5 new cyberthreats pop up every second, here’s how to protect yourself

The start of 2018 has seen a massive rise in cryptocurrency mining and cryptojacking attacks, along with steady numbers of familiar malware and ransomware attacks, according to a Wednesday report from McAfee. On average, five new threat samples arose every second of Q1 2018, with several notable campaigns demonstrating just how sophisticated hackers have become.

“There were new revelations this quarter concerning complex nation-state cyber-attack campaigns targeting users and enterprise systems worldwide,” Raj Samani, chief scientist at McAfee, said in a press release. “Bad actors demonstrated a remarkable level of technical agility and innovation in tools and tactics. Criminals continued to adopt cryptocurrency mining to easily monetize their criminal activity.”

Of particular note was the rapid expansion of cryptojacking and other cryptocurrency mining attacks, in which criminals hijack victim’s browsers or infect their systems to mine for cryptocurrencies like Bitcoin—often without their knowledge. Coin miner malware grew a whopping 629% this year, growing from about 400,000 total known samples in Q4 2017 to more than 2.9 million in Q1 2018.

The rapid growth suggests that cybercriminals are drawn to the ease of infecting a user’s system and collecting the payments themselves, without having to rely on another party to monetize their attack, the report said.

“Cybercriminals will gravitate to criminal activity that maximizes their profit,” Steve Grobman, CTO at McAfee, said in the release. “In recent quarters we have seen a shift to ransomware from data-theft, as ransomware is a more efficient crime. With the rise in value of cryptocurrencies, the market forces are driving criminals to crypto-jacking and the theft of cryptocurrency. Cybercrime is a business, and market forces will continue to shape where adversaries focus their efforts.”

However, cryptomining is far from the only cyberthreat that businesses need to keep on their radar and protect against. Here are five campaigns the report identified as wreaking major havoc in Q1.

1. Bitcoin-stealing campaigns

A cybercrime ring called Lazarus launched a sophisticated Bitcoin-stealing phishing campaign called HaoBao this year, targeting global financial institutions and Bitcoin users, the report found. The attack came via malicious email attachments to victims, which, when opened, would implant a tool that scanned for Bitcoin activity and established a connection for ongoing data gathering and cryptomining.

2. Gold Dragon attacks

In January, the Gold Dragon attack targeted organizers of the Pyeongchang Winter Olympics in South Korea. The fileless malware attack—executed via a malicious Microsoft Word attachment that contained a hidden PowerShell implant script—encrypted stolen data and sent it to the attackers.

3. GhostSecret and Bankshot attacks

The international cybercrime group known as Hidden Cobra is believed to be associated with Operation GhostSecret, an attack targeting the healthcare, finance, entertainment, and telecommunications sectors and stealing data. The latest variation of the attack, called Bankshot, uses an embedded Adobe Flash exploit to allow hackers to get into victims’ systems.

4. LNK exploits

The amount of malware that exploits LNK capabilities grew 59% from Q4 2017 to Q1 2018, the report found. Meanwhile, PowerShell attacks have slowed.

5. Gandcrab ransomware

Growth in new ransomware slowed by 32% in Q1. However, the Gandcrab strain infected some 50,000 systems in the first three weeks of the quarter alone, taking Locky’s place as the ransomware leader. Gandcrab uses advanced methodologies, such as requesting ransom payments through the Dash cryptocurrency rather than through Bitcoin, to extract more value from their targets.

Tips to protect your business

Despite the rise of new attack types, business leaders can take a number of steps to protect employees and data.

In terms of cryptojacking, the attack is blocked by default in the browser Opera. Mozilla’s Firefox 63, due out in October, will block the attacks as well. Users can also download the minerBlock extension for Chrome and Firefox, as noted by TechRepublic contributor James Sanders.

Businesses can avoid the impact of ransomware by backing up files every day, and by taking other preventative steps.

Employee education remains paramount to any cybersecurity policy. Top ways to train employees to avoid cyberattacks include offering customised examples of threats that are relevant to an employee’s department and role (and particularly what phishing attacks look like), running unscheduling simulations of typical attacks, providing training models that employees can complete at their convenience, and rewarding those who take the proper actions.

This New Web Standard Could Finally Kill the Password

Passwords are pretty archaic. Unfortunately, despite the best efforts of companies including Google, Apple, Facebook and others, no one has figured out a uniform standard that would make it possible to do away with them entirely. Until, perhaps, now.

A new credential system proposed by the W3C—the World Wide Web Consortium—could be what we need to kill off the password for good.

Per the w3c, the new Web Authentication specification details an “API enabling the creation and use of strong, attested, scoped, public key-based credentials by web applications, for the purpose of strongly authenticating users.” In other words, this would be a universal system that could offer unique encryption keys for each user that could be accessed securely across every site, all in your standard web browser.

But the big upgrade is that, instead of being limited to a regular password, the API would also support the use of fingerprint readers, cameras, and USB keys as a method of logging into your account. In fact, some potential use cases even include using the fingerprint reader on your phone to log into a website that you’re browsing on your laptop or desktop, which may not have its own fingerprint sensor.

While the new standard is currently listed as just a “Candidate Recomendation,” the feature is already in use as an experimental technology in FireFox, with other browsers including Chrome and Edge expected to test the Web Authentication API later this year.

The sad part so far is that, despite input and contribution from companies such as Google, Microsoft, PayPal, Mozilla, Qualcomm and others, it doesn’t seem like Apple is on board to help test or refine the tech. That’s a real shame, because even though wide-scale adoption is still a ways out, it would be nice if there was a secure, non-proprietary login platform that all the big tech companies could agree on.

This Phishing Attack is Almost Impossible to Detect On Chrome, Firefox and Opera

A Chinese infosec researcher has discovered a new “almost impossible to detect” phishing attack that can be used to trick even the most careful users on the Internet.

He warned, Hackers can use a known vulnerability in the Chrome, Firefox and Opera web browsers to display their fake domain names as the websites of legitimate services, like Apple, Google, or Amazon to steal login or financial credentials and other sensitive information from users.
