IntroductionIn this report, Kovrr collected and analyzed data to better understand one of the most common initial access vectors (1) - the use of compromised credentials (Valid Accounts - T1078) (2) to access internet-exposed assets (External Remote Services - T113) (3). The toxic combination of these two initial access vectors can allow malicious actors to gain a foothold in company networks before moving on to the next stage of their attack, which can be data theft, ransomware, denial of service, or any other action. There are numerous examples of breaches perpetrated by many attack groups that have occurred using this combination, for example, breaches by Lapsus (4) and APT39 (5), among others. âThis report seeks to demonstrate which industries and company sizes have the highest percentage of compromised credentials and number of internet-exposed assets and face a higher risk of having their networks breached by the toxic combination of the initial access vectors mentioned above.âIt should be noted that having an asset exposed to the internet does not inherently pose a risk or indicate that a company has poor security. In our highly digitized world, companies are required to expose services to the internet so their services can be accessed by customers, vendors, and remote employees. These services include VPN servers, SaaS applications developed by the company, databases, and shared storage units. However, there are some common cases when having an asset exposed to the internet can be extremely risky, for example:âWhen a company unintentionally exposes an asset due to misconfiguration.When a malicious third party obtains compromised credentials of a legitimate third party and accesses an exposed asset.  âTo limit unnecessary internet exposure, companies should employ the following possible mitigations:âUse Multi-Factor Authentication (MFA) for any services or assets that require a connection so that compromised credentials on their own will not be enough to breach an exposed asset.Limit access to the asset to only specific accounts, domains, and/or IP ranges.Segment the internal company network and isolate critical areas so that even if a network is breached through access to an external asset, attackers will not be able to use that access to reach wider or more sensitive areas of the company network. âSummaryâThe following are the main findings from the collected data:âThe Services industry is by far the most exposed to attackers. Companies from that industry have the highest percentage of compromised credentials (74%). However, they have a relatively low amount of internet-exposed assets per company (34%). However, given that an average cyber loss in this industry has been shown to be about $45M, this is highly concerning (6). The Services industry (SIC Division I) is followed by Division E (Transportation, Communications, Electric, Gas, and Sanitary Services, with an average loss of around $58M), which is followed by Division D (Manufacturing, with an average loss of around $25M). The revenue range for companies with the highest number of compromised credentials is $1M-$10M, followed by $10M-$50M. A similar trend is also observed when evaluating company size by the number of employees. Indeed, companies with fewer employees have a higher share of compromised credentials. On average, the larger the company (both in terms of revenue and number of employees (7)), the greater the number of internet-exposed assets.There is a correlation between the industries and revenue ranges of companies targeted by ransomware and those with the highest share of compromised credentials.   âMethodologyâThe data for this research was collected as follows:âData regarding compromised credentials was first collected from Hudson Rock, a provider of various cybercrime data. Data was collected for the previous six months, beginning March 2023. This data | Ransomware Threat Studies Prediction Cloud | APT 39 APT 39 APT 17 | ★★★ |

