Software developed by data extraction company Cellebrite contains vulnerabilities that allow arbitrary code execution on the device, claims Moxie Marlinspike, the creator of the encrypted messaging app Signal. The researcher found that Cellebrite's software had outdated open-source code that had not been updated in almost a decade, despite security updates being available.
In new reporting by Reuters, investigators have stated that hundreds of customer networks have been breached in the incident, expanding the scope of this system breach beyond just Codecov's systems. As reported by BleepingComputer last week, Codecov had suffered a supply-chain attack that went undetected for over 2-months.

Codecov online platform for hosted code testing reports and statistics announced on Thursday that a threat actor had modified its Bash Uploader script, exposing sensitive information in customers' continuous integration environment. Codecov provides tools that help developers measure how much of the source code executes during testing, a process known as code coverage, which indicates the potential for undetected bugs being present in the code.
U.S. authorities revealed this week that the FBI executed a court-authorized cyber operation to remove malicious web shells from hundreds of compromised Microsoft Exchange servers located in the United States. "The effort by the FBI, as described in the Justice Department press release, amounts to the FBI gaining access to private servers. Just that should be a full stop that the action is not ok. While I understand the good intention - the FBI wants to remove the backdoor - this sets a dangerous precedent where law enforcement is given broad permission to access private servers."
Authorities have executed a court-authorized operation to copy and remove malicious web shells from hundreds of vulnerable on-premises versions of Microsoft Exchange Server software in the United States. Through January and February 2021, certain hacking groups exploited zero-day vulnerabilities in Microsoft Exchange Server software to access email accounts and place web shells for continued access.
FBI agents executed a court-authorized cyber operation to delete malicious web shells from hundreds of previously hacked Microsoft Exchange servers in the United States, unbeknownst to their owners, the U.S. Department of Justice said Tuesday. After a wave of major in-the-wild zero-day attacks against Exchange Server installations that occurred globally in January, savvy organizations scrambled to lock down vulnerable Microsoft email servers and remove web shells that were installed by attackers.
A court-approved FBI operation was conducted to remove web shells from compromised US-based Microsoft Exchange servers without first notifying the servers' owners. On March 2nd, Microsoft released a series of Microsoft Exchange security updates for vulnerabilities actively exploited by a hacking group known as HAFNIUM. These vulnerabilities are collectively known as ProxyLogon and were used by threat actors in January and February to install web shells on compromised Exchange servers.
The organization that oversees Sweden's national sports federations was hacked by Russian military intelligence in 2017-18, officials said Tuesday, in a data-breaching campaign that also affected some of the world's leading sporting bodies, including FIFA and the World Anti-Doping Agency. Swedish prosecutors said the "Repeated and comprehensive breaches" of the Swedish Sports Confederation by GRU resulted in athletes' personal details, such as medical records, being accessed and that information being published by Swedish media.
The U.S. Cybersecurity and Infrastructure Security Agency this week published details on additional malware identified on compromised Microsoft Exchange servers, namely China Chopper webshells and DearCry ransomware. The malware operators target Exchange servers through a series of vulnerabilities that were made public on March 3, the same day Microsoft released patches for them.
