Latest Atlassian Confluence Flaw Exploited to Breach Jenkins Project Server

Latest Atlassian Confluence Flaw Exploited to Breach Jenkins Project Server

September 07, 2021Ravie Lakshmanan
The maintainers of Jenkins—a popular open-source automation server software—have disclosed a security breach after unidentified threat actors gained access to one of their servers by exploiting a recently disclosed vulnerability in Atlassian Confluence service to install a cryptocurrency miner. The "successful attack," which is believed to have occurred last week, was mounted against its Confluence service that had been deprecated since October 2019, leading the team to take the server offline, rotate privileged credentials, and reset passwords for developer accounts. "At this time we have no reason to believe that any Jenkins releases, plugins, or source code have been affected," the company  said  in a statement published over the weekend. The disclosure comes as the U.S. Cyber Command  warned  of ongoing mass exploitation attempts in the wild targeting a now-patched critical security vulnerability affecting Atlassian Confluence deployments. Tracked as CVE-2
Critical Cosmos Database Flaw Affected Thousands of Microsoft Azure Customers

Critical Cosmos Database Flaw Affected Thousands of Microsoft Azure Customers

August 27, 2021Ravie Lakshmanan
Cloud infrastructure security company Wiz on Thursday revealed details of a now-fixed Azure Cosmos database vulnerability that could have been potentially exploited to grant any Azure user full admin access to other customers' database instances without any authorization. The flaw, which grants read, write, and delete privileges, has been dubbed " ChaosDB ," with Wiz researchers noting that "the vulnerability has a trivial exploit that doesn't require any previous access to the target environment, and impacts thousands of organizations, including numerous Fortune 500 companies." Cosmos DB is Microsoft's proprietary  NoSQL database  that's advertised as "a fully managed service" that "takes database administration off your hands with automatic management, updates and patching." The Wiz Research Team reported the issue to Microsoft on August 12, after which the Windows maker took steps to mitigate the issue within 48 hours of r

Researchers Detail Modus Operandi of ShinyHunters Cyber Crime Group

August 23, 2021Ravie Lakshmanan
ShinyHunters, a notorious cybercriminal underground group that's been on a data breach spree since last year, has been observed searching companies' GitHub repository source code for vulnerabilities that can be abused to stage larger scale attacks, an analysis of the hackers' modus operandi has revealed. "Primarily operating on Raid Forums, the collective's moniker and motivation can partly be derived from their avatar on social media and other forums: a shiny Umbreon Pokémon," Intel 471 researchers said in a report shared with The Hacker News. "As Pokémon players hunt and collect "shiny" characters in the game, ShinyHunters collects and resells user data." The revelation comes as the  average cost of a data breach  rose from $3.86 million to $4.24 million, making it the highest average cost in 17 years, with compromised credentials responsible for 20% of the breaches reported by over 500 organizations. Since rising to prominence in A
Chinese Hackers Believed to be Behind Second Cyberattack on Air India

Chinese Hackers Believed to be Behind Second Cyberattack on Air India

June 13, 2021Ravie Lakshmanan
Even as a massive data breach affecting Air India came to light the previous month, India's flag carrier airline appears to have suffered a separate cyber assault that lasted for a period of at least two months and 26 days, new research has revealed, which attributed the incident with moderate confidence to a Chinese nation-state threat actor called APT41. Group-IB dubbed the campaign "ColunmTK" based on the names of command-and-control (C2) server domains that were used for facilitating communications with the compromised systems.  "The potential ramifications of this incident for the entire airline industry and carriers that might yet discover traces of ColunmTK in their networks are significant," the Singapore-headquartered threat hunting company  said . While Group-IB alluded that this may have been a supply chain attack targeting SITA, the Swiss aviation information technology company told The Hacker News that they are two different security incidents.
Using Breached Password Detection Services to Prevent Cyberattack

Using Breached Password Detection Services to Prevent Cyberattack

June 10, 2021The Hacker News
Bolstering password policies in your organization is an important part of a robust cybersecurity strategy. Cybercriminals are using compromised accounts as one of their favorite tactics to infiltrate business-critical environments; as we've seen in recent news, these attacks can be dangerous and financially impactful. Unfortunately, account compromise is a very successful attack method and requires much less effort than other attack vectors. One of the essential types of password protection recommended by noted cybersecurity standards is  breached password detection . Hackers often use known breached password lists in credential stuffing or password spraying attacks. Here are some critical criteria to consider when your sysadmins are evaluating breached password protection solutions.  Breached password recommendations In the last few years, password security recommendations have evolved past the traditional recommendations regarding password security.  Businesses have used M
Can Data Protection Systems Prevent Data At Rest Leakage?

