Virus targets the social network in new fraud twist

August 18, 2013

Virus_targetsBoston, Aug 18: In the world of cyber fraud, a fake fan on Instagram can be worth five times more than a stolen credit card number.

As social media has become increasingly influential in shaping reputations, hackers have used their computer skills to create and sell false endorsements - such as "likes" and "followers" - that purport to come from users of Facebook, its photo-sharing app Instagram, Twitter, Google's YouTube, LinkedIn and other popular websites.

In the latest twist, a computer virus widely used to steal credit card data, known as Zeus, has been modified to create bogus Instagram "likes" that can be used to generate buzz for a company or individual, according to cyber experts at RSA, the security division of EMC Corp.

These fake "likes" are sold in batches of 1,000 on Internet hacker forums, where cyber criminals also flog credit card numbers and other information stolen from PCs. According to RSA, 1,000 Instagram "followers" can be bought for $15 and 1,000 Instagram "likes" go for $30, whereas 1,000 credit card numbers cost as little as $6.

It may seem odd that fake social media accounts would be worth more than real credit card numbers, but online marketing experts say some people are willing to spend heavily to make a splash on the Internet, seeking buzz for its own sake or for a business purpose, such as making a new product seem popular.

"People perceive importance on what is trending," said Victor Pan, a senior data analyst with WordStream, which advises companies on online marketing. "It is the bandwagon effect."

Facebook, which has nearly 1.2 billion users, said it is in the process of beefing up security on Instagram, which it bought last year for $1 billion. Instagram, which has about 130 million active users, will have the same security measures that Facebook uses, said spokesman Michael Kirkland.

He encouraged users to report suspicious activity through links on Facebook sites and apps.

"We work hard to limit spam on our service and prohibit the creation of accounts through unauthorized or automated means," Kirkland said.

KNOWING WHEN TO STOP

The modified Zeus virus is the first piece of malicious software uncovered to date that has been used to post false "likes" on a social network, according to experts who track cyber crime.

Fraudsters most commonly manipulate "likes" using automated software programs.

The modified version of Zeus controls infected computers from a central server, forcing them to post likes for specific users. They could also be given marching orders to engage in other operations or download other types of malicious software, according to RSA.

Cyber criminals have used Zeus to infect hundreds of millions of PCs since the virus first surfaced more than five years ago, according to Don Jackson, a senior security researcher with Dell SecureWorks.

That the virus is now being adapted to target Instagram is a sign of the rising importance of social media in marketing, and the increasing sophistication of hackers trying to profit from the trend.

Online marketing consultant Will Mitchell said he sometimes advises clients to buy bogus social-networking traffic, but only to get an early foothold online.

When asked about the ethics of faking endorsements, Mitchell replied, "It's fine to do for the first 100, but I always advise stopping after that."

He said one of his clients once bought more than 300,000 "likes" on Facebook against his advice, a move that Mitchell felt damaged the client's reputation. "It was just ridiculous," he said. "Everybody knew what they were doing."

Still, experts say schemes to manipulate social networks are unlikely to go away. Creating fake social media accounts can also be used for more nefarious purposes than creating fake "likes," such as identity theft.

"The accounts are always just a means to an end. The criminals are always looking to profit," said computer security expert Chris Grier, a University of California at Berkeley research scientist who spent a year working on a team that investigated fake accounts on Twitter.

Toronto, May 7: Scientists have uncovered how bats can carry the MERS coronavirus without getting sick, shedding light on what triggers coronaviruses, including the one behind the COVID-19 pandemic, to jump to humans.

According to the study, published in the journal Scientific Reports, coronaviruses like the Middle East respiratory syndrome (MERS) virus, and the COVID19-causing SARS-CoV-2 virus, are thought to have originated in bats.

While these viruses can cause serious, and often fatal disease in people, bats seem unharmed, the researchers, including those from the University of Saskatchewan (USask) in Canada, said.

"The bats don't get rid of the virus and yet don't get sick. We wanted to understand why the MERS virus doesn't shut down the bat immune responses as it does in humans," said USask microbiologist Vikram Misra.

In the study, the scientists demonstrated that cells from an insect-eating brown bat can be persistently infected with MERS coronavirus for months, due to important adaptations from both the bat and the virus working together.

"Instead of killing bat cells as the virus does with human cells, the MERS coronavirus enters a long-term relationship with the host, maintained by the bat's unique 'super' immune system," said Misra, one of the study's co-authors.

"SARS-CoV-2 is thought to operate in the same way," he added.

