When ads become dangerous

Over the past months, the BBC, the New York Times, and other major news and commercial websites became victims of Malvertising attacks. DOROS HADJIZENONOS, Country Manager of Check Point South Africa explains.

One of the most prominent ways malware spreads is by infecting websites and delivering drive-by attacks. When a user visits an infected site an exploit kit is activated. Once activated, the kit checks to see if the machine is vulnerable to one or more of the exploits it contains. If so, it leverages the vulnerability to install malicious software on the user’s device. Since this is a common threat, most websites harden their systems to protect themselves and their visitors from infection.

However, hackers can avoid the need to infect a well-guarded website by infecting the servers that supply advertisements to them instead. This form of attack is called Malvertising and is extremely effective for attackers who wish to reach a broad audience with their malware. The more popular the website, the larger the impact will be.

A Growing Trend

Malvertising is not a new form of an attack, but it has become headline news after several recent occurrences. At the beginning of March, a large Malvertising campaign targeting Baidu’s advertising platform was revealed. Despite having started in October 2015, this campaign’s evasive and elaborate nature enabled it to remain undercover and impact countless users in China for over four months. Two weeks later, several major news sites, including the BBC and New York Times, were hit with a Malvertising campaign. Visitors to these sites were targeted by a ransomware variant, similar to the infamous Cryptolocker attack, served by the Angler exploit kit. The attackers did not stop after the campaign was finally exposed.

They simply changed tactics to target videos as their Malvertising platform, instead of infecting users as they previously had through web banners. The campaign continued successfully targeting the Fox News website, among others.

Another recent Malvertising campaign targeted Australian users with an even more complex attack flow. First, they infiltrated a law firm’s website. Then they created fake advertisements containing the firm’s logo and published them on the Gumtree website, a subsidiary of eBay, which receives 48 million visitors a month. The attackers were able to stay hidden by altering the supplied ads, switching between benign and malicious ones, making it harder for security vendors to identify them.

Why Malvertising?

It is interesting to notice that hackers often attack suppliers who work with the main websites, rather than attacking the sites themselves. Often times, leveraging an attack through a supplier proves an easier path to success than a direct attack on the intended victim. We have seen this pattern with several Malvertising attacks. The same approach was used in the infamous Target hack, in which the attackers infiltrated Target’s network by compromising the network of Target’s suppliers first.

For this reason, we believe that the Malvertising trend will continue to impact major sites and users worldwide. In order to mitigate it, Ad servers must enhance their security measures and ensure the content they supply is legitimate.

How Can You Protect Your Organisation?

What we have learned from recent Malvertising attacks is that education and awareness about these threats are not enough to stay protected. Even the standard security measures that already exist in most organisations are only capable of preventing known threats and are not capable of countering the advanced, continuously evolving tactics of today’s cybercriminals.

Organisations that wish to stay fully protected must elevate their threat prevention strategies and protect themselves, not only from known threats, but also against unknown malware and zero-day threats, like Malvertising. To address this challenge, Check Point offers SandBlast Zero-Day Protection; the most advanced solution to protect against these new and unknown malware and advanced threats.

Mobile is the new branch

Standard Bank has launched an account for mobile devices that gives back 500MB of data a month

Standard Bank has introducd a R4.95p/m bank account called MyMo that customers can open on their mobile devices, loaded with data and airtime offerings and other benefits such as virtual and Gold physical card.

MyMo account holders will also enjoy the convenience of a cheque account through a Visa and Mastercard gold card. Once the account is open, users can choose to either receive R50 in airtime or 500MB of data a month, if their card is swiped more than four times a month. A further megabyte of data is loaded on the account for every R20 spent.

“MyMo is an account for everyone, whether you just landed your first job or have been around the block. With no documentation required it only takes a few minutes to open the account,” says Funeka Montjane, Chief Executive for Personal and Business Banking, South Africa, at Standard Bank Group. “For just R4.95 a month customer will be able to enjoy free swipes and ATM withdrawals at only R6.50 for amounts under R 1 000.

“Mobile is the new branch. This account is about bringing the mobile branch into customers hands, it is about convenience and security while banking.”

She says mobile offers low cost transactional banking which integrates people and businesses into the new connected economy, making mobile the new branch ecosystem that will drive and connect Africa’s growth. Physical connections to the economy are rapidly changing to digital where banks have to move from being financial institutions to service organisations.

