Security researchers have discovered that the Smominru malware infected 90,000 machines worldwide during the month of August, with an infection rate of up to 4,700 computers per day.

In its post-infection phase, it steals victim credentials, installs a Trojan module and a cryptominer and propagates inside the network, according to researchers from Guardicore, a data centre and cloud security company.

The botnet uses several methods to propagate, but primarily it infects a system in one of two ways -- either by brute-forcing weak credentials for different Windows services, or more commonly by relying on the infamous EternalBlue exploit, cybersecurity firm Kaspersky said in a blog post last week.

Even though Microsoft patched the vulnerability EternalBlue exploits, which made the WannaCry and NotPetya outbreaks possible, many companies are simply ignoring updates, Kaspersky said.

China, Taiwan, Russia, Brazil and the US have seen the most attacks, but that doesn't mean other countries are out of its scope. For example, the largest network Smominru targeted was in Italy, with 65 hosts infected.

The criminals involved are not too particular about their targets, which range from universities to healthcare providers.

However, one detail is very consistent. About 85 per cent of infections occur on Windows 7 and Windows Server 2008 systems. The rest include Windows Server 2012, Windows XP and Windows Server 2003.

After compromising the system, Smominru creates a new user, called admin$, with admin privileges on the system and starts to download a whole bunch of malicious payloads.

The most obvious objective is to silently use infected computers for mining cryptocurrency (namely, Monero) at the victim's expense.

The malware also downloads a set of modules used for spying, data exfiltration, and credential theft.

On top of that, once Smominru gains a foothold, it tries to propagate further within the network to infect as many systems as possible.

To protect their network, computers, and data from Smominru, users need to update operating systems and other software regularly, Kaspersky said.

It is also important for users to use strong passwords. A reliable password manager that helps you create, manage, and automatically retrieve and enter passwords may help protect you against brute-force attacks.

Google on Monday announced it is gradually winding down its free public Wi-Fi Station programme currently available at over 400 railway stations in India, and will work with the Indian Railways and Railtel Corporation to help them with existing sites so they can remain useful resources for people.

Google launched its Station initiative in India in 2015 to bring fast, free public Wi-Fi to over 400 of the busiest railway stations in the country by mid-2020.

"We crossed that number by June 2018 and implemented Station in thousands of other locations around the country in partnership with telecommunications companies, ISPs and local authorities," Caesar Sengupta, Vice President, Payments and Next Billion Users, Google, said in a statement.

"Over time, partners in other countries asked for Station too and we responded accordingly. We're grateful for these partnerships, especially with the Indian Railways and the Government of India, that helped us serve millions of users over the last few years," he added.

According to Google, the decision to shut Station has been taken keeping the affordable mobile data plans and mobile connectivity in mind that is improving globally including in India.

"India, specifically now has among the cheapest mobile data per GB in the world, with mobile data prices having reduced by 95 per cent in the last 5 years, as per TRAI in 2019," said Sengupta.

The Indian users consume close to 10GB of data, each month, on average, according to reports.

"Our commitment to supporting the next billion users remains stronger than ever, from continuing our efforts to make the internet work for more people and building more relevant and helpful apps and services," Sengupta noted.

Global networking giant Cisco last year teamed up with Google to roll out free, high-speed public Wi-Fi access globally, starting with India.

The first pilot under the partnership was rolled out at 35 locations in Bengaluru.

Sengupta said that in addition to the changed context, the challenge of varying technical requirements and infrastructure among our partners across countries has also made it difficult for Station to scale and be sustainable, especially for our partners.

"And when we evaluate where we can truly make an impact in the future, we see greater need and bigger opportunities in building products and features tailored to work better for the next billion user markets," he said.

Giving each and every app access to personal information stored on Android smartphones such as your contacts, call history, SMS and photos may put you in trouble as bad actors can easily use these access to spy on you, send spam messages and make calls anywhere at your expense or even sign you up for a premium "service", researchers from cybersecurity firm Kaspersky have warned.