Stresses on bats, such as wet markets, other diseases, and habitat loss, may have a role in coronavirus spilling over to other species, the study noted.

"When a bat experiences stress to their immune system, it disrupts this immune system-virus balance and allows the virus to multiply," Misra said.

The scientists, involved in the study, had earlier developed a potential treatment for MERS-CoV, and are currently working towards a vaccine against COVID-19.

While camels are the known intermediate hosts of MERS-CoV, they said bats are suspected to be the ancestral host.

There is no vaccine for either SARS-CoV-2 or MERS, the researchers noted.

"We see that the MERS coronavirus can very quickly adapt itself to a particular niche, and although we do not completely understand what is going on, this demonstrates how coronaviruses are able to jump from species to species so effortlessly," said USask scientist Darryl Falzarano, who co-led the study.

According to Misra, coronaviruses rapidly adapt to the species they infect, but little is known on the molecular interactions of these viruses with their natural bat hosts.

An earlier study had shown that bat coronaviruses can persist in their natural bat host for at least four months of hibernation.

When exposed to the MERS virus, the researchers said, bat cells adapt, not by producing inflammation-causing proteins that are hallmarks of getting sick, but instead by maintaining a natural antiviral response.

On the contrary, they said this function shuts down in other species, including humans.

The MERS virus, the researchers said, also adapts to the bat host cells by very rapidly mutating one specific gene.

These adaptations, according to the study, result in the virus remaining long-term in the bat, but being rendered harmless until something like a disease, or other stressors, upsets this balance.

In future experiments, the scientists hope to understand how the bat-borne MERS virus adapts to infection and replication in human cells.

"This information may be critical for predicting the next bat virus that will cause a pandemic," Misra said.

New Delhi, Jun 12: The Supreme Court on Friday asked Solicitor General Tushar Mehta to convene a meeting of the Finance Ministry and RBI officials over the weekend to decide whether interest incurred on EMIs during the moratorium period can be charged by banks.

A bench comprising Justices Ashok Bhushan, Sanjay Kishan Kaul and M.R. Shah queried Mehta as the court was concerned since the Centre has deferred loan for three months.

"Then how can interest of these 3 months be added?" the apex bench asked. Mehta replied: "I need to sit down with the RBI officials and have a meeting."

SBI's counsel, senior advocate Mukul Rohatgi, intervened during the proceedings and said "all banks are of the view that interest cannot be waived for a six month EMI moratorium period".

"We need to discuss it with the RBI," insisted Rohatgi.

Justice Bhushan then asked Mehta to convene a meeting of the RBI and Finance Ministry officials over the weekend, and listed the matter for further hearing on June 17.

The top court, during the hearing, indicated that it was not considering a complete waiver of interest but was only concerned that postponement of interest shouldn't accrue further interest on it.

After the RBI said the waiver of interest charges on EMIs during moratorium will lead to loss of 1 per cent of the nation's GDP, the top court had earlier asked the Finance Ministry to reply, whether the interest could be waived or it would continue during the moratorium period.

The top court said these are not normal times, and it is a serious issue, as on one hand moratorium is granted and then, the interest is charged on loans during this period.

"There are two issues in this (matter). No interest during the moratorium period and no interest on interest," said Justice Bhushan. The observation from the bench came on a petition by Gajendra Sharma, in which he sought a direction to declare portion of the RBI's March 27 notification as ultra vires to the extent it charged interest on the loan amount during the moratorium period.

Mumbai, Jun 12: Following an overwhelming response for the mega rights issue of Mukesh Ambani-owned Reliance Industries, the partly paid-up rights shares are set to debut on stock exchanges on June 15.

The biggest ever Rs 53,124 crore rights issue was subscribed 1.59 times and received bids worth Rs 84,000 crore on June 3.

Reliance said the rights issue saw a huge investor interest, including from lakhs of small investors and thousands of institutional investors, both Indian and foreign.

In 2019, Ambani said in the Reliance's annual general meeting that the company will be net zero debt by March 2021. The company is on course to achieve its target ahead of the deadline.

"In spite of the COVID-19 crisis and the lockdowns, the due-diligence by Saudi Aramco for the planned investment in the O2C business is on track as both the parties are committed and actively engaged," he said recently.

"With a strong visibility to these equity infusions, Reliance is set to achieve net zero debt status ahead of its own aggressive timeline. We believe rights issue was a part of the company's strategy of deleveraging its balance sheet," said Ambani.
