Cisco Talos has observed new cyber attacks targeting Turkey and other Asian countries we believe with high confidence are from groups operating under the MuddyWater umbrella of APT groups. U.S. Cyber Command recently connected MuddyWater to Iran's Ministry of Intelligence and Security (MOIS).
Des milliers de particuliers et d’entreprises européennes sont sans connexion depuis le 24 février. De plus en plus d’éléments pointent vers le sabotage d’un satellite, en lien avec le conflit ukrainien.
Geneva is a genetic algorithm that automatically learns how to evade nation state censors.
A new reflection/amplification distributed denial of service (DDoS) vector with a record-breaking potential amplification ratio of 4,294,967,296:1 has been abused by attackers in the wild to launch multiple high-impact DDoS attacks.
New method also stretches out DDoS durations to 14 hours.
Belarus conducted widespread phishing attacks against members of the Polish military as well as Ukrainian officials, security researchers said Monday, providing more evidence that its role in Russia’s invasion of Ukraine has gone beyond serving as a staging area for Russian troops
The prolific China APT41 hacking group, known for carrying out espionage in parallel with financially motivated operations, has compromised multiple U.S. state government networks, according to cybersecurity giant Mandiant. The group — seemingly undeterred by U.S. indictments against five APT41 members in 2020 — conducted a months-long campaign during which it targeted and successfully breached […]
The National Security Agency (NSA) has released a new Cybersecurity Technical Report (CTR): Network Infrastructure Security Guidance. The report captures best practices based on the depth and breadth of experience in supporting customers and responding to threats.
Recommendations include perimeter and internal network defenses to improve monitoring and access controls throughout the network.
Si les sanctions économiques contre la Russie ont un impact significatif, il en est autrement de celles imposées dans le domaine cyber.
Online security is extremely important for people in Ukraine and the surrounding region right now. Government agencies, independent newspapers and public service providers need it to function and individuals need to communicate safely. Google’s Threat Analysis Group (TAG) has been working around the clock, focusing on the safety and security of our users and the platforms that help them access and share important information.
Mozilla has pushed out-of-band software updates to its Firefox web browser to contain two high-impact security vulnerabilities, both of which it says are being actively exploited in the wild.
Samsung Electronics confirmed on Monday that its network was breached and the hackers stole confidential information, including source code present in Galaxy smartphones.
This is the story of CVE-2022-0847, a vulnerability in the Linux kernel since 5.8 which allows overwriting data in arbitrary read-only files. This leads to privilege escalation because unprivileged processes can inject code into root processes.
It is similar to CVE-2016-5195 “Dirty Cow” but is easier to exploit.
The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102.
Despite the fact that it is not a 'real' vulnerability, escaping privileged Docker containers is nevertheless pretty funny. And because there will always be people who will come up with reasons or excuses to run a privileged container (even though you really shouldn't), this could really be handy at some point in the future
The Lapsus$ data extortion group leaked today a huge collection of confidential data they claim to be from Samsung Electronics, the South Korean giant consumer electronics company.
Chipmaker has until Friday to comply or see its crown-jewel source code released.
Threat actors are using stolen NVIDIA code signing certificates to sign malware to appear trustworthy and allow malicious drivers to be loaded in Windows.
This week, NVIDIA confirmed that they suffered a cyberattack that allowed threat actors to steal employee credentials and proprietary data.
If you use an Apple Macbook, it’s likely that you have a secret enclave for important secrets — such as your encryption keys. These keys define the core of the trust infrastructure on the device — and protect applications from stealing these secrets. The TEE also allows isolation between code which is fully trusted, and code that cannot be fully trusted. If this did not happen, we could install applications on our computer which would discover our login password and steal the encryption used used to key things secret and trusted.
On Feb. 4, Linux announced CVE-2022-0492, a new privilege escalation vulnerability in the kernel. CVE-2022-0492 marks a logical bug in control groups (cgroups), a Linux feature that is a fundamental building block of containers. The issue stands out as one of the simplest Linux privilege escalations discovered in recent times: The Linux kernel mistakenly exposed a privileged operation to unprivileged users.
Earlier today, I received a scam email that impersonates the Ukrainian Red Cross. It attempts to solicit donations via Bitcoin. The email is almost certainly not related to any valid Red Cross effort.
There are some legitimate efforts to collect donations for Ukraine using crypto-currencies. This scam may take advantage of these efforts.
