The stakes could not be higher for cyber defenders. With the vast amounts of sensitive information, intellectual property, and financial data at risk, the consequences of a data breach can be devastating. According to a report released by  Ponemon institute , the cost of data breaches has reached an all-time high, averaging $4.35 million in 2022. Vulnerabilities in web applications are often the primary gateway for attackers. According to  a World Economic Forum report , just one week after discovering a critical security flaw in a widely used software library (Log4j), more than 100 attempts at exploiting the vulnerability were detected every minute. This illustrates how quickly malicious actors can take advantage of vulnerabilities, highlighting the urgency of regularly assessing and monitoring your system for any vulnerabilities or weak points. The complexity of addressing security challenges in today's digital world is further compounded by the rising use of open-source ...

A cyberespionage actor known as Tick has been attributed with high confidence to a compromise of an East Asian data-loss prevention (DLP) company that caters to government and military entities. "The attackers compromised the DLP company's internal update servers to deliver malware inside the software developer's network, and trojanized installers of legitimate tools used by the company, which eventually resulted in the execution of malware on the computers of the company's customers," ESET researcher Facundo Muñoz  said . Tick , also known as Bronze Butler, REDBALDKNIGHT , Stalker Panda, and Stalker Taurus, is a suspected China-aligned collective that has primarily gone after government, manufacturing, and biotechnology firms in Japan. It's said to be active  since at least 2006 . Other lesser-known targets include Russian, Singaporean, and Chinese enterprises. Attack chains orchestrated by the group have typically leveraged spear-phishing emails and  str...

Microsoft's Patch Tuesday update for March 2023 is rolling out with remediations for a set of  80 security flaws , two of which have come under active exploitation in the wild. Eight of the 80 bugs are rated Critical, 71 are rated Important, and one is rated Moderate in severity. The updates are in  addition to 29 flaws  the tech giant fixed in its Chromium-based Edge browser in recent weeks. The two vulnerabilities that have come under active attack include a Microsoft Outlook privilege escalation flaw ( CVE-2023-23397 , CVSS score: 9.8) and a Windows SmartScreen security feature bypass ( CVE-2023-24880 , CVSS score: 5.1). CVE-2023-23397 is "triggered when an attacker sends a message with an extended MAPI property with a UNC path to an SMB (TCP 445) share on a threat actor-controlled server," Microsoft  said  in a standalone advisory. A threat actor could leverage this flaw by sending a specially crafted email, activating it automatically when it is retrie...

A new Golang-based malware dubbed  GoBruteforcer  has been found targeting web servers running phpMyAdmin, MySQL, FTP, and Postgres to corral the devices into a botnet. "GoBruteforcer chose a Classless Inter-Domain Routing ( CIDR ) block for scanning the network during the attack, and it targeted all IP addresses within that CIDR range," Palo Alto Networks Unit 42 researchers  said . "The threat actor chose CIDR block scanning as a way to get access to a wide range of target hosts on different IPs within a network instead of using a single IP address as a target." GoBruteforcer is mainly designed to single out Unix-like platforms running x86, x64 and ARM architectures, with  the malware attempting to obtain access via a brute-force attack using a list of credentials hard-coded into the binary. If the attack proves to be successful, an internet relay chat ( IRC ) bot is deployed on the victim server to establish communications with an actor-controlled server. ...

Today, the LockBit ransomware is the most active and successful cybercrime organization in the world. Attributed to a Russian Threat Actor, LockBit has stepped out from the shadows of the Conti ransomware group, who were disbanded in early 2022. LockBit ransomware was first discovered in September 2019 and was previously known as ABCD ransomware because of the ".abcd virus" extension first observed. LockBit operates as a Ransomware-as-a-service (RaaS) model. In short, this means that affiliates make a deposit to use the tool, then split the ransom payment with the LockBit group. It has been reported that some affiliates are receiving a share as high of 75%. LockBit's operators have posted advertisements for their affiliate program on Russian-language criminal forums stating they will not operate in Russia or any CIS countries, nor will they work with English-speaking developers unless a Russian-speaking "guarantor" vouches for them.  Initial attack vectors of...

An open source adversary-in-the-middle ( AiTM ) phishing kit has found a number of takers in the cybercrime world for its ability to orchestrate attacks at scale. The Microsoft Threat Intelligence team is tracking the threat actor behind the development of the kit under its emerging moniker  DEV-1101 . An  AiTM phishing attack  typically involves a threat actor attempting to steal and intercept a target's password and session cookies by deploying a proxy server between the user and the website. Such attacks are more effective owing to their ability to circumvent multi-factor authentication (MFA) protections, specifically time-based one-time passwords ( TOTPs ). DEV-1101, per the tech giant, is said to be the party behind several phishing kits that can be purchased or rented by other criminal actors, thereby reducing the effort and resources required to launch a phishing campaign. "The availability of such phishing kits for purchase by attackers is part of the indus...

Government entities and large organizations have been targeted by an unknown threat actor by exploiting a security flaw in Fortinet FortiOS software to result in data loss and OS and file corruption. "The complexity of the exploit suggests an advanced actor and that it is highly targeted at governmental or government-related targets," Fortinet researchers Guillaume Lovet and Alex Kong said in an advisory last week. The zero-day flaw in question is CVE-2022-41328 (CVSS score: 6.5), a medium security path traversal bug in FortiOS that could lead to arbitrary code execution. "An improper limitation of a pathname to a restricted directory vulnerability ('path traversal') [CWE-22] in FortiOS may allow a privileged attacker to read and write arbitrary files via crafted CLI commands," the company noted. The shortcoming impacts FortiOS versions 6.0, 6.2, 6.4.0 through 6.4.11, 7.0.0 through 7.0.9, and 7.2.0 through 7.2.3. Fixes are available in versions 6.4.1...
