As the digital age evolves and continues to shape the business landscape, corporate networks have become increasingly complex and distributed. The amount of data a company collects to detect malicious behaviour constantly increases, making it challenging to detect deceptive and unknown attack patterns and the so-called "needle in the haystack". With a growing number of cybersecurity threats, such as data breaches, ransomware attacks, and malicious insiders, organizations are facing significant challenges in successfully monitoring and securing their networks. Furthermore, the talent shortage in the field of cybersecurity makes manual threat hunting and log correlation a cumbersome and difficult task. To address these challenges, organizations are turning to predictive analytics and Machine Learning (ML) driven network security solutions as essential tools for securing their networks against cyber threats and the unknown bad. The Role of ML-Driven Network Security Solutions ...

A new information stealer called  Stealc  that's being advertised on the dark web could emerge as a worthy competitor to other malware of its ilk. "The threat actor presents Stealc as a fully featured and ready-to-use stealer, whose development relied on  Vidar ,  Raccoon ,  Mars , and  RedLine  stealers," SEKOIA  said  in a Monday report. The French cybersecurity company said it  discovered   more than   40 Stealc samples  distributed in the wild and 35 active command-and-control (C2) servers, suggesting that the malware is already gaining traction among criminal groups. Stealc, first marketed by an actor named Plymouth on the XSS and BHF Russian-speaking underground forums on January 9, 2023, is written in C and comes with capabilities to steal data from web browsers, crypto wallets, email clients, and messaging apps. The malware-as-a-service (MaaS) also boasts of a "customizable" file grabber that allows its buyer...

Popular cryptocurrency exchange platform Coinbase disclosed that it experienced a cybersecurity attack that targeted its employees. The company  said  its "cyber controls prevented the attacker from gaining direct system access and prevented any loss of funds or compromise of customer information." The incident, which took place on February 5, 2023, resulted in the exposure of a "limited amount of data" from its directory, including employee names, e-mail addresses, and some phone numbers. As part of the attack, several employees were targeted in an SMS phishing campaign urging them to sign in to their company accounts to read an important message. One employee is said to have fallen for the scam, who entered their username and password in a fake login page set up by the threat actors to harvest the credentials. "After 'logging in,' the employee is prompted to disregard the message and thanked for complying," the company said. "What hap...

A spear-phishing campaign targeting Indian government entities aims to deploy an updated version of a backdoor called ReverseRAT . Cybersecurity firm ThreatMon  attributed  the activity to a threat actor tracked as  SideCopy . SideCopy is a threat group of Pakistani origin that shares overlaps with another actor called  Transparent Tribe . It is so named for mimicking the infection chains associated with  SideWinder  to deliver its own malware. The adversarial crew was first observed delivering ReverseRAT in 2021, when Lumen's Black Lotus Labs  detailed  a set of attacks targeting victims aligned with the government and power utility verticals in India and Afghanistan. Recent attack campaigns associated with SideCopy have primarily  set their sights  on a two-factor authentication solution known as Kavach (meaning "armor" in Hindi) that's used by Indian government officials. The infection journey documented by ThreatMon commences...

Norwegian police agency Økokrim has announced the seizure of 60 million NOK (about $5.84 million) worth of cryptocurrency stolen by the Lazarus Group in March 2022 following the Axie Infinity Ronin Bridge hack. "This case shows that we also have a great capacity to follow the money on the blockchain, even if the criminals use advanced methods," the Oslo-based crime-fighting unit  said  in a statement. The development comes more than 10 months after the U.S. Treasury Department  implicated  the North Korea-backed hacking group for the theft of $620 million from the Ronin cross-chain bridge. Then in September 2022, the U.S. government  announced  the recovery of more than $30 million worth of cryptocurrency, representing 10% of the stolen funds. Økokrim said it worked with international law enforcement partners to pursue and piece together the money trail, thereby making it more difficult for criminal actors to carry out money laundering activities. "Th...

Unknown malware presents a significant cybersecurity threat and can cause serious damage to organizations and individuals alike. When left undetected, malicious code can gain access to confidential information, corrupt data, and allow attackers to gain control of systems. Find out how to avoid these circumstances and detect unknown malicious behavior efficiently.  Challenges of new threats' detection While known malware families are more predictable and can be detected more easily, unknown threats can take on a variety of forms, causing a bunch of challenges for their detection: Malware developers use polymorphism, which enables them to modify the malicious code to generate unique variants of the same malware.  There is malware that is still not identified and doesn't have any rulesets for detection. Some threats can be Fully UnDetectable (FUD) for some time and challenge perimeter security.  The code is often encrypted, making it difficult to detect by signature-...

Russia's cyber attacks against Ukraine surged by 250% in 2022 when compared to two years ago, Google's Threat Analysis Group (TAG) and Mandiant disclosed in a new joint report. The targeting, which  coincided  and has  since persisted  following the country's military invasion of Ukraine in February 2022, focused heavily on the Ukrainian government and military entities, alongside critical infrastructure, utilities, public services, and media sectors. Mandiant  said  it observed, "more destructive cyber attacks in Ukraine during the first four months of 2022 than in the previous eight years with attacks peaking around the start of the invasion." As many as six unique wiper strains – including WhisperGate, HermeticWiper, IsaacWiper, CaddyWiper, Industroyer2, and SDelete – have been deployed against Ukrainian networks, suggesting a willingness on the part of Russian threat actors to forgo persistent access. Phishing attacks aimed at NATO countries witnes...

The cyber espionage threat actor tracked as  Earth Kitsune  has been observed deploying a new backdoor called WhiskerSpy as part of a social engineering campaign. Earth Kitsune, active since at least 2019, is  known  to primarily target individuals interested in North Korea with self-developed malware such as dneSpy and agfSpy. Previously documented intrusions have entailed the use of watering holes that leverage browser exploits in Google Chrome and Internet Explorer to activate the infection chain. The differentiating factor in the latest attacks is a shift toward social engineering to trick users into visiting compromised websites related to North Korea, according to a new report from Trend Micro released last week. The cybersecurity company said the website of an unnamed pro-North Korean organization was hacked and modified to distribute the WhiskerSpy implant. The compromise was discovered at the end of last year. "When a targeted visitor tries to watch vi...

Samsung has announced a new feature called Message Guard that comes with safeguards to protect users from malware and spyware via what's referred to as zero-click attacks . The South Korean chaebol said the solution "preemptively" secures users' devices by "limiting exposure to invisible threats disguised as image attachments." The security feature, available on Samsung Messages and Google Messages, is currently limited to the Samsung Galaxy S23 series, with plans to expand it to other Galaxy smartphones and tablets later this year that are running on One UI 5.1 or higher. It's also the latest security guardrail erected by Samsung, which also includes the Knox security platform that the company said already offers protection from attacks using video and audio formats. Zero-click attacks are highly-targeted and sophisticated attacks that exploit previously unknown flaws (i.e., zero-days) in software to trigger execution of malicious code without re...
