Atlassian has rolled out fixes for a  critical security flaw  in Bitbucket Server and Data Center that could lead to the execution of malicious code on vulnerable installations. Tracked as  CVE-2022-36804  (CVSS score: 9.9), the issue has been characterized as a command injection vulnerability in multiple endpoints that could be exploited via specially crafted HTTP requests. "An attacker with access to a public Bitbucket repository or with read permissions to a private one can execute arbitrary code by sending a malicious HTTP request," Atlassian  said  in an advisory. The shortcoming, discovered and reported by security researcher  @TheGrandPew  impacts all versions of Bitbucket Server and Datacenter released after 6.10.17, inclusive of 7.0.0 and newer - Bitbucket Server and Datacenter 7.6 Bitbucket Server and Datacenter 7.17 Bitbucket Server and Datacenter 7.21 Bitbucket Server and Datacenter 8.0 Bitbucket Server and Datacenter 8.1 Bitbucket Server and Datacenter 8.2, and

Password management service LastPass confirmed a security incident that resulted in the theft of certain source code and technical information. The security breach is said to have occurred two weeks ago, targeting its development environment. No customer data or encrypted passwords were accessed, although the company provided no further details regarding the hack and what source code was stolen. "An unauthorized party gained access to portions of the LastPass development environment through a single compromised developer account and took portions of source code and some proprietary LastPass technical information," LastPass CEO Karim Toubba  said . Amidst ongoing investigation into the incident, the company said it has engaged the services of a leading cybersecurity and forensics firm and that it has implemented additional countermeasures. LastPass, however, didn't elaborate on the exact mitigation techniques that it used to strengthen its environment. It also reiterated that the

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint . Unprotected endpoints provide vulnerable entry points to launch devastating cyberattacks. With IT teams needing to protect more endpoints—and more kinds of endpoints—than ever before, that perimeter has become more challenging to defend. You need to improve your endpoint security, but where do you start? That's where this guide comes in.  We've curated the top 10 must-know endpoint security tips that every IT and security professional should have in their arsenal. From identifying entry points to implementing EDR solutions, we'll dive into the insights you need to defend your endpoints with confidence.  1.

Nation-state threat actors are  increasingly adopting  and integrating the Sliver command-and-control (C2) framework in their intrusion campaigns as a replacement for Cobalt Strike. "Given Cobalt Strike's popularity as an attack tool, defenses against it have also improved over time," Microsoft security experts  said . "Sliver thus presents an attractive alternative for actors looking for a lesser-known toolset with a low barrier for entry." Sliver, first made public in late 2019 by cybersecurity company BishopFox, is a Go-based  open source C2 platform  that supports user-developed extensions, custom implant generation, and other commandeering options. "A C2 framework usually includes a server that accepts connections from implants on a compromised system, and a client application that allows the C2 operators to interact with the implants and launch malicious commands," Microsoft said. Besides facilitating long-term access to infected hosts, the cross-platform kit is also known

The threat actor behind the attacks on  Twilio  and  Cloudflare  earlier this month has been linked to a broader phishing campaign aimed at 136 organizations that resulted in a cumulative compromise of 9,931 accounts. The activity has been condemned  0ktapus  by Group-IB because the initial goal of the attacks was to "obtain Okta identity credentials and two-factor authentication (2FA) codes from users of the targeted organizations." Calling the attacks well designed and executed, the Singapore-headquartered company said the adversary singled out employees of companies that are customers of identity services provider Okta. The modus operandi involved sending targets text messages containing links to phishing sites that impersonated the Okta authentication page of the respective targeted entities. "This case is of interest because despite using low-skill methods it was able to compromise a large number of well-known organizations," Group-IB  said . "Furthe

The threat actor behind the SolarWinds supply chain attack has been linked to yet another "highly targeted" post-exploitation malware that could be used to maintain persistent access to compromised environments. Dubbed  MagicWeb  by Microsoft's threat intelligence teams, the development reiterates Nobelium's commitment to developing and maintaining purpose-built capabilities. Nobelium is the tech giant's moniker for a cluster of activities that came to light with the  sophisticated attack targeting SolarWinds  in December 2020, and which overlaps with the Russian nation-state hacking group widely known as  APT29 , Cozy Bear, or The Dukes. "Nobelium remains highly active, executing multiple campaigns in parallel targeting government organizations, non-governmental organizations (NGOs), intergovernmental organizations (IGOs), and think tanks across the US, Europe, and Central Asia," Microsoft  said . MagicWeb, which shares similarities with another t

