    The best place to hide a book is in a library. The most ideal place to hide a leaf is in the forest. And the best way to hide a suspicious email? In plain sight. Email security fraud is now so common that most internet users are now aware of basic hacker tricks, such as frequent misspellings and suspicious links. Yet even so,  phishing emails are a top point of entry for ransomware, making up 54 percent of digital vulnerabilities in 2020.  

    But what about the email security threats that aren’t as common? These types of threats can be even more successful because they aren’t as well known.  

    Here are six hidden threats of corporate email, some of which you may have heard or thought of and others perhaps you haven’t.  

    1.Unintentional acts by authorized users – Email security threats aren’t always intentional. Sometimes, they come from well-meaning corporate employees who simply make a mistake. Authorized users may accidentally send sensitive information via email to someone they trust (or who is acting as someone they trust), potentially exposing the organization to risk and potential brand reputation. That’s why it’s so important to train users on what types of information should and should not be shared through specific channels like email.  

    2.Improper Management Controls – Having properly defined management security controls is crucial for any organization. These controls could include company-wide security policies and processes, change control and configuration management, scheduled risk assessments, and contingency planning, and recurring annual or twice annual training for all employees, among other safeguards. Without these safeguards, employees are at risk of social engineering attacks like phishing, whaling, or ransomware.  

    3.Ransomware – Ransomware email messages contain or point to a common hacker tool: malware. This particular type of malware is designed to encrypt files and documents. Once they are encrypted, ransomware attackers contact the affected individual and  demand payment for recovery for their locked information. Ransomware may be less common than other social engineering attacks, but it can have hefty consequences. It is never advisable to pay for ransomware. Instead, work with law enforcement and cybersecurity experts.  

    4.Authentication Attacks – Sometimes, a hacker’s target is the email inbox itself. During authentication attacks, hackers attempt to break an email server’s authentication and gain access directly to email messages and attachments stored in that server. They then have access to do with that information what they will. That’s why it’s important to ensure your authentication methods are rock-solid. 

    5.Whaling – You’ve probably heard about phishing, a type of social engineering in which hackers pretend to be from reputable companies so that they can encourage unsuspecting victims to give up personal or sensitive corporate information. But have you heard of “whaling?” While hackers may not be choosy about who they target, scammers who ”whale” set their sights higher, targeting high-level executives in corporate organizations. And, they do their research. Whaling often relies on publicly-available information like that available on social media profiles to build credibility with the target. See our recent blog for more details on how to combat this common threat. 

    6.DDoS and Bot Attacks – Email security can be a warzone. With malicious bot and DDoS attacks, hackers can use hijacked botnets to send huge amounts of emails to an organization with the goal of crashing the email server due to system overload. Typically, web servers come under attack for B2C (business-to-customer) organizations that generate eCommerce sales, whereas email server attacks are commonly run on email servers, as this is where sensitive corporate information regarding sales and other information changes hands. This is where spam filtering becomes increasingly important.  


    How account takeovers work

    Account takeover – the criminal use of compromised online accounts – has the potential to be immensely profitable. Hackers steal credentials from individuals (see phishing) or target an entire organization using bots. They then use these stolen credentials to take ownership of the compromised accounts or sell credentials lists to other cybercriminals.

    Whoever uses the list can then impersonate users to steal funds or data, install malware or ransomware, or simply cause havoc through malicious acts. This can often happen within hours of the data breach taking place.

    In May 2022, the FBI issued an alert that they had “observed incidents of stolen higher education credential information posted on publicly accessible online forums or listed for sale on criminal marketplaces”.

    Originally, botnets were used to deliver massive volumes of spam, and responsible for 90% of the malware spread by email worldwide. Most of the biggest spam-sending botnets have been taken down, with Necrus botnet being the last, defeated by Microsoft in 2020.

    Since then, botnets have evolved, and are now being used to dispatch credentials to gain control of legitimate accounts, leading to a rapid escalation in the number and value of ATO attacks taking place each year.

    Every organization is at risk

    As well as opening the door to fraudulent financial transactions, it can enable cybercriminals to conduct more phishing attacks on more target individuals, departments, and organizations – not just ecommerce and financial businesses, but also healthcare, government agencies, and academic institutions.

