Almost 10% of all internet-accessible SugarCRM servers (representing 291 of 3,066 servers, based on Censys data) were hacked and compromised using a zero-day exploit published online in late December.
SugarCRM describes the zero-day as an authentication bypass that allows threat actors to upload encoded images containing malicious PHP code on SugarCRM platforms.
Censys researchers say the final payload in many attacks appears to be a simple web shell that could be used to control compromised systems. According to an open-source report, the zero-day appears to have been used to drop crypto-mining malware as well.
SugarCRM released an official patch a week after public disclosure. The company said that all users who run on-premise servers of its SugarCRM Sell, Serve, Enterprise, Professional, and Ultimate services should apply the update to avoid future attacks.
The company says it has hired a forensics firm to investigate the one-week time window during which its cloud platform was exposed to possible attacks.
No CVE has been assigned to this issue yet.

The project was first announced in January last year. A recording of the press conference and the consortium's plans is embedded below.
US Supreme Court denies NSO Group: The US Supreme Court has declined to hear a petition brought by infamous Israeli spyware vendor NSO Group related to its WhatsApp lawsuit. Meta sued NSO Group in 2019 after the company created and sold an exploit that was used to hack the smartphones of tens of WhatsApp users across the globe. Meta asked a US court for an injunction banning NSO Group from developing future exploits. As part of its legal defense, NSO argued that it was entitled to "sovereign immunity" because the exploit was bought and used by foreign governments that had the authority to use such tools. Lower US courts declined NSO's petition and request for "sovereign immunity," and with the Supreme Court ruling the same, the case is now free to move forward. According to the Knight Institute at Columbia University, the decision clears the path for lawsuits by journalists and activists.
DOI password audit: The Inspector General at the Office of the Interior carried out a security audit of the password management policies used inside the US Department of the Interior. In a report [PDF] published last week, officials said they were able to crack more than 18,000 of the department's AD accounts, representing 21% of the department's entire userbase. Officials said the DOI failed to enforce password complexity requirements, failed to protect 89% of high-value accounts with a form of multi-factor authentication, failed to enforce password age limits, failed to enforce password reuse policies, and also failed to deactivate inactive accounts.

Cybercrime and threat intel
Auction site scammer sentenced: A Romanian national was sentenced to 89 months in prison for his role in a large cybercrime gang that defrauded Americans. The group operated by using stolen identities to create accounts on popular online auction sites, such as eBay, where they posted ads for non-existing goods, and then laundered their ill-gotten funds through cryptocurrency. The man is the fifth member of the gang to plead guilty and receive a long prison sentence. Four other Romanian nationals also previously received prison sentences between 61 and 70 months last year, according to the DOJ.

All systems appear to have been compromised via a Mitel zero-day (CVE-2022-29499) that was disclosed last April and which the Lorenz gang is known to have abused in previous months, per reports from Arctic Wolf and Crowdstrike.
Kinsing attacks: Microsoft has published a report that takes a deep look at the techniques used by the Kinsing cryptomining botnet to breach Kubernetes clusters. According to Microsoft, Kinsing operators preferred two methods. The first targets outdated server images that come pre-packaged with vulnerable applications. The second method targeted Kubernetes clusters that ran misconfigured PostgreSQL databases.
Malware technical reports
URSNIF: The fantastic team at the DFIR Report has published a new report that goes into the finer details of a URSNIF attack. The intrusion started with an ISO file and ended six days later after the attackers extracted access credentials from the company's network. According to the DFIR Report team, "the threat actor was able to RDP to a backup server using the admin credentials they acquired."
Raspberry Robin partial takedown: Cybersecurity firm Sekoia says the Raspberry Robin lost 80 (30%) of its command and control (C&C) servers in October last year as part of a partial takedown operation. The company's report takes a look at how the botnet's operators reacted after losing a large chunk of their servers.
"These domains had their DNS zone deleted and the tags clientHold, clientTransferProhibited were added to their status codes, leading to a total loss by the botnet operators."
APTs and cyber-espionage
PlugX analysis: Malware researcher Tìm Kiếm has published a technical analysis of a recently discovered PlugX malware sample. The malware is typically used by Chinese APTs, but Kiếm makes no formal attribution.
Hive's XDR33 variant: Netlab, the network security division of Chinese security firm Qihoo 360, says it discovered a new malware strain named XDR33 that appears to be a new variation of Hive, a malware control framework supposedly developed by the CIA. Hive is one of the tools that had its documentation leaked by WikiLeaks in 2017 as part of the Vault7 collection. Netlab researchers said they discovered the XDR33 variant last year in October being deployed on F5 devices, where the malware would act as a backdoor. Netlab says this is the first time they found a variant of the CIA Hive malware kit in the wild. Netlab didn't attribute XDR33 and the recent attacks to the CIA, at least, not yet. The report comes after China's CERT agency issued an alert in April last year about attacks carried out with the CIA's Hive malware—attacks which they directly attributed to the CIA.
StrongPity APT: ESET researchers have uncovered a new operation carried out by the StrongPity APT where the group created a website that impersonated Shagle, a video chat service that lets users have encrypted video chats with random strangers. ESET says StrongPity's goal was to get users to download and install an Android app that was a modified version of the open-source Telegram app, repackaged with one of the group's backdoors.
Vulnerabilities and bug bounty
Threema vulnerabilities: A team of academics from the ETH Zurich University has published a technical paper on a series of vulnerabilities in Threema, a secure end-to-end encrypted messaging service that bills itself as a Signal and WhatsApp alternative. The seven vulnerabilities can allow a threat actor to impersonate a user, gain access to Threema servers, and gain access to Threema data on an unlocked device. Responding to the research, Threema said the vulnerabilities impact an older version of its protocol "that is no longer in use." The company's response turned out to be both dismissive and misleading and the research team said their work is what forced the company to update to its curent and a newer protocol.
$1 million bounty: A security researcher was awarded a $1 million bug bounty reward after discovering and reporting a vulnerability that impacted three parachains running on the Polkadot blockchain, namely the Moonbeam, Astar Network, and Acala projects. According to cryptocurrency news outlet The Block, the researcher said that if the vulnerability had been exploited in the wild, an attacker could have stolen as much as $200 million worth of crypto-assets from the three projects.
Experian website bug: Credit reporting agency Experian has patched a bug in its website that allowed identity thieves to view credit reports and the personal details of any of the company's customers. The bug was super simple to exploit and consisted of replacing a part of the Experian website URL in the security questions page (/acr/oow/ with /acr/report/). According to KrebsOnSecurity, the issue was discovered last year by a Ukrainian security researcher who saw it mentioned on Telegram channels dedicated to online fraud.
Taking over a dead IoT company: Security researcher Kevin Chung has taken over an old domain used by NYCTrainSign, a now-defunct company that sold displays that show the time until a certain NYC train would hit a certain train station.
