Security researchers on Tuesday uncovered new delivery and evasion techniques adopted by Agent Tesla remote access trojan (RAT) to get around defense barriers and monitor its victims. Typically spread through social engineering lures, the Windows spyware not only now targets Microsoft's Antimalware Scan Interface ( AMSI ) in an attempt to defeat endpoint protection software, it also employs a multi-stage installation process and makes use of Tor and Telegram messaging API to communicate with a command-and-control (C2) server. Cybersecurity firm Sophos , which observed two versions of Agent Tesla — version 2 and version 3 — currently in the wild, said the changes are yet another sign of Agent Tesla's constant evolution designed to make a sandbox and static analysis more difficult. "The differences we see between v2 and v3 of Agent Tesla appear to be focused on improving the success rate of the malware against sandbox defenses and malware scanners, and on providing more...

The Office of the Washington State Auditor (SAO) on Monday said it's investigating a security incident that resulted in the compromise of personal information of more than 1.6 million people who filed for unemployment claims in the state in 2020. The SAO blamed the breach on a software vulnerability in Accellion's File Transfer Appliance (FTA) service, which allows organizations to share sensitive documents with users outside their organization securely. "During the week of January 25, 2021, Accellion confirmed that an unauthorized person gained access to SAO files by exploiting a vulnerability in Accellion's file transfer service," the SAO  said  in a statement. The accessed information is said to have contained personal details of Washington state residents who filed unemployment insurance claims in 2020, as well as other data from local governments and state agencies. The exact information that may have been compromised include: Full name Social securi...

Security Operations is a 24 x 7 job. It does not stop for weekends or holidays or even that much-needed coffee break after the first hour of the shift is complete. We all know this. Every SOC engineer is hoping for some rest at some point. One of my favorite jokes when talking about Security Operations is "3 SOC engineers walked into a bar…" That the joke. No SOC engineers have time to do that. They get it. They laugh. So why is this all true? Let us explore that a little bit. Demand for experienced SOC engineers far surpasses the available talent. Event volume levels boggle the imagination compared to even just a few years ago. Utilization of tools to their utmost capability has often not been a priority.  In the Security Operations space, we have been using SIEM's for many years with varying degrees of deployments, customization, and effectiveness. For the most part, they have been a helpful tool for Security Operations. But they can be better. Like any tool, t...

SonicWall on Monday warned of active exploitation attempts against a zero-day vulnerability in its Secure Mobile Access (SMA) 100 series devices. The flaw, which affects both physical and virtual SMA 100 10.x devices (SMA 200, SMA 210, SMA 400, SMA 410, SMA 500v), came to light after the NCC Group on Sunday  alerted  it had detected "indiscriminate use of an exploit in the wild." Details of the exploit have not been disclosed to prevent the zero-day from being misused further, but a patch is expected to be available by the end of day on February 2, 2021. "A few thousand devices are impacted," SonicWall  said  in a statement, adding, "SMA 100 firmware prior to 10.x is unaffected by this zero-day vulnerability." On January 22, The Hacker News exclusively  revealed  that SonicWall had been breached as a consequence of a coordinated attack on its internal systems by exploiting "probable zero-day vulnerabilities" in its SMA 100 series remote acc...

Cybersecurity researchers today disclosed a new supply chain attack targeting online gamers by compromising the update mechanism of NoxPlayer, a free Android emulator for PCs and Macs. Dubbed " Operation NightScout " by Slovak cybersecurity firm ESET, the highly-targeted surveillance campaign involved distributing three different malware families via tailored malicious updates to selected victims based in Taiwan, Hong Kong, and Sri Lanka. NoxPlayer, developed by Hong Kong-based BigNox, is an Android emulator that allows users to play mobile games on PC, with support for keyboard, gamepad, script recording, and multiple instances. It is  estimated  to have over 150 million users in more than 150 countries. First signs of the ongoing attack are said to have originated around September 2020, from when the compromise continued until "explicitly malicious activity" was uncovered on January 25, prompting ESET to report the incident to BigNox. "Based on the comp...

We likely all agree that 2020 was a year we won't soon forget - for many reasons. One area particularly impacted last year was (and continues to be) cybersecurity.  While Internet access allowed many businesses to continue functioning during the COVID-19 stay at home requirements, the unprecedented number of people accessing company assets remotely introduced many new challenges for cybersecurity professionals. With a history of leveraging societal maladies to their advantage, cyber criminals leverage the confusion and unpreparedness created by the global pandemic in their cyber attacks.  In just the last two months of 2020, several high-profile organizations and government entities were successfully attacked using clever approaches that were overlooked by cybersecurity experts. Making sense of how attacks have changed and what new defensive strategies should be taken is no easy task. Cybersecurity company Cynet will help by reviewing the 2020 high profile attacks in depth...

