The infamous Clop ransomware gang is exploiting a zero-day vulnerability in on-prem SysAid IT automation servers.

The attacks were discovered last week by SysAid's security team, and the company released a software update to patch the exploited bug.

Tracked as CVE-2023-47246, SysAid's team described the zero-day as a "path traversal vulnerability leading to code execution."

The company says it worked with security firm Profero to investigate the attacks and found similar exploitation. Attacks involved exploiting the zero-day to gain control over the server, downloading and installing a Java webshell, and then running a series of PowerShell commands that installed the GraceWire trojan.

The attackers then used a second set of PowerShell scripts to remove traces of their intrusion and then moved to hands-on-keyboard activity on the compromised systems.

According to Microsoft's threat intel team, this involved the same Clop shenanigans of moving laterally across local networks, stealing any data they can get their hands on, and encrypting with its ransomware.

The recent attacks would make SysAid the fourth different enterprise software the gang has exploited this year after it previously targeted GoAnywhere and MOVEit file transfer servers and PaperCut print management servers.

All of these attacks are now part of Clop's regular mode of operation, which involves targeting popular enterprise software, stealing corporate data, encrypting systems, and then asking for ransoms for the decryption key or not publishing the victim's data.

The group has been doing this since late 2021 and rose to infamy after its successful mass exploitation of Accellion file transfer appliances.

On its website, SysAid says it has more than 5,000 customers, but IoT search engines like Shodan appear to see only 500 of these systems exposed on the internet.

OCCRP journalists targeted with Pegasus: Two Indian reporters from the Organized Crime and Corruption Reporting Project have had their phones targeted with the Pegasus spyware. The attacks took place hours after the two reporters reached out for comment to the Adani Group, one of India's largest companies. The reporters were investigating the Adani Group's owners for possible market manipulation by secretly buying their own stocks. OCCRP reporters Ravi Nair and Anand Mangnale are two of the 20 Indians that Apple notified in October that their phones were targeted by state-sponsored malware.

ICBC ransomware attack: The Industrial and Commercial Bank of China has suffered a ransomware attack.

Nordex BEC scam: Wind turbine giant Nordex lost $800,000 to a BEC scam after one of the company's employees paid a fake invoice to a scammer's account. The incident could have been worse since the invoice total was $1.75 million, which Nordex couldn't pay at the time. Nordex discovered the scam a month after making the initial payment. The FBI says that $50,000 of the stolen funds were sent to the bank account of Dr. Kelechi Ofoegbu, a Nigerian government official and regulator of the oil and gas industry.

Sumo Logic breach: Cloud security company Sumo Logic has disclosed a security breach after a threat actor used a set of compromised credentials to gain access to its AWS servers.

It became widely known after it became a hunting ground for pedophiles, with more than 50 criminal cases citing Omegle in court documents. [Additional coverage in the BBC]

WhatsApp Protect IP Address in Calls: Meta has announced two new security features for its WhatsApp instant messaging application. The first is named "Protect IP Address in Calls" and works by relaying all calls through WhatsApp servers in order to hide each participant's IP address from one another. The second is named "Silence Unknown Callers" and works by silencing calls from numbers that are not in a user's address book. Meta's engineering team says this second feature has a secondary side-effect of blocking zero-click exploits delivered via calling and network protocols. Meta did this by building a special protocol for delivering stripped-down, silenced call notifications and letting recipients choose to upgrade the alert to a fully-featured call.

Signal tests usernames: The Signal encrypted instant messaging service is testing support for usernames as a replacement for its current system, where real-world phone numbers serve as user identities. The new feature is currently available for the app's testers. Once finalized and released to the stable channel, users can select their usernames by going to the Settings/Profile and Settings/Privacy/Phone Number section. Signal devs did not say when they expect the new feature to launch.

In addition, Microsoft has also set up new teams to help candidates deal with cyber-influence campaigns.

SLP protocol enters abuse: CISA says threat actors are exploiting a vulnerability in the Service Location Protocol (SLP) to launch DDoS attacks in the wild. News of active exploitation comes six months after security firms said the protocol could be abused for the largest DDoS attacks known to date. Companies like Bitsight and Curesec said SLP had a DDoS amplification factor of 2,200, the third largest factor known to date. DDoS attacks abusing SLP come two weeks after a researcher posted a proof-of-concept tool on GitHub. The vulnerability that enables these attacks is tracked as CVE-2023-29552.

Chinese APT in Cambodia: Chinese state-sponsored hackers have breached at least 24 Cambodian government agencies in one of the largest compromises of the year. The intrusions were spotted by security firm Palo Alto Networks, who detected traffic going from the compromised agencies to the infrastructure of a Chinese APT group. The infrastructure had been disguised to look like cloud backup services. According to Palo Alto, hackers seem to have gained access to government agencies responsible for national defense, elections, finances, telecommunications, and natural resources.

Kremlin "influence-for-hire" firms: The US State Department says the Kremlin is using three "influence-for-hire" companies to spread its propaganda across Latin America. Officials say companies such as the Social Design Agency, the Institute for Internet Development, and Structura have helped plant pro-Russian stories with local news outlets and social media influencers. The State Department says the articles are written in Russia, translated to Spanish or Portuguese, and then sent to the three companies for promotion across local news outlets. Officials have named Ilya Gambashidze as the lead in Russia's disinformation effort in Latin America.

New Sandworm power grid attack: Russian military hackers breached the network of a Ukrainian power grid operator in June 2022 and launched a cyber-attack that crashed its OT environment to trigger a power outage in October 2022. This marks the third time since 2014 that Russian hacking group Sandworm has triggered a power outage in Ukraine using solely cyber tools. Mandiant says the cyber-attack coincided with missile strikes on critical infrastructure across Ukraine. The security firm told Wired reporter Andy Greenberg that they don't have evidence to support the theory that Russia intended the blackout and bombings to be simultaneous, but Mandiant pointed out that Sandworm held on to access to the hacked power grid for weeks prior to deploying their attack just before the kinetic missile strikes.

Defiant bug bounty program: Security firm Defiant, the maker of the Wordfence firewall plugin for WordPress sites, has launched a private bounty program. The program will work like ZDI and will pay researchers to find vulnerabilities and disclose them privately to its program. Defiant will then handle disclosing and getting a fix pushed out for the bugs.

Azure Automation Service: Security firm SafeBreach has developed several ways to abuse the Azure Automation Service and execute code without getting charged—a useful feature for crypto-mining gangs. The company released a tool named CloudMiner that exploits these loopholes, some of which have been patched by Microsoft.

NTLM leak: Check Point researchers have identified a vulnerability in Microsoft Access databases that can be used to bypass firewalls and leak a Windows user's NTLM password hash. The technique abuses a Microsoft Access feature named Linked Table that allows Access databases to link to each other's tables. Check Point says the feature is exempt from local firewall rules, allowing attackers to piggyback on it and send NTLM hashes out of a network.

Netgear vulnerability: QuarksLab has published a write-up on CVE-2023-27368, a vulnerability in the soap_serverd daemon of Netgear routers. The company used the vulnerability in the 2022 edition of the Pwn2Own Toronto hacking contest.
