Microsoft Investigates Iranian Attacks Against the Albanian Government
(published: September 8, 2022)
Microsoft researchers discovered that groups working under Iran’s Ministry of Intelligence and Security (MOIS, tracked as OilRig) attacked the government of Albania. The attackers started with initial intrusion in May 2021, proceeded with mailbox exfiltrations between October 2021 and January 2022, organized controlled leaks, and culminated on July 15, 2022, with disruptive ransomware and wiper attacks. This attack is probably a response to the June 2021 Predatory Sparrow’s anti-Iranian cyber operations promoting the Mujahedin-e Khalq (MEK), an Iranian dissident group largely based in Albania.
Analyst Comment: MOIS attack on Albania uses messaging and targeting similar to the previous MEK-associated attack on Iran. It tells us that Iran has chosen to engage in a form of direct and proportional retaliation as it sees it. Still, the attack and its attribution caused Albania to cut diplomatic ties with Iran and expel the country's embassy staff. Organizations should implement multifactor authentication (MFA) for mailbox access and remote connectivity. Anomali platform users advised to block known OilRig network indicators.

BRONZE PRESIDENT Targets Government Officials
(published: September 8, 2022)
Secureworks researchers detected a new campaign by China-sponsored group Mustang Panda (Bronze President). In June and July 2022, the group used spearphishing to deliver the PlugX malware to government officials in Europe, the Middle East, and South America. To bypass mail-scanning antiviruses, the archived email attachment had malware embedded eight levels deep in a sequence of hidden folders named with special characters.
Analyst Comment: Many advanced attacks start with basic techniques such as unwarranted email with malicious attachment that requires the user to open it and enable macros. It is important to teach your users basic online hygiene and phishing awareness.

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.

SYK Crypter Distributing Malware Families Via Discord
(published: May 12, 2022)
Morphisec researchers discovered a new campaign abusing popular messaging platform Discord content distribution network (CDN). If a targeted user activates the phishing attachment, it starts the DNetLoader malware that reaches out to the hardcoded Discord CDN link and downloads a next stage crypter such as newly-discovered SYK crypter. SYK crypter is being loaded into memory where it decrypts its configuration and the next stage payload using hardcoded keys and various encryption methods. It detects and impairs antivirus solutions and checks for d |

Google: This Spectre proof-of-concept shows how dangerous these attacks can be
(published: March 15, 2021)
Google has released a proof of concept (PoC) code to demonstrate the practicality of Spectre side-channel attacks against a browser's JavaScript engine to leak information from its memory. Spectre targeted the process in modern CPUs called speculative execution to leak secrets such as passwords from one site to another. While the PoC demonstrates the JavaScript Spectre attack against Chrome 88's V8 JavaScript engine on an Intel Core i7-6500U CPU on Linux, Google notes it can easily be tweaked for other CPUs, browser versions and operating systems.
Analyst Comment: As the density of microchip manufacturing continues to increase, side-channel attacks are likely to be found across many architectures and are difficult (and in some cases impossible) to remediate in software. The PoC of the practicality of performing such an attack using javascript emphasises that developers of both software and hardware be aware of these types of attacks and the means by which they can be used to invalidate existing security controls.

Threat Assessment: DearCry Ransomware
(published: March 12, 2021)
A new ransomware strain is being used by actors to attack unpatched Microsoft Exchange servers. Microsoft released patches for four vulnerabilities that are being exploited in the wild. The initial round of attacks included installation of web shells onto affected servers that could be used to infect additional computers. While the initial attack appears to have been done by sophisticated actors, the ease and publicity around these vulnerabilities has led to a diverse group of actors all attempting to compromise these servers.
Analyst Comment: Patch and asset management are a critical and often under-resourced aspect of defense in depth. As this particular set of vulnerabilities and attacks are against locally hosted Exchange servers, organization may want to assess whether a hosted solution may make sense from a risk standpoint