In recent months, the House of Representatives has been hard at work drafting various spending bills for the 2023 fiscal year. While these bills provide funding for a vast array of government programs and agencies, there was one thing that really stands out. Collectively, the bills that are making their way through the house  allocate a staggering $15.6 billion to cybersecurity spending . As you could probably guess, the lion's share of this spending ($11.2 billion) is being allocated to the Department of Defense. It is worth noting, however, that nearly $3 billion is going to the Cyber Security and Infrastructure Security Agency (CISA). Although it may be tempting to think of these cybersecurity budget allocations as just another example of excessive government spending, it's worth considering what a $15.6 billion cash infusion will mean for the IT security industry. It's equally important to consider why the US government finds it necessary to ramp up its cybersecurity

The North Korean nation-state group Kimusky has been linked to a new set of malicious activities directed against political and diplomatic entities located in its southern counterpart since early 2022. Russian cybersecurity firm Kaspersky codenamed the cluster  GoldDragon , with the infection chains leading to the deployment of Windows malware designed to file lists, user keystrokes, and stored web browser login credentials. Included among the potential victims are South Korean university professors, think tank researchers, and government officials.  Kimsuky , also known as Black Banshee, Thallium, and Velvet Chollima, is the name given to a prolific North Korean advanced persistent threat (APT) group that targets entities globally, but with a primary focus on South Korea, to gain intelligence on various topics of interest to the regime. Known to be operating since 2012, the group has a history of employing social engineering tactics, spear-phishing, and watering hole attacks to

The Python Package Index, PyPI, on Wednesday sounded the alarm about an ongoing phishing campaign that aims to steal developer credentials and inject malicious updates to legitimate packages. "This is the first known phishing attack against PyPI," the maintainers of the official third-party software repository  said  in a series of tweets. The social engineering attack entails sending security-themed messages that create a false sense of urgency by informing recipients that Google is implementing a mandatory validation process on all packages and that they need to click on a link to complete the validation before September, or risk getting their PyPI modules removed. Should an unsuspecting developer fall for the scheme, users are directed to a lookalike landing page that mimics PyPI's login page and is hosted on Google Sites, from where the entered credentials are captured and abused to unauthorizedly access the accounts and compromise the packages to include malware

Threat actors have begun to use the Tox peer-to-peer instant messaging service as a command-and-control method, marking a shift from its earlier role as a contact method for ransomware negotiations. The findings from Uptycs, which analyzed an Executable and Linkable Format (ELF) artifact (" 72client ") that functions as a bot and can run scripts on the compromised host using the Tox protocol. Tox is a  serverless protocol  for online communications that offers end-to-end encryption (E2EE) protections by making use of the Networking and Cryptography library ( NaCl , pronounced "salt") for encryption and authentication. "The binary found in the wild is a stripped but dynamic executable, making decompilation easier," researchers Siddharth Sharma and Nischay Hedge  said . "The entire binary appears to be written in C, and has only  statically linked  the c-toxcore library." It's worth noting that c-toxcore is a  reference implementation  of

A security researcher who has a long line of work demonstrating novel data exfiltration methods from air-gapped systems has come up with yet another technique that involves sending Morse code signals via LEDs on network interface cards ( NICs ). The approach, codenamed  ETHERLED , comes from Dr. Mordechai Guri , the head of R&D in the Cyber Security Research Center in the Ben Gurion University of the Negev in Israel, who recently outlined  GAIROSCOPE , a method for transmitting data ultrasonically to smartphone gyroscopes. "Malware installed on the device could programmatically control the status LED by blinking or alternating its colors, using documented methods or undocumented firmware commands," Dr. Guri said. "Information can be encoded via simple encoding such as Morse code and modulated over these optical signals. An attacker can intercept and decode these signals from tens to hundreds of meters away." A network interface card, also known as a netwo