The Ransomware Threat Landscape H1-23This report provides a comprehensive analysis of all known ransomware attacks that were reported during the first two quarters of 2023.Read More (lien direct) |
IntroductionâIn this comprehensive report, Kovrr collected and analyzed data on all known ransomware attacks reported during the first two quarters of 2023. The data was collected from multiple sources, all aggregated and updated regularly in Kovrrâs Threat Intelligence Database. The database includes data on many different types of cyber incidents, but this report includes only data on ransomware attacks, excluding data on any other type of attacks. The ransomware groups covered in this report all operate as a RaaS (Ransomware as a Service), a business model through which the ransomware binary and operation are sold or leased to operators, called affiliates. This means that a ransomware operation is composed of many different individuals, with separate roles, and the extortion profits are divided between them. Some individuals are responsible for initial access to the targets, others to lateral movement to interesting and profitable areas in the victim network, while others are responsible for the ransomware infection itself, and others negotiate with the victim after infection. âSummaryâThese are the main insights from the collected data:There is a 32% drop in attack amounts in H1-23 compared to H2-22. It is important to note that this drop can also be due to delayed reporting of cyber incidents by attacked companies.The top ten most active groups observed during the first half of 2023 are AvosLocker, Bianlian, BlackBasta, BlackCat, Clop, Lockbit 3.0, MedusaLocker, Play, Royal, and ViceSociety. All 10 actors accounted for 87% of attacks during this period, while the top 3 groups (Lockbit 3.0, BlackCat, and Clop) accounted for 53% of all claimed attacks during this period. The average lifespan of a ransomware group is 262 days, while the median is 167 days. In an average month, 18.3 different ransomware groups are active.The most targeted industry is the Services industry, while companies with a revenue of $10M-$50M are the most common targets. âData Collection Methods and Possible BiasesâThe data for this research was collected from Kovrrâs Threat Intelligence Database, that collects data from multiple sources, and includes information on different types of cyber incidents. Specifically for this report, data was collected mainly from ransomware leak sites, public filings of attacked companies, and news reports on ransomware attacks. The data from ransomware leak sites was collected mainly from Double Extortion (https://doubleextortion.com), a data source providing up to date information from ransomware leak sites. The rest of the data was collected using proprietary sources and methods. This data was then combined with additional sources to collect company business information and is limited to ransomware attacks that occurred and were reported in the first two quarters of 2023, between January 1st 2023 and June 31st 2023. There are several possible biases in the data that may affect the results presented in the report. Data collection for this research relied either on a company filing a notification on a ransomware attack, or a ransomware group uploading information about a victim. Therefore, in the case that a company decided not to file a notice of a ransomware attack, for example due to not being legally required to do so, it will not be included in our data. This means that companies located in countries that require data breach notifications, such as companies in the United States or the European Union, are expected to have a higher representation in our data. This is also true for companies in more regulated industries, such as healthcare. Regarding data retrieved from ransom group sites, there may be cases where an attacker did not upload data on the attack victim, as the victim paid the ransom, or for other reasons. This means that some victims that have quickly paid ransoms following an attack might not appear in our data. Additionally,, we have previously researched | Ransomware Data Breach Vulnerability Threat Cloud | APT 17 | ★★★ |

[Eyes Open] The FTC Reveals the Latest Top Five Text Message Scams
The U.S. Federal Trade Commission (FTC) has published a data spotlight outlining the most common text message scams. Phony bank fraud prevention alerts were the most common type of text scam last year. "Reports about texts impersonating banks are up nearly tenfold since 2019 with median reported individual losses of $3,000 last year," the report says.
These are the top five text scams reported by the FTC:
Copycat bank fraud prevention alerts
Bogus "gifts" that can cost you
Fake package delivery problems
Phony job offers
Not-really-from-Amazon security alerts
"People get a text supposedly from a bank asking them to call a number ASAP about suspicious activity or to reply YES or NO to verify whether a transaction was authorized. If they reply, they\'ll get a call from a phony \'fraud department\' claiming they want to \'help get your money back.\' What they really want to do is make unauthorized transfers.
"What\'s more, they may ask for personal information like Social Security numbers, setting people up for possible identity theft."
Fake gift card offers took second place, followed by phony package delivery problems. "Scammers understand how our shopping habits have changed and have updated their sleazy tactics accordingly," the FTC says. "People may get a text pretending to be from the U.S. Postal Service, FedEx, or UPS claiming there\'s a problem with a delivery.
"The text links to a convincing-looking – but utterly bogus – website that asks for a credit card number to cover a small \'redelivery fee.\'"
Scammers also target job seekers with bogus job offers in an attempt to steal their money and personal information. "With workplaces in transition, some scammers are using texts to perpetrate old-school forms of fraud – for example, fake \'mystery shopper\' jobs or bogus money-making offers for driving around with cars wrapped in ads," the report says.
"Other texts target people who post their resumes on employment websites. They claim to offer jobs and even send job seekers checks, usually with instructions to send some of the money to a different address for materials, training, or the like. By the time the check bounces, the person\'s money – and the phony \'employer\' – are long gone."
Finally, scammers impersonate Amazon and send fake security alerts to trick victims into sending money. "People may get what looks like a message from \'Amazon,\' asking to verify a big-ticket order they didn\'t place," the FTC says. "Concerned |

Hacker Pwns Uber Via Compromised VPN Account
(published: September 16, 2022)
On September 15, 2022, ride-sharing giant Uber started an incident response after discovering a data breach. According to Group-IB researchers, download file name artifacts point to the attacker getting access to fresh keylogger logs affecting two Uber employees from Indonesia and Brazil that have been infected with Racoon and Vidar stealers. The attacker allegedly used a compromised VPN account credentials and performed multifactor authentication fatigue attack by requesting the MFA push notification many times and then making a social-engineering call to the affected employee. Once inside, the attacker allegedly found valid credentials for privilege escalation: a PowerShell script containing hardcoded credentials for a Thycotic privileged access management admin account. On September 18, 2022, Rockstar Games’ Grand Theft Auto 6 suffered a confirmed data leak, likely caused by the same attacker.
Analyst Comment: Network defenders can consider setting up alerts for signs of an MFA fatigue attack such as a large number of MFA requests in a relatively short period of time. Review your source code for embedded credentials, especially those with administrative privileges.

