A group of academics from the North Carolina State University and Dokuz Eylul University have demonstrated what they say is the “first side-channel attack” on homomorphic encryption that could be exploited to leak data as the encryption process is underway. “Basically, by monitoring power consumption in a device that is encoding data for homomorphic encryption,

With the COVID-19 pandemic continuing to impact, and perhaps permanently changing, how we work, cybercriminals again leveraged the distraction in new waves of cyberattacks. Over the course of 2021 we saw an increase in multiple attack approaches; some old, some new. Phishing and ransomware continued to grow from previous years, as expected, while new attacks

Distributed denial-of-service (DDoS) attacks leveraging a new amplification technique called TCP Middlebox Reflection have been detected for the first time in the wild, six months after the novel attack mechanism was presented in theory. “The attack […] abuses vulnerable firewalls and content filtering systems to reflect and amplify TCP traffic to a victim machine, creating

Details of a new nation-state sponsored phishing campaign have been uncovered setting its sights on European governmental entities in what’s seen as an attempt to obtain intelligence on refugee and supply movement in the region. Enterprise security company Proofpoint, which detected the malicious emails for the first time on February 24, 2022, dubbed the social

As many as five security vulnerabilities have been disclosed in the PJSIP open-source multimedia communication library that could be abused by an attacker to trigger arbitrary code execution and denial-of-service (DoS) in applications that use the protocol stack. The weaknesses were identified and reported by JFrog’s Security Research team, following which the project maintainers released

A new data wiper malware has been observed deployed against an unnamed Ukrainian government network, a day after destructive cyber attacks struck multiple entities in the country preceding the start of Russia’s military invasion. Slovak cybersecurity firm ESET dubbed the new malware “IsaacWiper,” which it said was detected on February 24 in an organization that

It is predicted that 3.5 million jobs will be unfilled in the field of cybersecurity by the end of this year. Several of these jobs pay very well, and in most cases, you don’t even need a college degree to get hired. The most important thing is to have the skills and certifications. The All-In-One

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) expanded its Known Exploited Vulnerabilities Catalog to include a recently disclosed zero-day flaw in the Zimbra email platform citing evidence of active exploitation in the wild. Tracked as CVE-2022-24682 (CVSS score: 6.1), the issue concerns a cross-site scripting (XSS) vulnerability in the Calendar feature in Zimbra Collaboration

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) last week published an industrial control system (ICS) advisory related to multiple vulnerabilities impacting Schneider Electric’s Easergy medium voltage protection relays. “Successful exploitation of these vulnerabilities may disclose device credentials, cause a denial-of-service condition, device reboot, or allow an attacker to gain full control of the relay,”

A group of academics from Tel Aviv University have disclosed details of now-patched “severe” design flaws affecting about 100 million Android-based Samsung smartphones that could have resulted in the extraction of secret cryptographic keys. The shortcomings are the result of an analysis of the cryptographic design and implementation of Android’s hardware-backed Keystore in Samsung’s Galaxy

There’s something about craftsmanship. It’s personal, its artistry, and it can be incredibly effective in achieving its goals. On the other hand, mass-market production can be effective in other ways, through speed, efficiency, and cost savings. The story of data centers is one of going from craftsmanship – where every individual machine is a pet

The modular Windows crimeware platform known as TrickBot formally shuttered its infrastructure on Thursday after reports emerged of its imminent retirement amid a lull in its activity for almost two months, marking an end to one of the most persistent malware campaigns in recent years. “TrickBot is gone… It is official now as of Thursday,

Ukraine’s Computer Emergency Response Team (CERT-UA) has warned of Belarusian state-sponsored hackers targeting its military personnel and related individuals as part of a phishing campaign mounted amidst Russia’s military invasion of the country. “Mass phishing emails have recently been observed targeting private ‘i.ua’ and ‘meta.ua’ accounts of Ukrainian military personnel and related individuals,” the CERT-UA

A new malware capable of controlling social media accounts is being distributed through Microsoft’s official app store in the form of trojanized gaming apps, infecting more than 5,000 Windows machines in Sweden, Bulgaria, Russia, Bermuda, and Spain. Israeli cybersecurity company Check Point dubbed the malware “Electron Bot,” in reference to a command-and-control (C2) domain used

Cybersecurity agencies from the U.K. and the U.S. have laid bare a new malware used by the Iranian government-sponsored advanced persistent threat (APT) group in attacks targeting government and commercial networks worldwide. “MuddyWater actors are positioned both to provide stolen data and accesses to the Iranian government and to share these with other malicious cyber

Cybersecurity researchers have taken the wraps off a previously undocumented and stealthy custom malware called SockDetour that targeted U.S.-based defense contractors with the goal of being used as a secondary implant on compromised Windows hosts. “SockDetour is a backdoor that is designed to remain stealthily on compromised Windows servers so that it can serve as

The Russian government on Thursday warned of cyber attacks aimed at domestic critical infrastructure operators, as the country’s full-blown invasion of Ukraine enters the second day. In addition to cautioning of the “threat of an increase in the intensity of computer attacks,” Russia’s National Computer Incident Response and Coordination Center said that the “attacks can

Cisco has released software updates to address four security vulnerabilities in its software that could be weaponized by malicious actors to take control of affected systems. The most critical of the flaws is CVE-2022-20650 (CVSS score: 8.8), which relates to a command injection flaw in the NX-API feature of Cisco NX-OS Software that stems from