    Email can be particularly vulnerable to ATO

    Impostors know that sending a fraudulent email from a legitimate email account means that traditional anti-phishing software is unlikely to flag their activity as suspicious, and recipients are more likely to trust the sender and to do what they ask.

    Once cybercriminals have gained access to an account, they can change anything related to its use, such as security questions, passwords, and encryption settings. This complete takeover makes it impossible for the real owner to gain access and can even cast suspicion on them or cause reputational damage.

    Account takeover protection and prevention

    The speed and evolution of today’s attacks present significant challenges for all organizations. Unfortunately, some of the most commonly used techniques aren’t enough to stop ATO, but there are some best practices that you should follow to help reduce risk.

    • Adopt a strong password policy
      Many accounts are easy to crack because of old, weak, or repeated passwords. Use a password manager with strong passwords.
    • Check for compromised credentials
      Regularly check the credentials of new users against a breached credentials database.
    • Limit the number of login attempts
      Locking an account after a set number of login attempts, based on username, device, and IP address, can help prevent account takeover.
    • Set multi-factor authentication
      Use a multi-factor authentication (MFA) method, such as tokens, biometrics, SMS access code or mobile app.
    • Notify users of account changes
      Send your users a notification of any changes to their account, so they can quickly spot if their account has been compromised and altered by someone else.

    Introducing the Libraesva Adaptive Trust Engine

    People’s level of trust tends to be based on experience, building over time as meaningful interactions take place. Using a similar experience-based approach, Libraesva’s Adaptive Trust Engine uses AI and machine learning to recognize the usual communication patterns of your email users and recipients. It dynamically tracks and monitors transactions to measure trust and behaviors, and uses history to understand what’s normal activity for each account.

    The Adaptive Trust Engine is part of Libraesva’s Email Security Gateway solution. It swiftly spots deviations and anomalies to stop first-time senders from delivering malware to accounts within your organization. It also works on outgoing traffic, preventing impostors from sending out spam from a compromised mailbox. From a user perspective, it’s unobtrusive – running in the background and only sending alerts when needed.

  • Tips And Best Practices For Small Business Email Management

    One of my friends, Janet, is a classic example of why you need email management in your business. She constantly receives hundreds of emails at work. One day, she had an important client presentation in the afternoon. But the client sent her an email the previous night rescheduling the meeting to the early morning instead. By the time she got to work, she should’ve already started with her presentation.

    Unfortunately, her inbox was already full of office news messages and newsletters. So by the time she sorted through them and found the client’s email, it was already too late. Her company ended up losing a valuable client contract. She wouldn’t have been stuck in this situation if she had applied email management best practices.

    Janet’s situation might sound all too familiar. Perhaps you’ve had a similar blunder or watched a similar situation unfold with one of your employees. Either way, it’s damaging to your business. To help you avert this crisis in the future, I’ll take you through what email management is and how it can help your business. Lots of things to go over, so let’s get started, shall we?

  • Manually Creating Swap Partition

    Continuing from this articles…

    What happened to Swap….

    Creating Swap partition alone would not suffice that it would be used by the system; it has to be initialized and activated.

    To initialize:

    # mkswap /dev/sda5

    To activate:

    # swapon /dev/sda5

    When I recreated the partition I didn’t know about the above and this…

    New Swap partition’s UUID had to update in /etc/fstab

    How to get the UUID, run this command:

    # blkid | grep swap | awk '{print $2}'

    Echo out the UUID into /etc/fstab file  and use the same as the previous swap entry

    Mount the swap with this command:

    # mount -a

    Well that fixed the missing swap issue….

    The final issue to address ” Gave up waiting for suspend/resume device”  message at boot time

    Don’t take me as a genius here… the fixes for the issues are all obtained by googling…credit goes to the original solution posters.

    The solution given was to remove


    and then run

    update-initramfs -u

    Well… did the above but the system went into a hung state with heavy CPU usage after reboot.

    As I always do in such cases, force restart the system into safe mode and then rebooted in to normal state…. Viola… no issue or Errors. 

  • Re-Sizing Linux Storage

    Continuing from this article

    While testing out the file server services; the storage space soon filled up.

    That’s when I realised I had provisioned only 16GB of Storage most likely I thought I’m won’t doing anything else besides sftp testing.

    So how exactly I increased the Storage size… 

    There are couple of options in hand for me to do this.