2022-08-18 08:00:00 | Ukraine and the fragility of agriculture security (lien direct) |  By Joe Marshall.The war in Ukraine has had far-reaching global implications and one of the most immediate effects felt will be on the global supply chain for food. This war-induced fragility has exposed the weaknesses of how we feed ourselves globally. Ransomware cartels and other adversaries are well aware of this and are actively exploiting that fragility. For the past six years, Cisco Talos has been actively involved in assisting public and private institutions in Ukraine to defend themselves against state-sponsored actors. Our involvement stretches the gamut from commercial to critical infrastructure, to election security. Our presence has afforded us unique opportunities and observations about cybersecurity in a macro and micro way. Ukraine has been a frequent victim of state-sponsored cyber attacks aimed at critical infrastructures like power and transportation. Talos is proud to stand with our partners in Ukraine and help defend their critical networks and help users there maintain access to necessary services. Now that Russia has invaded Ukraine, those threats have escalated to kinetic attacks that are wreaking havoc on a critical element of our world: agriculture and our global food supply chain. Even worse is the implications this war will have for future cyber attacks, as fragility is considered a lucrative element in deciding victimology by threat actors like ransomware cartels. To truly grasp the implications of the war in Ukraine, we have to examine how vital Ukrainian agriculture feeds the world, the current state of affairs, and what this means for the global cybersecurity posture to protect agricultural assets. Where there is weakness, there is opportunityRansomware cartels and their affiliates are actively targeting the agricultural industry. Moreover, these actors have done their homework and are targeting agricultural companies during the two times of the year where they cannot suffer disruptions: planting and harvesting. Per the published FBI PIN Alert: “Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production.” This is far from unusual for these adversaries - they are shrewd and calculating, and understand their victims' weaknesses and industries.

Credit Card Stealer Targets PsiGate Payment Gateway Software
(published: May 25, 2022)
Sucuri Researchers have detailed their findings on a MageCart skimmer that had been discovered within the Magento payment portal. Embedded within the core_config_data table of Magento’s database, the skimmer was obfuscated and encoded with CharCode. Once deobfuscated, a JavaScript credit card stealer was revealed. The stealer is able to acquire text and fields that are submitted to the payment page, including credit card numbers and expiry dates. Once stolen, a synchronous AJAX is used to exfiltrate the data.
Analyst Comment: Harden endpoint security and utilize firewalls to block suspicious activity to help mitigate against skimmer injection. Monitor network traffic to identify anomalous behavior that may indicate C2 activity.

How the Saitama Backdoor uses DNS Tunneling
(published: May 25, 2022)
MalwareBytes Researchers have released their report detailing the process behind which the Saitama backdoor utilizes DNS tunneling to stealthy communicate with command and control (C2) infrastructure. DNS tunneling is an effective way to hide C2 communication as DNS traffic serves a vital function in modern day internet communications thus blocking DNS traffic is almost never done. Saitama formats its DNS lookups with the structure of a domain consisting of message, counter . root domain. Data is encoded utilizing a hardcoded base36 alphabet. There are four types of messages that Saitama can send using this method: Make Contact to establish communication with a C2 domain, Ask For Command to get the expected size of the payload to be delivered, Get A Command in which Saitama will make Receive requests to retrieve payloads and instructions and finally Run The Command in which Saitama runs the instructions or executes the payload and sends the results to the established C2.
Analyst Comment: Implement an effective DNS filtering system to block malicious queries. Furthermore, maintaining a whitelist of allowed applications for installation will assist in preventing malware like Saitama from being installed.