From ransomware to breaches, from noncompliance penalties to reputational damage – cyberthreats pose an existential risk to any business. But for SMEs and SMBs, the danger is compounded. These companies realize they  need  an in-house Chief Information Security Officer (CISO) – someone who can assess risks and vulnerabilities, create and execute a comprehensive cybersecurity plan, ensure compliance and safeguard business continuity. Yet unlike large enterprises, most don't have the budget to bring a full-time experienced CISO on board. To bridge this gap, managed service providers (MSPs), managed security service providers (MSSPs), and consulting firms offer virtual CISO (vCISO), or 'CISO-as-a-service' services. The model is simple: instead of hiring a full-time CISO, SMEs and SMBs pay a subscription or a retainer to gain access to expert cyber assistance in the form of a virtual CISO. Staffed by seasoned veteran executives, vCISOs offer C-level assistance in devising and

WordPress sites are being hacked to display fraudulent Cloudflare DDoS protection pages that lead to the delivery of malware such as NetSupport RAT and Raccoon Stealer. "A recent surge in JavaScript injections targeting WordPress sites has resulted in fake DDoS prevent prompts which lead victims to download remote access trojan malware," Sucuri's Ben Martin  said  in a write-up published last week. Distributed denial-of-service (DDoS) protection pages are essential browser verification checks designed to deter bot-driven unwanted and malicious traffic from eating up bandwidth and taking down websites. The new attack vector involves hijacking WordPress sites to display fake DDoS protection pop-ups that, when clicked, ultimately lead to the download of a malicious ISO file ("security_install.iso") to the victim's systems. This is achieved by injecting three lines of code into a JavaScript file ("jquery.min.js"), or alternatively into the active

The threat actors behind a large-scale adversary-in-the-middle (AiTM)  phishing campaign  targeting enterprise users of Microsoft email services have also set their sights on Google Workspace users. "This campaign specifically targeted chief executives and other senior members of various organizations which use [Google Workspace]," Zscaler researchers Sudeep Singh and Jagadeeswar Ramanukolanu  detailed  in a report published this month. The AiTM phishing attacks are said to have commenced in mid-July 2022, following a similar modus operandi as that of a  social engineering campaign  designed to siphon users' Microsoft credentials and even bypass multi-factor authentication. The low-volume Gmail AiTM phishing campaign also entails using the compromised emails of chief executives to conduct further social engineering, with the attacks also utilizing several compromised domains as an intermediate URL redirector to take the victims to the final landing page. Attack cha

DevOps platform GitLab this week issued patches to address a critical security flaw in its software that could lead to arbitrary code execution on affected systems. Tracked as  CVE-2022-2884 , the issue is rated 9.9 on the CVSS vulnerability scoring system and impacts all versions of GitLab Community Edition (CE) and Enterprise Edition (EE) starting from 11.3.4 before 15.1.5, 15.2 before 15.2.3, and 15.3 before 15.3.1. At its core, the security weakness is a case of authenticated remote code execution that can be triggered via the GitHub import API. GitLab credited  yvvdwf  with discovering and reporting the flaw. A successful exploitation of the critical flaw could enable a malicious actor to run malicious code on the target machine, inject malware and backdoors, and seize complete control of the susceptible devices. While the issue has been resolved in versions 15.3.1, 15.2.3, 15.1.5, users also have the option of securing against the flaw by temporarily disabling the GitHub im

The Iranian government-backed actor known as Charming Kitten has added a new tool to its malware arsenal that allows it to retrieve user data from Gmail, Yahoo!, and Microsoft Outlook accounts. Dubbed  HYPERSCRAPE  by Google Threat Analysis Group (TAG), the actively in-development malicious software is said to have been used against less than two dozen accounts in Iran, with the oldest known sample dating back to 2020. The tool was first discovered in December 2021. Charming Kitten, a prolific advanced persistent threat (APT), is believed to be  associated  with Iran's Islamic Revolutionary Guard Corps (IRGC) and has a history of conducting espionage aligned with the interests of the government. Tracked as APT35, Cobalt Illusion, ITG18, Phosphorus, TA453, and Yellow Garuda, elements of the group have also carried out ransomware attacks, suggesting that the threat actor's motives are both espionage and financially driven. "HYPERSCRAPE requires the victim's account