Can Data Protection Systems Prevent Data At Rest Leakage?

May 13, 2021The Hacker News
Protection against insider risks works when the process involves controlling the data transfer channels or examining data sources. One approach involves preventing USB flash drives from being copied or sending them over email. The second one concerns preventing leakage or fraud in which an insider accesses files or databases with harmful intentions. What's the best way to protect your data? It seems obvious that prevention is the best way to solve any problem. In most cases, DCAP (data-centric audit and protection) and DAM (database activity monitoring) is sufficient. Both serve the purpose of protecting data at rest. The following example illustrates the approach we found in the Russian legal system. An employee of the Federal Migration Service in one of the Russian regions was approached by his friend, who asked him to hide information about two offenses in his file in the migrant database. The employee knew that this could be done remotely, accessed the database from home,
Passwordstate Warns of Ongoing Phishing Attacks Following Data Breach

Passwordstate Warns of Ongoing Phishing Attacks Following Data Breach

April 30, 2021Ravie Lakshmanan
Click Studios, the Australian software firm which confirmed a  supply chain attack  affecting its Passwordstate password management application, has warned customers of an ongoing phishing attack by an unknown threat actor. "We have been advised a bad actor has commenced a phishing attack with a small number of customers having received emails requesting urgent action," the company  said  in an updated advisory released on Wednesday. "These emails are not sent by Click Studios." Last week, Click Studios said attackers had employed sophisticated techniques to compromise Passwordstate's update mechanism, using it to drop malware on user computers. Only customers who performed In-Place Upgrades between April 20, 8:33 PM UTC, and April 22, 0:30 AM UTC are said to be affected. While Passwordstate serves about 29,000 customers, the Adelaide-based firm maintained that the total number of impacted customers is very low. It's also urging users to refrain from po
3.2 Billion Leaked Passwords Contain 1.5 Million Records with Government Emails

3.2 Billion Leaked Passwords Contain 1.5 Million Records with Government Emails

April 26, 2021Ravie Lakshmanan
A staggering number of 3.28 billion passwords linked to 2.18 billion unique email addresses were exposed in what's one of the largest data dumps of breached usernames and passwords. In addition, the leak includes 1,502,909 passwords associated with email addresses from government domains across the world, with the U.S. government alone taking up 625,505 of the exposed passwords, followed by the U.K (205,099), Australia (136,025), Brazil (68,535), and Canada (50,726). The findings come from an analysis of a massive 100GB data set called "COMB21" — aka Compilation of Many Breaches — that was published for free in an online cybercrime forum earlier this February by putting together data from multiple leaks in different companies and organizations that occurred over the years. It's worth noting that a leak doesn't imply a breach of public administration systems. The passwords are said to have been obtained via techniques such as password hash cracking after bein
Indian Brokerage Firm Upstox Suffers Data Breach Leaking 2.5 Millions Users' Data

Indian Brokerage Firm Upstox Suffers Data Breach Leaking 2.5 Millions Users' Data

April 12, 2021Ravie Lakshmanan
Online trading and discount brokerage platform Upstox has become the latest Indian company to suffer a security breach of its systems, resulting in the exposure of sensitive information of approximately 2.5 million users on the dark web. The leaked information includes names, email addresses, dates of birth, bank account information, and about 56 million know your customer (KYC) documents pulled from the company's server. The breach was first disclosed by independent researcher  Rajshekhar Rajaharia  on April 11. It's not immediately clear when the incident occurred. Reacting to the development, the company however said it had recently upgraded its security systems following reports of "unauthorized access into our database" while stressing that users' funds and securities remained protected. As a precaution, besides initiating a secure password reset of users' accounts, Upstox said it restricted access to the impacted database, implying it was a case
PHP Site's User Database Was Hacked In Recent Source Code Backdoor Attack

