‘Grey Saturday’ safer for shopping

Published

on

The annual Black Friday/Cyber Monday sales offer incredible opportunities, but they are also peak days for financial phishing attacks – and consumers are significantly safer on ‘Grey Saturday’, when the number of such attacks drops by up to a third.

Kaspersky Lab’s review found signs of Grey Saturday attack dips in both 2016 and 2015. In 2016 there was a decline of 33 percent in the number of attacks using popular online retail and payment brands (from around 770,000 to 510,000 detections), despite it being the second biggest shopping day in some countries, such as the U.S.

It represents a rare moment of respite from the cybercriminals in an ever busier holiday shopping season that now runs from October through December. Traditionally distributed by email, phishing attacks now also lure consumers through weblinks, banners, social media and more, persuading them to part with their personal financial data in the belief they are dealing with a reputable, known brand.

“The rise in people using online payments, banking and shopping means that financial phishing attacks are now consistently high all year round, but the holiday season makes it so much easier to hide in the noise. At this time of year, marketing and advertising levels go through the roof, and with consumers increasingly making their transactions on mobiles – probably while out and about and in a hurry – almost everyone is more exposed and has less time to think and check. On Grey Saturday the number of attacks drop significantly. Weekends generally see lower numbers of attacks and fewer people online – but on this big shopping day that’s an extra advantage. We expect this trend from 2016 to continue in 2017, so if you plan on shopping online these holidays, choose the day wisely,” said Nadezhda Demidova, Lead Web-Content Analyst, Kaspersky Lab.

Other findings of the report include:

  • Following a decline in 2015, financial phishing abusing online payment systems, banks and retailers increased again in 2016.
  • Financial phishing now accounts for half (49.77 per cent) of all phishing attacks, up from 34.33 per cent in 2015.
  • Mobile-first consumers are likely to be a key driver behind the rise in financial phishing: the use of smartphones for online banking, payment and shopping has doubled in the last year according to the 2017 Kaspersky Cybersecurity Index.
  • Financial phishers are exploiting the Black Friday name in their attacks, as well as consumer awareness of, and concerns about online security – disguising their attack messages as security alerts, implications that the user has been hacked, or adding reassuring-sounding security messages.

In order to stay protected while shopping online – on any day – Kaspersky Lab offers the following advice:

  • Do not click on any links received from unknown sources or on any links that look suspicious.
  • Do not use insecure public Wi-Fi networks to make online payments, as hotspots can easily be hacked in order to listen to user traffic and steal confidential information.
  • Do not enter your credit card details on unfamiliar or suspicious sites and always double-check the webpage is genuine before entering any personal information (at least take a look at the URL). Fake websites may look just like the real ones.
  • Only use sites which run with a secure connection – the address of the site should begin with HTTPS://.
  • The more information is being asked for, the more cautious you should be: ask yourself if they really need all the information they demand.
  • Remember that banks and payment companies will never ask you to enter all your credentials.  If in doubt, call them.
  • Install a security solution on your device with built-in technologies designed to prevent financial fraud. For example, Safe Money technology in Kaspersky Lab’s solutions creates a secure environment for financial transactions on all levels.

Kaspersky Lab’s holiday season financial phishing overview is based on information gathered by Kaspersky Lab’s heuristic anti-phishing component that activates every time a user tries to open a phishing link that has not yet been added to Kaspersky Lab’s database.

To assist users seeking for a reliable security solution, Kaspersky Lab is running a special offer. Anyone who purchases Kaspersky Internet Security or Kaspersky Total Security for 1, 3 or 5 devices, will get 50% discount for online purchases. The promotion will run from the 22nd – 30th of November. For more information, please visit: https://www.kaspersky.co.za/home-security#all

Cons exploit Telegram ICO

Published

on

Kaspersky Lab researchers have uncovered dozens of highly convincing fake websites claiming to be investment sites for an initial coin offering (ICO) by the Telegram messaging service. Many of these websites appear to belong to the same group. In one case alone, tens of thousands of US dollars’ worth of cryptocurrency were stolen from victims believing they were investing in ‘Grams’, Telegram’s rumoured new currency. Telegram has not officially confirmed an ICO and has warned people about fraudulent investor sites.

In late 2017, stories started to circulate that the Telegram messaging service was launching an initial coin offering (ICO) to finance a blockchain platform based on its TON (Telegram Open Network) technology. Unverified technical documentation was posted online, but there appears to have been no confirmation from Telegram itself. The resulting confusion seems to have allowed fraudsters to capitalise on investor interest by creating fake sites and stealing vast sums of money.