    1. Add Additional virtual disk and mount it as a folder for the shares
    2. Expand the current virtual disk and partition the extra free space and mount it as a shared folder
    3. Expand the current virtual disk and repartition the disk so there is no need for additional mounts

    Since I was in experimenting mood, I opted for option 3.

    The process would like this or at least I thought so:

    • Expand virtual disk to 120GB
    • Delete the current partition and recreate it
    • Resize the volume to take up the full capacity of the disk.

    The actual process as I had to do additional procedures to correct some of the actions which didn’t go as expected:

    1. Expand virtual disk to 120 GB – > easy peasy.. 
    2. Delete the current partition and recreate it

    I wasn’t so sure if this would go well but who cares its my test system anyway…

    I used


    which is more user friendly.

    Deleted the primary, extended and linux swap partitions

    Then readded the partitions with larger Primary partition with 116GB space, next extended and swap partition.

    Paid particular attention to enable Boot on primary partition, before committing the changes.

    So far so good…. ran

    resize2fs /dev/sda1 

    hoping to see the new disk size.

    The command returned to say something like .. no changes found no changes made.

    Thought rebooting the system would show the increase in partition orrr break the system….

    The reboot happened but it took way longer to then usual. There were error messsages like “missing swap partition” and “Gave up waiting for suspend/resume device”

    Didn’t knew what it meant so proceeded to resize the volume and this time the volume expansion was successful and it showed the full volume size 

    Then checked up why swap was not in use… that’s when I found that couple on things must be done to fix it. 

    What happened to Swap….

    Creating Swap partition alone would not suffice that it would be used by the system; it has to be initialized and activated. Please read to this linked article on how to activate swap partition

  • Debian 11 on 128 MB RAM

    Coming from Win 3.1 days, I can’t fathom what the craze with modern operating systems gobbling GBs of RAM. Therefore I took it on myself to find which modern OS can smoothly run with the least amount of RAM. So I set out some parameter the OS should server, like it should have the complete networking stack with the latest security modules like network encryption and system utilities.

    The OS : Debian 11, the latest release, and the least RAM the installer allows is 128 MB.
    Function of the system: Secure File Transfer Server

    Read on the see the challenges I encountered with Text Mode setup and the arcane file partitioning process

    The Process

    I started the VM with 64MB ram; the installer aborts with insufficient RAM message 

    And I doubled the size to 128MB,  this time the installer came up with a different message: Warning message of Low ram and the minimum of 273 ram required to successfully complete the installation. It didn’t stop me from proceeding next…

    Low Memory install mode. 

    In this mode, the installer doesn’t load up all drivers/modules which would cater to larger hardware types; instead it prompts for hardware type to load. 

    I selected the following modules from the above options for my vm type:

    • Choose mirror
    • NIC modules
    • MBR
    • Parted
    • Partman -Auto

    When prompted for NIC selection, its impossible to go to the next with wrong NIC type. The installer verifies the selection first just like the good old days of installing linux/windows 95.

    Low RAM didn’t have much impact on the installation process, it completed only about couple of seconds slower than a VM with about 2GB RAM.


    Minute boot delay compared to standard with 2GB of RAM.

    It handled multiple sftp connections without dips in the transfer chart

    Tried both SFTP and SMB services, the os can manage these services pretty well.

    Transferring files via SMB files peak up to 800Mbs.

    So what a VM of 128MB gives you…

    •  File server catering to up 10 users
    • SSH based vpn 
    • SFTP server
    • Open VPN server
    debian on 128MB ram
    memory utilisation

    There you have, Debian 11 32bit running on 128 MB RAM and utilising half the resource while running idle.

  • Phishing Activities in 2022

    Phishing scams continue to plague the internet in 2022, more now than ever. This article explores the latest data and current trends and shows you how to avoid a phishing attack today.

    Cybercrime consultants have found over a million discrete phishing attacks perpetrated this year, which is up by 61% in the same time period in 2021.

    In a recent sophisticated phishing attack, customers of the Dutch bank MKB were targeted with a fake newsletter that purported to be from MKB.

    The newsletter asked customers to follow a link to find out more about how the bank was supporting customers through the pandemic. The link took victims to a phony authorization page that stole their Outlook login credentials.

    This is the kind of cybercrime that was on the rise in 2022.