PHP Site's User Database Was Hacked In Recent Source Code Backdoor Attack

The maintainers of the PHP programming language have issued an update regarding the security incident that came to light late last month, stating that the actors may have gotten hold of a user database containing their passwords to make unauthorized changes to the repository. "We no longer believe the git.php.net server has been compromised. However, it is possible that the master.php.net user database leaked," Nikita Popov  said  in a message posted on its mailing list on April 6. On March 28, unidentified actors used the names of Rasmus Lerdorf and Popov to  push malicious commits  to the "php-src" repository hosted on the git.php.net server that involved adding a backdoor to the PHP source code in an instance of a software supply chain attack. While this was initially treated as a compromise of the git.php.net server, further investigation into the incident has revealed that the commits were a result of pushing them using HTTPS and password-based authentica
533 Million Facebook Users' Phone Numbers and Personal Data Leaked Online

533 Million Facebook Users' Phone Numbers and Personal Data Leaked Online

April 04, 2021Ravie Lakshmanan
In what's likely to be a goldmine for bad actors, personal information associated with approximately 533 million Facebook users worldwide has been leaked on a popular cybercrime forum for free—which was harvested by hackers in 2019 using a Facebook vulnerability. The  leaked data  includes full names, Facebook IDs, mobile numbers, locations, email addresses, gender, occupation, city, country, marital status broken, account creation date, and other profile details broken down by country, with over 32 million records belonging to users in the U.S., 11 million users the U.K., and six million users in India, among others. Also included in the leak are  phone numbers  from Facebook CEO Mark Zuckerberg, and co-founders Chris Hughes, and Dustin Moskovitz, who are the fourth, fifth, and sixth members to have registered on Facebook. Interestingly, it appears that the same phone number is also registered to his name on the privacy-focussed messaging app Signal. "Mark Zuckerberg als
New Zoom Screen-Sharing Bug Lets Other Users Access Restricted Apps

New Zoom Screen-Sharing Bug Lets Other Users Access Restricted Apps

March 18, 2021Ravie Lakshmanan
A newly discovered glitch in Zoom's screen sharing feature can accidentally leak sensitive information to other attendees in a call, according to the latest findings. Tracked as  CVE-2021-28133 , the unpatched security vulnerability makes it possible to reveal contents of applications that are not shared, but only briefly, thereby making it harder to exploit it in the wild. It's worth pointing out that the  screen sharing  functionality in Zoom lets users share an entire desktop or phone screen, or limit sharing to one or more specific applications, or a portion of a screen. The issue stems from the fact that a second application that's overlayed on top of an already shared application can reveal its contents for a short period of time. "When a Zoom user shares a specific application window via the 'share screen' functionality, other meeting participants can briefly see contents of other application windows which were not explicitly shared," SySS rese

Data Breach Exposes 1.6 Million Jobless Claims Filed in the Washington State

February 02, 2021Ravie Lakshmanan
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
Police Arrest 21 WeLeakInfo Customers Who Bought Breached Personal Data

Police Arrest 21 WeLeakInfo Customers Who Bought Breached Personal Data

December 25, 2020Ravie Lakshmanan
21 people have been arrested across the UK as part of a nationwide cyber crackdown targeting customers of WeLeakInfo[.]com, a now-defunct online service that had been previously selling access to data hacked from other websites. The suspects used stolen personal credentials to commit further cyber and fraud offences, the UK National Crime Agency (NCA)  said . Of the 21 arrested — all men aged between 18 and 38 — nine have been detained on suspicion of Computer Misuse Act offences, nine for Fraud offences, and three are under investigation for both. The NCA also seized over £41,000 in bitcoin from the arrested individuals. Earlier this  January , the US Federal Bureau of Investigation (FBI), the NCA, the Netherlands National Police Corps, the German Bundeskriminalamt, and the Police Service of Northern Ireland jointly  seized the domain  of WeLeakInfo.com. Launched in 2017, the service provided its users a search engine to access the personal information illegally obtained from ov
Microsoft Says Its Systems Were Also Breached in Massive SolarWinds Hack