“In the past people congregated in communities and eventually cities to maximise the advantages of connectivity. Today a simple hand-held device has the potential to open infinite doors, transforming individuals’ access to opportunities, regardless of where they are, and like never before in history. 

“Historically, a bank account represented access to economic citizenship. Today, having a simple device enabling digital access to a modern banking platform is a passport to global connectivity and vast human development potential.”

The bank says it is using technology, and mobile phones in particular, to deliver low-cost transactional channels accessible to all our customers. The evolution in mobile can be seen in transaction options like cash back at the retail checkout till rather than the ATM, free digital banking rather than using a branch, and the ability to transact using digital wallets, even without a bank account.

“Developing comprehensive connected ecosystems requires a mind-set change from Africa’s banks,” says Montjane. “Banks will evolve away from traditional financial service organisations, into service ecosystems enabling broad universal access to almost everything like enhanced purchasing experiences of vehicles and homes, online procurement of goods and services and lifestyle elements like rewards and travel. 

“These connectivity drivers will also act to future-proof evolving connectivity ecosystem by allowing us to offer untold future services while deriving income from as yet unrealised revenue streams,.   

From a customer perspective, the kind of ecosystems of knowledge, access and, ultimately, connectivity that banks will come to provide will radically transform the share of life that almost all individuals will be able to access.”

Two-thirds of SA staff hide social media from bosses

With 90% of people in employment going online several times a day, it can be hard for most workers to keep their private and work-life separate during the working day (and beyond). The recently published Global Privacy Report from Kaspersky Lab reveals that 64% of South African consumers choose to hide social media activity from their boss. This secretive stance at work also extends to their colleagues, with 60% of South Africans also preferring not to reveal online activities to their co-workers.

Globally, the average employee spends an astonishing 13 years and two months at work during their lifetime. Interestingly though, not all this time is directly related to solving work tasks or earning a promotion: almost two thirds (64%) of consumers admit visiting non-work-related websites every day from their desk.

Not surprisingly, 35% of South African employees are against their employer knowing which websites they visit. However, more interestingly, 60% of South African are even against their colleagues knowing about their online activities. This probably means that colleagues constitute an even greater threat to future perspectives of an office slouch or maybe the relationships with colleagues are more informal and therefore, more valuable.

On the contrary, social media activity appears to be a less private domain for many and therefore, more suitable for sharing with colleagues but not the boss. This is probably because workers fear harming the public image of a company or interest in decreased staff productivity motivates companies to monitor employees’ social networks and make career changing decisions based on that. Such policies have led to 64% of South Africans saying that they don’t want to reveal their social media activities to their boss and 53% even don’t want to disclose this information to their colleagues.

A further 29% are against showing the content of their messages and emails to their employer. In addition, 3% even said that their career was irrevocably damaged as a consequence of their personal information being leaked. Thus, people are worried about how to build a favourable internal reputation and how not to destroy existing workplace relationships.

“As going online is an integral part of our life nowadays, lines continue to blur between our digital existence at work and at home. And that’s neither good nor bad. That’s how we live in the digital age. Just keep remembering that as an employee you need to be increasingly cautious of what exactly you post on social media feeds or what websites you prefer using at work. One misconceived action on the internet could have an irrevocable long-term impact on even the most ambitious worker’s ability to climb the career ladder of their choice in the future,” comments Marina Titova, Head of Consumer Product Marketing at Kaspersky Lab.

To ensure workers don’t fall prey of the internet threats at a work, there are some core guidelines to adhere to in the digital age:

  • Don’t post anything that could be considered defamatory, obscene, proprietary or libellous. If in doubt, don’t post.
  • Be aware that system administrators may at least, in theory, be informed about your web browsing patterns.
  • Don’t harass, threaten, discriminate or disparage against any colleague, partner, competitor or customer. Neither on social networks or in messages, emails, nor by any other means.
  • Don’t post photographs of other employees, customers, vendors, suppliers or company products without prior written permission.
  • Start using Kaspersky Password Manager to ensure your social media and other personal accounts are not at risk of unauthorised access by someone else in an office. Install a reliable security solution such as Kaspersky Security Cloud to protect your personal devices.
