Hackers target smartphones to mine cryptocurrencies

Paris, Aug 23: Has your smartphone suddenly slowed down, warmed up and the battery drained down for no apparent reason? If so, it may have been hijacked to mine cryptocurrencies.

This new type of cyberattack is called "cryptojacking" by security experts.

It "consists of entrapping an internet server, a personal computer or a smartphone to install malware to mine cryptocurrencies," said Gerome Billois, an expert at the IT service management company Wavestone.

Mining is basically the process of helping verify and process transactions in a given virtual currency. In exchange miners are now and then rewarded with some of the currency themselves.

Legitimate mining operations link thousands of processors together to increase the computing power available to earn cryptocurrencies.

Mining bitcoin, ethereum, monero and other cryptocurrencies may be very profitable, but it does require considerable investments and generates huge electricity bills.

But hackers have found a cheaper option: surreptitiously exploiting the processors in smartphones.

To lure victims, hackers turn to the digital world's equivalent of the Trojan horse subterfuge of Greek mythology: inside an innocuous-looking app or programme hides a malicious one.

The popularity of games makes them attractive for hackers.

"Recently, we have discovered that a version of the popular game Bug Smasher, installed from Google Play between one and five million times, has been secretly mining the cryptocurrency monero on users' devices," said researchers at IT security firm ESET.

Growing number of attacks

The phenomenon is apparently growing.

"More and more mobile applications hiding Trojan horses associated to a cryptocurrency mining programme have appeared on the platforms in the last 12 months," said David Emm, a security researcher at Kaspersky Lab, a leading supplier of computer security and anti-virus software.

"On mobiles the processing power available to criminals is less," but "there is a lot more of these devices, and therefore taking in total, they offer a greater potential," he added.

But for smartphone owners, the mining is at best a nuisance, slowing down the operation of the phone and making it warm to the touch as the processor struggles to unlock cryptocurrency and accomplish other task.

At worst, it can damage the phone.

"On Android devices, the computational load can even lead to 'bloating' of the battery and thus to physical damage to, or destruction of, the device," said ESET.

However, "users are generally unaware" they have been cryptojacked, said Emm.

Cryptojacking affects mostly smartphones running Google's Android operating system.

Apple exercises more control over apps that can be installed on its phones, so hackers have targetted iPhones less.

But Google recently cleaned up its app store, Google Play, telling developers that it will no longer accept apps that mine cryptocurrencies on its platform.

"It is difficult to know which applications to block," said Pascal Le Digol, the country manager in France for US IT security firm WatchGuard, given that "there are new ones every day."

Moreover, as the miners try to "be as discreet as possible" the apps do not stand out immediately, he added.

How to save your phone

There are steps to take to protect one's phone.

Besides installing an antivirus programme, it is important "to update your Android phone" to the latest version of the operating system available to it, said online fraud expert Laurent Petroque at F5 Networks.

He also noted that "people who decide to download apps from non-official sources are at more risk of inadvertently downloading a malicious app".

Defending against cyberattacks of all kinds is "a game of cat and mouse", said Le Digol at WatchGuard. "You need to constantly adapt to the evolution of threats."

In this case he said "the mouse made a large leap", said Le Digol, adding cryptojacking could evolve to other forms in the future to include all types of connected objects.

New Delhi, Jun 18: Vodafone Idea on Thursday told the Supreme Court that it has incurred Rs 1 lakh crore losses as it insisted it is not in a position to furnish bank guarantees.

A bench comprising Justices Arun Mishra, S. Abdul Nazeer, and M.R. Shah, taking up the adjusted gross revenue (AGR) matter through video conferencing, directed the telecom companies to submit their financial documents and books for the last 10 years.

Asking Vodafone if it was a foreign company, the bench said that how can the company say it would not furnish any bank guarantee.

"What if you fly away overnight in future without paying anything?" it asked.

Senior advocate Mukul Rohatgi, representing Vodafone Idea, denied his client is a completely foreign firm and cited before the bench its tie-ups and investments.

Vodafone owes over Rs 58,000 crore as AGR dues and so far, has paid close to Rs 7,000 crore.

Rohatgi contended before the court that the telecom company is in a tough situation, and cannot furnish any fresh bank guarantee, as profits have eluded the company in past many quarters. He submitted before the bench that Rs 15,000 crore bank guarantees are lying with the government, and his client's losses are over Rs 1 lakh crore.

"I cannot offer any more surety," he informed the bench.

Justice Mishra noted that this is public money and these dues should be recovered. "Do not tell us that you will pay if you were to make profits... the money must come," he noted.

Justice Shah observed that the telecom industry is the only industry which earned during the Covid-19 pandemic. "After all, this money will be used for public welfare", he said.

Rohatgi argued that his client would have to fold up if orders were issued to clear dues tomorrow. "11,000 employees will have to go without notice, as we cannot pay them," he added.

Senior advocate Abhishek Manu Singhvi, appearing for Bharti Airtel, contended before the court that out of Rs 21,000 crore AGR dues, the company has already deposited a sum of Rs 18,000 crore.

He argued that his client has given a bank guarantee, in excess of demand, to DoT, and supported the proposal for phased repayment of remaining AGR dues. He insisted that the company needs to sit down with the government and calculate the dues. Airtel owes Rs 25,976 crore after paying Rs 18,000 crore, as per the government.

Senior advocate Arvind Datar, representing Tata Telecom, informed the bench that his client has paid Rs 6,504 crore in AGR dues so far, and furnishing a bank guarantee may adversely impact investments in the sector.

The total AGR dues are close to Rs 1.5 lakh crore.

The top court will now take up the matter in the third week of July.

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.

Bengaluru, Jul 28: Congress leader Siddaramaiah on Monday alleged that BJP is trying to destabilise the Congress government in Rajasthan.

"It is the duty of the Governor to act according to the decision of the state cabinet. But he is acting like a central government puppet," he said at a protest organised here by Karnataka Pradesh Congress Committee (KPCC).

He said the Congress is protesting across the country to save democracy and save the constitution.

"We are not fighting through violence. We are protesting peacefully. The Constitution has given the right to protest in a democratic system," he said.

He accused the BJP of "being disrespectful" to the Constitution.

"Governments must walk within the framework of the Constitution. The Constitution gives everyone rights and duties. BJP destabilises elected governments and buys our legislators by horse-trading by spending crores of money. The same thing happened in Karnataka as well," he alleged.
