Nation-state operators with nexus to Iran are increasingly turning to ransomware as a means of generating revenue and intentionally sabotaging their targets, while also engaging in patient and persistent social engineering campaigns and aggressive brute force attacks. No less than six threat actors affiliated with the West Asian country have been discovered deploying ransomware to
A malicious campaign has been found leveraging a technique called domain fronting to hide command-and-control traffic by leveraging a legitimate domain owned by the Myanmar government to route communications to an attacker-controlled server with the goal of evading detection. The threat, which was observed in September 2021, deployed Cobalt Strike payloads as a stepping stone
Cybersecurity agencies from Australia, the U.K., and the U.S. on Wednesday released a joint advisory warning of active exploitation of Fortinet and Microsoft Exchange ProxyShell vulnerabilities by Iranian state-sponsored actors to gain initial access to vulnerable systems for follow-on activities, including data exfiltration and ransomware. The threat actor is believed to have leveraged multiple Fortinet
Meta, the company formerly known as Facebook, announced Tuesday that it took action against four separate malicious cyber groups from Pakistan and Syria who were found targeting people in Afghanistan, as well as journalists, humanitarian organizations, and anti-regime military forces in the West Asian country. The Pakistani threat actor, dubbed SideCopy, is said to have
Cybersecurity researchers have demonstrated yet another variation of the Rowhammer attack affecting all DRAM (dynamic random-access memory) chips that bypasses currently deployed mitigations, thereby effectively compromising the security of the devices. The new technique — dubbed “Blacksmith” (CVE-2021-42114, CVSS score: 9.0) — is designed to trigger bit flips on target refresh rate-enabled DRAM chips with
No fewer than 1,220 Man-in-the-Middle (MitM) phishing websites have been discovered as targeting popular online services like Instagram, Google, PayPal, Apple, Twitter, and LinkedIn with the goal of hijacking users’ credentials and carrying out further follow-on attacks. The findings come from a new study undertaken by a group of researchers from Stony Brook University and
A new politically-motivated hacker group named “Moses Staff” has been linked to a wave of targeted attacks targeting Israeli organizations since September 2021 with the goal of plundering and leaking sensitive information prior to encrypting their networks, with no option to regain access or negotiate a ransom. “The group openly states that their motivation in
Lazarus, the North Korea-affiliated state-sponsored group, is attempting to once again target security researchers with backdoors and remote access trojans using a trojanized pirated version of the popular IDA Pro reverse engineering software. The findings were reported by ESET security researcher Anton Cherepanov last week in a series of tweets. IDA Pro is an Interactive
A new analysis of website fingerprinting (WF) attacks aimed at the Tor web browser has revealed that it’s possible for an adversary to glean a website frequented by a victim, but only in scenarios where the threat actor is interested in a specific subset of the websites visited by users. “While attacks can exceed 95%
The U.S. Federal Bureau of Investigation (FBI) on Saturday confirmed unidentified threat actors have breached one of its email servers to blast hoax messages about a fake “sophisticated chain attack.” The incident, which was first publicly disclosed by threat intelligence non-profit SpamHaus, involved sending rogue warning emails with the subject line “Urgent: Threat actor in
A state-sponsored threat actor allegedly affiliated with Iran has been linked to a series of targeted attacks aimed at internet service providers (ISPs) and telecommunication operators in Israel, Morocco, Tunisia, and Saudi Arabia, as well as a ministry of foreign affairs (MFA) in Africa, new findings reveal. The intrusions, staged by a group tracked as
Though we are recovering from the worst pandemic, cyber threats have shown no sign of downshifting, and cybercriminals are still not short of malicious and advanced ways to achieve their goals. The Global Threat Landscape Report indicates a drastic rise in sophisticated cyberattacks targeting digital infrastructures, organizations, and individuals in 2021. Threats can take different
Threat actors are increasingly banking on the technique of HTML smuggling in phishing campaigns as a means to gain initial access and deploy an array of threats, including banking malware, remote administration trojans (RATs), and ransomware payloads. Microsoft 365 Defender Threat Intelligence Team, in a new report published Thursday, disclosed that it identified infiltrations distributing
Google researchers on Thursday disclosed that it found a watering hole attack in late August exploiting a now-parched zero-day in macOS operating system and targeting Hong Kong websites related to a media outlet and a prominent pro-democracy labor and political group to deliver a never-before-seen backdoor on compromised machines. “Based on our findings, we believe
Researchers from Qihoo 360’s Netlab security team have released details of a new evolving botnet called “Abcbot” that has been observed in the wild with worm-like propagation features to infect Linux systems and launch distributed denial-of-service (DDoS) attacks against targets. While the earliest version of the botnet dates back to July 2021, new variants observed
A new cyber mercenary hacker-for-hire group dubbed “Void Balaur” has been linked to a string of cyberespionage and data theft activities targeting thousands of entities as well as human rights activists, politicians, and government officials around the world at least since 2015 for financial gain while lurking in the shadows. Named after a many-headed dragon
The operators of TrickBot trojan are collaborating with the Shathak threat group to distribute their wares, ultimately leading to the deployment of Conti ransomware on infected machines. “The implementation of TrickBot has evolved over the years, with recent versions of TrickBot implementing malware-loading capabilities,” Cybereason security analysts Aleksandar Milenkoski and Eli Salem said in a