COBALT MIRAGE Conducts Ransomware Operations in U.S.
(published: May 12, 2022)
Secureworks researchers describe campaigns by Iran-sponsored group Cobalt Mirage. These actors are likely part of a larger group, Charming Kitten (Phosphorus, APT35, Cobalt Illusion). In 2022, Cobalt Mirage deployed BitLocker ransomware on a US charity systems, and exfiltrated data from a US local government network. Their ransomware operations appear to be a low-scale, hands-on approach with rare tactics such as sending a ransom note to a local printer. The group utilized its own custom binaries including a Fast Reverse Proxy client (FRPC) written in Go. It also relied on mass scanning for known vulnerabilities (ProxyShell, Log4Shell) and using commodity tools for encryption, internal scanning, and lateral movement.
Analyst Comment: However small your government or NGO organization is, it still needs protection from advanced cyber actors. Keep your system updated, and employ mitigation strategies when updates for critical vulnerabilities are not available.

A Lookback Under the TA410 Umbrella: Its Cyberespionage TTPs and Activity
(published: April 28, 2022)
ESET researchers found three different teams under China-sponsored umbrella cyberespionage group TA410, which is loosely linked to Stone Panda (APT10, Chinese Ministry of State Security). ESET named these teams FlowingFrog, JollyFrog, and LookingFrog. FlowingFrog uses the Royal Road RTF weaponizer described by Anomali in 2019. Infection has two stages: the Tendyron implant followed by a very complex FlowCloud backdoor. JollyFrog uses generic malware such as PlugX and QuasarRAT. LookingFrog’s infection stages feature the X4 backdoor followed by the LookBack backdoor. Besides using different backdoors and exiting from IP addresses located in three different districts, the three teams use similar tools and similar tactics, techniques, and procedures (TTPs).
Analyst Comment: Organizations should keep their web-facing applications such as Microsoft Exchange or SharePoint secured and updated. Educate your employees on handling suspected spearphishing attempts. Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from APTs, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place.

[Heads Up] FBI Warns Against New Criminal QR Code Scams
QR codes have been around for many years. While they were adopted for certain niche uses, they never did quite reach their full potential. They are a bit like Rick Astley in that regard, really popular for one song, but well after the boat had sailed. Do not get me wrong, Rick Astley achieved a lot. In recent years, he has become immortalized as a meme and Rick roller, but he could have been so much more.
However, in recent years, with lockdown and the drive to keep things at arms length, QR codes have become an efficient way to facilitate contactless communications, or the transfer of offers without physically handing over a coupon. As this has grown in popularity, more people have become familiar with how to generate their own QR codes and how to use them as virtual business cards, discount codes, links to videos and all sorts of other things.
QRime Codes
As with most things, once they begin to gain a bit of popularity, criminals move in to see how they can manipulate the situation to their advantage. Recently, we have seen fake QR codes stuck to parking meters enticing unwitting drivers to scan the code, and hand over their payment details believing they were paying for parking, whereas they were actually handing over their payment information to criminals.
The rise in QR code fraud resulted in the FBI releasing an advisory warning against fake QR codes that are being used to scam users. In many cases, a fake QR code will lead people to a website that looks like the intended legitimate site. So, the usual verification process of checking the URL and any other red flags apply.

Targeted Attack Campaign Against ManageEngine ADSelfService Plus Delivers Godzilla Webshells, NGLite Trojan and KdcSponge Stealer
(published: November 8, 2021)
US Cybersecurity and Infrastructure Security Agency (CISA) has released an alert about advanced persistent threat (APT) actors exploiting vulnerability in self-service password management and single sign-on solution known as ManageEngine ADSelfService Plus. PaloAlto, Microsoft & Lumen Technologies did a joint effort to track, analyse and mitigate this threat. The attack deployed a webshell and created a registry key for persistence. The actor leveraged leased infrastructure in the US to scan hundreds of organizations and compromised at least nine global organizations across technology, defense, healthcare and education industries.
Analyst Comment: This actor has used some unique techniques in these attacks including: a blockchain based legitimate remote control application, and credential stealing tool which hooks specific functions from the LSASS process. It’s important to make sure your EDR solution is configured to and supports detecting such advanced techniques in order to detect such attacks.

S.O.V.A. – A New Android Banking Trojan with Fowl Intentions
(published: September 10, 2021)
ThreatFabric researchers have discovered a new Android banking trojan called S.O.V.A. The malware is still in the development and testing phase and the threat actor is publicly-advertising S.O.V.A. for trial runs targeting banks to improve its functionality. The trojan’s primary objective is to steal personally identifiable information (PII). This is conducted through overlay attacks, keylogging, man-in-the-middle attacks, and session cookies theft, among others. The malware author is also working on other features such as distributed denial-of-service (DDoS) and ransomware on S.O.V.A.’s project roadmap.
Analyst Comment: Always keep your mobile phone fully patched with the latest security updates. Only use official locations such as the Google Play Store / Apple App Store to obtain your software, and avoid downloading applications, even if they appear legitimate, from third-party stores. Furthermore, always review the permissions an app will request upon installation.

