The Top Five Cybersecurity Vulnerabilities for Businesses

Published

on

Cyber crime is the biggest threat that any major financial or governmental organization face in today’s world. This form of crime is not physical, but ramifications of it are far more severe and ghastly than  conventional crime. Where physical attacks are threatening to loss of life of personnel, cyber crimes can put entire economies at risk, wipe out the bank accounts, expose the biggest secrets of any nation, and more.

The attackers may be located hundreds of miles away from the site of the attack. Government agencies all over the world are fighting hard in the battle against cyber crimes. It is not just the big guns that are at risk, though. Small business owners, as well as everyday users, are constantly at risk of being attacked by cyber criminals.

As this is one of the biggest threats we face in today’s world where almost everything is either already computerized or is on the brink of being computerized, one needs to be aware of the most common cybersecurity vulnerabilities.

Below are the top five cybersecurity vulnerabilities for businesses:

1. Sensitive Data Exposure

This is one of the most primary areas that hackers (or insiders) target. They snoop around inside a big corporation’s network and then steal, damage, or expose some of the most sensitive data like financial statements, company policies, different databases, and customer information which can cause major problems for the targeted organization.

2. Buffer Overflow

If the attacker has knowledge of the buffer management and space allocation system of the target machine, then he can send a code with malicious data. The data would be bigger for the size allocated to the application that runs it, causing the application to use more than its allocated buffers. When control reverts back to the hacker, he can overwrite or damage the adjacent buffer blocks.

The attackers basically send an application on the user’s system a code, requiring it to store some data by allocating space in the buffer. Now, the attacker knows that the data the app would be storing requires extra buffer space than it will be allocated, so the app running his code will use more buffer blocks than it was supposed to. On completion, it returns the pointer to the location it stored the data in. This will be different than it was because it took up further buffer blocks than it was allocated. This information is sent back to the hacker, who can use the knowledge to manipulate data in the buffer address pointed at by the returning code. You can read more about it here.

3. Injection Vulnerabilities

Injection Vulnerabilities occur whenever a client sends untrusted data to an interpreter. Applications like XML parsers and program arguments as well as SQL can easily be victimized using this cybe-security vulnerability. Sensitive data can easily be compromised once injection vulnerabilities are exploited. Despite being relatively easy to detect and prevent, attackers who target this vulnerability are successful quite regularly.

4. Broken Authentication or Session Management

This is also a common cybersecurity vulnerability. Data, when unencrypted, is vulnerable to theft when it is exchanged over an internet session. The cyber criminals specifically target weak areas in the authentication and session management that is done between any two systems for exchange of packets. Using techniques like the Man-in-the-Middle attack, an attacker can intercept and decipher the data sent by a user if it is encrypted poorly. The attacker can then masquerade as the user, exploiting all the privileges granted to the user to manipulate the other system into disclosing more information that the attacker could mishandle.

5. Security Misconfiguration

These are small mistakes that the users make which can easily be taken advantage of by any hacker. Employees often use default passwords for security systems, or run some outdated software, or even run some unnecessary applications on their systems. All these are simple targets for any attacker that has some basic knowledge about hacking.

End Note

This article looks at the top five cybersecurity vulnerabilities for businesses. However, there are more than just these five, and it is vital that you be aware of them in order to safeguard yourself as well as your system from being victimized by notorious attacks.

Monero Price Analysis: Stronger Malware to Mine Monero; XMR/USD Has Room for Another Potential Squeeze South

Published

on

  • Researchers: a stronger malware has been uncovered, which can mine Monero.
  • XMR/USD price action remains stuck in a narrowing range, subject to an imminent breakout.

The XMR/USD price has seen some upside on Saturday, holding gains of around 3% towards the latter stages of the day. Despite the press higher from the bulls, a move which has been observed across the cryptocurrency market, vulnerabilities remain. Price action has been ranging for the past nine sessions. Once again, this isn’t specifically just XMR, as this type of behavior is witnessed across the board. The narrowing in play came after the steep drop that rippled across the market on 10th January.

Price action was initially well-supported to the upside by an ascending trend line, which was in play from 15th December. This at the time was a very promising recovery, as XMR/USD had gained as much as 55%. Unfortunately, however, the bulls were unable to break down supply heading into the $60 region and were eventually dealt a big hammer blow. On 10th January, the market bears forced a heavy breach to the downside, smashing through this support. The price had dropped a big double-digits, some 20%.

Stronger Malware Mining Monero (XMR)

There is a dangerous form of malware that can bypass being detected and mine Monero (XMR) on cloud-based servers. A recent notice was put out by Palo Alto Networks’ Unit 42, an intelligence team that specializes in cyber threats, regarding a Linux mining malware. This was detailed to have been developed by Rocke group, which has the ability uninstall cloud security products. It can do this to the likes of Alibaba Cloud and Tencent Cloud, to then illegally mine Monero on compromised machines.

The two researchers from Palo Alto Networks, Xingyu Jin and Claud Xiao, detailed the findings of their studies. Once the malware is downloaded, it takes administrative control to initially uninstall all cloud security products. Shortly after, it will then then transmit code that will mine the Monero (XMR). Further within their press release, they said, “To the best of our knowledge, this is the first malware family that developed the unique capability to target and remove cloud security products.”

Technical Review – XMR/USD

XMR/USD daily chart.

Given the current range block formation, eyes should be on the key near-term technical areas. Firstly, to the downside, $43, which is the lower part of the range. A breach here will likely see a retest of the December low, $38. To the upside, resistance be observed at around the mid $46 level. Should a breakout be observed here, then a potential retest of the broken trend line will be watched.

