Microsoft has patched a worm-like vulnerability in its Teams workplace video chat and collaboration platform that could have allowed attackers to take over an organization's entire roster of Teams accounts just by sending participants a malicious link to an innocent-looking image. The flaw, impacting both desktop and web versions of the app, was discovered by cybersecurity researchers at CyberArk. After the findings were responsibly disclosed on March 23, Microsoft patched the vulnerability in an update released on April 20. "Even if an attacker doesn't gather much information from a Teams' account, they could still use the account to traverse throughout an organization (just like a worm)," CyberArk's Omer Tsarfati said. "Eventually, the attacker could access all the data from your organization's Teams accounts — gathering confidential information, meetings and calendar information, competitive data, secrets, passwords, private information, ...

Cybersecurity researchers from ESET on Thursday said they took down a portion of a malware botnet comprising at least 35,000 compromised Windows systems that attackers were secretly using to mine Monero cryptocurrency. The botnet, named "VictoryGate," has been active since May 2019, with infections mainly reported in Latin America, particularly Peru accounting for 90% of the compromised devices. "The main activity of the botnet is mining Monero cryptocurrency," ESET said . "The victims include organizations in both public and private sectors, including financial institutions." ESET said it worked with dynamic DNS provider No-IP to take down the malicious command-and-control (C2) servers and that it set up fake domains (aka sinkholes) to monitor the botnet's activity. The sinkhole data shows that between 2,000 and 3,500 infected computers connected to the C2 servers on a daily basis during February and March this year. According to ESET res...

In a recent highly targeted BEC attack, hackers managed to trick three British private equity firms into wire-transferring a total of $1.3 million to the bank accounts fraudsters have access to — while the victimized executives thought they closed an investment deal with some startups. According to the cybersecurity firm Check Point, who shared its latest investigation with The Hacker News, nearly $700,000 of the total wire transferred amount has permanently lost to the attackers, with the rest of the amount recovered after researchers alerted the targeted firms in time. Dubbed ' The Florentine Banker ,' the sophisticated cybercrime gang behind this attack, "seems to have honed their techniques over multiple attacks, from at least several years of activity and has proven to be a resourceful adversary, quickly adapting new situations," the researchers said. 'The techniques they use, especially the lookalike domains technique, present a severe threat — not ...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

Watch out Apple users! The default mailing app pre-installed on millions of iPhones and iPads has been found vulnerable to two critical flaws that attackers are exploiting in the wild, at least, from the last two years to spy on high-profile victims. The flaws could eventually let remote hackers secretly take complete control over Apple devices just by sending an email to any targeted individual with his email account logged-in to the vulnerable app. According to cybersecurity researchers at ZecOps, the bugs in question are remote code execution flaws that reside in the MIME library of Apple's mail app—first, due to an out-of-bounds write bug and second, is a heap overflow issue. Though both flaws get triggered while processing the content of an email, the second flaw is more dangerous because it can be exploited with 'zero-click,' where no interaction is required from the targeted recipients. 8-Years-Old Apple Zero-Days Exploited in the Wild According to the...

A Chinese hacking group has been found leveraging a new exploit chain in iOS devices to install a spyware implant targeting the Uyghur Muslim minority in China's autonomous region of Xinjiang. The findings, published by digital forensics firm Volexity , reveal that the exploit — named "Insomnia" — works against iOS versions 12.3, 12.3.1, and 12.3.2 using a flaw in WebKit that was patched by Apple with the release of iOS 12.4 in July 2019. Volexity said the attacks were carried out by a state-sponsored hacking group it calls Evil Eye , the same threat actor that it said was behind a series of attacks against the Uyghurs last September following a bombshell disclosure by Google's Project Zero team . China has long considered Xinjiang a breeding ground for " separatists, terrorists and religious extremists ," with the residents of the region — ethnically Turkic Muslims — thrown into concentration camps , and subjected to persecution and high-tech surv...

Cybersecurity firm Cynet today announced the launch of a first of its kind challenge to enable Incident Response professionals to test their skills with 25 forensic challenges that were built by top researchers and analysts. The challenge is available on https://incident-response-challenge.com/ and is open to anyone willing to test his or her investigation skills, between April 21st and May 15th. What's more interesting is that there's a USD 5000 prize for the first-place winner of the challenge. Forensic investigation is at the core of any IR processes and provides the critical path from the initial stage of suspicion or limited attack view to the concrete and actionable knowledge on the attack's root cause and the impact that is essential for recovery and restore operations. The challenge of the incident responder is to identify and collect the scattered traces the attackers have left them and connect the dots to understand the how, what, and where of the atta...

A cybersecurity researcher today publicly disclosed technical details and PoC for 4 unpatched zero-day vulnerabilities affecting an enterprise security software offered by IBM after the company refused to acknowledge the responsibly submitted disclosure. The affected premium product in question is IBM Data Risk Manager (IDRM) that has been designed to analyze sensitive business information assets of an organization and determine associated risks. According to Pedro Ribeiro from Agile Information Security firm, IBM Data Risk Manager contains three critical severity vulnerabilities and a high impact bug, all listed below, which can be exploited by an unauthenticated attacker reachable over the network, and when chained together could also lead to remote code execution as root. Authentication Bypass Command Injection Insecure Default Password Arbitrary File Download Ribeiro successfully tested the flaws against IBM Data Risk Manager version 2.0.1 to 2.0.3, which is not the la...