The operators of the XCSSET macOS malware have upped the stakes by making iterative improvements that add support for macOS Monterey by upgrading its source code components to Python 3. "The malware authors have changed from hiding the primary executable in a fake Xcode.app in the initial versions in 2020 to a fake Mail.app in 2021 and now to a fake Notes.app in 2022," SentinelOne researchers Phil Stokes and Dinesh Devadoss  said  in a report. XCSSET, first  documented  by Trend Micro in 2020, has many moving parts that allow it to  harvest sensitive information  from Apple Notes, WeChat, Skype, and Telegram; inject malicious JavaScript code into various websites; and dump cookies from Safari web browser. Infection chains entail using a dropper to compromise users' Xcode projects with the backdoor, with the latter also taking steps to evade detection by masquerading as either system software or the Google Chrome web browser application. The primary executable is an

Ransomware is the de facto threat organizations have faced over the past few years. Threat actors were making easy money by exploiting the high valuation of cryptocurrencies and their victims' lack of adequate preparation.  Think about bad security policies, untested backups, patch management practices not up-to-par, and so forth. It resulted in easy growth for ransomware extortion, a crime that multiple threat actors around the world perpetrate.  Something's changed, though. Crypto valuations have dropped, reducing the monetary appeal of ransomware attacks due to organizations mounting a formidable defense against ransomware. Threat actors have been searching for another opportunity – and found one. It's called data exfiltration, or exfil, a type of espionage causing headaches at organizations worldwide. Let's take a look. The threat to reveal confidential information Information exfiltration is rapidly becoming more prevalent. Earlier this year, incidents at Nvi

A suspected Iranian threat activity cluster has been linked to attacks aimed at Israeli shipping, government, energy, and healthcare organizations as part of an espionage-focused campaign that commenced in late 2020. Cybersecurity firm Mandiant is tracking the group under its uncategorized moniker  UNC3890 , which is believed to conduct operations that align with Iranian interests. "The collected data may be leveraged to support various activities, from hack-and-leak, to enabling kinetic warfare attacks like those that have plagued the shipping industry in recent years," the company's Israel Research Team  noted . Intrusions mounted by the group lead to the deployment of two proprietary pieces of malware: a "small but efficient" backdoor named SUGARUSH and a browser credential stealer called SUGARDUMP that exfiltrates password information to an email address associated with Gmail, ProtonMail, Yahoo, and Yandex. Also employed is a network of command-and-con

A novel data exfiltration technique has been found to leverage a covert ultrasonic channel to leak sensitive information from isolated, air-gapped computers to a nearby smartphone that doesn't even require a microphone to pick up the sound waves. Dubbed  GAIROSCOPE , the adversarial model is the latest addition to a long list of  acoustic, electromagnetic, optical, and thermal approaches  devised by Dr. Mordechai Guri , the head of R&D in the Cyber Security Research Center in the Ben Gurion University of the Negev in Israel. "Our malware generates ultrasonic tones in the resonance frequencies of the  MEMS gyroscope ," Dr. Guri said in a  new paper  published this week. "These inaudible frequencies produce tiny mechanical oscillations within the smartphone's gyroscope, which can be demodulated into binary information." Air-gapping is seen as an  essential security countermeasure  that involves isolating a computer or network and preventing it from es

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday  added  a security flaw impacting Palo Alto Networks PAN-OS to its  Known Exploited Vulnerabilities Catalog , based on evidence of active exploitation. The high-severity vulnerability, tracked as  CVE-2022-0028  (CVSS score: 8.6), is a URL filtering policy misconfiguration that could allow an unauthenticated, remote attacker to carry out reflected and amplified TCP denial-of-service (DoS) attacks. "If exploited, this issue would not impact the confidentiality, integrity, or availability of our products," Palo Alto Networks said in an alert. "However, the resulting denial-of-service (DoS) attack may help obfuscate the identity of the attacker and implicate the firewall as the source of the attack. The weakness impacts the following product versions and has been addressed as part of updates released this month - PAN-OS 10.2 (version < 10.2.2-h2) PAN-OS 10.1 (version < 10.1.6-h6) PAN-O