Microsoft Says Its Systems Were Also Breached in Massive SolarWinds Hack

December 17, 2020Ravie Lakshmanan
The massive state-sponsored  espionage campaign  that compromised software maker SolarWinds also targeted Microsoft, as the unfolding investigation into the hacking spree reveals the incident may have been far more wider in scope, sophistication, and impact than previously thought. News of Microsoft's compromise was first reported by Reuters , which also said the company's own products were then used to strike other victims by leveraging its cloud offerings, citing people familiar with the matter. The Windows maker, however, denied the threat actor had infiltrated its production systems to stage further attacks against its customers. In a statement to The Hacker News via email, the company said — "Like other SolarWinds customers, we have been actively looking for indicators of this actor and can confirm that we detected malicious SolarWinds binaries in our environment, which we isolated and removed. We have not found evidence of access to production services or custom

US Agencies and FireEye Were Hacked Using SolarWinds Software Backdoor

December 13, 2020Ravie Lakshmanan
State-sponsored actors allegedly working for Russia have  targeted  the US Treasury, the Commerce Department's National Telecommunications and Information Administration (NTIA), and other government agencies to  monitor internal email traffic  as part of a widespread cyberespionage campaign. The Washington Post, citing unnamed sources, said the latest attacks were the work of APT29 or Cozy Bear, the same hacking group that's believed to have orchestrated a breach of US-based cybersecurity firm  FireEye  a few days ago leading to the theft of its Red Team penetration testing tools. The motive and the full scope of what intelligence was compromised remains unclear, but signs are that adversaries tampered with a software update released by Texas-based IT infrastructure provider SolarWinds earlier this year to infiltrate the systems of government agencies as well as FireEye and mount a highly-sophisticated  supply chain attack . "The compromise of SolarWinds' Orion Ne
Cybersecurity Firm FireEye Got Hacked; Red-Team Pentest Tools Stolen

Cybersecurity Firm FireEye Got Hacked; Red-Team Pentest Tools Stolen

December 09, 2020Ravie Lakshmanan
FireEye, one of the largest cybersecurity firms in the world, said on Tuesday it became a victim of a  state-sponsored attack  by a "highly sophisticated threat actor" that stole its arsenal of Red Team penetration testing tools it uses to test the defenses of its customers. The company said it's actively investigating the breach in coordination with the US Federal Bureau of Investigation (FBI) and other key partners, including Microsoft. It did not identify a specific culprit who might be behind the breach or disclose when the hack exactly took place. However,  The New York Times  and  The Washington Post  reported that the FBI has turned over the investigation to its Russian specialists and that the attack is likely the work of  APT29  (or Cozy Bear) — state-sponsored hackers affiliated with Russia's SVR Foreign Intelligence Service — citing unnamed sources. As of writing, the hacking tools have not been exploited in the wild, nor do they contain zero-day expl

Beware: New Android Spyware Found Posing as Telegram and Threema Apps

October 01, 2020Ravie Lakshmanan
A hacking group known for its attacks in the Middle East, at least since 2017, has recently been found impersonating legitimate messaging apps such as Telegram and Threema to infect Android devices with a new, previously undocumented malware. "Compared to the versions documented in 2017, Android/SpyC23.A has extended spying functionality, including reading notifications from messaging apps, call recording and screen recording, and new stealth features, such as dismissing notifications from built-in Android security apps," cybersecurity firm ESET  said  in a Wednesday analysis. First detailed by Qihoo 360 in 2017 under the moniker  Two-tailed Scorpion (aka APT-C-23 or Desert Scorpion), the mobile malware has been deemed "surveillanceware" for its abilities to spy on the devices of targeted individuals, exfiltrating call logs, contacts, location, messages, photos, and other sensitive documents in the process. In 2018, Symantec discovered a  newer variant  of the