Kaspersky Lab researchers have discovered dozens of such sites, possibly belonging to the same group, claiming to sell tokens for ‘Grams’ and inviting investors to pay with cryptocurrencies including Bitcoin, Ethereum, lice litecoin, dash and Bitcoin dash. A record of transactions on one site revealed that the scammers were able to steal at least $35,000 US dollars’ worth of Ethereum from investors.

The researchers found that some of the websites were so convincing that even after Telegram and others began to issue warnings, they were still able to recruit potential investors. Most use a secure connection, require registration and generate a unique online wallet for each new victim, making it harder to track the money.

Judging by the content of the fake websites, it appears they may have common ownership. For example, several have the exactly the same ‘Our Team’ section.

“ICOs are a fairly risky investment and many people don’t yet fully understand how they work, so it is not surprising that high quality fake websites, with seemingly reassuring features such as a secure connection and registration are successful at luring people in. People wishing to invest in an ICO would do well to check with the company behind it and make sure they know exactly who they are giving their money to, or they may never see it again,” said Nadezhda Demidova, Lead Web-Content Analyst, Kaspersky Lab.

Kaspersky Lab offers the following advice for users considering investing in an ICO:

  • Check for warning signs: for example, some of the fake Telegram ICO websites had the same wrong image next to the name of Telegram’s Chief Product Officer.
  • Do your homework: always check with the brand’s official site to verify the legitimacy of the investment site and, if necessary contact the company’s ICO teams before investing any money or currency.
  • Use reliable security solutions such as Kaspersky Internet Security and Kaspersky Internet Security for Android, which will warn you if you try to visit fake internet pages.

Crouching Yeti strikes

Published

on

Kaspersky Lab has uncovered infrastructure used by the Russian-speaking APT group Crouching Yeti, also known as Energetic Bear, which includes compromised servers across the world.

According to the research, numerous servers in different countries were hit since 2016, sometimes in order to gain access to other resources. Others, including those hosting Russian websites, were used as watering holes.

Crouching Yeti is a Russian-speaking advanced persistent threat (APT) group that Kaspersky Lab has been tracking since 2010. It is best known for targeting industrial sectors around the world, with a primary focus on energy facilities, for the main purpose of stealing valuable data from victim systems. One of the techniques the group has been widely using is through watering hole attacks: the attackers injected websites with a link redirecting visitors to a malicious server.

Recently Kaspersky Lab has discovered a number of servers, compromised by the group, belonging to different organisations based in Russia, the U.S., Turkey and European countries, and not limited to industrial companies. According to researchers, they were hit in 2016 and 2017 with different purposes. Thus, besides watering hole, in some cases they were used as intermediaries to conduct attacks on other resources.

In the process of analysing infected servers, researchers identified numerous websites and servers used by organisations in Russia, U.S., Europe, Asia and Latin America that the attackers had scanned with various tools, possibly to find a server that could be used to establish a foothold for hosting the attackers’ tools and to subsequently develop an attack. Some of the sites scanned may have been of interest to the attackers as candidates for waterhole. The range of websites and servers that captured the attention of the intruders is extensive. Kaspersky Lab researchers found that the attackers had scanned numerous websites of different types, including online stores and services, public organisations, NGOs, manufacturing, etc.

Also, experts found that the group used publicly available malicious tools, designed for analyzing servers, and for seeking out and collecting information. In addition, a modified sshd file with a preinstalled backdoor was discovered. This was used to replace the original file and could be authorised with a ‘master password’.

“Crouching Yeti is a notorious Russian-speaking group that has been active for many years and is still successfully targeting industrial organisations through watering hole attacks, among other techniques. Our findings show that the group compromised servers not only for establishing watering holes, but also for further scanning, and they actively used open-sourced tools that made it much harder to identify them afterwards,” said Vladimir Dashchenko, Head of Vulnerability Research Group at Kaspersky Lab ICS CERT.

“The group’s activities, such as initial data collection, the theft of authentication data, and the scanning of resources, are used to launch further attacks. The diversity of infected servers and scanned resources suggests the group may operate in the interests of the third parties,” he added.

Kaspersky Lab recommends that organisations implement a comprehensive framework against advanced threats comprising of dedicated security solutions for targeted attack detection and incident response, along with expert services and threat intelligence. As a part of Kaspersky Threat Management and Defense, our anti-targeted attack platform detects an attack at early stages by analysing suspicious network activity, while Kaspersky EDR brings improved endpoint visibility, investigation capabilities and response automation. These are enhanced with global threat intelligence and Kaspersky Lab’s expert services with specialisation in threat hunting and incident response.

More details on this recent Crouching Yeti activity can be found on the Kaspersky Lab ICS CERT website.