A financially-motivated threat actor notorious for its cryptojacking attacks has leveraged a revised version of their malware to target cloud infrastructures using vulnerabilities in web server technologies, according to new research. Deployed by the China-based cybercrime group  Rocke , the Pro-Ocean cryptojacking malware now comes with improved rootkit and worm capabilities, as well as harbors new evasion tactics to sidestep cybersecurity companies' detection methods, Palo Alto Networks' Unit 42 researchers  said  in a Thursday write-up. "Pro-Ocean uses known vulnerabilities to target cloud applications," the researchers detailed. "In our analysis, we found Pro-Ocean targeting Apache ActiveMQ ( CVE-2016-3088 ), Oracle WebLogic ( CVE-2017-10271 ) and Redis (unsecure instances)." "Once installed, the malware kills any process that uses the CPU heavily, so that it's able to use 100% of the CPU and mine Monero efficiently." First documented...

A "severe" vulnerability in GNU Privacy Guard (GnuPG)'s Libgcrypt encryption software could have allowed an attacker to write arbitrary data to the target machine, potentially leading to remote code execution. The flaw, which affects version 1.9.0 of libgcrypt, was discovered on January 28 by Tavis Ormandy of Project Zero, a security research unit within Google dedicated to finding zero-day bugs in hardware and software systems. No other versions of Libgcrypt are affected by the vulnerability. "There is a  heap buffer overflow  in libgcrypt due to an incorrect assumption in the block buffer management code," Ormandy  said . "Just decrypting some data can overflow a heap buffer with attacker controlled data, no verification or signature is validated before the vulnerability occurs." GnuPG addressed the weakness almost immediately within a day after disclosure, while urging users to  stop using  the vulnerable version. The latest version can be dow...

Google Project Zero on Thursday disclosed details of a new security mechanism that Apple quietly added to iOS 14 as a countermeasure to prevent attacks that were recently found to leverage zero-days in its messaging app. Dubbed " BlastDoor ," the improved sandbox system for iMessage data was disclosed by Samuel Groß, a Google Project Zero researcher tasked with studying zero-day vulnerabilities in hardware and software systems. "One of the major changes in iOS 14 is the introduction of a new, tightly sandboxed 'BlastDoor' service which is now responsible for almost all parsing of untrusted data in iMessages," Groß  said . "Furthermore, this service is written in Swift, a (mostly) memory safe language which makes it significantly harder to introduce classic memory corruption vulnerabilities into the code base." The development is a consequence of a  zero-click exploit  that leveraged an Apple iMessage flaw in iOS 13.5.1 to get around security p...

The pressure on small to medium-sized enterprises to protect their organizations against cyberthreats is astronomical. These businesses face the same threats as the largest enterprises, experience the same (relative) damages and consequences when breaches occur as the largest enterprises but are forced to protect their organizations with a fraction of the resources as the largest enterprises.  Cybersecurity company Cynet just released findings from a survey of 200 CISOs in charge of small security teams ( Download here ) to shine "a spotlight into the challenges of small security teams everywhere." In addition to better understanding the challenges these CISOs face, the 2021 Survey of CISOs with Small Security Teams delves into the strategies CISOs will employ to ensure their organizations are protected from the ongoing onslaught of cyber threats - all while saddled with limited budgets and headcount. The survey findings will also be presented in a live webinar,  register...

A "persistent attacker group" with alleged ties to Hezbollah has retooled its malware arsenal with a new version of a remote access Trojan (RAT) to break into companies worldwide and extract valuable information. In a  new report  published by the ClearSky research team on Thursday, the Israeli cybersecurity firm said it identified at least 250 public-facing web servers since early 2020 that have been hacked by the threat actor to gather intelligence and steal the company's databases. The orchestrated intrusions hit a slew of companies located in the U.S., the U.K., Egypt, Jordan, Lebanon, Saudi Arabia, Israel, and the Palestinian Authority, with a majority of the victims representing telecom operators (Etisalat, Mobily, Vodafone Egypt), internet service providers (SaudiNet, TE Data), and hosting and infrastructure service providers (Secured Servers LLC, iomart). First documented in 2015,  Volatile Cedar  (or Lebanese Cedar) has been known to penetrate a large n...

Researchers have disclosed a new family of Android malware that abuses accessibility services in the device to hijack user credentials and record audio and video. Dubbed " Oscorp " by Italy's CERT-AGID and spotted by  AddressIntel , the malware "induce(s) the user to install an accessibility service with which [the attackers] can read what is present and what is typed on the screen." So named because of the title of the login page of its command-and-control (C2) server, the malicious APK (called "Assistenzaclienti.apk" or "Customer Protection") is  distributed  via a domain named "supportoapp[.]com," which upon installation, requests intrusive permissions to enable the accessibility service and establishes communications with a C2 server to retrieve additional commands. Furthermore, the malware repeatedly reopens the Settings screen every eight seconds until the user turns on permissions for accessibility and device usage stati...