Finding Azurescape – Cross-Account Container Takeover in Azure Container Instances
(published: September 9, 2021)
Unit 42 researchers identified and disclosed critical security issues in Microsoft’s Container-as-a-Service (CaaS) offering that is called Azure Container Instances (ACI). A malicious Azure user could have compromised the multitenant Kubernetes clusters hosting ACI, establishing full control over other users' containers. Researchers gave the vulnerability a specific name, Azurescape, highlighting its significance: it the first cross-account container takeover in the public cloud.
Analyst Comment: Azurescape vulnerabilities could have allowed an attacker to execute code on other users' containers, steal customer secrets and images deployed to the platform, and abuse ACI's infrastructure processing power. Microsoft patched ACI shortly after the discl |

Shutdown Kaseya VSA Servers Now Amidst Cascading REvil Attack Against MSPs, Clients
(published: July 4, 2021)
A severe ransomware attack reportedly took place against the popular remote monitoring and management (RMM) software tool Kaseya VSA. On July 2, 2021, Kaseya urged users to shut down their VSA servers to prevent them from being compromised. The company estimated that fewer than 40 of their customers worldwide were affected, but as some of them were managed service providers (MSPs), over 1,000 businesses were infected. The majority of known victims are in the US with some in Europe (Sweden) and New Zealand. The attackers exploited a zero-day vulnerability in Kaseya’s systems that the company was in the process of fixing. It was part of the administrative interface vulnerabilities in tools for system administration previously identified by Wietse Boonstra, a DIVD researcher. The REvil payload was delivered via Kaseya software using a custom dropper that dropped two files. A dropper opens an old but legitimate copy of Windows Defender (MsMpEng.exe) that then side loads and executes the custom malicious loader's export. The attack coincided with the start of the US Independence Day weekend, and has several politically-charged strings, such as “BlackLivesMatter” Windows registry key and “DTrump4ever” as a password.
Analyst Comment: Kaseya VSA clients should safely follow the company’s recommendations as it advised shutting Kaseya VSA servers down, and is making new security updates available. Every organization should have a ransomware disaster recovery plan even if it is serviced by a managed service provider (MSP).

IndigoZebra APT Continues To Attack Central Asia With Evolving Tools
(published: July 1, 2021)
Researchers from Check Point have identified the Afghan Government as the latest victim in a cyber espionage campaign by the suspected Chinese group ‘IndigoZebra’. This attack began in April when Afghan National Security Council (NSC) officials began to receive lure emails claiming to be from the President’s secretariat. These emails included a decoy file that would install the backdoor ‘BoxCaon’ on the system before reaching out to the Dropbox API to act as a C&C server. The attacker would then be able to fingerprint the machine and begin accessing files. I |

2020-01-22 09:00:00 | NBlog Jan 22 - further lessons from Travelex (lien direct) |  At the bottom of a Travelex update on their incident, I spotted this yesterday:Customer PrecautionsBased on the public attention this incident has received, individuals may try to take advantage of it and attempt some common e-mail or telephone scams. Increased awareness and vigilance are key to detecting and preventing this type of activity. As a precaution, if you receive a call from someone claiming to be from Travelex that you are not expecting or you are unsure about the identity of a caller, you should end the call and call back on 0345 872 7627. If you have any questions or believe you have received a suspicious e-mail or telephone call, please do not hesitate to contact us. Although I am not personally aware of any such 'e-mail or telephone scams', Travelex would know better than me - and anyway even if there have been no scams as yet, the warning makes sense: there is indeed a known risk of scammers exploiting major, well-publicised incidents such as this. We've seen it before, such as fake charity scams taking advantage of the public reaction to natural disasters such as the New Orleans floods, and - who knows - maybe the Australian bushfires.At the same time, this infosec geek is idly wondering whether the Travelex warning message and web page are legitimate. It is conceivable that the cyber-criminals and hackers behind the ransomware incident may still have control of the Travelex domains, webservers and/or websites, perhaps all their corporate comms including the Travelex Twitter feeds and maybe even the switchboard behind that 0345 number. I'm waffling on about corporate identity theft, flowing on from the original incident.I appreciate the scenario I'm postulating seems unlikely but bear with me and my professional paranoia for a moment.
