digital India," tweeted one user.

Kant tweeted back to Bigbasket: "They should give me specifics - State & location. I will act on it by getting in touch with concerned authorities & sorting it out. Govt guidelines exempt them. We will ensure that citizens are not impacted".

Kant also responded to Grofers: "Cold storages & Warehouses as well as delivery of all essentials goods including food, pharma thru E-Commerce are exempted under MHA order. I have spoken to CS & DGP, Haryana . They have taken immediate action to ensure that supply chains efficiently function for the citizens".

The subscription-based hyperlocal delivery startup FreshToHome sent messages to its customers, saying that despite the government declaring food delivery as essential, "we are facing hardships in continuing our operations".

"Please bear with us as we are working hard to unblock local authority hurdles," said the FreshToHome team.

Reports later surfaced that the Department for Promotion of Industry and Internal Trade (DPIIT) has initiated talks with the state Chief Secretaries asking them not to restrict movement of people engaged in home delivery of essential items, mentioned in the list of exempted items circulated by the Home Ministry.

Meanwhile, Flipkart said it has temporarily suspended its operations and services - including grocery items. The marketplace has decided to halt all orders from March 25 for all three supply chains -- groceries, non-large goods and large items.

"Flipkart has temporarily suspended orders as we assess the possibilities of operating in the lockdown. We are prioritising the safety of our delivery executives and seeking the support of the local governments and police authorities to meet the needs of our customers as they stay home during this lockdown," Rajneesh Kumar, Chief Corporate Affairs Officer, Flipkart, said in a statement.

E-commerce giant Amazon said the company has to "temporarily stop taking orders and disable shipments for lower-priority products.

"For all pending customer orders on lower-priority products, we are reaching out to customers and giving them a choice to cancel their orders, and receive a refund for prepaid items," said the company.

Witnessing a surge in demand, supermarket chain Biz Bazaar entered the fray, with launching doorstep delivery services in major cities like Delhi, Mumbai, Bengaluru and Gurugram.

However, within no time, Big Bazaar was flooded with calls, forcing the company to issue a statement, saying that "In light of the recent announcement, we are receiving an unprecedented number of requests for doorstep delivery. There could be a delay due to the restrictions on movements".

Already battling massive surge in demand, the online delivery platforms faced other issues too, including zero access to several high-rises across the country which have gone under complete lockdown with all entry and exit gates locked.

Facebook will introduce a new notification screen on its platform that will warn users if the article they are about to share is over 90 days old, the company announced on Thursday.

“We’re starting to globally roll out a notification screen that will let people know when news articles they are about to share are more than 90 days old,” Facebook wrote in a blog post.

The social media platform had previously introduced a context button in 2018 that provides information about the sources of articles in the News Feed. Building upon that, the new feature will inform users about the timeliness of the article.

“To ensure people have the context they need to make informed decisions about what to share on Facebook, the notification screen will appear when people click the share button on articles older than 90 days, but will allow people to continue sharing if they decide an article is still relevant,” Facebook said.

The social media giant stated that timeliness is important in understanding the context of an article and curbing the spread of misinformation on the platform.

“News publishers, in particular, have expressed concerns about older stories being shared on social media as current news, which can misconstrue the state of current events. Some news publishers have already taken steps to address this on their own websites by prominently labelling older articles to prevent outdated news from being used in misleading ways,” Facebook added.

Apart from this, the platform will also be testing a similar notification screen for information related to the global Covid-19 pandemic. The notification screen will provide information about the source of the link shared in a post if the link is related to information on Covid-19. It will also direct people to its previously introduced Covid-19 information centre for “authoritative” health information, it said.
