Cable theft crisis hits Telkom

Published

on

Telkom plans to ramp up its rollout of wireless and fibre technology to counter a massive increase in copper cable theft over the past year, as criminal syndicates become more sophisticated.

Telkom has revealed that 6000 incidents of copper cable theft have occurred across Telkom’s copper network in the past year, costing the company more than R200-million. The level of theft tracks the international price of copper, and the modus operandi of cable thieves continually becomes more sophisticated.

As a result, says Telkom, it is ramping up efforts to migrate customers to wireless and fibre technologies to tackle cable theft syndicates.

“Copper theft has become a more sophisticated crime over the past few years,” says Telkom’s Group Executive for Communication Jacqui O’Sullivan. “These criminals now target our manholes armed with customised heavy duty vehicles, allowing them to hitch the cable to the vehicle and drive out kilometres of cable, cutting off thousands of customers, in a single incident.

“We face a unique set of challenges when it comes to copper cable theft. For example, there are areas in the Western Cape where gang violence sometimes makes it dangerous for us to send technicians into the area to replace stolen cables. In many high-theft areas, cable is repeatedly stolen, sometimes within days after replacements or repairs.”

O’Sullivan says it is clear that the price of copper and its strong demand in international markets, are catalysts of this crime. Analysis indicates that increases in theft incidents approximately tracks the level of the copper price – usually with a two to three month lag.

“For a little over a decade Telkom has continuously recorded revenue losses due to the impact of this crime. The persistent breaks in connectivity affect not just individual households, but also schools, government buildings, and industries across the country, making this crime a national concern.”

O’Sullivan says that the Company continues to invest greatly in securing the network with armed response, cable alarming and collaborative efforts with the South African Police Service however, the vast nature of Telkom’s network makes fighting this crime, an extraordinarily tough.

For the 2015 financial year, Telkom has experienced over R200 million rand in losses – R100 million direct cable theft repair cost and an additional R107m was spend on security services.

“The cost of cable theft to Telkom is serious and it has a significant impact on thousands of customers each year,” says O’Sullivan. “To combat this, we are looking at migrating our customers in high copper theft hotspots onto new technology platforms, specifically those which are undesirable to criminals.”

So far, Telkom has migrated close to 4000 customers in cable theft hotspots to an alternative wireless product, known as Waya Waya, which does not rely on a copper network. The new product allows customers to retain their landline numbers while also benefiting from SMS functionality and a free device.

Earlier this year, Telkom launched SA’s biggest fibre trial in which DSL customers within Telkom’s fibre footprint are being given the opportunity to upgrade their copper-based connectivity to the more advanced fibre network, at no additional cost.

“Telkom is taking every step to ensure that our network is secure and, more importantly, that our customers receive a seamless network experience free of criminal interference,” says O’Sullivan.

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.
