COVID-19 — Phishing attacks target employees that come back to the office

The email’s body appears to have been sent from within the firm, having the firm’s logo in the header and being signed impersonating the CIO. The threat actor, posing as an executive, wrote a bogus newsletter describing the new safeguards and adjustments to business operations that the organization is implementing in response to the pandemic,” according to the Cofense research. The emails were crafted to steal company and personal credentials, they include a link to a fake Microsoft SharePoint page with two documents that outline new business operations.

Half-Double Rowhammer Vulnerability Even Targets The Latest Chips

Security researchers from Google have shared details of a new Rowhammer vulnerability ‘Half-Double’ in a recent post. Rowhammer, first discovered in 2014, has been a major hardware security risk for DRAM chips for years. During this time, numerous iterations of this vulnerability have surfaced online that even affect the latest DDR3 and DDR4 chips. Even in early 2021, researchers shared details about another variant “SMASH” that impacts some of the latest DDR4 RAM cards. In the latest case of Half-Double, the researchers observed Rowhammer effects spreading beyond the adjacent rows. Though this happens with reduced strength. Still, it contrasts the traditional belief for Rowhammer to operate at a distance of one row.

The researchers have further explained this bug in a detailed white paper on GitHub. As they confirmed, by exploiting Half-Double, they could easily trigger errors on systems with the latest chips. Though, this bug doesn’t affect the older systems, highlighting the importance of shrinkage in cell geometries. Besides, Half-Double isn’t similar to the previously known Rowhammer (2014), TRRespass (2020), or other flaws. Due to the novelty of this vulnerability, it remains unaffected by the traditional Rowhammer defense mechanisms.