Dash 51% Attack Fears Cooled as Core Dev Group Suggest Benevolent Miner

Published

on

Dash investors may have been starting to question the security of their holdings in light of Ethereum Classic’s (ETC) recent attack, and the subsequent fallout which revealed Dash’s own vulnerability to 51% attacks.

Three addresses, all controlled by the same user, were in control of more than 51% of the Dash mining hashrate, as reported on CCN a few days ago. On top of that, over 74% of the entire Dash hashrate was accessible via Nicehash – a cloud-mining marketplace – where it could be purchased for as little as $3,104 per hour.

Hashing Power Removed from Nicehash

As of Saturday’s statement by the Dash Core Group, the same individual still controls the majority of the Dash hashrate. However, the group pointed out that since the news concerning a 51% attack broke out earlier this week, the individual has begun to remove their hashing power from Nicehash, and spread it around separate mining pools.

The team stated clearly that they do not believe the miner in question to be malicious:

“…we don’t believe the entity in control of the wallets in question plans or wants to attack because their mining activities began at least 4 months ago and their blocks have been published for all to see.”

The group believe the sudden removal of hashing power from Nicehash – as shown above – is a signal of benevolent intentions on the part of the miner. As a major holder of Dash, they reason that the miner would want to secure the network as best they could.

“This removes the risk of a malicious party renting the hashing power via NiceHash and simultaneously signals that the entity in control of the hashing power does not have negative intent. We believe the miner behind the hashing power was made aware by the same info we discovered online and quickly moved to more protected pools as they appear to be a major stakeholder of Dash.”

Future Proof?

The announcement ends with a look to the future in the form of Dash’s upcoming ChainLocks technology. To be implemented in an as yet unspecified future update, ChainLocks will unite the mining layer with that of the Dash’s masternodes.

This means that a 51% attacker would also have to secure a majority of the blockchain’s masternodes to execute their plans. More can be read on ChainLocks here.

Dash Coin Price

Almost mid-way through the first month of 2019, Dash has recovered 26% of its value since the market lows of mid-December. That’s when one unit of DASH was valued at $58.27 – a 96% decline since December 2017.

Dash’s 26% recovery in the past month still leaves the coin 95% off its all-time high. As of Saturday the coin had settled down along with the broader market, after a sharp 17.5% decline 48 hours before.

Where to Store Your Crypto?

Published

on

By

Storing crypto on virtual exchanges has some inherent security risks that have been exploited by hackers and cyber criminals. This article will touch upon this important topic and provide you with alternative methods in which to store your digital assets.

Cold and Hot Wallets

The main thing in cryptocurrency storage is the private key and who has access to it.

Cold storage wallets operate offline and without a constant internet connection. If your key is not on the Internet, then it is much more difficult to steal.

A hot storage wallet is a wallet with constant connection to the Internet.

So, all storage options can be distinguished by the following criteria:

  1. private keys are kept by you or by third parties.
  2. without internet connection or with internet connection

A cold storage wallet with a private key is considered the most reliable storage option. Such a wallet is suitable for long-term storage of large amounts. However, it is not convenient if, for example, you do trading and need access to your wallet for transferring small amounts.

Hardware Wallets

hardware wallets like Ledger, Trezor, Pi Wallet, Keepkey, Opendime, Bitlox, etc. have a flash drive within the software without an internet connection. You can connect to the Internet only when sending a transaction. You need to confirm the transaction physically, from the device itself. This is a “cold” method of storage without an internet connection (connection only at the time of the transaction). The user keeps private keys.

Paper Wallets

This method of storage will be also convenient for you if you want to conserve your funds for an extended period. In offline mode, you can generate a public and private key. For example, if you are using the service walletgenerator.net it will transfer those keys in the form of a QR-code, which can be printed and stored by you.

Physical Bitcoin Wallet

A physical bitcoin wallet has almost the same properties as a paper wallet. Encrypted bitcoins cannot be spent until the seal protecting the secret key has been broken. However, the security of the seal is not considered very reliable.

Desktop Offline Wallets.

There are also two main types of offline wallets:

  1. Wallets, where the user is the only one with the access to private keys. You can install such wallets on a personal computer as a separate program. As a rule, these are the wallets from the developers of that cryptocurrency. For example, Bitcoin Core. Litecoin Core, Mist, etc. Such wallets are also called “heavy” wallets since during installation they take up quite a lot of space (for example, you will have to free up at least 200 GB for a Bitcoin wallet in 2018). When installing such wallets on laptops flash drives that are disconnected from the Internet can also be called “cold” wallets. In general, they are also considered safe.
  2. The so-called “light” offline wallets. These are desktop wallets that allow you to store cryptocurrency without downloading its full registry to a bunch of gigabytes. Some of them give you private keys and the ability to restore a lost wallet at any time using seed phrases. There is a drawback – they do not always contain the full version of the blockchain, and sometimes won’t show up-to-date transaction information. Examples of such a wallet are Electrum and Armory.

Light wallets can be multi-currency, with a built-in internal exchange for example Exodus. Its private keys can also be restored using seed-phrases. However, inside such wallets, not only you but also developers have access to your private keys.

It is also worth to mention an essential aspect of light wallets, which are open source code. If something happens to the wallet, then it will be only possible to restore the wallet using the seed phrase only if the function is restored.

As a conclusion on cold wallets, I can say that their main advantage is reliability and security, and the main drawback is that it is difficult to move cryptocurrencies quickly. Therefore, cold wallets are suitable for long-term storage. For everyday transactions, hot wallets are the best. The exceptions are some hardware wallets that are compatible with online cryptocurrency storage and exchange services.
