Ransomware Attacks Grew By 485% In 2020
Ransomware attacks increased by an astonishing 485% in 2020 compared to 2019, according to Bitdefender’s 2020 Consumer Threat Landscape Report, which highlighted the ways cyber criminals targeted the COVID-19 pandemic. Interestingly, nearly two-thirds (64%) of the ransomware attacks took place in the first two quarters of 2020.

Cyber Insurance Firm Suffers Sophisticated Ransomware Cyber Attack; Data Obtained May Help Hackers Better Target Firm’s Customers
One of the largest insurance firms in the US CNA Financial was reportedly hit by a “sophisticated cyber security attack” on March 21, 2021. The cyber attack disrupted the company’s employee and customer services for three days as the company shut down “out of an abundance of caution” to prevent further compromise.
Ransom Gangs Emailing Victim Customers For Leverage
Some of the top ransomware gangs are deploying a new pressure tactic to push more victim organisations into paying an extortion demand: Emailing the victim’s customers and partners directly, warning that their data will be leaked to the dark web unless they can convince the victim firm to pay up.

'We Have Your Porn Collection': The Rise Of Extortionware
Experts say the trend towards ransoming sensitive private information could affect companies not just operationally but through reputation damage. It comes as hackers bragged after discovering an IT Director's secret porn collection. The targeted US firm has not publicly acknowledged that it was hacked. In its darknet blog post about the hack last month, the cyber-criminal gang named the IT director whose work computer allegedly contained the files.

Should Firms Be More Worried About Firmware Cyber Attacks?
Microsoft recently put out a report claiming that businesses globally are neglecting a key aspect of their cyber security - the need to protect computers, servers, and other devices from firmware attacks. Its survey of 1,000 cyber security decision makers at enterprises across multiple industries in the UK, US, Germany, Japan, and China has revealed that 80% of firms have experienced at least one firmware attack in the past two years. Yet only 29% of security budgets have been allocated to protect firmware.

Armed Conflict Draws Closer As State-Backed Cyber Attacks Intensify
The world is coming perilously close to nation states retaliating against cyber attacks with conventional weapons, according to a new HP report. Publicly available reports into state-sponsored attacks and interviews with scores of experts. It claimed there has been a 100% increase in “significant” state-backed attacks between 2017-20, and an average of over 10 publicly attributed attacks per month in 2020 alone.

Coca-Cola Trade Secret Theft Underscores Importance Of Insider Threat Early Detection
The trial of Xiaorong You started in Greenville, TN, this week. She is accused of trade secret theft and economic espionage after allegedly stealing technologies owned by several companies, including her former employers Coca-Cola and Eastman Chemical Company. The value placed on the development of the stolen technologies is $119.6 million. Other affected companies include Azko-Nobel, Dow Chemical, PPG, TSI, Sherwin Williams and ToyoChem.
The details of the case suggest that the damages the accused is allegedly responsible for could have been minimized if better real-time insider threat detection methods had been in place. They also outline possible motives for the theft of the intellectual property: ego and money.
Attackers Blowing Up Discord, Slack With Malware
Workflow and collaboration tools like Slack and Discord have been infiltrated by threat actors, who are abusing their legitimate functions to evade security and deliver info-stealers, remote-access trojans (RATs) and other malware. The pandemic-induced shift to remote work drove business processes onto these collaboration platforms in 2020, and predictably, 2021 has ushered in a new level cyber criminal expertise in attacking them.

Scraped Data Of 500 Million LinkedIn Users Being Sold Online, 2 Million Records Leaked As Proof
An archive containing data purportedly scraped from 500 million LinkedIn profiles has been put for sale on a popular hacker forum, with another 2 million records leaked as a proof-of-concept sample by the post author. The four leaked files contain information about the LinkedIn users whose data has been allegedly scraped by the threat actor, including their full names, email addresses, phone numbers, workplace information, and more.
While users on the hacker forum can view the leaked samples for about $2 worth of forum credits, the threat actor appears to be auctioning the much-larger 500 million user database for at least a 4-digit sum, presumably in bitcoin.
Massive Facebook Data Breach Leaks Info On Millions Of Users
The personal information of hundreds of millions of Facebook users across the globe has been leaked online. Around 533 million Facebook users are thought to have been affected by the data breach, with phone numbers, Facebook ID, full name, location, past location, birthdate, email address, account creation date, relationship status, and personal bios all available. The data is thought to be the same set that was leaked in January 2021 and was available to purchase online, meaning Facebook has failed to secure its users once again.
