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.

US dictionary Merriam-Webster will update the meaning of the word "racism" after being contacted by a Missouri black woman, who claimed the current definition fell short of including the systematic oppression of people of colour, according to media reports.

"A revision to the entry for racism is now being drafted to be added to the dictionary soon, and we are also planning to revise the entries of other words that are related to racism or have racial connotations," according to a statement of the 189-year-old dictionary shared by Kennedy Mitchum, a recent graduate of Drake University in Iowa, on her Facebook.

Mitchum, 22, emailed the dictionary last month, following the death of African American George Floyd in the custody of four Minneapolis police officers, Xinhua news agency reported.

"I kept having to tell them that definition is not representative of what is actually happening in the world," Mitchum told CNN. "The way that racism occurs in real life is not just prejudice, it's the systemic racism that is happening for a lot of black Americans."

Merriam-Webster's first definition of racism is "a belief that race is the primary determinant of human traits and capacities and that racial differences produce an inherent superiority of a particular race."

"It's not just disliking someone because of their race," Mitchum wrote in a Facebook post on Friday. "This current fight we are in is evidence of that, lives are at stake because of the systems of oppression that go hand-in-hand with racism."

Los Angeles, Apr 28: People who experience loss of smell as one of the COVID-19 symptoms are likely to have a mild to moderate clinical course of the disease, according to a study which may help health care providers determine which patients require hospitalisation.

The findings, published in the journal International Forum of Allergy & Rhinology, follows an earlier study that validated the loss of smell and taste as indicators of infection with the novel coronavirus, SARS-CoV-2.

According to the scientists from the University of California (UC) San Diego Health in the US, patients who reported loss of smell were 10 times less likely to be hospitalised for COVID-19 compared to those without the symptom.

"One of the immediate challenges for health care providers is to determine how to best treat persons infected by the novel coronavirus," said Carol Yan, first author of the current study and rhinologist from the UC San Diego Health.

"If they display no or mild symptoms, can they return home to self-quarantine or will they likely require hospitalisation? These are crucial questions for hospitals trying to efficiently and effectively allocate finite medical resources," Yan said.

The findings, according to the researchers, suggest that loss of smell may be predictive of a milder clinical course of COVID-19.

"What's notable in the new findings is that it appears that loss of smell may be a predictor that a SARS-CoV-2 infection will not be as severe, and less likely to require hospitalisation," Yan said.

"If an infected person loses that sense, it seems more likely they will experience milder symptoms, barring other underlying risk factors," she added.

Risk factors for COVID-19 previously reported by other studies include age, and underlying medical conditions, such as chronic lung disease, serious heart conditions, diabetes, and obesity.

In the current study, the scientists made a retrospective analysis between March 3 and April 8 including 169 patients who tested positive for COVID-19 at UC San Diego Health.

They assessed olfactory and gustatory data for 128 of the 169 patients, 26 of whom required hospitalisation.

According to the researchers, patients who were hospitalised for COVID-19 treatment were significantly less likely to report anosmia or loss of smell -- 26.9 per cent compared to 66.7 per cent for COVID-19-infected persons treated as outpatients.

Similar percentages were found for loss of taste, known as dysgeusia, they said.

"Patients who reported loss of smell were 10 times less likely to be admitted for COVID-19 compared to those without loss of smell," said study co-author Adam S. DeConde.

"Moreover, anosmia was not associated with any other measures typically related to the decision to admit, suggesting that it's truly an independent factor and may serve as a marker for milder manifestations of Covid-19," DeConde said.

The researchers suspect that the findings hint at some of the physiological characteristics of the infection.

"The site and dosage of the initial viral burden, along with the effectiveness of the host immune response, are all potentially important variables in determining the spread of the virus within a person and, ultimately, the clinical course of the infection," DeConde said.

If the SARS-CoV-2 virus initially concentrates in the nose and upper airway, where it impacts olfactory function, that may result in an infection that is less severe and sudden in onset, decreasing the risk of overwhelming the host immune response, respiratory failure, and hospitalisation, the scientists added.

"This is a hypothesis, but it's also similar to the concept underlying live vaccinations," DeConde explained.

"At low dosage and at a distant site of inoculation, the host can generate an immune response without severe infection," he added.

Loss of smell, according to the study, might also indicate a robust immune response which has been localised to the nasal passages, limiting effects elsewhere in the body.

Citing the limitations of the study, the scientists said they relied upon self-reporting of anosmia from participants, which posed a greater chance of recall bias among patients once they had been diagnosed with COVID-19.

They added that patients with more severe respiratory disease requiring hospitalisation may not be as likely to recognise or recall the loss of smell.

So the researchers said more expansive studies are needed for validating the results.

The GST Council is unlikely to make major changes in the indirect tax structure at its next meeting slated mid June.

A top government source said that the Centre is not in favour of increasing tax rates on any goods or service as it could further impact consumption and demand that is already suppressed due the COVID-19 pandemic and lockdown.

It was widely expected that the GST Council could consider raising tax rates and cess on certain non-essential items to boost revenue for states and the Centre. Several states have reportedly taken an over 80-90 per cent hit in GST collections in April, the official data for which has not yet been released by the Centre.

"The need of the hour is to boost consumption and improve demand. By categorising items into essential and non-essential and then raising taxes on non-essential is not what Centre favours. But, the issue on rates and relief will be decided by the GST Council that is meeting next month," the finance ministry official source quoted above said.

The GST Council is chaired by the Union finance minister and thus the views of the Centre play out strongly in the council meetings.

However, the Council will also have to balance the expectations of the states whose revenues have nosedived after the coronavirus outbreak and wide scale disruption to businesses while they have still not been paid GST compensation since the December-January period.

To the question of wider scale job losses in the period of lockdown as businesses get widely impacted, the official said that the Finance Ministry has asked the labour ministry to collect data on job losses during Covid-19 and is constantly engaging with the ministry to oversee job losses and salary cuts.

On restrictions put on Chinese investment in India, the official clarified that no decision had yet been taken to restrict China through the Foreign Portfolio Investment (FPI) route.

Asked about monetising government debt, the official said that the issue would be looked at when we reach a stage. It has not come to that stage yet.

In the government's over Rs 20 lakh crore economic package, the official defended its structure while suggesting that comparisons with the economic packages of other countries should not be drawn as India's needs were different from others.

"We have gone in more reforms that is needed to give strength to the economy. This is required more in our country," the official source said.
