Cybercriminals are selling access to OTP code-generating company servers

Cybersecurity specialists report that a hacker is selling real-time access to a single-use password system, allowing cybercriminals to access Facebook, Twitter, Google, Amazon, Microsoft, Signal, Telegram accounts, among many others without having to obtain multi-factor authentication codes.

This report should be taken seriously, as a related attack could engage billions of users. In turn, cybersecurity experts point out that this is the consequence of using servers that handle OTP requests from online service users.

The first reports on this hacker were published by researcher Rajshekhar Rajaharia, who mentions that the hacker offers 50 GB of data extracted from multiple sources and webshell access to the OTP generating platform. The seller asks for about $5000 USD in cryptocurrency, although Rajaharia notes that initially the hacker planned to sell this information for about $18000 USD.

Malware Variants: More Sophisticated, Prevalent and Evolving in 2021

Employees play a vital role in ensuring their company’s cybersecurity bubble remains intact. Many malware campaigns begin by sending an e-mail communication to employees. To learn basic cybersecurity hygiene, employees must become familiar with password management, identify and report security threats, and recognize suspicious behavior. Regular content and training will assist employees in countering any malware threats they encounter.

Adopt a culture of comprehensive security.

Given the ongoing evolution of malware attacks and their capability to surpass what they were capable of, organizations should prioritize a strong malware protection strategy. Consultation with experienced cybersecurity experts like Indusface can help them create a solution that meets their needs.

1-Click Hack Found in Popular Desktop Apps — Check If You’re Using Them

Multiple one-click vulnerabilities have been discovered across a variety of popular software applications, allowing an attacker to potentially execute arbitrary code on target systems.

The issues were discovered by Positive Security researchers Fabian Bräunlein and Lukas Euler and affect apps like Telegram, Nextcloud, VLC, LibreOffice, OpenOffice, Bitcoin/Dogecoin Wallets, Wireshark, and Mumble.

“Desktop applications which pass user supplied URLs to be opened by the operating system are frequently vulnerable to code execution with user interaction,” the researchers said. “Code execution can be achieved either when a URL pointing to a malicious executable (.desktop,.jar,.exe, …) hosted on an internet accessible file share (nfs, webdav, smb, …) is opened, or an additional vulnerability in the opened application’s URI handler is exploited.”

Thousands of devices infected with the SolarMarket Trojan via malicious websites

A recent report notes that a hacking group is employing search engine optimization (SEO) tactics to trick users into attracting them to over 100000 legitimate-looking malicious websites through the Google browser.

The goal of this campaign is to install a Remote Access Trojan (RAT) on vulnerable devices, which would allow the deployment of subsequent attacks and infections. The eSentire signature experts detected this campaign, mentioning that malicious web pages appear in browser results when the user searches for terms related to invoices, receipts, questionnaires and resume.

Hackers use search redirection and direct download methods to redirect users to Trojan download sites identified as SolarMarket (also known as Jupyter, Yellow Cockatoo or Polazert). Users who visit a compromised website are infected almost immediately after entering these pages via a malicious PDF file.

The FBI is remotely hacking hundreds of computers to protect them from Hafnium

With full court approval.

In what’s believed to be an unprecedented move, the FBI is trying to protect hundreds of computers infected by the Hafnium hack by hacking them itself, using the original hackers’ own tools (via TechCrunch).

The hack, which affected tens of thousands of Microsoft Exchange Server customers around the world and triggered a “whole of government response” from the White House, reportedly left a number of backdoors that could let any number of hackers right into those systems again. Now, the FBI has taken advantage of this by using those same web shells / backdoors to remotely delete themselves, an operation that the agency is calling a success.

“The FBI conducted the removal by issuing a command through the web shell to the server, which was designed to cause the server to delete only the web shell (identified by its unique file path),” explains the US Justice Department.

Preparing for AI-enabled cyberattacks

MIT Technology Review Insights, in association with AI cybersecurity company Darktrace, surveyed more than 300 C-level executives, directors, and managers worldwide to understand how they’re addressing the cyberthreats they’re up against—and how to use AI to help fight against them.

Cyberattacks continue to grow in prevalence and sophistication. With the ability to disrupt business operations, wipe out critical data, and cause reputational damage, they pose an existential threat to businesses, critical services, and infrastructure. Today’s new wave of attacks is outsmarting and outpacing humans, and even starting to incorporate artificial intelligence (AI). What’s known as “offensive AI” will enable cybercriminals to direct targeted attacks at unprecedented speed and scale while flying under the radar of traditional, rule-based detection tools.

Some of the world’s largest and most trusted organizations have already fallen victim to damaging cyberattacks, undermining their ability to safeguard critical data. With offensive AI on the horizon, organizations need to adopt new defenses to fight back: the battle of algorithms has begun.

3 Key Cybersecurity Trends To Know For 2021 (and On …)

3 Key Cybersecurity Trends To Know For 2021 (and on…)

Other mitigation efforts can be done by employing new technologies that monitor, alert, and analyze activities in the network. Emerging technologies such as artificial intelligence and machine learning tools can help provide visibility and predictive analytics. It is also good to have diversification and multiple sourcing for suppliers in the event of a breach. Preparation and redundancy are advantageous in crisis scenarios. But like most issues in cybersecurity, it comes down to people, vigilant processes, and technologies coupled with risk factors constantly being reviewed.

Of course, there are many other compelling trends and threats to the cybersecurity ecosystem. More to cover in future articles. I have highlighted the more immediate trends of the expanding cyber-attack surface remote work, IoT supply chain, ransomware as a cyber weapon of choice and threats to critical infrastructure via ICS, OT/IT cyber-threat convergence. The most important tasks based on analyzing trends is to be have a mitigation strategy, be vigilant, try to fill gaps, and learn from lessons of the recent cyber-breaches.

Google Warns of Zero-Click Bluetooth Flaws in Linux-based Devices

Google security researchers are warning of a new set of zero-click vulnerabilities in the Linux Bluetooth software stack that can allow a nearby unauthenticated, remote attacker to execute arbitrary code with kernel privileges on vulnerable devices.

According to security engineer Andy Nguyen, the three flaws — collectively called BleedingTooth — reside in the open-source BlueZ protocol stack that offers support for many of the core Bluetooth layers and protocols for Linux-based systems such as laptops and IoT devices.

The first and the most severe is a heap-based type confusion (CVE-2020–12351, CVSS score 8.3) affecting Linux kernel 4.8 and higher and is present in the Logical Link Control and Adaptation Protocol (L2CAP) of the Bluetooth standard, which provides multiplexing of data between different higher layer protocols.

New ‘Silver Sparrow’ Malware Infected Nearly 30,000 Apple Macs

Days after the first malware targeting Apple M1 chips was discovered in the wild, researchers have disclosed yet another previously undetected piece of malicious software that was found in about 30000 Macs running Intel x86_64 and the iPhone maker’s M1 processors.

However, the ultimate goal of the operation remains something of a conundrum, what with the lack of a next-stage or final payload leaving researchers unsure of its distribution timeline and whether the threat is just under active development.

Calling the malware “Silver Sparrow,” cybersecurity firm Red Canary said it identified two different versions of the malware — one compiled only for Intel x86_64 and uploaded to VirusTotal on August 31, 2020 (version 1), and a second variant submitted to the database on January 22 that’s compatible with both Intel x86_64 and M1 ARM64 architectures (version 2).