But one can restrict access to such information as Android lets you configure app permissions. 

Giving an app any of these permissions generally means that from now on it can obtain information of this type and upload it to the Cloud without asking your explicit consent for whatever it intends to do with your data.

Therefore, security researchers recommend one should think twice before granting permissions to apps, especially if they are not needed for the app to work. 

For example, most games have no need to access your contacts or camera, messengers do not really need to know your location, and some trendy filter for the camera can probably survive without your call history, Kaspersky said. 

While decision to give permission is yours, the fewer access you hand out, the more intact your data will be.

Here's what you should know to protect your data.

SMS: An app with permission to send and receive SMS, MMS, and WAP (Wireless Application Protocol) push messages, as well as view messages in the smartphone memory will be able to read all of your SMS correspondence, including messages with one-time codes for online banking and confirming transactions.

Using this permission, the app can also send spam messages in your name (and at your expense) to all your friends. Or sign you up for a premium "service." You can see and conrol which apps have these rights by going to the settings of your phone.

Calendar: With permission to view, delete, modify, and add events in the calendar, prying eyes can find out what you have done and what you are doing today and in the future. Spyware loves this permission.

Camera: Permission to access the camera is necessary for the app to take photos and record video. But apps with this permission can take a photo or record a video at any moment and without warning. Attackers armed with embarrassing images and other dirt on you can make life a misery, according to Kaspersky.

Contacts: With permission to read, change, and add contacts in your address book, and access the list of accounts registered in the smartphone, an app can send your entire address book to its server. Even legitimate services have been found to abuse this permission, never mind scammers and spammers, for whom it is a windfall.

This permission also grants access to the list of app accounts on the device, including Google, Facebook, and many other services.

Phone: Giving access to your phone means permission to view and modify call history, obtain your phone number, cellular network data, and the status of outgoing calls, add voicemail, access IP telephony services, view numbers being called with the ability to end the call or redirect it to another number and call any number.

This permission basically lets the app do anything it likes with voice communication. It can find out who you called and when or prevent you from making calls (to a particular number or in general) by constantly terminating calls. 

It can eavesdrop on your conversations or, of course, make calls anywhere at your expense, including to pay-through-the-nose numbers, Kaspersky warned.

Mumbai, Jun 27: The Bombay High Court observed that COVID-19 patients from poor and indigent sections cannot be expected to produce documentary proof to avail subsidised or free treatment while getting admitted to hospitals.

The court on Friday was hearing a plea filed by seven residents of a slum rehabilitation building in Bandra, who had been charged ₹ 12.5 lakh by K J Somaiya Hospital for COVID-19 treatment between April 11 and April 28.

The bench of Justices Ramesh Dhanuka and Madhav Jamdar directed the hospital to deposit ₹10 lakh in the court.

The petitioners had borrowed money and managed to pay ₹10 lakh out of ₹12.5 lakh that the hospital had demanded, after threatening to halt their discharge if they failed to clear the bill, counsel Vivek Shukla informed the court.

According to the plea, the petitioners were also overcharged for PPE kits and unused services.

On June 13, the court had directed the state charity commissioner to probe if the hospital had reserved 20% beds for poor and indigent patients and provided free or subsidised treatment to them.

Last week, the joint charity commissioner had informed the court that although the hospital had reserved such beds, it had treated only three poor or indigent persons since the lockdown.

It was unfathomable that the hospital that claimed to have reserved 90 beds for poor and indigent patients had treated only three such persons during the pandemic, advocate Shukla said.

He further argued that COVID-19 patients, who are in distress, cannot be expected to produce income certificate and such documents as proof.

However, senior advocate Janak Dwarkadas, who represented the hospital, said the petitioners did not belong to economically weak or indigent categories and had not produced documents to prove the same.

A person who is suffering from a disease like COVID-19 cannot be expected to produce certificates from a tehsildar or social welfare officer before seeking admission in the hospital, the bench noted and asked the hospital to deposit ₹10 lakh in court within two weeks.
